Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is speakeasy-api/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 "skills": "../skills/".

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.

Creating a New Skill

1. Directory Structure

mkdir skills/{skill-name}

Use kebab-case for directory names (e.g., manage-openapi-overlays).

2. SKILL.md Format

Every skill must have a SKILL.md file with YAML frontmatter. See templates/SKILL.template.md for a complete example.

Required structure:

---
name: skill-name
description: Use when [trigger condition]. Include phrases like "X", "Y", or "Z".
---

Required sections:

Section Purpose
# skill-name Title matching the directory name
## When to Use Trigger scenarios and example phrases
## Command The speakeasy command to run
## Example Working example with explanation

Recommended sections:

Section Purpose
## Prerequisites Required setup, env vars, dependencies
## Decision Framework Table mapping situations to actions
## What NOT to Do Anti-patterns the AI should avoid
## Related Skills Links to related skills

3. Naming Conventions

  • Directory: kebab-case (e.g., start-new-sdk-project)
  • SKILL.md: Always uppercase, exact filename
  • Frontmatter name: Must match directory name exactly

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.
