Complete Work on a GitHub Issue

Finalize work on an issue by closing it, updating project status, and ensuring all artifacts are properly maintained.

Input

$ARGUMENTS should contain the issue number (e.g., "42" or "#42").

If no issue number provided, use AskUserQuestion to ask which issue to complete.

Help

If $ARGUMENTS contains --help or -h, display the following and stop — do not execute the workflow.

/complete-task [#N]

  Complete work on a GitHub issue — close issue, update project, prompt for doc updates.

Arguments:
  #N              Issue number (e.g., 42 or #42)
  --help, -h      Show this help

What it does:
  1. Verifies issue state and checks PR/branch status
  2. Closes the issue
  3. Updates project status to Done
  4. Handles design doc (keep / move to archive)
  5. Suggests overview doc updates and ADR creation
  6. Offers branch cleanup

Examples:
  /complete-task #42
  /complete-task 36

Workflow

1. Verify Issue State

Use mcp__GitHub__get_issue with:

• owner: "log2n-io"
• repo: "Typhon"
• issue_number: <number>

Confirm the issue is currently open and has been worked on.

2. Check PR and Branch State

Step 2a: Check for existing PRs (open or merged):

Use mcp__GitHub__search_issues with:

• q: "repo:log2n-io/Typhon type:pr <number>"

This returns PRs that mention the issue number.

Step 2b: Detect unmerged feature branch (if no merged PR found):

# Find the feature/fix branch for this issue
git branch --list "feature/<number>*" --list "fix/<number>*"

# If a branch exists, check if it has commits ahead of main
git rev-list --count main..<branch_name>

Decision matrix:

PR State	Branch State	Action
Merged PR exists	—	Proceed normally (happy path)
Open PR exists	—	Warn: "PR should be merged first" -> ask to proceed or wait
No PR	Branch has commits ahead of main	Warn: "Branch has N unmerged commits" -> offer to create PR
No PR	No feature branch / branch is even with main	Proceed normally (work may have been committed directly to main)

If no PR and branch has unmerged commits, ask:

Question: "Branch '<branch_name>' has N commits not yet merged to main. A PR should typically be created and merged before completing the task. What would you like to do?"
Header: "PR"
Options:
  - Create a PR now (Recommended) (description: "I'll create a PR from <branch_name> to main, then continue after it's merged")
  - Skip PR (description: "Proceed without a PR — I'll handle merging manually")
  - Cancel (description: "Stop — I'll create and merge the PR first, then re-run /complete-task")

If "Create a PR now":

• Push the branch if not already pushed: git push -u origin <branch_name>
• Create the PR:

Use mcp__GitHub__create_pull_request with:

• owner: "log2n-io"

• repo: "Typhon"

• title: "<summary derived from issue title>"

• body: "<summary derived from issue body>"

• head: "<branch_name>"

• base: "main"

• Then check the claude/ documentation repo for a matching branch with changes:

cd claude
# Check if a matching branch exists and has commits ahead of main
CLAUDE_BRANCH=$(git branch --list "<branch_name>" --format="%(refname:short)")
if [ -n "$CLAUDE_BRANCH" ]; then
  CLAUDE_AHEAD=$(git rev-list --count main.."$CLAUDE_BRANCH")
  echo "claude/ branch: $CLAUDE_BRANCH, commits ahead: $CLAUDE_AHEAD"
else
  echo "claude/ has no matching branch"
fi
cd ..

If the claude/ repo has a matching branch with commits ahead of main, also create a PR for it:

• Push the branch: cd claude && git push -u origin <branch_name> && cd ..
• Create the PR:

Use mcp__GitHub__create_pull_request with:

• owner: "log2n-io"
• repo: "Typhon-docs" (or the actual claude/ remote repo name — check with cd claude && git remote get-url origin && cd ..)
• title: "Docs: <same summary as main PR>"
• body: "Documentation updates for log2n-io/Typhon#<issue_number>"
• head: "<branch_name>"
• base: "main"

Report both PR URLs.

