validate-component

A project check runner for a newly written component, a reusable interface element such as a button or form, in a TypeScript and Storybook codebase.

In plain words
What is it for?
Use it to run the project's four checks in order and report the first failure with its output details.
Why use it?
It finds linting, type, type-coverage, or Storybook build failures without changing the code.

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.

Security

Grade A, and why

validate-component 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 yesterday.

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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill: validate-component

Purpose

Confirm the scaffolded component compiles, lints, types, and builds. Surfaces failures to the orchestrator so the run can be marked degraded or rolled back.

When to invoke

  • Step 8 of /component-create, after echo-reporter confirmed parity.

Inputs

  • The list of files written this run (from the orchestrator's run log).
  • No mutation of the codebase.

Workflow

Run the four checks in this fixed order; stop on the first failure and surface it:

# Command Failure means
1 pnpm webkit:lint ESLint reports an error or warning that crosses the project threshold.
2 pnpm webkit:type-check vue-tsc reports a TypeScript error in the component, its sub-components, or the consuming exports.
3 pnpm webkit:type-coverage Type coverage below the threshold (project default: 95%).
4 pnpm storybook:build The new .stories.js breaks the Storybook build.

For each command, capture the exit code and the last 40 lines of stdout/stderr. Emit a table:

| Check | Result | Detail |
|---|---|---|
| `pnpm webkit:lint` | ✅ pass | 0 warnings |
| `pnpm webkit:type-check` | ✅ pass | — |
| `pnpm webkit:type-coverage` | ✅ pass | 97.2% (threshold 95%) |
| `pnpm storybook:build` | ✅ pass | build output OK |

If any row is ❌, include the last 40 lines of the tool's output below the table and stop.

Outputs

  • The Markdown table above + (on failure) the tail of the failing command's output.

Rules

  • Do not auto-fix lint failures. Surface them and stop — the user (or a follow-up sub-agent) decides whether to fix.
  • Do not run pnpm install. If a dep is missing, surface that as the failure reason.
  • Do not run git. Validation never touches the working tree.

Fallbacks

  • A script is missing from package.json → emit BLOCKED: script <name> not found in root package.json.
  • A command hangs > 5 min → emit BLOCKED: <command> timed out and exit.

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.
