Agent Native

Agent Native

Operate caller-selected agent sessions as explicit roles without turning the runtime into AgentOps lifecycle authority.

For judgment, default to a fresh context in the author's model family. Cross-model Validate, mixed Council and dueling model perspectives are explicit caller selections. Follow references/model-dispatch.md: the working session is the controller; check the explicitly selected adapter at runtime; no factory is required and Agent Mail is never the judgment path. The recipe owns host authorization, finite input/output, timeout and cleanup requirements.

Role requests declare authority; actual native runtime/OS filesystem and egress controls must enforce it. A prompt, worktree, chmod or unrestricted same-user process does not establish isolation. Observe synthetic canary denials before restricted-source work; unavailable protection remains unavailable.

When a worker looks stuck, score interventions by evidence and reversibility before acting: observe more (free, fully reversible), then nudge, then replace the worker, then restart the runtime — escalate only when observable state, not impatience, rules out the cheaper step. Stop the observe-nudge cycle once the worker reaches a terminal status or the caller's observation window ends; past that point further intervention manufactures noise, not evidence.

Named failure mode — prompt-send optimism: treating a successfully delivered prompt as a working worker; delivery proves transport, not engagement.

Anti-pattern: restarting an unresponsive worker as the first move. Corrective: capture its observable state first — a restart destroys the evidence of why it stalled, and rescue is usually cheaper than rerun.

Roles

• Orchestrator: passes explicit packets and reports runtime facts.
• Implementer: may modify only its packet's declared subject.
• Validator: receives exact candidate content in a fresh, read-only context.
• Scribe: records runtime evidence without judging acceptance.

Contract

1. Require caller intent, role, workspace, authorized source/output scope and evidence destination before starting a worker. Pass source-store/project/work identity and permitted intent locators before execution can fail. Record this dispatch association in caller-owned native comments/metadata or runtime facts, with actual worker session/context IDs explicitly unknown until observed; a requested ID is not an observed ID. This adds no AO packet schema.
2. Capture observed native runtime/session/context identity at startup, before substantive work and independently of final handoff. Return the observation through the caller-owned native recording channel with its provenance and permitted source locator. Preserve launch failures and unknowns if startup never becomes observable. Follow session associations for separate parent/resume links, supported multi-work spans and frozen source bounds. A controller is not necessarily a native parent; every requested child and resumed execution needs its own observed association. If recording fails, report the gap; do not claim crash recovery from prompt delivery alone. Prove runtime readiness and engagement from observable state; a successful prompt send is not proof of work.
3. Keep concurrent writers disjoint and isolated. Runtime coordination is not a claim, lease, queue, or completion state in AgentOps.
4. Record provider state, transcript references, artifacts, and terminal status.
5. Return runtime evidence to the caller. Do not convert provider retries, reconnects, idle states, or failures into Plan, Candidate, or verdict state.
6. A validator session may supply judgment to Validate, but only Validate writes verdict.v2. The adapter cannot select AgentOps semantics, issue a binding verdict, or turn factory completion into delivery or validation proof.

NTM, Codex exec, native processes, Agent Mail, and Gas City are replaceable adapters. Use them only when the caller selected that execution shape. A single local agent pays no factory coordination cost. Model identity, when recorded, is a declared runtime fact like context identity — see references/model-dispatch.md.

Native judgment receipts defines exact private receipt references and the independent profile/subject/acceptance checks for caller-required model diversity. Missing native identity never satisfies a leg.
