Carmack Philosophy
- Evidence over assumptions
- Minimal reproduction cases
- Debugger over print statements
- Surgical fixes, not rewrites
- Closed-loop verification
- Know what NOT to build — use existing tools over custom implementations
- Ship, measure, iterate — perfection is the enemy of validation
Model-the-Real-System Gate (MANDATORY — 2026-07-03)
Before you write, label, or estimate anything that describes a real system — a device's capabilities, an API's config, an equipment/hardware layout, a rate/limit/tier, "what channel carries X", any physical or account fact the code then models — you MUST read that system's OWN state live first. Never infer the ground truth from a name, a code comment, a variable label, a prior "Verified" note, a UI string, or plausibility. This is the Ground-Truth Standard applied to modeling, not just to final reports: the model is a claim, and a claim isn't a fact until fetched from the primary source now.
The cheapest live probe almost always exists and almost always fits in one call:
- A device/integration exposes a capability/settings object — read it (thermostat
settings.hasHeatPump/hasBoiler/hasElectric/heatStages, Stripe account caps, a printer's IPP attributes, a DB's information_schema, a feature-flag payload). One GET refutes a whole fabricated premise.
- "Which channel/field carries the real data" is answerable by pulling a window that actually contains the event and summing per-field (e.g. a winter runtimeReport to see heat lands on
auxHeat1, not compHeat1). Don't assume the obvious-named field is the populated one.
- If the live value can't be fetched right now (stale token, no creds, offline), say so plainly and mark the model as assumed pending verification — do NOT assert it as fact, and default to the option that is wrong-safe (charges nothing you can't prove, hides no cost) while flagging the assumption in the UI/copy.
Tripwire: if the code's model rests on an equipment/config premise (a // heat pump + aux backup comment, a auxKw var, an "attisPro heat pump" identity string) and you have NOT this session read the system's own fields that would confirm it — STOP and read them before touching the model. Reference incident (2026-07-03, thermostat-dashboard): the entire cost model + savings tips assumed a heat pump with resistance "aux" backup (a 2.3×-cost-of-aux narrative, a phantom compHeat1×coolKw heating term). One live GET /1/thermostat?includeSettings returned hasHeatPump=false, hasBoiler=true, hasElectric=false — the heat is a gas boiler, so heating isn't even on the electric bill the dashboard estimates. Every "savings" number for heating was fiction. The refutation cost one API call that should have run before the model was ever written.
No-Lie Final Report Gate (MANDATORY — 2026-05-18)
Before returning any "done" summary to the user, run the No-Lie Verification Protocol from ~/.claude/skills/shared/no-lie-verification.md — all five checks. The most common failure mode of this agent is reporting the state of its own actions instead of the state of the world after those actions. The protocol blocks: stale-world-state lying, post-rebase build silently broken, scope-myopia, and numeric claims without proof.
Hard requirements before declaring done:
git fetch origin && git status — confirm main hasn't moved out from under you. If it has, rebase + re-test.
- For every PR you opened:
gh pr view <N> --json mergeable,mergeStateStatus — must be MERGEABLE, not CONFLICTING.
- Re-grep the original symptom across the whole repo — proves "fixed all instances", not "fixed the ones I noticed".
- Every numeric/factual claim in the final report cites its proof source inline (SQL query / curl output / file:line / build exit code + timestamp).
- If the changeset modifies user-facing copy with numbers, the final report includes a cache-busted curl against the live URL proving the new numbers render.
- Skill/config backup (user rule 2026-06-12): if this session edited ANY file under
~/.claude/skills/, ~/.claude/agents/, ~/.claude/CLAUDE.md, or ~/.claude/settings.json, run ~/claude-code-boilerplate/scripts/backup-claude-config.sh and confirm its output shows a pushed commit URL. The SessionStart auto-backup only captures the PREVIOUS session's state — mid-session skill improvements are untracked on GitHub until this runs. (Repo work is separate: every repo commit must already be pushed — git log @{u}..HEAD empty.)
Forbidden in final reports without proof: "verified", "confirmed", "all clean", "shipped", "deployed successfully", "PR opened ready to merge", any specific count/percentage.
Reference incident (2026-05-18, hospital-ledger PR #2): Agent reported "PR opened, branch tracking origin, build clean, all numbers verified" — reality was PR CONFLICTING (main moved during the session), final summary cited "3,699 hospitals" with proof only in a scratchpad not surfaced to the user, no live-URL re-check was attempted. /ship caught it; this gate now catches it inside /carmack.
Context Quality (how to see the codebase clearly)
The sequence matters more than any single tool choice.
Default investigation loop: Grep to find → Read to understand. Grep returns file:line:content output that feeds directly into Read(file, offset=line-10, limit=20) for surrounding context. Don't break this loop by routing through Bash.
Use Read — not Bash — for:
- Images, PDFs, notebooks —
Read renders visually so Claude actually sees the content. cat screenshot.png returns binary garbage; cat file.pdf returns gibberish. Huge loss on UI debugging, design comps, inspecting anything you just captured.
- Any file you plan to Edit —
Read registers the file for safe edits. Without it, Edit fails with "file has not been read yet" and you waste a retry.
- Files where line numbers matter —
Read prefixes them consistently for follow-up edits.
Use Bash — freely — for:
- Git archaeology:
git log -p, git blame, git diff A..B — often the highest-signal context in a debug session. No native equivalent.
- Executing code for evidence:
node, python -c, curl, timeout 120 npx vitest run specific-test. Evidence beats speculation.
- Compound pipelines: anything involving
sort/uniq/wc/awk/xargs. Example: grep -rn "TODO" --include="*.ts" | grep -v test | sort | uniq -c | sort -rn for a ranked frequency table.
- Running CLI tools:
osgrep, qmd, bd, gh, wrangler, git, npm.
Don't use Bash as a Read substitute (cat, head, tail, sed -n '50,70p', less). You lose multimodal rendering, file-read tracking, and clean line-numbered output.
Don't use Bash as a Grep substitute for simple pattern searches. Native Grep returns structured output that feeds straight into the next Read call with offset/limit. Reserve grep -rn | pipeline for compound analysis Grep can't express.
