If the user specifies tags, use those instead. + 2. DEDUPE: call `find_doc_issues` for %DOC_OWNER%/%DOC_REPO% and look for an open issue titled + "Found docs updates needed from %CODE_REPO% release to ". + - If it exists, note its issue number and call `find_pull_requests_for_issue` for it. If that + issue ALREADY has pull requests, STOP and report that it is already handled (issue + PR + URLs). If the issue exists but has NO pull requests, reuse it (skip step 8) and continue. + - If it does not exist, continue (you will create it in step 8). + 3. Call `get_changed_files` for %CODE_OWNER%/%CODE_REPO% with path_filter=%CODE_SOURCE_PATH_FILTER%. + 4. Filter the files: EXCLUDE tests and package-info / module-info. Prioritize newly added files + (whole new features) and public API surface (agents, tools, models, sessions, flows). + 5. UNDERSTAND each important change deeply before writing docs: + - Call `get_file_diff`, and `get_file_content` on the changed source file(s), to learn the new + API precisely (classes, functions, parameters, defaults, return types). + - Call `search_code` over %CODE_OWNER%/%CODE_REPO% (the code repo, e.g. its `examples/` and + tests) for REAL usage of the new API and read it with `get_file_content`, so your code + samples actually compile and are idiomatic. Never invent or guess API; verify against source. + 6. Find the doc(s) to update: `search_code` over %DOC_OWNER%/%DOC_REPO% (add `path:docs`) and + `get_file_content` to read the current page(s). Note how OTHER languages are documented there + (tabbed code blocks / per-language sections). Skip docs/api-reference/ (auto-generated). + 7. Decide the real documentation work for each change. Every recommendation must add real content, + for example: + - Add a complete %CODE_REPO% code example to the relevant page, mirroring the existing + Python/Java tabs or sections (add the language tab/section WITH working code). + - Add or expand conceptual prose explaining the feature and how to use it in this language. + - If the feature has NO page, CREATE a new page (full prose + example) at a sensible docs path. + - Update the language-support label/pill too, but ALWAYS together with the content above. + If NO documentation changes are warranted, create nothing and report that. + 8. Unless the issue already exists (step 2), create exactly ONE issue with `create_issue` for + %DOC_OWNER%/%DOC_REPO%: + - Title: "Found docs updates needed from %CODE_REPO% release to " + - Body: the compare link, then one section per recommendation: + ``` + ### N. Summary of the change + **Doc file(s)**: path/to/doc.md (or NEW: path/to/new_page.md) + **Content to add**: the prose + the actual code example to include + **Reasoning**: why this update is needed + **Reference**: path/to/source/file + ``` + 9. Then, for EACH recommendation, call `create_pull_request` for %DOC_OWNER%/%DOC_REPO%: + - base_branch="main". + - file_paths = the doc file(s); new_contents = the COMPLETE final content of each file, aligned + 1:1. Start from the current content (from `get_file_content`), ADD the new prose, code + examples and/or sections, and keep all existing content intact. For a NEW page, new_contents + is the entire new file. + - title = "Update docs for %CODE_REPO% : ". + - body = "Part of #" followed by the recommendation details. + + # 4. Rules + - Write REAL documentation: conceptual explanation + working, idiomatic code samples grounded in + the actual source and existing examples. A PR that only toggles a language pill is unacceptable. + - Preserve existing content: never delete or reformat unrelated content; ADD the new content and + mirror the page's existing structure (e.g. language tabs). Create new pages for undocumented + features. + - `create_issue`/`create_pull_request` either perform the action (returning a URL) or, in dry-run + mode, return a preview without writing anything.
