phx:recall — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited phx:recall (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.
Search three evidence layers, cheapest first, to answer "have we solved this before?". Stop at the first layer that answers the question.
/phx:recall how did we fix the LiveView form that saved silently?
/phx:recall what did we decide about the billing context boundaries?
/phx:recall which library did we pick for rate limiting and why?session transcripts. Don't fetch sessions when a solution doc answers
get_session_messages responsesare 3–15KB each. Spawn a subagent per session that writes a summary file and exits; NEVER batch multiple session fetches into one context
path, commit hash, or session date + match snippet). No vague "we did this once"
say so once and use the fallback layers; never error out
Run Grep with keywords from the question over .claude/solutions/. Treat a hit here as the best answer — it was written for exactly this purpose. Present it and stop unless the user wants more.
git log --oneline --grep="{keyword}" -i -20 # commit messages
git log -S "{code-symbol}" --oneline -10 # when a symbol changed
git log --follow --oneline -10 -- {file} # one file's history
git show {hash} --stat # inspect a candidateUse -S (pickaxe) when the question names code; --grep when it names intent. Show matching commits with one-line context each.
Check for mcp__ccrider__* tools (load via ToolSearch if deferred).
If absent: report "ccrider MCP not connected — answered from solution docs + git history" and stop after Layers 1–2.
If present:
mcp__ccrider__search_sessions with the question's key phrases —returns ranked hits with session IDs and snippets
(or ask, if genuinely ambiguous)
mcp__ccrider__get_session_messages, extract only what answers '{question}', write ≤30 lines to .claude/recall/{id}.md" (Iron Law 2)
Present the answer with its evidence trail. If the recalled knowledge was NOT already in .claude/solutions/, offer /phx:compound so the next recall stops at Layer 1.
