create-implementation-plan

The provided code fragment is a declarative planning template intended to standardize and automate creation of implementation plan Markdown files. It is internally consistent with its stated purpose, shows no direct data exfiltration, credential handling, or remote execution patterns, and does not introduce recognizably unsafe dependencies. Its operational risk is low when used as designed, though care should be taken to validate that PlanPurpose inputs are trusted to avoid injecting malformed or harmful plan content into /plan/.
