gemini-interactions-api is a skill for Codex from PracticalSwan/agent-skills. It costs 80 tokens per session (5,226 once invoked), scanned A, original, MIT.

A guide for writing applications with Google's Gemini API, a service for generating or understanding text and other media with AI models. It covers conversations, images, video, audio, structured responses, and tool calls.

In plain words
What is it for?
Use it to build text, multimodal, streaming, structured-output, function-calling, image, video, or audio features with Gemini.
Why use it?
It helps developers use the current API patterns correctly when building AI features or moving from older API methods.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

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.

Security

Grade A, and why

gemini-interactions-api 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 5d 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-3.1-pro-preview: 1M tokens, complex reasoning, coding, research
  • gemini-3.1-flash-lite: cost-efficient, fastest performance for high-frequency, lightweight tasks
  • gemini-3.5-transcribe: fast speech-to-text with smart and verbatim modes
  • gemini-3-pro-image (Nano Banana Pro): 65k / 32k tokens, high-quality image generation and editing

[!WARNING] Models like gemini-2.5-*, gemini-2.0-*, gemini-1.5-* are legacy and deprecated. Never use them. If a user asks for a deprecated model, use gemini-3.7-flash instead and note the substitution.

Current Agents

  • Managed-agent identifiers must come from current official documentation and the user's account; do not assume a provider-specific agent is exposed.
  • deep-research-preview-04-2026: Deep Research — fast, interactive
  • deep-research-max-preview-04-2026: Deep Research Max — maximum exhaustiveness
  • Custom agents: Create your own via client.agents.create()

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.
