These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

health-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Health Check

Your Task

Run the health_check MCP tool and report results to the user.

Workflow

IMPORTANT: Do NOT use Bash for any step. Use only the tools listed below.

  1. Use the ToolSearch tool with query select:mcp__plugin_bitwize-music_bitwize-music-mcp__health_check to load the MCP tool schema
  2. Call mcp__plugin_bitwize-music_bitwize-music-mcp__health_check (the MCP tool, not a CLI command)
  3. Report results clearly using the format below

Report Format

All OK

HEALTH CHECK: OK
  Venv: N packages verified
  Skills: N skills registered
  Collisions: no album slug collisions

Warnings

HEALTH CHECK: WARN

VENV [warn]
  N outdated: pkg1 (1.0 -> 1.1), pkg2 (2.0 -> 2.1)
  N missing: pkg3, pkg4
  Fix: <the venv check's `fix` field from the health_check result> (already the correct command for the user's OS)

SKILLS [warn]
  N missing from Claude Code: skill-a, skill-b
  N ghost (deleted but cached): skill-c
  Fix: claude plugin update bitwize-music

COLLISIONS [warn]
  N album slug collision(s):
  slug-name: kept [genre-a], shadowed by [genre-b]
  Fix: Rename one album with /bitwize-music:rename or move its directory, then run rebuild_state

For comprehensive diagnostics, run the `diagnose` MCP tool.

Failure

HEALTH CHECK: FAIL

VENV [fail]
  Venv not found at ~/.bitwize-music/venv
  Fix: /bitwize-music:setup

Remember

  1. Be concise — this is a status report
  2. Show fix commands — always include the fix command when status is not ok
  3. Suggest diagnose — if warnings are found, mention diagnose MCP tool for deeper checks
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
