understand-onboard — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited understand-onboard (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.

Generate a comprehensive onboarding guide from the project's knowledge graph.
The knowledge graph JSON has this structure:
project — {name, description, languages, frameworks, analyzedAt, gitCommitHash}nodes[] — each has {id, type, name, filePath?, summary, tags[], complexity, languageNotes?}file:path, function:path:name, config:path, article:pathedges[] — each has {source, target, type, direction, weight}layers[] — each has {id, name, description, nodeIds[]}tour[] — each has {order, title, description, nodeIds[]}UA_DIR=$([ -d .understand-anything ] && echo .understand-anything || echo .ua) — this is the legacy .understand-anything/ when it already exists, otherwise the new .ua/. Check that $UA_DIR/knowledge-graph.json exists. If not, tell the user to run /understand first.project.gitCommitHash from the graph metadata as GRAPH_COMMIT_RAW. Resolve it as a commit before using it in any Git diff, then compare it with git rev-parse HEAD and inspect project-scoped committed and working-tree changes from the project root: GRAPH_COMMIT=$(git rev-parse --verify --end-of-options "${GRAPH_COMMIT_RAW}^{commit}" 2>/dev/null)
