# Discover Codebase Enhancements

## Overview
Spend significant time crawling and analyzing the codebase to surface high-impact improvements. Center findings on the jobs-to-be-done of the codebase, developers, end users, and AI agents working in the repo.

## Inputs (ask if missing, max 5)
- Target area or scope (whole repo or specific modules)
- Primary user jobs-to-be-done and business goals
- Known pain points or incidents
- Constraints (time, risk tolerance, release window)
- Evidence sources allowed (tests, metrics, logs)

## Jobs-to-Be-Done Lens
- **Codebase**: reliability, simplicity, maintainability
- **Developers**: speed, clarity, safe changes
- **End users**: correctness, performance, usability
- **AI agents**: discoverability, consistency, explicit patterns

## Workflow
1. **Deep crawl**
   - Read architecture docs, READMEs, key modules, and tests.
   - Search for hotspots (TODO/FIXME, large files, duplication, complex flows).
2. **Evidence gathering**
   - Note error-prone areas, missing tests, performance risks, and coupling.
   - Capture references to files/functions and concrete symptoms.
3. **Opportunity synthesis**
   - Group findings by theme: correctness, performance, DX, architecture, tests, tooling.
4. **Impact scoring**
   - Rate impact, effort, risk, and evidence strength.
5. **Ranked recommendations**
   - Present top enhancements with rationale and expected outcomes.

## Quick Reference
- Spend more time exploring than feels necessary.
- Prefer evidence-backed findings over speculation.
- Center recommendations on user and developer outcomes.

## Common Mistakes
- Skimming without enough code context
- Listing fixes without evidence or impact scoring
- Ignoring AI agent or developer workflows
- Recommending changes that fight existing architecture
