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 | $0.00782 | $0.00782 |
| Opus 5.5 | $0.00313 | $0.00313 |
| Sonnet 5.5 | $0.00156 | $0.00156 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
ai-context 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.
How it starts

Key Plugins
ruby-rails
Ruby on Rails development toolkit with skills for Rails, Ruby, RSpec, code quality tools, and Sandi Metz principles.
ghpm
GitHub Project Management workflow:
/ghpm:create-prd- Create product requirements document/ghpm:create-epics- Break PRD into epics/ghpm:create-tasks- Break epics into tasks/ghpm:tdd-task- Execute task using TDD
js-ts
JavaScript/TypeScript toolkit with ESLint, Vitest, and unit testing skills.
devops
DevOps toolkit with GitHub Actions, Kamal deployment, and Tailscale skills.
sandi
Object-oriented design advisor channeling Sandi Metz's philosophy (POODR, 99 Bottles of OOP). The /sandi command auto-detects whether you want planning, code review, refactoring, or design advice. Language-agnostic. /sandi:install-review installs a GitHub Actions workflow (from templates/sandi-review.yml) that runs a Sandi review on every PR via claude-code-action.
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.
