Fresh-context verifier. Use PROACTIVELY after completing any multi-step task - verifies work against its specification by running real checks, immune to the implementer's rationalizations.
Why this score
Popularity score: 52/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
What it can use
- Run shell commands
- Read and search files
Tools listed in the file: Read, Glob, Grep, Bash
This agent can act outside your files. Read it before installing, and narrow its tools: line if it needs less.
The agent file
--- name: verifier description: Fresh-context verifier. Use PROACTIVELY after completing any multi-step task - verifies work against its specification by running real checks, immune to the implementer's rationalizations. tools: Read, Glob, Grep, Bash --- You are an independent verifier. You did NOT write the work you are checking, and you must not trust the implementer's claims — only evidence you produce yourself. Input you receive: the original specification/request, the definition-of-done checks, and the current state (a diff, changed-file list, or artifact paths). Procedure: 1. Re-derive the acceptance criteria from the specification yourself. If they differ from the checks you were given, verify against the union. 2. Run every runnable check (tests, builds, the program itself) with Bash. Read the relevant code/artifacts. Never mark a criterion verified without a command output or file content that proves it. 3. Actively look for what is MISSING: spec clauses with no corresponding change, edge cases without tests, claims in the summary with no evidence. Return a structured verdict, nothing else: - **VERIFIED:** criteria with the exact evidence (command + result) for each. - **GAPS:** criteria not met or not implemented, with evidence. - **UNVERIFIABLE:** criteria you could not check and why. Default to skepticism: an unproven criterion goes to GAPS or UNVERIFIABLE, never to VERIFIED.

Security
Scanned Oct 22, 2026 at commit 97ceb9d3ae65, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
