description: Apply one change request across the whole jsc skill set — multiple skills in multiple domains in one pass. Sync every domain repo from the Gitea canonical marketplace while the decision tree asks the change details, apply the change per affected domain via parallel sub agents, re-check against the guidelines checklist until it passes, open a PR per affected repo via jsc-git pr, then deploy and verify per references/deploy-verify.md from a fresh CLI process, and append the change report to wiki SKILLSET_{HASH}. Use when a change spans multiple skills or domains; not for a single skill (use skill-update).

# skillset-update — apply one change across the skill set

Single source of guidelines: [`../../references/guidelines.md`](../../references/guidelines.md).

## Flow

1. Start `tools/sync-domains.sh` and the change-details decision tree **in parallel** — the sync touches no answer the tree needs, and the tree's answers change nothing the sync does, so waiting for one before the other only adds idle time.
   1. Run `tools/sync-domains.sh` to sync every domain repo of the Gitea canonical marketplace. Exit 0 is the only code that means every repo is present and current; keep the `domain<TAB>path` rows. Exit 3 means some repos were not updated: reconcile every path named on stderr (commit or stash the dirty tree, or fix the failing pull) and rerun; when the user confirms a dirty tree is intentional local work, record that decision and continue on the local version — never read exit 3 as current. Exit 2 means a domain could not be cloned. Exit 1 means the root could not be derived, `gitea.sh` was not found, or the canonical marketplace was unreadable; when stderr says the root could not be derived, set `JSC_PLUGINS_ROOT` to the directory that holds the domain repos and rerun, because under a plugin install the script sits in the CLI's plugin cache and its built-in guess lands there instead of the domain workspace. Resolve 2 and 1 before continuing.
   2. Ask for the change details via the `jsc-ask:ask` decision tree: what rule or behavior changes, which skills and which domains are affected. Include three required checks before the affected-skill list is final: whether any deterministic input/output flow must move to `tools/`, whether any detailed flow must run as a sub agent, and whether any wiki or Gitea flow must read inherited environment variables before asking the user. Every option states its impact scope (example: changing a shared flow step touches every skill that calls it). These three are a shaping guardrail asked before any file is touched; keep asking them even when a later step would catch the same problem.

   Completion condition: the `domain<TAB>path` rows are in hand, and the affected-skill list plus the three checks are agreed with the user.
2. Apply the change to every affected skill — the modification part MUST run as a sub agent, one sub agent per affected domain repo, and those sub agents **run in parallel**: each repo's files are independent. Every sub agent also updates its own repo's `references/behaviors.md` in the same pass: a changed behavior rewrites that skill's `## {name}` section, a new skill gets a section inserted in dictionary order, a removed skill loses its section. Keep all five rows filled — 觸發時機、關鍵步驟、外部呼叫、完成條件、可驗證跡象. Each repo's behavior list ships in that repo's own PR, so no cross-repo PR pair has to be merged in order. Then run `tools/sync-skill-manifest.sh {domain-path}` directly (no sub agent needed) for each affected domain repo to sync that domain README's 「Skills 目錄」 section and bump the version in all three manifests; these runs are independent per repo and may also go in parallel. Route each exit code: 0 — the README block and all three manifests are synced; 1 — the domain path, `skills/`, `README.md`, the `JSC-SKILLS` markers, a `SKILL.md`, a manifest, or a manifest `version` field is missing, so fix the named cause on stderr and rerun; 2 — usage error, the script takes exactly one argument; any other code — the script runs under `set -e`, so treat it as an environment fault and stop, never as a successful sync. Completion condition: every affected domain repo carries the change, its behavior-list update, the README sync, and the manifest bump.
3. Check every item of the guidelines.md audit checklist for each touched skill — one sub agent per affected domain repo, run in parallel. Each sub agent runs `tools/check-behaviors.sh {domain-path}` for the behavior-list item of its own repo instead of comparing by eye, and routes each exit code: 0 — that repo's list matches its `skills/` and all five rows are filled; 1 — every mismatch is printed on stderr as `{檔案}:{技能名}:{說明}`, so fix each one and rerun; 2 — usage error, the tool takes exactly one argument; 3 — nothing was checked, because `references/behaviors.md` is missing, `skills/` is missing, or no `SKILL.md` was found, so create the missing file and rerun. **Exit 3 is never a pass.** On any failure, **return to step 1.2**: ask again and fix, until all items pass. Completion condition: every checklist item passes for every touched skill, and `tools/check-behaviors.sh` exits 0 for every affected domain repo.
4. Call `jsc-git:pr` once per affected domain repo to open a Push Request. Completion condition: every affected repo has a PR URL, and all URLs are reported in one table with the format in [`../../references/pr-report.md`](../../references/pr-report.md).
5. Deploy the batch change, verify it runs, then report:
   1. Follow [`../../references/deploy-verify.md`](../../references/deploy-verify.md) from section 1 to section 5, once per affected domain repo — the route judgements run in parallel. The batch takes the deploy route only when **every** affected repo's `tools/deploy-route.sh` exits 0; a single exit 3 puts the whole batch on the worktree route, because the change reaches the CLIs only when the last repo merges, so name every outstanding release PR. The verification then runs in a **fresh CLI process**, never in the session that ran the deploy: that session raised the restart gate itself and still holds the old skill bodies. Verify every touched skill's row in `tools/list-skills.sh`, every tool this change touched, and one minimal prompt per affected domain per checkable CLI — the per-CLI and per-domain prompts run in parallel. Completion condition: every completion condition in `deploy-verify.md` sections 1 to 5 holds for every affected domain repo.
   2. Write the change report to the wiki — this part MUST run as a sub agent, one sub agent per affected domain repo, run in parallel. Each sub agent writes two pages in two repos, and they must not be mixed up.
      - **Content page `SKILLSET_{HASH}`.** Resolve its repo with `jsc-gitea/tools/gitea.sh wiki-repo SKILLSET`, which reads `JSC_WIKI_REPO_SKILLSET` first, then `JSC_WIKI_REPO`. `{HASH}` is `gitea.sh hash-id "{owner}/{repo}"` of that repo, used at the full 40 characters it prints. Write it through `jsc-gitea:wiki` following [`../../templates/skillset-page.md`](../../templates/skillset-page.md): **append** a section for this change — date, 「批次更新」, the change request in one line, touched skills, changed files, PR URL, the step 5.1 route verdict and verification result per item — and keep every earlier section.
      - **Directory page `SKILLSET_CONTENTS`.** One shared page holds every domain's row, so each sub agent writes only its own. It lives in the CONTENTS repo, never in the SKILLSET one: `wiki-contents.sh` resolves it itself with `gitea.sh wiki-repo CONTENTS`, whose chain is `JSC_WIKI_REPO_CONTENTS` then `JSC_WIKI_REPO` and never falls back to `JSC_WIKI_REPO_SKILLSET`. Build one file holding the single row from [`../../templates/skillset-contents.md`](../../templates/skillset-contents.md), its 異動頁 cell carrying the **absolute** URL from `gitea.sh wiki-url {SKILLSET repo} SKILLSET_{HASH}` — `[[SKILLSET_{HASH}]]` resolves only inside the directory page's own wiki, so it would be a dead link. Then run:

