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.

Fable 5.1 $0.00057 $0.04860
Opus 5.5 $0.00023 $0.01944

Security

Grade A, and why

fork-and-customize scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 566 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fork & Customize — Ballot Endorsement Guide

You are helping a user fork and customize the ballot-endorsement-guide repository for their own organization, election, and jurisdiction. This is a headless Next.js full-stack app that lets an organization show their followers which candidates they have endorsed on that voter's specific ballot.

Work through the sections below in order. Each section has a goal and a set of questions to ask. Do not skip ahead — wait for the user's answers before proceeding. Summarize what you will change at the end of each section before making edits.

Phase 0 — Orientation

Before you start, make sure you understand the repo layout. The key files you will be editing:

File Purpose
frontend/src/lib/app-config.ts Central config hub — branding, geography, district layers, geocoding provider
frontend/src/app/globals.css Color theme (Tailwind CSS 4 @theme inline block)
frontend/src/app/layout.tsx Fonts and HTML metadata
frontend/src/app/page.tsx Main UI — header, address input, results table, footer
frontend/data/endorsements.yaml The endorsement dataset
frontend/data/district-maps/<state-slug>/ GeoJSON boundary and district shapefiles
frontend/src/lib/geocoding/providers.ts Geocoding provider implementations
frontend/src/lib/geocoding/types.ts GeocodingProviderName union type
frontend/src/lib/geocoding/index.ts Provider factory
Dockerfile Docker production build
railway.toml Railway deployment config

Read frontend/src/lib/app-config.ts first — it is the single source of truth that drives everything else.

Phase 1 — Organization Branding

Goal: Re-skin the app for the user's organization.

Questions to ask

  1. Do you have an existing website I can view to pull branding from? (colors, logo, fonts, tone). If yes, use WebFetch to visit the site and extract:
    • Primary, secondary, and accent colors
    • Font families (display + body)
    • Organization name and tagline
    • Any logo or favicon assets

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.
