Sleak AGENTS.md

A guide for Sleak, a tool that helps teams make deliberate choices about product interfaces and visual design.

In plain words
What is it for?
Use it during UI and frontend work, visual reviews, screen refinement, and pre-release design checks.
Why use it?
It gives developers specific design rules and review checks when an interface feels inconsistent, cluttered, or unclear.

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

Sleak 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 2d 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.

What it actually says

AGENTS.md

This repo ships Sleak, a design-decision guide for building intentional product UI.

When to use it

For any UI, frontend, or visual-design work, creating or refining screens, reviewing a design or implementation before ship, or when an interface feels generic, noisy, or lacks a clear primary action, read and follow the guide before making changes:

  • Start at SKILL.md for the core principles and workflow.
  • Run checklist.md as a pre-ship audit.
  • Open the relevant file in references/ for full rules, CSS, and audits.

Read these on demand rather than inlining them, pull in only the reference for the category you're working on.

Core rules (check first)

  1. Concentric corner radius, nested radii follow parent − padding = child; never reuse the same radius on both layers when padding > 0. See references/concentric-radius.md.
  2. Section eyebrows, small kickers above headings weaken when repeated; ≤1 per page, and almost never in the hero. See references/section-eyebrows.md.
  3. Intentional accent, full accent color is scarce; reserve it for the single most important task, not decorative icons, borders, or every card. See references/color.md.

Changes

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.
