| name | greenlight |
| description | Automated PR review loop that keeps running until the PR is clean. Triggers
external reviewers (Codex bot, Codex CLI, and the Gemini bot when activity
detection sees it on the repo), processes feedback, fixes issues, and
re-triggers — repeating until no new suggestions remain.
Supports `/greenlight external` to skip internal review and go straight to
external reviewers, and `/greenlight external gemini` to specify a starting
reviewer. Use when the user says "greenlight", "run reviews until clean",
"get this PR approved", or wants automated review cycling on an open PR.
Also auto-detects uncommitted mode: when on main branch with uncommitted
changes and no PR, runs Codex CLI `--uncommitted` review loop only, fixes
in-place without committing, until codex reports clean.
Also supports post-commit mode (explicit `/greenlight post-commit <SHA>`
or `<SHA1>..<SHA2>`): Phase 1 subagents + Codex CLI + agy (Gemini-family CLI)
in parallel, fixes as new commits on top (no amend, no new PR), pushes after
each round.

Greenlight
Automated review loop. Three modes:
Arguments
| Argument | Description | Example |
|---|
external | Skip Phase 1 + 2 (internal review), jump to Phase 3 (PR mode only) | /greenlight external |
codex bot / codex cli / gemini | Specify starting reviewer (combinable with external, PR mode only) | /greenlight external gemini |
unattended | Never prompt — on reviewer exhaustion, log and exit non-zero (fail fast). Passed by unattended callers (todos-babysit auto mode, autopilot dispatch). | /greenlight external unattended |
size=s|m|l | Advisory starting size for the S/M/L profile. Upward-only — greenlight recomputes size from the real diff and takes max, so this can raise but never lower review weight. Passed by autopilot from the plan's size field. | /greenlight size=m |
post-commit [<SHA>|<FROM>..<TO>] | Force post-commit mode on a commit / range on main (pushed or local-only) | /greenlight post-commit c1e7e256 |
Parsing rules:
post-commit keyword (case-insensitive): forces post-commit mode regardless of repo
state. Remainder is the SHA spec (single SHA, FROM..TO range, or empty to ask).
Other args are ignored.external keyword (case-insensitive): PR mode only. Remainder is the reviewer spec.unattended keyword (case-insensitive): fail-fast, no prompts. Stripped before
reviewer-spec parsing; combinable with any mode.size= token (case-insensitive, value s/m/l): advisory size for the
S/M/L profile, used in PR mode. Stripped before
reviewer-spec parsing, like unattended; a malformed value is ignored. Not read
in post-commit mode (it computes size from the resolved range) or uncommitted mode
(unsized).- No keyword: mode comes from auto-detection (see Step 1 table).
Arguments other than post-commit are ignored in Uncommitted mode and
Post-commit mode — those modes have fixed flows.
Verification gate
An optional adversarial verification gate can run between consolidating review
findings and dispatching a fix subagent: each consolidated finding is independently
challenged by 3 skeptic subagents inside one Claude Code
Workflow, and findings a majority of
skeptics refute are dropped. Only survivors reach the fix subagent. Purpose: cut
false-positive fix cycles — a wrongly "fixed" false positive costs a whole extra
review round.
Availability check. The gate runs ONLY when BOTH conditions hold: the effective
size is L (see Sizing — S and M skip the gate
regardless of tooling), AND the Workflow tool is present in the current session
(Claude Code v2.1.154+, paid plans). Before each gate, check both:
- Size L and
Workflow present → run the gate. The script, VERDICT_SCHEMA,
args contract, verdict rule, and result mapping are defined once in
references/adversarial-verify.md.
- Size S or M, or
Workflow absent → skip the gate entirely; the flow is
exactly today's flow — hand every consolidated finding straight to the fix
subagent. The gate is never a hard dependency of greenlight.
The gate applies at exactly three points, each carrying a short callout below:
PR-mode Phase 2a→2b, Post-commit Phase 1→Phase 2, and Post-commit Phase 3
Step 3→Step 4. It does NOT apply to Uncommitted mode or PR-mode Phase 3
(external review threads carry GitHub resolve/reply obligations and are already
evaluated per-thread through receiving-code-review).
Rejected findings still count. Gate-rejected findings count as "items pushed
back" in the final report, and their reasoning must be carried into later rounds'
"prior push-backs" context so a repeat finding can push-back-exit.
Inner verify loop (objective verifier gate)
Every fix dispatch that ends in a commit is wrapped in an inner verify loop:
after the fix subagent edits, it runs an objective verify command against the
working tree before committing, and may commit + push only once that command
passes. This is a different question from the reviewer-clean stopping criterion —
keep the two roles separate:
- Verifier (objective, runs code) — gates whether a fix may push. It
executes the repo's own lint / typecheck / fast-unit command and observes real
behavior (import errors, type errors, regressions).
- Reviewer-clean (subjective, reads diffs) — gates whether the outer loop may
stop. Codex / agy read the diff statically; they cannot run code, so they
are not verifiers. Do not conflate the two, and never position codex/agy as
the verifier.
Applies to the PR-mode Phase 2b, PR-mode Phase 3 (Step 3b), and both
Post-commit fix dispatches (Phase 2 initial fix and Step 5). Uncommitted
mode is exempt — it never commits, so there is nothing to gate; leave it as-is.
Resolving the verify command
The orchestrator resolves the command once, before the first fix dispatch of
the run, and passes it into each fix subagent prompt. Inline the config helper
block (verbatim, exactly as in Pre-flight Step 2 / shared/config.md) in the same
bash block, then:
VERIFY_CMD=$(read_solopreneur_config verify | jq -r '.cmd // empty' 2>/dev/null)
[ -z "$VERIFY_CMD" ] && echo "NO_VERIFIER" || echo "VERIFY_CMD=$VERIFY_CMD"
VERIFY_CMD empty (NO_VERIFIER) → skip the inner loop entirely; the fix
subagent commits exactly as it does today. Add one flag-style line to the final
report: "no objective verifier configured for this loop" (see Flags below).
Never invent a command.VERIFY_CMD set → pass it into every fix subagent this run, together with
the inner-loop instructions below.
Inner loop (inside the fix subagent)
The loop lives INSIDE the fix subagent's instructions — the subagent owns
edit → verify → iterate and only commits on a green verify. When VERIFY_CMD is
set, add this block to the fix subagent prompt (on top of that path's own
commit-message and hard-constraint instructions):
You have an objective verify command: <VERIFY_CMD>. Before you commit:
1. Apply your fix edits to the working tree.
2. Run <VERIFY_CMD> against the working tree. Do NOT commit first — lint /
typecheck / fast-unit are working-tree operations, so verify-before-commit
holds in EVERY mode, post-commit included (no "broken commit + fix commit"
sequence is ever created).
3. Pass (exit 0) → proceed to the commit + push step already specified for this
path (unchanged commit message).
4. Fail (non-zero) → do NOT commit. Feed yourself back only a TRUNCATED log — the
final failing assertion / first error line plus the tail, capped in size the
same way this file caps agy input at AGY_MAX_DIFF_BYTES — and retry the fix.
5. Cap: 3 verify attempts total. On the 3rd consecutive failure, do NOT commit or
push — return a structured halt result (reason `inner-verify-failed`,
`reason_class: invariant-violation`, the FULL verify log, your attempted-fix
summary) instead of committing.
Truncate every feedback log this way; the full log rides only in the halt
payload. Three stacked rounds of full logs would otherwise drown the signal.
