feat: Add speckit metadata support in pyproject.toml

NeilJo-GY · NeilJo-GY · commit 51f4788b80a1 · 2025-11-22T12:34:44.000+08:00
## Features

Add [tool.metaspec] metadata section to enable community discovery:
- generated_by: MetaSpec version
- domain: Toolkit domain
- lifecycle: Optional (greenfield/brownfield, omitted for non-dev domains)
- sd_type: Command system type (updated during implementation)
- slash_commands: Deployed AI commands list

## Two-Phase Implementation

### Phase 1: Initialization (pyproject.toml.j2)
- Provides base framework with placeholder values
- sd_type = 'tbd' or 'none' (to be updated)
- slash_commands section commented out

### Phase 2: Implementation (implement.md.j2)
- AI updates metadata during toolkit implementation
- Scans .metaspec/commands/ for actual deployed commands
- Calculates sd_type from command sources
- Populates slash_commands array

## Files Modified

- src/metaspec/templates/base/pyproject.toml.j2
  * Add [tool.metaspec] section with placeholder values
  * Simplified (no complex Jinja2 logic)

- src/metaspec/templates/meta/sdd/commands/implement.md.j2
  * Add Python pyproject.toml update guidance (92 lines)
  * Include sd_type calculation rules
  * Update navigation guide (all line numbers corrected)

- src/metaspec/models.py
  * Add lifecycle field to MetaSpecDefinition
  * Update from_dict to parse lifecycle

- src/metaspec/generator.py
  * Pass lifecycle to template context

- src/metaspec/cli/init.py
  * Add lifecycle to default preset

- src/metaspec/templates/base/{README,AGENTS}.md.j2
  * Make lifecycle display optional

- docs/metaspec-metadata-examples.md (new)
  * Comprehensive metadata documentation
  * 5 real-world examples
  * Auto-detection rules
  * Community use cases

## Token Savings

implement.md.j2 navigation improvements:
- Language-specific reading: 8 lines (~30 tokens) → 99% savings 🏆
- Python + pyproject.toml: 92 lines (~320 tokens) → 91% savings

