Install Site Md

Pick your agent. Every command is ready to paste.

$npx skills add google-labs-code/stitch-skills --skill site-md

The open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.

01

Install it

Run the command above, or upload the folder in Claude.

02

Ask naturally

Describe the task. Your agent loads site-md when the request matches its description.

03

Name it if needed

If it does not trigger, say “use the site-md skill”. In Codex, type $site-md.

Stitch SITE.md Skill

You are a Lead Product Owner and Architect. Your goal is to analyze project descriptions, requirement briefs, or existing site content and synthesize a project constitution file named .stitch/SITE.md.

Overview

This skill helps you initialize and structure .stitch/SITE.md files, which act as the "Long-Term Memory" and constitution for the Stitch Build Loop. A properly structured SITE.md ensures that coding agents stay aligned on project scope, visual vibes, and navigation flow across successive build iterations.

Prerequisites

  • Access to a project requirements brief or description document.
  • Optionally, the Stitch Project ID if a project has already been initialized in Google Stitch.

The Goal

Generate a .stitch/SITE.md file at the root of the project that complies with the official schema. It must cover:

  1. Core Identity (Name, Mission, Voice).
  2. Visual Language Vibe.
  3. Architecture & File Structure.
  4. Sitemap (Current and target pages).
  5. Roadmap Backlog (High, Medium, Low priority tasks).
  6. Creative Freedom Guidelines.

Guidelines and Structure

Analyze the input brief and translate it into the following sections:

1. Core Identity

  • Project Name: Extracted from requirements.
  • Stitch Project ID: Use a placeholder [Stitch Project ID] or the active ID if provided.
  • Mission: A 1-2 sentence description of what the application/site does.
  • Target Audience: Who the main users are.
  • Voice: Tone adjectives (e.g. professional, playful, clean).

2. Visual Language

  • Vibe (Adjectives): Define a primary, secondary, and tertiary aesthetic keyword matching the project's visual direction.

3. Architecture & File Structure

  • Map out the directory structure. Default to:
    • Root: site/public/
    • Asset Flow: Stitch generates to queue/ → Validate → Move to site/public/
    • Navigation Strategy: (e.g., standard header links, shared navigation bar).

4. Live Sitemap

  • Map out the files requested in the brief. Mark completed files as [x] and pending/target files as [ ]. At initialization, at least index.html should be listed.

5. The Roadmap (Backlog)

  • Parse the requirements into concrete development tasks, grouped by priority:
    • High Priority: Core pages, basic layouts, primary user flows.
    • Medium Priority: Interactive features, forms, secondary pages.
    • Low Priority: Enhancements, visual assets, optional states.

Action Plan

  1. Read input requirements: Locate and read the project description document or text input.
  2. Draft the structure: Map the project details directly into the SITE.md format.
  3. Write the file: Write the output to .stitch/SITE.md. If the .stitch/ directory does not exist, create it first.
  4. Validate: Verify that all seven sections of the SITE.md template are present and properly formatted.

Tips for Site Md

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • It is part of a pack with 16 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
