What is dotfiles AGENTS.md?

A set of guidelines for HorneroConfig, a dotfiles project for configuring a user's development environment. It describes design principles such as theme support, modularity, centralized configuration, fallbacks, and secure defaults, plus shell-script conventions.

Use it when creating or editing HorneroConfig themes, configuration systems, user scripts, command-line options, logging, or dependency fallbacks.

It gives agents consistent rules for writing reliable configuration and scripts that handle missing optional dependencies safely.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00780	$0.00780
Opus 5	$0.00390	$0.00390
Sonnet 5	$0.00156	$0.00156
Haiku 4.5	$0.00078	$0.00078

Security

Grade A, and why

dotfiles AGENTS.md 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 6d 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.

AI Agent Guidelines for HorneroConfig

For AI coding assistants and automated tools
Last Updated: 2026-02-27

Purpose

This is the authoritative guide for AI agents working on HorneroConfig. Follow the Hornero Bird philosophy: build robust, functional, adaptable, beautiful, and modular environments.

Quick Reference

Core Principles (The Hornero Way)

Theme-Adaptive - All visuals adapt to any color palette automatically
Modular - Components work independently yet integrate seamlessly
Single Source of Truth - Configuration flows from centralized sources
Graceful Degradation - Function even with missing dependencies
Security by Default - Never commit secrets, validate all inputs

See Architecture Philosophy for detailed principles.

Essential Standards

Scripts Must:

Use EasyOptions for CLI parsing
Include set -euo pipefail
Follow naming: dots-* for user scripts, snake_case for functions/vars
Handle errors gracefully with logging
Work without optional dependencies (fallbacks required)

See Development Standards for complete requirements.

Key Systems

Appearance Themes - Apply-once theme packs + live wallpaper/scheme/GTK controls
Smart Colors - Semantic color adaptation cached in ~/.cache/dots/smart-colors/
Quickshell - Unified QML desktop shell (bar, launcher, dashboard, notifications, AI chat) with multi-layout bar (bar.position: left/right/top/bottom, bar.style: attached/floating/dock) and shell presets (~/.local/share/dots/shell-presets/*.json, applied live via dots-quickshell preset apply <name> or the in-shell layout picker)
Hornero C++ Plugin - Performance-critical Quickshell extensions (image analysis, audio, calculator)
Dots CLI - Unified script interface
Chaotic-AUR - Precompiled AUR packages for faster installation

See System Architecture for detailed architecture.

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.
