e4ec9dc425 MUL-2802: add skill import conflict strategies (#3997)
* feat(skills): structured conflict + overwrite path for local skill re-import

Local-skill re-import previously failed (or silently skipped) on a same-name
collision and, on delete+reimport, changed the skill UUID and dropped agent
bindings. This adds a structured conflict result and a creator-only overwrite
write path so a re-import can update the existing skill in place.

- New terminal import status `conflict` carrying { existing_skill_id,
  existing_created_by, can_overwrite }; can_overwrite = requester is the
  skill creator (canOverwriteSkillByLocalImport — intentionally narrower than
  canManageSkill: admins edit in-app, not via re-import).
- Conflict is detected at daemon-report time (the effective name is only known
  once the bundle arrives) via GetSkillByWorkspaceAndName, with the unique
  constraint as a race backstop.
- Import requests carry action=overwrite + target_skill_id, persisted through
  both the in-memory and Redis LocalSkillImportStore (the heartbeat → daemon
  payload is unchanged; overwrite is resolved server-side).
- overwriteSkillWithFiles updates by target_skill_id in one tx: re-checks
  existence (workspace-scoped) and creator permission, then replaces
  description/content/config and fully replaces files (pruning files absent
  from the new bundle). Preserves id, created_by, created_at, name, and
  agent_skill bindings. Publishes skill:updated (not skill:created).
- Boundaries: target deleted or permission lost → failed (no fallback to
  create-by-name); any mid-write error rolls back the tx, leaving the original
  skill untouched. Retrying a terminal request is a no-op.

Tests cover: creator/non-creator conflict (can_overwrite), overwrite preserves
UUID + agent binding + prunes removed files, non-creator overwrite fails,
deleted target fails without create fallback, retry idempotency, and Redis
round-trip of the new fields.

Backend half of MUL-2701. Contract change: same-name local imports now return
status `conflict` instead of `failed` — the Desktop/core client must be updated
to consume it (sibling task).

* fix(skills): gate structured conflict behind client opt-in; guard overwrite target name

Addresses review feedback on PR #3498 (MUL-2800).

Backward compatibility: a same-name local import now returns the new `conflict`
status only when the initiating client opts in via `supports_conflict` (an
overwrite request implies it). Older clients — already-installed Desktop builds
whose poll loop only understands `failed`/`timeout` — keep the legacy `failed`
+ "a skill with this name already exists" behavior, so upgrading the backend
ahead of the client no longer regresses the import UX. This is the installed-app
API-compat boundary the repo's CLAUDE.md calls out.

Also: the overwrite write path now verifies the incoming effective name matches
the target skill's current name (errSkillOverwriteNameMismatch -> failed),
preventing a stale/wrong target_skill_id from writing one skill's content onto
another. Creator-only + workspace scoping already prevent privilege escalation;
this narrows the API so it can't be misused.

Refactored LocalSkillImportStore.Create to a LocalSkillImportRequestInput params
struct (the signature had grown to 8 positional args; the opt-in flag pushed it
over). supports_conflict is persisted in both the in-memory and Redis stores.

Tests: conflict tests now opt in; added a legacy-client test (no flag ->
failed + legacy message) and an overwrite name-mismatch test.

44feb3d06d fix(skill): canonicalize reserved SKILL.md path check across daemon + API (#3660)
A skill_file row whose path is the skill's own SKILL.md (persisted by
older builds or direct create/update API calls) collides with the
primary content the daemon writes itself, failing task prep with
errPathPreExists on every non-codex local runtime (#3489).

#3526 guarded this with strings.EqualFold(path, "SKILL.md") at the
daemon write site and the three API ingress points, but the stored path
is not canonicalized: "./SKILL.md" or "sub/../SKILL.md" slip past the
exact-match guard while filepath.Join still resolves them onto the same
SKILL.md, so prep can still break.

Extract one canonical helper, skill.IsReservedContentPath, that cleans
the path before the case-insensitive compare, and use it at all four
sites (execenv writeSkillFiles, skill create, update, single-file
upsert). Add a daemon-side regression test for writeSkillFiles ignoring
a bundled SKILL.md (exact + "./" spellings) — the load-bearing fix
previously had only API-layer coverage — plus a unit test for the helper.

Existing poisoned rows are intentionally left in place (skipped at prep)
per the decision on MUL-2928.

