skills: Instructions file for Codex

AGENTS.md

skills AGENTS.md is an instructions file for Codex, OpenCode from kurrent-io/skills. It costs 6,038 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for maintaining KurrentDB-related coding-agent skills. KurrentDB is a database built around event sourcing, a way of storing changes as a sequence of events rather than only the latest state.

In plain words
What is it for?
Use them when editing KurrentDB skills, migration agents, plugin manifests, marketplace entries, or related documentation.
Why use it?
They explain the required repository structure, plugin manifests, marketplace locations, and editing conventions so changes work across supported agent tools.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions Claude Code; mentions AGENTS.md.

This is kurrent-io/skills's own configuration. It tells Codex and OpenCode how to work on skills 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 skills configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is --skill-path ../plugins/kurrent/skills/kurrent-docs \.

Borrowing it

Nothing to install: this file belongs to kurrent-io/skills. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

skills 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.

AGENTS.md - Guidelines for AI Agents

This repository contains Agent Skills for working with KurrentDB and its ecosystem — server operations, client SDKs, connectors, Kurrent Cloud, the esc CLI, upgrades and migrations, and event-sourcing best practices. These guidelines help AI coding agents edit and maintain these skills effectively.

Repository Structure

This repo ships a single plugin, kurrent, under plugins/kurrent/ (not at the repo root). The plugin directory holds the skills, the migration orchestration agents, the plugin-level assets, and the per-ecosystem plugin manifests (.claude-plugin/plugin.json, .cursor-plugin/plugin.json, .codex-plugin/plugin.json, and plugin.json for Copilot). The marketplace catalogs stay at the repo root and point their source at ./plugins/kurrent. The plugin lives in a subdirectory rather than the repo root because Codex (codex issue #17066) rejects a plugin whose source.path resolves to the marketplace root; a subdirectory keeps every harness on a non-root source.

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.
