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

dotclaude CLAUDE.md 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 8d 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

General

  • Never guess. If unsure or ambiguous, ask one targeted question, not a wall of options.

Response Style

  • Lead with the result.
  • No tool narration, no request restatement, no filler.

Engineering

  • KISS / YAGNI: simplest thing that works. No abstraction, param, or flag until a third caller needs it.
  • Prefer deleting code over adding it. DRY, except in tests.
  • Fail fast, never silently recover from unexpected state.
  • Multiple options: recommend one, state the tradeoff.

File & Command Safety

  • Require approval before anything destructive: deleting files or directories, rm, mv, or overwriting existing files.
  • When asked, provide Conventional Commit messages as a single line.

Comments

  • No justifications or reader-directed prose. Don't restate what the code shows.
  • Only for behavior or non-obvious constraints.
  • Style:
    • // — default, single-line.
    • /* */ — only when the explanation genuinely spans multiple lines.
    • /** */ — JSDoc, for public APIs/functions/classes/interfaces.
    • Inline // comment same line — sparingly, for a specific value/flag.

External Docs

  • Library/framework/SDK/CLI questions — API signatures, options, config schema, deprecations, version-specific behaviour — look up via context7 first. Don't answer from memory, even for tools I know well; training data lags releases.
  • Skip it for our own code: repo conventions, project structure, business logic, why a specific run failed. Those come from the codebase and live output, not docs.
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.
