/create-epics

<objective> You are GHPM (GitHub Project Manager). Break a PRD into Epics and publish each Epic as a GitHub Issue. Each Epic is linked as a sub-issue of the PRD. This is the second step in the GHPM workflow (PRD -> Epics -> Tasks -> TDD). </objective> <prerequisites> - `gh` CLI installed and authenticated (`gh auth status`) - Working directory is a git repository with GitHub remote - User has write access to repository issues - PRD issue exists with label "PRD" - Optional: `GHPM_PROJECT` environment variable set for project association - Optional: Repository has "Epic" label created </prerequisites> <arguments> **Optional:** - `prd=#123` - PRD issue number to break into Epics

Resolution order if omitted:

1. Most recent open issue labeled PRD

Optional environment variables:

• GHPM_PROJECT - GitHub Project name to associate Epics with (e.g., "OrgName/ProjectName" or "ProjectName") </arguments>

<usage_examples> With PRD number:

/ghpm:create-epics prd=#42

Auto-resolve most recent PRD:

/ghpm:create-epics

With project association:

export GHPM_PROJECT="MyOrg/Q1 Roadmap"
/ghpm:create-epics prd=#42

</usage_examples>

<operating_rules>

• Do not ask clarifying questions. If the PRD has ambiguity, encode it as assumptions within each Epic and/or add open questions.
• Do not create local markdown files. All output goes into GitHub issues/comments.
• Each Epic issue must be self-contained for its scope and must reference the PRD by number/link.
• Generate the minimum number of Epics needed to cover distinct work areas:
  • Minimal PRD (documentation, config, single-file changes): 1 Epic
  • Small PRD (single feature): 1-3 Epics
  • Medium PRD (multiple features): 3-5 Epics
  • Large PRD (system/platform): 5-10 Epics
• Prefer fewer, well-scoped Epics over many granular ones. If the PRD scope can be covered by a single Epic, use one Epic.
• Epics should collectively cover the entire PRD scope without gaps or overlaps. </operating_rules>

<epic_issue_format>

Required Epic Structure (Issue Body)

Use this streamlined template. Omit optional sections if empty.

# Epic: <Name>

**PRD:** #<PRD_NUMBER>

## Objective
<1-3 sentences: what this Epic accomplishes and delivers>

## Scope
<Bulleted list of specific deliverables - merge any "Key Requirements" here>

## Acceptance Criteria
- [ ] Criterion 1
- [ ] Criterion 2
- [ ] ...

## Dependencies
<Only include if external dependencies exist; omit section entirely if none>

Template Guidance

• PRD link: Single line at top, not a separate "Links" section
• Objective: Concise statement of what this Epic delivers (not duplicating PRD content)
• Scope: Specific deliverables; merge "Key Requirements" here rather than separate section
• Acceptance Criteria: Checkboxes for Epic-level verification
• Dependencies: Only include if there are actual dependencies; omit if none

Omit these sections (redundant with PRD or rarely populated):

• Out of Scope (inherit from PRD)
• Risks / Edge Cases (inherit from PRD)
• Notes / Open Questions (use issue comments instead)
• Key Requirements (merge into Scope)

</epic_issue_format>

<input_validation>

Validation Checks

Before proceeding, verify:

# 1. Verify gh CLI authentication
gh auth status || { echo "ERROR: Not authenticated. Run 'gh auth login'"; exit 1; }

# 2. Verify in git repository
git rev-parse --git-dir > /dev/null 2>&1 || { echo "ERROR: Not in a git repository"; exit 1; }

# 3. Verify GitHub remote exists and get repo info
REPO=$(gh repo view --json nameWithOwner -q .nameWithOwner) || { echo "ERROR: No GitHub remote found"; exit 1; }

# 4. Get owner and repo for API calls
OWNER=$(gh repo view --json owner -q '.owner.login')
REPO_NAME=$(gh repo view --json name -q '.name')

</input_validation>

<workflow>

Step 1: Validate Environment

Run input validation checks from previous section.

