What it does

Effect is an agent skill from standardnguyen/rolandcode. Answer questions about the Effect framework

Its SKILL.md is about 190 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: OpenCode with all telemetry removed. Clean builds, no phone-home. The licence is MIT.

Example prompts

  • “/effect”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Clone the Effect repository: https://github.com/Effect-TS/effect-smol to
  2. Use the explore agent to search the codebase for answers about Effect patterns, APIs, and concepts
  3. Provide responses based on the actual Effect source code and documentation

What it can do on your machine

Read from SKILL.md and the folder at commit 81c03cd. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Effect loads about 192 tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 93 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~192

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Answer questions about the Effect framework

Effect

This codebase uses Effect, a framework for writing typescript.

How to Answer Effect Questions

  1. Clone the Effect repository: https://github.com/Effect-TS/effect-smol to .opencode/references/effect-smol in this project NOT the skill folder.
  2. Use the explore agent to search the codebase for answers about Effect patterns, APIs, and concepts
  3. Provide responses based on the actual Effect source code and documentation

Guidelines

  • Always use the explore agent with the cloned repository when answering Effect-related questions
  • Reference specific files and patterns found in the Effect codebase
  • Do not answer from memory - always verify against the source
