What it does

New API is an agent skill from justrach/merjs. Scaffold a new merjs API route. Use when the user wants to create a new API endpoint.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering REST APIs. It works with WebAssembly. The repository describes itself as: A Zig-native web framework. File-based routing, SSR, type-safe APIs, WASM client interactivity. No Node. No npm. Just zig build serve. The licence is MIT.

When your agent uses it

  • The user wants to create a new API endpoint
  • Tasks that involve REST APIs

Example prompts

  • “/new-api”

Workflow steps

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

  1. Create api/$ARGUMENTS.zig with this template
  2. Adapt the Response struct fields based on what the user described
  3. Run zig build codegen to regenerate routes
  4. Confirm the route appears at /api/$ARGUMENTS

What it can do on your machine

Read from SKILL.md and the folder at commit 28b53d8. 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 (its code samples are zig).

    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

New API loads about 302 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 103 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~302

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.

Create a new merjs API route

Scaffold a new API route at api/$ARGUMENTS.zig.

Steps

  1. Create api/$ARGUMENTS.zig with this template:
zig
const mer = @import("mer");

const Response = struct {
    // Define your response fields here
    message: []const u8,
};

pub fn render(req: mer.Request) mer.Response {
    return mer.typedJson(req.allocator, Response{
        .message = "hello",
    });
}
  1. Adapt the Response struct fields based on what the user described
  2. Run zig build codegen to regenerate routes
  3. Confirm the route appears at /api/$ARGUMENTS

Conventions

  • API routes live in api/ and map to /api/...
  • Use mer.typedJson(allocator, value) to return typed JSON responses
  • Use mer.json(string) for raw JSON strings
  • Access request body via req.body, method via req.method
  • Access query string via req.query_string
  • Access cookies via req.cookie("name")
  • For validation, use dhi: const dhi = @import("dhi_validator");
  • API routes do NOT need pub const meta
