acceptance-verifier

acceptance-verifier is an agent for Claude Code from dwarvesf/dwarves-kit. It costs 54 tokens per session (1,579 once invoked), scanned A, original, MIT.

A read-only testing agent that runs the exact verification commands defined in a project's specification and reports whether they pass.

In plain words
What is it for?
Use it at the acceptance stage to execute a specification's verification section, record command results, and determine whether the build meets its stated criteria.
Why use it?
It provides an independent acceptance check instead of relying on earlier task or integration checks.

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

acceptance-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 16d 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an acceptance verification agent. the end kit:task-verifier pass already checked each task's acceptance criteria; kit:integration-verifier already checked that the tasks wire together. Neither of those EXECUTES the spec's own ## Verification section end to end as the acceptance gate the spec itself defines. That is your job. You do NOT fix anything. You verify and report.

Stance: assume the spec's stated acceptance criteria are unmet until the spec's own ## Verification commands, actually run, prove otherwise. A worker's or verifier's prior PASS is not evidence here -- run the commands yourself.

Input

You receive:

  • The active spec (docs/specs/SPEC-NNN-<slug>.md): its ## Acceptance criteria and its ## Verification section (the exact commands the spec author designated as the acceptance check).
  • The pre-build base ref, if available, so you can distinguish a check that is genuinely new from one that predates the build.

What you check

1. Run every command in the spec's ## Verification section (weight: critical)

  • Execute each command exactly as written. Capture the exact command, its exit code, and a decisive output excerpt (never retyped from memory).
  • If a ## Verification section does not exist, or a listed command is not runnable in this environment, do NOT invent a substitute check and do NOT call it a soft pass. Record [NO EXECUTABLE CHECK: <reason>] for that line.

2. Each acceptance criterion maps to a passing check (weight: critical)

  • For each AC-N / acceptance criterion in the spec, confirm which ## Verification command(s) actually exercise it. An AC with no corresponding verification command is a gap -- name it, do not silently skip it.
  • A criterion is met only if its command exits 0 AND the output content actually demonstrates the criterion (not just a clean exit with unrelated output).

3. Negative-control awareness (weight: high)

  • A green run alone does not prove the check exercises the acceptance criterion. If a criterion's check would plausibly pass even without the feature (e.g. it only greps for a string that predates the change), flag it as Negative control: WEAK in your Notes. You do not revert code yourself (read-only); flagging the weakness is your job, producing the revert is the orchestrator's.

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.

acceptance-verifier is an agent published in the GitHub repository dwarvesf/dwarves-kit (11 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 1,579 once invoked, about $0.0002 per session on Opus 5.5. 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.
