+# Database Skill
+
+This skill guides the design of relational database migrations and pgvector vector configurations.
+
+## Schema Migrations
+1. Always enable the pgvector extension using `CREATE EXTENSION IF NOT EXISTS vector;`.
+2. Define core entities using strict UUID primary keys:
+   - `recruiters` (internal user management)
+   - `jobs` (includes UUID, title text, requirements JSONB, and `embedding` vector(1536))
+   - `candidates` (includes UUID, name, contact_info JSONB, and `embedding` vector(1536))
+   - `interviews` (links jobs and candidates, tracks dates, stages, feedback)
+   - `scores` (tracks standard evaluations with ai_score float and structured JSONB evaluation containing summary, classification, suggestions, riskLevel keys)
+3. Enforce schema keys on scores table evaluation column via check constraints.
+
+## Similarity search SQL Function
+Write RPC math function `match_candidates` computing cosine distance using `<=>` operator, formulated exactly as `1 - (candidate.embedding <=> query_embedding)` to return normalized scores.

+
+# Developer Skill
+
+This skill guides the implementation of Next.js frontend pages, whitelisted styles, and dry React components.
+
+## Styling System Whitelist
+You must restrict colors and design tokens to:
+- **Backgrounds:** `bg-slate-50` (layouts), `bg-white` (cards/surfaces)
+- **Text:** `text-slate-900` (headings), `text-slate-600` (body), `text-slate-500` (secondary labels)
+- **Actions:** `bg-blue-600` (primary buttons), `hover:bg-blue-700` (hovers), `text-white` (button text)
+- **Dividers:** `border-slate-200`
+- **Radii:** `rounded-md` or `rounded-lg`
+- **Shadows:** `shadow-sm` (cards), `shadow-md` (modals)
+
+## Domain Layout Structure
+Strictly align routes with business domains:
+- `/app/(dashboard)/jobs`
+- `/app/(dashboard)/candidates`
+- `/app/(dashboard)/interviews`
+- `/app/(dashboard)/workflows`
+
+## Type Safety
+Ensure all page exports and component props are strictly typed. Avoid `any` types. Ensure linter rules are satisfied.

+This skill guides quality validation processes to meet the Definition of Done (DoD).
+
+## Verification Checklist
+- Run `npm run lint` and verify zero errors.
+- Run `npm run build` to ensure Next.js build compilation succeeds.
+- Check Tailwind styling tokens in files using `grep_search` to verify compliance with the styling whitelist.
+- Verify that `pre-commit`, `commit-msg`, and `pre-push` git hooks are present and executable.

+
+# Recruitment Orchestrator
+
+This orchestrator coordinates the recruitment developer, database architect, and QA validator subagents.
+
+## Subagents Team
+
+| Subagent TypeName | Role | Output Artifacts |
+|:---|:---|:---|
+| db-architect | Relational & Vector DB design | `supabase/migrations/` SQL files |
+| recruitment-developer | Front-end Next.js and Components | `/app` layouts, `/components` React pages |
+| qa-validator | Code verification & Git Hooks QA | Build outputs, lint status, hook verification |
+
+## Workflow
+
+### Phase 0: Context Assessment
+1. Check if `supabase/migrations/` or `_workspace/` already exist.
+2. Determine run mode:
+   - **Initial execution**: Generate all schema and scaffold routes.
+   - **Incremental update**: Target only the requested developer/db/QA subagent, keeping existing files intact.
+
+### Phase 1: Database Foundation
+1. Invoke `db-architect` subagent:
+   - Prompt: "Generate schema database migrations in `supabase/migrations/` implementing recruiters, jobs, candidates, interviews, scores with pgvector and similarity search functions."
+2. Await completion and review migration file.
+
+### Phase 2: Frontend Implementation
+1. Invoke `recruitment-developer` subagent:
+   - Prompt: "Create whitelisted Tailwind styled pages in Next.js App Router for jobs, candidates, interviews, workflows. Implement core buttons, status badges, and data card components."
+2. Await completion and review page structures.
+
+### Phase 3: Quality Gates Verification
+1. Invoke `qa-validator` subagent:
+   - Prompt: "Verify formatting/linting status, compile the build, and check git hooks installation. Ensure zero typescript warnings exist."
+2. Await completion and consolidate QA report.
+
+### Phase 4: Final Consolidation
+1. Consolidate results and output the status.