Follow-up to #3526; supersedes #3560.

623d29f276 feat(agents): one-click create from curated templates (Phase 1) (#2520)
* docs(agents): three-phase agent quick-create plan

Captures the full design for moving agent creation from manual form +
one-by-one skill attachment to a tiered experience:

- Phase 1 (this PR): one-click curated templates, AI-free.
- Phase 2 (next): AI-recommended skills via the existing quick-create
  task mechanism — no new server-side LLM dependency.
- Phase 3 (later): AI creates the whole agent end-to-end, composing
  Phase 2 with a new `multica agent create` CLI driver.

Documents the architectural decisions that keep all three phases on
existing infrastructure (no SSE, no server-side LLM SDK, no new WS
channels), the two soft blockers Phase 1 unlocks for later phases
(createSkillWithFiles TX composability + skill same-name dedupe), and
the scope decisions we explicitly opted out of (Anthropic plugin
marketplace, ClawHub UI affordances).

* fix(skills): harden import against invalid UTF-8 and binary files

PG rejects two byte patterns in a TEXT column. Both crashed real skill
imports we hit while assembling the template catalog:

- Embedded NUL (0x00) -> SQLSTATE 22021. Already stripped by
  sanitizeNullBytes, kept as-is.
- Other invalid UTF-8 (e.g. 0x91 — Windows-1252 smart quote in a skill
  whose author saved prose from Word). sanitizeNullBytes now also runs
  strings.ToValidUTF8 over the content so the second class no longer
  takes the whole import down.

For non-text payloads (images, fonts, archives, compiled binaries),
sanitization isn't the right fix — agents never read those as text,
and the bytes can't survive a TEXT column at all. addFile now skips
them by extension before the per-bundle cap counters tick, logging
the skip so an unexpected drop leaves a breadcrumb.

Function name kept for compatibility with the many call sites; both
behaviours are strict supersets of the original.

* refactor(skills): split createSkillWithFiles for tx composition + add workspace find-or-create query

Two soft blockers cleared so create-from-template (next commit) can
fold N skill creates and the agent + binding writes into one outer
transaction:

1. createSkillWithFiles used to Begin/Commit its own tx. Caller
   composition was impossible — N invocations meant N separate
   transactions and no atomicity over the whole materialise step.
   Pull the body into createSkillWithFilesInTx(ctx, qtx, input); the
   original function becomes a thin wrapper that manages its own tx
   for standalone callers. Existing call sites: zero behaviour change.

2. Add GetSkillByWorkspaceAndName sqlc query — workspace skill lookup
   by name, anchored to UNIQUE(workspace_id, name) from migration
   008. Lets the template materialiser implement find-or-create:
   reuse the workspace's existing skill row when a template
   references the same name, rather than crashing on the unique
   constraint or polluting the workspace with `<name>-2` clones.

* feat(agents): agent template catalog + create-from-template endpoint

Server-side foundation for Phase 1 of the quick-create roadmap (see
docs/agent-quick-create-plan.md). Adds:

- server/internal/agenttmpl/ — embed-loaded catalog of curated agent
  templates. Each template ships pre-written instructions plus a list
  of skill URLs that get materialised into the workspace at create
  time. Validation runs at startup (init() panics on a malformed
  template) so a bad JSON ships as a deploy-time defect, not a
  runtime 500. Slug must equal the filename basename so the URL
  router is mirror-symmetric with the file layout.

- 11 starter templates covering Engineering / Writing / Building /
  Testing (code-reviewer, frontend-builder, planner, docs-writer,
  one-pager, html-slides, full-stack-engineer, …).

- Three new endpoints, all behind RequireWorkspaceMember:
    GET  /api/agent-templates           — picker list (no instructions)
    GET  /api/agent-templates/:slug     — detail with instructions
    POST /api/agents/from-template      — materialise + create

  Create flow:
    1. Auth + runtime authorization happen BEFORE the GitHub fan-out
       so a 403 never wastes 20s of upstream fetches.
    2. Pre-flight dedupe by cached_name reuses workspace skills
       without an HTTP fetch — second create-from-the-same-template
       drops from 20s to <100ms.
    3. Parallel fetch (30s per-URL timeout) for the remaining skills.
    4. Single transaction: every skill insert, the agent insert, and
       the agent_skill bindings. On any upstream fetch failure the TX
       rolls back and the API returns 422 with `failed_urls` so the
       UI can name the bad source(s).
    5. extra_skill_ids (user-supplied additions) are verified through
       GetSkillInWorkspace per id before attach, so a malicious client
       can't graft a skill from another workspace via UUID guessing.