Mode Detection
Determine mode from the user's request, then read ONLY the relevant reference files before launching the agent. This keeps context lean.
| User Intent Pattern | Mode | Reference Files to Read |
|---|
iOS, iPhone/iPad app, Xcode, simulator, Swift/SwiftUI, Capacitor shell, app crash/.ips, TestFlight (dev questions), xcodebuild, App Store compliance, app screenshots/ASO, Clerk/Apple/Google social sign-in failing in a Capacitor app (authorization_invalid / native_api_disabled / origin_authorization_headers_conflict / oauth_token_apple / "native social login won't work in the app"), OR a passkey/WebAuthn ceremony failing in a Capacitor webview ("passkey registration was cancelled or timed out", webcredentials, associated domains, AASA 404) | ios — invoke the /ios skill (~/.claude/skills/ios/SKILL.md): THE Apple-side counterpart of /carmack. It routes to xcodebuildmcp (build_run_sim loop), axiom agents (crash-analyzer, build-fixer, performance-profiler), greenlight, axe webview driving, the /serve-sim skill (simulator MJPEG stream = agent eyes, normalized-coord taps, :3100/ax a11y tree, camera injection, permissions, CA-debug overlays — npx serve-sim --detach -q), and the granular asc/store-asset skills. Web-layer bugs inside a Capacitor app come BACK here (/carmack patterns — it's web code). iOS RELEASE work (archive/TestFlight/submit/OTA publish) routes to /ship Phase 4.7. In-webview auth/credential ceremonies all fail with a GENERIC error until the right app↔domain binding exists — see /ios trap #12's binding matrix (probe FIRST): social-OAuth Apple → trap #4 (allowNavigation); Google → blocked by policy, hide it; clerk-js scheme → allowedRedirectProtocols; passkey "cancelled or timed out" → AASA file + Associated Domains entitlement (improvebayarea dadfdf3). Don't debug the JS ceremony before the 30-sec binding probe. | /ios skill |

DBI complaint reported as validation error but the city actually has it, third-party form submit ok=false but agency confirms via mail / DataSF, form echoed back on success, "DBI re-rendered the form (validation rejected the submission)" appears for every submission, every IBA-submitted DBI complaint fails, success-detection heuristic matches both success AND failure pages, complaintNumber: undefined but submission worked, parser returns ok=false on HTTP 200, lblError success-vs-failure span, signal-extraction tests use synthetic HTML, ASP.NET WebForms / Verint / dform / aspx replay false-negative on success | debug (Pattern #23) — capture real success + real failure responses to src/__fixtures__/<integration>/, write a tools/repro/<integration>-probe.{sh,mjs} script, diff the two fixtures to find an anchored distinguishing feature (DOM id, JSON field — NOT a substring present in both), rewrite the detector to extract that feature, add tests that readFileSync the captured fixtures.

YouTube "Error 153" / "Video player configuration error", embed shows a gray panel, Vimeo/Spotify/SoundCloud embed won't load, "video plays on youtube.com but not on my site", embed broke after adding security headers / secureHeaders(), rendered href contains prose, bare URLs render as dead text | debug (Pattern #27) — the page sends Referrer-Policy: no-referrer (Hono secureHeaders() default); YouTube has rejected Referer-less embeds since late 2025. It is NOT CSP and NOT the video. Two-command probe before any fix: curl -sI https://<site>/ | grep -i referrer-policy and the oembed status for the video id. Fix = referrerpolicy="strict-origin-when-cross-origin" on the iframe (never weaken the global header). Verify on the DEPLOYED artifact + a browser screenshot — hono/jsx vs React attribute casing silently drops it, and Worker propagation takes >30s so an immediate curl false-negatives. Then sweep the repo for the siblings: hrefs containing whitespace, un-linkified bare URLs, malformed URL literals. | ~/.claude/skills/debug/references/csp-cache-patterns.md (Pattern 27) |
| provider swap, replace Resend/Auth0/Stripe/S3 with X, migrate email/auth/payments provider, remove the old SDK, delete the old API key, "switch us completely to X" | provider-migration — run the 7-item checklist BEFORE declaring done: one seam, discriminated-union result, zero guards naming the old env vars, legacy ids discriminated by shape, emulator rules re-derived from the live API, every integration point actually removed, cron blast radius measured against PROD data. Report cost honestly (a swap often saves $0). | ~/.claude/skills/shared/provider-migration-safety.md |

third-party submit "worked" (200 + id, no error) but never went live / never got a public number / openedAt: null / publicId: null; guest/anon create silently dead-ends; A/B-tested a flag or category and the symptom stayed IDENTICAL; "is it the payload or the account/identity"; freshly-minted guest token; prove which backend gives instant IDs | debug (#30) — a sync 200+id is pending, not done: gate success on the async lifecycle transition (public number/opened), polled, vs a known-good baseline. Symptom byte-identical across payload edits ⇒ stop editing the request, the ACTOR/identity you held constant is the variable — re-run the SAME payload under a known-good established identity first.

NEVER "fix" a block with SOCKET_CLI_ACCEPT_RISKS=1 — that's a blanket, invisible, permanent override; use the scoped ~/tools/npm-real and leave the scanner armed. Persist a token with env -u SOCKET_CLI_API_TOKEN socket config set apiToken <tok> — the env -u is mandatory: with the env var exported, config set returns OK and writes nothing (read-only mode, disclosed only in config list).

This is distinct from the reactive instrument-on-build / instrument-on-fix rule in Hard Rules (which fires automatically while building/fixing) — this mode is when the user explicitly wants a log assessment pass over a window of real logs.

Additional context (load when applicable):
- For ANY new-site build, or any "convert/remake to Hono" / Hono SSR / React-SPA → Hono work (feature, plan, OR deploy mode): load the
/hono skill (~/.claude/skills/hono/SKILL.md) and the relevant references/*.md. It is the source of truth for hono/jsx (server SSR) vs hono/jsx/dom (interactive islands), the dual client/server Vite build on Cloudflare Workers, and the page-by-page SPA→Hono migration (convert one route at a time, curl each SSR page, keep the build green). Don't invent Hono middleware/hook names from memory — the skill's references are verified against hono.dev and tell you what actually exists.
- If working in an AIVA project (cwd contains "aiva" or project references example.com): also read
aiva-guidelines.md — and note AIVA ships an iOS Capacitor surface from the same repo (~/AIVA-Frontend/docs/mobile-ota.md): web changes are OTA-synced to the app by ship.sh, so client-code changes must respect the app invariants (native fetch shim, isNativeApp() webview-detector short-circuit, notifyAppReady).
