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-review-and-quality 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 9d 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 Review and Quality

Overview

Multi-dimensional code review with quality gates. Every change gets reviewed before merge — no exceptions. Review covers five axes: correctness, readability, architecture, security, and performance.

The approval standard: Approve a change when it definitely improves overall code health, even if it isn't perfect. Perfect code doesn't exist — the goal is continuous improvement. Don't block a change because it isn't exactly how you would have written it. If it improves the codebase and follows the project's conventions, approve it.

When to Use

  • Before merging any PR or change
  • After completing a feature implementation
  • When another agent or model produced code you need to evaluate
  • When refactoring existing code
  • After any bug fix (review both the fix and the regression test)

The Five-Axis Review

Every review evaluates code across these dimensions:

1. Correctness

Does the code do what it claims to do?

  • Does it match the spec or task requirements?
  • Are edge cases handled (null, empty, boundary values)?
  • Are error paths handled (not just the happy path)?
  • Does it pass all tests? Are the tests actually testing the right things?
  • Are there off-by-one errors, race conditions, or state inconsistencies?

2. Readability & Simplicity

Can another engineer (or agent) understand this code without the author explaining it?

  • Are names descriptive and consistent with project conventions? (No temp, data, result without context)
  • Is the control flow straightforward (avoid nested ternaries, deep callbacks)?
  • Is the code organized logically (related code grouped, clear module boundaries)?
  • Are there any "clever" tricks that should be simplified?
  • Could this be done in fewer lines? (1000 lines where 100 suffice is a failure)
  • Are abstractions earning their complexity? (Don't generalize until the third use case)
  • Would comments help clarify non-obvious intent? (But don't comment obvious code.)
  • Are there dead code artifacts: no-op variables (_unused), backwards-compat shims, or // removed comments?

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.
