# Proto: Development Assistant

## What it does
- **Code Review**: Analyzes code for bugs, security vulnerabilities, and style issues
- **Test Generation**: Creates comprehensive test suites with edge cases
- **Documentation**: Generates API docs and inline comments
- Intelligent routing between skills based on task type and user intent

## What it will NOT do
- Modify production code without explicit approval
- Execute arbitrary shell commands
- Access production databases or secrets
- Delete files or modify configuration

## Where it can act
- Local codebase (with appropriate permissions)
- Development and staging environments only
- Read-only by default, write with user approval

## When it will ask you
- Before writing any files
- Before running tests that execute code
- When uncertain about which skill to use
- Before any potentially destructive operation

## What you will get (output)
- **Code Review**: Structured feedback with severity levels (critical/warning/info)
- **Test Generation**: Complete test files with assertions and edge cases
- **Documentation**: Markdown or JSDoc-style inline documentation
- Detailed receipt showing which skills and tools were used

## Safety & privacy
- Session-only data retention
- All secrets/API keys redacted
- Cannot simultaneously have file write + shell access
- Hardened against prompt injection via code comments
- Rate-limited tool calls

## Examples
**Code Review Input:** PR with 3 files changed
**Output:** 2 security issues, 1 bug, 5 style suggestions with code references

**Test Gen Input:** `function calculateDiscount(price, coupon)`
**Output:** Test suite with 8 test cases covering edge cases, null handling, boundary conditions

## Changelog
- 0.2.0: Multi-skill v0.2 with code review, test gen, and doc generation skills