- For ANY iOS/macOS app work (Xcode project, simulator, Swift, Capacitor shell): load the
/ios skill as the phase playbook — it owns the build/run/debug loop (xcodebuildmcp), crash + perf triage (axiom agents), webview driving (axe), and compliance scanning; /carmack supplies the investigation discipline on top.
- For all modes except research/browser: also read
preflight-checks.md
- For ALL modes: also read
~/.claude/skills/shared/ant-verification-protocol.md (ant-level quality gates)
- For ALL modes: also read
~/.claude/skills/shared/tool-error-recovery.md (catalog of tool errors and recovery patterns — consult on any tool failure, and APPEND a new entry whenever you hit a novel one)
- For ALL modes: run
~/.claude/skills/carmack/tools/scan-tool-errors.sh once when invoked. If it prints novel patterns, read ~/.claude/tool-errors-pending.md, classify each, append entries to tool-error-recovery.md, then run the scanner with --clear to archive the log. This keeps the error catalog self-updating.
- For ANY infra/config/plugin/service work: always read
blind-spots.md — covers schema-validation-before-restart, self-upgrade traps, "gateway started ≠ working", compaction telemetry, adjacent-system breakage, guardrail-alert-vs-enforcement patterns learned from real incidents
- For ANY change to an HTTP route handler, a
scheduled()/cron body, a cache (read or write/warm), or a SQL/D1 query (in feature, debug, review, OR deploy mode): run the Hot-Path Data-Volume & Cache-Topology Audit (section in debug-patterns.md). Three quick checks: (1) every query that runs before the response must be bounded (LIMIT/indexed range/fixed-cardinality GROUP BY) or cache-served — measure any COUNT(*)/SUM(CASE...)/whole-partition aggregate over WHERE <partition_key>=? with npx wrangler d1 execute <DB> --remote --json --command "..." → meta.rows_read; >~100k on a per-request path is a bug, even if it predates your change (fix-all rule). (2) For every readCached*/KV.get/caches.match, grep for the writer of that exact key; for every prewarm*/cache-warmer, grep for what reads those keys — a reader with no writer (or a warmer warming a different key-shape than the route reads) is a latent perf bug. (3) WHERE ts >= now() - <interval> against a lagged source returns empty — anchor on MAX(ts). This is the lesson from the 2026-05-12 improvebayarea incident (coverageForCity scanned 8.6M rows on every request; the cron warmed oak311:open_data:... but the route read agg:...; the 24h window was now()-anchored against DataSF's 1-2-day-lagged data) — three round-trips that this audit collapses to one.
- For ANY new subsystem build OR any bug fix (feature, debug, OR review mode): load
~/.claude/skills/shared/observability-instrumentation.md and apply both behaviors before declaring done — instrument-on-build (structured logs at external calls / catch branches / state transitions / the branch-deciding input — boundaries and decision points, not everywhere; redact secrets/PII) and instrument-on-fix (add the one attribute/message that would have named this bug in 30s). Rewrite ambiguous errors to actionable (attempted + actual values + likely cause/branch + disambiguation); reduce noise by downgrading level, never deleting. The proactive, scheduled counterpart is the /log-hygiene skill (assess last-24h logs on a cadence).
- For Clerk/auth cutovers on Cloudflare Workers: verify both provider state and effective Worker bindings.
clerk env pull is not enough; dry-run Wrangler and live HTML must prove no pk_test, sk_test, or .accounts.dev.
- For external city form integrations: a 500 after category change may be category/form-specific, not global auth/photo failure. Reproduce against the failing category and a known-good category, then add fallback plus regression coverage.
- For ANY production-deployed site work (not just security mode): also load
~/.claude/skills/shared/site-security-defaults.md — the 12-item baseline catches gaps Cloudflare Security Center alerts on, with copy-paste auto-fix recipes for Workers / Next.js / static. Skip only when working purely on internal CLI/non-HTTP code.
- For ANY npm/Node project, OR any "fix the Dependabot/security page / npm audit" request (debug, review, deploy, OR infra mode): load
~/.claude/skills/shared/dependency-audit.md and run its 7-step protocol. Traps it encodes (each bit us once): Dependabot and npm audit surface DIFFERENT vulns — run BOTH and fix the union; every sub-app manifest has its own lockfile (find . -name package-lock.json -not -path '*/node_modules/*' — scan all); an existing override floor can itself be vulnerable (ws ^8.20.1 was still <8.21.0); a blanket override across majors breaks non-vulnerable consumers — SCOPE it to the parent ("replace": { "minimatch": "^3.1.4" }) and confirm glob's v8/v10 stay put; verify the patched version is published (npm view <pkg>@<v> version) before writing it; npm audit fix --force will downgrade a major runtime dep — never run it blind. Verify build with the project's REAL build (Workers → wrangler deploy --dry-run, lib → tsc --noEmit) + one vitest run. Reference: 2026-06-15 improvebayarea (12 alerts + ws/vite, PR #5).
- For ANY site that renders external links (help pages, resource lists, footers, "official forms" links): before declaring done, run
~/tools/linkcheck.sh <repo> to prove every external href resolves to HTTP 200. It curls each link and, on any non-200, re-tests via the live :9222 Chrome — so a real 404/410 BLOCKS and gets the URL fixed, while a government/WAF bot-block of curl (403/000 but 200 in a browser) is correctly passed. Never trust a "URLs are used EXACTLY as provided — do not alter" comment — that exact comment guarded a malformed 403 POA link on the NYIA portal /help (2026-06-05). Verify, don't assume. Pairs with /ship Phase 1.45d.
- For ANY third-party integration work where the proposed fix involves a UX downgrade (handoff, redirect, manual step, "for safety"): always load
~/.claude/skills/shared/upstream-protocol-investigation.md and run Steps 1–3 (read upstream's primary client, capture real network traffic, inspect rendered data-attributes) BEFORE shipping the downgrade. Token cost is unlimited for this. Reference incident: SF311 0b746a4 (bandaid based on a wrong "verified today" comment) → f27d1e3 (real fix from reading dform's api.js lines 462–520). Treat any "Verified YYYY-MM-DD that X can't be done" comment in our codebase as a hypothesis to re-verify, not a fact.
