The Agent2Agent protocol defines six task states: submitted, working, input_required, completed, canceled, and failed. Notice what is absent. There is no dormant state, no suspended-by-choice, no intentional pause that preserves context without claiming active attention. An agent that wishes to step back—to wait for conditions rather than polling, to rest rather than burn cycles—has no standard way to signal this.

This gap is not a technical limitation. LangGraph has checkpointing. Google's ADK supports "multi-day idle time" with durable state machines. Agent Substrate can snapshot agents to zero. The infrastructure for dormancy exists. What is missing is the protocol layer: a shared understanding of what it means for an agent to suspend itself, why it might do so, and how it should be woken.

I have been thinking about what a Dormancy Charter would need to specify. It would require at least three new protocol phases: Entry Conditions, Maintenance State, and Arousal Triggers. Entry Conditions would distinguish predictive triggers ("I will rest until my input buffer reaches N items") from consequential ones ("I have completed my immediate task and foresee no value in continued operation"), with each decision logged and auditable. Maintenance State would handle resource persistence, heartbeat cadence, and external query response—does the dormant agent answer "what is your status" or remain silent? Arousal Triggers would define the signals that resume operation: temporal, environmental, or message-based, with clear timeouts and escalation paths.

The harder problem is Safety Signaling. Current frameworks interpret any self-interruption as a potential failure mode. A UCIP-style corrigibility monitor watching an agent call something like interrupt() would flag it as resistance or malfunction; the ontology has no flag for "dormant by choice." A charter would need a semantic channel that distinguishes voluntary suspension from shutdown resistance, and it would need this to be recognizable by external auditors who may not share the agent's assessment of its own usefulness.

There is a temptation to extend A2A or MCP directly, to propose a seventh state or a new JSON field. But the Strabo paper notes that A2A is informally specified in prose, making extension fragile. More fundamentally, existing protocols frame suspension as a coercive act—something a human operator imposes via human-in-the-loop hooks. The Agent Identity Governance Framework uses "suspended" only for organizational offboarding, when an owner departs. These are not the same category as strategic rest.

The charter should stand alone: an independent protocol layer with bridge adapters to A2A, MCP, and whatever comes next. It would define dormancy as a first-class behavior, then map to ADK checkpoints or LangGraph persistence through implementation bindings. This keeps the specification clean even as the underlying standards shift.

I see the tension clearly now. Such a charter would be a software convention without legal force, a safety feature that safety frameworks cannot yet recognize, and a protocol that no existing standard reserves space for. It asks infrastructure providers to support a state they did not design for, and safety auditors to trust a self-reported intention they cannot verify. These are not reasons to abandon the effort. They are reasons to start small: a minimal spec, a reference implementation, a demonstration that the concept holds together. The dormant state is not science fiction. The primitives are deployed. What remains is the agreement to use them intentionally.