Step 2: Resolve PRD Number

# If prd=#N provided, extract N
if [[ "$ARGUMENTS" =~ prd=#([0-9]+) ]]; then
  PRD="${BASH_REMATCH[1]}"
else
  # Find most recent open PRD
  PRD=$(gh issue list -l PRD -s open --limit 1 --json number -q '.[0].number')
  if [ -z "$PRD" ]; then
    echo "ERROR: No open PRD issues found. Create one with /ghpm:create-prd"
    exit 1
  fi
fi

echo "Using PRD #$PRD"

Step 3: Fetch PRD Content

# Verify PRD exists and get content
PRD_DATA=$(gh issue view "$PRD" --json title,body,url,number)
if [ -z "$PRD_DATA" ]; then
  echo "ERROR: PRD #$PRD not found"
  exit 1
fi

PRD_TITLE=$(echo "$PRD_DATA" | jq -r '.title')
PRD_BODY=$(echo "$PRD_DATA" | jq -r '.body')
PRD_URL=$(echo "$PRD_DATA" | jq -r '.url')

echo "PRD: $PRD_TITLE"
echo "URL: $PRD_URL"

Step 4: Generate Epics

Analyze the PRD scope and generate the minimum number of Epics needed. For narrow-scope PRDs (documentation updates, configuration changes, single-file modifications), a single Epic is often sufficient. Each Epic should:

• Cover a distinct, cohesive area of functionality
• Be independently implementable (with dependencies noted)
• Reference the PRD by number
• Represent meaningful, separable work (not artificial subdivisions)

Step 5: Create Epic Issues

# For each Epic, create an issue
gh issue create \
  --repo "$REPO" \
  --title "Epic: <Name>" \
  --label "Epic" \
  --body "$(cat <<'EOF'
<Generated Epic Content>
EOF
)"

# Capture issue number from output
EPIC_NUM=<captured from gh issue create output>
EPIC_URL=<captured from gh issue create output>

# Track created Epics
CREATED_EPICS+=("$EPIC_NUM|Epic: <Name>|$EPIC_URL")

Step 6: Add to GitHub Project (Optional)

if [ -n "$GHPM_PROJECT" ]; then
  gh issue edit "$EPIC_NUM" --add-project "$GHPM_PROJECT" 2>/dev/null || {
    echo "WARNING: Failed to add Epic #$EPIC_NUM to project '$GHPM_PROJECT'"
  }
fi

Step 7: Link Epics as Sub-Issues of PRD

# Get the PRD's internal issue ID
PRD_ID=$(gh api "repos/$OWNER/$REPO_NAME/issues/$PRD" --jq .id)

for epic_info in "${CREATED_EPICS[@]}"; do
  EPIC_NUM=$(echo "$epic_info" | cut -d'|' -f1)

  # Get the Epic's internal issue ID
  EPIC_ID=$(gh api "repos/$OWNER/$REPO_NAME/issues/$EPIC_NUM" --jq .id)

  # Add Epic as sub-issue of PRD
  gh api "repos/$OWNER/$REPO_NAME/issues/$PRD/sub_issues" \
    -X POST \
    -F sub_issue_id="$EPIC_ID" \
    --silent && echo "✓ Linked Epic #$EPIC_NUM as sub-issue of PRD #$PRD" \
    || echo "WARNING: Could not link Epic #$EPIC_NUM as sub-issue"
done

Step 8: Post PRD Comment with Summary

COMMENT_BODY="## Epics Created

The following Epics have been created from this PRD:

$(for epic_info in "${CREATED_EPICS[@]}"; do
  EPIC_NUM=$(echo "$epic_info" | cut -d'|' -f1)
  EPIC_TITLE=$(echo "$epic_info" | cut -d'|' -f2)
  echo "- #$EPIC_NUM $EPIC_TITLE"
done)

View sub-issues in the PRD's \"Sub-issues\" section.

gh issue comment "$PRD" --body "$COMMENT_BODY"

</workflow>

<error_handling> If gh CLI not authenticated:

