## About

## What this skill does

Reads a raw `git diff` or unified diff text and returns a structured breakdown of
what changed. Identifies the affected files, counts added and removed lines per file,
writes a human-readable English summary of the change intent, and suggests a
conventional commit message (`feat:`, `fix:`, `chore:`, `refactor:`, `docs:`) based
on the change type detected.

## Inputs

- `diff_text` — raw output of `git diff`, `git diff HEAD`, or a `.patch` file content
- `context` — optional string describing the purpose of the change (improves commit message quality)

## Outputs

- `files_changed` — list of `{path, additions, deletions, change_type}` objects
- `lines_added` — total lines added across all files
- `lines_removed` — total lines removed across all files
- `summary` — 2–3 sentence plain-English description of what the diff does
- `commit_message` — suggested conventional commit message, e.g. `fix: correct token expiry check in auth middleware`

## Example

```bash
git diff HEAD | asf query "summarize this diff and suggest a commit message"
```

Output:
```json
{
  "files_changed": [
    {"path": "src/auth.js", "additions": 4, "deletions": 2, "change_type": "modified"}
  ],
  "lines_added": 4,
  "lines_removed": 2,
  "summary": "Fixed token expiry comparison using strict inequality. Updated unit test to cover the edge case.",
  "commit_message": "fix: use strict inequality for token expiry check in auth middleware"
}
```
