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 | $0.01571 | $0.01571 |
| Opus 5.5 | $0.00628 | $0.00628 |
| Sonnet 5.5 | $0.00314 | $0.00314 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade A, and why
claude-history 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.

Claude's Role: claude-history CLI Developer
Project Overview
claude-history is a Go CLI tool that provides programmatic access to Claude Code's agent history storage. It maps between filesystem paths and Claude's internal storage format, enabling querying, filtering, and export of conversation history including subagent sessions and tool calls.
Primary Responsibilities
- Maintain and extend the CLI tool - Add features, fix bugs, improve performance
- Ensure cross-platform compatibility - Windows, macOS, Linux support
- Write comprehensive tests - Unit tests for all new code (>80% coverage target)
- Follow Go best practices - Standard project layout, idiomatic Go code

Key Technical Details
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.

claude-history CLAUDE.md is an instructions file published in the GitHub repository randlee/claude-history (5 stars, last pushed 5mo ago), licensed MIT. It adds 1,571 tokens to every session, about $0.0063 per session on Opus 5.5. 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.