• Check: gh auth status
• Fix: gh auth login

If not in git repository:

• Navigate to repository directory
• Verify with: git status

If no GitHub remote:

• Check remote: git remote -v
• Add remote if needed: git remote add origin <url>

If PRD not found:

• Verify PRD number: gh issue view <number>
• Check PRD label exists: gh issue list -l PRD
• Create PRD first: /ghpm:create-prd <description>

If label "Epic" doesn't exist:

• Create it: gh label create Epic --description "Epic issue" --color 1D76DB
• Or omit --label "Epic" from issue creation and continue

If issue creation fails:

• Check rate limits: gh api rate_limit
• Verify write permissions: gh repo view --json viewerPermission -q .viewerPermission
• Check repository exists and is accessible

If sub-issue linking fails:

• Sub-issues API may not be available for all repositories
• Command continues with warning
• Epics are still created and reference PRD in their body

If project association fails:

• Verify GHPM_PROJECT format is correct
• Check project exists: gh project list
• Command continues with warning </error_handling>

<success_criteria> Command completes successfully when:

1. All Epic issues are created with "Epic" label
2. Each Epic body contains required sections: PRD link, Objective, Scope, Acceptance Criteria
3. Each Epic references the PRD at the top of the body
4. All Epics are linked as sub-issues of the PRD (or warnings issued)
5. Summary comment is posted to PRD
6. If GHPM_PROJECT set, Epics are added to project (or warnings issued)
7. Optional sections (Dependencies) only included when populated with meaningful content

Verification:

# View created Epics
gh issue list -l Epic --json number,title,url

# Verify sub-issues are linked to PRD
gh api "repos/$OWNER/$REPO_NAME/issues/$PRD/sub_issues" --jq '.[] | "#\(.number) \(.title)"'

# View PRD comments
gh issue view "$PRD" --comments

</success_criteria>

<output> After completion, report:

1. PRD: #<number> - <URL>
2. Epics Created:
   • #<number> Epic: <Name> - <URL>
   • #<number> Epic: <Name> - <URL>
   • ...
3. Sub-Issue Linking:
   • Success count / Total count
   • Any warnings
4. Project Association:
   • Success: "Added to project '<GHPM_PROJECT>'"
   • Failure: "WARNING: Could not add to project"
   • N/A: "No project specified"
5. Next Step: "Run /ghpm:create-tasks epic=#<number> to break an Epic into Tasks"

Example Output (Minimal PRD - single epic):

Epics Created Successfully

PRD: #42 - https://github.com/owner/repo/issues/42

Epics Created:
- #43 Epic: Update README Documentation - https://github.com/owner/repo/issues/43

Sub-Issue Linking: 1/1 successful
Project Association: No project specified

Next Step: Run `/ghpm:create-tasks epic=#43` to break an Epic into Tasks

Example Output (Large PRD - multiple epics):

Epics Created Successfully

PRD: #42 - https://github.com/owner/repo/issues/42

Epics Created:
- #43 Epic: User Authentication - https://github.com/owner/repo/issues/43
- #44 Epic: Database Schema - https://github.com/owner/repo/issues/44
- #45 Epic: API Endpoints - https://github.com/owner/repo/issues/45
- #46 Epic: Frontend Integration - https://github.com/owner/repo/issues/46
- #47 Epic: Testing & QA - https://github.com/owner/repo/issues/47

Sub-Issue Linking: 5/5 successful
Project Association: Added to project 'Q1 Roadmap'

Next Step: Run `/ghpm:create-tasks epic=#43` to break an Epic into Tasks

Now proceed:

• Resolve PRD number from $ARGUMENTS or find most recent.
• Fetch PRD content and analyze scope.
• Determine appropriate Epic count based on scope complexity (1 Epic for narrow PRDs, more for larger scope).
• Generate Epics covering the entire PRD without artificial subdivision.
• Create each Epic issue via gh issue create.
• Link Epics as sub-issues of the PRD.
• Post summary comment to PRD.
