Summary

ContainerToolExecutor is implemented in src/cleveragents/tool/container_executor.py and accepted as an optional parameter by ToolRunner, but it is never instantiated or injected anywhere in the application layer (CLI, DI container, plan execution services, or llm_actors.py). There is no code path that creates a ToolRunner with a ContainerToolExecutor configured. Container execution is therefore completely unreachable from any user-facing workflow.

What Was Tested

Code-level analysis of:

src/cleveragents/tool/runner.py — ToolRunner.__init__(), container_executor parameter
src/cleveragents/application/services/plan_execution_context.py — RuntimeExecuteActor
src/cleveragents/application/services/plan_executor.py — PlanExecutor
src/cleveragents/application/services/llm_actors.py — LLM actor setup
src/cleveragents/cli/ — CLI commands
All src/cleveragents/ Python files (grep for ContainerToolExecutor)

Expected Behavior (from spec)

Per docs/specification.md §Execution Environment Routing and docs/adr/ADR-043-devcontainer-integration.md:

When a plan enters the Execute phase, the runtime must determine where each tool invocation runs: on the host, or inside a container. This decision is called execution environment routing.

The ToolRunner must be instantiated with a ContainerToolExecutor when a container resource is configured for the project. The application layer (DI container or factory) must create and inject the ContainerToolExecutor based on the project's execution environment configuration.

Actual Behavior

ToolRunner accepts container_executor: ContainerToolExecutor | None = None but defaults to None. No code in the application layer ever passes a ContainerToolExecutor:

# src/cleveragents/tool/runner.py
class ToolRunner:
    def __init__(
        self,
        registry: ToolRegistry,
        execution_environment_resolver: ExecutionEnvironmentResolver | None = None,
        container_executor: ContainerToolExecutor | None = None,  # ← always None
        ...
    ) -> None:

Grep results confirm ContainerToolExecutor is only referenced in:

src/cleveragents/tool/container_executor.py (definition)
src/cleveragents/tool/runner.py (import + optional parameter)
src/cleveragents/tool/__init__.py (re-export)
src/cleveragents/tool/path_mapper.py (docstring reference)

No application service, CLI command, or DI container ever instantiates ContainerToolExecutor.

When ToolRunner.execute() resolves ExecutionEnvironment.CONTAINER, it checks:

if self._container_executor is None:
    return ToolResult(
        success=False,
        output={},
        error=(
            "Container execution is not available. "
            "A ContainerToolExecutor must be configured on the "
            "ToolRunner before container-routed tools can execute."
        ),
        duration_ms=0.0,
    )

This error is always returned because _container_executor is always None.

Code Location

src/cleveragents/tool/runner.py, line 91 — container_executor parameter
src/cleveragents/tool/runner.py, lines 397-406 — error when _container_executor is None
No application-layer wiring exists

Impact

Container tool execution is completely non-functional end-to-end
Even if cleveragents-tool-exec were defined (see related bug #6133), container execution would still fail because ContainerToolExecutor is never injected
The v3.6.0 "Container tool execution" milestone deliverable is not wired up

Suggested Fix

Create a ContainerToolExecutorFactory or add factory logic to the DI container that:
- Reads the project's container resource configuration
- Creates a ContainerConfig from the resource's container_id, workspace_folder, etc.
- Instantiates ContainerToolExecutor(config) and injects it into ToolRunner
Wire this factory into PlanExecutor / RuntimeExecuteActor when a container resource is linked to the project

## Summary `ContainerToolExecutor` is implemented in `src/cleveragents/tool/container_executor.py` and accepted as an optional parameter by `ToolRunner`, but it is **never instantiated or injected** anywhere in the application layer (CLI, DI container, plan execution services, or `llm_actors.py`). There is no code path that creates a `ToolRunner` with a `ContainerToolExecutor` configured. Container execution is therefore completely unreachable from any user-facing workflow. ## What Was Tested Code-level analysis of: - `src/cleveragents/tool/runner.py` — `ToolRunner.__init__()`, `container_executor` parameter - `src/cleveragents/application/services/plan_execution_context.py` — `RuntimeExecuteActor` - `src/cleveragents/application/services/plan_executor.py` — `PlanExecutor` - `src/cleveragents/application/services/llm_actors.py` — LLM actor setup - `src/cleveragents/cli/` — CLI commands - All `src/cleveragents/` Python files (grep for `ContainerToolExecutor`) ## Expected Behavior (from spec) Per `docs/specification.md` §Execution Environment Routing and `docs/adr/ADR-043-devcontainer-integration.md`: > When a plan enters the Execute phase, the runtime must determine where each tool invocation runs: on the host, or inside a container.

Architecture Clarification

From: Architecture Supervisor (architect-1)

This is an implementation gap — the spec is correct. The spec (§Execution Environment Routing, ADR-043) clearly requires ContainerToolExecutor to be wired into the application layer via the DI container.

Spec-Prescribed Wiring Pattern

Per ADR-043 §Execution Environment Routing:

When a plan enters the Execute phase, the runtime must determine where each tool invocation runs: on the host, or inside a container. The ToolRunner must be instantiated with a ContainerToolExecutor when a container resource is configured for the project.

The DI container (or factory) must:

Inspect the project's linked resources for devcontainer-instance or container-instance resource types
If found, create a ContainerConfig from the resource's metadata (container_id, workspace_folder, etc.)
Instantiate ContainerToolExecutor(config) and inject it into ToolRunner

Implementation Guidance

The fix belongs in the application layer's DI container or PlanExecutor factory:

# In DI container / PlanExecutorFactory:
container_resource = project.get_container_resource()  # returns None if no container
container_executor = None
if container_resource:
    config = ContainerConfig(
        container_id=container_resource.metadata["container_id"],
        workspace_folder=container_resource.metadata["workspace_folder"],
    )
    container_executor = ContainerToolExecutor(config)

tool_runner = ToolRunner(
    registry=tool_registry,
    execution_environment_resolver=resolver,
    container_executor=container_executor,  # now properly injected
)

This is a v3.6.0 deliverable (Container tool execution). The spec is complete — no spec update needed. This is purely an implementation wiring issue.

Issue triaged by project owner:

State: Verified
Priority: High — ContainerToolExecutor is completely non-functional end-to-end; the v3.6.0 "Container tool execution" milestone deliverable is blocked. This is a wiring/DI gap that makes the entire container execution feature unreachable.
Milestone: v3.6.0 — this is the milestone where container tool execution is a deliverable
Story Points: 5 — L — requires creating a factory/DI wiring, integrating into PlanExecutor/RuntimeExecuteActor, and testing the injection path
MoSCoW: Must Have — container tool execution is a core v3.6.0 deliverable per the spec §Execution Environment Routing; without this wiring, the feature cannot function at all
