What it does

New Page is an agent skill from justrach/merjs. Scaffold a new merjs page. Use when the user wants to create a new page, route, or view.

Its SKILL.md is about 360 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 Development. 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 page

Example prompts

  • “/new-page”

Workflow steps

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

  1. Create app/$ARGUMENTS.zig with this template
  2. Replace PAGE_TITLE and PAGE_DESCRIPTION with sensible values derived from the page name
  3. Run zig build codegen to regenerate routes
  4. Confirm the new route appears in src/generated/routes.zig
  5. Tell the user the route is available at the mapped URL path

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 Page loads about 361 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 122 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~361

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 page

Scaffold a new page at app/$ARGUMENTS.zig that follows the merjs conventions.

Steps

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

pub const meta: mer.Meta = .{
    .title = "PAGE_TITLE",
    .description = "PAGE_DESCRIPTION",
};

const page_node = page();

pub fn render(req: mer.Request) mer.Response {
    return mer.render(req.allocator, page_node);
}

fn page() h.Node {
    return h.div(.{ .class = "page" }, .{
        h.h1(.{}, "PAGE_TITLE"),
    });
}
  1. Replace PAGE_TITLE and PAGE_DESCRIPTION with sensible values derived from the page name
  2. Run zig build codegen to regenerate routes
  3. Confirm the new route appears in src/generated/routes.zig
  4. Tell the user the route is available at the mapped URL path

Conventions

  • Every app/ page MUST export pub const meta: mer.Meta
  • Every page MUST export pub fn render(req: mer.Request) mer.Response
  • Use the h DSL (mer.h) for HTML — prefer comptime nodes
  • For dynamic routes, use bracket syntax: app/users/[id].zig → /users/:id
  • app/index.zig maps to /
  • app/foo/index.zig maps to /foo
  • Add pub const prerender = true; for static pages that don't need request data
