Epic Executor

Execute an epic by running the spec workflow on each task in dependency order, with adversarial checkpoints between tasks.

Phase 1: Load Epic

1. Identify the epic: Parse $ARGUMENTS for epic name or issue number
2. Fetch issues: Use gh issue list to get all tasks for this epic:

   gh issue list --milestone "<epic-milestone>" --state open --json number,title,body,labels --limit 50
   

3. Parse dependencies: Read each issue body for "Blocked by: #N" references
4. Build execution order: Topological sort respecting dependencies
5. Show plan: Present the execution order to the user for confirmation

Phase 2: Execute Tasks

For each task in execution order:

2a. Start Task

• Update GitHub issue: gh issue edit <number> --remove-label "status:planned" --add-label "status:in-progress"
• Read the full issue body for acceptance criteria and approach
• If omega memory is available, call omega_query() for context on related past work

2b. Run Spec Workflow

• Create a spec from the issue: write spec JSON with issue details
• Plan: If the issue body has a clear approach, use /next-level:quick. Otherwise, Read skills/spec/references/spec-plan.md and follow the process.
• Implement: Read skills/spec/references/spec-implement.md and follow the process with strict TDD.
• Verify: Read skills/spec/references/spec-verify.md and follow the process — tests, lint, code review.

2c. Adversarial Checkpoint

After each task completes, dispatch the checkpoint-reviewer agent:

• Pass: project plan, completed task details, test results, diff since epic started
• The reviewer verifies: task matches plan, no drift from vision, integration with previous tasks works

Trust Escalation

Review depth adjusts based on task position and track record:

• First 3 tasks: Full review (code + tests + integration check)
• Middle tasks: Medium review (tests pass + integration check)
• Final tasks: Light review (tests pass, no regressions)

The reviewer returns one of: CONTINUE (proceed to next task), FLAG_FOR_HUMAN, or STOP.

If the reviewer returns a non-CONTINUE verdict:

• FLAG_FOR_HUMAN: Pause and present findings to the user
• STOP: Halt execution, report the issue

2d. Complete Task

• Update and close GitHub issue: gh issue edit <number> --remove-label "status:in-progress" --add-label "status:complete" then gh issue close <number>
• Commit with message referencing the issue: fixes #<number>
• If omega memory available: omega_store(task_summary, "milestone")
• Call omega_checkpoint() if context approaches 85% to ensure session continuity

Phase 3: Multi-Epic Coordination

When a project has multiple epics:

• Respect epic-level dependencies (don't start Epic 3 if Epic 2 isn't done)
• Track cross-epic integration points
• After completing an epic, update the GitHub milestone:

  gh api repos/{owner}/{repo}/milestones/<number> -X PATCH -f state="closed"
  

Independent epics CAN run in parallel via agent teams (see /next-level:team-execute).

Phase 4: Session Continuity

If context approaches 85% during execution:

1. Call omega_checkpoint() to save full state
2. Write resume prompt to ~/.next-level/sessions/{id}/resume.md:
   • Project context and epic being executed
   • Completed tasks (with issue numbers)
   • Current task (in progress or next)
   • Key decisions made during execution
3. Tell the user to run /next-level:resume in a new session

Error Handling

• If a task fails verification after 3 attempts: mark it as blocked, skip to next unblocked task, flag for human
• If a dependency is unresolvable: pause and ask the user
• If gh commands fail: fall back to local tracking via spec JSON files
• If omega is unavailable: use local state files for continuity

Output

After completing all tasks in the epic:

EPIC COMPLETE: <epic-name>
═════════════════════════
Tasks completed: N/M
Tests passing: all
Issues closed: #1, #2, #3, ...
Milestone: closed

Next: /next-level:execute <next-epic> (if applicable)
