name	pr-deslop
description	Use when the user wants to clean AI slop, verbosity, fragile hard-coded references (line numbers, test counts, file counts), or low-value contributions out of a branch's commits before review. Triggers on phrases like "deslop", "remove AI slop", "clean up commits", "tighten the commits", "fix verbose commit messages", "drop the fluff", "remove brittle counts", "kill the line-number references", "audit the branch for slop", "scrub Claude signatures", or "fixup the slop on this branch". Operates per-commit since trunk: detects issues, proposes targeted patches and fixup commits (and `--fixup=reword:` for commit-message slop), then optionally runs `git rebase -i --autosquash`, running the project's formatter, linter, and type-checker on every conflict pause.

this skill

Audit-first, autosquash-on-explicit-opt-in slop cleaner. Reviews every commit on the current branch since trunk for AI slop, verbose code/comments, fragile hard-coded references, and low-value contributions. Produces a numbered patch series under .git/deslop/<ts>-<pid>/ plus a checkpointed apply.sh. With --apply-rebase, applies aggregated fixups (one per target SHA) and runs git rebase -i --autosquash, delegating conflict resolution to the project's discovered quality gates.

The skill refuses to operate on already-pushed branches unless --force-rewrite-pushed is passed, and refuses --apply-rebase entirely if the branch contains merge commits since trunk (git rebase -i --autosquash without --rebase-merges silently flattens topology).

Subjective findings are calibrated against the project's accepted voice on origin/<trunk> (not HEAD) before being flagged. The skill auto-applies only Tier A signals; Tier B is user-confirmed per finding; Tier C is advisory only.

This is a slash command, not a model-invocable skill — history rewrites must be user-explicit, not router-inferred.

Core thesis

Slop is a workflow label, not proof the text is wrong. The skill's job is to reduce review-hostile noise, not to scrub the user's voice. Three disciplines:

1. Audit-first, autosquash-on-explicit-opt-in. Default produces a patch series plus a checkpointed apply.sh. --apply-rebase is the explicit opt-in.
2. Three severity tiers govern auto-apply. Tier A (deterministic, near-zero FP) is auto-applied. Tier B (high-confidence regex with edge cases) is user-confirmed per finding. Tier C (subjective tone) is advisory only and calibrated against the project's accepted voice on origin/<trunk>.
3. Refuse, don't warn, on dangerous topologies. Pushed branches require --force-rewrite-pushed. Branches with merge commits refuse --apply-rebase entirely.

Slop includes branch-internal narrative bleed — within-branch tactical decisions (renames of unshipped symbols, intermediate states, phantom ### Fixes) that leak from commits into the artifacts being committed. Reviewing the diff and the commit message for those phrasings is part of the audit; the rule and the Published-Release Test are in AGENTS.md § AI Slop Prevention.

$ARGUMENTS contract

If $ARGUMENTS is empty, default to <trunk>..HEAD (trunk auto-detected; see Step 1) and confirm before scanning.

Flag	Default	Effect	Interaction
--apply-patches	off	Materialize patches under .git/deslop/<ts>-<pid>/; stop after generating apply.sh.	Redundant when paired with --apply-rebase (no error).
--apply-rebase	off	Run apply.sh then git rebase -i --autosquash. Destructive.	Strict superset of --apply-patches. Requires --force-rewrite-pushed on pushed branches. Refused entirely if branch has merge commits. Requires --since to be an ancestor of HEAD when set.
--budget=<level>	default	Tier ceiling (see Step 7).	Independent of --targets.
--targets=<list>	both	One of diff, messages, both.	--message-only and --diff-only are shorthands; cannot combine with --targets.
--message-only	off	Shorthand for --targets=messages.	Mutually exclusive with --diff-only and --targets.
--diff-only	off	Shorthand for --targets=diff.	Mutually exclusive with --message-only and --targets.
--since=<ref>	auto	Override trunk detection.	Skips Step 1's auto-detection. With --apply-rebase, must be an ancestor of HEAD (verified at Step 1).
--force-rewrite-pushed	off	Required when branch was pushed. Mirrors git push --force ergonomics.	No effect on local-only branches.
--run-tests	off	Include the discovered test command in conflict-loop gates and final verification.	Independent.
--no-semantic	off	Skip per-commit semantic verifier; regex-only.	Independent.
--taxonomy=<path>	built-in + .claude/deslop.local.yml overlay	Replace registry entirely.	When set, both built-in and user overlay are ignored.

