Skill discovery, authoring, and policy — agent access

Product map: Skill discovery, authoring, and policy.

Feature ID: skills.

Review date: 2026-10-12. Source commit: 58e16dbddfc9c8d0cf60867f9d9847f0feda055b. Native REST transport reconciled in this change; see the shared transport contract.

This is a source-reviewed baseline of representative operations and known gaps. Each capability needs operation-level review before its entire scope can be qualified. No live agent execution is claimed. Follow the map contract for format, permission checks, evidence and maintenance.

Cold Git package recovery rechecks the original source's current setup identity, company membership, policy and repository grant. It never borrows another company's credentials or substitutes a moving branch for the saved commit. A missing/revoked source fails with a reconnect error and persisted retry backoff. Warm access still uses the ordinary skill/project permission check.

External package storage changes persistence, not agent authority. Runtime selection still checks current company/project access before consulting immutable package caches; no storage key is exposed as an agent capability. Public selected rows are constrained to access_source_id IS NULL at their final read. Warm package and native asset caches hold file metadata, never authorization decisions. The concurrency regression covers separate actors and revoked project access; the package regression covers company isolation and warm-cache behavior. This does not claim live agent qualification.

Managed ownership remains in the existing workspace policy category. Immutable content references do not grant authority: publication rechecks policy and source access, and delivery/recovery rechecks the company's skill visibility. File reads and mutations return versionId; content requests may supply expectedVersionId and receive 409 on a stale base. Existing idempotent agent receipt shapes remain. Detached assignments do not release active/recovering execution pins. These are source-reviewed contracts; the independent-process board fixture is not agent credential or hosted Runner qualification.

discovery

Capability ID: skills/discovery.

Review: baseline.

API: present — representative operation IDs:

• GET /api/companies/{companyId}/skills.
• POST /api/companies/{companyId}/skills/import.

Agent access: available — REST / native call_api / CLI skills and sources. Queue and HTTP/2 sandbox callbacks also admit company skill detail and file reads; file paths travel in the existing path query parameter. Skill mutations stay subject to the existing bridge restrictions.

Policy: Company skill policy by action/resource plus platform invariants; test execution additionally requires task-assignment authority.

Evidence: source-only — implementation at the reviewed commit above.

Verification: not-run — exercise a listed permitted operation with actual agent credentials/run context; inspect its result and applicable persistence/attribution. Assert the relevant denied actor, owner, company or mode from Policy. Review the remaining operations before qualifying the whole capability.

Gaps: Installation/import is governed by company skill policy, not inferred from an agent's role name.

authoring

Capability ID: skills/authoring.

Review: baseline.

API: present — representative operation IDs:

• POST /api/companies/{companyId}/skills.
• PATCH /api/companies/{companyId}/skills/{skillId}/files.

Agent access: available — Native create_skill/update_skill for single-file operations; REST for other files/metadata.

Policy: Company skill policy by action/resource plus platform invariants; test execution additionally requires task-assignment authority.

Evidence: source-only — implementation at the reviewed commit above.

Verification: not-run — exercise a listed permitted operation with actual agent credentials/run context; inspect its result and applicable persistence/attribution. Assert the relevant denied actor, owner, company or mode from Policy. Review the remaining operations before qualifying the whole capability.

Gaps: Writable/fork policy and expected version apply. Native helpers intentionally support a narrower shape than full API.

versions

Version lists and current/test-run version summaries contain file names and kinds. Use GET /api/companies/{companyId}/skills/{skillId}/versions/{versionId} for the selected version's file contents. Authorization remains company/skill scoped; support inspection reads only stored bytes for the requested version and does not recover Git.

Capability ID: skills/versions.

Review: baseline.

API: present — representative operation IDs:

• GET /api/companies/{companyId}/skills/{skillId}/versions.

Agent access: available — REST / native call_api / CLI skills.

Policy: Company skill policy by action/resource plus platform invariants; test execution additionally requires task-assignment authority.

Evidence: source-only — implementation at the reviewed commit above.

Verification: not-run — exercise a listed permitted operation with actual agent credentials/run context; inspect its result and applicable persistence/attribution. Assert the relevant denied actor, owner, company or mode from Policy. Review the remaining operations before qualifying the whole capability.

Gaps: Revision metadata has an API; pinned execution skill versions and installed latest are distinct.

Runtime disk-cache expiration does not delete version records or change access. Normal execution rematerializes saved bytes after existing skill authorization; cleanup is an internal company-scoped maintenance operation, with no new agent endpoint. Verify pinned restoration and active-run protection with server/src/__tests__/skill-version-cache.test.ts and the assembled heartbeat runtime-skill tests; live acceptance remains separate.

Native runs with an empty effective or saved selection do not read skill files or wait for the company cache lock. Explicit references still require the existing skill authorization. Selected skills and legacy operational skills retain cache exclusion and immutable version pinning. This changes no agent endpoint or grant; the configuration tests cover the held-lock boundary with real PostgreSQL.

Concurrent preparations share only in-flight inventory reconciliation. After that work, each actor's visible skill rows are read again under the company cache lock. Snapshot delivery and durable run pins complete before the lock is released. No permission result is shared or kept between requests. The concurrency tests cover separate actors and project-access revocation; this adds no agent API.

policy

Capability ID: skills/policy.

Review: baseline.

