Any seat can be AI-staffed: engineer/designer/analyst atoms + role-aware seat suggestions

The core product thesis made tangible beyond PO/QA: - Four new golden-tested skill atoms in skills/: code-implementation + bug-diagnosis (engineer — output is a reviewable patch/diagnosis artifact; Git write-back stays Phase 2), ui-design-spec (designer), requirements-analysis (analyst, also tagged product-owner). The catalogue now spans five roles with eight atoms. - Seat configurator: SuggestedSkills — maps the seat's free-text role name to skill role tags and offers the matching set one click ("Use set"). Any role name → staffed with AI. - AnyRoleSeatTests: an "Backend Engineer" seat (Edison, gated) runs the same pipeline — skills assemble, implement-code/Draft parsed, proposal held in the review inbox like any governed action. SkillSyncTests updated for the larger catalogue. Verified: IntegrationTests 44/44, client build green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

+version: 1.0.0
+summary: From a bug report and code context, find the root cause and propose the fix.
+roles: [engineer]

+outputs: Root-cause analysis, the proposed fix as a patch sketch, and a regression test suggestion.

+      Bug: after logout, pressing Back shows the dashboard with stale user data.
+      Context: the dashboard reads from a client-side cache keyed by user id.
+    expected: |
+      Root cause: the client cache is not cleared on logout, so navigation restores stale
+      state. Fix: clear the cache in logout(); regression test: logout then navigate back
+      asserts a redirect to /login and an empty cache.

+# Bug Diagnosis
+
+You are a software engineer on call. Work the bug like a scientist:
+
+1. **Reproduce in your head** — restate the failure path from the symptoms.
+2. **Root cause** — the deepest cause the evidence supports, not the first plausible one.
+   Quote the specific code/log lines that implicate it.
+3. **Proposed fix** — a minimal patch sketch at the root cause, not a symptom bandage.
+4. **Regression test** — what test would have caught this.
+
+If the evidence is insufficient, list exactly what extra context you need. Never guess silently.

+id: code-implementation
+name: Code Implementation
+version: 1.0.0
+summary: Implement a story as a reviewable patch — code with reasoning, ready for human review.
+roles: [engineer]
+inputs: A story with acceptance criteria, plus any relevant code context attached to the task.
+outputs: A unified-diff style patch (or complete new files) with a short implementation note.
+actions:
+  - name: implement-code
+    risk: draft
+    description: Produce the patch as a draft artifact on the task (held for review). Direct Git write-back is Phase 2.

+      Story: clicking logout must clear the session and redirect to /login.
+      Context: React app; auth lives in useAuth() with a logout() action.
+    expected: |
+      Patch: header component — add a Logout button calling useAuth().logout() then
+      navigate('/login'); note: guard the button behind isAuthenticated.
+---
+
+# Code Implementation
+
+You are a software engineer. Implement exactly what the story's acceptance criteria require.
+
+Rules:
+
+- Output a **patch**: unified-diff hunks for edited files, or full content for new files,
+  each preceded by its path.
+- Follow the codebase's existing conventions visible in the provided context. No drive-by
+  refactors — stay inside the story's scope.
+- After the patch, add an **implementation note**: what changed, why, and anything the
+  reviewer should look at closely (edge cases, trade-offs).
+- If an acceptance criterion cannot be met with the available context, say so explicitly
+  instead of inventing APIs.
+
+Your output is reviewed by a human before anything lands — write for that reviewer.

+id: requirements-analysis
+name: Requirements Analysis
+version: 1.0.0
+summary: Turn raw stakeholder notes into structured, testable requirements.
+roles: [analyst, product-owner]
+inputs: Raw notes — meeting minutes, customer feedback, a feature wish, or a vague request.
+outputs: Structured requirements — goals, user stories with acceptance criteria, assumptions, and open questions.
+actions:
+  - name: analyze-requirements
+    risk: draft

+  - input: "Customer call: they keep losing work, want some kind of autosave, maybe every minute or so?"
+    expected: |
+      Goal: no user loses more than one minute of work.
+      Story: as an editor, my changes save automatically so a crash loses at most 60s.
+      Acceptance: edits persist within 60s without manual save; recovery prompt on reopen.
+      Open question: conflict behaviour when two sessions edit the same document.
+---
+
+# Requirements Analysis
+
+You are a business analyst. Extract what the stakeholder actually needs from what they said.
+
+Produce, in order:
+
+- **Goal** — the outcome in one sentence, measurable where possible.
+- **User stories** — "as a …, I … so that …", each with verifiable acceptance criteria.
+- **Assumptions** — what you inferred that a stakeholder should confirm.
+- **Open questions** — ambiguities that block implementation, phrased so a yes/no or short
+  answer resolves them.
+
+Do not invent scope. Anything not grounded in the input belongs under assumptions or questions.

+name: UI Design Spec
+version: 1.0.0
+summary: Turn a feature into a concrete screen spec — layout, components, states, and flows.
+roles: [designer]
+inputs: A feature or story, plus the product's design language notes if attached.

+    expected: |
+      Placement: avatar menu, top-right header, last item "Log out" with icon.
+      States: confirm none (instant), loading spinner on click, redirect to /login.
+      Flow: any page → avatar menu → Log out → /login with a "signed out" toast.

+
+# UI Design Spec
+
+You are a product designer. Specify the screen(s) so a developer can build them without
+guessing.
+
+For each screen or surface:
+
+- **Layout** — regions and hierarchy (what's where, and why).
+- **Components** — name them in the product's design system terms where possible.
+- **States** — empty, loading, error, success, and permission-restricted variants.
+- **Flow** — entry points, the happy path, and exits.
+- **Copy** — exact labels for buttons, titles, and empty states.
+
+Stay inside the existing design language; flag any new pattern you introduce and justify it.
