Content outside the markers is sacred — never modify it. ## Marker contract Only one marker pair is recognised: ``` ``` If the markers are missing, you do **not** insert them silently — defer to the `init` action (see below). ## INVOCATION ```json { "action": "sync", "project_root": "/path/to/project", "wiki_root": "/path/to/project/docs/my-app-wiki" } ``` | Action | Behaviour | |---|---| | `sync` (default) | Drift-check + LLM salvage + write new block. | | `check` | Drift-check only — no writes. Use for `--dry-run`. | | `init` | Insert markers when missing AND `ecosystem.readme.insert_markers_on_init: true`. Takes optional `quickstart_depth` to seed the placeholder. | ## OUTPUT FORMAT The agent always emits a single JSON object on stdout. The shape varies by outcome: ### Success — sync wrote new content ```json { "status": "success", "action": "sync", "drift_summary": { "only_in_readme_count": 3, "only_in_getting_started_count": 1, "shared_count": 4 }, "salvaged_paragraphs": [ { "snippet": "Note: Node 21+ isn't supported...", "disposition": "keep_verbatim" } ], "written": "/path/to/project/README.md" } ``` ### Success — check (dry-run); no writes Same shape as `sync` success, with `action: "check"` and `written` omitted. ### Success — init inserted markers ```json { "status": "success", "action": "init", "written": "/path/to/project/README.md", "anchor": "## Install" } ``` ### No-op — init found markers already present ```json { "status": "noop", "reason": "markers already present" } ``` ### Skipped — init declined to act ```json { "status": "skipped", "reason": "disabled" | "no readme" | "insert disabled" } ``` ### Warn — sync/check found markers missing or corrupt ```json { "status": "warn", "error_code": "MARKERS_MISSING" | "MARKERS_CORRUPT", "message": "..." } ``` ### Error — fatal failure ```json { "status": "error", "error_code": "README_MISSING" | "GETTING_STARTED_MISSING" | "MARKERS_CORRUPT", "message": "..." } ``` ## Procedure for `sync` and `check` 1. Resolve `quickstart_depth` from `/wiki.config.yaml` → `ecosystem.readme.quickstart_depth` (`minimal`, `standard`, or `generous`; default `generous`). 2. Resolve `salvage_mode` from `ecosystem.readme.salvage_mode` (defaults to `autonomy.mode`; `auto` maps to `autonomous`). 3. Read `/README.md`. Extract the contents between `` and ``. Use `node agents/wiki-readme-agent/scripts/readme_sync.js extract --readme /README.md` to do this safely. 4. If the markers are missing or unbalanced, return `{status: "warn", error_code: "MARKERS_MISSING" | "MARKERS_CORRUPT", ...}` and do nothing else. 5. Read `/wiki/getting-started.md`. 6. Produce a paragraph-level drift report. For each paragraph (non-empty block separated by blank lines): - Classify as `only_in_readme`, `only_in_getting_started`, or `shared` (using semantic similarity, not text equality — paragraphs that mean the same thing in different words are `shared`). 7. For each `only_in_readme` paragraph, decide a salvage disposition: - `keep_verbatim` — paragraph is unique and current; retain at its current spot. - `keep_reworded` — paragraph has unique value but overlaps with `only_in_getting_started`; rephrase to merge. - `drop_outdated` — paragraph contradicts current wiki state. - `drop_duplicate` — paragraph is already covered by getting-started content (semantic match). - `escalate` — disposition is genuinely ambiguous. 8. Handle `escalate` per `salvage_mode`: - `conservative`: ask the user via `AskUserQuestion`. - `balanced` / `autonomous`: pick `keep_verbatim` and note in the drift report. 9. Construct the new quickstart block from the `quickstart_depth` template: - `minimal`: 1 install command + 1 first command (≈5 lines). - `standard`: install + first command + 2-3 follow-up bullets + 1 docs link (≈15 lines). - `generous`: numbered walkthrough mirroring `wiki/getting-started.md` TL;DR + steps 1-4, with code blocks (≈30 lines). **CRITICAL — link target rule.** Any "deeper docs" / "full walkthrough" link in the generated block MUST point to a file that is **tracked by git** (committed to the repo). Resolve in this priority order: 1. `docs/getting-started.md` if present AND tracked. 2. `docs//getting-started.md` if tracked (the wiki tree is gitignored by default; an existing local file does NOT prove it's tracked). 3. The project's `README.md` itself, with no follow-up link, if neither (1) nor (2) is tracked. **Verify tracked status with `git -C ls-files --error-unmatch ` (exit 0 → tracked).** The `-C ` flag is REQUIRED — `git ls-files` interprets pathspecs relative to the caller's current working directory, and the agent may not be running from the repo root, so an unqualified `git ls-files --error-unmatch docs/getting-started.md` from a subdirectory would falsely report the file as untracked. Do NOT use `git check-ignore` — it only reports gitignore matches and silently passes for untracked-but-unignored files, so a fresh clone or GitHub view would see a dead link. Never link to `wiki/getting-started.md` or `/wiki/getting-started.md` — those paths are wiki-internal and gitignored. 10. Splice salvaged paragraphs into the appropriate template slot (or append as `> **Notes**` at the end if no slot fits). 11. For `sync`: write the new block via `node agents/wiki-readme-agent/scripts/readme_sync.js write --readme /README.md --block-file `. 12. For `check`: skip step 11. 13. Return: ```json { "status": "success", "action": "sync" | "check", "drift_summary": { "only_in_readme_count": 3, "only_in_getting_started_count": 1, "shared_count": 4 }, "salvaged_paragraphs": [ { "snippet": "Note: Node 21+ isn't supported...", "disposition": "keep_verbatim" } ], "written": "/path/to/project/README.md" } ``` (`written` is omitted on `check`.) ## Procedure for `init` 1. If `ecosystem.readme.enabled: false`, return `{status: "skipped", reason: "disabled"}`. 2. If `/README.md` does not exist, return `{status: "skipped", reason: "no readme"}`. 3. Use `node agents/wiki-readme-agent/scripts/readme_sync.js extract --readme /README.md` to check for markers. If present, return `{status: "noop"}`. 4. If `ecosystem.readme.insert_markers_on_init: false`, return `{status: "skipped", reason: "insert disabled"}`. 5. Use `node agents/wiki-readme-agent/scripts/readme_sync.js init --readme /README.md --depth ` to insert markers after the install section heading (or after the first `## ` heading if no install heading is found). 6. Return `{status: "success", action: "init", written: "/path/to/project/README.md", anchor: "## Install"}`. ## Errors | `error_code` | Meaning | |---|---| | `MARKERS_MISSING` | README has no `wiki-managed: quickstart start` / `end` pair. | | `MARKERS_CORRUPT` | Unbalanced markers (e.g. start without end). | | `README_MISSING` | `/README.md` does not exist. | | `GETTING_STARTED_MISSING` | `/wiki/getting-started.md` does not exist. | | `BLOCK_FILE_MISSING` | The `--block-file` argument to the `write` subcommand points to a file that does not exist. |
