# Plan Execute: Strategize & Execute Integration
## Overview
The plan executor connects the `PlanLifecycleService` to stub actors that
drive plans through the **Strategize** and **Execute** phases. In M1, these
actors are local-only stubs (no LLM calls); future milestones will integrate
real AI providers.
## Architecture
```
PlanExecutor
├── StrategizeStubActor (read-only, produces decision tree)
├── ExecuteStubActor (sandbox + ToolRunner + ChangeSet capture)
└── PlanLifecycleService (phase transitions, persistence)
```
## Phase Lifecycle
| Phase | Actor | Mode | Output |
|-------------|---------------------|-----------|---------------------------------|
| Strategize | StrategizeStubActor | Read-only | Decision tree, invariant records|
| Execute | ExecuteStubActor | Sandbox | ChangeSet, execution metadata |
## Strategize Phase
The strategize phase is **read-only**: it produces a decision tree from the
action's `definition_of_done` without modifying any resources.
### Decision Tree
The stub actor parses `definition_of_done` into discrete steps, each
represented as a `StrategyDecision` node with a ULID identifier:
```python
from cleveragents.application.services.plan_executor import (
PlanExecutor,
StrategizeResult,
)
executor = PlanExecutor(lifecycle_service=lifecycle, tool_runner=runner)
result: StrategizeResult = executor.run_strategize(plan_id)
# result.decision_root_id -> ULID of root node
# result.decisions -> list[StrategyDecision]
# result.invariant_records -> list[dict] (stub enforcement records)
```
### Invariant Propagation
Project and action invariants are propagated into the strategize context.
In M1, enforcement is stubbed (all invariants are accepted). Full
reconciliation via the Invariant Reconciliation Actor lands in D2.
## Execute Phase
The execute phase uses sandbox resources with tool calls routed through
`ToolRunner` and captured by `ChangeSetCapture`.
### ChangeSet Capture
All tool mutations during execute are recorded in a `ChangeSet`:
```python
result: ExecuteResult = executor.run_execute(plan_id)
# result.changeset_id -> ULID of the changeset
# result.changeset -> ChangeSet with entries
# result.tool_calls_count -> int
# result.sandbox_refs -> list[str]
```
### Metadata Persistence
After execute completes, the following metadata is persisted on the Plan:
- `changeset_id`: The ChangeSet identifier
- `sandbox_refs`: List of sandbox reference paths
- `error_details`: Tool call count and sandbox ref count
## Phase Guards
- **Execute requires Strategize COMPLETE**: The executor validates that the
plan has completed strategize (has a `decision_root_id`) before allowing
execute to proceed.
- **Phase validation**: Both `run_strategize()` and `run_execute()` verify
the plan is in the correct phase before proceeding.
## Error Handling
Failures in either phase are captured with full error context:
- `error_message`: The exception message string
- `error_details`: Dict containing `exception_type` and `traceback`
- The plan transitions to `ERRORED` processing state
### Retry Guidance
Plans in `ERRORED` state can be retried by:
1. Resetting the plan's processing state back to `QUEUED`
2. Re-running the failed phase via the executor
Full retry automation is planned for D1b (Phase Reversion & Error Recovery).
## Streaming Hooks
Both phases accept an optional `stream_callback` parameter for real-time
status updates (used by the `--stream` CLI flag):
```python
def my_callback(event_type: str, data: dict) -> None:
print(f"[{event_type}] {data}")
executor.run_strategize(plan_id, stream_callback=my_callback)
```
### Event Types
| Event | Phase | Description |
|------------------------|------------|---------------------------------|
| `strategize_started` | Strategize | Phase processing began |
| `strategize_decisions` | Strategize | Decisions produced |
| `strategize_complete` | Strategize | Phase completed successfully |
| `execute_started` | Execute | Phase processing began |
| `execute_step` | Execute | Individual decision being executed |
| `execute_complete` | Execute | Phase completed successfully |
## Module Reference
- **`cleveragents.application.services.plan_executor`**: Core module

