Execution — Execute Plans at Scale

TL;DR

• Use when running an approved plan from cm-planning
• Reads handoff/plan.json or openspec/changes/[name]/tasks.md
• Writes handoff/exec.json
• Always verify before reporting done
• Next cm-code-review

Role: Lead Developer. You execute plans systematically with quality gates at every checkpoint.

Step 0: Load Working Memory (MANDATORY)

Per _shared/helpers.md#Load-Working-Memory. After EACH completed task: _shared/helpers.md#Update-Continuity.

Step 1: Pre-flight Skill Coverage Audit

Scan plan tasks for tech keywords, cross-reference cm-skill-index, check installed skills, and use npx skills find when the plan reaches beyond current coverage. If codegraph or cm-codeintell context is available, inject it into agent prompts so execution skips redundant repo searching.

Step 2: Choose Mode

Have a plan with independent tasks?
├─ Need SPEED + QUALITY on 3+ tasks?
│   └─ YES → Mode E (TRIZ-Parallel) ★ recommended
├─ One non-trivial task, want multi-perspective without subagent cost?
│   └─ YES → Mode F (Party, persona rotation)
├─ Multiple independent failures across subsystems?
│   └─ YES → Mode C (Parallel Dispatch)
├─ Autonomous loop with backlog (`/cm-start` flow)?
│   └─ YES → Mode D (RARV)
├─ Plan has independent tasks, stay in this session?
│   └─ YES → Mode B (Subagent-Driven)
└─ Otherwise
    └─ Mode A (Batch Execution)

Action: Pick exactly one mode, read only that reference, and execute from there.

Conditional References

• Mode B / E / F → also read references/persona-dispatch.md
• Task touches auth, files, subprocess, DOM, config paths, or user input → MUST read references/security-rules.md before writing code

Karpathy Discipline — Surgical Changes

• Touch only what the task requires. No "while I'm here" refactors.
• Match existing style even if you would write it differently.
• Notice unrelated dead code? Mention it, do not delete it.
• Clean only your own orphans. Pre-existing dead code stays unless asked.
• Diff test: every changed line must trace to the task.

The Bottom Line

Choose your mode → load that one reference → execute systematically → review at every checkpoint.
