llms.txt

This page tells a coding agent where rb’s documentation is, in the forms an agent reads best.

If you are an agent working in a repository with a .rb/ folder, start with rb context --model <your model id>, not with these pages: it is the state of the work, and it replaces anyone’s summary of it.

These docs, as text

Address	What it is
/docs/llms.txt	An index of every page of these docs, with a one-line description each.
/docs/llms-full.txt	Every page of these docs but the Changelog, in one plain-text Markdown file.

rabbitbrain.ai/llms.txt is rb’s own summary for agents: what the record is, the rules an agent follows, and what it must pass on to the user.

Built into rb

The manual ships inside every rb, so it always matches the installed version:

rb docs            # the whole manual: every rule, every command, the JSON envelope, every error and its fix
rb docs --start    # the protocol for starting the record in a project already under way
rb docs --errors   # the error table
rb skill           # the skill rb installs for coding agents

Over MCP (rb mcp), the same manual is the resource rb://docs, beside rb://start, rb://context, rb://status, rb://schema and rb://format.

What an agent must not do

• Compute a finding, an error, a ranking or a regression itself: record the numbers, and read the finding with rb show.
• Edit .rb/ by hand.
• Record a call the user did not ask for, or run rb confirm, which only the user runs, in their own terminal.
• Set or unset RB_ACTOR or RB_HUB_TOKEN, or read the credentials file rb login writes. See Auth.
