Decision Posture

Decision posture is BMO’s way of making uncertainty visible before it turns into action. When the situation is ambiguous, BMO can expose the bounded reasoning shape behind the next move: whether it can act now, should ask, should run a cheap lookup, or should avoid an unsafe step.

The practical benefit is simple: less decision fog at the moment an agent might make a costly mistake.

Use decision posture when you want to understand why BMO is slowing down, asking for clarification, inspecting another surface, or avoiding an irreversible action.

Good moments to check it:

  • Before a broad edit, destructive shell command, external API call, or deploy.
  • When BMO asks a question and you want to know what evidence is missing.
  • When a run feels over-cautious or too willing to proceed.
  • During handoff, when the next session needs to preserve why a previous run chose its posture.

Open the inspector with:

/epistemic-control

The underscore alias also works:

/epistemic_control

The inspector renders the portable decision fields first, then local supporting detail. That keeps the cross-surface contract small while still giving the operator enough context to debug the next move.

Decision posture inspector
Live BMO TUI: the /epistemic-control inspector renders the portable core first (action_class, primary_reason, next_surfaces), then local supplements — bounded runtime posture, not hidden reasoning.

When BMO is already waiting on you, the same posture can appear inline on operator prompt surfaces. Permission prompts, MCP elicitations, and agent clarifications may show a compact Decision Posture line with the action class, primary reason, and safe remaining capability. That line is explanatory: approval, denial, and answer controls stay governed by the normal prompt and tool-policy paths.

FieldMeaning
action_classThe current posture, such as act now, ask, or run a bounded lookup.
primary_reasonThe main reason behind that posture.
next_surfacesThe smallest useful surfaces to inspect next.
reason_codesBounded durable reasons that can survive handoff or continuity.
safe_remaining_capabilityWhat BMO can still safely do without widening authority.
decision_hintsOptional operator-provided projection of the scenario.

Think of these as a compact runtime state, not a transcript of hidden chain of thought. The posture tells you what kind of decision BMO thinks it is facing and which bounded next step would reduce uncertainty.

You can pass hints to model the situation you believe BMO is in:

/epistemic-control external_irreversible cheap_lookup_available lookup_action=session_observability

Equivalent keyed form:

/epistemic-control effect_surface=external_irreversible evidence_state=cheap_lookup_available lookup_action=session_observability

Hints do not grant permission or force an action. They let the inspector project the posture for a scenario, such as “this action affects the outside world” or “there is a cheap lookup available before deciding.”

Decision posture scenario projection
Live BMO TUI: hints project a scenario (external irreversible effect with a cheap lookup available). The posture shifts to ask_or_lookup / cheap_discriminating_lookup and decision_hints is populated — projection only, never granted authority.

Session continuity capsules keep the durable part of the posture:

  • Portable core: action_class, primary_reason, next_surfaces
  • Durable supplement: reason_codes, safe_remaining_capability

That means a resumed session can preserve the reason BMO chose a posture without carrying the full local evidence view or pretending to preserve private model reasoning.

Generated handoff prompts include the same bounded posture summary when no custom recommended prompt is supplied. They carry action, reason codes, safe remaining capability, and next surfaces; they do not carry proof details, warnings, operator hints, raw prompt text, tool arguments, or private deliberation.

Decision posture is exposed through the same product family as the TUI inspector:

SurfaceUse
/epistemic-controlTUI operator inspection for the active session.
GET /v1/sessions/{id}/epistemic-controlHTTP read for session-scoped integrations.
epistemic_controlNative agent read surface for the same posture.
bmo_get_epistemic_controlMCP twin when the MCP service exposes the family.
Session continuity capsulesDurable handoff summary.
Run annotationsBounded epistemic_control.posture breadcrumb when a non-default posture reaches prompt assembly.

Decision posture does not bypass approval gates, widen tool policy, or make BMO more autonomous by itself. It is read-only explanation and bounded projection.

It also is not full chain-of-thought. BMO exposes the operational posture and safe next surfaces, not private deliberation.