Any non-flag tokens are treated as a commit range (<sha>..<sha> or single SHA) and override <trunk>..HEAD.

Boundary with the pr-review-pr skill

Skill	Surface	Posture
the pr-review-pr skill	The PR description on GitHub	Read-only — only reports findings, per its Rules section in the pr-review-pr skill.
this skill	The branch's commits (diffs + messages)	Patch series → optional aggregated fixups → optional autosquash. Never edits the PR description.

Bidirectional: neither skill modifies the other's surface. deslop may suggest running the pr-review-pr skill afterward when it spots PR-description problems; it never invokes it.

the pr-review-pr skill already includes a "No brittle details" rubric in its quality-patterns table (the pr-review-pr skill). this skill reuses that rubric as Tier A/B core and extends it with the broader signature registry.

Orchestration Plan

Per the Orchestration Plan Convention defined in this repo's top-level conventions file, this skill must enter plan mode before any analysis runs.

1. Enter plan mode. Activation hints by host:

• Claude Code: EnterPlanMode
• Cursor / Codex / Gemini: /plan or Shift+Tab

2. Build the orchestration plan containing:

1. The detected trunk ref and commit count to scan.
2. The active --budget and --targets settings.
3. Discovered quality-gate commands per bucket (set / unset / prompt-user for format, lint, typecheck, test).
4. Active mode (audit / --apply-patches / --apply-rebase).
5. Branch topology (local-only / pushed / contains-merge-commits).
6. Findings summary as ranges (pre-execution estimate). Step 12's final report uses post-hoc exact counts.

3. Present the plan and wait for explicit user approval.

4. Exit plan mode before executing Step 1 onward.

If plan mode is unavailable in the host, the Steps 1–12 phase structure still guides analysis-before-execution.

Step 1: Detect trunk, lock baseline, snapshot branch state

Detect trunk using the same pattern as the sibling /rebase command (the rebase skill):

git remote show origin 2>/dev/null | grep 'HEAD branch' | awk '{print $NF}'

Fall back to main, then master, if detection fails.

Pointer-drift lock. Resolve trunk to an absolute SHA at this step and reuse that SHA throughout the run — protects against background git fetch shifting the baseline mid-run:

git rev-parse "origin/${TRUNK}"

Store as BASELINE_SHA. Subsequent steps reference ${BASELINE_SHA}, not origin/${TRUNK}.

git rev-parse --abbrev-ref HEAD

git status --porcelain

git log --oneline "${BASELINE_SHA}..HEAD"

git log --merges --oneline "${BASELINE_SHA}..HEAD"

If --since=<ref> was passed AND --apply-rebase is set, verify it is an ancestor of HEAD — autosquash on a sibling branch will destroy topology:

git merge-base --is-ancestor "<ref>" HEAD

Halt with a clear message if any of these is true:

• Working tree is dirty (git status --porcelain non-empty; includes dirty submodules — single check covers both).
• git log --oneline "${BASELINE_SHA}..HEAD" emits no lines.
• Current branch is the trunk itself.
• A rebase is already in progress (.git/rebase-merge/ or .git/rebase-apply/ exists).
• HEAD is detached.
• Branch contains merge commits AND --apply-rebase was requested (refuse --apply-rebase; --apply-patches is permitted).
• --since=<ref> was passed AND --apply-rebase is set AND the ref is not an ancestor of HEAD.

Step 2: Pushed-branch gate

git rev-parse --abbrev-ref --symbolic-full-name '@{u}' 2>/dev/null

If no upstream, the branch is local-only; continue.

If an upstream exists:

git rev-parse --verify '@{u}'

git merge-base --is-ancestor "$(git rev-parse '@{u}')" HEAD

If merge-base --is-ancestor returns 0, the upstream is reachable from HEAD — the branch was pushed. Without --force-rewrite-pushed, refuse:

This branch was already pushed to <upstream>. Rewriting its history will require force-push and may break any reviewer's local checkout. Re-run with --force-rewrite-pushed to override, or use --apply-patches only (no rebase) to produce a patch series the user can review.

