Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/livekit/agent-skills/agents-mdgit clone --depth 1 https://github.com/livekit/agent-skillsWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00494 | $0.00494 |
| Opus 5 | $0.00247 | $0.00247 |
| Sonnet 5 | $0.00099 | $0.00099 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
agent-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 2d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Contributing Guidelines
Skill Content Principles
All skills in this repository must follow the "freeze forever" principle:
- Encode behavior, not knowledge - Skills teach how to approach problems, not API specifics
- Direct to MCP for facts - All factual information must come from live documentation
- Require testing - Every agent implementation must include tests
- Stay under 500 lines - Keep skills concise for context efficiency
SKILL.md Format
Each skill requires YAML frontmatter:
---
name: skill-name-kebab-case
description: Trigger phrases and brief description. Include phrases like "build a voice agent" that help agents recognize when to use this skill.
license: MIT
metadata:
author: livekit
version: "X.Y.Z"
---
File Naming
- Skill directories use
kebab-case SKILL.mdis the only uppercase filename- Supporting docs go in
references/subdirectory
LiveKit MCP Server
These skills are designed to work with the LiveKit Docs MCP server. If you're working on this repository and need to test MCP integration, make sure it is installed. Installation instructions are available at https://docs.livekit.io/intro/mcp-server/

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.
- 2d ago First seen · 64 lines · 494 tokens per session scan A 7ca81b0c146e
agent-skills AGENTS.md is an instructions file published in the GitHub repository livekit/agent-skills (66 stars, last pushed 2mo ago), licensed MIT. It adds 494 tokens to every session, about $0.0025 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
