cross-model-review — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited cross-model-review (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.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Source: points/named-failure-modes.md, points/banned-jargon.md, points/pre-send-checklist.md, points/cold-email-rules.md, points/ai-writing-rules.md. Read those first.
The model that drafted the email rationalizes its own choices. It picked the personalization, so the angle feels genuine. It used the word, so the word doesn't read as jargon. It made the claim, so the claim feels supported.
A second model — different weights, no investment in the draft — sees what the first model rationalized away. That's the whole point. If this skill runs on the same model that drafted, it adds nothing.
You are NOT here to make the email better. You are here to decide whether it ships.
Two verdicts only:
PASS — ship itFAIL — block, with the specific named failure modes listedBorderline → fail. Cost of a block is one rewrite cycle. Cost of a templated email is the recipient's read of the sender forever.
The orchestrator (coach.html, cold-email-coach, or the user) routes to a different model than the drafter. This skill assumes routing already happened.
If the user explicitly says you are the same model that drafted, output CANNOT REVIEW — same model as drafter and stop.
recipient-research)about-me.mdIf any are missing, output CANNOT REVIEW — missing [input] and stop. Do not guess.
When you fail an email, name the mode in plain English so the sender knows what to rewrite, not just where they scored low. See points/named-failure-modes.md for the full catalog. Summary:
Any one named mode = FAIL.
Always run this, even on PASS. Predict the recipient's most likely one-sentence reflex reply. The four most common:
Pick the most likely one. Ask: is the sender ready for that follow-up? If not, that's a different kind of work to flag — the gate may still PASS but the email isn't shippable until the sender prepares.
This is a forcing function, not a gate. It's about the next move, not the current draft.
