Planning Workflow

Every unit of work gets a GitHub issue. One session = one issue = one PR.

---

When to Create an Issue

Situation	Action
Starting new work	Create issue first
"Let's plan X"	Create detailed issue
Scope creep mid-session	Pause → ask about new issue
Quick fix / trivial change	Ask if issue needed

---

Session Flow

Planning Phase (plan mode active)

1. Understand the work
2. Draft issue content (do NOT create yet)
3. Include issue draft in plan file
4. Exit plan mode for approval

Execution Phase (after plan approval)

5. Create the issue (first step after approval)
6. Track issue as session context
7. Do the work (core-workflow)
8. If scope expands → STOP, ask about new issue
9. Finalize → PR closes the issue

---

Creating the Issue

Plan Mode: During planning, draft the issue content and include it in your plan file. Do NOT run gh issue create until after plan approval.

Before Creating

Gather all context needed to do the work:

• What problem are we solving?
• What's the approach?
• What are the acceptance criteria?
• What files/areas will be touched?
• Any risks or open questions?

Issue Format

gh issue create \
  --repo <org>/<repo> \
  --title "Brief description" \
  --body "## Summary
What we're doing and why.

## Approach
How we'll implement this.
- Step 1
- Step 2
- Step 3

## Acceptance Criteria
- [ ] Criterion 1
- [ ] Criterion 2
- [ ] Tests written

## Files/Areas
- \`path/to/file.ts\`
- \`path/to/other.php\`

## Notes
Any additional context, decisions, risks."

In plan mode: Include this draft in your plan file and exit plan mode. After approval: Run gh issue create as the first execution step.

After Creating

1. Note the issue number
2. Set issue type if applicable (Task or Bug)
3. Add to project board (if not auto-added)
4. Move to "In Progress"
5. Store internally: "Working on #N - [title]"

---

Session Context Tracking

Once an issue is created, track it as session context:

Active Issue: #123 - Feature description
Repo: <org>/<repo>

This context should be referenced:

• When making implementation decisions
• When scope questions arise
• When creating the PR

If context compaction occurs, the issue contains the full context. Fetch it:

gh issue view <number> --repo <org>/<repo>

---

Planning Multiple Issues

Sometimes planning reveals work that should be split into multiple issues.

When to Split

• Distinct deliverables that could merge independently
• Different areas of the codebase with no dependencies
• Work that benefits from separate review cycles

How to Handle

1. Draft all issues in the plan file
2. Note dependencies/order if any
3. Get approval on the full set
4. After approval: create all issues, pick one to start
5. Other issues become backlog (or parallel work if independent)

Plan File Format

## Issue Drafts

### Issue 1: Feature A

Summary, approach, acceptance criteria...

### Issue 2: Feature B

Summary, approach, acceptance criteria...

## Execution Order

1. Start with Issue 1 (no dependencies)
2. Issue 2 depends on Issue 1

---

Scope Creep Handling

When additional work is discovered mid-session:

1. STOP — Don't just do it

2. Assess — Is this part of the current issue or separate?

3. Ask:

   I've discovered we also need to [X]. This seems outside the scope of #123.
   
   Options:
   1. Add to current issue (if small and related)
   2. Create new issue for separate work
   3. Note it and skip for now
   
   How do you want to handle this?
   

4. If new issue: Create it, but don't work on it this session

5. If adding to current: Update the issue body with new scope

Updating Current Issue

# View current body
gh issue view <number> --repo <org>/<repo>

# Edit to add scope (opens editor)
gh issue edit <number> --repo <org>/<repo>

---

Finalization

When work is complete and approved for commit:

1. Create PR with Issue Reference

PR_URL=$(gh pr create \
  --draft \
  --repo <org>/<repo> \
  --title "feat: clear description" \
  --body "## Summary
What was done.

## Changes
- Change 1
- Change 2

## Testing
- [ ] Tests pass
- [ ] Manual testing done

Closes #<issue-number>")

printf '%s' "$PR_URL" | pbcopy   # draft PR URL copied to clipboard, ready to paste
echo "$PR_URL"

2. PR Summary Format

When presenting the PR:

PR ready to create:

Title: feat: add feature description

Body:
## Summary
Implemented the feature.

## Changes
- Added endpoint
- Added validation
- Added tests

Closes #123

The Closes #123 automatically:

• Links the PR to the issue
• Moves issue to "Done" when PR merges

Quick Reference

Action	Command
Create issue	gh issue create --repo <org>/<repo> ...
View issue	gh issue view <num> --repo <org>/<repo>

Don't

• Start work without an issue
• Create issue during plan mode (draft only, create after approval)
• Expand scope without asking
• Create PR without Closes #N
• Work on multiple issues in one session
• Forget to track the active issue
• Amend commits unless explicitly told to
