Gemini API Dev is an agent skill from aiskillstore/marketplace. 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...
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).
It sits in AI & LLM Engineering, covering LLM API integration and Structured output and tool calling. It works with Google Gemini, Model Context Protocol, Java and Python. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified. The licence is Apache-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
pipnpmgoFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
ai.google.devAlso links to:
central.sonatype.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Gemini API Dev loads about 1.6k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 448 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Gemini API Dev is an agent skill from aiskillstore/marketplace. 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.
Gemini API Dev fits situations like: building applications with Gemini API hosted models; including Gemini and Gemma 4; working with multimodal content (text; implementing function calling.
Run `npx skills add aiskillstore/marketplace --skill gemini-api-dev -a claude-code`. Or copy the skill folder (skills/sickn33/gemini-api-dev in aiskillstore/marketplace) into .claude/skills/gemini-api-dev in your project. Claude Code loads it when a task matches its description.
Run `npx skills add aiskillstore/marketplace --skill gemini-api-dev -a codex`. Or copy the skill folder (skills/sickn33/gemini-api-dev in aiskillstore/marketplace) into .agents/skills/gemini-api-dev in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill gemini-api-dev -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gemini-api-dev, .gemini/skills/gemini-api-dev, .github/skills/gemini-api-dev and .opencode/skills/gemini-api-dev in your project.
Going by SKILL.md and its folder, Gemini API Dev needs the command-line tools its instructions call (pip, npm and go). Our summary lists: Python 3; Node.js.
SKILL.md names 2 domains. In commands or code: ai.google.dev; the agent is likely to contact it when it follows the instructions. As links in the text: central.sonatype.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Gemini API Dev is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Gemini API Dev: Gemini API Dev (Ayuilos/Miffan, 182 stars), Gemini API Dev (JetBrains/skills, 363 stars), Gemini Interactions API (Ayuilos/Miffan, 182 stars) and Gemini API Dev (google-gemini/gemini-skills, 4.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
