gmx-ai: Instructions file for Codex

AGENTS.md

gmx-ai AGENTS.md is an instructions file for Codex, OpenCode from gmx-io/gmx-ai. It costs 138 tokens per session, scanned A, original, MIT.

A repository instruction file for gmx-ai that tracks skill files copied into three locations: web discovery, direct installation, and a Claude Code plugin marketplace. It lists the currently maintained trading-related skills.

In plain words
What is it for?
Use it when adding or modifying gmx-trading, gmx-liquidity, or other skills, so the matching files are updated in all three directories.
Why use it?
It prevents a change to one skill from leaving the other copies out of sync. This keeps the same instructions available through each supported distribution path.

Instructions file for CodexOpenCode

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

This is gmx-io/gmx-ai's own configuration. It tells Codex and OpenCode how to work on gmx-ai 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 gmx-ai 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

gmx-ai 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 6d 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.

Skill File Synchronization

Skill files are duplicated across three directories for compatibility with different indexing systems:

Directory Purpose
.well-known/skills/ Web-based skill discovery (well-known URI)
skills/ Direct skill installation (npx skills add)
plugins/gmx-io/skills/ Claude Code plugin marketplace

When modifying any skill file, apply the same change to all three locations.

Current skills

  • gmx-trading/ — SKILL.md + references/
  • gmx-liquidity/ — SKILL.md + references/
Changes

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.
