# Executing Plans

Implement an approved plan in controlled batches with explicit verification.

## Required Start

Announce: `I'm using the executing-plans skill to implement this plan.`

## Process

```dot
digraph executing_plans {
    "Load and review plan" [shape=box];
    "Concerns?" [shape=diamond];
    "Raise with user" [shape=box];
    "Set up worktree" [shape=box];
    "Execute next task" [shape=box];
    "Run verification" [shape=box];
    "More tasks?" [shape=diamond];
    "Invoke finishing-a-development-branch" [shape=doublecircle];

    "Load and review plan" -> "Concerns?";
    "Concerns?" -> "Raise with user" [label="yes"];
    "Raise with user" -> "Load and review plan" [label="plan updated"];
    "Concerns?" -> "Set up worktree" [label="no"];
    "Set up worktree" -> "Execute next task";
    "Execute next task" -> "Run verification";
    "Run verification" -> "More tasks?";
    "More tasks?" -> "Execute next task" [label="yes"];
    "More tasks?" -> "Invoke finishing-a-development-branch" [label="no"];
}
```

### Step 1: Load and Review Plan
1. Read the plan completely.
2. Review critically — identify any questions or concerns.
3. If concerns: raise them with the user before starting.
4. If no concerns: create task tracking and proceed.

### Step 2: Set Up Workspace
Ensure isolated workspace is ready (`using-git-worktrees`).

### Step 3: Execute Tasks
For each task:
1. Follow each step exactly (plan has bite-sized steps with checkboxes).
2. Run verifications as specified.
3. Mark task complete.
4. For tasks involving UI/UX or frontend implementation, apply guidance from `frontend-design`.

**Note:** Superpowers works significantly better with subagent support. If subagents are available, use `subagent-driven-development` instead — the quality of work will be higher with fresh-context-per-task and two-stage review gates.

## Engineering Rigor for Complex Tasks

When a task is architectural, high-risk, or touches cross-module boundaries:
- Validate the approach against requirements and constraints before coding.
- Identify edge cases and error paths specific to this task.
- Consider simpler architectures or alternative approaches.
- Ensure changes remain maintainable and don't create hidden coupling.
- If 2 implementation attempts fail, pause and reassess the approach rather than forcing a third attempt.

## Execution Rules

- Do not skip plan steps unless user approves deviation.
- Never start implementation on main/master branch without explicit user consent — ensure isolated workspace is ready first.
- Keep edits scoped to the current task.
- Do not claim completion without fresh command output.

**Stop immediately and ask for clarification — never guess — when:**
- A dependency is missing or unavailable.
- The plan has a critical gap that prevents starting.
- An instruction is unclear or contradictory.
- Verification fails repeatedly (2+ attempts).

## Context Hygiene

For each task, keep only:
- Current task details
- Constraints
- Relevant prior decisions
- Verification evidence

Do not carry long historical summaries. Never forward full session history to subagents — construct their prompts from scratch with only the items above.

## Completion

After all tasks pass verification:
1. Announce `finishing-a-development-branch`.
2. Invoke `finishing-a-development-branch`.