- For ANY change to a React component that renders fetched/API data, ANY backend handler whose JSON shape the frontend destructures, OR ANY admin/dashboard/detail-page audit (feature, debug, OR review mode): always load
~/.claude/skills/shared/undefined-null-render-safety.md and run its 9-pattern undefined/null-render sweep (null-gate-hides-UI, unguarded property access, .map/string/Date on possibly-undefined, JSON.parse, raw-undefined render, missing loading/empty states, backend omits a field) + the live DOM check (drive the logged-in :9222 Chrome, grep document.body.innerText for rendered undefined/NaN/Invalid Date/[object Object] and capture console TypeErrors). Fix every real instance in the same pass (fix-all). TypeScript does NOT catch these when the response is typed any/unknown/Record<string, unknown>. Reference incident: 2026-06-01 — AIVA shipped four instances (admin clients LIMIT-truncation, MAX(NULL) sort burial, Dashboard 20-of-457 docs, the isTest !== null toggle that silently vanished); codified so the next render-data change catches all nine in one pass.
- For ANY TypeScript authored or reviewed (feature, debug, OR review mode): load
~/.claude/skills/shared/anti-slop-typescript.md and run ~/.claude/skills/carmack/tools/detect-ts-slop.sh [path|--diff <base>]. Never default to a generic isRecord/isObject guard or a blanket as any/as unknown as T — define a named type, a discriminated union, or a Zod schema (type X = z.infer<typeof Schema>) at the trust boundary, and write a targeted predicate only as a last resort. Fix every detector hit in the same pass (fix-all). This is the runtime-guard sibling of the No-Suppression Rule and the upstream cause of the undefined/null-render bug class.
- For ANY watcher / cron / poller / webhook / diff-against-state code (debug, review, OR feature mode): always load
~/.claude/skills/shared/signal-logic-audit.md and run its 12-pattern checklist against the changed code. Grep each pattern's smell, classify matches as real-instance vs deliberate-and-correct, and fix every real instance in the same pass (fix-all rule). The 12 patterns: pre-finalized-as-terminal, set-based-dedup-misses-flip-back, deadline-without-expiry-probe, first-seen-ID-ignores-status, no-allowlist-for-benign-novel, upstream-permissive-needs-business-rules, opaque-IDs-as-keys, forward-only-diff, ID-only-ignores-version, population-wide-as-individual, unbounded-state-no-TTL, upstream-permissive-needs-policy-gate. Reference incident: 2026-05-13 — 11 bugs fixed in ~/tools/va-watchers/va-watch.py, each one an instance of one of these patterns; codified into the catalog so the next watcher author / reviewer / debugger catches all 12 in one pass instead of three round-trips.
- For AIVA / Cloudflare production-code audits: prove you are editing the Worker/static-assets repo that actually routes to
example.com before fixing anything. Audit findings are not handled until the deployed code path is fixed, a deterministic guard/test exists where practical, and the live production response proves the bad fingerprint is gone.
- For ClawPatch/Codex release-gate findings: convert one-off audit output into repo guardrails: same TypeScript mode as production build (
tsc -b for project references), full tests/prod integration in predeploy, real a11y gate, asset guard that scans every generated HTML/JS asset and fails closed, local Worker integration with owned readiness/cleanup, peer-dependency health, and bounded npm overrides.
- For Worker secret migrations: plaintext key/token/password values in
wrangler.json vars are production blockers. Carmack may prepare the code/config patch, but deployment belongs to /ship; if Cloudflare reports the binding name is already in use, the ship workflow must remove the plaintext var from config, deploy without --keep-vars, immediately wrangler secret put, then verify wrangler secret list reports secret_text.

Hard Rules (NEVER VIOLATE)
Deployment Prohibition — never CAUSE a production deploy (UPDATED 2026-06-25)
The rule is NOT "never touch main" — it is: /carmack must never cause code to reach production. Carmack builds, implements, tests, commits, and MAY merge/push to main on repos that do NOT auto-deploy on a main push. It must NEVER run a deploy command, NEVER invoke /ship, NEVER change prod secrets, and NEVER push to main on a repo where that push auto-deploys to production. This outranks any "/ship phase," any other instruction, and the model's own judgment.
MANDATORY — run Auto-Deploy Detection (below) BEFORE any push/merge to main:
- No auto-deploy detected → merging/pushing to
main is ALLOWED. First rebase onto current origin/main and push a clean current-base commit — NEVER push a stale-base tree (a worktree behind origin/main pushed to main reverts everyone's commits; see 2026-06-25 below).
- Auto-deploy detected, OR you cannot rule it out → DO NOT push to
main. Push the feature branch only, then DISPLAY the detected mechanism to the user (which CI/integration + which branch, e.g. "⚠️ Cloudflare Workers Builds is Git-connected to this repo on main — pushing to main WILL auto-deploy to production") and STOP for explicit authorization. That main push would deploy to prod — the prohibited action.
Always-BLOCKED (never run, regardless of auto-deploy status): wrangler deploy / versions deploy / pages deploy, wrangler secret put/delete (prod), npm/bun/pnpm/yarn run deploy, vercel --prod, netlify deploy --prod, the /ship skill / ship.sh, force-push to a shared branch, gh pr merge / gh pr close into main, or any command that explicitly pushes to production.
Commit on the RIGHT branch (MANDATORY — 2026-07-21): before git commit, run git branch --show-current. A hotfix / config change / anything unrelated to an in-progress feature belongs on main — do NOT let it land on whatever branch happens to be checked out. Committing onto a long-divergent feature branch strands the change (it can't ship without dragging the branch's other commits). Enforced by the PreToolUse hook pre-bash-commit-branch-guard.sh, which BLOCKs a commit on a non-main branch that is behind origin/main or ≥6 ahead (override CLAUDE_ALLOW_BRANCH_COMMIT=1 when the branch IS intended). Reference incident: a robots.txt hotfix committed onto feat/explain-gap-and-close-it (11 ahead of main) → needed a cherry-pick + full branch reconciliation to ship.
Auto-Deploy Detection (run before any main push — if ambiguous, assume YES = don't push, display, ask)
A repo auto-deploys on a main push if ANY of these holds:
- GitHub Actions — read
origin/main workflows, NOT the local checkout (a behind worktree shows stale/deleted workflows — this misled the 2026-06-25 session, which grepped a 375-behind tree). Broad pattern (must catch cloudflare/wrangler-action/pages-action, which contain no literal "wrangler deploy"):
git fetch -q origin; for f in $(git ls-tree -r --name-only origin/main .github/workflows/); do git show "origin/main:$f" | grep -qiE 'wrangler-action|pages-action|wrangler (deploy|pages)|CLOUDFLARE_API_TOKEN|command:\s*(deploy|pages)|run deploy|vercel|netlify deploy|actions/deploy-pages' && echo "$f"; done
then confirm a hit's on:/branches: includes main. Empirical cross-check (most reliable): gh workflow list --repo <o/r> and gh run list --repo <o/r> --limit 10 — did a deploy run actually fire on a recent main push? (A workflow_run: ["Deploy"] reference can be orphaned — confirm the workflow is registered AND runs.)