Anti-gaming guard (before every commit)
The cheapest way to make a failing verify "pass" is to edit the tests or the
verify command itself. The subagent must check, before it commits: for every
test file or verify-definition file the fix diff touches, this round's findings
must explicitly reference that same file. If the diff touches a test file or the
verify definition that no finding called out → do not commit. Match per file —
a finding about one test file does not license editing a different, unmentioned
test file. In both modes the immediate action is the same — do not commit — with the
reason anti-gaming: fix touches test/verify definition unprompted; the level differs
only in what follows. Unattended halts the loop (its halt payload carries
reason_class: authority-boundary → the orchestrator blocks); attended flags it and
lets the present human adjudicate the suspected gaming. This is the one deliberate
unattended-halt / attended-flag split (a suspected gaming edit is cheap to adjudicate
live), an intentional exception to the usual halt→ask projection noted in the
Escalation taxonomy.
At size S (added by a later PR) there are no internal reviewers, so this guard is the only
defense against fix-to-pass gaming — it lands here, not in the escalation PR.
Halt / flag primitive
The level model that assigns halt / flag / note, the two-question rubric,
reason_class, the attended projection, and the findings-contradiction table all live
in Escalation taxonomy. This subsection is the
operational primitive the inner verify loop uses: how a halt is written and what the
orchestrator must do when one fires.
- halt — stop the loop and do not commit. Write a payload file — last round's
findings + the FULL verify log + attempted-fix summary + a
reason_class
(transient-dependency / invariant-violation / authority-boundary — retry
semantics in Escalation taxonomy) +
suggested next step —
under docs/loops/<run>/halts/ when running inside an autopilot run dir, else
the standalone fallback docs/loops/<date>_greenlight-<branch-slug>/halts/
(<date> = YYYY-MM-DD, <branch-slug> = current branch with every /
replaced by -, so a slashed name like feature/x stays one flat directory
instead of nesting). Reference the path in the final report. Unattended
semantics: report blocked and exit non-zero. Attended: surface the payload
path and ask the user how to proceed.
- Orchestrator obligation. Every fix dispatch below can return a halt
instead of committing. When it does, route straight to that mode's blocked
exit: do NOT run the post-dispatch push verification (a halt leaves
HEAD == origin/main, which would false-pass a HEAD != origin/main check),
do NOT resolve review threads, and do NOT start another round.
- flag — do NOT stop; keep looping, but record the event in a dedicated,
prominent Flags section of the final report (below) for a human to
adjudicate afterward.
Flags section (final report)
When any flag fired (no verifier configured, an attended anti-gaming catch, an
auto-classified size S without an explicit override, and the other flag sources in
Escalation taxonomy — a pushed-back P1, a fix
over 20 lines, a merge with no CI signal, findings contradictions ① and ②),
append a prominent section to whichever mode's final report runs:
## Flags (human review suggested)
- <flag reason 1>
- <flag reason 2>
Omit the section entirely when nothing flagged.
Worst-case work bound
The inner loop is a newly multiplied retry layer, so make the nesting explicit.
The wave ×2 wraps, per attempt, one implement pass followed by the greenlight
loop; within an attempt those two stages run in sequence, so their counts add,
they do not multiply. Autopilot's Step 3 self-fix ×3 runs during implement,
then greenlight's outer review rounds — now per size (S 3 / M 5 / L 10; see
Sizing) — each wrap inner verify ×3. At the L
ceiling that is 10 × 3 = 30 fix attempts, so a single PR-mode L PR under autopilot
tops out near 2 × (3 + 10 × 3) = 66 fix attempts; a default M PR is
2 × (3 + 5 × 3) = 36 and an S PR is 2 × (3 + 3 × 3) = 24 — the self-fix
stage is additive with the review rounds, not a multiplier on them. The inner loop
multiplies fix work per round; a repo whose verify command is slow pays for it
here — which is why verify must stay fast and E2E stays in CI (see config
verify key).
Escalation taxonomy (halt / flag / note)
Every escalation in this skill resolves to one of three levels. The model is
unattended-first (greenlight runs unattended under autopilot / todos-babysit), with
an attended projection for manual runs. The operational
mechanics — how a halt payload is written, the orchestrator's obligation on a halt —
live in Halt / flag primitive; this section is the model that
assigns a level.
Two-question rubric
Assign a level by asking, in order:
- Can the loop still continue? A mechanical block — every reviewer tool is down,
the environment is broken, the round budget is spent, an invariant is violated — is
a halt. Not negotiable.
- Is this decision mine to make? Three checks: reversibility (can a wrong call
be undone cheaply?), scope (is it inside the spec / size authorization?), and
adjudicability (is there a test or spec that mechanically decides right from
wrong?). A decision that is expensive-if-wrong, or that cannot be mechanically
adjudicated → escalate to a human (flag, or halt when it also blocks the
loop). Everything else → act autonomously and leave a trace (note).
The three levels
| Level | Behavior (unattended) | Examples |
|---|
| halt | Stop, write the payload, report — blocked, exit non-zero. | External reviewers all down; a broken invariant; a fix that must touch a dangerous path outside the size authorization; inner verify fails 3×. |
| flag | Keep looping; record the decision in the report's prominent Flags section for a human to adjudicate afterward. | A pushed-back P1; a fix over 20 lines; a loop that ran with no verifier configured; a merge with no CI signal; an auto-classified size S; findings contradictions ① and ② (below). |
| note | Normal stats — no special surfacing. | fixed / pushed-back counts; out-of-contract (③ note-tier) and style-only (⑤) push-backs. |
The flag middle tier is what makes unattended running safe: without it, an
unattended run could only choose between halting on everything and running fully
autonomously with no human ever told. Keep the Flags section signal-dense —
correctness-flavored events only; style noise stays at note (see contradiction ⑤).
reason_class (halt retry semantics)
Every halt payload carries a reason_class so a downstream orchestrator can route
retry-vs-blocked without re-deriving intent:
reason_class | Meaning | Retry semantics | Fires when |
|---|
transient-dependency | A dependency is down but may recover. | Retryable — orchestrator waits and retries. | External reviewers all exhausted (unattended fallback). |
invariant-violation | A hard stop the loop cannot resolve itself — a broken correctness / state invariant, or the round budget spent without convergence. | Do not retry — orchestrator marks blocked. | Inner verify fails 3×; a post-commit invariant violation (TIP ≠ HEAD, origin/main unreachable, BASE unreachable, push-verification mismatch, branch changed mid-loop); the round budget spent (max SIZE_MAX_ROUNDS reached with findings still unresolved). |
authority-boundary | The next step needs authority the run does not have — refuse. | Do not retry — a human must intervene. | A fix would touch a dangerous path outside the size authorization (contradiction ③); the anti-gaming guard's unattended halt (a refusal to commit a suspected gaming edit). |
reason_class governs only the unattended halt's retry routing; it does not
dictate the attended projection (that is set by the level — see
Attended projection). The two are independent axes: the
anti-gaming guard writes an authority-boundary payload when it halts unattended, yet
its attended level is deliberately flag, not the usual halt→ask (the one documented
exception — see Anti-gaming guard).
The autopilot orchestrator consumes this from the halt payload greenlight references in
its report — see ../autopilot/references/orchestrator.md (failure table).
