name: lint-cleanup-loop description: Autonomous doc-rot reduction loop modeled on karpathy/autoresearch's program.md pattern. Picks one stale-version ref / dead link / orphan / missing-doc at a time, fixes it, re-lints, commits if the metric improved, advances or resets. Runs until 0 findings or N stuck iterations. argument-hint: [--category stale_versions|dead_links|orphan_features|missing_features|all] [--max-iters N]

Lint Cleanup Loop

This skill is autonomous. Once kicked off, it runs the experiment loop indefinitely. Do not pause to ask the user "should I keep going?". The user may be asleep or away. Stop only when the metric hits 0, when N consecutive iterations make no progress, or when the user manually interrupts.

Modeled on Karpathy's autoresearch program.md pattern. The full mapping:

autoresearch	this skill
train.py (agent edits)	DOTS docs touched per iteration
prepare.py (read-only)	tools/lint_docs.py — the ground-truth metric
program.md (human edits)	This file
val_bpb (metric, lower is better)	total_findings from lint_docs.py --summary
results.tsv (untracked)	.claude/state/lint-cleanup-loop/results.tsv (gitignored)
autoresearch/<tag> branch	dots-lint/<tag> branch
5-min time budget	per-iteration soft cap: 10 min wall clock
"keep" / "discard" / "crash"	same
"NEVER STOP"	same

Setup

1. Agree on a run tag: propose one based on today's date (e.g. may27a). The branch dots-lint/<tag> must not already exist.
2. Create the branch: git checkout -b dots-lint/<tag> from current HEAD.
3. Pick the category from $ARGUMENTS (default all). One of:
   • stale_versions — the largest category (184 today), mostly 1.3.15-era references that should be 1.4.5
   • dead_links — markdown link targets that don't resolve
   • orphan_features — feature docs that no other doc references
   • missing_features — Main/Features/<X>/ without docs/features/<x>.md
   • all — run the linter on the full set; pick whichever has the highest count
4. Capture baseline: run python tools/lint_docs.py --summary and record the metric. Karpathy's "first run = baseline" rule (autoresearch program.md "The first run").
5. Initialize results.tsv: at .claude/state/lint-cleanup-loop/results.tsv with header commit\tcategory\tcount_before\tcount_after\tstatus\tdescription. Untracked by git — same convention as autoresearch/results.tsv (in .claude/state/ which is gitignored).
6. Confirm with user (one time only): "Baseline is N findings in category X. Starting the loop. I will NOT stop to ask for permission once running."

Once confirmed, kick off the loop. Do not seek further confirmation until the metric reaches 0 or N consecutive iterations make no progress.

The experiment loop

LOOP FOREVER (until stop condition):

1. Look at git state — current branch + most recent commit.
2. Run lint + pick one finding to fix:
   • python tools/lint_docs.py > .claude/state/lint-cleanup-loop/last-lint.md 2>&1
   • Read the report; pick a finding in the chosen category. Prefer findings clustered in one file (one Edit fixes many).
3. Fix the finding — Edit the doc(s). Examples:
   • Stale 1.3.15 ref: if the context describes current v1.4.5 behavior, update. If it describes historical v1.3.15 research, leave it (and re-evaluate whether the file's name should match rca- or codex-adversarial- prefix to get auto-exempted).
   • Dead link: find the renamed/moved target, or convert to inline-code prose if the target lives outside the repo (e.g., memory files).
   • Orphan feature doc: add a link from docs/INDEX.md to that doc, or delete the doc if it's vestigial.
   • Missing feature doc: scaffold from docs/features/TEMPLATE.md. Read the corresponding Main/Features/<X>/ source first.
4. git commit the fix with a 50-char-or-fewer title:

   docs(lint): fix <N> <category> in <file-or-area>
   

5. Re-run lint to measure delta:

   python tools/lint_docs.py --summary > .claude/state/lint-cleanup-loop/post.txt 2>&1
   

6. Extract the metric: grep "^total_findings:" .claude/state/lint-cleanup-loop/post.txt (or the category-specific line).
7. Record in results.tsv (tab-separated): commit\tcategory\tbefore\tafter\tstatus\tdescription.
8. Advance or reset:
   • improved (count decreased) → keep the commit. Loop continues.
   • equal or worse → git reset --hard HEAD~1. Status = discard. Loop continues.
   • lint crashed (no output) → git reset --hard HEAD~1. Status = crash. Loop continues.

Stop conditions

Stop ONLY when one of:

• Metric hits 0 in the chosen category. Print: "Done. reduced to 0."
• 5 consecutive iterations with no improvement (5 discards in a row). Print: "Stuck — 5 consecutive non-improvements. Stopping."
• User manually interrupts (Ctrl-C, etc.).
• Iteration budget exceeded (--max-iters N, default unlimited).

Do NOT stop to ask permission. Do NOT stop because the changes feel "too repetitive". Do NOT stop because you want a code review — the commits ARE the review surface.

Crash judgment (per autoresearch program.md)

• Trivial bug (typo in Edit, file not found because user moved it mid-loop) → fix and retry the same finding once. If retry fails, treat as discard and move on.
• Fundamentally broken approach (the fix you tried makes the metric worse OR introduces other errors) → discard, log crash, move on to a different finding.
• 3 consecutive crashes on different findings → stop and report. Something is wrong with the linter or the docs format.

Output capture discipline (per autoresearch program.md)

• > file 2>&1 — never tee, never let lint output flood the conversation context.
• After each lint run, only grep the specific lines you need from the captured file.
• tail -n 50 if you need to debug a crash.

Simplicity criterion (per autoresearch program.md)

When choosing what to fix:

• Deleting a stale doc that's not referenced anywhere AND no longer accurate → always keep.
• Adding a TEMPLATE-scaffolded feature doc with minimal content just to satisfy the linter → reject; the doc must be genuinely useful or the gap stays.
• A 1-line fix that resolves 30 stale-version refs (e.g., updating a single migration table header) → big win.
• A 50-line refactor that resolves 2 dead links → bad ratio; skip and find a different finding.

Branch + merge discipline

The loop runs on dots-lint/<tag> — isolated branch, no risk to bannerlord-1.4.5. When the loop stops (metric=0 or stuck):

1. Print a final summary block:

   ---
   tag:           <tag>
   category:      <category>
   start_count:   <baseline>
   end_count:     <final>
   iterations:    <N>
   commits:       <kept>
   discards:      <reset>
   crashes:       <crash>
   ---
   

2. Tell the user the branch is ready for review. Do not auto-merge to bannerlord-1.4.5. The user decides.

What NOT to do

• Don't run /lint-docs and stop — that's diagnostic, not action. This skill DOES the fixes.
• Don't fix C# build errors, test failures, or feature bugs — this is a docs-only loop. If a fix would require touching Main/, skip the finding.
• Don't update CHANGELOG mid-loop — wait until the branch is ready and let the user write one batch entry.
• Don't pause to ask "is this fix correct?" — the metric is the judge. If it improved, keep. If not, reset.
• Don't go off-script — if you want to ALSO regenerate backlinks, ALSO run /verify, ALSO update docs/INDEX.md, that's scope creep. One loop, one metric, one category.
