Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00060 | $0.02422 |
| Opus 5 | $0.00030 | $0.01211 |
| Sonnet 5 | $0.00012 | $0.00484 |
| Haiku 4.5 | $0.00006 | $0.00242 |
Grade A, and why
sync-docs 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 2d 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 — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sync Documentation Guides
Synchronize the Elixir SDK documentation guides in docs/guides/ with the official Claude Agent SDK documentation.
Overview
Each guide in docs/guides/ mirrors an official Agent SDK documentation page. The guides show Elixir SDK equivalents of the official examples — never Python or TypeScript. This skill provides a systematic workflow to detect content drift and update guides when the official docs change.
Guide Conventions
All guides follow rules defined in docs/guides/CLAUDE.md. Key rules:
- Use full module names in prose (e.g.,
ClaudeCode.Stream.final_result/1) - Use
ClaudeCode.query/2for one-off examples; reserveClaudeCode.start_link/1+ClaudeCode.stream/3for streaming/multi-turn - Pattern match directly in
fnclauses - Follow official structure closely but prioritize idiomatic Elixir/OTP
- Include Elixir-only guidance where it applies
- Mark incomplete sections with callouts
Guide titles must be concise (1-3 words) for sidebar navigation. Prefer "File Checkpointing" over "Rewind file changes with checkpointing". Do NOT adopt verbose titles from the official docs — keep titles short even if the official page uses a longer name.
Each guide starts with:
# Concise Title
Subtitle describing the guide.
> **Official Documentation:** This guide is based on the [official Claude Agent SDK documentation](https://platform.claude.com/docs/en/agent-sdk/PAGE). Examples are adapted for Elixir.

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.
- 2d ago First seen · 225 lines · 60 tokens per session scan A 472c9141120e
sync-docs is a skill published in the GitHub repository guess/claude_code (96 stars, last pushed 2mo ago), licensed MIT. It adds 60 tokens to every session and 2,422 once invoked, about $0.0003 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 2026-08-30.
