Docs Review

docs-review

A generic docs auditor: reads each markdown file in docs/, identifies what source code it documents (by scanning file paths, flag names, command syntax, state names, config examples), then cross-references those claims against actual source files. Reports drift (doc says X, code does Y) with file:line evidence.

When to Use

• Periodically (weekly cron) to catch docs that fall behind code changes
• Before a release to ensure docs are accurate against the current codebase
• After refactoring commands, config schemas, or state machines
• Skip if docs/ does not exist — exit cleanly with a note

When NOT to Use

• Pure narrative sections with no verifiable source claims (history, philosophy, rationale)
• Docs for external APIs you don't own — you can't grep their source
• Formatting or style reviews — only semantic drift matters

Invocation

/docs-review
/docs-review --since 2026-04-01
/docs-review --output reports/docs-drift.md

Workflow

Step 1: Discover docs

ls docs/*.md 2>/dev/null || echo "No docs/ directory found"

If no docs/ directory exists, exit cleanly:

No docs/ directory found — nothing to review.
Exit 0.

If --since <date> was provided, narrow the file list:

git log --since="<date>" --name-only --pretty=format: -- docs/*.md | sort -u | grep '\.md$'

If this returns nothing, exit cleanly:

No docs files modified since <date> — nothing to review.
Exit 0.

Step 2: For each doc file, extract verifiable claims

Read each doc and extract claims that can be cross-referenced against source code:

Skip sections that are clearly non-verifiable: intro prose, motivation, design rationale, future plans.

Step 3: Cross-reference each claim against source

Command flags — search shell scripts and code files:

grep -rn "\-\-flag-name" --include="*.sh" --include="*.mjs" --include="*.js" --include="*.py" --include="*.ts" .

If no match: DRIFT candidate. Confirm the flag truly doesn't exist before reporting.

State names — search executor/dispatcher scripts for the state strings:

grep -rn "pending\|running\|done\|failed" --include="*.sh" --include="*.js" --include="*.py" .

Cross-check the exact transition order documented against what the code enforces.

Config keys — grep the relevant config files and any code that reads them:

grep -rn "max_concurrent\|not_before" --include="*.sh" --include="*.yml" --include="*.json" --include="*.js" .

File paths — check they exist:

[ -f "path/to/file" ] && echo "EXISTS" || echo "MISSING"

Or for directories:

[ -d "path/to/dir" ] && echo "EXISTS" || echo "MISSING"

Exit codes — grep the relevant scripts for the actual exit calls:

grep -n "exit [0-9]" script.sh

Example invocations — verify the binary/script exists and the flags used in the example are real:

[ -x "./dispatch.sh" ] && echo "executable exists" || echo "MISSING"
grep -n "\-\-agent" dispatch.sh

Step 4: Format findings

For each drift item found:

DRIFT: docs/dispatch.md:42 claims "--context" flag exists
  Source check: grep "--context" *.sh → not found
  Evidence: no match in dispatch.sh, executor.sh, or any .sh file

For each verified claim:

OK: docs/dispatch.md:15 "--group-id" → dispatch.sh:47 (confirmed)

For each skipped claim (non-verifiable):

SKIP: docs/overview.md:1-10 — intro prose, no verifiable source claims

Step 5: Summary

After processing all files, emit:

=== docs-review summary ===
Docs reviewed: N files
Claims checked: M
  OK:    X verified
  DRIFT: Y items
  SKIP:  Z non-verifiable

Drift items:
  - docs/dispatch.md:42 — "--context" flag not found in source
  - docs/executor.md:18 — state "queued" not found; code uses "pending"

Exit 0 if no drift found, exit 1 if any drift items exist.

If --output <path> was provided, write the full findings (all OK/DRIFT/SKIP lines + summary) to that file.

Checks to Perform

The six canonical checks — apply all of them:

Link validity check — extract and verify all internal markdown links:

# Extract internal links (not http/https)
grep -oP '\[.*?\]\(\K[^)]+(?=\))' docs/file.md | grep -v '^https\?://' | while read link; do
  [ -f "$link" ] || [ -d "$link" ] && echo "OK: $link" || echo "DRIFT: broken link → $link"
done

Anti-Patterns

Do NOT do these:

• Fabricate drift — only report what you actually verified with grep/read. If grep returns results but you can't find the exact claim, mark SKIP not DRIFT.
• Skip docs that look correct — every doc gets checked; intuition is not evidence.
• Fail on formatting — wrong indentation, different phrasing of correct content: not drift.
• Report style issues — "this example could be clearer" is not drift.
• Check external API docs — if the doc describes a third-party API, skip it.
• Over-grep — match the exact flag name, not a substring. --group should not match --group-id.

Adding to a Team Cron

To run docs-review automatically on a schedule:

# In crew.yml, under the team's cron section:
cron:
  - schedule: "0 6 * * 1"  # Weekly Monday 6am UTC
    task: "Run docs-review: check docs/ for drift against code"

For repos with active doc changes, use a daily schedule:

cron:
  - schedule: "0 7 * * *"  # Daily 7am UTC
    task: "Run docs-review --since yesterday: check docs/ for overnight drift"
