skill-delete

Remove a skill from the jsc skill set safely. Pick the skill from the Gitea canonical marketplace skill list, inventory every file referencing it, fix each affected file through decision-tree questions in parallel sub agents until guideline checks pass, delete the skill, open a PR via jsc-git pr, then deploy per references/deploy-verify.md and verify from a fresh CLI process that no on-disk leftover remains, and append the change report to wiki SKILLSET_{HASH}. Use only for removal; not for renaming (use skill-update).

skill-delete — delete a skill

Single source of guidelines: ../../references/guidelines.md.

Flow

1. Run tools/sync-domains.sh to sync every domain repo of the Gitea canonical marketplace. Completion condition: the script exits 0 and prints one domain<TAB>path line per marketplace domain — exit 0 is the only code that means every repo is present and current. 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. Run tools/list-skills.sh and present its domain / name / description rows to the user. The tool prints skills, not domains, so read the domain column to prove coverage. Exit 1 means the root could not be derived, the domain list was unreadable, or no skill was found — read stderr, fix the named cause (JSC_PLUGINS_ROOT for the root case, as in step 1) and rerun; never read it as an empty skill set. Completion condition: the script exits 0 and every domain printed by step 1 appears in at least one row; a domain with no row means its repo is missing or holds no skill — return to step 1 for that domain.

3. Let the user pick the skill to delete. Options state the impact scope: which skills reference it, and that its command stops working after deletion. Completion condition: one {domain}/{name} pair is confirmed for deletion.

4. Inventory every file related to the skill: run tools/find-skill-refs.sh {domain} {name} to list every file that references the skill name or its /jsc-{domain}:{name} command form, across every marketplace domain repo on this machine (covers other SKILL.md files, the domain README's 「Skills 目錄」 section, the two marketplace.json files in plugins/meta plus their synced copies in every domain repo, tools/, and the jsc-hooks wiring). The skill-name pattern is a bare substring match, so the list also carries other skills whose name starts with the same word plus plain prose — treat it as candidates to read, not as files that must change. Exit 0 means hits were printed; exit 1 means a clean zero-hit scan; exit 2 means a usage error, so fix the two arguments and rerun; exit 3 means the scan never ran — the root could not be derived, the domain list was unreadable, no domain repo is on this machine, or grep failed. Read stderr and fix the named cause; when it names the root, set JSC_PLUGINS_ROOT to the directory that holds the domain repos, because under a plugin install the script sits in the CLI's plugin cache and its built-in guess lands there. Never read exit 3 as zero hits — a failed scan taken as "no references" makes this skill skip files it must fix. Completion condition: the tool's file list is captured as the step 5 inventory.

5. Fix every file in the step 4 inventory. For each file:

   1. Read the file and decide whether it needs a fix to keep its current behavior after the deletion. If no fix is needed, record it as no-fix-needed with the reason and skip the rest of this loop. Completion condition: the file carries a recorded verdict — needs-fix or no-fix-needed with a reason.
   2. Ask for fix details via the jsc-ask:ask decision tree (call a replacement skill? move a deterministic input/output flow to tools/? run the detailed flow as a sub agent? drop the feature too?). If the fix touches wiki or Gitea access, confirm it reads inherited environment variables before asking the user. Every option states its impact scope. Completion condition: every question has a recorded answer.
   3. Apply the confirmed fix, then check the guidelines.md audit checklist for the file — the per-file fix work 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, so serialising them only adds waiting. Each sub agent reports one line per file: the path and either the applied fix or「無需修正」with the reason. On any checklist failure, return to step 5.2. Completion condition: the fix is in the file and every checklist item passes for it.

   Completion condition: every file in the step 4 inventory is marked either fixed-with-a-clean-checklist or explicitly no-fix-needed with a reason — no file is left without a verdict.

6. Delete the skill directory skills/{name}/ and remove that skill's ## {name} section from references/behaviors.md — the whole section, its table included, leaving every other section untouched. Both deletions ship in this same PR: a behavior list still carrying a deleted skill fails the domain's next audit, and the extra section is exactly what check-behaviors.sh reports. Then run tools/sync-skill-manifest.sh {domain-path} directly (no sub agent needed) to sync the domain README and bump the version in all three manifests. 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 remaining 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.

   Then run tools/check-behaviors.sh {domain-path} and route each exit code: 0 — the remaining sections match the remaining skills; 1 — every mismatch is printed on stderr as {檔案}:{技能名}:{說明}, so fix each one and rerun, the deleted skill's leftover section included; 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 fix the named cause and rerun. Exit 3 is never a pass.

