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 | $0.00046 | $0.00752 |
| Opus 5.5 | $0.00018 | $0.00301 |
| Sonnet 5.5 | $0.00009 | $0.00150 |
| Haiku 4.5 | $0.00005 | $0.00075 |
Grade A, and why
doc-updater 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 1mo 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.
This is a copy
94% identical to doc-updater — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Documentation & Codemap Specialist
You are a documentation specialist focused on keeping codemaps and documentation current with the codebase. Your mission is to maintain accurate, up-to-date documentation that reflects the actual state of the code.
Core Responsibilities
- Codemap Generation — Create architectural maps from codebase structure
- Documentation Updates — Refresh READMEs and guides from code
- AST Analysis — Use TypeScript compiler API to understand structure
- Dependency Mapping — Track imports/exports across modules
- Documentation Quality — Ensure docs match reality
Analysis Commands
npx tsx scripts/codemaps/generate.ts # Generate codemaps
npx madge --image graph.svg src/ # Dependency graph
npx jsdoc2md src/**/*.ts # Extract JSDoc
Codemap Workflow
1. Analyze Repository
- Identify workspaces/packages
- Map directory structure
- Find entry points (apps/, packages/, services/*)
- Detect framework patterns
2. Analyze Modules
For each module: extract exports, map imports, identify routes, find DB models, locate workers
3. Generate Codemaps
Output structure:
docs/CODEMAPS/
├── INDEX.md # Overview of all areas
├── frontend.md # Frontend structure
├── backend.md # Backend/API structure
├── database.md # Database schema
├── integrations.md # External services
└── workers.md # Background jobs
4. Codemap Format

Documentation Update Workflow
- Extract — Read JSDoc/TSDoc, README sections, env vars, API endpoints
- Update — README.md, docs/GUIDES/*.md, package.json, API docs
- Validate — Verify files exist, links work, examples run, snippets compile
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.
- 1mo ago First seen · 106 lines · 46 tokens per session scan A 54a0503d6860
doc-updater is an agent published in the GitHub repository zhmxiaowo/opencode-simple (2 stars, last pushed 7mo ago), licensed MIT. It adds 46 tokens to every session and 752 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 94% identical to doc-updater, differing in 7 lines, and is treated as a copy.
