google-gemini/gemini-skills is a collection of reusable skills that give coding agents context for the Gemini API, SDK, and model interactions. Developers use it when building applications powered by Gemini, and the catalogue entries are skills for those development workflows.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00110 | $0.04413 |
| Opus 5.5 | $0.00044 | $0.01765 |
| Sonnet 5.5 | $0.00022 | $0.00883 |
| Haiku 4.5 | $0.00011 | $0.00441 |
Grade A, and why
gemini-live-api-dev 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.

Gemini Live API Development Skill
Overview
The Live API enables low-latency, real-time voice and video interactions with Gemini over WebSockets. It processes continuous streams of audio, video, or text to deliver immediate, human-like spoken responses and background reasoning.
Key capabilities:
- Bidirectional audio streaming — real-time mic-to-speaker conversations
- Background reasoning (extended thinking) — multi-step background reasoning with spoken conversational fillers
- Live streaming transcription — real-time speech-to-text with interim and finalized streams
- Video streaming — send camera/screen frames alongside audio
- Text input/output — send and receive text within a live session
- Audio transcriptions — get text transcripts of both input and output audio
- Voice Activity Detection (VAD) — automatic server VAD, client-side Hybrid VAD, and manual Push-to-Talk
- Asynchronous function calling — non-blocking tool execution while audio continues streaming
- Full-session client content — inject and update conversation turns mid-stream
- Session management — context compression, session resumption, GoAway signals
- Ephemeral tokens — secure client-side authentication
[!NOTE] The Live API connects directly via WebSockets. For WebRTC support or simplified integration, use a partner integration.
Models
Current Models (Use These)
gemini-3.8-live— Default option for most low-latency voice agent experiences and real-time dialogue without reasoning delays. Supports interleaved reasoning, asynchronous function calling by default (behavior: NON_BLOCKING), and full-session client content updates.gemini-3.8-live-extended-thinking— High-reasoning audio-to-audio model recommended when higher background reasoning is required during live interactions. Processes background reasoning and async tool calls (behavior: NON_BLOCKINGrequired) while streaming continuous spoken conversational fillers; lifecycle managed viainteraction_status(IN_PROGRESSvsIDLE).gemini-3.5-transcribe-live— Real-time streaming speech-to-text with interim hypotheses, finalized transcripts, smart formatting, and Hybrid VAD.gemini-3.5-live-translate-preview— Real-time speech-to-speech streaming translation across 70+ languages.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gemini-live-api-dev is a skill published in the GitHub repository google-gemini/gemini-skills (4,282 stars, last pushed 2d ago), licensed Apache-2.0. It adds 110 tokens to every session and 4,413 once invoked, about $0.0004 per session on Opus 5.5. 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.
