sw-update-afebf6 — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited sw-update-afebf6 (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 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.
Pull upstream changes into an installed specwright's scaffolded content without clobbering local edits. The deterministic work (fetch, classify, auto-apply the safe cases) is the engine's; you only merge the files that genuinely conflict.
Announce at start: "Reconciling specwright against upstream..."
Only file-backed scaffold content, each compared by sha256 against a tracked baseline (the update manifest, kept under the skill at .agents/skills/sw/.update-manifest.json):
| Local path | Upstream source (in the clone) |
|---|---|
.agents/skills/sw-<name>/SKILL.md (brainstorming, writing-plans, new-pr, code-review, update) | <clone>/skills/sw/scaffold/skills/sw-<name>/SKILL.md |
the ### Spec flow block of AGENTS.md | the ### Spec flow block of <clone>/skills/sw/references/agents-md-template.md |
Never touched: .specwright/conventions/*, .specwright/specs/*, and the per-repo intro and non-spec-flow sections of AGENTS.md. This is living content — it has no single upstream file to hash.
bash .agents/skills/sw/scripts/sw-update.sh --runIt fetches the current upstream specwright (git clone --depth 1 — needs network), classifies every managed path, auto-applies the safe updates, and prints a report. No network → it stops with a clear message; re-run when online.
Read the report. The first line is the clone location:
clone /tmp/tmp.XXXXXXthen one line per managed path: current / updated / local-only / conflict + a tab + the path.
### Spec flow block was replaced; the per-repo intro is intact.)For every conflict line, keep the clone path from the report's first line and:
<clone>/…).AGENTS.md#spec-flow conflict, merge only the block between ### Spec flow and the next ## header.bash .agents/skills/sw/scripts/sw-update.sh --record <local-path> <clone>You are the only non-deterministic actor, and only on conflicts. If a "conflict" turns out to be a file you don't recognize (e.g. a skill that was never installed locally), treat upstream as the source of truth and write it in.
A legacy install (scaffolded before this command existed) has no manifest at .agents/skills/sw/.update-manifest.json. The first run degrades to 2-way: files equal to upstream report current; everything else reports conflict (the engine cannot tell "you edited it" from "upstream changed it" without a baseline). Merge those conflicts as above; the run writes a manifest, so the next update is fully 3-way and precise. Say this explicitly when you see an all-conflict first run.
