 Use Python 3.9+ and the standard library. The optional upstream skill-creator quick_validate.py requires PyYAML; if missing, report the missing dependency rather than substituting an unreported result.
 
+For this repository, run the checks required by AGENTS.md once on the final relevant baseline, including the available skill-creator validator. Unit tests already cover validator smoke behavior and installer safety; do not stack their equivalent standalone examples after a passing run. Instruction changes need a focused static review of representative decisions, not wording-matching unit tests. Installation comparison is for an installation task, not a requirement that a contributor's active global prompt equal the template.
+
+For tasks using the skill, select checks through [verification scope and causal repair](../skills/codex-subagent-router/references/engineering-workflow.md). Preserve required checks; reuse unaffected evidence and stop when the relevant outcome is supported. Static scenarios remain expectations until real authorized forward tests observe behavior. Do not claim this policy reduced elapsed time, cost or defects without measurements.

 ## Compatibility with other skills
 
 Do not automatically rewrite unrelated skills. Older orchestration skills may assume forked workspaces, a close tool, or a Sol-only parent. Resolve conflicting applicable instructions according to host precedence and identify the exact remaining gate. For a coordinated migration, explicitly include those files and their project-specific requirements.
