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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02947 | $0.02947 |
| Opus 5.5 | $0.01179 | $0.01179 |
| Sonnet 5.5 | $0.00589 | $0.00589 |
| Haiku 4.5 | $0.00295 | $0.00295 |
Grade A, and why
claude-code 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Context for Claude Code
CRITICAL RULES
NEVER use pkill or broad process-killing commands (like pkill -f "claudeup" or pkill -f "claude"). This kills all Claude CLI sessions running on the machine. Instead, ask the user to restart applications manually or close specific windows.

Key Architecture Decisions
1. Team-First Configuration
Shareable (committed to git):
- Project IDs, URLs, configuration
.claude/settings.jsonwith project config- No secrets
Private (environment variables):
- API tokens, credentials
- Each developer's
.envfile - Never committed
2. Smart Validation
Configuration commands check existing setup before asking questions, validate credentials before saving.
3. Project-Specific Installation
Plugins can be installed:
- Globally (all projects)
- Per-project (
.claude/settings.json) - Teams use project-specific for consistency
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.

claude-code CLAUDE.md is an instructions file published in the GitHub repository MadAppGang/claude-code (286 stars, last pushed 7mo ago), licensed MIT. It adds 2,947 tokens to every session, about $0.0118 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
