agent

Benchmark any agent skill to measure whether it actually improves performance. Use when the user wants to evaluate, test, or compare a skill against baseline, or when they mention "benchmark", "eval", "skill performance", or "does this skill help". Runs isolated eval sessions with and without the skill, grades outputs via layered grading (deterministic checks + LLM-as-judge), analyzes behavioral signals, and generates a comparison report with a USE / DON'T USE verdict.

Production-grade i18n/l10n for React, Vue, Angular, and Next.js with ICU format and RTL support. Use when setting up or debugging localisation.

Capture exact React element context from a live browser UI and hand it to an AI coding agent as component name, source file path, line number, and HTML. Use when the user wants `react-grab`, element-context copy, component-source lookup from the browser, clipboard-to-agent React debugging, or MCP-backed element selection for React apps. Not for generic browser automation or login/session reuse (`agent-browser`, `playwriter`), broad UI annotation/review (`agentation`), React performance audits (`react-best-practices`), or general design-system work (`design-system`). Triggers on: react-grab, grab element context, copy component to AI, browser component picker, React component inspector, clipboard component source, get element context from browser, grab UI element.

Route server-owned AI workflow work into one Genkit implementation brief. Use when the main job is deciding whether a web/backend/fullstack feature needs reusable flows, tools, retrieval, prompt files, typed contracts, evals, observability, or deployment across Firebase / Cloud Run / another backend runtime. Choose among flow-foundation, tool-and-agent, retrieval-and-prompt, evaluation-and-observability, and deployment-runtime modes; keep direct Firebase app/client SDK integration routed to `firebase-ai-logic`, Firebase platform/operator work routed to `firebase-cli`, and framework-choice comparisons routed to `survey`.
