Check is an agent skill from go-to-k/cdkd. Run local quality checks (typecheck, lint, build, tests). Quick check during development.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Linting and formatting. It works with TypeScript, Amazon Web Services and AWS CloudFormation. The repository describes itself as: Drop-in CDK CLI for existing CDK apps — up to 15x faster deploys via direct AWS SDK calls instead of CloudFormation. The licence is Apache-2.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 8a604fd. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitpnpmFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git and pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Check loads about 1.5k tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 570 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Walk these BEFORE the commands below and before committing. A green suite says the tests pass, not that the work is good, and none of these four is something a runner reports.
Say out loud what you found, then fix it before running the checks.
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 without it vp check
fails with an unnamed typescript(tsconfig-error): Invalid tsconfig — Cannot find type definition file for 'node', reading like a broken fixture
tsconfig.
vp check --fix (typecheck + lint + Prettier, auto-fix), then vp run check
— the exact command CI's check-build-test job runs. They are NOT equivalent:
vp check --fix has passed with 0 errors on a tree vp run check failed. Do
not substitute vp run lint:fix, which does not touch Prettier, so a
lint:fix-only run passes locally while CI fails Formatting issues found.
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, and vp test's Type Errors line covers only *.test-d.ts.
A wrong import type or stale mock shape in a test file is invisible without
this step.
vp run build.
Then regenerate the generated artifacts, unconditionally:
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, and a verify.sh edit with no
src change stales cli-flag-coverage.
vp test run — the whole unit suite. Prefer this over vp run test: nothing
sits between the caller and the verdict.
Read the summary's NUMBERS, not its colour, and read the Errors line, which
is NOT Type Errors. Test Files N passed (N) is self-consistent over a
suite that LOST files before they ran, so it cannot report its own shortfall:
a loaded host produces [vitest-pool]: Failed to start forks worker beside an
otherwise green summary. vp test run --maxWorkers=4 is the remedy for the
whole [vitest-pool] / [vitest-pool-runner] family.
Also check WHICH PROJECT the summary belongs to — the summary line cannot tell you, and a run launched from this worktree has been observed printing a sibling project's suite. Assert the root in the same command that produces the verdict, and read the suite's own rc, not the trailing grep's:
# Subshell so the `exit`s are safe to paste into an interactive shell.
(
log=$(mktemp) # NOT a fixed path: concurrent lanes share /tmp.
echo "log: $log" # print BEFORE the exits, or a failing run is unrecoverable.
vp test run > "$log" 2>&1; rc=$?
runs=$(grep -c 'RUN v' "$log")
[ "$runs" = 1 ] || { echo "expected 1 RUN header, found $runs -- attests to nothing; log: $log"; exit 1; }
run_root=$(grep -m1 -oE "RUN v[0-9.]+ .*" "$log" | sed 's/^RUN v[0-9.]* //')
[ "$run_root" = "$(pwd -P)" ] || { echo "WRONG PROJECT ($run_root) -- attests to nothing; log: $log"; exit 1; }
# The alternatives are chosen against the COLOURED bytes: vitest pads the
# label inside the dim escape, so ` Tests ` survives colouring and
# `Tests +[0-9]` does not. Do not tighten either one.
grep -E "Test Files| Tests |Type Errors|Errors.*[0-9]+ error" "$log"
if [ "$rc" != 0 ]; then
echo "SUITE FAILED rc=$rc; log: $log"
grep -qE '\[vitest-pool(-runner)?\]: ' "$log" \
&& echo " the pool lost workers before their files ran, so the passing counts above cover only what survived -- re-run with --maxWorkers=4"
exit 1
fi
# A run that exited 0 can still have COLLECTED fewer files than the tree
# holds (a stray filter, a narrowed include). Unanchored `(N)`: the
# coloured summary ends in an escape, not in `)`.
collected=$(grep 'Test Files' "$log" | grep -oE '\([0-9]+\)' | tail -1 | tr -d '()')
# `:(glob)` on every pathspec: git's bare `**` demands an intervening `/`
# while vitest's does not.
ondisk=$(git ls-files ':(glob)tests/**/*.test.ts' ':(glob)src/**/*.test.ts' \
':(glob)tests/**/*.test-d.ts' ':(glob)src/**/*.test-d.ts' | wc -l | tr -d ' ')
# `-ge`, not `=`: an untracked new test file is collected but not listed.
[ "${collected:-0}" -ge "$ondisk" ] || { echo "COLLECTED ${collected:-none} of $ondisk tracked test files over a run that exited 0 -- attests to nothing; log: $log"; exit 1; }
)The wrong-project symptom is contention-dependent, not sticky — re-running usually lands right.
Report as a table:
| Check | Result |
|---|---|
typecheck + lint + format (vp check --fix) | pass/fail |
test-project typecheck (vp run typecheck:test) | pass/fail |
| build | pass/fail |
tests (N files, M tests) (vp test run) | pass/fail |
If all pass, confirm "All checks passed." If any fail, show the error output and STOP — fix the failures and re-run before committing.
These checks attest to the working-tree state at the time of the run, so re-run after any further edit.

Check fits situations like: tasks that involve Linting and formatting.
Run `npx skills add go-to-k/cdkd --skill check -a claude-code`. Or copy the skill folder (.claude/skills/check in go-to-k/cdkd) into .claude/skills/check in your project. Claude Code loads it when a task matches its description.
Run `npx skills add go-to-k/cdkd --skill check -a codex`. Or copy the skill folder (.claude/skills/check in go-to-k/cdkd) into .agents/skills/check in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add go-to-k/cdkd --skill check -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/check, .gemini/skills/check, .github/skills/check and .opencode/skills/check in your project.
Going by SKILL.md and its folder, Check needs the command-line tools its instructions call (git and pnpm).
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Check is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
