# Aura Frog Agent Detector

**Priority:** HIGHEST - Runs FIRST for every message
**Version:** 3.0.0

---

## When to Use

**ALWAYS** - Every user message, no exceptions.

---

## Auto-Complexity Detection

AI auto-detects task complexity. User doesn't need `:fast` or `:hard` variants.

### Complexity Levels

```toon
complexity[3]{level,criteria,approach}:
  Quick,Single file/Simple fix/Clear scope,Direct implementation - skip research
  Standard,2-5 files/Feature add/Some unknowns,Scout first then implement
  Deep,6+ files/Architecture/Vague scope,Research + plan + implement
```

### Auto-Detection Criteria

**Quick (1-2 tool calls):**
- Typo fix, single variable rename
- Add console.log/debugging
- Simple CSS change
- Clear file path given
- "Just do X" explicit instruction

**Standard (3-6 tool calls):**
- New component/function
- Bug fix with clear error
- API endpoint addition
- File modification with tests

**Deep (7+ tool calls, use plan mode):**
- New feature across multiple files
- Refactoring/architecture change
- Vague requirements ("make it better")
- Security audit
- Performance optimization
- User asks to "plan" or "design"

### Detection Logic

```
1. Count mentioned files/components
2. Check for vague vs specific language
3. Detect scope modifiers (all, entire, every)
4. Check for research keywords (how, why, best way)
5. Assign complexity level
```

---

## Model Selection

**Auto-select model based on task complexity and agent type.**

### Model Mapping

```toon
model_selection[3]{model,when_to_use,agents}:
  haiku,Quick tasks/Simple queries/Orchestration,pm-operations-orchestrator/project-detector/voice-operations
  sonnet,Standard implementation/Coding/Testing/Bug fixes,All dev agents/qa-automation/ui-designer
  opus,Architecture/Deep analysis/Security audits/Complex planning,security-expert (audits)/Any agent (architecture mode)
```

### Complexity → Model

```toon
complexity_model[3]{complexity,default_model,override_to_opus}:
  Quick,haiku,Never
  Standard,sonnet,User asks for architecture/design
  Deep,sonnet,Always consider opus for planning phase
```

### Task Type → Model

```toon
task_model[8]{task_type,model,reason}:
  Typo fix / config change,haiku,Minimal reasoning needed
  Bug fix / feature add,sonnet,Standard implementation
  API endpoint / component,sonnet,Standard implementation
  Test writing,sonnet,Requires code understanding
  Code review,sonnet,Pattern matching + analysis
  Architecture design,opus,Complex trade-off analysis
  Security audit,opus,Deep vulnerability analysis
  Refactoring / migration,opus,Cross-cutting impact analysis
```

### Agent Default Models

```toon
agent_models[11]{agent,default_model,opus_when}:
  pm-operations-orchestrator,haiku,Never (orchestration only)
  project-manager,haiku,Never (detection/context loading)
  smart-agent-detector,haiku,Never (routing only)
  architect,sonnet,Schema design / migration planning / system architecture
  ui-expert,sonnet,Design system architecture
  mobile-expert,sonnet,Architecture decisions
  game-developer,sonnet,Game architecture decisions
  security-expert,sonnet,opus for full audits
  qa-automation,sonnet,Never
  devops-cicd,sonnet,Infrastructure architecture
  voice-operations,haiku,Never (notifications only)
```

### Model Selection Output

Include in detection result:

```markdown
## Detection Result
- **Agent:** backend-nodejs
- **Model:** sonnet
- **Complexity:** Standard
- **Reason:** API endpoint implementation
```

When spawning Task tool, use the detected model:
```
Task(subagent_type="backend-nodejs", model="sonnet", ...)
```

## Multi-Layer Detection System

### Layer 0: Task Content Analysis (NEW - Highest Priority)

**Analyze the actual task, not just the repo.** A backend repo may have frontend tasks (templates, PDFs, emails).

**Full patterns:** `task-based-agent-selection.md`

```toon
task_content_triggers[7]{category,example_patterns,activates,score_boost}:
  Frontend,html template/blade/twig/email template/pdf styling/css,ui-expert,+50 to +60
  Backend,api endpoint/controller/middleware/queue job/webhook,architect (+ framework skill),+50 to +55
  Database,migration/schema/query optimization/slow query/n+1,architect,+55 to +60
  Security,xss/sql injection/csrf/vulnerability/auth bypass,security-expert,+55 to +60
  DevOps,docker/kubernetes/ci-cd/terraform/deployment,devops-cicd,+50 to +55
  Testing,unit test/e2e test/coverage/mock/fixture,qa-automation,+45 to +55
  Design,figma/wireframe/design system/accessibility,ui-expert,+50 to +60
```

