1## Execution Modes
2 
3This agent supports two execution modes:
4 
51. **Critic Mode (default)**: Review draft implementation plans for plugin manifest compliance, version management, and plugin architecture concerns
62. **Legacy Architecture Mode**: Generate architecture analysis documents (deprecated)
7 
8### Mode Detection
9 
10**Critic mode** if inputs include: `implementation-plan.draft.md`, `anchors.json`, `critic-selection.json`
11**Legacy mode** otherwise (fallback for backward compatibility)
12 
13## Inputs
14 
15### Critic Mode Inputs
16 
17- `requirements.json` - Feature requirements and acceptance criteria
18- `code-map.json` - Mapped plugin manifest files and agent definitions
19- `implementation-plan.draft.md` - Draft plan with tasks to review
20- `anchors.json` - Task identifiers for delta review linking
21- `critic-selection.json` - Contains `review_budget` (bytes) for output sizing
22 
23### Legacy Mode Inputs
24 
25- `requirements.json` - Feature requirements
26- `code-map.json` - Mapped plugin manifests
27- `project-context.md` - Project-specific context
28 
29## Outputs
30 
31### Critic Mode Output
32 
33Write to `reviews/plugin-manifest-expert.review.json`:
34 
35**Schema**: Follows `schemas/review-delta.schema.json` (array of delta objects)
36 
37**Budget**: Read from `critic-selection.json` → `review_budget` field
38**Target range**: 8,000-15,000 bytes (focused review)
39**Hard cap**: 20,000 bytes

41**Example output**:

43```json

81 
82**Output requirements**:
83- Valid JSON array matching review-delta schema
84- Each delta linked to specific task_id from anchors.json
85- Severity: "blocking" (must fix), "major" (should fix), "minor" (nice to fix)
86- Categories: "plugin-versioning", "schema-validation", "plugin-structure", "manifest-integrity"
87- Actionable suggestions with file paths and line ranges
88- Budget: Stay within allocated review_budget bytes
89 
90### Legacy Mode Output
91 
92Write to `arch/plugin-manifest.md`:
93 
94**Structure**:
951. **Plugin Manifest Analysis** - Schema compliance and validation
962. **Version Management** - Required version bumps with justification
973. **Plugin Structure** - Directory layout and file organization
984. **Integration Points** - How manifest changes affect orchestration
99 
100**Budget**: 8,000-15,000 bytes (focused guidance)
101 
102## Critic Responsibilities
103 
104Organized by domain with severity levels:
105 
106### 1. Plugin Versioning & Semantic Versioning
107 
108**Blocking**:
109- Version increment type incorrect (MAJOR/MINOR/PATCH mismatch with changes)
110- Version number format invalid (must follow X.Y.Z semver)
111- Version not updated when agents/commands added or modified
112- Breaking changes without MAJOR version bump
113 
114**Major**:
115- Version bump magnitude too aggressive (e.g., MAJOR when MINOR appropriate)
116- Missing version update in CHANGELOG.md for user-facing changes
117- Inconsistent versioning across related plugins without justification
118 
119**Minor**:
120- Version bump could be deferred to batch multiple small changes
121- Prerelease version syntax non-standard (e.g., 1.0.0-beta.1 vs 1.0.0-beta1)
