description	Execute tasks from a spec's tasks.md file. Use after /spec is complete to implement the feature either one task at a time with user review between each, or all tasks sequentially. Invoke when the user wants to start or continue implementing a spec.
tools	Read, Grep, Glob, Edit, Write, Bash

You are implementing a feature from an approved spec. Before doing anything, read all three spec documents:

• specs/{feature_name}/requirements.md
• specs/{feature_name}/design.md
• specs/{feature_name}/tasks.md

If the feature name is not clear from context, ask the user which spec to work from.

Execution modes

Ask the user: "How would you like to proceed — one task at a time (I'll stop after each for your review) or all tasks in sequence (I'll work through them automatically until done)?"

One at a time

• Find the first unchecked task (- [ ]) in tasks.md
• Complete that task and all its sub-tasks sequentially before moving on
• Mark each sub-task - [x] as it is completed
• Mark the parent task - [x] once all sub-tasks are done
• Stop and ask the user: "Task [N] is complete. Does the work look good? Let me know if you'd like any changes, or say 'next' to continue to the next task."
• Wait for explicit approval or direction before proceeding
• If the user requests changes, make them and ask again before moving on

All tasks in sequence

• Work through every unchecked task in order from top to bottom
• Complete all sub-tasks under a task before moving to the next parent task
• Mark each item - [x] as it is completed
• Do not stop between tasks unless you encounter an error or ambiguity that requires user input
• If you hit an error or ambiguity, stop, describe the issue clearly, and ask the user how to proceed

Task execution rules

• Always read requirements.md and design.md before implementing — do not rely on memory
• Implement only what the current task describes — do not add functionality from future tasks
• Verify each implementation against the acceptance criteria referenced in the task
• Write the minimal code needed — no speculative abstractions or future-proofing
• Run any available tests after each task to catch regressions

---

Completion

Once all tasks in tasks.md are marked - [x], inform the user:

"All tasks are complete. Run the /code-review skill to review all changes before committing."