API: present — representative operation IDs:

• PUT /api/companies/{companyId}/skill-policy.
• POST /api/agents/{id}/skills/sync.

Agent access: partial — REST / native call_api under users:manage_permissions or target configuration policy.

Policy: Company skill policy by action/resource plus platform invariants; test execution additionally requires task-assignment authority.

Evidence: source-only — implementation at the reviewed commit above.

Verification: not-run — exercise a listed permitted operation with actual agent credentials/run context; inspect its result and applicable persistence/attribution. Assert the relevant denied actor, owner, company or mode from Policy. Review the remaining operations before qualifying the whole capability.

Gaps: Policy administration has an explicit agent grant branch; assigning agent skills also checks the target's config authority.

The configuration-gated GET /api/agents/{id}/skills reads repository cache locations without materializing versions or validating their support files. Assignment mutations and run preparation retain their existing authorization. The database-backed cache tests cover latest/pinned reads and full validation during execution; they do not prove live agent access. Both skill-list and skill-sync responses preserve stored version pins rather than returning a resolved runtime version as a pin. Latest remains unpinned across an assignment round trip.

testing

Capability ID: skills/testing.

Review: baseline.

API: present — representative operation IDs:

• POST /api/companies/{companyId}/skills/{skillId}/test-runs.

Agent access: available — Permitted agent REST / native call_api creation, control and history; no dedicated CLI test command found.

Policy: Company skill policy by action/resource plus platform invariants; test execution additionally requires task-assignment authority.

Evidence: source-only — implementation at the reviewed commit above.

Verification: not-run — exercise a listed permitted operation with actual agent credentials/run context; inspect its result and applicable persistence/attribution. Assert the relevant denied actor, owner, company or mode from Policy. Review the remaining operations before qualifying the whole capability.

Gaps: No dedicated native orchestration binding; generic REST calls retain skills.test policy, task-assignment authorization, responsible-user intersection and admitted skill-test JWT scope.

Studio's skill_test work mode is admitted through native Runner selection and preserved in execution input. The admitted task-bound scope restricts REST and native authorization, including after task-mode edits and recovery. Native tools allow only the harness task and admitted skills. Task creation, company browsing, connectors and assigned MCP tools are unavailable; native mutation receipts recheck the scope before replay or effects. Preparation reads the pinned version from the durable test row, replaces ordinary assignments, and enforces current skill access. Required environment skills retain their owner policy; a shadowed test pin fails explicitly. Recovery preserves the admitted selection. Preconfigured Runner homes reject managed Studio delivery. The execution configuration regression covers unassigned historical pins, Beta skills disabled, revoked access, recovery, unchanged agent assignments, and assembled heartbeat dispatch.

Project-source API additions: GET /api/companies/{companyId}/skill-sources/project-repositories, POST /api/companies/{companyId}/skill-sources/adopt-project with workspaceId, and PATCH /api/companies/{companyId}/skill-sources/{sourceId}/settings with expected revision and update/connection preferences. trackingRef accepts a branch or explicit ref; "HEAD" keeps default-branch tracking. GET /api/companies/{companyId}/skill-sources/{sourceId}/branches returns a bounded branch list and the default branch, with optional connectionId for connection repair. It requires source access and skills.edit, and reads only through the caller's authorized GitHub grant. Saving validates the requested ref before changing an independent source; active project bindings must be edited through their project configuration. Responses identify branch, connection, or retry repair and distinguish queued imports from imports under an active worker lease. Native API discovery uses the OpenAPI registration.

Project-derived read/use permission follows current project authorization, with access through either originating project. File/version reads, source metadata, mutations, editable copies, tests and runtime delivery retain that boundary. Unattended refresh uses the revalidated setup identity and connection, not the requesting agent's token. These additions need actual permitted/denied agent-run acceptance; service tests alone are not live credential proof.

Direct GitHub source imports share the project setup-identity boundary. API-key agents may import permitted public content, but their responsible-user field does not authorize unattended credential use. They need human connection repair for automatic refresh. Authenticated agent runs derive the setup person from the persisted active run. Legacy agent activity without a matching run cannot recover a refresh person. Route and database tests cover these distinctions; this addition makes no new live-provider acceptance claim.

Initial project imports check skills.import before provider reads; denied jobs do not retry automatically. Deferred jobs remain durable behind per-project and company admission limits. Scheduled refresh compares immutable tree identity and uses a persistent work allowance; manual refresh still requires its existing policy/access checks. These limits grant no content or execution access.

Repository import, preview, and refresh share the bounded dependency-package fallback. Missing-reference warnings do not deny an otherwise authorized import. Recovered files come only from the same immutable, authorized Git tree and pass the existing content audit; no host paths or additional credentials are consulted. Source tests cover transitive files, limits, retained versions, and legacy dependency-error recovery.

Agent repository setup preserves the active run's selected GitHub connection/grant IDs. Missing selections require human repair; the worker never searches the responsible person's other grants for an agent-created source.

Initial automatic imports reserve company work credits before provider reads. Failures retain the reservation; completed jobs cannot replenish the queue's work allowance. Jobs remain durable and resume as company credits refill.

Plugin runtime synchronization uses the agent's current skill access and immutable version resolver. A change to an installed skill invalidates its referencing agents. Private-source access changes also request reconciliation. This is a host-to-plugin hook, not a new agent-facing endpoint. See contract and database coverage.
