# docs-generate-agents-md — Generate AGENTS.md from a Docsbook workspace ## Workflow 1. Gather the workspace settings. If a Docsbook workspace is connected, read them directly; otherwise derive them from local files (docs config, repo) or ask the user. 2. Collect: docs URL (custom domain or computed), docs path, enabled languages, AI chat status, and plan tier. If a workspace is expected but does not exist, instruct the user to run `/docs-setup-workspace` first. 3. Read the doc tree / page list — from a graph tool if a workspace is connected, or by walking the docs folder — to extract top-level folder structure and total page count. If it is unavailable, continue with an empty structure — the template handles missing data. 4. Render the AGENTS.md template using the collected data: site URL, owner/repo, docs path, languages, AI-chat status, folder structure summary. 5. Write the file to the repo root. If AGENTS.md already exists, locate the managed section by its markers and replace only that section. If no markers exist, append under them. Never touch content outside the markers. 6. Report the file path, Docsbook URL, languages, and AI chat status. Remind the user to commit the file. ## Guardrails - Never overwrite content outside the managed section markers. - If the workspace is missing, do not attempt to create it — redirect to `/docs-setup-workspace`. - If the doc tree is unavailable (no workspace connected, plan restriction, or empty folder), continue with an empty s