• Stop here — report the PR URL(s) and tell the user to merge them, then re-run /complete-task
• Do NOT proceed to close the issue or update status yet

If "Skip PR":

• Proceed with the rest of the workflow (close issue, update status, etc.)

If "Cancel":

• Stop and report that no changes were made

3. Close the Issue

Use mcp__GitHub__update_issue with:

• owner: "log2n-io"
• repo: "Typhon"
• issue_number: <number>
• state: "closed"

4. Update Project Status to Done

Project item lookup: Read .claude/skills/_helpers.md Section 2 for the robust patterns.

# Step 1: Find the item ID by piping directly to Python (no temp files)
gh project item-list 1 --owner Log2n-io --limit 200 --format json 2>&1 | python3 -c "
import json, sys
items = json.load(sys.stdin)['items']
for item in items:
    if item.get('content', {}).get('number') == int(sys.argv[1]):
        print(item['id'])
        sys.exit(0)
print('NOT_FOUND')
" <issue_number>

# Step 2: Update status to Done (using the item ID from step 1)
gh project item-edit --project-id PVT_kwDOEcGj5M4Bb-8P --id <item_id> \
  --field-id PVTSSF_lADOEcGj5M4Bb-8PzhWrH1A \
  --single-select-option-id 98236657  # "Done"

5. Check for Design Doc

Look for design doc in:

• Issue body (links to claude/design/)
• Project item's "Design Doc" field

If a design doc exists, ask the user:

Question: "The design doc 'claude/design/FeatureName.md' was used. What should happen to it?"
Header: "Design Doc"
Options:
  - Keep in design/ (Recommended) — still the authoritative spec; stays as living documentation for the feature
  - Move to archive/ — outdated, superseded, or no longer relevant

Note: we no longer move shipped design docs to reference/ — design docs are the feature's living spec and stay in design/ after implementation. Archive is reserved for superseded designs.

6. Suggest Overview Updates

Check if this issue might affect overview documentation:

Suggest potentially affected overview docs based on Area field:

• Database -> claude/overview/02-execution.md, claude/overview/04-data.md
• Transactions -> claude/overview/02-execution.md
• MVCC -> claude/overview/04-data.md
• Indexes -> claude/overview/04-data.md
• Schema -> claude/overview/04-data.md
• Storage -> claude/overview/03-storage.md
• Memory -> claude/overview/08-resources.md
• Concurrency -> claude/overview/01-concurrency.md
• Primitives -> claude/overview/11-utilities.md
• Telemetry -> claude/overview/09-observability.md

Ask:

Question: "These overview docs might need updates based on this work:"
  - claude/overview/XX-topic.md

"Would you like to review any of them?"
Options:
  - Yes, open them for review
  - Skip for now

7. Check for ADR Need

Ask:

Question: "Did this work involve a significant architectural decision that should be documented?"
Header: "ADR"
Options:
  - Yes, create an ADR (I'll help draft it)
  - No, no significant decisions

If yes, help create an ADR in claude/adr/ following the template.

8. Clean Up Branch (Optional)

Check if a local feature/fix branch still exists for this issue:

git branch --list "feature/<number>*" --list "fix/<number>*"

If a branch exists and a merged PR was found in step 2 (meaning the code is safely on main):

Question: "Branch '<branch_name>' was merged via PR. Delete the local branch?"
Header: "Branch"
Options:
  - Yes, delete it (description: "git branch -d <branch_name>")
  - Keep it (description: "Leave the branch for now")

If "Yes":

• git branch -d <branch_name>
• Also clean up the claude/ repo branch if it exists:

  cd claude && git checkout main && git branch -d <branch_name> 2>/dev/null; cd ..
  

If no merged PR was found (user chose "Skip PR" in step 2), do not offer to delete — the branch may contain the only copy of the work.

9. Report Summary

Completing #<number>: <title>

  Issue closed
  Status: In Progress -> Done
  Design doc: claude/design/<Name>.md
   -> Kept (or archived)

  Overview docs reviewed: (list or "skipped")
