What it does
Gemini API Dev is an agent skill from JetBrains/skills, published by the product's own GitHub organization. Use this skill when building applications with Gemini models, Gemini API, 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.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering LLM API integration and Structured output and tool calling. It works with Google Gemini, Python, Java and JavaScript. The repository describes itself as: Curated agent skills collection verified by JetBrains.
When your agent uses it
- Building applications with Gemini models
- Working with multimodal content (text
- Implementing function calling
- Using structured outputs
Example prompts
- “/gemini-api-dev”
Requirements
- Python 3
- Node.js
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Fetch llms.txt to discover available documentation pages
- Fetch specific pages (e.g., https://ai.google.dev/gemini-api/docs/function-calling.md.txt)
What it can do on your machine
Read from SKILL.md and the folder at commit e0f258b. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Shell commands in SKILL.md call:
pipnpmgo
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
ai.google.devgenerativelanguage.googleapis.com
Also links to:
central.sonatype.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gemini API Dev loads about 1.6k tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 410 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.
Safety
Auto-check passed
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 410 words (~1,621 tokens).
“The Gemini API provides access to Google's most advanced AI models. Key capabilities include:”
