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

skill-trace-enable 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 6d 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

Skill Trace Enable

Enable skill tracing using the skrills MCP server.

Use the mcp__plugin_skrills_skrills__enable-skill-trace tool with:

  • target: claude, codex, or both (default: both)
  • instrument: Add markers to skill files (default: true)
  • backup: Create .bak files before modifying (default: true)
  • dry_run: Preview without changes

Parse $ARGUMENTS for:

  • --target <target> or -t <target>: Target CLI (default: both)
  • --dry-run or -n: Preview mode
  • --no-backup: Skip backup when enabling

Report:

  • Skills instrumented
  • Backup files created (if applicable)
  • How to view traces after enabling

Handle errors:

  • If target invalid: List valid options (claude, codex, both)
  • If skills already instrumented: Report current state, skip re-instrumentation
  • If backup fails: Abort and report which file failed

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.