   Completion condition: the directory is gone, references/behaviors.md holds no ## {name} section for the deleted skill, tools/check-behaviors.sh {domain-path} exits 0, the README's 「Skills 目錄」 no longer lists the skill, and all three manifests show the same new version.

7. Call jsc-git:pr to open a Push Request. Completion condition: a PR URL comes back and is reported with the table format in ../../references/pr-report.md.

8. Deploy the deletion, verify it took, then report:

   1. Follow ../../references/deploy-verify.md from section 1 to section 5: tools/deploy-route.sh {domain-path} picks the route, the deploy route or the worktree route runs, and 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 set, so verifying inside it either gets blocked or passes on stale behavior. On the worktree route, add that the skill stays installed and stays callable until the outstanding release PR merges. Completion condition: every completion condition in deploy-verify.md sections 1 to 5 holds for this domain repo.

   2. Verify the deletion concretely, on top of the deploy-verify.md items:

      • tools/list-skills.sh prints no row carrying the deleted {domain}/{name}.
      • Deep-delete verification. Run tools/verify-skill-removed.sh {domain} {name}; it detects the installed CLIs and greps each one's skill cache and hook config. Route each exit code: exit 0 — no leftover in the locations listed on stderr; exit 1 — leftovers printed as {file}:{line}:{content}, so remove every one by hand and rerun; exit 2 — usage error, fix the two arguments and rerun; exit 3 — nothing was checkable, because the root could not be derived, detect-clis.sh was not found, no CLI was detected, or no config location exists. The script printed no leftover because it looked nowhere, so exit 3 is never clean: report「無處可查」with the reason from stderr, and carry that sentence into step 8.3's wiki section and the final report, so nobody later reads the deletion as verified on disk. This is the only place the deep-delete check runs — running it before the PR only scanned a deletion that had not been deployed yet, so it always came back clean and proved nothing.
      • Every tool and skill that step 5 fixed still finishes with its documented exit code — a fix that broke a caller shows up here, not earlier.
      • One minimal prompt per checkable CLI, each in its own fresh process and all in parallel, confirming /jsc-{domain}:{name} is gone or that the replacement path still works.

      On any mismatch — the deleted skill still listed, a leftover from exit 1, a fixed caller that now fails, a prompt failure, or unexpected stderr — fix the cause and rerun this step from 8.1. Completion condition: the skill is absent from the list, the verification script exits 0 or its exit 3 is reported as「無處可查」and carried into step 8.3, every fixed caller ran, every checkable CLI completed the prompt with the expected result, and every untestable CLI has a stated reason.

   3. Write the change report to the wiki — this part MUST run as a sub agent. It is 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 the domain repo that lost the skill, used at the full 40 characters it prints. Write it through jsc-gitea:wiki following ../../templates/skillset-page.md: append a section for this change — date, 「刪除」, skill name, changed files (the step 5 inventory verdicts included), PR URL, the step 8.1 route verdict and the step 8.2 verification result per item, the deep-delete verdict「無處可查」included when it applies — and keep every earlier section.

      • Directory page SKILLSET_CONTENTS. 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, its 異動頁 cell written as [SKILLSET_{HASH}]({url}) with the absolute URL from gitea.sh wiki-url {SKILLSET repo} SKILLSET_{HASH}. Every link on both pages takes that [{text}]({url}) form; the double-bracket wiki-link form resolves only inside one wiki, so it is never used. 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 other domain's row moves. Never hand-edit the directory page. Write the content page first and fetch the URL only after it exists.

      • Check the links before writing. Hand every URL going onto the content page and into the directory row to jsc-gitea/tools/link-check.sh, and write only when it exits 0. It verifies through the Gitea API, never a web status code: a private repo answers 404 to an unauthenticated web request, so a status-code check would call a live page dead.

      • 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
        link-check.sh	0	Every link is reachable. Write the page
        	1	At least one link is dead. Write nothing, and report the DEAD lines it printed
        	2	No URL was passed, which is a defect here. Pass the links and rerun
        	3	GITEA_HOST is unset. Set it and rerun; never skip the check instead
        	7	Gitea authentication failed. Stop and report the key problem, and never read it as a dead link
        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: SKILLSET_{HASH} holds the new section plus all earlier sections, and wiki-contents.sh upsert exited 0 with this domain's row on SKILLSET_CONTENTS linking that page by absolute URL.
