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 5.1 | $0.00097 | $0.01402 |
| Opus 5 | $0.00048 | $0.00701 |
| Sonnet 5 | $0.00019 | $0.00280 |
| Haiku 4.5 | $0.00010 | $0.00140 |
Grade A, and why
cy-spec-peer-review 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.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spec Peer Review
Codex authors AGH TechSpecs with gpt-5.4 at reasoning_effort=xhigh; Claude Opus pressure-tests them. This skill runs that pressure-test only when the user explicitly asks for a review round after approving the current draft. It does not auto-run, auto-incorporate findings, or auto-loop additional rounds.
User Decisions
When this skill instructs the agent to ask whether to incorporate findings or run another round, it MUST use the runtime's dedicated interactive question tool — the tool or function that presents a question to the user and pauses execution until the user responds.
If the runtime does not provide such a tool, present the question as the complete assistant message and stop generating. Do not answer the question on the user's behalf.
Required Inputs
- techspec-path (optional): explicit path to the
_techspec.mdunder review. When omitted, resolve to the most recently modified.compozy/tasks/<slug>/_techspec.mdwhose sibling_meta.mdshowsPending: > 0or no_meta.mdexists yet.
Procedures
Step 1: Validate Input and Context
- Resolve
techspec-path. If omitted, list candidate paths and pick the freshest. - Confirm the user has already approved the current draft or explicitly asked to review the saved spec as-is.
- Read the spec and confirm it is a final-shape TechSpec (has
Architectural Boundaries,Implementation Steps,Test Strategysections) — not a draft. - Read
references/quality-markers.mdand verify the spec carries the six markers (boundary statement, listed boundaries, Go interface signatures, data-model field rationale, side-table-vs-JSON decisions, lease/safety invariants enumerated). If any marker is missing, abort and report the missing markers — Opus review is wasted on incomplete specs. - Resolve the slug from the path; ensure
.compozy/tasks/<slug>/exists and is writable. - Determine the next review round number by listing existing
qa/peer-review-result-round*.jsonfiles. Start atround1when none exist.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cy-spec-peer-review is a skill published in the GitHub repository compozy/skeeper (85 stars, last pushed 3mo ago), licensed MIT. It adds 97 tokens to every session and 1,402 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 2026-08-30.
