Implement a Change

Implement a feature or fix following project standards.

Input

Primary input ($ARGUMENTS): an Issue number/URL, a plan file path, or free-text description. Optional: -- <additional context> for execution guidance.

Unattended mode: --unattended skips plan approval and proceeds without confirmation prompts.

Process

Step 1: Understand the Work

Determine the input type and extract requirements. Detect the Issue tracker provider (see issue-operations).

• Issue — fetch using the project's Issue tracker (see issue-operations). Parse title, requirements, acceptance criteria, labels, sub-issues, comments. Add labels if missing. When the Issue has sub-issues, treat each as a separate task and close them as you complete them.
• Plan file — extract goals, requirements, constraints, acceptance criteria.
• Free-text — parse scope and constraints.
