+### Product Agent resource configuration
+
+The V1 product definition lives in the [Agent configuration product document](https://vrfi1sk8a0.feishu.cn/wiki/TEhDwRlRpiGIcRkbKywcfEydn7g).
+The Build inventory is Models, Environments, Capabilities, Integrations and
+Credentials. Agent creation/editing selects those resources plus Harness. Product
+resource selection and credential binding belong to Parsar; public protocol
+features not yet implemented by Core remain explicit reservations, not alternate
+product execution paths or changes to Core's contract.
+
+- `resource_bindings` on Agent create/update contains version, pinning mode and
+  per-resource configuration. Agent changes and the complete binding selection
+  commit atomically. Omitting the field preserves bindings; an empty array clears
+  them. Updating credentials preserves the selected version and pinning mode.
+  Retaining an existing binding does not reapply new-install eligibility after
+  unpublishing or deprecation; changing its version or tracking mode does. Retained
+  foreign private resources never expose later private revisions.
+- Capability bindings reuse `agent_capabilities` and Build imports. Model
+  credentials default to the Provider key; an explicit
+  `config.model_credential_binding` chooses a credential `kind` and personal/shared
+  source. Model bindings accept only `openai_api_key` and `anthropic_api_key`;
+  unrelated personal secrets must never become Provider tokens. Migrations register
+  these model credential kinds without requiring development fixtures. Personal means
+  the run requester, never the creator of a
+  shared Agent. Public Agents require shared credentials. Existing per-capability
+  choices take precedence over Agent-wide defaults. Missing references remain
+  visible and require repair; lookup failures never substitute another credential.
+- Inline resource creation keeps the Agent draft. Workspace communication
+  connectors (Feishu, Slack, Discord and Teams) retain their shared scope and
+  existing management APIs, with immediate-save scope stated in the Agent form.
+  Dedicated Agent Feishu configuration remains owned by its existing API and is
+  preserved when execution configuration is replaced.
+- Skills verify the original owned archive and checksum, then adapt Build rootless
+  ZIP layout and descriptive slug/title metadata to public inline Skill initialization.
+  Supporting bytes and executable modes are preserved; native activation controls
+  remain unsupported. System prompts and knowledge
+  become protocol instructions. Core currently cannot combine a referenced
+  Environment Template with additional Skills, or hosted execution with MCP;
+  Plugins also remain unsupported. Preserve the Template selector and show these
+  gaps. Do not silently drop a binding to start a partially configured Agent.
+- Freeze Skill bytes and selected model credentials in the existing encrypted
+  private Session snapshot, separate from the ordinary request. Restore the
+  existing snapshot before reading mutable resources; decrypt initialization only
+  for the Core request. Editing resources or credentials affects new Sessions.
