Userscript Implementation
Use this skill for userscript-specific behavior, metadata, DOM extraction, and portal compatibility.
Scope
- Validate Tampermonkey metadata changes (
@match, @grant, @connect).
- Keep UI rendering CSP-safe and portal-compatible.
- Preserve sync privacy model and multi-card behavior.
Role-Specific Guardrails
- Keep
@connect least-privilege.
- Prefer class-based styling and
GM_addStyle for new UI.
- For selector fallback arrays, continue evaluation until semantic card validation passes.
- In observer + timeout flows, clear pending timers on early resolve.
Output
- Behavioral impact by portal/card
- Verification and manual-check outcomes
- Risks and compatibility notes