Attended projection
The three levels are unattended-first, but greenlight is also run manually, and the
flow is full of "ask the user" branches. Attended runs project the levels — with no
regression to existing interactive behavior:
| Level | Unattended | Attended |
|---|
| halt | blocked, exit non-zero | ask the user and wait — the loop is blocked until they decide (not a hard exit): the reviewer-exhaustion wizard, the invariant stops |
| flag | record in the Flags section | surface inline during the run (and still record it in the Flags section) — a decision-point flag (a contradiction, a >20-line fix) keeps its existing user prompt so the human can weigh in, but, unlike a halt, the run is never hard-blocked |
| note | stats | stats |
The distinction is not "prompt vs. no prompt" — it is whether the loop can proceed. A
halt cannot continue without the answer (attended blocks on it; unattended exits);
a flag always has a defined next move (unattended records + proceeds per the level /
table), and attended merely surfaces it — keeping any pre-existing prompt — so the human
can redirect. So every existing "ask the user" behavior maps on with no regression: the
reviewer-exhaustion wizard is a halt (ask and wait); an ambiguous consolidation and the
">20 lines discuss first" note are decision-point flags (surfaced with their prompt
intact).
Findings-contradiction handling table
Reviewers can contradict each other (or the spec), and the verification gate's skeptics
validate each finding independently — they never cross-compare, so both sides of a
contradiction can survive. Conservative side = leave the current state untouched
(no-action), never guess one side and execute it. Unattended disposition:
| # | Contradiction | Disposition (unattended) |
|---|
| ① | Same-round opposite fixes for the same code (e.g. ponytail says delete a defensive check, specialist says add a null check) | Apply neither — no-action is the only move that negates neither side and keeps the state that already passed prior rounds → record both as pushed-back(contradiction) + flag. |
| ② | Cross-round flip-flop — a new finding would revert a previously accepted fix (e.g. round 1 extract a helper, round 3 inline it back) | Maintain a per-loop accepted-fixes journal and include it in the fix subagent's prompt; a mutually-exclusive new finding is not executed → pushed-back(flip-flop) + flag. Conservative side = the already-accepted fix (no thrashing). |
| ③ | Finding conflicts with the spec / size authorization — mechanically adjudicable, the spec is the judge | The spec wins → pushed-back(out-of-contract) + note. If the reviewer's reasoning is correctness-grade (it implies the spec itself is wrong) → escalate to flag. If the fix would touch a dangerous path → halt (authority-boundary). Standalone /greenlight with no spec: this type degenerates to ①. |
| ④ | Reviewer P1 vs fix-subagent false-positive push-back (reviewer vs fix agent, not two reviewers) | Push back the P1 → flag (pre-existing decision; listed for completeness). |
| ⑤ | Style-only contradiction — the low-stakes version of ① (e.g. one wants more comments, one finds them noisy) | No action + note — never flag; every style contradiction flagged would drown the Flags section, which stays correctness-flavored. |
Attended runs keep asking — ①② are decision-point flags and ③'s dangerous-path
case is a halt; either way the attended projection surfaces the
existing user prompt (the flag inline, the halt blocking). One-line summary:
mechanically adjudicable → let the spec judge;
otherwise leave the state untouched — flag the correctness-grade contradictions, note
the style ones; the only halt is a fix that crosses the authorization boundary.
Where the existing sites map
The taxonomy re-labels existing behavior; only two behaviors change (contradictions no
longer ask the user in unattended runs — the table above; and the orchestrator now
defers its round bound to greenlight — orchestrator.md). The scattered rules map as:
- Phase 1 all internal reviewers fail → unchanged: skip Phase 1 + 2 and proceed
to Phase 3 (NOT a halt — internal review is optional; external review still runs).
See Phase 1 "All fail".
- External fallback exhausted (all reviewers down) → halt,
reason_class: transient-dependency — see Fallback Logic.
- Post-commit invariant violations → halt,
reason_class: invariant-violation —
the invariant guards in Post-commit parsing
and the per-round re-checks.
- Fix over 20 lines → flag (a decision-point flag: attended surfaces it inline
with the existing "discuss first" prompt; unattended records it and proceeds).
- Contradictory findings → the
table above.
- Inner verify 3× fail → halt,
reason_class: invariant-violation — see
Inner verify loop.
- Anti-gaming catch → the deliberate unattended-halt / attended-flag split from
the verifier PR: "do not commit" holds in both modes; unattended halts the loop (payload
reason_class: authority-boundary), attended flags it for the present human to
adjudicate. See Anti-gaming guard.
Sizing (S/M/L risk profile)
Not every PR needs the full review weight — a one-line docs fix and a payment-path
refactor should not run the same five reviewers for ten rounds. Greenlight
classifies each run by risk into S / M / L and gates the expensive
phases on the result. PR mode and Post-commit mode are sized; Uncommitted mode is
exempt — it is a local, no-commit, interactive flow, keeps its own fixed loop, and
never computes a size.
Mechanical cascade (bash-computable, no LLM judgment)
Size is computed from the real diff — its file list and line counts — by a
deterministic cascade. No model judgment enters the classification. The asymmetry is
deliberate: L is OR (any one danger signal escalates) while S is AND (every
file must be harmless to de-escalate). When the signals disagree, the cascade
escalates — L is checked first and wins over S.
- L — any of these (OR):
- a touched path matches
migrations/, auth / payment / crypto code,
.github/workflows/, a Dockerfile / container / infra config (k8s, Helm,
Terraform), or a dependency manifest with a substantive change — package.json,
requirements*.txt, Pipfile, pyproject.toml, go.mod, build.gradle(.kts),
pom.xml, Podfile, and the like (lockfiles excluded — they are generated, not
authored);
- OR the diff exceeds ~400 changed lines, excluding lockfiles and generated files.
- S — all touched files fall inside the whitelist (AND):
docs/**
(excluding docs/loops/** — that is live orchestration config the autopilot
reads and executes, not prose), todos/**, the repo-root README.md only
(plugin READMEs carry install commands and stay out), LICENSE, .gitignore.
Never a global *.md glob — in a skill-type repo the product is markdown, so a
SKILL.md change must classify M, not S.
- Otherwise → M. Any uncertainty in classification defaults to M.
Config files are deliberately not in the S whitelist: a config error is a silent
runtime behavior change, so config edits stay at M. (The former "cross-module
boundary" trigger is deliberately dropped — it is not mechanically computable, so it
is not part of this cascade.)

Size override & freshness
A caller may pass a size=s|m|l token (see Arguments). It is
advisory and upward-only: the size computed from the real diff is authoritative,
and the effective size is max(passed, computed) on the order S < M < L. A
token never lowers the computed size. This makes scope creep upgrade-only and defeats
"planned S, grew into M" gaming — a PR scoped size=s that actually touches auth is
still reviewed as L.

When the cascade auto-classifies S with no explicit override, add one flag-style
line — "auto-sized S — verify" — to the final report (see the Flags section under
Inner verify loop).
Profile — what each size gates
Reviewer selection is expressed in the Reviewer Registry
vocabulary; no bot login is hardcoded here.
| Effective size | Phase 1 internal | Verification gate | Phase 3 external loop (SIZE_MAX_ROUNDS) |
|---|
| S | skip | skip | Phase 3 only, one external reviewer — PR mode via its registry-driven current_reviewer + fallback_order (default codex-bot, preferring codex); Post-commit via the single preferred available CLI (Codex CLI, else agy) instead of its usual parallel pair — loop to clean, max 3 rounds |
| M (default) | 2 reviewers — /specialist-review + ponytail:ponytail-review (rows 4–5 of the Phase 1 table) | skip | standard registry loop, max 5 rounds |
| L | all 5 reviewers | ON (when the Workflow tool is available) | full registry fallback chain, max 10 rounds |
- S behaves like
external_only with a 3-round cap: Phase 1 and Phase 2 are
skipped and the run goes straight to Phase 3, still looping to a clean result
(S is not a single-pass mode — the cost cap is the round bound, not one shot).
