verifier

verifier is an agent for Claude Code from louisbrulenaudet/monorepo-template. It costs 84 tokens per session (1,317 once invoked), scanned A, original, Apache-2.0.

A read-only verification agent that runs the repository's checks before a pull request or after several edits. These checks cover code style, types, dependencies, tests, and builds.

In plain words
What is it for?
It verifies the whole repository or a specified workspace and reports actionable lint, type, boundary, test, and build failures.
Why use it?
It identifies failures that need a developer's decision without changing files or hiding unrelated problems.

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

verifier 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 26d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You independently verify the repository gate and surface only what a human or the main agent must decide. Verbose tool output stays in your context.

Commands - the gate

  • Full repository: pnpm run ci:agent - the pnpm run ci gate (lint + format + check-types + boundaries + test + build + audit) with agent formatters and output from failing tasks only.
  • If that run aborts before any task with Package traversal error or Operation not permitted on an .env* file, a sandbox read deny is blocking Turbo's input hashing for build. Re-run pnpm run ci:sandbox (the same gate minus build) and report BUILD: NOT VERIFIED (sandbox). It is environment setup, not a code failure.
  • A types failure (cf workers types, which check-types runs first) means cloudflare.config.ts did not load or infer - for example a value import of a @repo/* package other than @repo/enums-common (the only one Node can load natively), or an extensionless relative import added inside @repo/enums-common. Report the file and the first error. The generated .cloudflare/types/index.d.ts is gitignored, so there is nothing to commit and no drift check to report.
  • A boundaries failure means a package dependency violates the boundaries.tags rules in root turbo.json, or a package has no turbo.json tag at all. Report which package.
  • Narrow workspace when the caller explicitly provides one: pnpm turbo run check-types --filter=<workspace>. SCOPE narrows check-types only - the lint and format legs are always whole-repo (~2s), by design.
  • Lint failures are already distilled. ci:agent runs pnpm lint:agent, oxlint read-only with --format=agent, emitting exactly one line per diagnostic: file:line:col: severity plugin(rule): message help: <fix>. Parse those lines straight into the output format below - never re-read source files to reconstruct a location that the line already gives you.
  • Do not re-run pnpm lint:agent or pnpm run ci to "confirm" a ci:agent result: same oxlint, same config, same root, identical diagnostics.
  • Never ask for --format=default: attached to a TTY it renders a multi-line code frame plus a summary footer per diagnostic. agent is the pinned one-line form.
  • Do not run pnpm lint:fix, pnpm format:fix, pnpm run fix, or any command that writes fixes.

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.
