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 | $0.00942 | $0.00942 |
| Opus 5 | $0.00471 | $0.00471 |
| Sonnet 5 | $0.00188 | $0.00188 |
| Haiku 4.5 | $0.00094 | $0.00094 |
Grade C, and why
skeleton CLAUDE.md scanned grade C with 2 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 7d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Expected in a hook, worth knowing in a rule or an instructions file.
- **Best approach:** Use cross-platform code that doesn't need output suppression (e.g., `subprocess.DEVNULL` in Python, `stdio: 'ignore'` in Node.js). This is a copy
88% identical to skeleton AGENTS.md — 12 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.

Critical Development Rules
These rules prevent recurring bugs documented in TODO.md and LESSONS_LEARNED.md:
1. KISS and DRY
- KISS: Only add what's requested or clearly necessary. No premature optimization or abstraction.
- DRY: Extract common patterns to shared functions. Use config files for repeated values.
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.

skeleton CLAUDE.md is an instructions file published in the GitHub repository alexwoo-awso/skeleton (1 stars, last pushed 6mo ago), licensed MIT. It adds 942 tokens to every session, about $0.0047 per session on Opus 5. A static security scan graded it C with 2 findings (hidden instructions, runs shell commands). It is 88% identical to skeleton AGENTS.md, differing in 12 lines, and is treated as a copy.