Because S is external-only, its one reviewer must actually be available: when no
explicit reviewer arg and no fallback_order are configured, resolve the starting
current_reviewer to the first available external reviewer, preferring codex —
codex-cli when its pre-flight CLI gate passed, else a detected active-bot (prefer
codex-bot), else the codex-bot default with the existing not-detected warning.
This reuses the pre-flight CLI gate and activity detection (registry vocabulary, no
hardcoded logins), so an unattended S run uses the authed CLI instead of failing on
an absent bot. Post-commit S likewise runs a single preferred available CLI (Codex
CLI, else agy) rather than the usual codex-CLI + agy pair, shedding the doubled cost.
- The verification gate already runs only when the
Workflow tool is present;
sizing adds a second condition — it runs only at size L (S and M skip it even
when Workflow is available).
- The inner verify loop is not size-differentiated: every size runs the same
single
verify command (see Inner verify loop).
Sizing dials review weight, not the objective verifier.
SIZE_MAX_ROUNDS (3 / 5 / 10 for S / M / L) is the Phase 3 loop bound in
both PR mode and Post-commit mode.
Pre-flight Checks
Step 1: Mode detection
Determine whether to run PR mode or Uncommitted mode based on current repo state:
CURRENT_BRANCH=$(git branch --show-current)
HAS_UNCOMMITTED=$(git status --porcelain | grep -q . && echo yes || echo no)
if gh pr view --json number,state >/tmp/gl-pr.json 2>/dev/null; then
PR_EXISTS=yes
PR_STATE=$(jq -r .state /tmp/gl-pr.json)
else
PR_EXISTS=no
PR_STATE=none
fi
HAS_POST_COMMIT_ARG=$(echo "$RAW_ARGS" | grep -iq "post-commit" && echo true || echo false)
echo "BRANCH=$CURRENT_BRANCH UNCOMMITTED=$HAS_UNCOMMITTED PR=$PR_EXISTS/$PR_STATE POST_COMMIT_ARG=$HAS_POST_COMMIT_ARG"
Override:
- If
HAS_POST_COMMIT_ARG=true AND CURRENT_BRANCH != main, stop with a clear
error: post-commit mode is only valid on main (Phase 3 hardcodes main /
origin/main checks and would crash on a feature branch). Tell the user to
either switch to main or use PR mode (/greenlight on the feature branch with
an open PR).
- If
HAS_POST_COMMIT_ARG=true AND CURRENT_BRANCH == main AND HAS_UNCOMMITTED=no,
set MODE=post-commit immediately and skip the rest of this table.
- If
HAS_POST_COMMIT_ARG=true AND CURRENT_BRANCH == main AND HAS_UNCOMMITTED=yes,
stop and ask the user how to proceed before continuing — options: (A) stash
uncommitted changes and proceed with post-commit review, (B) abort, (C) proceed
but only stage explicit files for the fix commits. Do NOT auto-include uncommitted
WIP in the post-commit fix commits — they would be pushed to origin/main together
with the review fix.
Mode table:
| Branch | Uncommitted | PR (open) | MODE | Action |
|---|
main | yes | no | uncommitted | Enter Uncommitted mode (skip all phases below) |
main | yes | yes (open) | ask | Unusual — ask user: "On main with uncommitted + open PR. Run uncommitted mode on working tree, or abort?" |
main | no | no, AND HAS_POST_COMMIT_ARG=true | post-commit | Resolve commit range from the SHA argument; enter Post-commit mode |
main | no | — | stop | Nothing to review on main; tell user |
| feature / worktree | — | yes (open) | pr | Continue with Pre-flight Step 2 below (default flow) |
| feature / worktree | yes | no | ask | Ambiguous — ask user: "On feature branch with uncommitted and no PR yet. (A) Commit and push first to create PR, then review (B) Run uncommitted mode on working tree (C) Abort" |
| feature / worktree | no | no | stop | No PR + no changes; tell user to commit or create PR first |
The post-commit row is more specific than the stop row — match it first; otherwise fall through to stop.
If MODE=uncommitted, skip Steps 2-5 below and Argument Parsing; jump directly to Uncommitted Mode.
If MODE=post-commit, skip PR-mode pre-flight Step 2 below; do Argument Parsing (post-commit subsection) to resolve RANGE_SPEC, then jump to Post-commit Mode.
Step 2: PR mode pre-flight (MODE=pr only)
-
PR info already recorded in Step 1 (/tmp/gl-pr.json). Confirm state is OPEN; if not, stop.
-
Confirm working directory is clean:
git status --porcelain
If uncommitted changes exist, ask the user whether to commit first.
-
Record the PR number and repo owner/name (from gh repo view --json owner,name).

Argument Parsing
⏭️ Skip this section entirely if MODE=uncommitted — jump to Uncommitted Mode.
Post-commit mode parsing (MODE=post-commit only)
raw_args = args ?? ""
spec = raw_args after "post-commit" keyword (trimmed) — empty if keyword absent
if spec is empty:
→ ask user to provide a SHA or range (e.g., "/greenlight post-commit <SHA>")
elif spec matches a single SHA (verify with `git rev-parse --verify <SHA>^{commit}`):
RANGE_SPEC = single, BASE_SHA = "<SHA>^", TIP_SHA = "<SHA>"
elif spec matches "<FROM>..<TO>" (verify both SHAs exist):
# Follow standard git revision-range semantics: FROM is exclusive, TO is inclusive.
# `git diff <FROM>..<TO>` shows changes between FROM's tree and TO's tree, which
# equals the cumulative effect of commits (FROM, TO]. Do NOT use "<FROM>^" — that
# would include FROM itself, contradicting the `..` convention the user typed.
RANGE_SPEC = range, BASE_SHA = "<FROM>", TIP_SHA = "<TO>"
else:
→ tell user spec is invalid, stop
# Invariant: TIP_SHA must equal HEAD.
# Reviewing a historical range (TIP_SHA < HEAD) would let downstream tools leak
# past the user's intended tip: `codex review --base BASE` reviews BASE..HEAD
# (not BASE..TIP), and the per-round `TIP_SHA = HEAD` advance in Phase 3 would
# sweep in unrelated intermediate commits on subsequent rounds. Rather than
# silently expanding scope, reject historical ranges up front.
if `git rev-parse <TIP_SHA>` != `git rev-parse HEAD`:
→ stop with: "Post-commit mode requires TIP_SHA == HEAD. Got TIP=<short-SHA>,
HEAD=<short-SHA>. For historical-only review of a single commit, invoke per-commit
instead: `codex review --commit <SHA>`."
# Invariant: origin/main must be reachable from HEAD (local main not behind origin).
# Post-commit mode's contract is "review committed work" — push state is not part
# of the contract. Local-only commits (HEAD ahead of origin/main) are allowed: the
# review loop's fix-on-top push will publish them together with the fix commits,
# which is the expected "review then land" flow.
# What we MUST prevent is a stale local main (HEAD behind origin/main): the
# per-round fix-on-top push would be rejected as non-fast-forward, breaking the loop.
# `git merge-base --is-ancestor origin/main HEAD` returns true iff origin/main is
# reachable from HEAD — which holds when HEAD == origin/main OR HEAD is ahead of
# origin/main, but fails when HEAD is behind. Exactly the condition we want.
git fetch origin main
if ! git merge-base --is-ancestor origin/main HEAD:
→ stop with: "Post-commit mode requires local main to not be behind origin/main
(origin/main must be reachable from HEAD). Got HEAD=<short-SHA>,
origin/main=<short-SHA>. Pull/rebase first, then re-invoke."