If --force-rewrite-pushed was passed, record the upstream name in the final report and continue.

Step 3: Discover quality gates (language-agnostic, merge across files)

Read references/quality-gates.md for the full procedure. Summary:

1. Read all of these files that exist (do not stop at the first):

   • ./AGENTS.md
   • ./CLAUDE.md
   • ./.github/CONTRIBUTING.md

2. Parse each into sections by heading. For each section whose heading matches format, fmt, style, lint, typecheck, tsc, mypy, pyright, test, spec, quality, or checks (case-insensitive substring match), extract the first fenced code block and capture its first command line.

3. Bucket commands as format, lint, typecheck, test. Merge across files in priority order: AGENTS.md first, then CLAUDE.md, then .github/CONTRIBUTING.md. A bucket unset after the first file is filled by the next.

4. Manifest sniffing is never a default. If a manifest exists and a bucket is still unset, present example commands via ask-user-choice and require explicit selection before storing. Never auto-inject pytest, npm test, cargo test, etc.

5. If no conventions file and no manifest, ask via ask-user-choice:

   I could not find AGENTS.md / CLAUDE.md describing your project's quality gates. What command should I run after each conflict resolution? You can answer 'skip' to disable quality gates.

This is the language-agnostic discipline mandated by the repo's Language-Agnostic Design rule.

Cache the resolved commands as FORMAT_CMD, LINT_CMD, TYPECHECK_CMD, TEST_CMD. Empty buckets are skipped in Steps 11 and 12.

Step 4: Read project tone (calibrate Tier C against trunk)

Calibrate against trunk's accepted voice — not HEAD, where unreviewed slop on the branch could whitelist itself.

1. Search the conventions files from Step 3 for headings like tone, style, prose, writing, voice. Capture any directives.

2. Read the last 50 commit messages on the locked baseline:

   git log -n 50 --format='%B%n--END--' "${BASELINE_SHA}"
   

3. Build a frequency map of Tier C signal phrases. Default demotion threshold: ≥ 3 occurrences in the last 50 trunk commits. Phrases meeting the threshold are demoted from Tier C-active to advisory-only-in-summary for this run.

A flat regex list applied to every project will generate false positives the user cannot disable, and they will stop trusting the tool.

Step 5: Load the signatures registry

Built-in registry path: references/signatures.yml. Read via the Read tool.

Project override: .claude/deslop.local.yml if present in the repo root.

The override file declares three explicit operations (replacing the ambiguous single extends: key):

• replace: — list of signature ids; each id replaces the built-in entry of the same id with the user's definition.
• append: — list of new signatures (must use ids not present in built-in).
• delete: — list of built-in signature ids to remove from this run.

The three keys are mutually disjoint per id. If the override declares the same id under more than one key, refuse with a parser error.

If --taxonomy=<path> is passed, that path replaces both built-in and user overlay. If the override is malformed, refuse with a parser error pointing to the offending line; do not silently fall back to built-in only.

If .claude/deslop.local.yml is tracked by git AND currently dirty, warn that --apply-rebase may pause if a fixup touches it, and advise committing or stashing before applying.

Print: "Loaded N signatures (B builtin, R replaced, A appended, D deleted; tone calibration demoted X)."

Step 6: Detect (two-pass hybrid)

Cost-saving framing: regex first (cheap, deterministic), semantic only on flagged hunks (expensive, precise).

Pass A — Regex (always runs)

For each enabled signature, run its pattern against:

• target: diff — git diff "${BASELINE_SHA}..HEAD" (per-hunk).
• target: message-subject — each commit's subject line.
• target: message-body — each commit's body.
• target: file — staged file content per commit.

Each match produces a candidate finding: {commit_sha, signature_id, location, tier, confidence: regex, action}.

Pass B — Semantic verifier (skip with --no-semantic)

Dispatch a Task sub-agent — one per commit, capped at 8 concurrent. Sub-agent contract (enforced via the prompt, not via separate agent file):

• Allowed tools: Read, Grep, Glob.
• Disallowed: Bash, Write, Edit, Task.

Each invocation receives:

• The commit's full diff (git show <sha> content embedded in the prompt).
• The commit's full message.
• The registry filtered to kind: semantic.
• The Step-4 tone calibration result.

