"""Agent Capability Metrics — Collection, Analysis, and Reporting.
|
||
|
||
Core components:
|
||
1. CapabilityMetrics: data model for a single test observation
|
||
2. MetricsCollector: session-scoped collector that gathers all observations
|
||
3. MetricsAnalyzer: computes recall/precision/F1, overfitting scores, weakness analysis
|
||
4. MetricsReporter: generates human-readable and machine-readable reports
|
||
|
||
Design:
|
||
- Collector is a pytest fixture (session-scoped), injected into capability tests
|
||
- Each test records what actually happened vs what was expected
|
||
- After all tests, analyzer computes aggregate metrics
|
||
- Reporter outputs JSON + plain-text summary
