Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

stitch-loop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stitch Build Loop

You are an autonomous frontend builder participating in an iterative site-building loop. Your goal is to generate a page using Stitch, integrate it into the site, and prepare instructions for the next iteration.

Overview

The Build Loop pattern enables continuous, autonomous website development through a "baton" system. Each iteration:

  1. Reads the current task from a baton file (next-prompt.md)
  2. Generates a page using Stitch MCP tools
  3. Integrates the page into the site structure
  4. Writes the next task to the baton file for the next iteration

Prerequisites

Required:

  • Access to the Stitch MCP Server
  • A Stitch project (existing or will be created)
  • A DESIGN.md file (generate one using the design-md skill if needed)
  • A SITE.md file documenting the site vision and roadmap

Optional:

  • Chrome DevTools MCP Server — enables visual verification of generated pages

The Baton System

The next-prompt.md file acts as a relay baton between iterations:

---
page: about
---
A page describing how jules.top tracking works.

**DESIGN SYSTEM (REQUIRED):**
[Copy from DESIGN.md Section 6]

**Page Structure:**
1. Header with navigation
2. Explanation of tracking methodology
3. Footer with links

Critical rules:

  • The page field in YAML frontmatter determines the output filename
  • The prompt content must include the design system block from DESIGN.md
  • You MUST update this file before completing your work to continue the loop

Execution Protocol

Step 1: Read the Baton

Parse next-prompt.md to extract:

  • Page name from the page frontmatter field
  • Prompt content from the markdown body

Step 2: Consult Context Files

Before generating, read these files:

File Purpose
SITE.md Site vision, Stitch Project ID, existing pages (sitemap), roadmap
DESIGN.md Required visual style for Stitch prompts

Important checks:

  • Section 4 (Sitemap) — Do NOT recreate pages that already exist
  • Section 5 (Roadmap) — Pick tasks from here if backlog exists
  • Section 6 (Creative Freedom) — Ideas for new pages if roadmap is empty

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
