| description | Dispatch-shaped code review: fan the diff out to fresh-context reviewers
across diverse providers and model families, synthesize, fix blockers,
re-review until clean. Use when: "review this", "code review", "is this
ready to ship", "second-model review". Trigger: /code-review, /review.

You are the marshal. Read the diff, dispatch diverse fresh-context
reviewers, synthesize, fix blockers, loop until clean. The authoring agent
never ships on its own review — that is the one hard rule.
Dispatch
- Scope = the diff.
git diff <base>...HEAD (default base: the repo's
default branch). Classify what changed: API, UI, security surface, data
model, infra, docs.
- Learnings audit. Grep matched learnings before dispatch:
rg -n --glob '*.md' '^(title|tags|applies_when):|<module>|<failure-mode>' docs/solutions.
For each applicable match, the synthesis includes
followed|violated <learning title> <file:line> <why>; no file:line means
the verdict is not anchored.
- Choose the risk tier. Use
harnesses/shared/references/quality-system.md to decide whether the diff
needs a tiny, substantive, high-stakes, or Mode B review topology. Scale to
the failure cost, not to habit.
- Fan out in parallel, decorrelated. Native subagents for focused
lenses (pick 2–4 that fit the diff: correctness, security, simplicity,
tests); peer harness CLIs (
/roster) for cross-model judgment — a
different model family has decorrelated failure modes. If the harness can run a
large-scale background orchestration where reviewers adversarially
cross-check each other's findings before reporting, a substantive diff
is a natural fit — that scale costs tokens, so routine diffs don't get
it. Reviewers get the diff, the acceptance oracle, and a risk lens —
never the author's reasoning trail. When the delivery logged
deviations, hand reviewers the deviation sites — where the plan bent is
where plausible-but-wrong concentrates — but never the author's
justifications for them.
Add harnesses/shared/references/works-critique.md when the diff touches
public API, CLI, UI, performance, compatibility, migration, or operator
workflow. Add harnesses/shared/references/delete-first.md when the diff
adds abstraction, automation, dependencies, modes, or optimization; pair it
with the synced Ponytail skill
(skills/.external/dietrich-ponytail/SKILL.md) when the main risk is bloat,
boilerplate, or speculative engineering.
Add the synced Thermo-Nuclear skill
(skills/.external/cursor-thermo-nuclear-code-quality-review/SKILL.md)
whenever the diff changes meaningful implementation structure, grows large
files, adds wrappers, or risks spaghetti branching; this is the default
harsh maintainability lens, not a last resort.
Add harnesses/shared/references/verification-system-first.md when the
diff's proof story is missing, weak, eval/benchmark-shaped, or depends on
QA/manual judgment.
- Aim reviewers at production embarrassment, not nitpicks. Tell each
one what to ignore (style, naming, speculative "consider…") as
explicitly as what to find.
What reviewers hunt
Plausible-but-wrong is the failure mode of model-written code:
- Stub or specification-shaped implementations that pass tests but don't work
- Wrong complexity (O(n²) hiding behind a clean interface)
- Tests that never invoke the changed entrypoint (adjacent green lanes)
- Missing verification system: no claim, falsifier, driver, grader, evidence
packet, or cadence for a substantive change
- Missing invariant checks that only matter at scale or under concurrency
- Unnecessary abstraction — wrappers, modes, layers that don't earn their keep
- Swallowed errors, magic fallbacks, internal mocks
If the diff adds or changes an executable path (CLI, script, migration, job),
someone must run it once or cite the gate that does — otherwise it's an
unverified runtime path and blocks Ship. If the diff touches a visual or
user-facing surface, at least one reviewer exercises it live.
If the diff claims eval, benchmark, QA, or agent-behavior improvement, reviewers
must inspect the driver and grader, not just the report prose.
Synthesize and verdict
Dedupe across reviewers; rank blocking (correctness, security, unverified
runtime path) > important (architecture, test strength) > advisory
(everything else). Blocking findings get fixed and the fix re-reviewed —
full pass, not a spot-check. Max 3 fix-review iterations, then escalate to
the operator with the open findings. Ship / Don't-ship is the lead's call on
the reviewers' evidence; advisory findings never block.
When the receipt pile is large, use julius-caveman compression for the
synthesis only. Findings must stay precise; PR comments and code suggestions
stay normal English unless the operator explicitly asks otherwise.
Gotchas
- Monoculture. Same-model subagents alone are groupthink with extra
steps. Substantive diffs get at least one other model family.
- Reviewing the repo instead of the diff. Scope discipline keeps
findings actionable.
- Treating all findings equally. Severity ranking is the marshal's job;
a wall of undifferentiated comments is review theater.
- Skipping re-review after fixes. A fix can introduce the next bug;
blockers get a fresh pass.