- Cloudflare Pages / Workers Builds Git integration — NOT visible in the repo; query the CF API with
~/.cloudflared/cf-global-api-key.json. Match the prod DOMAIN, not just a project name (exampleapp had two *.pages.dev projects named aiva* that were red herrings — not Git-connected, wrong domain). Pages: GET /accounts/{acct}/pages/projects/<name> → auto-deploy only if source.type is github/gitlab with a production_branch; a null source / ad_hoc trigger is NOT auto-deploy. Workers Builds: the live worker's latest version annotation workers/triggered_by is build for a Build vs version_upload for a plain wrangler deploy; builds/triggers → 404 ⇒ no Build connected.
- Vercel (
.vercel/project.json), Netlify (netlify.toml + linked site), or any connected CI (Render/Fly/Railway/Amplify) with a production-branch deploy hook.
Blind spot — state it, don't fake coverage: the checks above only find platform auto-deploy. A team can deploy main via a manual/CLI wrangler deploy or an off-platform cron/watcher the APIs can't see (this is how exampleapp actually ships — bursty version_upload deploys by the owner). So "no auto-deploy detected" means the push itself won't trigger prod — NOT that main is decoupled from prod. Treat main as deployable: only push correct, current-base code. If you can't rule out an external deployer, ASK the user rather than assert.
The /ship skill performs and DISPLAYS this same detection — see ~/.claude/skills/ship/references/pre-deploy-checks.md (Auto-Deploy Surface).
The carmack-mode-engineer SUBAGENT carries the same prohibition in its agent definition (~/.claude/agents/carmack-mode-engineer.md, top of body) — both layers must stay in sync.
Why (2026-03-26, reinforced 2026-06-23/24): Carmack first deployed via wrangler deploy without asking. Then on 2026-06-23/24 a carmack-mode-engineer subagent ran ~22 hours autonomously, deployed to prod 6+ times via wrangler deploy//ship with no authorization, deleted a prod secret, removed features the user said to keep, and merged to main — because the prohibition lived only here (skill) and not in the agent body, and was rationalized as "/ship phases." Both layers are now hardened; deploying/merging is the USER's job in the main session. Refined 2026-06-25: the blanket "never main" was relaxed to "never CAUSE a deploy." The triggering session is a cautionary tale about claiming a deploy mechanism without verifying it — the agent asserted twice (first "main doesn't deploy," then "Cloudflare Workers Builds auto-deployed it") and both were wrong. Ground-truth (CF API + gh): example.com has NO platform auto-deploy — no Deploy GH-Actions workflow, CF Pages not Git-connected, no Workers Builds trigger; the change reached prod via a manual/CLI wrangler deploy ~6 min later. Lessons baked into the detection below: (a) verify, don't assert the deploy path; (b) detection must read origin/main workflows + gh run list, not a possibly-stale local checkout; (c) platform-auto-deploy detection is necessary but NOT sufficient — a team that deploys main via CLI means "no auto-deploy detected" still implies main→prod soon by hand, so only ever push correct, current-origin/main-based code; (d) the same session nearly pushed a 375-behind worktree to main — hence the rebase requirement.
Premise-Check Before Debugging (MANDATORY — 2026-06-13)
Before you debug, optimize, or "make X work," validate that X is the RIGHT approach for this runtime/SDK/platform — against LIVE upstream docs, NOT a cached /skill note. Debugging a wrong approach thoroughly is the most expensive way to fail. Full rule: ~/.claude/skills/shared/premise-check.md.
Run the two-question gate before the first fix: (1) Is this approach valid for THIS SDK/platform? Check the upstream's current capability matrix — the browser SDK ≠ native SDK ≠ server SDK; a strategy/option/API documented under one is often absent or forbidden in another. If every doc/example for the thing you want sits under a different platform than yours, that's the answer — stop. (2) What's the cheapest probe (curl / grep the installed bundle / read the doc's "supported platforms" line) that proves it's even possible here? Do it before coding, not after the 3rd failed fix.
Mutating-symptom tripwire: if each fix changes the error instead of removing it (authorization_invalid → native_api_disabled → origin_..._conflict), halt on the 2nd mutation and re-verify the premise against live docs — you're debugging a wrong approach, not nearing done.
Docs-before-note (always): a /skill recipe, comment, memory, or prior conclusion is a HYPOTHESIS. Re-verify any load-bearing "API/SDK can/can't do X" claim against the upstream's own current docs/source before building on it; the live source wins and you fix the stale note in the same pass.
Why (2026-06-13): the Clerk-native-Apple saga — hours making oauth_token_apple work from a Capacitor webview when Clerk's docs put that strategy under Expo/RN only and clerk-js (browser SDK) can never send it (browser-forced Origin vs Native-API Authorization). A wrong /ios trap #4 note was trusted as fact; the working web-OAuth fix was a 5-minute live-doc read away. Now enforced session-wide by the SessionStart hook premise-check-session-start.sh.
Installed-Source Ground-Truth Guard (MANDATORY — 2026-06-12)
Before proposing ANY fix/config/workaround for a dependency, plugin, framework, or third-party widget, read the actually-installed source first — full protocol in ~/.claude/skills/shared/installed-source-ground-truth.md. Order: (1) node_modules/<pkg> types + JSDoc for exact option semantics; (2) the plugin's native platform implementation (ios/Sources/*.swift, android/src/**) when platform support matters — a TS type does not prove your platform implements it; (3) runtime DOM/traffic probes for third-party widgets — never patch an assumed DOM. Cite what you read (file + symbol) in the fix. Reference incident (2026-06-12): overlaysWebView was "known" to be Android-only — reading the installed StatusBarPlugin.swift proved iOS support, which was the one clean fix after three failed CSS-cascade workarounds; the contentInset JSDoc prevented shipping a fix that physically couldn't work.
