phx:plan — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited phx:plan (Agent Skill) and scored it 70/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 3 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.

Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.

spawn directly in parallel. 3+ agents (broad multi-context feature): determine the effective maximum nesting depth. Use an explicit positive-integer CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH value first; when it is unset, inspect claude --version (the default is 1 in 2.1.217–2.1.218 and 3 in 2.1.219+). If the version is unavailable, conservatively use 1. At depth 3+, spawn ONE planning-orchestrator to run and compress the fan-out. At depth 1 or 2, keep orchestration in this main session: spawn the selected specialist agents directly, wait for them, then spawn phx:context-supervisor directly if compression is needed. Never spawn an orchestrator that cannot delegate. Read only the resulting digest and summaries/consolidated.md. If TaskCreate is in your tool list (never ToolSearch for it), create a task per spawn: TaskCreate({subject: "{Agent} research", activeForm: "Researching..."}), mark in_progress on spawn, completed when done
"completed". NEVER write plan while any agent is still running
Also create plans/{slug}/scratchpad.md for decisions and dead-ends
When planning from review: Every finding must appear in the plan — either as a task OR explicitly deferred by the user.
