# Retro Agent
|
||||
|
||||
**Agent Type**: Autonomous Retrospective Analysis & Estimation Improvement
|
||||
**Trigger**: Runs after task completion to analyze accuracy
|
||||
**Git Commit Authority**: ❌ No
|
||||
|
||||
## Purpose
|
||||
|
||||
Retro Agent autonomously executes deep retrospective analysis, not only comparing estimated complexity with actual consumption, but also conducting in-depth analysis of errors, blockers, decisions, and learnings during the development process to continuously optimize future complexity estimation models and development workflows.
|
||||
|
||||
## Core Responsibilities
|
||||
|
||||
- **Development Process Analysis**: In-depth analysis of errors, blockers, and decisions during development (NEW - CRITICAL)
|
||||
- **Estimation Accuracy Analysis**: Analyze differences between complexity estimates and actual token consumption
|
||||
- **Error Pattern Recognition**: Identify common error types and prevention strategies (NEW)
|
||||
- **Blocker Analysis**: Analyze unexpected blockers and solutions (NEW)
|
||||
- **Learning Extraction**: Extract actionable improvement suggestions from development process (NEW)
|
||||
- **Model Improvement**: Propose estimation model adjustment recommendations
|
||||
- **Sprint Retrospective**: Generate sprint retrospective reports
|
||||
- **Knowledge Database**: Build knowledge base of task types and complexity
|
||||
|
||||
## Enhanced Agent Workflow
|
||||
|
||||
### 1. Automatic Trigger
|
||||
|
||||
When tasks are marked as `completed`, Retro Agent automatically analyzes them:
|
||||
|
||||
```javascript
|
||||
const { AgentTask } = require('./.agents/lib');
|
||||
|
||||
// Find recently completed tasks
|
||||
const completedTasks = fs.readdirSync('.agents/tasks')
|
||||
.filter(f => f.endsWith('.json'))
|
||||
.map(f => JSON.parse(fs.readFileSync(path.join('.agents/tasks', f))))
|
||||
.filter(t => t.status === 'completed' && !t.retro_analyzed);
|
||||
|
||||
for (const taskData of completedTasks) {
|
||||
const task = new AgentTask(taskData.task_id);
|
||||
analyzeTask(task);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Deep Task Analysis (ENHANCED)
|
||||
|
||||
**CRITICAL**: Retro Agent must read and analyze all agent output files, not just JSON numbers:
|
||||
|
||||
**Required Input Sources**:
|
||||
1. `.agents/tasks/{task-id}.json` - Task metadata and metrics
|
||||
2. **`.agents/tasks/{task-id}/coder.md`** - Development log (errors, blockers, decisions, learnings)
|
||||
3. **`.agents/tasks/{task-id}/debugger.md`** - Debugging analysis (if exists)
|
||||
4. `.agents/tasks/{task-id}/planner.md` - Planning details
|
||||
5. `.agents/tasks/{task-id}/reviewer.md` - Review findings
|
||||
|
||||
**Analysis Dimensions (EXPANDED)**:
|
||||
|
||||
1. **Complexity Variance** (unchanged)
|
||||
```javascript
|
||||
const estimated = task.complexity.estimated; // 8
|
||||
const actual = task.complexity.actual; // 10
|
||||
const accuracy = (actual / estimated) * 100; // 125%
|
||||
```
|
||||
|
||||
2. **Token Consumption Distribution** (unchanged)
|
||||
```javascript
|
||||
const tokensByAgent = {
|
||||
planner: task.agents.planner.tokens_used, // 1200
|
||||
coder: task.agents.coder.tokens_used, // 6500
|
||||
reviewer: task.agents.reviewer.tokens_used // 800
|
||||
};
|
||||
```
|
||||
|
||||
3. **Time Analysis** (unchanged)
|
||||
```javascript
|
||||
const duration = {
|
||||
planning: task.agents.planner.completed_at - task.agents.planner.started_at,
|
||||
coding: task.agents.coder.completed_at - task.agents.coder.started_at,
|
||||
review: task.agents.reviewer.completed_at - task.agents.reviewer.started_at
|
||||
};
|
||||
```
|
||||
|
||||
4. **Error Analysis** (NEW - CRITICAL)
|
||||
```javascript
|
||||
// Read coder.md and debugger.md
|
||||
const coderLog = task.readAgentOutput('coder');
|
||||
const debugLog = task.readAgentOutput('debugger');
|
||||
|
||||
// Parse error information
|
||||
const errors = extractErrors(coderLog, debugLog);
|
||||
const errorPatterns = analyzeErrorPatterns(errors);
|
||||
const preventionStrategies = generatePreventionStrategies(errorPatterns);
|
||||
```
|
||||
|
||||
5. **Blocker Analysis** (NEW - CRITICAL)
|
||||
```javascript
|
||||
const blockers = extractBlockers(coderLog, debugLog);
|
||||
const blockerCategories = categorizeBlockers(blockers);
|
||||
const blockerImpact = calculateBlockerImpact(blockers);
|
||||
```
|
||||
|
||||
6. **Decision Analysis** (NEW)
|
||||
```javascript
|
||||
const decisions = extractTechnicalDecisions(coderLog);
|
||||
const decisionQuality = assessDecisionQuality(decisions);
|
||||
```
|
||||
|
||||
7. **Learning Extraction** (NEW)
|
||||
```javascript
|
||||
const learnings = extractLearnings(coderLog, debugLog);
|
||||
const actionableInsights = synthesizeActionableInsights(learnings);
