# Agent Metrics Collection Utility

## Purpose

This utility collects and reports metrics on agent usage from git history. It implements the 8 key metrics defined in `docs/agent-metrics.md` for measuring agent system health, effectiveness, and adoption.

## Available Scripts

| Script | Platform | Usage |
|--------|----------|-------|
| `collect_metrics.py` | Python 3.8+ | Cross-platform |
| `collect-metrics.ps1` | PowerShell 5.1+ | Windows/Linux/macOS |

## Quick Start

### Python

```bash
# Basic usage (30 days, summary output)
python .claude/skills/metrics/collect_metrics.py

# Last 90 days as markdown
python .claude/skills/metrics/collect_metrics.py --since 90 --output markdown

# JSON output for automation
python .claude/skills/metrics/collect_metrics.py --output json
```

### PowerShell

```powershell
# Basic usage (30 days, summary output)
.\.agents\utilities\metrics\collect-metrics.ps1

# Last 90 days as markdown
.\.agents\utilities\metrics\collect-metrics.ps1 -Since 90 -Output Markdown

# JSON output for automation
.\.agents\utilities\metrics\collect-metrics.ps1 -Output Json | ConvertFrom-Json
```

## Metrics Collected

The utility collects the following metrics:

| Metric | Description | Target |
|--------|-------------|--------|
| Metric 1: Invocation Rate | Agent usage distribution | Proportional to task types |
| Metric 2: Agent Coverage | % of commits with agent involvement | 50% |
| Metric 4: Infrastructure Review | % of infra changes with security review | 100% |
| Metric 5: Usage Distribution | Agent utilization patterns | Balanced distribution |

## Detection Patterns

### Agent Detection

The utility detects agents in commit messages using these patterns:

- Direct agent names: `orchestrator`, `analyst`, `architect`, etc.
- Review attribution: `Reviewed by: security`
- Agent tags: `agent: implementer` or `[security-agent]`

### Infrastructure Files

Infrastructure commits are identified by these patterns:

- `.github/workflows/*.yml`
- `.githooks/*`
- `Dockerfile*`
- `*.tf`, `*.tfvars`
- `.env*`
- `.agents/*`

### Commit Types

Conventional commit prefixes are classified:

- `feat:` - Feature
- `fix:` - Bug fix
- `docs:` - Documentation
- `ci:` - CI/CD
- `refactor:` - Refactoring

## Output Formats

### Summary (Default)

Human-readable console output with key metrics highlighted.

### Markdown

Formatted markdown suitable for dashboards and reports. Can be saved directly to `.agents/metrics/` for archival.

### JSON

Structured data for programmatic consumption and CI integration.

## CI Integration

See `.github/workflows/agent-metrics.yml` for automated weekly metrics collection.

The workflow:

1. Runs weekly on Sundays
2. Collects metrics for the previous 7 days
3. Generates a markdown report
4. Creates a PR with the report (if significant changes)

## Manual Report Generation

To generate a monthly dashboard report:

```bash
# Generate report
python .claude/skills/metrics/collect_metrics.py \
    --since 30 \
    --output markdown \
    > .agents/metrics/report-$(date +%Y-%m).md

# Review and commit
git add .agents/metrics/
git commit -m "docs(metrics): add monthly metrics report"
```

## Extending the Utility

### Adding New Metrics

1. Define the metric in `docs/agent-metrics.md`
2. Add collection logic to both scripts
3. Update the output formatters
4. Add tests if applicable

### Adding New Agent Patterns

Update the `AGENT_PATTERNS` / `$AgentPatterns` arrays to detect new agent references.

### Adding Infrastructure Patterns

Update the `INFRASTRUCTURE_PATTERNS` / `$InfrastructurePatterns` arrays for new infrastructure file types.

## Troubleshooting

### No Agents Detected

- Ensure commit messages reference agents explicitly
- Check that conventional commit format is used
- Verify the patterns match your team's conventions

### Git Errors

- Confirm you're in a git repository
- Check that the repository has commits in the date range
- Verify git is available in PATH
