GitHub Plan Adapter

Sync a plan file to GitHub Issues (and optionally a GitHub Project). This skill is invoked as a sub-agent by /plan — it is not user-invocable directly.

Prerequisites

•gh CLI authenticated (gh auth status succeeds)
•Current directory is a git repo with a GitHub remote
•Plan file exists at the path provided in the prompt

Inputs (provided in sub-agent prompt)

•PLAN_FILE: absolute path to the plan file (epic for complex, single file for simple)
•PROJECT_NUMBER (optional): GitHub Project number to add issues to

For complex plans, a sibling directory with the same name (minus .md) contains detailed task files:

code

.claude/plans/2fa-authentication.md        ← PLAN_FILE (epic)
.claude/plans/2fa-authentication/           ← task directory
    01-okta-sdk-setup.md
    02-keychain-service.md
    ...

Workflow

1. Parse the plan file

Read the plan file. Extract from frontmatter:

•feature — used as the epic issue title
•type — simple or complex

2. Determine repo

bash

gh repo view --json nameWithOwner -q '.nameWithOwner'

3. Ensure labels exist

bash

gh label create epic --description "Parent issue tracking a feature" --color "3B82F6" 2>/dev/null || true
gh label create task --description "Implementation task from a plan" --color "10B981" 2>/dev/null || true

4. Create the epic issue

Build the epic issue body from the plan file content.

bash

gh issue create --title "<feature>" --body "<plan body>" --label "epic"

Store the returned issue number as EPIC_NUMBER.

Get the epic's node ID (needed for the sub-issue API):

bash

EPIC_NODE_ID=$(gh issue view $EPIC_NUMBER --json id -q '.id')

5. Create task issues and attach as sub-issues (complex plans only)

Derive the task directory path from PLAN_FILE: strip .md extension.

bash

TASK_DIR="${PLAN_FILE%.md}"
ls "$TASK_DIR"/*.md

Read each task file in order (filenames are NN-slug.md). For each task:

a) Create the issue:

bash

gh issue create \
  --title "<task title from frontmatter>" \
  --body "<full task file content + dependency info>" \
  --label "task"

Include in the body:

•The full task file content (objective, approach, files, acceptance criteria)
•Parent: #<EPIC_NUMBER>
•Depends on: #<issue>, #<issue> (map task numbers from the frontmatter depends_on field to the corresponding created issue numbers)

Store the returned issue number. Get its node ID:

bash

TASK_NODE_ID=$(gh issue view $TASK_NUMBER --json id -q '.id')

b) Attach as a native sub-issue of the epic:

bash

gh api graphql \
  -H "GraphQL-Features: sub_issues" \
  -f query='
    mutation($parentId: ID!, $childId: ID!) {
      addSubIssue(input: { issueId: $parentId, subIssueId: $childId }) {
        subIssue { number title }
      }
    }' \
  -f parentId="$EPIC_NODE_ID" \
  -f childId="$TASK_NODE_ID"

This creates a proper parent-child relationship visible in GitHub's UI (the "Sub-issues" section on the epic), not just a #reference mention.

c) Repeat for all task files, preserving creation order so sub-issues appear in build order.

6. Update the epic body with task links

After all sub-issues are attached, update the epic body to include a reference checklist:

bash

gh issue edit $EPIC_NUMBER --body "<updated body with issue links>"

The checklist serves as a readable summary alongside the native sub-issues panel:

markdown

## Tasks
- [ ] #<issue1> — <task title>
- [ ] #<issue2> — <task title>

7. Add to GitHub Project (optional)

If PROJECT_NUMBER is provided:

bash

# Get project ID
PROJECT_ID=$(gh api graphql -f query='
  query($owner: String!, $number: Int!) {
    user(login: $owner) {
      projectV2(number: $number) { id }
    }
  }' -f owner="$(gh api user -q '.login')" -F number=$PROJECT_NUMBER -q '.data.user.projectV2.id' 2>/dev/null || \
  gh api graphql -f query='
  query($owner: String!, $number: Int!) {
    organization(login: $owner) {
      projectV2(number: $number) { id }
    }
  }' -f owner="$(echo $REPO | cut -d/ -f1)" -F number=$PROJECT_NUMBER -q '.data.organization.projectV2.id')

# Add epic
gh api graphql -f query='
  mutation($project: ID!, $content: ID!) {
    addProjectV2ItemById(input: {projectId: $project, contentId: $content}) {
      item { id }
    }
  }' -f project="$PROJECT_ID" -f content="$(gh issue view $EPIC_NUMBER --json id -q '.id')"

Add each sub-issue to the project as well.

8. Delete the plan file and task directory

Only after all issues are created successfully:

bash

rm "<PLAN_FILE>"
rm -rf "${PLAN_FILE%.md}"   # task directory (complex plans only, if it exists)

If any step failed, do NOT delete anything. Report the error and leave files intact so the user can retry.

9. Report

Output a summary:

•Epic issue: #<number> with link
•Sub-issues created: list with numbers and links
•Project: added to project #<number> (or "no project specified")
•Plan file: deleted (or "retained due to errors")