# Invariant: BASE_SHA must be reachable from origin/main.
# When HEAD is ahead of origin/main, the fix-on-top push at end-of-loop will
# publish everything in (origin/main, HEAD]. If RANGE_SPEC starts past
# origin/main (BASE_SHA itself local-only), commits in (origin/main, BASE_SHA]
# would be pushed without ever being reviewed. Require BASE_SHA to be on or
# before origin/main so the reviewed range (BASE_SHA, HEAD] covers every
# local-only commit on the branch.
if ! git merge-base --is-ancestor <BASE_SHA> origin/main:
→ stop with: "BASE_SHA must be reachable from origin/main — the reviewed
range must cover all local-only commits, otherwise unreviewed commits
would be pushed by the fix-on-top loop. Got BASE=<short-SHA>, which is
itself local-only. Either widen the range to start at or before
origin/main, or push existing local commits first."
These invariant guards — and the per-round re-checks in Phase 3 (Step 1's branch /
BASE / TIP checks and the push-verification gates) — are halt /
invariant-violation in the
Escalation taxonomy: a hard stop the
orchestrator must not retry (attended: surface the error and ask the user).
After resolving, jump to Post-commit Mode — skip the PR mode parsing block below.
PR mode parsing (MODE=pr only)
# Parse external mode and reviewer from args
# e.g.: "/greenlight external gemini" → external_only=true, reviewer="gemini"
# e.g.: "/greenlight codex cli" → external_only=false, reviewer="codex cli"
# e.g.: "/greenlight external" → external_only=true, reviewer="codex bot" (default)
raw_args = args ?? ""
# Match WHOLE whitespace-delimited tokens case-insensitively — never a substring.
# Substring matching would let "unattendedness" enable unattended mode and would
# corrupt a reviewer name that happens to contain "external".
tokens = raw_args split on whitespace
external_only = tokens has a token equal (case-insensitive) to "external"
unattended = tokens has a token equal (case-insensitive) to "unattended"
size_arg = value of a token matching (case-insensitive) "size=<s|m|l>", else ""
(a malformed size=… value is ignored — treated as "")
reviewer_args = tokens with the "external"/"unattended"/"size=…" tokens dropped, rejoined + trimmed
current_reviewer = reviewer_args non-empty ? reviewer_args : "codex bot"
# `unattended` (set by todos-babysit auto mode / autopilot dispatch): every
# "ask the user" branch in Reviewer selection / Fallback Logic below becomes
# "log the reason and exit non-zero" — never block on input.
# Codex CLI availability gate: if user specified codex cli but CLI unavailable, fall back
if current_reviewer == "codex cli" and pre-flight detected CLI not installed or not authenticated:
→ notify user:
- not installed: "Codex CLI not installed, switching to Codex GitHub bot. To install: npm install -g @openai/codex && codex login"
- not authenticated: "Codex CLI not authenticated, switching to Codex GitHub bot. Run: !codex login"
→ current_reviewer = "codex bot"
# Effective size (see Sizing). Run the cascade over the PR diff and take the
# upward max of the passed token and the computed size:
# export SIZE_ARG="<size_arg>"; DIFF_RANGE="main...HEAD"
# → run the "Mechanical cascade" + "Size override & freshness" snippets
# → EFFECTIVE_SIZE ∈ {S,M,L}, SIZE_MAX_ROUNDS ∈ {3,5,10}
# If COMPUTED_SIZE=S and size_arg is empty, record the "auto-sized S — verify" flag.
If external_only == true OR EFFECTIVE_SIZE == S, skip Phase 1 and Phase 2, jump directly to Phase 3 (size S reviews externally only — see Sizing).
Uncommitted Mode
Only runs when MODE=uncommitted from Pre-flight Step 1. PR mode skips this section entirely.
Codex CLI --uncommitted review loop. Fixes in-place, does NOT commit. User reviews and commits manually afterwards.
Loop
round = 0
LOOP (max 10 rounds):
round += 1
1. Verify still on main with uncommitted changes:
```bash
git branch --show-current # must be main
git status --porcelain # must be non-empty
```
If either changed (e.g., user switched branch or committed mid-loop) → stop and tell user.
2. Run codex CLI:
```bash
codex review --uncommitted -c 'model_reasoning_effort="high"' --enable web_search_cached 2>&1
```
Capture full stdout/stderr. Timeout: 5 min.
3. Parse output:
- No `[P*]` tags (only summary paragraphs like "looks good" / "no issues") → **clean pass, exit loop**
- Has `[P*]` tags → extract findings (file, line, priority, description, suggested fix)
- Stderr contains "usage limit" / "rate limit" / non-zero exit → stop, tell user codex CLI unavailable, preserve working tree
4. Dispatch fix subagent — see Step 4 below.
5. After subagent returns, verify working tree still has uncommitted changes (subagent might have accidentally committed).
If working tree is clean but commits were added → stop and tell user (violates no-commit invariant).
6. Back to step 1 (next round). Pass prior-round findings to next subagent for push-back awareness.
End: max 10 rounds reached → stop and report to user.
Step 4: Fix subagent (per round)
Dispatch subagent with these explicit instructions. Use Agent tool, general-purpose type.
Agent(
description: "Fix codex uncommitted review findings (round N)",
prompt: <see below>
)
Prompt must contain:
-
Context: "You are in uncommitted mode. All changes live in the working tree on the main branch. Your job is to address codex review findings by editing files directly."
-
Findings list (full stdout from codex, or parsed list with file + line + priority + description + suggested fix).
-
Prior push-backs (if round > 1): list of findings from earlier rounds that were pushed back with reasoning. Subagent should reconsider before pushing back again.
-
Evaluation framework: "Invoke superpowers:receiving-code-review skill first to load the review-receiving mindset. If unavailable, evaluate each finding: fix genuine issues, push back on false positives with solid technical reasoning."
-
Hard constraints:
- Do NOT run
git commit, git push, git add && commit, or any commit operation.
- Do NOT create branches, worktrees, or PRs.
- Edit source files directly. Leave all changes uncommitted.
- If you want to push back on a finding, write reasoning in your final report — do not add code comments explaining the push-back (keeps the diff clean).
-
Return format: report what was fixed (file + line + fix summary) and what was pushed back (finding + reasoning).
Exit Conditions
- Clean pass: codex stdout has no
[P*] tags → report rounds run, items fixed, items pushed back.
- Push-back exit: all findings this round were already pushed back in prior rounds with the same reasoning → report and exit.
- Max 10 rounds: stop and report last round's findings; let user decide.
- Aborted invariants: branch changed / commits appeared / codex CLI unavailable → stop with specific reason.
Final report (on any exit)
Uncommitted review loop complete.
- Exit reason: <clean pass / push-back / max rounds / aborted>
- Rounds run: <N>
- Items fixed: <M>
- Items pushed back: <K>
- Working tree: has uncommitted changes (run `git diff` to review, then commit manually)
Do not offer to commit or push. User's CLAUDE.md rule on product repo main branch: wait for explicit user instruction.
Post-commit Mode
Only runs when MODE=post-commit from Pre-flight Step 1, which requires the
explicit /greenlight post-commit <SHA> argument (no auto-detect). PR mode and
Uncommitted mode skip this section entirely.
Reviews committed work on main (pushed or local-only) when no open PR exists.
Runs Phase 1 internal subagents + Codex CLI + agy in parallel. Skips
PR-bound reviewers (Codex GitHub bot, Gemini Code Assist bot, CodeRabbit) since
they require an open PR. agy is the Gemini-family CLI reviewer here — pinning it
to a Gemini model keeps model diversity against the Claude main loop and the
GPT-family Codex.
