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 | $0.09612 | $0.09612 |
| Opus 5.5 | $0.03845 | $0.03845 |
| Sonnet 5.5 | $0.01922 | $0.01922 |
| Haiku 4.5 | $0.00961 | $0.00961 |
Grade A, and why
coco-workflow 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 17d 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 — 617 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md -- Coco
Project Overview
Coco is a Claude Code plugin that provides autonomous spec-driven development. It unifies planning (slash commands), execution (built-in task tracker), PR workflow with AI code review, and visibility (configurable issue tracker) into a single plugin distributed via the Claude Code marketplace (or as a git submodule).
Architecture
Five layers:
- Discovery:
/coco:prdand/coco:roadmapproduce PRD, analysis, and roadmap artifacts. Supports multi-repo via derived PRDs (/coco:prd derive) - Planning: Skills (
interview,design,tasks,import) produce spec artifacts inspecs/{feature}/ - Execution:
lib/tracker.sh(bash + jq) manages task state, dependencies, sessions - Review: Two-tier PR workflow with AI code review (
agents/code-reviewer.md) - Visibility: Issue tracker bridge (Linear MCP, GitHub CLI, or none) mirrors status

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.
