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

revise-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 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.

Origin

This is a copy

100% identical to revise-claude-md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Review this session for learnings about working with Claude Code in this codebase. Update CLAUDE.md with context that would help future Claude sessions be more effective.

Step 1: Reflect

What context was missing that would have helped Claude work more effectively?

  • Bash commands that were used or discovered
  • Code style patterns followed
  • Testing approaches that worked
  • Environment/configuration quirks
  • Warnings or gotchas encountered

Step 2: Find CLAUDE.md Files

find . -name "CLAUDE.md" -o -name ".claude.local.md" 2>/dev/null | head -20

Decide where each addition belongs:

  • CLAUDE.md - Team-shared (checked into git)
  • .claude.local.md - Personal/local only (gitignored)

Step 3: Draft Additions

Keep it concise - one line per concept. CLAUDE.md is part of the prompt, so brevity matters.

Format: <command or pattern> - <brief description>

Avoid:

  • Verbose explanations
  • Obvious information
  • One-off fixes unlikely to recur

Step 4: Show Proposed Changes

For each addition:

### Update: ./CLAUDE.md

**Why:** [one-line reason]

\`\`\`diff
+ [the addition - keep it brief]
\`\`\`

Step 5: Apply with Approval

Ask if the user wants to apply the changes. Only edit files they approve.

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.
