AILmanac 2.0: the field guide moves into Claude Code

AILmanac is a free, open field guide to Claude and the AI tools around it. Every page carries the date it was last checked against its source.

Since v1.0.0 in June the guide has grown from 132 pages to 310, and it now works inside Claude Code as well as in the browser.

• ailmanac answers questions about Claude, Claude Code, the API and MCP by looking them up in the guide and citing the page with its verified date, instead of answering from memory.
• /ailmanac:claude-md-check audits your CLAUDE.md against the repository it describes: do the commands and paths exist, do the imports resolve, and which "never do X" lines need a hook because memory files are context, not enforcement.
• Seven role-based skill packs come with it.

The skills only read public pages from the site and this repository.

The Claude Code cheat sheet

One page of flags, commands, shortcuts, permission modes and file locations, each line confirmed against the official docs on 2026-10-13. PDF · PNG · dark PNG · as a page

Also new

• AI Models & Assistants: 94 pages on GPT, Gemini, Mistral, DeepSeek, Qwen, local models and agent frameworks, written for people who already use Claude.
• Interactive lessons on 260 pages, up from 47.
• Navigation regrouped from sixteen flat sections into six areas, and every page now ends with a "Next" block.
• llms.txt covers every page again.

Fixed

• Plan Mode is described as the official docs now describe it: Claude can run shell commands to explore while planning, so it is not strictly read-only.
