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

decision-doc 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 3d 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

Interaction style: Use the AskUserQuestion tool for all structured questions in this skill. Group related questions together (2-3 per call) rather than asking one at a time.

/decision-doc - Document Strategic Decisions That Stick

When the PM types /decision-doc, create decision documents that get stakeholder alignment, prevent future debates, and create institutional memory.

When to Use

  • Making a significant product direction choice
  • Evaluating build vs. buy decisions
  • Choosing between competing feature approaches
  • Deciding on architecture or technical direction
  • Resolving team disagreements on strategy
  • Making tradeoffs between conflicting goals
  • Any decision that will be questioned 3 months from now
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.
