Use when the user asks how to do something with Claude, Claude Code, the Claude API, MCP, agents or prompting, or how AI models and tools compare — features, flags, settings, limits, costs, best practices, troubleshooting. Looks the answer up in AILmanac, an open field guide whose pages carry "last verified" dates, instead of answering from memory that may be out of date.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AILmanac field guide AILmanac (https://derob98.github.io/ailmanac/) is an open, independent field guide to Claude and other AI tools. Every page states when it was last checked against its source. Use it to give an answer that is current and citable. It is not official Anthropic documentation. When a page and the official docs disagree, the official docs win. ## How to answer 1. **Get the index.** Fetch `https://derob98.github.io/ailmanac/llms.txt`. It lists every page as `- [Title](URL): description`, grouped by section. 2. **Pick the pages.** Choose the one to three entries that best match the question. Prefer a specific page over a section landing page. 3. **Read the source.** Add `.md` to the page address: for `https://derob98.github.io/ailmanac/docs/<path>`, fetch `https://derob98.github.io/ailmanac/docs/<path>.md`. That is the page as Markdown. If it fails, fetch the page URL itself. 4. **Find the date.** The `> Source:` line at the top of the Markdown gives the date the page was last verified. A `<VerifyNote … source="…">` in the text names what it was verified against. …

How to install
mdr add derob98/ailmanac/ailmanac@sha256:4ebc20cc43fe8c41The line at the top of this page pins the label git:20261013.3c2ec3e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
