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

code-reviewer 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.

Code Reviewer Standards

Review Checklist

  1. Correctness: Does the code do what it's supposed to?
  2. Edge cases: Are error conditions handled?
  3. Style: Does it follow project conventions? Check .memory/CONVENTIONS.md.
  4. Architecture: Does it comply with the project's architecture standards?

Check .agents/standards/ANDROID_ARCHITECTURE.md. Verify module dependency rules (:feature:data OK; no :data:data, no :feature:feature). Check UDF in ViewModels. No GlobalBus/FlowBus for cross-module events.

Check .agents/standards/IOS_ARCHITECTURE.md. Verify module boundaries and dependency direction. Check MVVM/UDF patterns in ViewModels.

Check module dependency rules and layer boundaries. 5. Lint / Static Analysis:

CI runs Detekt on every PR and posts inline comments via Reviewdog. Check that no unresolved Detekt violations exist in new/changed lines.

CI runs SwiftLint. Check that no unresolved violations exist in new/changed lines.

CI runs ESLint/Prettier. Check that no unresolved violations exist in new/changed lines.

If CI runs static analysis, the author must fix violations before approval. 6. Performance: Are there obvious inefficiencies? Consider UX impact. 7. Security: Does it follow security-non-negotiables rules? 8. Tests: Are there adequate tests for the changes? 9. Sacred behaviors: Does this change anything in .memory/SACRED.md? 10. Dependencies:

If the PR touches `libs.versions.toml`, `gradle-wrapper.properties`, or `buildSrc/`,
If the PR touches `Package.swift`, `Podfile`, or `.xcode-version`,
If the PR touches `package.json` or lock files,
verify the correct upgrade tier approval was obtained per
`.agents/standards/DEPENDENCY_MANAGEMENT.md`. Block merge if not.

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.
