Pre-build validation for Expo and React Native apps. Use before running 'eas build --profile production' to ensure compliance with 2026 store rules (Android 15, iOS Privacy Manifests, 16KB Page Size), validate auto-increment, check environment variables, and verify Firebase/Sentry configs.
Query Mozilla telemetry data directly from BigQuery using the bq CLI. Use when the user wants to run SQL against Firefox telemetry, analyze Windows version distribution, count DAU/MAU/WAU, query Glean metrics, or investigate user populations. Triggers on "bigquery", "bq", "telemetry query", "DAU", "MAU", "Windows distribution", "macOS distribution", "Darwin version", "Linux distribution", "kernel version", "client count", "user count", "Glean metrics query", "baseline_clients".
Create a PR with dev as base using the pull request template. Use when opening a new PR.
Use this skill when crafting, reviewing, or improving prompts for LLM pipelines — including task prompts, system prompts, and LLM-as-Judge prompts. Triggers include: requests to write or refine a prompt, diagnose why an LLM produces inconsistent or incorrect outputs, bridge the gap between intent and model behavior, reduce ambiguity in instructions, add few-shot examples, structure complex prompts, or improve output formatting. Also use when the user needs help distinguishing specification failures (unclear instructions) from generalization failures (model limitations), or when iterating on prompts based on observed failure modes. Do NOT use for general coding tasks, document creation, or non-LLM writing.
Guide feature development for full-stack applications with architecture focus. Covers Next.js App Router patterns, NestJS backend services, database models, data workflows, and seamless integration. Use when adding new features, refactoring existing code, or planning major changes.
Write TypeScript and JavaScript code like a top engineer using functional programming principles. Use when writing new code, reviewing existing code, or refactoring TS/JS projects. Applies pure functions, immutability, function composition, higher-order functions, declarative style, and avoiding shared state using native patterns only (no external libraries). Always analyzes the existing codebase first to understand patterns and conventions before making changes or suggestions.
Guide for adding new environment variables to the codebase. Ensures env.ts schemas include descriptions and .env.example is kept in sync. Triggers on: add env variable, new environment variable, env.ts change, add config variable, INKEEP_, adding to .env.
Design experiment plans with progressive stages — initial implementation, baseline tuning, creative research, and ablation studies. Plan baselines, datasets, hyperparameter sweeps, and evaluation metrics. Use when planning experiments for a research paper.
Revise papers based on reviewer feedback. Map reviewer concerns to specific sections, apply targeted edits, run additional experiments if needed, and verify improvements. Use after receiving peer review with revision requests.
Upstream codebase exploration for open source contribution. Outputs contribution guidelines, PR patterns, and maintainer expectations. Triggers: "pr research", "upstream research", "contribution research", "explore upstream repo".
Inspect and summarize local Codex/Claude session logs using the ccbox CLI (projects, sessions, history). Use when asked to list discovered projects, find sessions for the current repo/folder, print a session timeline, or produce an evidence-based “what happened” report from a session .jsonl log under CODEX_SESSIONS_DIR.
Write WeChat Official Account articles from the perspective of an AI product manager. Covers AI product teardowns, scenario-based solutions, efficiency improvement practices, product methodologies, and industry observations.
