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 | $0.01872 | $0.01872 |
| Opus 5 | $0.00936 | $0.00936 |
| Sonnet 5 | $0.00374 | $0.00374 |
| Haiku 4.5 | $0.00187 | $0.00187 |
Grade A, and why
claude-skills 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 11d 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 — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Configuration
This file contains project-specific intelligence and configuration for Claude Code sessions.
Memory Bank System
This project uses a Memory Bank system to maintain context across sessions. All memory files are stored in .claude/memory-bank/ and should be read at the start of every conversation.
Core Memory Files (Read these in order):
- memory-rules.md - System documentation
- projectbrief.md - Foundation document
- productContext.md - Product vision
- systemPatterns.md - Architecture patterns
- techContext.md - Technical setup
- activeContext.md - Current work focus
- progress.md - Status tracking
Elegance Demand
For non-trivial changes, pause and ask yourself: is there a more elegant solution? If your plan feels hacky, step back and rebuild it properly. Elegant code is simple, clear, and does not fight the architecture.
If you encounter pre-existing issues in code you're touching, be a good citizen and clean them up too. Leave the codebase better than you found it.
Instructions for Claude
On Every Session Start:
- Read all core memory bank files in the order listed above
- Verify understanding of current context
- Check activeContext.md for immediate priorities
- Review progress.md to understand what's complete and what's pending
When User Says "update memory bank":
- Review ALL memory bank files (mandatory - don't skip any)
- Update files that need changes based on recent work
- Pay special attention to activeContext.md and progress.md
- Document any new patterns discovered
- Update project intelligence in this file if needed
Planning Mode (via /plan command):
- Read Memory Bank (automatic)
- Verify context completeness
- Ask 4-6 clarifying questions based on findings
- Draft comprehensive plan
- Get user approval
- Implement systematically
Project Intelligence
This section grows as patterns and preferences are discovered during work on this project.
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-skills CLAUDE.md is an instructions file published in the GitHub repository Smirnov-Labs/claude-skills (5 stars, last pushed 2mo ago), licensed MIT. It adds 1,872 tokens to every session, about $0.0094 per session on Opus 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 2026-08-31.
