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 | $0.00735 | $0.00735 |
| Opus 5 | $0.00367 | $0.00367 |
| Sonnet 5 | $0.00147 | $0.00147 |
| Haiku 4.5 | $0.00073 | $0.00073 |
Grade A, and why
deliberate 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 8d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Deliberate
Engineering discipline for AI harnesses. A drop-in skill library for LLM coding agents.

Every skill lives at skills/<name>/SKILL.md with YAML frontmatter (name, description). This structure is required for compatibility with npx skills add angad-kandhari/deliberate (vercel-labs/skills CLI).
The repo doubles as a Claude Code plugin: .claude-plugin/plugin.json marks it a plugin (the existing skills/ folder is auto-discovered), .claude-plugin/marketplace.json makes it installable via /plugin marketplace add angad-kandhari/deliberate, and hooks/hooks.json wires a SessionStart hook that cats hooks/activation.md into context so the skills actually activate. The activation hook is the fix for the ecosystem-wide "instruction dropout" problem — passive skills fire only ~6–44% of the time without it.
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.

deliberate CLAUDE.md is an instructions file published in the GitHub repository angad-kandhari/deliberate (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 735 tokens to every session, about $0.0037 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.
