What it does

When you ask a question about the Effect TypeScript framework, this skill tells the agent to download the Effect source repository into the project's references folder, search that code with an explore sub-agent, and base its answer on the actual source and docs rather than memory. It is aimed at keeping answers about Effect's APIs and patterns accurate and traceable to specific files.

Great for

  • TypeScript developers working in a codebase that uses the Effect framework
  • Engineers who want answers about Effect APIs grounded in the current source code
  • Teams onboarding new members onto Effect patterns

Skip it if

  • Projects that do not use Effect, since the skill only applies to Effect questions
  • Quick answers where cloning a full repository is unnecessary overhead, since each session may fetch the repo
  • Environments without network access or without git, because the skill depends on cloning from GitHub

Try asking

  • “How do I handle errors with Effect.catchTag in this codebase?”
  • “Show me how Effect layers are composed, with references to the source files”
  • “What is the difference between Effect.gen and Effect.fn according to the Effect source?”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Check that the cloned repo lands in the project's .opencode/references folder and not inside the skill folder, as the instructions specify.
  • Ask for specific file references so you can verify the answer against the Effect source yourself.
  • Note that the skill points to the effect-smol repository; confirm it matches the Effect version your project uses.