Fixes are committed as new commits on top — no git commit --amend. Reasons:
keeps the loop logic uniform whether or not the original commits were already
pushed (amend would require force-push for pushed commits, violating the "no
rewriting shared history" rule); preserves the original commit boundary; lets
each review round produce a clearly attributable fix commit.
Convention: the bash snippets in this section are illustrative pseudo-code,
not literal runnable scripts. The orchestrating agent translates them before
execution: substitute <PLACEHOLDERS> with concrete values, replace prose
directives like stop with: "..." with valid bash (e.g. echo "..."; exit 1),
and ensure heredoc terminators (EOF) start at column 1 (or use <<- with tabs).
Snippets prioritize readability over runnability.
Range resolution (recap)
RANGE_SPEC, BASE_SHA, and TIP_SHA were resolved during Argument Parsing. The
diff command depends on shape:
| RANGE_SPEC | Diff command |
|---|
single (TIP_SHA) | git show <TIP_SHA> |
range (BASE_SHA..TIP_SHA) | git log -p <BASE_SHA>..<TIP_SHA> (preserves per-commit subject/message — preferred) or git diff <BASE_SHA>..<TIP_SHA> (unified diff only, when reviewer just wants the cumulative changes) |
Range semantics: BASE_SHA is exclusive and TIP_SHA is inclusive — i.e. the
review covers commits (BASE_SHA, TIP_SHA]. This matches standard git .. convention.
Invariant: TIP_SHA == HEAD. Enforced during Argument Parsing — historical ranges
(TIP < HEAD) are rejected with a clear error. This keeps codex review --base BASE
(which reviews to current HEAD) equivalent to BASE..TIP_SHA, and prevents the
per-round TIP_SHA = HEAD advance from sweeping in unrelated intermediate commits.
Resolve the verify command (once, before any fix dispatch)
Post-commit mode skips PR-mode Pre-flight Step 2, so VERIFY_CMD is not resolved
by that path. Resolve it here instead — once, before Phase 2 (the first fix
dispatch) — exactly as Resolving the verify command
prescribes: inline the solopreneur_repo_key + read_solopreneur_config helpers
(verbatim from Pre-flight Step 2), then in the same bash block:
VERIFY_CMD=$(read_solopreneur_config verify | jq -r '.cmd // empty' 2>/dev/null)
[ -z "$VERIFY_CMD" ] && echo "NO_VERIFIER" || echo "VERIFY_CMD=$VERIFY_CMD"
Without this step both post-commit fix dispatches (Phase 2 and Phase 3 Step 5)
would read an unset VERIFY_CMD and silently skip the inner verify loop — the
mode would never gate a fix, defeating this PR's purpose. On NO_VERIFIER, skip
the inner loop in both dispatches and add the "no objective verifier configured
for this loop" flag to the final report.
Resolve the effective size (once, before Phase 1)
Post-commit mode is sized too (only Uncommitted mode is exempt). Compute it once,
before Phase 1, exactly as Sizing prescribes — run the
cascade with DIFF_RANGE set to the resolved review range and no size= token
(post-commit ignores non-post-commit args, so SIZE_ARG is empty and
EFFECTIVE_SIZE = COMPUTED_SIZE):
if [ "$RANGE_SPEC" = single ]; then DIFF_RANGE="${TIP_SHA}^..${TIP_SHA}"; else DIFF_RANGE="${BASE_SHA}..${TIP_SHA}"; fi
SIZE_ARG=""
EFFECTIVE_SIZE then gates Phase 1 reviewer selection, the verification gate, and
the Phase 3 SIZE_MAX_ROUNDS loop bound below — the same profile PR mode uses.
Because there is no override token, an S here is always auto-classified, so it
records the "auto-sized S — verify" flag.
Phase 1: Internal Review (post-commit variant)
Same as PR mode Phase 1, including the EFFECTIVE_SIZE gate
(Sizing): at S skip Phase 1 (and Phase 2) entirely
and go straight to Phase 3; at M run only /specialist-review +
ponytail:ponytail-review; at L run all 5. Dispatch the selected subagents in
parallel, report-only — but the diff range is RANGE_SPEC instead of main...HEAD.
Each subagent prompt must include the actual diff content (output of the diff
command above), not the raw shell expression. Subagents are still report-only.
After all subagents return, consolidate findings (merge + dedupe) → PHASE1_FINDINGS
(at size S there are none — skip to Phase 3).
Verification gate (optional). At effective size L with the Workflow tool
available (S and M skip it), run the adversarial verification gate on
PHASE1_FINDINGS before Phase 2 — see Verification gate and
references/adversarial-verify.md.
Pass PHASE1_FINDINGS as findings and the resolved range diff command from the
Range resolution table as diff_cmd. Replace
PHASE1_FINDINGS with the confirmed (survivor) list; record rejected
findings as pushed back. If every finding is rejected, PHASE1_FINDINGS is now
empty — follow the existing empty path (skip Phase 2, go to Phase 3). Tool
unavailable → skip the gate; PHASE1_FINDINGS is unchanged.
Phase 2: Initial fix (Phase 1 findings only)
If PHASE1_FINDINGS is non-empty, dispatch a fix subagent with the same evaluation
framework as Uncommitted Mode (superpowers:receiving-code-review first), but with
post-commit hard constraints:
- Edit source files directly.
- Inner verify loop (when
VERIFY_CMD is set): after editing, run VERIFY_CMD
against the working tree before the commit below; commit only on a green
verify; on the 3rd failure return a structured halt (no commit/push). Include the
anti-gaming guard. See Inner verify loop.
- After edits, run
git add + git commit + git push. Commit message:
fix: post-commit review fixes (Phase 1) — <summary>.
- Do NOT use
git commit --amend. Always fix as new commits on top — see
rationale at the top of Post-commit Mode.
- Do NOT create a new PR or branch.
Halt check (before the push verification below). If the fix subagent returned
a structured halt (inner-verify failure or anti-gaming catch) it made no commit —
stop at the blocked exit and reference the halts/ payload. Do NOT fall through to
the push verification below: a halt leaves HEAD == origin/main, which would
false-pass its HEAD != origin/main check and mask the failure.
After push, verify the push actually landed on origin/main before advancing
TIP_SHA — same hard gate as Phase 3 Step 6. If the fix subagent's push was
rejected or skipped, Phase 3 would otherwise enter the loop reviewing local-only
commits:
git fetch origin main
LOCAL_HEAD=$(git rev-parse HEAD)
REMOTE_HEAD=$(git rev-parse origin/main)
if [ "$LOCAL_HEAD" != "$REMOTE_HEAD" ]; then
stop with: "Phase 2 push verification failed — HEAD ($LOCAL_HEAD) does not
match origin/main ($REMOTE_HEAD). The fix subagent's push was rejected or
skipped. Investigate before continuing."
fi
Push confirmed. Advance TIP_SHA = HEAD. If RANGE_SPEC = single, also set
RANGE_SPEC = range (keep BASE_SHA unchanged) so subsequent rounds review the
full cumulative range (BASE_SHA..HEAD) — not just the latest fix commit, which
would forget the original commit under review.
If PHASE1_FINDINGS is empty, skip Phase 2 and proceed straight to Phase 3.
Phase 3: External CLI loop
Codex CLI and agy run in parallel each round; results are merged + deduped;
fixes commit on top; repeat.
agy availability gate (mirrors the Codex CLI gate). agy has no login status
subcommand, so probe headless output once before the loop — one trivial call
proves installed AND authenticated AND that non-TTY stdout is not being dropped:
AGY_AVAILABLE=false
if command -v agy &>/dev/null; then
AGY_PROBE=$(agy --print "reply with the single word READY" 2>&1)
if printf '%s' "$AGY_PROBE" | grep -q "READY" \
&& ! printf '%s' "$AGY_PROBE" | grep -qiE "https?://[^ ]*(auth|login|oauth|accounts\.google)"; then
AGY_AVAILABLE=true
fi
fi
If AGY_AVAILABLE=false, skip the agy dispatch each round and run Codex CLI only.
