armorial: Instructions file for Codex

AGENTS.md

armorial AGENTS.md is an instructions file for Codex, OpenCode from tetracoralla/armorial. It costs 476 tokens per session, scanned A, original, Apache-2.0.

A set of AGENTS.md instructions defining the rules for the armorial repository, which provides a design-system-aware icon selection system. AGENTS.md is a project file that tells coding agents how to work in that repository.

In plain words
What is it for?
Guiding reviews and implementation across the icon kernel, command-line interface, web UI, MCP adapters, and Figma integration.
Why use it?
It gives reviews and code changes a shared contract, including which source package to use and where selection and rendering logic belongs.

Instructions file for CodexOpenCode

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

This is tetracoralla/armorial's own configuration. It tells Codex and OpenCode how to work on armorial 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 armorial 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

armorial 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 1mo 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.

Working on Armorial

Armorial helps people and Agents choose existing icons and use them in a UI. Read the current request and affected implementation first. For product context, see docs/PRODUCT_MODEL.md. The review map in docs/REVIEW_CONTRACT.md points to useful checks; choose coverage from the change and the actual user flow.

Engineering boundaries

  • src/core/kernel.ts owns selection, search, policy, and rendering. Adapters translate CLI, MCP, browser, and Figma interactions into that shared behavior.
  • The current provider is pinned IconPark. Preserve its geometry and provenance when producing an Armorial asset; do not silently substitute another library.
  • Deterministic selection reports its basis and unresolved candidates. The caller can interpret the task, compare candidates, and choose an exact id. Engine ambiguity is not a requirement to ask the owner about ordinary design.
  • Appearance overrides layer over project defaults/context and report overridden when they change policy values. Output is bounded, deterministic, and free of scripts, external references, and event handlers.
  • MCP inputs are closed domain data. Local file access belongs to CLI/server setup, not arbitrary paths or executable content in tool arguments.
  • Generate icon-policy.schema.json from IconPolicySchema; check schema drift.

Verification and records

Exercise the affected entry point and the result in its consumer. npm run check is the development regression suite; npm run ui:e2e covers browser interaction. Packaging changes need the matching package probe. A UI change needs rendered inspection as well as assertions. A discovery claim needs a fresh consumer task; explicit invocation alone proves only invocation.

Keep public documentation useful to users and contributors. Private plans, historical review transcripts, local captures, and handoffs belong in ignored .task-notes/. Preserve useful failure cases as executable tests or focused technical references, not accumulating mandatory procedures. Do not test that an Agent guide contains a prescribed phrase or thinking sequence.

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.