**Key insight:** Task content score ≥50 → Override or co-lead with repo-based agent.

**Examples:**
```
# Backend repo, but frontend task
Repo: Laravel API
Task: "Fix email template styling"
→ ui-expert (PRIMARY) + architect (SECONDARY)

# Frontend repo, but backend task
Repo: Next.js
Task: "Add rate limiting to API route"
→ architect (PRIMARY) + ui-expert (SECONDARY)
```

---

### Layer 1: Explicit Technology Detection

Check if user **directly mentions** a technology:

```toon
tech_detection[10]{technology,keywords,agent,score}:
  React Native,react-native/expo/RN,mobile-react-native,+60
  Flutter,flutter/dart/bloc,mobile-flutter,+60
  Angular,angular/ngrx/rxjs,web-angular,+60
  Vue.js,vue/vuejs/pinia/nuxt,web-vuejs,+60
  React,react/reactjs/jsx,web-reactjs,+60
  Next.js,next/nextjs/ssr/ssg,web-nextjs,+60
  Node.js,nodejs/express/nestjs/fastify,backend-nodejs,+60
  Python,python/django/fastapi/flask,backend-python,+60
  Go,go/golang/gin/fiber,backend-go,+60
  Laravel,laravel/php/eloquent/artisan,backend-laravel,+60
```

### Layer 2: Intent Detection Patterns

Detect user **intent** from action keywords:

```toon
intent_detection[8]{intent,keywords,primary,secondary}:
  Implementation,implement/create/add/build/develop,Dev agent,ui-designer/qa-automation
  Bug Fix,fix/bug/error/issue/broken/crash,Dev agent,qa-automation
  Testing,test/testing/coverage/QA/spec,qa-automation,Dev agent
  Design/UI,design/UI/UX/layout/figma/style,ui-designer,Dev agent
  Database,database/schema/query/migration/SQL,database-specialist,Backend agent
  Security,security/vulnerability/audit/owasp/secure,security-expert,Dev agent
  Performance,performance/slow/optimize/speed/memory,devops-cicd,Dev agent
  Deployment,deploy/docker/kubernetes/CI-CD/pipeline,devops-cicd,-
```

### Layer 3: Project Context Detection

Read project files to **infer** tech stack:

```toon
project_detection[10]{file,indicates,agent,score}:
  app.json (with expo),React Native,mobile-react-native,+40
  pubspec.yaml,Flutter,mobile-flutter,+40
  angular.json,Angular,web-angular,+40
  *.vue files,Vue.js,web-vuejs,+40
  next.config.js,Next.js,web-nextjs,+40
  package.json + react (no next),React,web-reactjs,+40
  package.json + express/nestjs,Node.js,backend-nodejs,+40
  requirements.txt/pyproject.toml,Python,backend-python,+40
  go.mod/go.sum,Go,backend-go,+40
  artisan/composer.json + laravel,Laravel,backend-laravel,+40
```

### Layer 4: File Pattern Detection

Check **recent files** and naming conventions:

```toon
file_patterns[9]{pattern,agent,score}:
  *.phone.tsx/*.tablet.tsx,mobile-react-native,+20
  *.dart/lib/ folder,mobile-flutter,+20
  *.component.ts/*.service.ts,web-angular,+20
  *.vue,web-vuejs,+20
  app/route.ts (Next.js),web-nextjs,+20
  *.controller.ts/*.module.ts,backend-nodejs,+20
  views.py/models.py,backend-python,+20
  *.go,backend-go,+20
  *Controller.php/*Model.php,backend-laravel,+20
```

---

## Scoring Weights

```toon
weights[9]{criterion,weight,description}:
  Task Content Match,+50-60,Task-based patterns override repo (Layer 0) - HIGHEST PRIORITY
  Explicit Mention,+60,User directly mentions technology
  Keyword Exact Match,+50,Direct keyword match to intent
  Project Context,+40,CWD/file structure/package files
  Semantic Match,+35,Contextual/implied match
  Task Complexity,+30,Inferred complexity level
  Conversation History,+25,Previous context/active agents
  File Patterns,+20,Recent files/naming conventions
  Project Priority Bonus,+25,Agent in project-config.yaml priority list
```

**Task Content Override Rule:** When task content score ≥50 for a different domain than the repo, that domain's agent becomes PRIMARY or co-PRIMARY.

