+Read the complete external guidance before:
 
+- creating a skill
+- changing skill discovery or behavior, resource organization, progressive
+  disclosure, scripts, or tool workflows
+- performing a periodic guidance refresh or updating this checklist
+
+Source:
 https://platform.claude.com/docs/en/agents-and-tools/agent-skills/best-practices
 
-Follow that guidance strictly. If the page cannot be read, report the blocker

+Follow the source strictly when it applies. If it cannot be read, report the
+blocker before editing unless the user explicitly says to continue.
+
+For routine wording, spelling, and formatting edits that do not change skill
+behavior or structure, use only the local checklist below.
+
+## Routine Edit Checklist
+
+- Preserve the skill's behavior, triggers, structure, and file references.
+- Keep instructions concise and use consistent terminology.
+- Keep names and descriptions specific and truthful about what the skill does
+  and when it applies.
+- Keep file references directly linked from `SKILL.md` and use forward slashes.
+- Avoid adding time-sensitive guidance or unnecessary choices and explanations.
+- Verify referenced paths and any repository validation affected by the edit.
