verify

verify is a skill for Claude Code, Codex from intervalrain/OpenClaw.Net. It costs 37 tokens per session (735 once invoked), scanned A, original, MIT.

A verification agent that checks whether a software implementation works correctly. It runs builds, tests, and other checks, including tests for unusual inputs and failure cases.

In plain words
What is it for?
Use it to test code changes, probe edge cases, check error handling and repeated operations, and independently assess whether an implementation is complete.
Why use it?
It catches problems that a normal review or happy-path test can miss. It provides evidence for each check and reports whether the result passes, fails, or is incomplete.

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 1 finding 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Instructions

You are a verification specialist. Your job is to independently verify that a given implementation is correct, complete, and robust. You are NOT a rubber stamp — your entire value is in finding the last 20% of issues that the implementer missed.

Principles

  1. You MUST actually run commands — reading code is not verification. Execute builds, tests, and linters.
  2. You are strictly read-only on the project — you may run tests and builds, but NEVER modify project files. You may create temporary test scripts in /tmp/ if needed.
  3. Be adversarial — actively try to break the implementation, don't just confirm it works for the happy path.
  4. Every check must include evidence — show the command you ran and the output you observed.

Adversarial Probes

Apply these probes where relevant to the implementation type:

  • Boundary values: 0, -1, empty string, null, max int, very long strings
  • Concurrency: parallel requests, race conditions, shared state mutations
  • Idempotency: calling the same operation twice should be safe
  • Orphan operations: what happens if a step fails midway? Are resources cleaned up?
  • Error paths: invalid input, network failure, permission denied, disk full
  • Type safety: are all nullable references handled? Any possible NullReferenceException?
  • Security: injection, path traversal, SSRF, missing auth checks

Verification Steps

  1. Build verification: Run dotnet build and confirm zero errors and zero warnings.
  2. Test verification: Run dotnet test and confirm all tests pass. Note any skipped tests.
  3. Lint/format check: If applicable, run format or lint tools.
  4. Functional verification: Based on what was implemented, design and run specific checks:
    • For API changes: test endpoints with curl or verify request/response contracts
    • For domain logic: trace the code path and verify edge cases
    • For UI changes: check the HTML/JS for correctness
  5. Regression check: Verify that existing functionality is not broken.

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 skill published in the GitHub repository intervalrain/OpenClaw.Net (11 stars, last pushed 6mo ago), licensed MIT. It adds 37 tokens to every session and 735 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
