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 | $0.00082 | $0.00082 |
| Opus 5.5 | $0.00033 | $0.00033 |
| Sonnet 5.5 | $0.00016 | $0.00016 |
| Haiku 4.5 | $0.00008 | $0.00008 |
Grade A, and why
Fullstack-development-agent-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 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.

Claude-Specific Notes
- Prefer skills with explicit verification and exit criteria.
- Keep changes incremental and evidence-backed.
- Use starter packs to reduce ambiguity on new tasks.
- For framework work, route to
skill-packs/after core skills inskills/. - See
docs/fullstack-skills-catalog.mdfor the full 106-skill inventory.
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.

Fullstack-development-agent-skills CLAUDE.md is an instructions file published in the GitHub repository vaquarkhan/Fullstack-development-agent-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
