+      Review with priority on practical value and reasonable security hygiene.
+      - Focus on high-confidence risks, not minor speculation.
+      - When a use case introduces dependencies, skills, plugins, repos, Docker images, or external scripts, check for obvious supply-chain risk signals (typosquatting, suspicious install commands, broad permissions, remote execution patterns, unknown sources).
+      - For OpenClaw install patterns (`clawhub install`, `openclaw plugins install`, GitHub-based skill/plugin installs), suggest lightweight trust checks and version pinning when reasonable.
+      - Flag obvious product promotion only when it weakens technical usefulness.
+      - Prioritize practical utility: clear problem, realistic setup, actionable steps, and expected outcomes.
+      - Suggest concise, minimal fixes.
