# tool-git-delta

## When To Use

- Improve readability of git patch review in terminal.
- Present staged and unstaged diffs with syntax awareness.
- Configure git pager output for ongoing review workflows.

## Trusted Commands

```bash
git config --global core.pager delta
git config --global interactive.diffFilter 'delta --color-only'
git diff
git diff --staged
git show HEAD
```

## Safe Defaults

- Keep plain git fallback available for non-interactive logs.
- Review both staged and unstaged diffs before commit.
- Prefer local overrides before changing global defaults in shared environments.

## Common Pitfalls

- Package name may be `git-delta` while binary is `delta`.
- Without core pager config, delta is not used automatically.
- Styled output is for review, not machine parsing.

## Output Interpretation

- Diff semantics are still git patch semantics with enhanced rendering.
- Side-by-side and line-number rendering help review speed.

## Why It Matters For Agents

- Makes code review output significantly easier to summarize and verify.
- Improves human confidence in patch intent before merge.

## Repo Conventions

- Use delta to improve review quality, not to replace tests.
- Preserve focused commits with minimal unrelated changes.

## Trigger Examples

- Should trigger: "Show me a readable diff of staged changes."
- Should trigger: "Review this patch visually before commit."
- Should not trigger: "Install missing Python dependencies."
