# Review: slice — slice 144

**Verdict:** PASS
**Model:** minimax/minimax-m2.7

## Findings

### [PASS] Action protocol implementation matches architecture definition

The `Action` protocol as defined in the slice (via `ActionType`, `ActionContext`, `ActionResult`, `validate()`, `execute()`) aligns with the architecture's protocol definition in the Core Abstraction: Actions section. Each action implements all required protocol methods with appropriate signatures.

### [PASS] Component structure matches architecture specification

The slice's proposed package structure:
```
src/squadron/pipeline/actions/
├── cf_op.py        # CfOpAction
├── commit.py       # CommitAction
└── devlog.py       # DevlogAction
```
Matches exactly the architecture's Component Architecture diagram, which lists `cf_op.py`, `commit.py`, and `devlog.py` under the actions directory.

### [PASS] Core Action Types are correctly implemented

All three action types specified in the architecture's Core Action Types table are implemented:
- **`cf-op`**: Defined as "Context Forge operation (set phase, build, summarize, query)" — slice implements `set_phase`, `build_context`, and `summarize` operations
- **`commit`**: Defined as "Git commit at a boundary" — slice implements full git staging and commit flow
- **`devlog`**: Defined as "Write structured DEVLOG entry" — slice implements DEVLOG entry generation and insertion

### [PASS] Dependency directions are correct

The slice correctly declares dependencies on slices that the architecture identifies as prerequisites:
- **Slice 142 (Pipeline Core Models)** — consumed as the source of the `Action` protocol, `ActionType`, `ActionContext`, `ActionResult`, and `register_action()` function
- **Slice 126 (CF Integration)** — consumed as the source of `ContextForgeClient`

No backward dependencies or unexpected dependencies are introduced.

### [PASS] Integration points align with downstream consumers

The slice explicitly documents providing to:
- **Slice 147 (Compact Action and Step Types)**: The phase step type expands to include `cf-op`, `commit`, and `devlog` — exactly what slice 144 implements
- **Slice 149 (Pipeline Executor)**: Iterates action sequences and calls `action.execute()` — will use these first concrete implementations

This matches the architecture's stated dependency chain where these slices consume the action implementations.

### [PASS] Correctly scoped to architecture boundaries

The slice explicitly excludes from scope:
- Step type implementations (slice 147) — correctly delegated
- Pipeline executor integration (slice 149) — correctly deferred
- CF client modifications — correctly consumes existing interface

This maintains the layer boundaries defined in the architecture's Scope Boundaries section.

### [PASS] Auto-registration pattern matches architecture extension model

The auto-registration pattern (`register_action(ActionType.X, XAction())`) at module import time matches the architecture's "Action Extensibility" principle and mirrors the existing provider registry pattern. This enables both built-in actions and future custom actions to be registered uniformly.

### [PASS] Technical decisions align with architecture rationale

The decision to have `CfOpAction` call `cf_client._run()` directly rather than adding new public methods to `ContextForgeClient` is sound. The architecture explicitly notes that "these are pipeline-specific orchestration methods that don't belong on a general-purpose CF client" — the slice's rationale matches this exactly.
