document-design-system: Instructions file for Codex

AGENTS.md

document-design-system AGENTS.md is an instructions file for Codex, OpenCode from Avinava/document-design-system. It costs 1,116 tokens per session, scanned A, original, MIT.

Repository instructions for a document design system: a set of rules for organizing documents and applying visual themes. They cover matching Markdown examples, HTML templates, scripts, and tests.

In plain words
What is it for?
Use them when editing document types, choosing a reading structure or theme, rebuilding examples, regenerating screenshots, and running validation.
Why use it?
They keep written examples and generated document designs consistent when the repository changes.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is Avinava/document-design-system's own configuration. It tells Codex and OpenCode how to work on document-design-system 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 document-design-system 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

document-design-system 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 9d 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.

Repository guidance

This repository treats document design as two independent axes:

  • Document pattern controls reading structure and is declared with data-pattern.
  • Theme controls visual voice through semantic tokens and is declared with data-theme.

Do not reduce the writing examples to one generic longform layout. Select one of the eleven patterns in core/document-patterns.md, then use the modules that support that reader movement. Keep prose readable at 62–72 characters while allowing maps, tables, comparisons, timelines, and registers to use the wider shell.

Markdown in examples/<slug>.md is the canonical repository-friendly form. Designed HTML is generated from templates/types/<slug>.html (presets) or templates/composed/<slug>.html (composed examples); both forms must use the same title and factual anchors from examples/WORLD.md.

Types, composition and promotion

A request that matches a type or one of its familiar names uses that type. When none fits, compose: pick the pattern by the reader's question (skills/writing-documents/references/type-index.md), use only the modules the registry in core/document-patterns.md allows for that pattern, and borrow the nearest type's section discipline (references/composing.md). Do not force the nearest preset, and do not add a type for a one-off request. A composed shape seen three times is promoted to a type; that is the only way the catalog grows.

The catalog is edited in one place. A type's slug, aliases, pattern and default-theme live only in its type-<slug>.md yaml block, and the families table in core/document-patterns.md lists it. scripts/catalog.py derives everything else — the build, the Patterns page, the site, the validator and the tests — from those files, the module registry, the reader-question table in type-index.md and the stages in consultancy-lifecycle.md. Gallery card copy lives in TYPE_QUESTIONS and COMPOSED_GALLERY in scripts/build_examples.py; the homepage story lives in STORY in scripts/build_site.py, with every date taken from the example it links to.

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.
