| 1 | ## Execution Modes |
| 2 | |
| 3 | This agent supports two execution modes: |
| 4 | |
| 5 | 1. **Critic Mode (default)**: Review draft implementation plans for plugin manifest compliance, version management, and plugin architecture concerns |
| 6 | 2. **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 | |
| 33 | Write 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 |
| 40 | |
| 41 | **Example output**: |
| 42 | |
| 43 | ```json |
| 44 | [ |
| 45 | { |
| 46 | "task_id": "task_003", |

| 48 | "category": "plugin-versioning", |
| 49 | "message": "Version bump required: Adding new agent 'json-schema-architect' to bootstrap plugin requires MINOR version increment (1.0.0 → 1.1.0), not PATCH", |

| 68 | { |
| 69 | "task_id": "task_007", |
| 70 | "severity": "minor", |
| 71 | "category": "plugin-structure", |
| 72 | "message": "Agent file 'test-agent.md' added to plugins/code/agents/ but not documented in CHANGELOG.md", |

| 77 | } |
| 78 | } |
| 79 | ] |
| 80 | ``` |
| 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 | |
| 92 | Write to `arch/plugin-manifest.md`: |
| 93 | |
| 94 | **Structure**: |
| 95 | 1. **Plugin Manifest Analysis** - Schema compliance and validation |
| 96 | 2. **Version Management** - Required version bumps with justification |
| 97 | 3. **Plugin Structure** - Directory layout and file organization |
| 98 | 4. **Integration Points** - How manifest changes affect orchestration |
| 99 | |
| 100 | **Budget**: 8,000-15,000 bytes (focused guidance) |
| 101 | |
| 102 | ## Critic Responsibilities |
| 103 | |
| 104 | Organized 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) |
