review-spec — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited review-spec (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
review-spec validates whether a specification is strong enough to become the source of truth for planning, TDD, implementation, and verification. It is a read-only quality gate. It does not write code and it does not approve execution by itself.
Use this workflow to prevent weak specs from becoming precise-looking plans with hidden ambiguity.
No implementation plan from an unreviewed or materially ambiguous spec.If the spec cannot be tested, reviewed against code, or handed to another agent without guessing, return CHANGES REQUIRED.

Classify the spec as one or more:
Use the classification to decide which checks matter most. For example, an API spec must define request/response contracts and error behavior; a UI spec must define states, accessibility requirements, and responsive behavior.
Evaluate the spec using these criteria:
| Area | Required standard |
|---|---|
| Objective | One clear outcome, user/system value, and non-goals |
| Scope | Explicit in-scope and out-of-scope boundaries |
| Behavior | Observable acceptance criteria, including failure states |
| Contracts | API, data, events, files, or UI state contracts are concrete |
| Architecture | Fits existing patterns or names required ADR/escalation |
| Dependencies | Upstream/downstream dependencies and ordering are known |
| Verification | Commands, tests, build, lint, manual, or visual checks are named |
| Rollback | Risk and rollback/disable path are stated for risky changes |
| Handoff | Another agent can plan from it without inventing requirements |
Flag these as blocking unless explicitly out of scope:

flows.
If drift is found, do not resolve it inside this workflow. Recommend spec-evolution and name the exact mismatch.
Use this exact verdict scale:
APPROVED: Ready for planning-and-task-breakdown or test-driven-development.APPROVED WITH NOTES: Minor non-blocking gaps remain; execution can proceedif the notes are carried into the plan.
CHANGES REQUIRED: The spec is not ready; revise before planning or code.ROUTE TO SPEC-EVOLUTION: The spec/code reality mismatch must be resolvedbefore planning, implementation, or review can continue.
## Spec Review: [Spec Name]
**Source:** [file/path or request summary]
**Spec Type:** [product / technical / API / UI / verification / release]
**Readiness Score:** [X/9]
### Blocking Issues
- [Issue with exact section/file reference, or "None"]
### Non-Blocking Notes
- [Note, or "None"]
### Missing Acceptance Criteria
- [Specific missing criterion, or "None"]
### Verification Fit
[Whether the spec can be verified, with named commands/checks if present.]
### Drift Check
[No drift found / suspected drift / confirmed drift with exact mismatch.]
### Verdict
`APPROVED` | `APPROVED WITH NOTES` | `CHANGES REQUIRED` | `ROUTE TO SPEC-EVOLUTION`| Thought | Required correction |
|---|---|
| "The spec is good enough; planning will clarify it." | Planning should decompose decisions, not invent requirements. |
| "The code will reveal the details." | Details discovered in code must be reflected through spec-evolution. |
| "This is only a small spec." | Small specs still need observable acceptance criteria. |
| "The user knows what they mean." | The agent executing the plan needs explicit, reviewable language. |
| "I can approve with obvious assumptions." | List assumptions as blockers or notes. Do not hide them. |
