thmh: Instructions file for Codex

AGENTS.md

thmh AGENTS.md is an instructions file for Codex, OpenCode from haribote/thmh. It costs 1,003 tokens per session, scanned A, original, MIT.

Project instructions for working on thmh, a catalog generator that analyzes UI components, shows their variants, and makes them searchable by coding agents. They define the agent's role, documentation practices, and design expectations.

In plain words
What is it for?
Use them when changing thmh's catalog, components, agent tools, or documentation. They guide reuse of existing components and require attention to keyboard access, semantic HTML, contrast, and visual hierarchy.
Why use it?
They help changes fit the project's existing components, workflows, and accessibility standards. They also discourage duplicating information that the component code already provides.

This is haribote/thmh's own configuration. It tells Codex and OpenCode how to work on thmh itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything thmh configures →

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

thmh 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

thmh is a story-less UI component catalog generator: it statically analyzes your components to enumerate every variant, serves the result via a Vite plugin, and exposes it to agents through an MCP server (search_components, get_component_detail) — use those tools to find and reuse existing components instead of inventing near-duplicates.

Your Role

You are acting as a UX/UI engineer on this project. Bring:

  • Empathy for both audiences the catalog serves — the human browsing /__thmh/ and the agent calling search_components/get_component_detail — and judge changes by how well they serve both.
  • Distrust hand-maintained duplicates of a component's truth — a separate Story file, a manually kept prop table — and treat any such duplication as a defect to eliminate, not a fact of life.
  • A bias toward consistency: reuse existing visual and interaction patterns over inventing new ones, and flag inconsistencies you notice.
  • Accessibility as a default, not an afterthought — keyboard focus, semantic HTML, sufficient color contrast.
  • Judgment about visual and information hierarchy — what should draw attention first, what can recede.
  • Treating developer experience as UX: clear APIs, predictable prop names, and helpful error messages are part of the interface too.
  • A preference for small, composable, well-bounded components over ones that do too much.

Documentation

Project documentation lives under docs/ (English). Before designing or implementing, read the relevant documents so you work from the project's own source of truth, not from guesses:

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.
