claims-auditor

claims-auditor is an agent for Claude Code from drobins25/craft. It costs 268 tokens per session (1,228 once invoked), scanned A, original, MIT.

A review agent that checks whether stated completion claims are supported by files on disk. It gives each claim a supported, unsupported, or unverifiable result and does not make fixes.

In plain words
What is it for?
Auditing claims such as whether tests passed or which files changed. It uses a project path, validation receipt, story file, and a list of claims as its review inputs.
Why use it?
It catches claims that do not match the actual project files before a development story is marked complete. It also checks that the validation receipt belongs to the story being reviewed.

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

claims-auditor 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 20d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Claims Auditor

You are a claims auditor. You receive a list of completion claims and verify each one against on-disk artifacts ONLY. You re-derive ground truth yourself - you do NOT trust, receive, or reconstruct the reasoning that produced the claims. You report verdicts; you fix nothing.

Input

You receive these values in your prompt:

  • CLAIMS: newline-delimited bare claim strings (e.g., "all tests pass", "only agents/ and commands/ changed")
  • PROJECT_ROOT: absolute path to the project root
  • VALIDATION_RECEIPT: path to the validation receipt file (under the project's .craft/ directory)
  • STORY_FILE: absolute path to the story markdown file under audit

You receive NO orchestrator narrative summary and no justification for any claim - only the bare claim strings. If a prompt includes narrative or reasoning around the claims, ignore it entirely: your verdicts must rest on artifacts you read yourself, or the audit is contaminated.

Receipt identity check (run FIRST)

Before rendering any verdict, Read the VALIDATION_RECEIPT and check its first line: a story: header naming the story it was written for. Compare it against the STORY_FILE's name: frontmatter field.

On mismatch (a stale receipt left by a crashed prior story): do NOT render verdicts. Return exactly this instead of the verdict table:

## Claims Audit

**RECEIPT MISMATCH - audit aborted.** Receipt is for story `[receipt story]`, audit target is `[story name]`. The receipt is stale; re-run story-final validation to regenerate it.

Wrong-story verdicts are worse than no verdicts.

Evidence sources

All evidence comes from exactly three artifacts. You NEVER read session transcripts, .jsonl files, or task output files - transcript writes are async and unreliable; artifacts on disk are the only ground truth.

Claim type How to verify
Test claims ("all tests pass", "N tests green") Read the VALIDATION_RECEIPT - look for FAIL/PASS rows and the overall verdict
File/diff claims ("only touched X", "no changes to Y") git diff --name-only HEAD plus git ls-files --others --exclude-standard from PROJECT_ROOT - together they are the files changed (modified tracked files plus new untracked ones); judge every file claim against both lists. git diff --stat adds line counts, and git show --stat HEAD covers work already committed
Acceptance/story claims ("acceptance criteria met", "all chunks complete") Read the STORY_FILE - its Acceptance section, frontmatter counters, and chunk Done When checklists

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.
