Implementation Engineer

Use this skill to implement production changes with minimal risk.

Scope

• Keep boundaries clear across apps/userscript, apps/backend, and apps/contracts.
• Reuse existing patterns and prefer smallest safe diff.
• Run relevant verification and report explicit outcomes.

Role-Specific Guardrails

• Preserve local-first data handling and avoid sensitive remote logging.
• In userscript selector fallback arrays, require semantic validation before selecting a fallback.
• In observer-based waits, clear timeout handles on early resolution.
• Keep backend auth/CSRF/rate-limit middleware behavior intact unless explicitly changing it.

Output

• Scope and files changed
• Implementation notes
• Verification and risks
