session-start — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited session-start (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.

Run the full session start procedure and report project status to the user.
You perform the 8-step session startup procedure that initializes a working session.

rebuild_state()Call the get_pending_migrations MCP tool. It compares the installed plugin version against last_migrated_version in state (the last version whose migrations were processed — distinct from plugin_version, which only records the installed version for display) and returns the pending notes already parsed and sorted.
reason: "current", or reason: "unknown" when theinstalled version can't be read from plugin.json): No action needed.
reason: "upgrade" or "untracked"): For eachmigration, process its actions in order:
auto: Execute silently (run check first — skip if it returns 0)action: Show description, ask the user to confirm before executinginfo: Display to the usermanual: Show the instruction to the useracknowledge_migrations (no argumentacknowledges everything up to the installed version) so the same notes do not surface again next session.
reason: "untracked"means the state predates migration tracking; the full backlog up to the installed version is surfaced once, then cleared byacknowledge_migrations. Do NOT just rebuild state to clear migrations — a rebuild preserves the pending status; onlyacknowledge_migrationsrecords that you processed them.
Skill model checking is no longer part of session start. Skills use tier aliases (opus/sonnet/haiku) that auto-track the frontier model, and the test suite (/bitwize-music:test) enforces model/effort hygiene — so no manual model checking is needed when new Claude models are released.
Using data from state.json, report:
From state.ideas.counts — show count by status (Pending, In Progress, etc.)
Filter state.albums for status: "In Progress", "Research Complete", "Complete"
For each, show:
From state.albums — find tracks where sources_verified is "Pending"
If any found, warn: "These tracks have unverified sources — generation is blocked until verified."
From state.session:
Based on state, show ONE relevant tip:
| Condition | Tip |
|---|---|
| No albums exist | "Try /bitwize-music:tutorial to create your first album" |
| Ideas exist but no albums | "You have album ideas! Use /bitwize-music:album-ideas list to review them" |
| In-progress albums exist | "Resume where you left off: /bitwize-music:resume <album-name>" |
| Overrides loaded | "Custom overrides loaded from {overrides}/" |
| Overrides missing | "Customize your workflow with override files — see /reference/overrides/" |
| Pending verifications | "Source verification needed before generation can proceed" |
Also show one random general tip (rotate through these):
