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 B, and why

skill-maker scanned grade B with 1 finding 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 2mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/compaction-template.sh, scripts/generate-skill.sh, scripts/validate-skill.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<execution_context>

  • Auto-load the style guide + compaction patterns at start (via <context> injection above)
  • Auto-execute scaffolding (mkdir + boilerplate writes) — these are reversible
  • ASK before writing the actual SKILL.md body — preview must be approved
  • ASK before deferring to Anthropic skill-creator for eval iteration — only if user opts in
  • Saved Rules: accumulate per-user-style preferences (e.g., "always wants Phase 5.5 deep-clean for stateful skills") in state.md
  • Rolling window: keep last 10 generated-skill entries full, compact older to one-line in archive section </execution_context>
  1. TaskCreate one task per phase (8 phases).
  2. Read state.md if exists; check for IN_PROGRESS marker.
  3. If IN_PROGRESS found → AskUserQuestion:
    • Resume from last checkpoint
    • Start fresh (archive previous as ABORTED)
    • Show full history (abort, let the user review)
  4. Otherwise → record current generation as IN_PROGRESS with checkpoint: INITIALIZED.
  5. Read references/skill-style.md + references/compaction-patterns.md into context (loaded via @ in <context> block above, but verify accessible).

TaskUpdate Phase 0 → completed.

What ships with it

17 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
