verify

A command that checks whether recent code works by examining the environment, types, style rules, and automated tests.

In plain words
What is it for?
Use it after coding or before review, with a full run for environment, type, lint, and test checks, or a quick run for only type and lint checks.
Why use it?
It catches common problems before code review without performing the separate review and security checks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 29 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 192 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

verify 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.

What it actually says

Verify Command

Use the Skill tool to invoke verification-loop explicitly, then run Phases 1-4 only:

  1. Environment check
  2. Type check
  3. Lint check
  4. Test suite

If the Skill tool is not available or the skill is not found, run the checks directly using the commands from each phase (see the verification-loop skill for exact commands).

Report results. Do NOT run code review (Phase 5) or security scan (Phase 6) — Phase 6 is for /quality-gate.

Arguments

$ARGUMENTS can be:

  • quick — Only phases 2-3 (types + lint, skip tests)
  • full — Phases 1-4 (default)
Changes

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.

verify is a command published in the GitHub repository Benkapner/claude-code-basecamp (16 stars, last pushed 12d ago), licensed MIT. It adds 29 tokens to every session and 192 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.