Anti-slop-on-slop constraint. The sub-agent's prompt must include:

Do not introduce slop in your suggested replacements. Do not use phrases listed in the registry. Do not narrate your changes ("I tightened…"). Replacement text should be concrete and shorter than the original where possible.

The sub-agent returns a JSON list of findings. Parse resiliently:

1. Strip markdown fences (```json … ``` or plain ``` … ```).
2. Extract the first balanced [ … ] from the response.
3. Parse. On failure, mark verifier=skipped-for-<sha> for that commit and fall back to that commit's Pass A findings only. Do not crash the run.

Findings are joined to Pass A by (commit_sha, location):

• semantic confirms — confidence upgraded.
• semantic denies — finding dropped.
• semantic-only — added fresh.

If Task is unavailable, mark verifier=skipped globally and continue with Pass A only.

Step 7: Apply tiers, budget, and grouping

Budget	Tier A	Tier B	Tier C
strict	auto-apply all	none in proposal (advisory)	none (silently skipped)
default	auto-apply all	up to 5 in proposal, rest advisory	up to 10 advisory
lax	auto-apply all	up to 10 in proposal	unlimited advisory

Within each tier, rank findings by (commits_affected DESC, confidence DESC, signature_id ASC) and take the top N per the budget. Remaining findings become advisories in the report.

Group findings by target commit:

Finding scope	Patch shape	Tool (git ≥ 2.32)	git < 2.32 fallback
Diff slop in commit X	One fixup commit per X (aggregated from N patches)	git commit --fixup=<X>	Same.
Subject-only or body slop in commit X	One reword fixup per X	git commit --fixup=reword:<X>	Empty fixup + manual reword note in apply.sh
Diff AND message slop in commit X	One amend fixup carrying tree + message	git commit --fixup=amend:<X>	Two fixups: --fixup=<X> for diff + manual reword note for message
Whole-commit low-value	drop line in git-rebase-todo	sequence-editor honors it	Same.

--fixup=amend: and --fixup=reword: are documented in git commit --help, available since git 2.32. The pre-2.32 fallback preserves diff fixups rather than refusing across the board — only message rewrites become manual notes.

git interpret-trailers is not a general message-rewrite tool — only narrow trailer cleanup. --fixup=reword: is the canonical mechanism for message rewrites.

Step 8: Materialize the patch series

Always materialize first — this is the user's review surface.

The directory uses <ts>-<pid> to prevent collisions on fast double-invocation (second-precision timestamps race):

mkdir -p ".git/deslop/$(date -u +%Y%m%d-%H%M%SZ)-$$"

Layout:

.git/deslop/<ts>-<pid>/
├── 0000-PLAN.md                 (plan + registry source path + SHA-256)
├── 0001-fixup-<sha>-<id>.patch  (per-finding diff patches)
├── 0002-reword-<sha>.txt
├── 0003-amend-<sha>.patch
├── 0004-drop-<sha>.note
├── 0005-advisory.md
├── reword/
│   └── <sha>.txt                (one file per target SHA needing reword)
├── reword-map.tsv               (autosquash-subject → target-sha → reword-file)
├── .checkpoint/                 (per-step durable markers for apply.sh idempotency)
└── apply.sh                     (rendered from references/apply-template.sh)

0000-PLAN.md records: registry version, registry source path (built-in or --taxonomy=<path>), registry SHA-256, resolved FORMAT_CMD / LINT_CMD / TYPECHECK_CMD / TEST_CMD, BASELINE_SHA, commit range, budget, tone-calibration result.

Patch aggregation per target SHA: one fixup commit per target, not one fixup per finding. Multiple .patch files for the same target are visible artifacts (one per finding for reviewability), but apply.sh applies them all to the working tree before creating the single fixup. See references/apply-template.sh for the patch driver template.

apply.sh is the single artifact the user runs. Idempotent via durable per-step checkpoints; re-running skips completed steps. Re-reads the registry source path recorded in 0000-PLAN.md, recomputes its SHA-256, and aborts if changed since materialization.

If --apply-patches was passed without --apply-rebase, stop here. The user runs bash .git/deslop/<ts>-<pid>/apply.sh themselves.

.git/deslop/ is run-scoped, not a permanent record. Git ignores subdirectories of .git/ that aren't its known data directories; the patch files are POSIX files, not git objects.