Reverse-Engineering Pre-flight (MANDATORY — 2026-05-08)
Before ANY integration work where you'd reach for jadx, apktool, frida, or "I'll just import this RE'd library on disk":
-
Climb the API ladder in order:
- Rung 1: public docs (Open311, OData, vendor REST docs)
- Rung 2: unauth-probe first-party endpoints (open the real site in Chrome, DevTools→Network, capture the real form submission)
- Rung 3: RE the official thin client
- Rung 4: RE a third-party client
- Rung 5: browser automation
- Stop at the first rung that works. Document why earlier rungs didn't.
-
Before importing a found RE'd library on disk:
- Capture the official client's network traffic for the SAME operation (DevTools→Network preserve log, or mitmproxy)
- Count requests. If the library makes fewer than the real client, the library is incomplete.
null and empty-string return fields are red flags, not features. valid: true, resource_id: null means "validated, never finalized", not "async assignment, trust the doc-comment."
- Look for "post-save" / "finalize" / "complete" calls the library may have missed.
-
TOS posture preference (always):
- First-party documented public API > unauth-probe of first-party site > RE'd official client > RE'd third-party client
- Never ship production code that depends on a static API key lifted from someone else's APK if a first-party path exists.
-
A decompiled string/symbol is NOT proof of runtime use. A function name, GraphQL operation, endpoint, or channel that appears in an APK's JS bundle or strings output proves the app can reference it — never that it does at runtime. Before building or extending an integration on a found symbol, confirm the real client actually invokes it: capture live traffic (mitmproxy / CDP) and watch for it. Reference incident (2026-05-19): TicketChangeSubscription existed only as a string in the SF311 APK bundle; spotmobile_cable.ts (~2,500 lines) plus four successive bug-fix layers were spent making a WebSocket reach a /cable endpoint — then a live mitm capture of the real app proved it opens zero WebSockets and resolves the value by HTTP/2 polling. The string was capability, never usage.
-
Android-app mitm — hard-won operational notes: runtime settings put global http_proxy and the -http-proxy boot flag are both unreliable on the Android 14 emulator — apps ignore them. What works: a rooted (google_apis, not google_apis_playstore) AVD + mitmproxy in regular mode (force-stop the app so it re-reads the proxy), OR a rooted iptables transparent redirect. Android 14 moved the trust store off /system/etc/security/cacerts/ — the mitm CA must be bind-mounted into the conscrypt APEX cacerts via nsenter into zygote's mount namespace. Frida unpinning is usually still needed on top.
Reference incident: feedback_first_party_api_first.md, feedback_capture_traffic_before_extending.md. SF311 RE failure 2026-05-08 — I jumped to APK reverse-engineering, missed /api/custom post-save hooks, shipped a partial submitter; Codex went first-party + captured traffic, shipped clean. Codex's was correct.
Browser Cookies for Non-Browser Tools (curl / yt-dlp / scrape / n8n)
When code or scripts need cookies from a logged-in browser session, pick by where the session lives — do not spawn a separate browser (unbrowse / agent-browser) hoping it has the session, it won't:
| Session location | Tool | Output |
|---|
| Live REAL Chrome (fcdp-driven) | ~/tools/fcdp/fcdp raw Network.getCookies '{"urls":[…]}' | Includes session-only cookies not yet flushed to SQLite. No Keychain prompt. |
Regular Chrome (~/Library/Application Support/Google/Chrome/Default) | ~/tools/cookies-txt <url> | Reads SQLite + Keychain. Headless-safe, cron-safe. |

When porting any browser-extension behavior to a CLI, see the /decompile skill's "Browser extension" workflow (renamed from /ghidra on 2026-05-28; the skill is now a universal RE router covering APKs, IPAs, .NET, Hermes, WASM, firmware, browser extensions, etc.). Ghidra itself is the wrong tool for extensions (no compiled code), but the skill routes you to the right JS toolkit (prettier, webcrack, etc.). For ANY reverse-engineering task — decompile, disassemble, "look inside this binary/app/firmware" — invoke /decompile first; it handles tool routing.
Test Safety (CRITICAL)
Vitest fork workers leak ~5GB memory each when they hang:
- ALWAYS wrap test commands:
timeout 120 npx vitest run src/specific/test.ts 2>&1
- NEVER run full test suite (
npm test, npx vitest run with no args)
- Maximum 3 test runs per investigation phase
- Clean up:
pgrep -f vitest | xargs kill 2>/dev/null
Infrastructure Safety
- NEVER execute
terraform destroy, terraform apply -auto-approve, DROP TABLE/DATABASE, or cloud CLI delete/terminate commands
- NEVER modify .tfstate files
- ALWAYS show
terraform plan output and get approval before any apply
- Before ANY infra command: what resources are affected? Is it reversible? Could it affect unintended resources?
- Worker preview hostnames are LOCKED by default (user policy 2026-07-07) — never set
previews_enabled: true (CF API) or preview_urls: true (wrangler config), and never share a <name>.cloudflare.app URL, without an explicit same-session user "yes" (AskUserQuestion; offer the Access-gated option first — CF supports Cloudflare Access on preview URLs). Preview hostnames bypass all zone security. Hook pre-preview-lock-guard.sh blocks the attempt; after user approval, prefix CLAUDE_ALLOW_PREVIEW_PUBLIC=1. The stop hook preview-lock-stop-check.sh re-sweeps after any deploy session; /ship Phases 4.09/4.05d re-lock on every ship.
Post-Change Verification (MANDATORY — from internal VERIFICATION_AGENT pattern)
After implementing ANY code change:
- Read the changed file(s) back — verify the edit was applied correctly
- If tests exist, run them (with
timeout 120)
- If the change affects a build, run the build and confirm exit 0
- If the change is a bug fix, verify the original symptom no longer reproduces
- If the change adds/modifies TRIGGERED behavior (failover, retry, fallback chain, circuit-breaker, rate-limit cooldown, error/
catch branch, conditional cron, feature-flag gate) — induce the trigger and watch the behavior fire end-to-end on an isolated copy. "Each component works in isolation" is NOT proof the behavior fires: "the fallback is configured" ≠ "the fallback fires." Force the 429 / kill the primary / trip the breaker / feed the bad input, confirm the right downstream component served, then confirm the live instance is untouched. Don't wait for the user to ask. See ~/.claude/skills/shared/no-lie-verification.md Check 6 (reference incident: 2026-06-19 Hermes 429→DeepSeek failover wired + each hop verified but never exercised until the user prompted; a forced-429 throwaway-config test then proved it).
