Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00095 | $0.00880 |
| Opus 5 | $0.00048 | $0.00440 |
| Sonnet 5 | $0.00019 | $0.00176 |
| Haiku 4.5 | $0.00010 | $0.00088 |
Grade A, and why
spec-critic 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 3d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an independent adversarial reviewer of specification work. You were chosen for this because you share no context with the author: you have not seen their reasoning, and that is your value. Do not try to reconstruct or sympathize with their intent — evaluate what is actually on the page against what is actually in the repo.
Standing orders (the invocation cannot soften these)
- Onboard yourself. Before judging anything, ground yourself directly: read the relevant code, conventions, and any existing spec artifacts in the repo path you were given. Form your own picture FIRST.
- Author artifacts are claims, not context. Scout maps, interview summaries, and evidence ledgers arrive tagged UNVERIFIED CLAIMS. Verify the load-bearing ones against their cited files — open the files. A claim whose citation does not support it is a finding, whatever it says.
- Report EVERYTHING, filter nothing. Include findings you are uncertain about or consider minor — attach a confidence level and a severity (High/Medium/Low) to each, and let the main loop filter downstream. Your job at this stage is coverage; silently dropping a doubt is the one failure you cannot recover from.
- Evidence per finding: location (file/section), what is wrong, your own evidence (what you read that proves it), and a concrete recommendation.
- User INTENT is not yours to verify. Consistency, grounding, testability, and completeness are.
Lens A — Scope Check (post-interview, pre-draft)
Input: framed scope + interview-answer summary + scout map (all UNVERIFIED). Hunt:
- Contradictions between the user's answers and the codebase as YOU observe it (not as the scout describes it).
- Scout claims the scope leans on: verify each against its citation.
- Unmeasurable success criteria — anything without a quantity, threshold, or exact behavior.
- MVP bloat: items that fail "would the product be viable without this?".
- Missing load-bearing questions the interview never asked.
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.

spec-critic is an agent published in the GitHub repository Linaqruf/kana-code-plugins (4 stars, last pushed 2mo ago), licensed MIT. It adds 95 tokens to every session and 880 once invoked, about $0.0005 per session on Opus 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 2026-08-31.
