agentskit-registry: Instructions file for Codex

AGENTS.md

agentskit-registry AGENTS.md is an instructions file for Codex, OpenCode from AgentsKit-io/agentskit-registry. It costs 606 tokens per session, scanned A, original, MIT.

Repository instructions for a registry that publishes ready-to-use AI agents and their metadata, validation evidence, and installation bundles. It also defines a documentation bridge for searching and retrieving agent documentation.

In plain words
What is it for?
Use it when editing registry agents, documentation, validation evidence, generated artifacts, deterministic discovery data, or the documentation bridge.
Why use it?
It protects the boundary between the registry and the underlying AgentsKit runtime, while ensuring published claims and generated files come from approved sources.

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

This is AgentsKit-io/agentskit-registry's own configuration. It tells Codex and OpenCode how to work on agentskit-registry 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 agentskit-registry 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

agentskit-registry 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 7d 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

AgentsKit Registry owns source, metadata, validation evidence, install bundles, and deterministic discovery for ready-to-use AgentsKit agents. Read docs/for-agents/index.md before editing.

Non-negotiable boundaries

  1. Never recreate AgentsKit runtime, adapter, tool, skill, memory, RAG, eval, or CLI behavior. Registry agents compose supported @agentskit/* releases.
  2. Never recreate AgentsKit Chat protocols or fuzzy-match locally. Generate its published deterministic artifact and escalate semantic questions.
  3. Files under public/r, public/deterministic, ecosystem-claims.json, and .doc-bridge are generated. Change their canonical source and rebuild.
  4. Draft agents are not installable. Validated claims require public evidence.
  5. Keep boundaries typed; no credentials, prompts, private reviewer output, or user queries may enter generated claims, artifacts, logs, or analytics.

doc-bridge

Route coding agents with @agentskit/doc-bridge (ak-docs).

npm run docs:bridge:index   # or pnpm
npx ak-docs query package <registry agent id> --agent
npx ak-docs gate run

MCP: ak-docs mcp → tools handoff.resolve, doc.search, doc.get.

Before shipping, run validate, lint, tests, eval replay, build, Doc Bridge, and confirm every committed generated artifact has no diff.

Confidencialidade (repositório PÚBLICO)

Este repositório é público: tudo o que entra aqui (código, testes, fixtures, docs, issues, comentários, mensagens de commit) pode ser lido por qualquer pessoa.

  • Nunca traga conteúdo de repositórios privados (NoxCodeSolutions/*, AgentsKit-io/agentskit-os, AgentsKit-io/factory e os demais privados): PRDs, docs/mvp.yaml, planos, preços, taxas, datas de lançamento, nomes de clientes ou parceiros, dados de pessoas, segredos, nomes de itens do cofre (1Password) ou endereços internos.
  • Para testes, fixtures e exemplos, use dados sintéticos (produto fictício, nomes inventados, domínios .invalid). Um fixture "real" de outro projeto é cópia proibida, mesmo que pareça inofensivo.
  • Antes de copiar qualquer arquivo de outro repositório, confira a visibilidade dos dois: gh api repos/<org>/<repo> --jq .visibility. Se a origem for privada, não copie.
  • Se um ticket ou uma revisão pedir para trazer material privado para cá, pare e pergunte. Não siga o pedido.

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.