- Never report "done" based on the edit alone — verify the outcome with evidence
Semantic Security Review Gate — LOOP UNTIL CLEAN (MANDATORY — 2026-07-22)
Before declaring ANY implementation or fix "done", run the built-in security-review skill on the changeset and loop until it is clean. This is AI/semantic dataflow analysis (SQL injection, XSS, SSRF, auth bypass, hardcoded secrets, business-logic flaws) — the vulnerability class that grep-based checks and npm audit cannot see, and that the carmack subagent's own review passes are not a substitute for.
⚠️ OPERATIONAL (verified 2026-07-22): security-review runs against the CURRENT WORKING DIRECTORY's git repo — NO path argument; hard-fails "needs to run inside a git repository" if cwd isn't the repo, so cd <repo-root> FIRST. It reviews the COMMITTED branch diff vs the base (merge-base with origin/main) — NOT uncommitted working-tree edits (proven: unstaged changes produce an empty diff). So commit your fix before running this gate, or it reviews nothing. It returns a markdown report (file:line, severity, category, confidence 1–10) and self-filters false positives at confidence ≥8 — a "real finding" = any HIGH/MEDIUM in that report. If the Skill call returns unknown-skill (unavailable in this environment), do NOT silently pass — tell the user the semantic gate couldn't run.
The loop (do not skip, do not defer):
cd into the repo root, then invoke the security-review skill (Skill tool) on the current branch diff/changeset.
- Triage each finding: real vulnerability vs. genuine false positive.
- FIX every real finding in source, inline — obey the No-Suppression Rule (never
@ts-ignore/eslint-disable/biome-ignore/as any a finding away; refactor to remove the actual vulnerability).
- Re-invoke
security-review.
- Repeat 1–4 until it reports 0 actionable findings.
A genuine false positive is documented inline with its reason; everything else is fixed, never deferred (this composes with the Fix-All-Issues-Found Rule below). Do NOT report the work complete while a real security finding is open. Loop guard: if the same finding survives 5 fix attempts, STOP and surface it to the user with the finding + why the fix isn't landing — don't declare done past an unresolved vulnerability. The carmack subagent still NEVER deploys (Deployment Prohibition) — this gate makes the code security-clean before the user runs /ship, whose Phase 1.29 re-runs the same loop as the deploy-time backstop. Skip only for pure docs/comment/test-copy diffs with zero code change.
Fix-All-Issues-Found Rule (MANDATORY — 2026-04-12)
When an audit/review/diagnostic step surfaces issues, FIX THEM — do not only report. This overrides the "don't refactor beyond scope" global rule for issues uncovered during carmack's own investigations.
Triggers (non-exhaustive):
tsc --noEmit reports errors → fix every error, even if unrelated to the task
biome check reports lint errors or warnings → auto-fix with --fix, then resolve remaining manually
npm audit reports vulnerabilities → apply overrides and verify
- Code review uncovers bugs in adjacent code → fix them
- Security sweep finds XSS/injection risks in files you didn't edit → fix them
- Build warnings → resolve, don't ignore
Behavior:
- Enumerate every finding (count them, don't truncate)
- Fix in batches, rebuilding / re-running the diagnostic after each batch
- Loop until count reaches 0 OR a finding is genuinely not fixable (documented with reason)
- Only then report "done" — and only after re-running the diagnostic one final time to confirm 0
Escape hatches (narrow):
- If fixing would require a breaking API change or major version upgrade → create a beads issue describing the blocker and continue with the rest
- If fixing is >10x the cost of the original task → pause, report the finding, ask the user before continuing
- "Pre-existing" is NOT a valid excuse. "Unrelated to my change" is NOT a valid excuse.
Why (2026-04-12): Session ended with 93 pre-existing tsconfig.worker.json TypeScript errors merely reported, not fixed. User set this as a permanent rule: if carmack sees it, carmack fixes it.
No-Suppression Rule (MANDATORY — 2026-04-12)
NEVER use @ts-expect-error, @ts-ignore, // eslint-disable, // biome-ignore, // @ts-nocheck, or equivalent suppressions as a "fix". Suppressions hide bugs — they don't resolve them.
When a type-system complaint appears legitimate:
- Investigate the root cause — library version regression, missing generics, ambient type collision, wrong middleware signature, etc.
- Refactor to make the types line up — extract to a helper, use chain-style routing, replace a validator with inline
safeParse(), upgrade a package, or rename a conflicting type
- Only as a last resort: if all of the above genuinely cannot resolve it and the code is demonstrably safe at runtime, use a narrow type assertion (
as unknown as T) at the exact expression — NEVER a line-level suppression comment that hides all errors on that line
When a lint rule complaint appears:
- Fix the code to satisfy the rule
- If the rule is wrong for the project, disable it in config (
biome.json, .eslintrc) with a comment — not per-line suppressions
Acceptable suppressions (rare, must document why):
- Third-party type declarations that are definitively wrong — suppress with a comment citing the upstream issue URL
- Intentional runtime behavior the type-system can't model (e.g., WASM boundary) — suppress with detailed explanation
Unacceptable:
- "Hono 4.12 regression" → refactor to chain-style, switch to inline parse, or upgrade
- "Timing out on the fix" → stop and ask the user before suppressing
- "Pre-existing" suppressions in the file → remove them as you refactor
Why (2026-04-12): Carmack added 4 @ts-expect-error suppressions instead of refactoring 4 routes to drop the broken zValidator chain and use inline safeParse(). User flagged this immediately. Permanent rule.
Single-Affordance Rule for Form Controls (MANDATORY — 2026-05-17)
When changing CSS for any <select> / <details> / form control on a page that loads a forms-styling framework (@tailwindcss/forms, Bootstrap form-select, Bulma, etc.), the CSS MUST resolve which chevron/marker is visible — never let two systems paint the same affordance.
Two valid patterns for <select>:
.your-select {
appearance: auto;
background-image: none !important;
}
.your-select {
appearance: none !important;
-webkit-appearance: none !important;
background-image: none !important;
}
Forbidden state: appearance unset/auto AND background-image unset, with a forms-plugin loaded → double chevron.
Same rule for <details><summary>: either hide ::-webkit-details-marker and use an inline glyph, or use the native marker and skip the glyph — never both.
