Load references/full-guide.md before executing detailed commands, applying templates, or relying on examples from this skill.
Keep the work limited to the user-requested target; do not add adjacent improvements unless the user asks.

Confirm the target, available context, constraints, and done-when signal.
Read the relevant section of references/full-guide.md for task-specific details.
Execute the smallest reversible action that satisfies the request.
Verify with read-only evidence first, then document every applied change with rollback commands and post-change validation.