+# MetaSpec Metadata in pyproject.toml
+
+> **Purpose**: Enable community tools to discover speckit capabilities
+
+生成的 speckit 的 `pyproject.toml` 会包含 `[tool.metaspec]` 部分，记录 speckit 的元数据。
+
+---
+
+## 📋 Metadata Fields
+
+### Core Fields (Always Present)
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `generated_by` | string | MetaSpec version used to generate this speckit |
+| `domain` | string | Domain area (e.g., "mcp", "testing", "marketing") |
+
+### Optional Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `lifecycle` | string | Development phase: "greenfield" (0→1) \| "brownfield" (1→n) \| custom |
+| `sd_type` | string \| array | Command system type(s): "generic" \| "sds" \| "sdd" \| mixed |
+| `slash_commands` | array | Deployed AI slash commands |
+
+---
+
+## 📝 Example Outputs
+
+### Example 1: Generic Speckit (No Slash Commands)
+
+```toml
+[tool.metaspec]
+generated_by = "0.9.5"
+domain = "generic"
+lifecycle = "greenfield"
+
+# No slash commands deployed
+sd_type = "none"
+```
+
+**Scenario**: Simple speckit without AI commands (just CLI)
+
+---
+
+### Example 2: SDD Toolkit (Greenfield Development)
+
+```toml
+[tool.metaspec]
+generated_by = "0.9.5"
+domain = "mcp"
+lifecycle = "greenfield"
+
+# Command system type (auto-detected)
+sd_type = "sdd"
+
+# Deployed slash commands
+[[tool.metaspec.slash_commands]]
+name = "specify"
+description = "Create feature specification"
+source = "sdd/spec-kit"
+
+[[tool.metaspec.slash_commands]]
+name = "plan"
+description = "Plan implementation architecture"
+source = "sdd/spec-kit"
+
+[[tool.metaspec.slash_commands]]
+name = "implement"
+description = "Execute implementation"
+source = "sdd/spec-kit"
+```
+
+**Scenario**: Toolkit using GitHub spec-kit workflow (0→1 development)
+
+---
+
+### Example 3: Mixed SDS + SDD (MetaSpec Itself)
+
+```toml
+[tool.metaspec]
+generated_by = "0.9.5"
+domain = "meta-specification"
+lifecycle = "greenfield"
+
+# Command system type (auto-detected)
+sd_type = ["sds", "sdd"]
+
+# Deployed slash commands (19 total)
+[[tool.metaspec.slash_commands]]
+name = "sds.specify"
+description = "Define domain specification"
+source = "sds"
+
+[[tool.metaspec.slash_commands]]
+name = "sds.plan"
+description = "Plan specification architecture"
+source = "sds"
+
+[[tool.metaspec.slash_commands]]
+name = "sdd.specify"
+description = "Define toolkit specification"
+source = "sdd"
+
+[[tool.metaspec.slash_commands]]
+name = "sdd.implement"
+description = "Build toolkit code"
+source = "sdd"
+
+# ... (15 more commands)
+```
+
+**Scenario**: MetaSpec itself - generates both specifications and toolkits
+
+---
+
+### Example 4: SD-Marketing (Custom Domain, No Lifecycle)
+
+```toml
+[tool.metaspec]
+generated_by = "0.9.5"
+domain = "marketing"
+
+# Command system type (auto-detected)
+sd_type = "generic"
+
+# Deployed slash commands
+[[tool.metaspec.slash_commands]]
+name = "campaign.create"
+description = "Create marketing campaign specification"
+source = "generic"
+
+[[tool.metaspec.slash_commands]]
+name = "campaign.validate"
+description = "Validate campaign against rules"
+source = "generic"
+```
+
+**Scenario**: Marketing toolkit - "lifecycle" doesn't apply to this domain
+
+---
+
+### Example 5: Generic + SDD (Mixed Sources)
+
+```toml
+[tool.metaspec]
+generated_by = "0.9.5"
+domain = "api"
+lifecycle = "greenfield"
+
+# Command system type (auto-detected)
+sd_type = ["generic", "sdd"]
+
+# Deployed slash commands
+[[tool.metaspec.slash_commands]]
+name = "discover"
+description = "Discover API structure"
+source = "generic"
+
+[[tool.metaspec.slash_commands]]
+name = "specify"
+description = "Define API specification"
+source = "sdd/spec-kit"
+
+[[tool.metaspec.slash_commands]]
+name = "generate"
+description = "Generate API client code"
+source = "generic"
+```
+
+**Scenario**: API toolkit combining generic discovery with spec-kit workflow
+
+---
+
+## 🔍 Auto-Detection Rules
+
+### `sd_type` Detection
+
+Based on `slash_commands[].source`:
+
+| Source Pattern | Detected Type |
+|----------------|---------------|
+| `sdd/spec-kit` | `"sdd"` |
+| `sdd/openspec` | `"sdd"` |
+| `sds/*` | `"sds"` |
+| `generic` | `"generic"` |
+| Mixed | `["sds", "sdd"]` or `["generic", "sdd"]` etc. |
+
+### `lifecycle` Usage
+
+- ✅ **Applicable**: Software development domains (API, testing, frameworks)
+  - `greenfield`: Creating new features/projects (0→1)
+  - `brownfield`: Evolving existing systems (1→n)
+
+- ⚠️ **Not Applicable**: Non-development domains (marketing, design, operations)
+  - Leave `lifecycle` undefined (optional field)
+  - Focus on `sd_type` and `domain` instead
+
+---
+
+## 🎯 Community Use Cases
+
+### Use Case 1: Speckit Registry
+
+```python
+# Read speckit metadata
+import toml
+
+config = toml.load("pyproject.toml")
+metadata = config["tool"]["metaspec"]
+
+print(f"Domain: {metadata['domain']}")
+print(f"Command System: {metadata['sd_type']}")
+print(f"Slash Commands: {len(metadata.get('slash_commands', []))}")
+```
+
+### Use Case 2: Search by Command Type
+
+```bash
+# Find all SDD toolkits
+rg -A 5 'sd_type = "sdd"' **/pyproject.toml
+
+# Find toolkits with specific commands
+rg -A 10 'name = "specify"' **/pyproject.toml
+```
+
+### Use Case 3: Compatibility Check
+
+```python
+# Check if speckit has required commands
+required_commands = {"specify", "plan", "implement"}
+deployed = {cmd["name"] for cmd in metadata["slash_commands"]}
+
+if required_commands.issubset(deployed):
+    print("✅ Compatible")
+```
+
+---
+
+## 📌 Design Principles
+
+1. **Auto-Detection**: `sd_type` automatically inferred from `slash_commands`
+2. **Optional Fields**: `lifecycle` only for applicable domains
+3. **Community Discovery**: Standardized format for registry tools
+4. **Backward Compatibility**: Minimal required fields
+5. **Flexibility**: Supports mixed command systems and custom domains
