AnthropicSkillstatus
Case status summary by audience — client-facing (plain language), internal (for the professor), or court-ready (formal caption format per local rules). Same facts, different framing and depth. Use when a student needs to update the client, brief the professor, or prepare a court status report.
Also in 3 projects that use this
GitHubSkillrefactor
Surgical code refactoring to improve maintainability without changing behavior. Covers extracting functions, renaming variables, breaking down god functions, improving type safety, eliminating code smells, and applying design patterns. Less drastic than repo-rebuilder; use for gradual improvements.
Also in 3 projects that use this
DockerSkillreview-pr
Review one or more incoming Docker documentation pull requests as a maintainer. Independently validate technical claims, assess editorial fit and information architecture, choose a verdict, and draft exact inline or PR-wide feedback behind a confirmation gate. Use for requests such as "review PR 123", "is this PR correct?", "does this information belong here?", "validate this PR", or "help review backlog PRs". Do not use to maintain or fix a PR you own; use maintain-pr for that.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
4 rules. 0 are common, 1 is distinctive, and 3 are very specific to this project.
0
Common
Most of the 42 edited versions we read keep these.
1
Distinctive
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 14
Env vars are checked by NAME only: Never pull, print, or diff env VALUES — not in chat, not in a file.
- Distinctive: line 21
No matching offlocal project?
- Very specific: line 22
If a launch plan (launch_*) exists for this project, also run preflight_launch and verify_launch and fold their results into the report.
- Very specific: line 27
Check presence of each name on the deploy platform via offlocal (get_project_context, provider env getters).
“Common” is measured: kept by at least 6 in 10 of the 42 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Preflight — the last pass before a repo goes public
One run per repo. The pass is read-only on infra: it reports platform problems; fixing them (set env var, Stripe config, DNS, deploy) is a CLAUDE.md Hard Stop. Collect every needed infra fix into ONE batched go-ahead list at the end — never apply them mid-pass, never ask one at a time.
Two rules that override everything below:
- Env vars are checked by NAME only. Never pull, print, or diff env VALUES — not in chat, not in a file. Never run
vercel env pull(it has blanked.env.localon this machine twice). - Invoke the skills; don't reimplement them. impeccable, polish, and frontend-verify each carry their own protocol.
0. Aim at the right project
git statusfirst. Note uncommitted work.- offlocal is project-scoped and keeps a "selected" project between sessions. Always:
list_projects→select_projectfor THIS repo →get_project_context. Skipping this audits whatever repo was selected last. - No matching offlocal project? Say so in the report and run local-only checks.
- If a launch plan (
launch_*) exists for this project, also runpreflight_launchandverify_launchand fold their results into the report.
1. Wiring audit (read-only)
- Required var names come from
.env.example. If it is missing or stale, grepprocess.env./import.meta.env.and report the drift — that is itself a finding. - Check presence of each name on the deploy platform via offlocal (
get_project_context, provider env getters). Names only. - Stripe, when the product charges: mode must be live for launch (
get_project_contextshows it);list_stripe_products+ prices match the pricing page;list_stripe_webhookshas an enabled endpoint on the production domain. Grep the repo for hardcodedprice_/prod_IDs that point at test mode. The Stripe account is shared across products, so a purchase here fires every other product'scheckout.session.completedendpoint on the account: list the endpoints and confirm each one's handler guards by its own price ids (2026-09-03: the first live Off Localhost sale minted a declick license and a CallClaw client row).
2. Design pass (bounded)
- Invoke
impeccable:impeccableaudit on the main surfaces. Fix criticals and quick cosmetic wins in this pass; structural redesigns get FLAGGED for Wes, not built — launch eve is not redesign time. - Then invoke
polishfor the final micro-detail pass.
3. Verify
- Invoke
frontend-verifyover/, the pricing page, and every route the design pass touched. - Build gates from
package.json: install, lint, typecheck, test, build — read the output. - Live check: fetch the production URL. HTTPS, real title, OG meta, favicon.
- Sharecard, as the crawler sees it:
curl -sI -A "Twitterbot/1.0" <og:image url>returns 200 image/png at 1200x630;twitter:cardissummary_large_imageandtwitter:imagenames the image; robots.txt has no prefix that swallows the image (Disallow: /ogblocks/og.png); the image URL carries?v=Nbumped since the last render. Then paste the URL into a real X or Slack composer and look at the card. Any miss is a FAIL on theverifyline, and a code fix. - SEO floor:
/sitemap.xml,/robots.txt(with a Sitemap line, disallowing dashboard/api/thanks),/llms.txtall return 200 with real content; every indexable page has its own title + meta description; noindex pages carryrobots: { index: false }. Missing any of these is a FAIL on theverifyline, and a code fix, not an infra one. - Search registration: Google Search Console property verified with the sitemap submitted and the home URL inspected, Bing Webmaster Tools imported from Search Console, the host's analytics enabled with its tag live on every page. Do it in this pass through the browser tools, following
references/search-registration.md; only the Bing sign-in is handed to Wes. Reported on its ownsearchline below.
4. Report (exact shape, then stop)
PREFLIGHT: <repo> — <date>
[PASS|FAIL] env missing on platform: NONE | NAME_A, NAME_B
[PASS|FAIL] stripe mode=<live|test|n/a>, webhook=<prod domain|MISSING>, products=<n>
[PASS|FAIL] design impeccable: <n> fixed, <n> flagged; polish done
[PASS|FAIL] verify frontend-verify: <n>/<n> routes pass
[PASS|FAIL] build lint/typecheck/test/build output read
[PASS|FAIL] search gsc=<verified|MISSING> sitemap=<submitted|MISSING> bing=<imported|PENDING WES> analytics=<vercel|posthog|MISSING>
VERDICT: LAUNCH READY | BLOCKED: <one line per blocker>
NEEDS GO-AHEAD (batched): <infra fixes with exact action + rollback | none>Code fixes from the pass are committed via /ship after the report. Announcing is a separate skill: offer /launch only once the verdict is LAUNCH READY.
Red flags — stop and correct
- An env VALUE anywhere in your output → redact, switch to names.
- About to set an env var, touch Stripe/DNS, or deploy mid-pass → Hard Stop; it goes in the batched list.
- impeccable proposing a rebuild → flag it, don't build it.
- Writing VERDICT without having read the frontend-verify table and build output → not a verdict, run them.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