- multica agent create --from-template <slug> CLI flag dispatches to
  the new endpoint with a 60s ceiling, matching `multica skill import`.

* feat(agents): one-click create-from-template UI

Frontend half of Phase 1. CreateAgentDialog becomes a state machine
spanning four steps:

  chooser          → Start blank / From template cards
  blank-form       → existing manual form (post-chooser)
  duplicate-form   → existing form pre-filled from a duplicated agent
  template-picker  → grid of templates, click navigates to detail
  template-detail  → instructions + skill list preview + one-click Use

Picking a template never lands on the form: name auto-deduped against
existingAgentNames, runtime = first usable one, visibility = private.
Refinement happens on the agent detail page if needed. Same rationale
the doc spells out — templates exist precisely to skip configuration.

New components, all collapsible-by-default so quick-create stays fast:
  - template-picker.tsx — categorised grid, lucide icons + semantic
    accent tokens resolved through static maps so Tailwind's JIT picks
    up every variant (dynamic class strings would silently miss).
  - template-detail.tsx — instructions preview, skill list with cached
    descriptions, Use CTA. Renders the failedURLs banner when a 422
    fires — the only step that can trigger that response.
  - instructions-editor.tsx — collapsed preview-card / expanded full
    ContentEditor.
  - skill-multi-select.tsx + skill-picker-list.tsx — shared multi-
    select surface, also adopted by the existing skill-add-dialog.
  - avatar-picker.tsx — agent avatar upload, mirrors the inspector's
    visual language.

Schema-defended client (CLAUDE.md → API Response Compatibility): the
three new endpoints are wired through parseWithFallback with lenient
zod schemas. Desktop builds outlive any given server — a future
field rename / wrapping must not white-screen older installs.
listAgentTemplates accepts both the current bare array and a future
{templates: [...]} envelope. Coverage: 7 new schema-test cases in
schema.test.ts (null body, missing skills/instructions, malformed
create response, envelope migration).

Catalog + detail go through TanStack Query with staleTime: Infinity —
workspace-independent static data, no per-mount refetch.

Other:
- skill-add-dialog becomes a true multi-select (Confirm button +
  checkbox list); attached skills are filtered out of the list.
- agents-page hands the freshly-created Agent back to the dialog so a
  follow-up setAgentSkills can attach the form-selected skills.
- agent-overview-pane drops the mx-auto/max-w-2xl frame on config-
  tab content; the wider dialog visual language reads better with
  tabs filling the column.
- Every new UI string lives in both en/agents.json and
  zh-Hans/agents.json under create_dialog.* / tab_body.skills.* —
  locales/parity.test.ts blocks drift in CI.

* fix(ci): align skill import test + drop next-only lint suppression

- TestFetchFromSkillsSh_ResolvesRootLevelSkillMd now expects assets/logo.png
  to be skipped; matches the new addFile binary-extension guard
  (6fafd86e). The .png is intentionally dropped so PG TEXT inserts don't
  hit SQLSTATE 22021.
- packages/views shares zero next/* deps, so the @next/next/no-img-element
  eslint plugin isn't loaded there. The eslint-disable directive
  referencing it produced a hard "rule not found" error in CI lint. Raw
  <img> is the right primitive in views; remove the disable comment.

* test(agents): wrap CreateAgentDialog tests in workspace/navigation providers

The dialog now calls useNavigation() and useWorkspacePaths(), both of
which throw outside their providers. The existing tests rendered the
dialog bare and tripped both new requirements:

- NavigationProvider — supply a stub adapter so push() works for the
  agent-detail redirect.
- WorkspaceSlugProvider — useWorkspacePaths() requires a slug.

The blank-vs-template chooser is now the default first step; the
existing tests target the runtime picker on the manual form, so the
helper auto-clicks "Start blank" when no template is passed
(duplicate-mode tests skip the chooser).

