Skills move from a global Git-only registry to a per-company library that orgs author and
version in-app — Git stays as the shared *starter* library.
Domain & persistence:
- Skill gains OrganizationId (null = shared builtin, visible to every org), Origin
(Builtin | Authored | Installed), AuthoredByMemberId. Identity is now
(OrganizationId, SkillKey, Version); the unique index uses NULLS NOT DISTINCT so builtins
stay unique by key+version while each org gets its own namespace (and can fork a builtin).
AddSkillOwnership migration backfills existing rows as Builtin.
- Owned GoldenExample rows are cloned in Skill.Index so a fork can't re-parent the source's
tracked entities.
Authoring (tenant, dynamic):
- POST /api/skills/authored — structured fields → same indexer pipeline (embedding +
publish gate apply identically), tagged org + author. POST /api/skills/{key}/fork copies a
builtin/global skill into your org as an editable Authored draft. List/Get are org-scoped
(your org + shared builtins). New Capability.ManageSkills (Owner + TeamOwner), audited.
- GET /api/skills/marketplace: read-only seam listing public skills across orgs (install is
the next step).
Security (from adversarial review — two confirmed criticals):
- Managing shared builtins is an operator action, not a tenant one. /index (posts arbitrary
content as a global builtin) and /sync (re-indexes the shared library) now require a
platform admin key (X-Skills-Admin-Key, fixed-time compare, fail-closed when unset) via
SkillAdminOptions — previously any authenticated user of any org could inject/poison global
skills. New test asserts an authenticated Owner without the key gets 403 on both.
UI: new /skills library page — browse shared + org skills grouped by key with their versions,
create / new-version / fork, golden-test editor + body, Draft/Published badge and the
publish-gate hint (needs roles + ≥1 golden test).
Verified: ArchitectureTests 8/8, IntegrationTests 46/46 (new SkillLibraryTests: org
isolation, version coexistence, fork, publish gate, Member 403, admin-gate 403), client build
green.

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.