If Codex CLI is also unavailable, the existing "both CLIs fail → stop" path fires.
round = 0
LOOP (max SIZE_MAX_ROUNDS rounds — S 3 / M 5 / L 10; see Sizing):
round += 1
1. Verify still on main, BASE_SHA is reachable from HEAD, and TIP_SHA == HEAD:
```bash
git branch --show-current # must be main
git merge-base --is-ancestor <BASE_SHA> HEAD || echo "BASE not reachable"
[ "$(git rev-parse <TIP_SHA>)" = "$(git rev-parse HEAD)" ] || echo "TIP != HEAD"
```
If branch changed, BASE unreachable, or TIP != HEAD → stop and tell user.
(TIP == HEAD is the invariant set during Argument Parsing and re-asserted
each round after the fix-commit advance — see Step 6.)
2. Dispatch the external reviewers. **At `EFFECTIVE_SIZE` M or L**, run Codex CLI
and agy (when `AGY_AVAILABLE=true`) **in parallel** (parallel Bash tool calls,
or `&`-backgrounded shell — never sequential). **At `EFFECTIVE_SIZE` S**, run
only the **single preferred available** external reviewer — Codex CLI when
available, else agy — never both: the S profile is one reviewer (see
[Sizing](#sizing-sml-risk-profile)), and the parallel pair is exactly the
doubled cost S removes. The steps below are written for the full pair; at S,
skip whichever reviewer is not the chosen one.
**Codex CLI:**
```bash
# Single commit:
codex review --commit <TIP_SHA> -c 'model_reasoning_effort="high"' 2>&1
# Range (BASE_SHA..TIP_SHA):
codex review --base <BASE_SHA> -c 'model_reasoning_effort="high"' 2>&1
```
Capture stdout. Parse `[P*]` tags.
> Under the `TIP_SHA == HEAD` invariant, `codex review --base <BASE_SHA>` is
> equivalent to reviewing `<BASE_SHA>..<TIP_SHA>`. (Historical ranges where
> `<TIP_SHA>` ≠ HEAD are rejected during Argument Parsing.)
**agy (Gemini-family CLI):**
```bash
# Capture the diff first — see "Range resolution" table above for the exact
# diff command to use. Use `git log -p <BASE>..<TIP>` form (or `git show` for
# single) so per-commit context (subject, author, message) is preserved.
# Substitute <RANGE_SPEC>, <TIP_SHA>, <BASE_SHA> with their resolved values
# from the Range resolution step before running.
if [ "<RANGE_SPEC>" = "single" ]; then
DIFF_CONTENT=$(git show "<TIP_SHA>")
else
DIFF_CONTENT=$(git log -p "<BASE_SHA>..<TIP_SHA>")
fi
# agy `--print` (headless) does NOT read stdin — the whole diff rides in a
# single --print argument. That exposes two failure modes, guarded below.
#
# (1) argv size: argv+env is bounded by SC_ARG_MAX, so a large diff can fail
# agy before it starts. Codex CLI in this same loop reviews via `--base`
# with no such limit, so on an oversized diff degrade only the agy branch.
AGY_MAX_DIFF_BYTES=100000 # conservative; well under a 256KB+ ARG_MAX with env headroom
if [ "$(printf '%s' "$DIFF_CONTENT" | wc -c)" -gt "$AGY_MAX_DIFF_BYTES" ]; then
echo "diff too large for agy argv (> $AGY_MAX_DIFF_BYTES B) — Codex CLI only this round"

# echoed diff line pass. Empty OR missing/misplaced marker → agy failure,
# degrade to Codex CLI only this round.
AGY_LAST=$(printf '%s' "$AGY_OUT" | grep -v '^[[:space:]]*$' | tail -n1 | tr -d '[:space:]')
if [ -z "$AGY_OUT" ] || [ "$AGY_LAST" != "$AGY_MARKER" ]; then
echo "agy unavailable (empty output or missing completion marker) — Codex CLI only this round"
AGY_OUT=""
fi
fi
```
Parse `$AGY_OUT` for `[P*]` lines (ignore the marker line). agy may reply in a
non-English language — key off the `[P*]` tags and the marker, not the English
"No issues found." string.
If either CLI fails (rate limit, non-zero exit, "usage limit" in stderr, or —
for agy — empty/markerless output), proceed with whichever succeeded. If both
fail → stop, tell user, preserve commits.
3. Merge findings (`MERGED_FINDINGS`):
- For each Codex finding (file, line, topic), check if an agy finding overlaps:
same file, line within ±5, topic semantically similar → keep one (prefer the
more specific description).
- Result: deduped list of findings from both reviewers.
3b. VERIFICATION GATE (optional): at effective size L with the Workflow tool
available (S and M skip it), challenge MERGED_FINDINGS with the adversarial gate
before Step 4 (see the "Verification gate" section and
references/adversarial-verify.md). Pass MERGED_FINDINGS as
`findings` and this round's diff command (Range resolution table) as `diff_cmd`.
Replace MERGED_FINDINGS with the confirmed survivors; record rejected findings
as pushed back and carry their reasoning into prior-push-back context. If every
finding is rejected, MERGED_FINDINGS is empty and Step 4 treats it as a
push-back exit (findings existed but were all rejected), NOT a clean pass. Tool
unavailable → skip the gate; MERGED_FINDINGS unchanged.
4. Parse `MERGED_FINDINGS`:
- Empty because reviewers raised nothing this round → **clean pass, exit loop.**
- Empty because the verification gate (3b) rejected every finding this round →
**push-back exit, exit loop** (findings existed but were all refuted — not a
clean pass).
- All findings repeat prior rounds with the same reasoning already pushed back
→ **push-back exit, exit loop.**
- Otherwise → continue to Step 5.
5. Dispatch fix subagent with `MERGED_FINDINGS` and prior-round push-backs.
Hard constraints (same as Phase 2):
- Invoke `superpowers:receiving-code-review` first to evaluate findings.
- Edit source files directly.
- **Inner verify loop** (when `VERIFY_CMD` is set): after editing, run
`VERIFY_CMD` against the working tree **before the commit below**; commit
only on a green verify; on the 3rd failure return a structured halt (no
commit/push). Include the anti-gaming guard. See
[Inner verify loop](#inner-verify-loop-objective-verifier-gate).
- **After edits: `git add` + `git commit` + `git push`.** Commit message:
`fix: post-commit review fixes (round <N>) — <summary>`.
- **Do NOT amend. Do NOT create branch or PR.**
5b. Halt check: if the fix subagent returned a structured halt (no commit), stop
at the blocked exit and reference the `halts/` payload — do NOT run Step 6's
push gate (a halt leaves `HEAD == origin/main`, which would false-pass it) and
do NOT loop to the next round.
6. Hard gate: verify the fix subagent's push actually landed on `origin/main`.
If `HEAD != origin/main` (push rejected, skipped, or never happened), stop —
do NOT advance `TIP_SHA` and do NOT loop, otherwise the next round would
review unpushed local state and the final report would falsely claim the
commit was pushed:
```bash
git fetch origin main
LOCAL_HEAD=$(git rev-parse HEAD)
REMOTE_HEAD=$(git rev-parse origin/main)
if [ "$LOCAL_HEAD" != "$REMOTE_HEAD" ]; then
stop with: "Push verification failed — HEAD ($LOCAL_HEAD) does not match
origin/main ($REMOTE_HEAD). The fix subagent's push was rejected or skipped.