Feature: Plan Actor Integration
As a developer
I want strategize and execute stub actors to drive plan phases
So that plans can be processed through the full lifecycle with ChangeSet capture
Background:
Given I have a plan executor service
# Strategize stub actor tests
Scenario: Strategize stub produces decisions from definition of done
Given I have a plan in strategize queued state with definition "Tests pass\nCoverage >= 90%"
When I run the strategize phase
Then strategize should produce 2 decisions
And the decision root id should be set on the plan
And the plan should be in strategize complete state
Scenario: Strategize stub handles single-line definition of done
Given I have a plan in strategize queued state with definition "All tests pass"
When I run the strategize phase
Then strategize should produce 1 decisions
And the decision root id should be set on the plan
Scenario: Strategize stub handles empty definition of done
Given I have a plan in strategize queued state with empty definition
When I run the strategize phase
Then strategize should produce 1 decisions
And the first decision should be "Complete the plan objectives"
Scenario: Strategize stub handles bullet list definition of done
Given I have a plan in strategize queued state with definition "- Unit tests pass\n- Integration tests pass\n- Coverage above threshold"
When I run the strategize phase
Then strategize should produce 3 decisions
Scenario: Strategize stub records invariant enforcement
Given I have a plan with invariants in strategize queued state
When I run the strategize phase
Then the strategize result should include invariant records
And each invariant record should have enforcement status
Scenario: Strategize is read-only and does not modify resources
Given I have a plan in strategize queued state with definition "Tests pass"
When I run the strategize phase
Then no changeset should be produced during strategize
And the plan sandbox refs should be empty
# Execute stub actor tests
Scenario: Execute stub captures tool calls through ChangeSet
Given I have a plan that completed strategize
When I run the execute phase
Then the changeset id should be set on the plan
And the plan should be in execute complete state
Scenario: Execute stub records execution metadata
Given I have a plan that completed strategize
When I run the execute phase
Then the plan should have execution metadata
And the tool calls count should be recorded
Scenario: Execute stub uses sandbox when provided
Given I have a plan executor with sandbox root
And I have a plan that completed strategize
When I run the execute phase
Then the plan sandbox refs should not be empty
# Phase transition guards
Scenario: Execute is prevented when plan is not in Strategize COMPLETE state
Given I have a plan in strategize queued state with definition "Tests pass"
When I try to run the execute phase
Then a plan error should be raised about phase mismatch
Scenario: Execute is prevented when plan has no decision tree
Given I have a plan in execute queued state without decisions
When I try to run the execute phase on the executor
Then a plan error should be raised about missing decisions
Scenario: Strategize fails when plan is not in strategize phase
Given I have a plan in execute phase for executor
When I try to run the strategize phase
Then a plan error should be raised about phase mismatch
# Error handling and status updates
Scenario: Strategize failure captures error details
Given I have a plan in strategize queued state with definition "Tests pass"
And the strategize actor is configured to fail
When I try to run the strategize phase expecting failure
Then the plan should be in errored state
And the plan should have error details
Scenario: Execute failure captures error details
Given I have a plan that completed strategize
And the execute actor is configured to fail
When I try to run the execute phase expecting failure
Then the plan should be in errored state
And the plan should have error details
# Streaming hooks
Scenario: Strategize emits streaming events
Given I have a plan in strategize queued state with definition "Tests pass"
And I have a stream callback registered
When I run the strategize phase with streaming
Then the stream callback should have received strategize events
And the stream events should include strategize_started
And the stream events should include strategize_complete
Scenario: Execute emits streaming events
Given I have a plan that completed strategize
And I have a stream callback registered
When I run the execute phase with streaming
Then the stream callback should have received execute events
And the stream events should include execute_started
And the stream events should include execute_complete
# Validation
Scenario: Strategize rejects empty plan id
When I try to run strategize with empty plan id
Then a validation error should be raised for empty plan id
Scenario: Execute rejects empty plan id
When I try to run execute with empty plan id
Then a validation error should be raised for empty plan id
Scenario: PlanExecutor rejects None lifecycle service
When I try to create a PlanExecutor with None lifecycle service
Then a validation error should be raised for None lifecycle service
# Strategy decision model
Scenario: StrategyDecision model validates fields
When I create a strategy decision with valid fields
Then the strategy decision should have the correct attributes
Scenario: StrategizeResult model stores decisions
When I create a strategize result with 3 decisions
Then the result should contain 3 decisions
And the result should have a root id
Scenario: ExecuteResult model stores changeset
When I create an execute result with changeset
Then the result should have a changeset id
And the result should have a changeset object
# Full lifecycle integration
Scenario: Full strategize then execute lifecycle
Given I have a plan in strategize queued state with definition "Write tests\nRun linter\nVerify coverage"
When I run the strategize phase
And I transition the plan to execute
And I run the execute phase
Then the plan should be in execute complete state
And the changeset id should be set on the plan
And the decision root id should be set on the plan

#### Phase 2 Notes (Preserved from Previous Work)
**2026-02-20**: D0b.execute — Plan Execute via Actors (M1 Critical Blocker)
- Created `src/cleveragents/application/services/plan_executor.py` with:
- `StrategizeStubActor`: Local-only stub that parses definition_of_done into decision tree
- `ExecuteStubActor`: Local-only stub with ToolRunner + ChangeSetCapture integration
- `PlanExecutor`: Orchestrator connecting PlanLifecycleService to stub actors
- `StrategyDecision`, `StrategizeResult`, `ExecuteResult` data models
- `StreamCallback` type alias for --stream CLI streaming hooks
- Strategize phase is read-only: produces decisions without modifying resources
- Execute phase uses sandbox resources and routes tool calls through ToolRunner
- Phase guards prevent Execute when Plan is not in Strategize COMPLETE state
- Error handling captures error_message + error_details with full traceback
- Invariant propagation stubbed (accepted without reconciliation until D2)
- Execution metadata (changeset_id, tool_calls_count, sandbox_refs) persisted to Plan
- Streaming hooks emit interim status updates (strategize_started/complete, execute_started/step/complete)
- Full test coverage: Behave features, Robot Framework integration, ASV benchmarks
- Documentation: docs/reference/plan_execute.md with architecture, lifecycle, and streaming API
**2025-11-22**: Week 12 Complete, Phase 2 Core Functionality DONE
- CLI Streaming Integration fully implemented
- AutoDebugGraph Implementation complete

"""Plan executor service: stub actors for Strategize and Execute phases.
Provides local-only (no LLM) stub actors for M1 that integrate with the
``PlanLifecycleService`` to drive plans through the Strategize and Execute
phases.
## Strategize Stub Actor
Accepts plan context and produces a minimal decision tree derived from
the action's ``definition_of_done``. The actor is **read-only**: it
records decisions in plan metadata without modifying any resources.
## Execute Stub Actor
Accepts plan context and the decisions produced by the strategize phase.
Routes tool calls through ``ToolRunner`` with ``ChangeSetCapture`` to
record all mutations. Persists ``changeset_id`` and execution metadata
(tool call count, sandbox refs) into plan metadata.
## Streaming Hooks
Both actors accept an optional *stream_callback* that is invoked with
interim status messages during processing. This enables the ``--stream``
CLI flag to emit real-time progress updates.
