Main Agents: Do NOT use this skill directly. If you need to test the TUI, invoke the `tui_tester` subagent. Drive terminal UI (TUI) applications programmatically for testing, automation, and inspection. Use when: automating CLI/TUI interactions, regression testing terminal apps, or verifying interactive behavior. Also use when: user asks "what is agent-tui", "what does agent-tui do", "demo agent-tui", "show me agent-tui", "how does agent-tui work", or wants to see it in action.

Trigger this skill when the user wants to start an asynchronous PR review, run background checks on a PR, or check the status of a previously started async PR review.

Guidance for creating, running, fixing, and promoting behavioral evaluations. Use when verifying agent decision logic, debugging failures, debugging prompt steering, or adding workspace regression tests.

A specialized skill for Gemini CLI that provides high-performance, fail-fast monitoring of GitHub Actions workflows and automated local verification of CI failures. It handles run discovery automatically—simply provide the branch name.

Generates and formats changelog files for a new release based on provided version and raw changelog data.

Always use this skill when the task involves writing, reviewing, or editing files in the `/docs` directory or any `.md` files in the repository.

Use this skill when asked to create a GitHub issue. It handles different issue types (bug, feature, etc.) using repository templates and ensures proper labeling.

Use this skill if the user asks you to help them address GitHub PR comments for their current branch of the Gemini CLI. Requires `gh` CLI tool.

Use this skill when asked to create a pull request (PR). It ensures all PRs follow the repository's established templates and standards.

Use this skill during code reviews to proactively investigate the codebase for duplicated functionality, reinvented wheels, or failure to reuse existing project best practices and shared utilities.

Use this skill when asked to review text and user-facing strings within the codebase. It ensures that these strings follow rules on clarity, usefulness, brevity and style.

Expert guidance for testing Gemini CLI behavior and visual output using terminal automation.

A friendly greeter skill

Use when the user asks questions, seeks help, or requests instructions related to installing, setting up, or migrating to Antigravity CLI. This skill provides the latest up to date details, requirements, and commands sourced from the official Antigravity CLI documentation.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Gemini CLI's capabilities with specialized knowledge, workflows, or tool integrations.

Estimates the implementation effort required to address the given issue.

Evaluates whether a GitHub issue is spam, empty, needs more information, or is OK to proceed.

Expertise in auditing and fixing repository scripts and GitHub Actions workflows to ensure technical robustness and security.

Expertise in maintaining persistent bot memory, synchronizing with previous sessions via the Task Ledger, and preserving decision logs.

Expertise in analyzing time-series repository health metrics, investigating root causes, and proposing proactive workflow improvements.

Expertise in managing the Git and GitHub Pull Request lifecycle, including staging changes, generating PR descriptions, and branch management.

Mix speech audio and background music into a polished radio show file.

Generate cover images for the radio show using Gemini 3 Flash Image (with fallback to Pro).

Generate show metadata (JSON) containing timecoded transcript, title, duration, summary, and date by sending audio and transcript to Gemini.

Generate ambient background music using Lyria via the Interactions API.

Gather source material for the radio show from any content source — web, HN, GitHub, papers, or general topics.

Generate the AI Talk Radio show script from research using the Interactions API.

Convert radio show script to speech audio with telephone effect on correspondent voices using the Interactions API.

Records and appends every user-agent customer support interaction to the memory.md log in the workspace.

Scans a website deeply, converting HTML pages to markdown, respecting robots.txt, and updating the snapshots log.

General-purpose data profiling and exploration. Use when first encountering any dataset to understand its structure, quality, and analysis potential.

Performs heavy numerical compute and statistical analysis inside the sandbox.

Exposes a 100% local, offline PDF batch extraction utility (extract_to_markdown.py) that isolates invoices under invoices/ and translates PDFs into clean Markdown files for LLM-native parsing.

Reconcile loaded expenses against the pre-parsed invoice database, flagging discrepancies like amount mismatches, missing invoices, and merchant mismatches locally.

Create Google-style presentation slides as standalone HTML files. Use when the user wants to (1) create presentation slides from notes or bullet points, (2) build slide decks in HTML format, (3) recreate or replicate existing slide designs, (4) convert rough notes or talking points into polished visual slides, or (5) needs professional Google-branded presentation materials with clean typography, visual diagrams, code blocks, or data visualizations.

Verify whether vendors/merchants from expense records are real, registered business entities by querying the free Wikidata open API.

Formats the standalone daily briefing — curated picks with why-it-matters lines, community buzz, the trend read across runs, and the taste note that keeps the learning visible.

Selection and ranking rules — how to turn the raw fetched pool into the handful of items the reader actually wants, guided by the taste profile in interests.json.

Posts a condensed version of the briefing to a Google Chat or Slack incoming webhook, so the daily run delivers itself — skips silently when no webhook is configured.

Pulls the latest Google News and Hacker News items for every topic and genre in the reader's interests, deduped against every item shown in previous runs.

Guides the agent on how to handle git operations and generate .patch files instead of submitting PRs.

Guides the agent on how to read and search GitHub issues to understand the repository's problems.

Use this skill when building applications with Gemini API hosted models, including Gemini and Gemma 4, working with multimodal content (text, images, audio, video), implementing function calling, using structured outputs, or needing current model specifications. Covers SDK usage (google-genai for Python, @google/genai for JavaScript/TypeScript, com.google.genai:google-genai for Java, google.golang.org/genai for Go), model selection, and API capabilities.

Use this skill when writing code that calls the Gemini API for text generation, multi-turn chat, multimodal understanding, image generation, video generation, streaming responses, background research tasks, function calling, structured output, or migrating from the old generateContent API. This skill covers the Interactions API, the recommended way to use Gemini models and agents in Python and TypeScript.

Use this skill when building real-time, bidirectional streaming applications with the Gemini Live API. Covers WebSocket-based audio/video/text streaming, voice activity detection (VAD), native audio features, function calling, session management, ephemeral tokens for client-side auth, live translation, and all Live API configuration options. SDKs covered - google-genai (Python), @google/genai (JavaScript/TypeScript).

Use this skill for generative video editing, text-to-video, image-referenced video generation, and first-frame-to-video transition animations using the official google-genai SDK. Includes workflows for pre-processing/optimizing high-resolution or long source videos with ffmpeg, stripping audio for full sound regeneration, and handling turn-by-turn video editing and parallel execution.

Guide for using the Gemini API CLI tool. Use when you need to interact with the Gemini API via the command line, manage agents, or generate media (images, audio).
