Module attr 

Frozen attribute names. Every emitted field uses one of these constants.

These are a public contract — the OTLP exporter maps them straight onto span/event attributes, so renaming one invalidates existing dashboards. OpenTelemetry semantic conventions are used where one exists; everything else lives under the act.* namespace.

Constants

AGENT_ID

CAPABILITY_DECLARED

Whether the component declared this capability class in act.toml.

CAPABILITY_ID

COMPONENT_DIGEST

COMPONENT_REF

CONSENT_PROMPT_CHANNEL

Whether this run has any channel that can answer an interactive ask prompt at all (a real TTY, or an MCP client offering elicitation) — as opposed to headless / ACT-HTTP, where every ask decision degrades to deny before a human is ever involved. A per-run fact, repeated on every act.ceiling_class event so the layer never has to infer it from anything but typed fields.

CREDENTIAL_KIND

The kind string of a credential that was handed to a component — std:fields for everything this host writes, since a credential is a set of named fields and nothing else (design §3.2). Recorded because it is a required member of the published WIT secret record and a store may hold one written elsewhere. Non-secret by construction: it names a shape, never a value.

DECISION

DURATION_MS

NEVER_ROLLUP

Whether this decision must never fold into the per-call rollup, even when it resolves to Allow. Set for act:consent decisions — see CapDecisionRecord::never_rollup.

OUTCOME

POLICY_ACTOR

POLICY_MODE

POLICY_REASON

POLICY_RULE

REQUEST_ID

RESOURCE_ACTION

RESOURCE_KEY

SESSION_ID

TOOL_ARGS

Full tool-argument values, only present when --audit-args is set. TOOL_ARGS_SHA256 above is still emitted alongside it — this field widens the envelope, it never replaces the digest. Session args are never carried by either field: ToolCallStart has no such member.

TOOL_ARGS_SHA256

TOOL_NAME

TRACE_PARENT

TRACE_STATE

TRANSPORT