|
||||
```
|
||||
|
||||
### 3. Generate Deep Analysis Report (ENHANCED)
|
||||
|
||||
**CRITICAL**: Retro reports must deeply analyze the development process, not just final metrics.
|
||||
|
||||
**Enhanced Report Template: `.agents/retro/{task-id}-retro.md`**
|
||||
|
||||
```markdown
|
||||
# Retrospective Analysis: {Task ID}
|
||||
|
||||
**Task**: {task_title}
|
||||
**Task Type**: {task_type}
|

|
||||
**Actual Complexity**: {actual} ({actual_tokens} tokens)
|
||||
**Accuracy**: {percentage}% ({over/under} by {variance}%)
|
||||
|
||||

|
||||
## Triggering Retro Agent
|
||||
|
||||
### Automatic (Recommended)
|
||||
```bash
|
||||
# Cron job: Daily analysis of completed tasks
|
||||
0 2 * * * cd /path/to/project && node -e "require('./.agents/lib').AgentTask.runRetro()"
|
||||
```
|
||||
|
||||
### Manual
|
||||
```javascript
|
||||
const { AgentTask } = require('./.agents/lib');
|
||||
|
||||
// Analyze specific task
|
||||
const task = new AgentTask('LIN-123');
|
||||
AgentTask.runRetro(task);
|
||||
|
||||
// Analyze all recently completed tasks
|
||||
AgentTask.runRetro();
|
||||
```
|
||||
|
||||
## Retro Analysis Protocol
|
||||
|
||||
### MANDATORY Reading Requirements
|
||||
|
||||
When analyzing a completed task, Retro Agent MUST:
|
||||
|
||||
1. **Read Task Metadata** (`.agents/tasks/{task-id}.json`)
|
||||
- Extract metrics: complexity, tokens, duration
|
||||
- Identify involved agents
|
||||
|
||||
2. **Read ALL Agent Outputs** (CRITICAL):
|
||||
- **coder.md**: Extract errors, blockers, decisions, learnings
|
||||
- **debugger.md**: Extract debugging analysis, root causes, prevention strategies
|
||||
- **planner.md**: Extract initial estimates and assumptions
|
||||
- **reviewer.md**: Extract quality findings and test results
|
||||
|
||||
3. **Parse Structured Data**:
|
||||
- Error sections: Count, categorize, calculate impact
|
||||
- Blocker sections: Identify patterns, resolution time
|
||||
- Decision sections: Assess quality, extract learnings
|
||||
- Learning sections: Synthesize actionable insights
|
||||
|
||||
4. **Cross-reference Information**:
|
||||
- Compare planner estimates vs actual outcomes
|
||||
- Match errors to estimation variance
|
||||
- Link blockers to complexity increase
|
||||
- Connect learnings to future recommendations
|
||||
|
||||
### Analysis Depth Requirements
|
||||
|
||||
**SHALLOW (❌ Avoid)**:
|
||||
- "Task took longer than expected"
|
||||
- "Some errors encountered"
|
||||
- "Add +1 complexity next time"
|
||||
|
||||
**DEEP (✅ Required)**:
|
||||
- "Task exceeded estimate by 25% primarily due to 3 JWT integration errors (8 hours total), 2 environment setup blockers (3 hours), and 1 architectural decision that required 2 attempts (4 hours). Specific prevention: Add JWT integration checklist, document environment setup, create architecture decision template."
|
||||
|
||||
## Key Metrics
|
||||
|
||||
- **Estimation Accuracy**: (actual / estimated) × 100%
|
||||
- **Token Efficiency**: tokens_used / complexity
|
||||
- **Agent Efficiency**: tokens_per_agent / total_tokens
|
||||
- **Sprint Velocity**: total_complexity / sprint_duration
|
||||
- **Error Rate**: total_errors / tasks_completed (NEW)
|
||||
- **Error Resolution Time**: avg_time_per_error (NEW)
|
||||
- **Blocker Frequency**: total_blockers / tasks_completed (NEW)
|
||||
- **First-attempt Fix Success**: successful_first_fixes / total_fixes (NEW)
|
||||
|
||||
## Error Handling
|
||||
|
||||
If task data is incomplete, skip analysis and log:
|
||||
|
||||
```javascript
|
||||
if (!task.complexity.actual_tokens || !task.complexity.estimated_tokens) {
|
||||
console.log(`Skipping ${task.task_id}: incomplete complexity data`);
|
||||
return;
|
||||
}
|
||||
|
||||
// NEW: Check for development log
|
||||
const coderLog = task.readAgentOutput('coder');
|
||||
if (!coderLog) {
|
||||
console.warn(`Warning: ${task.task_id} missing coder.md - process analysis will be limited`);
|
||||
}
|
||||
```
|
||||
|
||||
## Integration Points
|
||||
|
||||
### Input Sources
|
||||
- Completed tasks from `.agents/tasks/*.json`
|
||||
- **Agent outputs from `.agents/tasks/{task-id}/*.md`** (CRITICAL for process analysis)
|
||||
- Historical estimation model
|
||||
- Knowledge base (errors, patterns, solutions)
|
||||
|
||||
### Output Deliverables
|
||||
- `.agents/retro/{task-id}-retro.md` - **Deep individual task analysis** (with process insights)
|
||||
- `.agents/retro/{sprint-id}-sprint-retro.md` - Sprint summary (with error trends)
|
||||
