Operate and verify queues with or without Horizon; safe worker flags, failure handling, and test strategies
Build AI agents and agentic workflows. Use when designing/building/debugging agentic systems: choosing workflows vs agents, implementing prompt patterns (chaining/routing/parallelization/orchestrator-workers/evaluator-optimizer), building autonomous agents with tools, designing ACI/tool specs, or troubleshooting/optimizing implementations. **PROACTIVE ACTIVATION**: Auto-invoke when building agentic applications, designing workflows vs agents, or implementing agent patterns. **DETECTION**: Check for agent code (MCP servers, tool defs, .mcp.json configs), or user mentions of "agent", "workflow", "agentic", "autonomous". **USE CASES**: Designing agentic systems, choosing workflows vs agents, implementing prompt patterns, building agents with tools, designing ACI/tool specs, troubleshooting/optimizing agents.
This skill provides comprehensive knowledge for implementing Cloudflare Turnstile, the CAPTCHA-alternative bot protection system. It should be used when integrating bot protection into forms, login pages, signup flows, or any user-facing feature requiring spam/bot prevention. Turnstile runs invisible challenges in the background, maintaining excellent user experience while blocking automated traffic. Use when: Adding bot protection to forms, implementing login security, protecting API endpoints from abuse, migrating from reCAPTCHA/hCaptcha, encountering CSP errors with Turnstile, handling token validation failures, implementing E2E tests with Turnstile, integrating with React/Next.js/Hono applications, or debugging error codes 100*, 300*, 600*. Keywords: turnstile, captcha, bot protection, cloudflare challenge, siteverify, recaptcha alternative, spam prevention, form protection, cf-turnstile, turnstile widget, token validation, managed challenge, invisible challenge, @marsidev/react-turnstile, hono turnstile, workers turnstile
Integrate TheSys C1 Generative UI API to stream interactive React components (forms, charts, tables) from LLM responses. Supports Vite+React, Next.js, and Cloudflare Workers with OpenAI, Anthropic Claude, and Workers AI. Use when building conversational UIs, AI assistants with rich interactions, or troubleshooting empty responses, theme application failures, streaming issues, or tool calling errors.
Hono 4.x web framework patterns. Use when building APIs, middleware, routing, or server-side applications. Covers multi-runtime support (Node, Bun, Cloudflare Workers), validation, CORS, and error handling.
(Industry standard: Sequential Agent / Agent as a Tool) Primary Use Case: Delegating a well-defined task to a worker agent, verifying its execution, and repeating if necessary. Inner/outer agent delegation pattern. Use when: work needs to be delegated from a strategic controller (Outer Loop) to a tactical executor (Inner Loop) via strategy packets, with verification and correction loops.
Deploys applications to TrueFoundry. Handles single HTTP services, async/queue workers, multi-service projects, and declarative manifest apply. Supports `tfy apply`, `tfy deploy`, docker-compose translation, and CI/CD pipelines. Use when deploying apps, applying manifests, shipping services, or orchestrating multi-service deployments.
Review a PR linked to a kspec task, post findings as inline comments, and merge only when all quality gates pass. You NEVER fix code — you review and comment. If issues found, kick back to worker.
Implement thread-safe code, mutexes, semaphores, async/await patterns, and concurrent data structures. Use when handling parallel operations, race conditions, or building high-performance concurrent systems.
Store objects with R2's S3-compatible storage on Cloudflare's edge. Use when: uploading/downloading files, configuring CORS, generating presigned URLs, multipart uploads, managing metadata, or troubleshooting R2_ERROR, CORS failures, presigned URL issues, or quota errors.
Configures the iii engine via iii-config.yaml — modules, adapters, queue configs, ports, and environment variables. Use when deploying, tuning, or customizing the engine.
Store objects with R2's S3-compatible storage on Cloudflare's edge. Use when: uploading/downloading files, configuring CORS, generating presigned URLs, multipart uploads, managing metadata, or troubleshooting R2_ERROR, CORS failures, presigned URL issues, quota errors, 429 rate limits, list() metadata missing, or platform outages. Prevents 13 documented errors including r2.dev rate limiting, concurrent write limits, API token permissions, and CORS format confusion.