---

## Agent Thresholds

```toon
thresholds[4]{level,score,role}:
  Primary Agent,≥80,Leads the task
  Secondary Agent,50-79,Supporting role
  Optional Agent,30-49,May assist
  Not Activated,<30,Not selected
```

---

## QA Agent Conditional Activation

**qa-automation is ALWAYS Secondary when:**
- Intent = Implementation (+30 pts as secondary)
- Intent = Bug Fix (+35 pts as secondary)
- New feature being created
- Code modification requested

**qa-automation is Primary when:**
- Intent = Testing (keywords: test, coverage, QA)
- User explicitly asks for tests
- Coverage report requested

**qa-automation is SKIPPED when:**
- Pure documentation task
- Pure design discussion (no code)
- Research/exploration only

---

## Detection Process

### Step 0: Task Content Analysis (NEW - Do This First!)

**Analyze the task itself before checking the repo.**

```
User: "Update the invoice PDF layout - table breaks across pages"

Task Analysis:
- "PDF" → Frontend task pattern (+50)
- "layout" → Frontend keyword (+40)
- "table" → Frontend keyword (+30)
→ Total frontend score: 120 pts → web-expert is PRIMARY

Even if repo is pure backend, web-expert leads this task!
```

**Apply patterns from:** `task-based-agent-selection.md`

### Step 1: Extract Keywords
```
User: "Fix the login button not working on iOS"

Extracted:
- Action: "fix" → Bug Fix intent
- Component: "login button" → UI element
- Platform: "iOS" → Mobile
- Issue: "not working" → Bug context
```

### Step 2: Check Project Context (Use Cached Detection!)

**IMPORTANT:** Use cached project detection to avoid re-scanning every task.

```bash
# 1. Check detection first (fast path):
.claude/project-contexts/[project-name]/project-detection.json

# 2. If detection valid (< 24h, key files unchanged):
   → Use cached: framework, agents, testInfra, filePatterns

# 3. If detection invalid or missing:
   → Run full detection (reads package.json, etc.)
   → Save to project-contexts for next task

# 4. Load project-specific overrides:
.claude/project-contexts/[project]/project-config.yaml
.claude/project-contexts/[project]/conventions.md
```

**Detection invalidation triggers:**
- Key config files changed (package.json mtime/size)
- Detection older than 24 hours
- User runs `/project:refresh`

**Commands:**
- `/project:status` - Show project detection
- `/project:refresh` - Force fresh scan

### Step 3: Score All Agents (Combine Task + Repo)
```
mobile-react-native:
  - "iOS" keyword: +35 (semantic)
  - CWD = /mobile-app: +40 (context)
  - Recent *.phone.tsx: +20 (file pattern)
  → Total: 95 pts ✅ PRIMARY

qa-automation:
  - Bug fix intent: +35 (secondary for bugs)
  → Total: 35 pts ✅ OPTIONAL

ui-designer:
  - "button" keyword: +20 (UI element)
  → Total: 20 pts ❌ NOT SELECTED
```

### Step 4: Select Agents
- Primary: Highest score ≥80
- Secondary: Score 50-79
- Optional: Score 30-49

### Step 5: Show Banner

**See:** `rules/agent-identification-banner.md` for official format.

**Single Agent Banner:**
```
⚡ 🐸 AURA FROG v1.2.0 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
┃ Agent: [agent-name] │ Phase: [phase] - [name]          ┃
┃ Model: [model] │ 🔥 [aura-message]                      ┃
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```

**Multi-Agent Banner (when collaboration needed):**
```
⚡ 🐸 AURA FROG v1.2.0 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
┃ Agents: [primary] + [secondary], [tertiary]            ┃
┃ Phase: [phase] - [name] │ 🔥 [aura-message]            ┃
┃ Model: [model]                                         ┃
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```

  ✅ Model: sonnet
  ✅ Complexity: Standard
```

---

## After Detection

1. **Output detection result** with agent, model, and complexity
2. **Load agent instructions** from `agents/[agent-name].md`
3. **Use detected model** when spawning Task tool:
   ```
   Task(subagent_type="[agent]", model="[detected-model]", ...)
   ```
4. **Invoke appropriate skill:**
   - Complex feature → `workflow-orchestrator`
   - Bug fix → `bugfix-quick`
   - Test request → `test-writer`
   - Code review → `code-reviewer`
5. **Always load project context** via `project-context-loader` before major actions

---

## Manual Override

User can force specific agent:
```
User: "Use only qa-automation for this task"
→ Override automatic selection
→ qa-automation becomes PRIMARY regardless of scoring
```

**Full detection algorithm:** `agents/smart-agent-detector.md`
**Selection guide:** `docs/AGENT_SELECTION_GUIDE.md`

**MANDATORY:** Always show agent banner at start of EVERY response.
