readme-check

name: readme-check description: > Audits all README.md files in the repo for staleness after significant code changes and auto-fixes drifted tables. Discovers READMEs dynamically. Skips automatically when fewer than 50 C# files changed in recent history. Triggers on: check readme, readme stale, is readme up to date, readme check, readme accuracy, readme outdated, update readme. allowed-tools: Read, Glob, Grep, Bash, Edit flags: --skip-threshold: Skip Step 1 (threshold check) and proceed directly to the audit. Use when the caller (e.g. /yeet) has already computed the count and confirmed it meets the threshold.

Audits all README.md files for staleness after significant code changes. Only triggers a review when the change volume warrants it.

README discovery

Discover all READMEs dynamically in Step 2. Common locations:

Step 1: Check threshold

Skip this step if invoked with --skip-threshold — proceed directly to Step 2.

Count .cs file changes in the last 30 commits:

scripts/status.sh --history 30

If fewer than 50 .cs files changed, report "README check skipped — below threshold" and stop.

Step 2: Discover READMEs

scripts/solution-inventory.sh --readmes

Verify the inventory above is still complete. If a new README exists, flag it.

Step 3: Audit each README

Root README.md

1. Read README.md
2. Cross-reference project tables against scripts/solution-inventory.sh --json (solution + projects[].path)
3. Cross-reference script table against scripts/help.sh output
4. Check .NET version against Directory.Build.props or the global.json SDK pin (scripts/sdk-version.sh)
5. Verify lode links resolve to existing files

scripts/README.md

1. Run scripts/readme-table-diff.sh --json — deterministic set-diff of documented vs. on-disk scripts. drift: false means the script tables (public + internal/) are in sync; act only on a non-empty missing_from_readme / extra_in_readme.
2. Read scripts/README.md and check that flags documented match actual script --help or argument parsing

src/*/README.md (packable projects)

For each packable project from scripts/solution-inventory.sh --json (projects[].packable == true) that has a README:

1. Read the README
2. If the project contains analyzers, run scripts/analyzer-stats.sh --json to get all diagnostic IDs and code fix provider coverage — every rule must appear in the rule table
3. Cross-reference the diagnostic_ids against fix providers from analyzer-stats.sh output — the "Code Fix" column must be Yes for rules that have a provider, No otherwise
4. Check <Version> in the .csproj matches any installation snippet in the README
5. Verify rule categories and titles match the DiagnosticDescriptor fields

Step 4: Report

• If no drift found across any README — report "README audit: PASS — no drift" and stop
• If drift found — present all findings grouped by file, with specific proposed edits

Step 5: Apply fixes

1. Apply all fixes using the Edit tool
2. Leave staging and committing to the caller (e.g., /yeet stages and commits as one unit)

Rules

• Audit all READMEs, not just root — every README in the inventory must be checked
• Skip if below threshold — don't waste time auditing after minor changes
• No agent spawn — audit directly using Read + Glob + Grep
• Auto-fix drift — apply corrections directly; only ask for approval on structural changes
• Don't restructure — match the existing style and organization of each README
• Analyzer README is NuGet-facing — accuracy is critical; verify every rule ID, title, category, and code fix flag
