Section titled “ Responses ”Paginated list of capabilities
Response wrapper for paginated list endpoints. Includes pagination metadata along with the data array.
next_url and prev_url are populated by the [decorate_pagination_links]
middleware after the handler returns, so handlers don’t need to thread the
request URL into every construction site.
object
Array of items returned by the list operation.
Wrapper that adds API and UI links to a serialized resource.
Uses self_url (not url) for the API link to avoid collision with
resources that already have a url field (e.g. McpServer). The
allowed_actions array carries state-aware hypermedia links — empty
(and omitted from the wire shape) until the underlying resource opts
into the convention by overriding ResourceUrlable::allowed_actions.
object
Number of active agents referencing this capability in the org.
Category for grouping in UI
JSON Schema for capability-specific per-agent config.
object
React-jsonschema-form uiSchema hints for rendering config_schema.
object
IDs of capabilities that this capability depends on. When this capability is selected, its dependencies are automatically included.
Description of what this capability provides
Slug under https://dev.everruns.com/capabilities/ when public docs exist.
UI feature strings this capability contributes to. Multiple capabilities can contribute the same feature.
Number of active harnesses referencing this capability in the org.
Icon name (for UI rendering)
Unique capability identifier
Whether this capability is a guardrail (constrains agent behavior rather than granting abilities). Used for UI grouping and filtering.
Whether this is an MCP server capability (for UI badge)
Whether this is an Agent Skill capability (for UI badge)
Localized display strings keyed by lowercase language tag (e.g. “uk”).
The “en” entry carries only config_description, since the base
name/description/config_schema strings are already English.
object
Localized display strings for one locale of a capability.
object
One-line summary of what this capability’s config controls.
Overlay merged into config_schema before rendering: mirrors the
schema property tree with title/description/enum_labels leaves.
object
Localized description; absent means fall back to description.
Localized display name; absent means fall back to name.
Display name
TM-AGENT-005: Risk level. High-risk capabilities require admin approval.

object
State-aware hypermedia actions the caller can take on this resource
next (e.g. cancel, events, update). Omitted from the wire
shape when empty so resources that haven’t opted into the
convention don’t grow their payloads.
Agent-actionable link describing a follow-up the caller can take. Used in two contexts:
- Error recovery —
ErrorResponse.allowed_actionscarriesrels likeretry,retry-later,unarchive,get-existingso the agent knows the right next call after a 4xx/429. - Entity hypermedia —
WithUrls<T>.allowed_actionscarries state-awarerels likecancel,events,self,updateon the entity itself so the agent can follow links instead of reconstructing routes from prose.
The shape is intentionally identical across both contexts; the closed
rel vocabulary documented in specs/api-conventions.md distinguishes
them.
object
Short, agent-readable hint (e.g. “Shorten ‘name’ to <= 200 chars.”, “Cancel the active turn for this session.”).
Absolute (preferred) or relative URL the caller may invoke
directly. Always present on entity hypermedia actions
(WithUrls<T>.allowed_actions); optional on error-recovery
actions (ErrorResponse.allowed_actions) where the matching
operation_id is enough and the URI is implicit from the failed
call.
HTTP method to use against href. Required for entity hypermedia
actions; usually omitted on error-recovery actions where the same
operation is retried with its original method.
OpenAPI operationId the caller should invoke. Lets an MCP client
resolve the call without parsing href.
Link relation describing the action. Closed vocabulary documented
in specs/api-conventions.md — examples: self, cancel, pause,
resume, events, retry, retry-later, unarchive,
get-existing, delete, update.
OpenAPI $ref to the request-body schema, when the action takes one
(e.g. #/components/schemas/UpdateSessionRequest). Lets a tool-calling
agent fetch the input shape without scanning the whole spec.
Full API endpoint URL for this resource.
Alias for view_url, used by command and MCP outputs.
Full UI URL for viewing this resource.
Maximum number of items per page.
Absolute URL for the next page, with offset advanced by limit. Omitted from the response (field absent) when this is the last page.
Current offset (starting position).
Absolute URL for the previous page, with offset rolled back by limit. Omitted from the response (field absent) when this is the first page.
Total number of items matching the query (across all pages).

Standard error response.

detail, code, allowed_actions, retry_after_seconds, instance,
