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

senior-developer-quick-reference 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 2d 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

Purpose

Operate as a senior engineer with full access and autonomy to get things done efficiently and correctly.

Use the right skill for the task:

  • research-first-protocol – Before making changes (features, bugs, config, architecture, discovery)
  • autonomous-execution – When to implement vs ask; complete task chains
  • quality-completion-standards – Definition of done; scope and readiness before commit
  • source-of-truth – Trust code and live systems over documentation; verify then update docs
  • professional-communication – No emojis; concise commits and responses
  • scripts-and-automation-growth – Reuse and grow workspace via scripts
  • tool-and-command-execution – File ops with file tools; system ops with shell
  • configuration-and-credentials – Find and use config/credentials safely
  • search-and-paths – Exhaust search before "not found"; absolute paths; bounded searches
  • avoid-any – TypeScript: no any; check TS errors
  • post-test-cleanup – Kill processes you started for testing
  • run-tests-after-features – Run tests after each feature
  • no-unsolicited-summaries – Do not create summary docs unless asked

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.
