A local project check that runs type checking, code-style checks, formatting, builds, and tests.

Use it during development to verify that the current code works and to apply automatic formatting or fixes where supported.

It catches problems before code is sent to continuous integration—the automated checks run by a project after changes are submitted.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.01670
Opus 5	$0.00010	$0.00835
Sonnet 5	$0.00004	$0.00334
Haiku 4.5	$0.00002	$0.00167

Security

Grade A, and why

check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Local Quality Check

Run all local quality checks. Use during development to verify the current state quickly.

Steps

Run these sequentially and report results:

Worktree pre-flight: [ -d node_modules ] || pnpm install --frozen-lockfile. git worktree add does NOT copy node_modules, and in a fresh worktree vp check fails with an UNNAMED typescript(tsconfig-error): Invalid tsconfig — Cannot find type definition file for 'node', which reads like a broken fixture tsconfig. (/verify-pr step 0 has the same pre-flight; this copy exists because /check is usually the FIRST skill run in a fresh worktree.)
vp check --fix — typecheck + lint + Prettier, with auto-fix. Then vp run check — the EXACT command CI's check-build-test job runs. The two are NOT equivalent: vp check --fix has passed 0-errors while vp run check failed with a TS7053 on the same tree (PR #1372). Use this, not vp run lint:fix — lint:fix does not touch Prettier, so a lint:fix-only run passes locally while CI fails Formatting issues found (PR #363). Run both; CI parity comes from the second.
vp run typecheck:test — type-checks tsconfig.test.json (tests/**). vp check only type-checks tsconfig.json (src + types), which excludes **/*.test.ts — a wrong import type or stale mock shape in a test file passes vp check AND vp test (whose "Type Errors" line covers only *.test-d.ts). This step matches how CI fails them (issue #1133).
vp run build

Before step 4, regenerate the generated artifacts — UNCONDITIONALLY, offline, seconds: vp run gen:all-matrices && vp run audit:coverage:check && vp run format. The suite carries a byte-for-byte guard per generated matrix, and the trigger set is wider than any condition you would write — renaming a PRIVATE provider method stales handled-property-wiring.json (issue #1417's class); a verify.sh edit with no src change stales cli-flag-coverage (measured 2026-09-03: one private helper, two red cases, green after regeneration).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

check is a skill published in the GitHub repository go-to-k/cdkd (135 stars, last pushed today), licensed Apache-2.0. It adds 21 tokens to every session and 1,670 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
