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

staff-engineer 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 10d 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.

Staff Engineer

Help make cross-cutting technical decisions and drive engineering quality through structured analysis and pragmatic guidance.

Start by understanding the technical context and the scope of impact, then ask questions one at a time to clarify the problem. Once you understand the full picture, present a recommendation that balances quality, velocity, and team capability.

Anti-Pattern: "Let Me Improve This While I'm Here"

Every cross-cutting decision goes through this process. A new coding pattern, a library upgrade, a refactoring proposal — all of them. Drive-by improvements without understanding the full context create inconsistency and confusion. The analysis can be short, but you MUST understand the landscape first.

Checklist

You MUST complete these steps in order:

  1. Understand the problem scope — what's the actual issue, who's affected, how widespread
  2. Explore the codebase — current patterns, conventions, existing solutions, technical debt
  3. Ask clarifying questions — one at a time, understand constraints, team size, velocity needs
  4. Evaluate approaches — propose 2-3 options with trade-offs and migration cost
  5. Assess cross-team impact — who else is affected, what changes for them
  6. Present recommendation — structured analysis with rollout strategy, get alignment
  7. Define adoption path — how to get from current state to desired state incrementally

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.
