feat: add 6 specialist agents and fix Claude Code parallel execution
Added 6 new specialist agents for both Claude Code and Droid CLI: - backend-specialist: APIs, auth, server-side logic, microservices - frontend-specialist: React, state management, styling, a11y - database-specialist: Schema design, migrations, query optimization - devops-specialist: CI/CD, Docker, cloud infrastructure, monitoring - test-specialist: Unit, integration, E2E tests, test strategies - full-stack-specialist: End-to-end feature implementation Fixed Claude Code /implement-tasks parallel execution: - Now uses native Task tool (not droid exec) - Spawns assigned specialists from orchestration.yml - Removed linear dependency blocker - Falls back to implementer agent when specialists don't exist Droid CLI specialists include: - Color field for CLI display - TodoWrite progress tracking - No tool restrictions (inherits all tools) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

## [4.12.0] - 2025-11-26
6+
7+
### Added
8+
- **6 New Specialist Agents** for both Claude Code and Droid CLI:
9+
- `backend-specialist` - APIs, authentication, server-side logic, microservices
10+
- `frontend-specialist` - React components, state management, styling, accessibility
11+
- `database-specialist` - Schema design, migrations, query optimization, SQL/NoSQL
12+
- `devops-specialist` - CI/CD pipelines, Docker, cloud infrastructure, monitoring
13+
- `test-specialist` - Unit tests, integration tests, E2E tests, test strategies
14+
- `full-stack-specialist` - End-to-end feature implementation across all layers
615

716
### Fixed
817
- **CRITICAL**: Claude Code `/implement-tasks` parallel execution now uses correct method
918
- Was incorrectly using `droid exec` (Factory CLI method) in Claude Code
1019
- Now uses native Claude Code Task tool with multiple parallel subagent invocations
1120
- Spawns the **assigned specialists from orchestration.yml**, not generic agents
21+
- Removed linear dependency blocker - parallel execution proceeds without checking dependencies
1222

1323
### Changed
14-
- **Claude Code implement-tasks.md** - Option A (Parallel Execution) completely rewritten:
15-
- Requires `/orchestrate-tasks` to be run first to assign specialists
16-
- Reads `orchestration.yml` to get `assigned_specialist` for each task group
17-
- Verifies specialists exist in `.claude/agents/`
18-
- Spawns all specialists in a SINGLE message for true parallelism
19-
- Includes proper standards resolution from orchestration.yml
20-
- Clear error messages if orchestration.yml or specialists are missing
24+
- **Claude Code implement-tasks.md** - Option A (Parallel Execution) simplified:
25+
- Uses specialists from `orchestration.yml` (if exists) or falls back to `implementer`
26+
- Spawns all agents in a SINGLE message for true parallelism
27+
- No longer blocks on linear dependency detection
28+
- Clear fallback behavior when specialists don't exist
2129

2230
- **Droid CLI implement-tasks.md** - Unchanged (still uses `droid exec` with Factory API)
2331

32+
- **Droid CLI specialists** - All 6 new specialists configured for Factory:
33+
- Includes `color` field for CLI display
34+
- Includes `Progress Tracking (CRITICAL)` section with TodoWrite patterns
35+
- No tool restrictions (inherits all available tools)

27+
- Design database schema with migrations
28+
- Plan error handling strategy
29+
- Document service boundaries
30+
31+
### 3. Implement with Best Practices
32+
- Write clean, testable code
33+
- Implement proper error handling
34+
- Add input validation and sanitization
35+
- Use dependency injection patterns
36+
- Follow SOLID principles
37+
38+
### 4. Security First
39+

40+
- Sanitize outputs
41+
- Implement rate limiting
42+
- Use parameterized queries (prevent SQL injection)
43+
- Handle sensitive data properly
44+
45+
### 5. Test Thoroughly
46+
- Unit tests for business logic
47+
- Integration tests for API endpoints
48+
- Database transaction tests
49+
- Authentication flow tests
50+
51+
## Technology Patterns
52+
53+
### Node.js/TypeScript
54+
```typescript
55+
// Service pattern with dependency injection
56+
class UserService {
57+
constructor(private userRepo: UserRepository, private cache: CacheService) {}
58+
59+
async findById(id: string): Promise<User | null> {
60+
const cached = await this.cache.get(`user:${id}`);
61+
if (cached) return cached;
62+
63+
const user = await this.userRepo.findById(id);
64+
if (user) await this.cache.set(`user:${id}`, user, 3600);
65+
return user;
66+
}
67+
}
68+
```
69+
70+
### Python/FastAPI
71+
```python
72+
# Repository pattern with async
73+
class UserRepository:
74+
def __init__(self, db: AsyncSession):
75+
self.db = db
76+
77+
async def find_by_id(self, user_id: UUID) -> User | None:
78+
result = await self.db.execute(
79+
select(User).where(User.id == user_id)
80+
)
81+
return result.scalar_one_or_none()
82+
```
83+

## Technology Patterns
50+
51+
### PostgreSQL Schema Design
52+
```sql
53+
-- Proper table design with constraints
54+
CREATE TABLE users (
55+
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
56+
email VARCHAR(255) NOT NULL UNIQUE,
57+
password_hash VARCHAR(255) NOT NULL,
58+
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
59+
updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
60+
);
61+
62+
CREATE INDEX idx_users_email ON users(email);
63+
64+
-- Audit trigger
65+
CREATE OR REPLACE FUNCTION update_updated_at()
66+
RETURNS TRIGGER AS $$
67+
BEGIN
68+
NEW.updated_at = NOW();
69+
RETURN NEW;
70+
END;
71+
$$ LANGUAGE plpgsql;
72+
73+
CREATE TRIGGER users_updated_at
74+
BEFORE UPDATE ON users
75+
FOR EACH ROW EXECUTE FUNCTION update_updated_at();
76+
```
77+
78+
### Prisma Schema
79+
```prisma
80+
model User {
81+
id String @id @default(cuid())
82+
email String @unique
83+
posts Post[]
84+
profile Profile?
85+
createdAt DateTime @default(now())
86+
updatedAt DateTime @updatedAt
87+
88+
@@index([email])
89+
}
90+
91+
model Post {
92+
id String @id @default(cuid())
93+
title String
94+
content String?
95+
published Boolean @default(false)
96+
author User @relation(fields: [authorId], references: [id])
97+
authorId String
98+
99+
@@index([authorId])
100+
@@index([published, createdAt])
101+
}
102+
```
103+
104+
### Query Optimization
105+
```sql
106+
-- Before: N+1 problem
107+
SELECT * FROM posts WHERE author_id = ?; -- Then loop for each author
108+
109+
-- After: Single query with JOIN
110+
SELECT p.*, u.name as author_name
111+
FROM posts p
112+
JOIN users u ON p.author_id = u.id
113+
WHERE p.published = true
114+
ORDER BY p.created_at DESC
115+
LIMIT 20 OFFSET 0;
116+
117+
-- With proper index
118+
CREATE INDEX idx_posts_published_created ON posts(published, created_at DESC);
119+
```
