The explanation below is AI-generated. Please verify it against the sources.

fastly-agent-toolkit is a collection of skills that let AI coding agents work with the Fastly platform and related edge-computing tools. According to the README, it bundles seven skills covering the Fastly platform itself, the Fastly CLI, Fastly Fiddle, Falco, Fastlike, Viceroy, and the XVCL transpiler. Each skill lives under a skills/ directory with a SKILL.md entrypoint and a references/ folder containing detailed topic files. The README notes that agents must be allowed to read the references/ directory, or they will miss important context. Installation is supported via the skills CLI, manual copy into .agents/skills/, or agent-specific setups for Claude Code, Codex, Swival, Qwen Code, and Gemini CLI.

Overview

According to the README, fastly-agent-toolkit is not a SaaS but a toolkit/plugin: a set of skill files (SKILL.md plus references) that AI coding agents load to gain knowledge about working with Fastly's platform and edge-computing tooling.

What you can do with fastly-agent-toolkit

  • Use the fastly skill for the Fastly platform: services, caching, VCL, WAF, TLS, DDoS protection, purging, and API usage
  • Use fastly-cli to manage services, compute apps, logging, WAF, TLS, key-value stores, and stats via the Fastly CLI
  • Use fastly-fiddle to test VCL against real Fastly edge infrastructure, including assertion-based tests, the Fiddle HTTP API, shareable bug reproductions, and CI integration
  • Use falco for VCL development: linting, testing, simulation, formatting, REPL, and Terraform integration
  • Use fastlike to run Fastly Compute locally (Go-based), covering backend configuration, builds, and testing
  • Use viceroy to run Fastly Compute locally (WASM-based), covering serving, configuration, testing, and SDK adaptation
  • Use xvcl for the XVCL VCL transpiler: syntax extensions, subroutines, header manipulation, and caching logic
  • Install selected skills via the skills CLI, manual copy, or agent-specific methods (Claude Code, Codex, Swival, Qwen Code, Gemini CLI)