Manual afterEach(cleanup) + document.body wipe. Base UI's Dialog
portal renders into document.body and leaves focus-guard/inert wrapper
divs behind across tests, so the second test in the suite saw two
"All" / "My Runtime" matches and getByText failed. The wipe is local
to this file rather than the shared setup because it isn't a global
issue — only suites that open Base UI dialogs hit it.

f628e48775 refactor(server): error-returning ParseUUID to prevent silent data loss
* refactor(server): make ParseUUID error-returning to prevent silent data loss (MUL-1410)

util.ParseUUID previously swallowed errors and returned a zero pgtype.UUID
on invalid input. When this zero UUID reached a write query (DELETE/UPDATE),
the SQL matched zero rows and the handler returned 2xx success — producing
silent data corruption. #1661 (DeleteIssue with identifier-style ID) was the
visible symptom; PR #1680 patched that one site, this commit closes the
class of bug.

Changes:

- util.ParseUUID now returns (pgtype.UUID, error). Add util.MustParseUUID
  for trusted round-trips that should panic on invalid input.
- handler/handler.go: parseUUID wrapper now calls MustParseUUID — any
  unguarded user-input string reaching it surfaces as a recovered panic
  (chi middleware.Recoverer → 500) instead of silently corrupting data.
  Add parseUUIDOrBadRequest(w, s, fieldName) for handler entry points.
- Convert every Queries.Delete*/Update* call site reachable from raw user
  input (autopilot, comment, project, skill, skill_file, label, pin,
  attachment, feedback, issue assignee, daemon runtime, workspace) to
  validate UUIDs explicitly with parseUUIDOrBadRequest, returning 400 on
  invalid input. Where a resolved entity.ID is already in scope, write
  queries now use it directly instead of re-parsing the URL string.
- Update getWorkspaceMember + loadIssueForUser to handle invalid UUIDs
  gracefully (404/400 instead of panic).
- Update util/middleware/cmd-level callers (subscriber_listeners,
  notification_listeners, activity_listeners, scope_authorizer,
  middleware/workspace) to use the error-returning API.
- Add server/internal/util/pgx_test.go covering valid/invalid input and
  the MustParseUUID panic contract.
- Add TestDeleteIssueByIdentifier + TestDeleteIssueRejectsInvalidUUID
  regression tests in handler_test.go (the original #1661 bug + the
  invalid-input case).
- Document the handler UUID parsing convention in CLAUDE.md so the rule
  is enforceable in future PR review.

* fix(server): address GPT-Boy review of #1748

P1 fixes from PR #1748 review:

1. Migrate remaining request-boundary UUIDs to parseUUIDOrBadRequest so
   malformed input returns 400 instead of panic/500. Was missing on:
   - issue.go: workspace_id in CreateIssue/ChildIssueProgress/ListIssues/
     SearchIssues/BatchUpdateIssues/BatchDeleteIssues; project_id /
     parent_issue_id / lead_id / assignee_id / assignee_ids / creator_id
     filters; batch issue_ids and assignee/parent/project fields in
     BatchUpdateIssues (skip on bad input via util.ParseUUID, matching
     the existing per-row continue semantics).
   - project.go: project id + workspace_id in GetProject/UpdateProject/
     DeleteProject; lead_id in CreateProject/UpdateProject;
     workspace_id in ListProjects + SearchProjects.
   - handler.go: resolveActor now uses util.ParseUUID for X-Agent-ID /
     X-Task-ID headers; invalid UUID falls back to "member" (matches
     pre-existing semantics) instead of panicking.
   - issue.go: validateAssigneePair returns 400 on invalid workspace_id
     instead of panicking.

2. Fix issue:deleted WS event payloads to emit uuidToString(issue.ID)
   instead of the raw URL string. After an identifier-path delete
   ("MUL-7"), the previous payload would have leaked the identifier to
   subscribers, leaving stale entries in frontend caches that key by
   UUID. Updated DeleteIssue (issue.go:1341) and BatchDeleteIssues
   (issue.go:1641). The slog "issue deleted" log line also now records
   the resolved UUID so logs match the WS payload.

3. Extend TestDeleteIssueByIdentifier to subscribe to the bus and
   assert issue:deleted.payload.issue_id is the resolved UUID, not
   the identifier.

* fix(server): validate remaining reviewed UUID inputs

* fix(server): validate remaining handler UUID inputs

* fix(server): finish request boundary UUID audit

* fix(server): validate remaining request body UUIDs

* fix(server): validate runtime path UUIDs

* fix(server): validate remaining audit UUID inputs
