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 | $0.00259 | $0.00259 |
| Opus 5.5 | $0.00104 | $0.00104 |
| Sonnet 5.5 | $0.00052 | $0.00052 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
ai-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 2mo 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.
What it actually says
Claude Code Instructions for AI Agent Skills
When working with skills in this repository:
- Read the SKILL.md fully before applying any skill
- Follow process steps in order — do not skip or reorder
- Complete verification gates at each step before proceeding
- Surface assumptions — state what you're assuming before coding
- Don't overcomplicate — minimum code that satisfies the spec
Available Slash Commands
/skill-add— Scaffold a new skill from the template/skill-validate— Validate a skill file has all required sections/skill-apply <name>— Apply a specific skill to the current task/skill-list— List all available skills
Skill Application Protocol
When a skill applies to your current task:
- State which skill you're applying and why
- Follow the Process steps exactly
- Complete each verification check before moving on
- Report evidence at the end (test output, build logs, etc.)
Anti-Patterns to Avoid
- Skipping the "Think Before Coding" phase
- Writing tests after the fact instead of alongside
- Making changes beyond the scope of the current task
- Merging without verification evidence
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.