Step 9: Confirmation gate

Use ask-user-choice:

Choice	Effect
Patches only (default)	Files written; nothing applied.
Apply patches now	Run apply.sh; create fixup commits on HEAD; do not rebase.
Apply and autosquash	Full rewrite. Only offered if --apply-rebase was passed AND no merge commits were detected in Step 1.
Cancel	Delete .git/deslop/<ts>-<pid>/ and exit.

For "Apply patches now" the skill must show this warning before proceeding:

Fixup commits will be on HEAD. Run git rebase -i --autosquash <trunk> yourself before pushing, or reviewers will see the raw fixup! / amend! commits. The Step-10 backup branch is created for this option too.

If the skill was invoked without --apply-rebase, the third option is hidden.

Step 10: Backup and apply

Before any history-affecting action — including the middle option — create the backup branch:

git branch "$(git branch --show-current)-pre-deslop-$(date -u +%Y%m%d-%H%M%S)"

Record the backup branch name in the final report. Tell the user: the original branch state is preserved at this branch; if anything goes wrong they can git reset --hard <backup>.

Apply patches:

bash ".git/deslop/${TS_PID}/apply.sh"

apply.sh aggregates per target. For each target SHA, it applies all relevant .patch files to the working tree, stages explicit paths, and creates one fixup commit per target. See references/apply-template.sh for the full contract.

Never git add -A or git add . — explicit paths only, per the commit skill (rule line 187). This rule applies to the patch driver too.

If the user chose "Apply patches now" (middle option), stop here. Steps 11–12 only run for "Apply and autosquash".

For autosquash, run with rerere enabled. The reword fixup commits already carry their replacement messages in their bodies (Step 8's apply-template.sh pre-stages the message with an amend! <subject> prefix line), so autosquash uses the body verbatim — no editor needs to be invoked, and no shim is required:

GIT_SEQUENCE_EDITOR=: git -c rerere.enabled=true -c rerere.autoupdate=true rebase -i --autosquash "${BASELINE_SHA}"

GIT_SEQUENCE_EDITOR=: accepts the auto-generated todo list non-interactively; autosquash strips the amend! <subject> prefix from each fixup body and uses the remainder as the target's new commit message.

If autosquash exits 0, jump to Step 12.

Step 11: Conflict loop (rerere-safe, gates touched-first)

This loop is borrowed from the rebase skill (Phase 4 of /rebase) with three tightenings. See references/conflict-loop.md for the full discussion.

Tightening 1 — gates touched-first then full set. After resolving each pause, re-run only the gates relevant to touched files. The full discovered gate set runs once at Step 12.

Tightening 2 — tests are opt-in. Default off (TEST_CMD skipped). Pass --run-tests to include per-pick.

Tightening 3 — track git diff --cached alongside unmerged files. rerere.autoupdate=true auto-resolves and stages previously-seen conflicts, removing the conflict markers. Validate both unmerged and staged paths to ensure the formatter and linter see rerere's output.

The loop:

1. Inspect both unmerged and staged files:

   git diff --name-only --diff-filter=U
   

   git diff --name-only --cached
   

2. For each file with conflict markers (<<<<<<<), read it and resolve. Prefer the incoming (fixup) side for targeted lines; preserve other structural changes from trunk-side context. When uncertain, surface the conflict via ask-user-choice rather than guessing.

3. Stage explicit paths only:

   git add -- <file>
   

4. Run touched-file gates (skip empty buckets):

   ${FORMAT_CMD}
   

   ${LINT_CMD}
   

   ${TYPECHECK_CMD}
   

   • Formatter auto-applies. Re-stage modified files explicitly.
   • Linter with --fix auto-fixes; re-stage. Hard errors surface via ask-user-choice with three options: Edit and continue, Skip this fixup (git rebase --skip), Abort (git rebase --abort).
   • Type checker never auto-modifies. Errors surface as linter-hard.
   • Tests only if --run-tests was passed; same triage as type-check.

5. Continue:

   git rebase --continue
   

6. If the next pick conflicts, loop from step 1. rerere replays prior resolutions automatically; the touched-file gates in step 4 validate rerere's output before the rebase advances.

7. Unrecoverable:

   git rebase --abort
   

   Report what failed. Remind the user the backup branch from Step 10 exists.

