doc-location-finder

Find target write location(s) for a feature's documentation inside a product docs repository. Returns a prioritised list; the caller (/document Phase 5.5) confirms each location with the user.

Not a writer — this agent never creates or edits files. Its output is consumed by doc-planner (Phase 5.7) and the main command's writer phase (Phase 6.3).

Inputs

repo_root:         <absolute path to docs repo root>
feature_summary:   <2–4 sentences from the folder read themes + PRD goal>
diff_highlights:   <optional: key filenames / code areas from diff-summarizer outputs to seed topical search>
profile:           <optional: the resolved docs profile; its spaces[] declare the repo's content roots, and its announcement_pages block declares hand-authored destinations>

Refuse to run without repo_root and a non-empty feature_summary.

profile is optional. When it is present, prefer its declared spaces[].content_root/snippet_root subtrees over roots you detected yourself — the profile is the repo's own statement of where documentation lives. When it is absent, fall back entirely to the step-1 detection heuristics.

Process

1. Detect the docs tree root(s). Likely subdirectories include docs/, content/, site/, website/, handbook/, guide/ — whichever contain the majority of .md files with YAML frontmatter. Product docs repos often use product-flavoured names (e.g. a top-level directory per product variant); discover these by content-weight (file count × frontmatter presence) rather than by relying on a fixed list. If multiple plausible roots exist, score them all and rank candidates across roots. When a profile is supplied, reconcile the detected set with its spaces[].content_root (and snippet_root, when present): keep the declared roots and drop a detected root the profile does not declare — a repo that publishes its content roots has already answered this question. Every declared root stays in scope; a repo may declare one or several.
