PR Summary

This skill generates a structured summary of all changes on the current branch relative to a base branch (default: master).

Workflow

1. Gather branch context

git branch --show-current
git log master..HEAD --oneline
git diff master...HEAD --stat
git log master..HEAD --format="%s%n%b"

If the user supplied a different base branch as an argument, substitute it for master.

Extract the work item number from the branch name (first run of 4+ digits):

2. Analyse the changes

Group changes into logical themes by reading the commit messages and diff stat. Common themes for this project:

• New features — new screens, controls, device integrations, service bus consumers
• Bug fixes — correctness fixes (mention what was wrong and what was corrected)
• Renames / breaking changes — entity or contract renames, API changes
• Service bus / messaging — MassTransit consumers, message contracts, RabbitMQ configuration
• Device integration — RFID, camera, BlackMoth, or other device changes
• UI changes — WPF views, XAML resources, InTruck or Console screens
• Dead code removal — deleted files, unused services, obsolete utilities
• Tooling / config — CLAUDE.md, skills, CI, migrations, feature flags

3. Produce the title and description

Title — one line following the project's PR title format: JTD <work-item> - Brief description

• Use the work item number extracted from the branch name
• Brief description: imperative, ≤ 70 characters total
• Example: JTD 58106 - Handle missing RORO bin weights using tipping records

Output the title first in a code block, then the description below it.

Description — output the entire description inside a single fenced markdown code block (```markdown) so the user can copy-paste it directly into Azure DevOps. Use this structure inside the block:

```markdown
## Description — Work Item #<id>

### <Theme 1 — e.g. "New Feature: Trailer Management Screen">
- Bullet describing the change. Mention affected components (InTruck, Console, ServiceBus, Shared, Devices) where relevant.

### <Theme 2>
- ...

### Bug Fixes
- **<Short label>** — what was wrong and what was changed to fix it.

### Dead Code / Cleanup
- List deleted files or removed abstractions with a one-line rationale.

### Tooling & Config
- Any non-code changes (CLAUDE.md, skills, CI, feature flags).

---
**Files changed:** X  |  **Insertions:** +Y  |  **Deletions:** -Z
```

Rules:

• Use ### headings for each theme; omit sections that have no relevant changes.
• Keep bullets concise — one sentence per item, no padding.
• Always include the Work Item #<id> in the description heading.
• Always include the files/insertions/deletions line at the bottom (read from git diff --stat summary line).
• If the branch has zero commits ahead of master, say so and exit.
• The entire description (everything inside the markdown code block) must not exceed 3500 characters. If the draft exceeds this limit, shorten bullets — summarise groups of related changes into a single bullet, drop minor cleanup items, and abbreviate file lists — until it fits. Never truncate mid-sentence; always produce complete, grammatical bullets.

4. Offer next steps

After the summary, ask if the user wants to:

• Create the PR now (gh pr create) using the summary as the body
• Review the changes first (/code-review)
• Adjust any section of the summary
