oh-my-ccg Implementation Phase

You are executing the RPI Impl phase. Execute the plan mechanically.

Prerequisites

• RPI state must be in PLAN phase (or resuming IMPL)
• Tasks must be defined in state/artifacts

Workflow

Step 1: Restore State

Use the oh-my-ccg-tools MCP server's rpi_state_read tool. Load the task list and current progress.

Step 2: Assess Parallelism

Check task dependencies:

• If multiple independent tasks exist → use Team mode for parallel execution
• If tasks are sequential → execute one by one with executor agent

Step 3: Execute Tasks

For each task (or batch of parallel tasks):

1. Route to appropriate model for prototype (via MCP tools):

   • Frontend tasks → call ask_gemini(agent_role="designer") for prototype, then executor rewrites to production
   • Backend tasks → call ask_codex(agent_role="architect") for prototype, then executor rewrites to production
   • General tasks → executor implements directly (no external model needed)

2. Executor implements:

   • Read task spec completely
   • Explore existing code patterns
   • Rewrite prototype to production quality (NEVER apply external model output directly)
   • Run type checks and tests

3. Side-effect review (MANDATORY before moving to next task):

   • Verify changes stay within task scope
   • Check no unintended dependencies affected
   • Confirm interfaces match expectations

Step 4: Cross-Review

After all tasks complete, run dual-model cross-review using MCP tools in parallel:

• ask_codex(agent_role="code-reviewer", background=true) — reviews logic/security
• ask_gemini(agent_role="designer", background=true) — reviews patterns/maintainability

Collect both results via check_job_status, then:

• Fix any Critical findings immediately
• Log Warnings for review phase

Step 5: Verify

Run verifier agent:

• All tests pass
• Build succeeds
• No type errors
• Constraints satisfied

Step 6: Update State

Use rpi_state_write MCP tool to:

• Mark tasks complete in state
• Transition phase to "impl"
• If all tasks done → prompt for /oh-my-ccg:review

Ralph Integration

If ralph mode is active:

• Execute → Verify → Pass? → Complete
• Execute → Verify → Fail? → Fix → Repeat (up to max iterations)
