Fastly Agent Toolkit

Claude Code: /plugin marketplace add anthropics/claude-plugins-official → /plugin install fastly-agent-toolkit@claude-plugins-official

The choice between the two test paths is the toolkit's main judgement call. Falco runs VCL locally in under a second and suits a tight loop; Fastly Fiddle compiles on production points of presence, which is the only way to exercise geolocation data, WAF, ESI, shielding, rate limiting and real cache behaviour, at the cost of a ten to twenty second edge sync per publish and no authenticated API access. A third skill covers XVCL, a transpiler that adds loops, functions, constants and includes to VCL and resolves all of it at compile time; it is flagged as absent from training data, which is precisely why the skill has to exist. Compute and Wasm work routes elsewhere, to Viceroy or Fastlike, and the CLI skill handles real deployments.
