## Key Features
|
|
|
|
### Stage-Gate Architecture
|
|
|
|
Hard-gate blocks enforce sequential execution:
|
|
|
|
```
|
|
ipa-spec ✓ (no prerequisites)
|
|
↓
|
|
ipa-design (requires SRD.md)
|
|
↓
|
|
ipa-detail (requires UI_SPEC.md)
|
|
↓
|
|
ipa-validate (requires API_SPEC.md + DB_DESIGN.md)
|
|
```
|
|
|
|
Each skill checks for required files before executing and returns clear error messages if gates aren't satisfied.
|
|
|
|
### Template System
|
|
|
|
Four core doc templates provided:
|
|
|
|
| Template | Purpose | Sections |
|
|
|----------|---------|----------|
|
|
| `SRD.md` | Requirements | Overview, Features, User Stories, Constraints |
|
|
| `UI_SPEC.md` | UI Design | Wireframes, Flows, Component Library, Responsive |
|
|
| `API_SPEC.md` | API Definition | Endpoints, Request/Response, Authentication, Errors |
|
|
| `DB_DESIGN.md` | Database | Schema, Relationships, Indexes, Migrations |
|
|
|
|
### Installation System
|
|
|
|
**Bash (Linux/macOS):**
|
|
```bash
|
|
./install.sh --global # ~/.gemini/antigravity/skills/
|
|
./install.sh --workspace # ./.agent/skills/ + doc templates
|
|
```
|
|
|
|
**PowerShell (Windows):**
|
|
```powershell
|
|
.\install.ps1 # Global install
|
|
.\install.ps1 -Workspace # Workspace install
|
|
```
|
|
|
|
## Skill Metadata
|
|
|
|
All skills use consistent frontmatter format:
|
|
|
|
```json
|
|
{
|
|
"id": "ipa-spec",
|
|
"name": "IPA Spec Generation",
|
|
"category": "ipa-core",
|
|
"version": "1.0.0",
|
|
"triggers": ["spec", "requirements", "srd"],
|
|
"description": "Generate Software Requirements Definition",
|
|
"output": ["SRD.md", "UI_SPEC.md"],

```
|
|
|

|
## Installation & Distribution
|
|
|
|
### Package Contents
|
|
- 24 skill SKILL.md files
|
|
- 4 template doc files (SRD, UI_SPEC, API_SPEC, DB_DESIGN)
|
|
- 1 SKILL.md template for contributors
|
|
- Installation scripts (bash, PowerShell)
|
|
- skills_index.json registry
|
|
|
|
### Distribution Channels
|
|
- GitHub releases (tagged v1.0.0, v1.1.0, etc.)
|
|
- Antigravity marketplace (if available)
|
|
- Manual clone + `./install.sh`
|
|
|
|
## Performance & Scalability
|
|
|
|
### Latency
|
|
- Skill invocation: < 100ms (excluding LLM)
|
|
- Frontmatter parsing: < 50ms per skill
|
|
- Full pipeline (4 stages): 5-15 minutes (LLM-dependent)
|
|
|
|
### Scalability
|
|
- Designed for 1-50 person teams
|
|
- Handles projects up to 100K+ LOC (via doc splitting)
|
|
- Can process 10K+ user stories (ipa-spec batches them)
|
|
|
|
## Security & Privacy
|
|
|
|
### Data Handling
|
|
- No telemetry or tracking
|
|
- User documents stay local (not uploaded)
|
|
- No authentication required
|
|
- Open-source (MIT license)
|
|
|
|
### Code Review
|
|
- Zero hardcoded credentials
|
|
- No shell execution (Antigravity IDE safe)
|
|
- Template files stripped of sensitive data
|
|
|
|
## Known Limitations
|
|
|
|
1. **Hard-gates are advisory** — Enforced by skill logic, not platform
|
|
2. **Single project per workspace** — Multiple projects need separate folders
|
|
3. **No real-time collaboration** — Docs are local files
|
|
4. **Requires Antigravity IDE v1.0+** — Not compatible with ClaudeKit IDE
|
|
5. **Manual doc merge** — No automatic conflict resolution for parallel editing
|
|
|
|
## Future Enhancements (Out of Scope v1.0)
|
|
|
|
- Web UI for pipeline visualization
|
|
- Real-time team collaboration
|
|
- CI/CD integration for automated validation
|
|
- Multi-language support (Japanese, Spanish, French)
|
|
- Custom hard-gate plugins
|
|
- Integration with Jira, GitHub Issues, Notion
|
