ai-prompts: Instructions file for Codex

AGENTS.md

ai-prompts AGENTS.md is an instructions file for Codex, OpenCode from liatrio-labs/ai-prompts. It costs 283 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for creating and maintaining AI-agent skills, which are reusable instruction packages for coding agents. They define a required response marker, local setup scripts, a standard workflow and a check for documentation drift.

In plain words
What is it for?
Use them when adding or updating a skill, generating its OpenAI metadata file, validating it, or checking that repository documentation is current.
Why use it?
They give contributors one repeatable way to scaffold, update and validate skills. They also help keep the documented skill list aligned with the actual folders.

Instructions file for CodexOpenCode

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

This is liatrio-labs/ai-prompts's own configuration. It tells Codex and OpenCode how to work on ai-prompts 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 ai-prompts 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

ai-prompts 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 9d 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.

Local Skill Scripts

Use these local scripts when creating or updating skills in this repository.

Prefer running commands from the repository root with uv run.

Standard Workflow

  1. Initialize a skill scaffold.
  2. Update SKILL.md and any skill resources.
  3. Generate or refresh agents/openai.yaml when needed.
  4. Validate the skill folder.
# Initialize
uv run scripts/init_skill.py my-skill --path skills --resources scripts,references --examples

# Generate/refresh agents/openai.yaml
uv run scripts/generate_openai_yaml.py skills/my-skill

# Validate
uv run scripts/quick_validate.py skills/my-skill

If validation reports Description must be a string, got list, update the description: value in SKILL.md frontmatter to a quoted YAML string.

Documentation Drift Guardrail

Treat skills/*/SKILL.md as the canonical source for skill inventory.

When adding, removing, or renaming skills, keep repository docs in sync and run:

python scripts/check_docs_drift.py
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.