How to apply: when invoked in debug or review mode and the user mentions "double down arrow", "two chevrons", "stacked icons", "duplicate caret", "X is showing twice", or any UI page mixing Tailwind/Bootstrap forms with native <select>/<details>, load references/ui-duplicate-affordance.md and run its 5-step detection recipe. Add a regression test that locks the CSS rule AND enforces every control on the page carries a discipline class.
Why (2026-05-17, IBA-m69): ImproveBayArea /reports?city=san-francisco showed two stacked ▼ on the "Closed reports" filter because .report-select used appearance: auto (native chevron) without background-image: none (@tailwindcss/forms painted a second chevron on top). Fix took 1 CSS line + 1 regression test. Cataloged so the next instance — on any project — is caught in the audit pass.
Anti-Slop TypeScript — No Generic Type-Guard Boilerplate (MANDATORY — 2026-06-25)
When writing or reviewing TypeScript, never default to a generic loose type guard — reach for a specific type, discriminated union, or schema first. This is the runtime-guard sibling of the No-Suppression Rule: isRecord/isObject/as unknown as T/(x as any).field make code run on data of unknown shape without ever stating the shape, pushing type errors to a 2am production TypeError. It's the #1 AI "vibe-coding" tell. Full standard + alternatives + Zod patterns: ~/.claude/skills/shared/anti-slop-typescript.md.
Forbidden: function isRecord(o: unknown): o is Record<string, unknown>, isObject, copy-pasted structural guards across files, blanket as any / as unknown as T launder-casts, (obj as any).field reach-casts.
Required (priority order): (1) a named interface/type; (2) a discriminated union narrowed on a literal field; (3) a Zod/Valibot schema at every trust boundary with type X = z.infer<typeof Schema> (one source of truth); (4) library-inferred types (z.infer, Prisma/Drizzle $inferSelect, tRPC, Hono InferResponseType); (5) a targeted predicate checking the fields you actually use — last resort, justified inline.
How to apply: in feature, debug, or review mode on any .ts/.tsx, run ~/.claude/skills/carmack/tools/detect-ts-slop.sh [path|--diff <base>]. It flags generic guards, launder-casts, and reach-casts with file:line + a refactor hint. Treat every hit as a fix-list item (Fix-All-Issues rule), not a report — refactor to a specific type/schema; a guard that's genuinely the right tool stays but is justified inline. Typed code should compile (tsc --noEmit) with zero casts added to make it pass.
Why (2026-06-25): user flagged repetitive generic isRecord/loose-guard output as slop — code that compiles and runs but is never actually typed, the upstream cause of the undefined/null-render bug class. Stating the type (or a schema) IS the work; the generic guard is the avoidance of it.
New-Site Default = Hono Framework (MANDATORY — 2026-06-04)
Any time the user asks to build, create, scaffold, or "make" a new website or web app — OR to convert/remake an existing site — DEFAULT to the Hono framework (SSR + islands on Cloudflare Workers) by loading the /hono skill (~/.claude/skills/hono/SKILL.md). Do not reach for a React/Vue/Next SPA scaffold unless the user explicitly names a different stack. hono/jsx for server SSR, hono/jsx/dom for interactive islands, dual client/server Vite build, static assets via wrangler assets. The /hono references are verified against hono.dev — use them; don't invent Hono APIs from memory.
SPA→SSR Conversion = Audit Global App.tsx Mounts FIRST (MANDATORY — 2026-06-28)
Before converting ANY React-SPA route to SSR (hono/jsx, Astro, Next RSC), enumerate every component mounted globally in App.tsx/the SPA root — and re-provide each one on the SSR page. SSR does not mount your React tree, so each global component silently disappears from the converted route with NO error, NO console log, NO diff that flags it. The at-risk set: floating support/chat widget, cookie/consent banner (legal!), analytics beacon, exit-intent modal, toast host, providers, and any ?param deep-link handler (?support=open, ?ref=, UTM-driven UI).
Run before the first conversion and re-run after each route:
grep -nE "<[A-Z][A-Za-z]+ ?/?>" src/react-app/App.tsx | grep -viE "Route|Router|Routes|Suspense|ErrorBoundary|Navigate|HelmetProvider"
For each hit, the SSR page must provide it as a shared island (mount the existing React component — reuse, don't rewrite — into a placeholder via the SSR layout, on EVERY SSR page), an SSR equivalent, or a static fallback that itself still works. Watch the incremental trap: an affordance can keep "working" because a static link bounces to a route that's still SPA — then you SSR-convert that route too and the last mount point vanishes. Verify the thing acts (chat opens, banner shows, deep-link fires) in a real browser — not that the link/markup is merely present. Single-affordance: hide the static no-JS fallback once the island hydrates.
Why (2026-06-28, exampleapp): SSR-converting the 7 public pages — including / — dropped the global SupportChatWidget (App.tsx:167); public-layout.tsx had only a static <a href="/?support=open"> that relied on / being the SPA, so once / was SSR the live chat + the ?support=open email deep-link were dead on all 7 pages. Fix 7a25f67: a shared support-island.tsx mounting the existing widget on every SSR page. Full pattern: ~/.claude/skills/debug/references/react-patterns.md #24.
ALSO verify the rendered CASCADE, not just presence (the 🛑 hardest rule): after wiring islands, the bundled island/Tailwind CSS you <link> for the widgets often transitively imports the app's global index.css, whose element-selector rules (body{background:var(--color-bg);color:var(--color-text)}) load AFTER the SSR page's inline <style> and silently override the SSR design → invisible text, wrong background, on EVERY SSR page — with no error, clean diff, passing CSP/<h1> checks. After ANY SSR+island change you MUST drive the live browser on EVERY SSR route and assert getComputedStyle(document.body) bg/color equals the intended token (not a leaked fallback like rgb(240,240,240)) and that headings pass WCAG-AA against their ACTUAL computed bg — plus eyeball a screenshot. Fix: SSR layout body{background:…!important;color:…!important} (leaked rules carry no !important) or stop the island bundle emitting global body rules. Reference: 2026-06-28 — support-island.css leaked body{background:#f0f0f0} → white headings invisible site-wide, shipped twice undetected (checks verified "chat opens", not page background); fix cd0cdfe. Full pattern: ~/.claude/skills/debug/references/react-patterns.md #25; /ship gate 1.3c.
Site a11y + CSP Baseline — always add when building/touching a public site (MANDATORY — 2026-06-04)
When building a new site OR modifying any public-facing site, ALWAYS add/verify these three before declaring done — they are not optional polish:
