Review a skill as an execution contract, not as prose. Trace how an agent would enter, load, delegate, produce artifacts, and verify results; then report the smallest changes that would improve that chain.

Use subagents only as an evaluation surface or for independent broad research. The lead agent owns the review, final calibration, and file edits. Pass raw artifacts and task-local scope to subagents; do not pass the intended answer.

without breaking the workflow.
Lead with findings, ordered by severity. Keep each finding concrete:
textP1 - <short title> File: <path>:<line> Why it matters: <execution or output risk> Evidence: <quoted phrase, command result, or linked resource> Fix: <smallest owning-file change> Validation: <command or smoke that should prove it>
After findings, add open questions only when they block a safe change. If the user asked for edits, include changed files and validation results after the findings. Default to the user's language.