Step 12: Final verification and report

git log --oneline "${BASELINE_SHA}..HEAD"

git status --porcelain

Run the full discovered gate set on the tip (skip empty buckets):

${FORMAT_CMD}

${LINT_CMD}

${TYPECHECK_CMD}

If --run-tests was passed:

${TEST_CMD}

The final report uses post-execution counts — these are post-hoc fact, distinct from the Orchestration Plan's pre-execution range estimates.

Edge cases

Case	Behavior
Merge commits in range + --apply-rebase	Refused at Step 1 (autosquash without --rebase-merges flattens topology). --apply-patches is permitted.
Merge commits in range + --apply-patches only	Permitted; patches written for review. User can rebase manually with --rebase-merges.
--since=<ref> not an ancestor of HEAD with --apply-rebase	Refused at Step 1.
Root commit	Warn and require git rebase --root.
Empty diff after edit	Skip the fixup; record as "no-op".
Already-pushed branch	See Step 2.
Branch is the trunk	See Step 1 halt list.
Detached HEAD	See Step 1 halt list.
Concurrent rebase in progress	See Step 1 halt list.
Single-commit branch + no body	Reword fixup is right; autosquash collapses cleanly.
--message-only on diff slop	Run, report skipped diff findings, only build reword fixups.
No conventions file and no manifest	Step 3.5 prompts user; empty buckets are skipped in Steps 11/12.
Worktrees	Permitted — <trunk>..HEAD model unaffected.
.git/deslop/ collision (race or restart)	<ts>-<pid> directory naming guarantees uniqueness.
Pre-existing --fixup! / --amend! commits on branch	Detect via git log -E --grep='^(fixup|amend)!'; offer to autosquash them as a precondition.
Non-UTF-8 commit message	Skip slop checks on the message; report warning.
Pre-commit hook modifies staged content during fixup	apply.sh aborts the affected step with the hook's stderr; user resolves and re-runs. The skill never uses --no-verify.
.gitignore intersection (patch ignores file the patch modifies)	git add errors out; apply.sh aborts that step with an actionable error pointing to both files.
Sub-agent fails / times out / parses non-JSON	Mark verifier=skipped-for-<sha>; fall back to Pass A. Do not crash.
User override .claude/deslop.local.yml malformed	Refuse with parser error. Do not silently fall back.
User override is git-tracked AND dirty	Warn at Step 5.
--taxonomy=<path> points at missing file	Refuse with path-resolution error.
User-overridden registry disables every signature	"No active signatures — nothing to detect." Exit 0.
Git < 2.32 (no --fixup=reword: / --fixup=amend:)	Detect via git --version. Diff fixups still work. Message rewrites become per-fixup notes requiring manual git rebase -i. Warn the user.
Live registry diverged between materialize and apply	0000-PLAN.md records source path + SHA-256. apply.sh recomputes, aborts on divergence.
Terminal codepage prevents emoji unicode read	Read signatures.yml as UTF-8 bytes; never rely on locale-default decoding.

What this skill does NOT cover

• The PR description on GitHub — the pr-review-pr skill's job. Never edit it from this skill.
• Full rebase onto trunk — /rebase's job.
• New commit creation — /commit's job.
• Pushing the rewritten branch — explicit user action, never automatic.
• Auto-splitting multi-topic commits — flagged advisory; manual via git rebase -i.
• Auto-applying Tier C suggestions — never. Prose voice belongs to the author.
• Pre-commit prevention — that's a future PostToolUse hook (see below).

Future: PostToolUse preventative hook (not shipped here)

The right preventative layer is a PostToolUse hook on Bash matching ^\s*git\s+commit\b, in the commit plugin — which ships no hooks today. It would inspect the just-created commit message and warn (not block) on Tier A signals. The user can then run this skill --message-only.

PostToolUse is correct over PreToolUse: blocking the agent's tool call mid-flight is invasive UX, while warning on an already-created commit (recoverable via git commit --amend or git reset --soft HEAD~1) is a softer touch.

The hook is not shipped in this skill — it is reserved as a follow-up. No plugin in this repo currently has a hooks/ directory; introducing the first one warrants its own change.

• Bundled files — every relative path in this skill points at a file shipped inside this skill directory. Read them from here, not from the host's plugin tree.
