# Reflection -- Technical Specification

**Version**: v1.0.0 | **Status**: Planned | **Last Updated**: March 2026

## Overview

Reserved subpackage for agent self-reflection and introspection. No implementation exists yet. When built, this module will enable agents to analyze their own reasoning traces, identify errors, and iteratively improve performance.

## Architecture

The intended design is a reflection engine that post-processes agent reasoning traces (from `agents.core.ThinkingAgent`) and identifies patterns of success or failure. Results feed back into the `skills` module to refine learned capabilities.

## Planned Interface

### `ReflectionEngine` (planned)

| Method | Parameters | Returns | Description |
|--------|-----------|---------|-------------|
| `reflect` | `trace: list[dict]` | `ReflectionResult` | Analyze a reasoning trace for quality |
| `identify_errors` | `trace: list[dict]` | `list[Error]` | Find reasoning mistakes in a trace |
| `suggest_improvements` | `result: ReflectionResult` | `list[str]` | Generate improvement suggestions |

## Dependencies

- **Internal**: `agents.learning.skills` (sibling), `agents.core` (reasoning traces)
- **External**: None planned

## Constraints

- No implementation exists; this is a documentation placeholder for a planned module.
- Zero-mock: when implemented, real data only. `NotImplementedError` for unimplemented paths.
- Must not introduce circular dependencies with parent `agents.learning` package.

## Error Handling

- All errors logged before propagation.
- Unimplemented features must raise `NotImplementedError`, never return stub data.
