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.

SharedKernel:
- ActionRisk (risk lives on the action) + GatePolicy (the pure autonomy x risk matrix:
Read never holds, Draft/Publish hold unless Autonomous, Destructive ALWAYS holds).
- IActionGate (AgentActionProposal -> execute|hold) and IBoardWriter.AttachArtifactAsync.
Governance:
- ReviewItem (held action: artifact, child titles, trace, decision, edit distance) in a new
review_items table (AddReviewItems migration).
- ActionGate: hold -> ReviewItem + "action.held" audit; autonomous -> execute + audit.
- HeldActionExecutor: writes the artifact onto the task and creates the child tasks via
IBoardWriter (implemented by OrgBoard — no cross-module table access).
- Review inbox API: GET /api/governance/reviews (scope-filtered to where the caller may
approve), POST /reviews/{id}/approve (optional edited content/children -> normalized
edit distance recorded — the north-star metric), POST /reviews/{id}/sendback. Deciding
twice is 409; Members are 403.
Assembler:
- OutputParser (numbered-list child titles, conservative) and the executor now hands every
completed run's proposal to the gate.
OrgBoard: WorkItem.AttachArtifact + BoardWriter.AttachArtifactAsync.
Verified: build green; ArchitectureTests 8/8; IntegrationTests 41/41 incl. the full M5
acceptance — Aria (gated) proposes a spec, it waits in the inbox with its trace, a Member is
403'd, the owner edits-and-approves, the spec + four child stories land on the board, edit
distance > 0 is recorded and audited; Quill (autonomous) executes straight to the board;
destructive holds even for an autonomous seat and can be sent back. Plus the GatePolicy matrix.
