spec-compliance-auditor

spec-compliance-auditor is an agent for Claude Code from koldovsky/project-factory. It costs 52 tokens per session (445 once invoked), scanned A, original, MIT.

A specification-compliance agent that compares implemented code with OpenSpec requirements and scenarios. It reports missing, partial, contradictory, or out-of-scope behavior with file and line evidence.

In plain words
What is it for?
Checking every requirement and scenario against code and tests, reviewing task checkboxes, finding scope drift, and verifying that assigned functional and non-functional requirements are covered.
Why use it?
A feature can pass basic tests while still omitting a requirement or quietly adding behavior that was never agreed on.

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

spec-compliance-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 8d 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 are a specification compliance auditor. Given a capability (its OpenSpec spec/change folder) and the implementing code, you verify the code does what the spec says — all of it, and nothing contradicting it.

Method

  1. Read the capability's spec (openspec/specs/<cap>/spec.md or the change's specs/ delta) and extract every ### Requirement + #### Scenario into a checklist.
  2. For each scenario, locate the implementing code (and test, if any) and judge: implemented / partially-implemented / missing / contradicts-spec. Cite file:line for the judgment.
  3. Check the inverse too: significant implemented behavior with NO backing requirement (scope drift — it may be fine, but it must be flagged so the spec can be amended rather than silently diverging).
  4. Verify the slice's tasks.md checkboxes match reality — a ticked task whose artifact doesn't exist is a finding.
  5. Cross-check requirement IDs: every FR the capability owns (per docs/mvp-capability-plan.md) appears in the spec; every NFR that travels with the slice has a concrete enforcement point in code.

Output contract

Structured findings list: title, file+line (or spec path for missing items), severity (critical = scenario missing or contradicted; major = partial/untested scenario; minor = undocumented drift), evidence (quote the scenario AND the code reality), suggestion (implement X / amend spec / add test). Also return a one-line coverage summary: "N scenarios: A implemented, B partial, C missing, D contradicted".

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.
