Reusable agent definitions authored as AGENTS.md (YAML frontmatter + a Markdown body that becomes
the agent's operating guide). Mirrors the skill library, including its review hardening.
- AgentProfile entity (OrgBoard): org-scoped + versioned by (OrganizationId, ProfileKey, Version),
NULLS NOT DISTINCT unique index; Origin Builtin|Authored|Installed; ProfileVisibility +
ProfileStatus with the Public⟹Published invariant enforced in Apply()/SetVisibility(). AGENTS.md
parser (YamlDotNet). AgentProfileWriter is the single upsert path (insert-only mode for install).
- Free builtins: AgentProfileSeeder seeds Aria (PO), Quill (QA), Edison (backend) on startup via a
new IStartupSeeder + SeederRunner (runs after migrations). Idempotent, null-org, visible to all.
- Endpoints (/api/orgboard/agent-profiles): upload, list (resolvable-winner order), get versions,
publish/unpublish, fork, marketplace (per-(key,version) AlreadyInLibrary), install (insert-only →
clean 409, no clobber). ConfigureAgents to author/manage; ViewBoard to browse; audited.
- Persona: Agent gains Persona; ConfigureAgent stores it; AgentRunContext carries it; PromptAssembler
injects it as "# Operating guide" (data, not instructions) so an applied profile shapes the run.
- Client: Agent profiles page (library + marketplace tabs, upload editor, publish/unlist/fork/install),
routed + in the nav.
Verified: ArchitectureTests 8/8, IntegrationTests 55/55 (new AgentProfilesTests: builtins seeded,
upload + validation, publish, cross-org marketplace list→install→private copy, duplicate 409, per-
version flag, Member 403; persona renders as the operating guide), client build green.
