Executive Summary + +1. **Warm Agents replaces the implicit loop-as-orchestrator pattern** in `SessionPrompt.loop()` with a deterministic dispatch system that validates intent before action and controls scope before mutation. +2. **The core abstraction is a WarmAgent**: a rehydratable execution context that carries scored warmness (loaded files, tool history, project familiarity) and can be matched to incoming tasks via capability routing. +3. **All agent and task state is externalized** to a durable store (extending the existing `Storage` layer), enabling process-restart recovery, CI/CD replay, and multi-agent handoff without conversational context loss. +4. **A typed lifecycle model** governs agents (`cold → warming → warm → executing → cooling → cold`) and tasks (`pending → claimed → executing → postchecked → completed | failed | rolled_back`), replacing the current implicit busy/idle/retry status. +5. **Deterministic routing rules** evaluate in a fixed priority order (pinned → warmest-qualified → cold-spawn), with every decision logged to an append-only audit trail. +6. **Safety interlocks** enforce blast-radius declarations, precondition gates, and postcondition checks before any mutation reaches the filesystem — extending the existing snapshot system with structured rollback. +7. **MCP lifecycle awareness** adds health checks, tool schema drift detection, and runtime routing fallback so warm agents degrade gracefully when MCP servers change or die. +8. **The migration is additive**: a new `warm/` directory under `packages/opencode/src/` introduces all subsystems as seams that the existing `SessionPrompt.loop()` can opt into incrementally. +9. **Three implementation phases**: prototype (single-agent warmness + task lifecycle), integration (multi-agent dispatch + safety harness), hardening (replay, drift handling, CI/CD mode). +10. **The quality bar is explicit provenance**: for any execution, a senior developer can answer what the agent was trying to do, what it was allowed to change, and what state survives process death — by reading the audit log and durable state alone. + +--- + +## 2.

Implementation Plan + +### Phase 1: Prototype (2-3 weeks) + +**Goal:** Single-agent warmness tracking + task lifecycle in isolation. + +| Step | Work | Files | +|------|------|-------| +| 1a | Create `packages/opencode/src/warm/` directory | New directory | +| 1b | Implement `WarmAgentState` + `TaskState` schemas | `warm/agent-state.ts`, `warm/task-state.ts` | +| 1c | Implement `StateStore` adapter (extends `Storage`) | `warm/state-store.ts` | +| 1d | Implement `WarmnessSorer` with four dimensions | `warm/scorer.ts` | +| 1e | Implement `AuditLog` (JSONL append-only writer) | `warm/audit.ts` | +| 1f | Add lifecycle state tracking to `SessionPrompt.loop()` | `session/prompt.ts` (additive seam) | +| 1g | Write unit tests for scorer, state machines, audit | `tests/warm/*.test.ts` | + +**Seam strategy:** In Phase 1, `SessionPrompt.loop()` gets an optional `WarmContext` parameter. If provided, it records state transitions and warmness updates. If not provided (default), behavior is identical to today. + +**Risk:** Warmness scoring heuristics may need tuning. +**Mitigation:** All weights are configurable constants, not hardcoded. Phase 1 includes logging to collect scoring data for calibration. + +### Phase 2: Integration (3-4 weeks) + +**Goal:** Multi-agent dispatch, invariant middleware, safety harness. + +| Step | Work | Files | +|------|------|-------| +| 2a | Implement `Scheduler` (dispatch loop + routing rules) | `warm/scheduler.ts` | +| 2b | Implement `CapabilityRegistry` (extends `Agent.state`) | `warm/capability-registry.ts` | +| 2c | Implement `InvariantMiddleware` (pre/post tool checks) | `warm/invariant.ts` | +| 2d | Implement `DispatchPolicy` rule evaluation | `warm/policy.ts` | +| 2e | Extend `Snapshot` with pre-task/post-task captures | `snapshot/index.ts` (minimal diff) | +| 2f | Implement rollback protocol | `warm/rollback.ts` | +| 2g | Implement `FailureReport` generation | `warm/failure-report.ts` | +| 2h | Wire Scheduler into `SessionPrompt.loop()` | `session/prompt.ts` (seam activation) | +| 2i | Wire InvariantMiddleware into `resolveTools()` | `session/prompt.ts` (wraps existing) | +| 2j | Add `--warm` CLI flag to opt-in | `cli/cmd/run.ts` | +| 2k | Integration tests: dispatch, rollback, failure reports | `tests/warm/*.test.ts` | + +**Seam strategy:** Phase 2 activates the Scheduler behind a `--warm` CLI flag. Without the flag, the existing `SessionPrompt.loop()` runs unchanged. With the flag, the Scheduler wraps the loop and manages dispatch. + +**Risk:** InvariantMiddleware adds latency to every tool call. +**Mitigation:** Invariant checks are synchronous schema matches (glob matching, set lookup) — sub-millisecond. No network calls in the hot path. + +### Phase 3: Hardening (2-3 weeks) + +**Goal:** MCP health, replay, `--auto` safety, production readiness. + +| Step | Work | Files | +|------|------|-------| +| 3a | Implement MCP health check timer | `warm/mcp-health.ts` | +| 3b | Implement tool schema drift detection | `warm/mcp-health.ts` | +| 3c | Implement runtime routing fallback | `warm/scheduler.ts` (extend) | +| 3d | Implement replay engine (audit log → re-execution) | `warm/replay.ts` | +| 3e | Implement `--auto` safety integration | `cli/cmd/run.ts` (extend) | +| 3f | Add structured failure reports to `--auto` output | `warm/failure-report.ts` | +| 3g | Process restart recovery scan | `warm/state-store.ts` (extend) | +| 3h | End-to-end tests: crash recovery, MCP drift, replay | `tests/warm/*.test.ts` | +| 3i | Documentation and config reference | `docs/warm-agents.md` | + +**Risk:** Replay fidelity — non-deterministic tool results (LLM, network) make exact replay impossible. +**Mitigation:** Replay engine validates *structural* equivalence (same tools called in same order) rather than output equality.
