Start Work — Atlas Plan Execution

Execute an existing plan via the Atlas task conductor.

Plan: {{arguments}}

Workflow

Step 1: Find the Plan

• If a plan name is specified, look for it in .claude/omo/plans/
• If no name specified, use the most recently modified plan in .claude/omo/plans/
• If no plans exist, tell the user to create one with /plan

Step 2: Check State

Read .claude/omo/boulder.json:

• If active_plan matches this plan AND agent_type == "atlas": resume where we left off
• If active_plan matches this plan AND agent_type != "atlas" (e.g. "briareus"): warn the user that a different agent was previously working on this plan. Show notepad learnings and recent commits. Ask whether to continue with Atlas or cancel.
• If active_plan is set to a DIFFERENT plan: warn the user and ask
• Otherwise: start fresh

Step 3: Update State

Write to .claude/omo/boulder.json:

{
  "active_plan": "plans/{filename}.md",
  "plan_name": "{plan name}",
  "started_at": "{ISO timestamp}",
  "session_ids": [],
  "agent_type": "atlas",
  "failure_count": 0,
  "worktree_path": null
}

Step 4: Launch Atlas

Launch the atlas subagent with:

TASK: Execute the implementation plan at .claude/omo/plans/{filename}.md
EXPECTED OUTCOME: All tasks in the plan completed and verified
REQUIRED TOOLS: Read, Glob, Grep, Bash, TodoWrite
MUST DO: Read the full plan. Check notepads for prior learnings. Delegate every task to sisyphus-junior using 6-section format with 30+ line prompts. Verify EVERY change by reading modified files. Store learnings in notepads.
MUST NOT DO: Write code directly. Trust subagent self-reports without verification. Skip any task in the plan.
CONTEXT: Plan location: .claude/omo/plans/{filename}.md. Notepads: .claude/omo/notepads/. State: .claude/omo/boulder.json. Delegate to sisyphus-junior subagents for all code changes.

Step 5: Completion

After Atlas finishes:

• Update boulder.json: "active_plan": null, "agent_type": null
• Store final learnings in .claude/omo/notepads/{plan-slug}/learnings.md
• Report results to user

Failure Handling

If Atlas reports unresolvable failures:

1. Update boulder.json: "active_plan": null
2. Document failures in notepads
3. Suggest /plan to revise the approach
