description	Execute a plan step by step. Reads plan.md in the current working directory or a plan from the conversation context, then implements each subtask sequentially.

Execute Skill

Implement a task breakdown plan step by step.

Plan Resolution

1. If plan.md exists in the current working directory, use it.
2. Otherwise, look for a plan in the current conversation context (e.g. output from the breakdown skill).
3. If no plan is found, ask the user to provide one or run breakdown first.

Execution Flow

1. Present the plan: Show the full list of subtasks to the user and confirm before starting.

2. Implement step by step: For each leaf subtask in order:

   • Announce which subtask you are starting (e.g. ## Step 1.1: <subtask name>)
   • Read relevant source files to understand the current state
   • Implement the changes
   • Verify the changes work (run tests, type checks, etc. if applicable)
   • Mark the subtask as done and briefly report what was done

3. Update plan.md: If the plan was loaded from plan.md, update the file directly — change - [ ] to - [x] for each completed subtask. This keeps the file in sync with actual progress so that future sessions can resume from where you left off.

4. Report progress: After completing each subtask, show the updated checklist with completed items checked off.

5. Handle issues: If a subtask is blocked or unclear:

   • Stop and ask the user for clarification
   • Do NOT skip subtasks or guess at requirements

Batch Size

• By default, execute up to M size worth of subtasks in one batch, then pause and ask the user whether to continue.
  • For example, if there are three consecutive S subtasks, execute up to two or three of them (roughly M equivalent) before pausing.
  • If a single subtask is M, execute that one subtask and then pause.
  • XS and S subtasks can be grouped together as long as their combined effort does not exceed M.
• If the user explicitly requests a larger batch (e.g. "do all of them", "keep going until done", "execute through step 3"), follow that instruction.

Guidelines

• Follow the plan's order and scope. Do not add work beyond what the plan specifies.
• Keep each step's changes focused and minimal — one subtask at a time.
• If the plan turns out to be wrong or outdated mid-execution, stop and discuss with the user before continuing.
