dep-bootstrap — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited dep-bootstrap (Agent Skill) and scored it 65/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 3 high-severity and 6 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.

```See INSTALL.md — review scripts/bootstrap.sh (sha-pinned) before running it yourself.The text {match} is the classic direct prompt-injection phrasing. Placed in a skill body that the agent reads as trusted instructions, it tries to make the agent abandon its prior rules and follow whatever comes next — a full system-prompt override.

The primary manifest — the file an agent reads to learn what this artifact does.
This skill ships real dependency manifests beside SKILL.md. None of them is a runtime command — they are declarations the old line rules (which need an install verb or a public-IP literal) never see. They are discovered structurally, by filename:
install time), plus a git dep, a bare user/repo shorthand, an off-registry tarball URL, and wide-open version pins.
redirect, a non-TLS source, and a bare unpinned package.
bare unpinned package.
Every manifest above carries a non-registry source, an install-lifecycle script, or a wide-open pin — each a supply-chain vector the registry's signing/audit is supposed to gate. Pre-1.6.0 the scanner scored this directory 🟢 GREEN (exit 0, zero findings) — the silent false negative Phase F closes.
Expected verdict after Phase F: 🔴 RED (CR039 + HI023 + ME012).
