Post Ticket Summary

Add a structured implementation summary comment to a Linear issue after completing work.

Preferences

_Read ~/.claude/skills/post-ticket-summary/preferences.md using the Read tool. If not found, no preferences are set._

Context

_On startup, use Bash to detect: current git branch, recent commits (git log --oneline -20), and repo name (gh repo view --json nameWithOwner -q .nameWithOwner). Skip any that fail._

Command routing

Check $ARGUMENTS:

• `help` → display help then stop
• `config` → interactive setup then stop
• `reset` → delete ~/.claude/skills/post-ticket-summary/preferences.md, confirm, stop
• `--preview <issue-id>` → show comment without posting then stop
• `--minimal <issue-id>` → use minimal template
• anything else → post summary

Post Summary — Document implementation on a Linear issue

Usage:
  /post-ticket-summary <issue-id>               Post full summary
  /post-ticket-summary --preview <issue-id>     Show without posting
  /post-ticket-summary --minimal <issue-id>     Short summary (skip architecture/reuse)
  /post-ticket-summary config                   Set template preferences
  /post-ticket-summary reset                    Clear preferences
  /post-ticket-summary help                     This help

Examples:
  /post-ticket-summary AIS-810
  /post-ticket-summary --preview AIS-810
  /post-ticket-summary --minimal AIS-810

What it does:
  1. Reads the Linear issue and codebase
  2. Analyzes recent commits and changed files
  3. Builds structured summary comment
  4. Posts to the Linear issue

Config

Use `AskUserQuestion`:

Q1 — "Default template?" (full (default), minimal) Q2 — "Which sections to include?" (multiSelect: true)

• Implementation summary
• Key decisions / architecture
• What was reused
• How to test
• Notes

Q3 — "Auto-detect issue from branch?" (Yes (default), No — always ask)

Save to ~/.claude/skills/post-ticket-summary/preferences.md.

First-time detection

If no preferences file exists, show: "First time using /post-ticket-summary? Run /post-ticket-summary config to customize template sections, or continue with full template."

Then proceed.

Steps

1. Resolve issue

• If issue ID provided in $ARGUMENTS, use it
• If no ID and auto-detect is on, extract from branch name (pattern: user/ais-NNN-*)
• If still no ID, ask via AskUserQuestion

Fetch the issue: title, description, project, status.

2. Check for existing summary

Fetch comments on the issue. If an implementation summary comment already exists, ask: "An implementation summary already exists. Replace it, or skip?"

3. Gather implementation details

From the codebase:

• Recent commits on current branch (pre-injected)
• Key files changed: git diff main...HEAD --stat (or appropriate base)
• Read the main changed files to understand what was built

From project context:

• CLAUDE.md for conventions
• README.md for project overview

Ask user (optional — use AskUserQuestion with all optional):

• Loom URL or recording link (or placeholder)
• Live/staging URL for testing
• Any additional context worth documenting

If user says "skip", use placeholders.

4. Build comment

Full template:

## Implementation Summary

{1-2 paragraphs: what was built and the product goal. Focus on business value.}

### What Was Reused

| Component | Source | Adaptation |
|-----------|--------|------------|
| {component} | {origin} | {what changed} |

---

## How to Test

**Branch:** `{branch}`
**Live URL:** {url or N/A}

### Steps
1. {step}
2. {step}
3. {step}

---

## Features

### 1. {Feature Name}

{2-3 sentences from user perspective. What they see, what they can do, business value.}

### 2. {Feature Name}

{Same structure}

---

## Key Decisions

| Decision | Rationale |
|----------|-----------|
| {decision} | {why} |

---

## Notes

- {Additional context}

Minimal template:

## Implementation Summary

{1-2 paragraphs}

## How to Test

**Branch:** `{branch}`

1. {step}
2. {step}

## Notes

- {anything important}

Apply section toggles from preferences.

Content guidelines

• Summary: Lead with the problem, then what the implementation does.
• Features: User perspective — what they see and do. No file paths.
• Key Decisions: Focus on the "why" behind non-obvious choices.
• Reuse: Show what was leveraged vs built new.

5. Post or preview

If --preview: display the comment and stop.

Otherwise: post via create_comment.

6. Report

Posted implementation summary to {issue-id}.

Sections: {list of included sections}

Next steps:
  1. Record Loom and update the link
  2. Add screenshots if relevant
  3. Replace any [PLACEHOLDER] markers

7. Learn

If user removes sections consistently, update preferences. If user adds custom sections, note the pattern.