Investigate before continuing."
fi
```
Push confirmed. Update `TIP_SHA = HEAD`. If `RANGE_SPEC = single`, also set
`RANGE_SPEC = range` (keep `BASE_SHA` unchanged) so subsequent rounds review
the full cumulative range (`BASE_SHA..HEAD`) — not just the latest fix commit.
Loop back to Step 1.
End: max SIZE_MAX_ROUNDS rounds (S 3 / M 5 / L 10) → stop and report last round's findings; let user decide.
Exit Conditions
- Clean pass: Codex CLI reports no
[P*] findings, and agy either was
unavailable/failed this round or also reports none → done. (When agy is down
the round runs Codex CLI only, so Codex's clean result alone is the pass —
don't wait on a reviewer that didn't run.)
- Push-back exit: all findings repeat prior rounds with the same reasoning → done.
- Max
SIZE_MAX_ROUNDS rounds — S 3 / M 5 / L 10 by effective size (see
Sizing); the M default of 5 matches this mode's prior
fixed cap and stays lower than Uncommitted Mode's 10, since post-commit is a
follow-up review stage, not fresh implementation: stop and report last round; user decides.
- Aborted invariants: branch changed, BASE unreachable, both CLIs unavailable →
stop with specific reason.
Pre-exit push (clean pass / push-back / max rounds)
If the loop exits without ever entering a fix step (Phase 1 clean + Phase 3
round 1 clean), HEAD may still be ahead of origin/main with the reviewed
local-only commits unpushed — fix subagents handle their own push, but a
zero-finding fast path bypasses them entirely. Without this step, the final
report's Last commit pushed claim would be false:
git fetch origin main
if [ "$(git rev-parse HEAD)" != "$(git rev-parse origin/main)" ]; then
git push origin main
git fetch origin main
if [ "$(git rev-parse HEAD)" != "$(git rev-parse origin/main)" ]; then
stop with: "Pre-exit push failed — HEAD still does not match origin/main
after push. Investigate before reporting completion."
fi
fi
Skip for the Aborted invariants exit — that path indicates the loop is in
a bad state, don't publish anything.
Final report (on any exit)
Post-commit review loop complete.
- Range: <RANGE_SPEC>
- Exit reason: <clean pass / push-back / max rounds / aborted / halt>
- Rounds run: <N>
- Items fixed: <M> (across <K> new commits on top)
- Items pushed back: <P>
- Last commit pushed: <SHA>
Then append the Flags section (Inner verify loop → Flags) if anything flagged
this run — including "no objective verifier configured for this loop"; omit it
otherwise. On a halt, report blocked and reference the halts/ payload path.
Do not offer to amend or open a PR. Fixes live as new commits on main.
Phase 1: Internal Review
⏭️ Skip entirely if MODE=uncommitted.
⏭️ If external_only == true OR EFFECTIVE_SIZE == S, skip this phase — go to Phase 3. (Size S reviews externally only; see Sizing.)
Which reviewers run depends on EFFECTIVE_SIZE (see Sizing):
- M (default) → dispatch only rows 4 and 5 below (
/specialist-review + ponytail:ponytail-review).
- L → dispatch all 5 rows below.
- S → Phase 1 is skipped entirely (handled by the skip above).
Dispatch the selected subagents in parallel (run_in_background: true), each running a review skill. All report-only — no code changes.
| Subagent | Skill | Source | Focus |
|---|
| 1 | /simplify | Anthropic official | Check simplicity, reuse, quality, efficiency — report issues and specific fix suggestions only, do not modify files |
| 2 | superpowers:requesting-code-review | superpowers plugin | Self-check checklist — report only items that fail, with specific fix suggestions |
| 3 | /review | gstack | SQL safety, trust boundaries, conditional side effects, structural issues — report findings and specific fix suggestions only |
| 4 | /specialist-review | included | Tech-stack expert review — report findings and specific fix suggestions only |
| 5 | ponytail:ponytail-review | ponytail plugin | Over-engineering review: dead code, hand-rolled stdlib, unused abstractions, shrinkable logic — report only (tagged delete/stdlib/native/yagni/shrink) |
All skills are optional. If any subagent fails (skill not found, invocation error, or subagent error), log which skill was unavailable and why, skip that subagent, and continue waiting for others. For external plugins (e.g. ponytail), print a one-line install suggestion when unavailable.
- At least 1 subagent succeeds → proceed to Phase 2 (using completed reports)
- All fail → notify user "Phase 1: all internal reviewers unavailable", skip Phase 1 + 2, proceed to Phase 3
Each subagent prompt must include:
- PR diff (via
git diff main...HEAD)
- Explicit instruction: "report-only mode, do not modify any files"
- Required format: each suggestion includes file path, line number, issue description, specific fix suggestion (with proposed code)
Wait for all successful subagents to report, then proceed to Phase 2.
Phase 2: Consolidate + Fix
⏭️ Skip entirely if MODE=uncommitted.
⏭️ If external_only == true OR EFFECTIVE_SIZE == S, skip this phase — go to Phase 3.
2a. Consolidate reports
After receiving all successful reports:
- Merge and deduplicate: same suggestion for the same file and line → keep only one
- Group by file: list all suggestions organized by file
- Handle contradictions: when suggestions contradict each other, apply the
Findings-contradiction handling table.
Unattended runs follow the table (no prompt); attended runs surface it inline and
keep asking the user — the decision-point-flag
attended projection.
Verification gate (optional). At effective size L with the Workflow tool
available (S and M skip it), run the adversarial verification gate on the
consolidated suggestion list before dispatching 2b — see
Verification gate and
references/adversarial-verify.md. Pass the deduped suggestions as findings
and git diff main...HEAD as diff_cmd. Dispatch 2b with only the confirmed
(survivor) findings; record each rejected finding as pushed back (with the
skeptics' reasoning). If every finding is rejected, skip 2b and proceed to
Phase 3. Tool unavailable → skip the gate, pass the full list to 2b.
2b. Dispatch fix subagent
Hand the consolidated suggestion list to a subagent. The prompt must include:
- Full content of all suggestions (file, line, issue description, proposed fix)
- Instruction: "Use the
superpowers:receiving-code-review skill framework to evaluate each suggestion"
- Instruction: "False positives require solid technical reasoning to push back"
- Instruction: "After fixes, commit + push"
- Inner verify loop (when
VERIFY_CMD is set): run VERIFY_CMD against the
working tree before committing; commit only on a green verify; on the 3rd
failure return a structured halt (no commit). Include the anti-gaming guard.
See Inner verify loop.
- Commit message format:
fix: internal review fixes — <summary>
Agent(
description: "Process internal review feedback",
prompt: "Here are the consolidated suggestions from internal reviewers:\n\n<SUGGESTIONS>\n\nInvoke the superpowers:receiving-code-review skill first, use its framework to evaluate each one, fix items worth fixing. If a VERIFY_CMD was provided, follow the Inner verify loop: run it against the working tree before committing and commit only when it passes (3rd failure → structured halt, no commit). Then commit + push."
)
Halt check. If the subagent returned a structured halt (no commit), stop at the
blocked exit and reference the halts/ payload — do NOT treat the absent commit as
a clean push in 2c, and do NOT advance to Phase 3.
2c. Confirm push succeeded, then proceed to Phase 3.
Phase 3: External Review Loop
⏭️ Skip entirely if MODE=uncommitted.
Step 0: Read existing PR feedback
