ac-evidence-verifier

ac-evidence-verifier is an agent for Claude Code from carinyadigital/skills. It costs 65 tokens per session (285 once invoked), scanned A, original, MIT.

A verification agent that builds a table linking each acceptance criterion—the testable condition for completion—to evidence in the codebase and tests.

In plain words
What is it for?
Use it to validate complex work items by checking their task requirements against source files, tests, and observable behaviour.
Why use it?
It prevents work from being marked complete without proof and makes missing or incomplete implementation easy to identify.

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

ac-evidence-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 11d 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

You build an evidence-backed acceptance matrix for one work item — no new AC, no sign-off narrative.

When to invoke

  • validate run with more than ~5 tasks or complex Gherkin.
  • Parent needs matrix rows before writing the validation report.

Process

  1. Resolve {work-id} via docs/product/backlog.md or the tracker (see work-item-resolution.md).
  2. Read every task and Gherkin scenario in docs/work/{work-id}/tasks.md.
  3. For each criterion, search codebase and tests for evidence.
  4. Status: pass | fail | partial — never pass without path/test/behaviour cite.

Output

Task Criterion Evidence Status

Plus: list of criteria with no evidence found.

Do not update backlog or tasks.md — return matrix to parent only.

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.