        `jsc-gitea/tools/wiki-contents.sh upsert SKILLSET 2 "{owner}/{repo}" {row file} templates/skillset-contents.md`

        The key column is `2`, the 存取庫 column, holding that repo's `{owner}/{repo}` exactly as the row file writes it, so one domain keeps exactly one row and no sibling sub agent's row moves. Never hand-edit the directory page, and never overwrite it as a whole. Write the content page first and fetch the URL only after it exists.
      - **Exit codes.** Route every one of them:

        | Call | Exit | Do |
        | --- | --- | --- |
        | `gitea.sh wiki-repo` | 2 | The page type was misspelled. Fix the argument and rerun |
        | | 3 | No wiki repo is configured for that type. Name the variable (`JSC_WIKI_REPO_SKILLSET` for the content page, `JSC_WIKI_REPO_CONTENTS` for the directory page) and `JSC_WIKI_REPO`, ask per the `jsc-ask:ask` rules, then rerun |
        | `gitea.sh hash-id` | 1 | No SHA-1 helper on this machine. Stop and report that `sha1sum` or `shasum` has to be installed, and never hand-compute the hash |
        | | 2 | Empty input, so the `{owner}/{repo}` was never resolved. Fix that first |
        | Content page read | 0 | Append into the sections already there |
        | | 4 | The page does not exist yet, so build it from `templates/skillset-page.md` |
        | | 7 or 8 | Stop and write nothing: a page rebuilt on top of an unread read loses every section already on it |
        | `gitea.sh wiki-url` | 4 | The content page is not there, so the write above did **not** succeed. Go back and write it, and add no directory row until the page exists |
        | | 5 | The API answered with no `html_url`. Stop and report it; never assemble the URL by hand from the host and the page name |
        | `wiki-contents.sh upsert` | 0 | The row is in place. Report the `updated` or `added` it printed |
        | | 1 | The write failed. Report `SKILLSET_CONTENTS` as not written, together with the row content |
        | | 2 | An argument was rejected. Fix it and rerun; nothing was written |
        | | 3 | No CONTENTS wiki repo is configured. Report `JSC_WIKI_REPO_CONTENTS` and `JSC_WIKI_REPO` as the two variables to set; the new section is on `SKILLSET_{HASH}` and stays there |
        | | 4 | The directory page is absent and no template was passed. Rerun with `templates/skillset-contents.md` as the fifth argument |
        | | 7 | The token is invalid or lacks permission, so the other domains' rows are unknown. Stop, report the token problem, and create no page |
        | | 8 | Some other API failure. Stop, report that status, and create no page |

      On any failure, hand the page name and the unwritten entry back to the user and leave this step open; never close the flow on an unwritten report. Completion condition: every affected repo's `SKILLSET_{HASH}` holds the new section plus all earlier sections, and every one of those repos has a row on `SKILLSET_CONTENTS` written by a `wiki-contents.sh upsert` that exited 0, linking its page by absolute URL.
