design-engineering AGENTS.md

Repository instructions for a design-engineering project: a collection of guidance, supporting files, workflow agents, commands, and package files for building digital interfaces.

In plain words
What is it for?
Use it when editing the design-engineering repository, especially its skills, reference material, agents, commands, or plugin files.
Why use it?
It gives coding agents the project's rules, structure, and sources of truth so changes fit the existing design system and packaging.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

design-engineering 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.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Repo-level operating guidance for AI agents working in this codebase. Pairs with SOUL.md, which carries identity (voice, stance, taste lineage). This file is the what / how; SOUL.md is the who / why. Read both on cold start.

What this repo is

A single agent skill packaged as a skill graph — one root SKILL.md (the Map of Content) plus a references/ folder of atomic, wikilinked nodes organised into themed subfolders (philosophy/, motion/, typography/, surface/, components/, layout/, anti-patterns/, meta/) and an evals/ folder for Perplexity-style Step-0 evals. A sibling agents/ directory ships six workflow subagents that map to the highest-value design-engineering tasks. The skill encodes design engineering knowledge.

Since v2.0.0 the repo is organised around four primitives: Knowledge (skills/design-engineering/, Agent Skills spec), Package (root plugin.json, Agent Plugins v1.0.0), Runtime (agent/ + evals/, the eve framework), and Client extensions (agents/, commands/, and the per-host manifest dirs, declared under reverse-domain namespaces in plugin.json extensions). The knowledge is canonical; everything else delivers it. agent/skills/ is generated by scripts/sync-skills.mjs — never edit it; edit skills/design-engineering/ and re-sync.

The graph is intentionally Obsidian-compatible: installers can open this repo as a vault to navigate clusters in the graph view and edit nodes in place. The recommended companion is kepano/obsidian-skills. Preserving that compatibility is a constraint on every edit (see rule 6).

When editing this repo

1. Edit atomic nodes, not the SKILL.md. The SKILL.md is a map. Real content lives in references/<theme>/. If you're adding new knowledge, drop the atomic node into the matching themed subfolder and link it from that theme's MOC-<theme>.md. Only update SKILL.md when adding a new top-level topic (which means adding a whole new theme folder).

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.

design-engineering AGENTS.md is an instructions file published in the GitHub repository AgentsORG/design-engineering (21 stars, last pushed 10d ago), licensed MIT. It adds 3,091 tokens to every session, about $0.0155 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
