At a glance

Route HTTP through Effect boundaries instead of raw fetch. An agent skill from UsefulSoftwareCo/executor.

  • Lint flags executor/no-raw-fetch
  • SKILL.md covers Fix Shape, Approved Boundaries, Bad and Good
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Adding networked protocol/provider code

What it does

Wrdn Effect Raw Fetch Boundary is an agent skill from UsefulSoftwareCo/executor. Route HTTP through Effect boundaries instead of raw fetch. Use when lint flags executor/no-raw-fetch or when adding networked protocol/provider code.

Its SKILL.md is about 540 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: The missing integration layer for AI agents. Let them call any OpenAPI / MCP / GraphQL / custom js functions in secure environment. The licence is MIT.

When your agent uses it

  • Lint flags executor/no-raw-fetch
  • Adding networked protocol/provider code

Example prompts

  • “/wrdn-effect-raw-fetch-boundary”

Requirements

  • Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash

What it can do on your machine

Read from SKILL.md and the folder at commit 9ef04e9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Glob
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

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

  • Network

    No URLs in SKILL.md.

    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

Wrdn Effect Raw Fetch Boundary loads about 537 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 219 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~537

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)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.

HTTP in core SDK and protocol plugins should go through Effect services so tests can replace real networks with local protocol fixtures or mock HttpClient layers.

Fix Shape

  • Prefer effect/unstable/http HttpClient and HttpClientRequest for ordinary HTTP calls.
  • Accept a Layer.Layer<HttpClient.HttpClient> option on plugin/provider code when callers need to inject a test client.
  • In tests, use real local servers plus FetchHttpClient.layer or a captured HttpClient service from the test layer.
  • Do not add fetch-shaped abstractions in SDK or plugin seams. If a third-party library truly only accepts fetch, keep the adapter in the owning package, name the forced boundary explicitly, and delegate internally to Effect HttpClient.
  • Do not type new protocol/plugin seams as typeof globalThis.fetch; keep the ambient runtime boundary out of domain and test APIs.
  • Do not patch globalThis.fetch. Replace those tests with a local server, HttpClient layer, or the approved Effect-backed adapter.
  • Do not add a broad allowlist entry unless the file is a platform entrypoint or a temporary migration target.

Approved Boundaries

  • Worker/handler objects whose public API must expose a fetch method.
  • Test calls to a worker or Miniflare binding's .fetch(...) method.
  • Small adapters for libraries that only accept fetch, if the implementation delegates to Effect HttpClient.
  • Browser UI event handlers may remain raw only until app-side boundaries are classified; prefer SDK/client APIs where available.

Bad

ts
const response = await fetch(url);
ts
const fetchImpl = options.fetch ?? globalThis.fetch;

Good

ts
const client = yield * HttpClient.HttpClient;
const response = yield * client.execute(HttpClientRequest.get(url));
ts
const plugin = graphqlPlugin({ httpClientLayer: testHttpClientLayer });
