What it does

Piv Validate is an agent skill from coleam00/skills. Runs this project's full validation suite — tests, type checks, and linting across every part of the stack — then reports overall health. Use before committing, before opening a PR, or after finishing a chunk of work to confirm zero regressions.

Its SKILL.md is about 780 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. The repository describes itself as: The agent skills I actually use to build software with coding agents. The PIV loop, planning, worktrees, and the meta-skills for building your own AI Layer. The licence is MIT.

When your agent uses it

  • Tasks that involve Linting and formatting

Example prompts

  • “/piv-validate”

Requirements

  • Docker

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Tests
  2. Type check
  3. Lint / format check
  4. Repeat per surface
  5. Optional — live smoke test
  6. Summary report

What it can do on your machine

Read from SKILL.md and the folder at commit 847be08. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Piv Validate loads about 781 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 383 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~781

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.

Safety

Auto-check passed

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.

Validate

Run every check this project has and report a single PASS/FAIL verdict.

⚠️ Make this yours first

This skill is a template. The command list below is a placeholder — replace it with the commands your project actually uses. That is the entire point of a custom checker: it is the one skill that cannot be generic, because it wraps your stack's CLIs.

Find your real commands in package.json scripts, pyproject.toml, Makefile, justfile, docker-compose.yml, your CI workflow, or the README — then delete these and paste yours in.

Two things to get right, because they are the usual reason a checker silently lies:

  1. Working directory. Many tools only discover their config from the current directory. If your config lives in backend/pyproject.toml, the command is cd backend && uv run pytest, not uv run pytest from the repo root.
  2. Cross-platform. Avoid POSIX-only idioms if anyone on the team is on Windows — lsof, python3, and background-then-kill are the common offenders.

Run the checks in order. Keep going after a failure so the report covers everything, and capture the output of any command that fails.

1. Tests

bash
# REPLACE: your test command, run from the right directory
<your test command>

Expected: all tests pass.

2. Type check

bash
# REPLACE: e.g. mypy, tsc --noEmit, go vet
<your type-check command>

Expected: no type errors.

3. Lint / format check

bash
# REPLACE: e.g. ruff check, biome check, eslint
<your lint command>

Expected: clean.

4. Repeat per surface

A full-stack project has more than one of each. Add a section per surface — backend tests, backend types, backend lint, frontend tests, frontend types, frontend lint — so a single command covers the whole repo.

Show full SKILL.md (145 more words)Show less

5. Optional — live smoke test

Only when the change touches routing, middleware, or startup; skip it when your test suite already exercises the app in-process.

bash
# REPLACE: start your app, hit one endpoint, confirm the status code, stop it
<your run command>

Prefer starting the server in a second shell over backgrounding and killing it from inside this skill — the background-and-kill idiom is not portable.

6. Summary report

Report each check with a ✅ or ❌, then an overall verdict:

  • One line per check
  • Overall: PASS or FAIL

For every ❌, include the failing command and the relevant output. Do not fix anything here — this skill reports; fixing is a separate step.

Notes

  • Keep this skill fast. It runs before every commit; if a step gets slow, that is a signal to fix the slow step, not to drop it from the checker.
  • A checker that cannot fail is worthless. Once your commands are wired in, break something on purpose and confirm this skill reports ❌.
