gemini-skill-install 0.1.5

Bootstrap installer for the gemini Claude Code skill

gemini-skill

gemini-skill is a Gemini API front end that works in two modes:

• as a Claude Code skill via /gemini ...
• as a direct CLI via python3 scripts/gemini_run.py ...

It exposes the same command surface in both modes: text, multimodal analysis, structured output, embeddings, Files API, image/video/music generation, file search, deep research, and iterative plan review.

Quick Start

Install for Claude Code

Recommended:

uvx gemini-skill-install

Fallback:

uvx --python 3.13 gemini-skill-install

Or from a clone:

git clone https://github.com/reshinto/gemini-skill.git
cd gemini-skill
python3 setup/install.py

The installer copies the runtime payload into ~/.claude/skills/gemini/, creates or reuses ~/.claude/skills/gemini/.venv, installs the pinned google-genai SDK, and writes the canonical env block into ~/.claude/settings.json.

Configure credentials

Create a Gemini API key in Google AI Studio:

• Google AI Studio: https://aistudio.google.com/
• API key guide: https://ai.google.dev/gemini-api/docs/api-key

The Gemini API is not an unlimited flat-rate service. Google offers a free tier for getting started and a paid pay-as-you-go tier for higher-volume or production use. If you enable the paid tier, prompts and responses can incur usage-based charges depending on the model and features you use.

The launcher resolves canonical Gemini env keys from the current working directory first, then Claude settings files, then existing process env:

1. ./.env
2. ./.claude/settings.local.json
3. ./.claude/settings.json
4. ~/.claude/settings.json
5. existing process env

Supported keys:

GEMINI_API_KEY
GEMINI_IS_SDK_PRIORITY
GEMINI_IS_RAWHTTP_PRIORITY
GEMINI_LIVE_TESTS

For repo-local CLI use:

cp .env.example .env

GEMINI_API_KEY is the only supported secret name. GOOGLE_API_KEY is ignored.

Use it from Claude Code

The skill manifest sets disable-model-invocation: true, so Claude Code will not start this skill on its own. Invoke it explicitly first.

/gemini text "Explain quantum computing in three sentences"
/gemini plan_review "Review this implementation plan for gaps and rollout risks"

Use it as a direct CLI

From a checkout:

python3 scripts/gemini_run.py text "hi"
python3 scripts/gemini_run.py plan_review "Review this migration plan"
python3 scripts/gemini_run.py plan_review

The last command starts the interactive plan_review REPL when stdin is a TTY.

Core Workflows

• text for one-shot prompts and multi-turn sessions
• plan_review for iterative plan review, either one-turn or REPL
• multimodal for PDFs, images, audio, video, and URLs
• structured for schema-constrained JSON output
• embed, token_count, files, cache, batch, and file_search
• image_gen, imagen, video_gen, and music_gen
• search, maps, computer_use, deep_research, and live

Documentation

• docs/install.md — install paths, env precedence, troubleshooting
• docs/usage.md — Claude Code skill usage and direct CLI usage
• docs/usage-tour.md — end-to-end examples
• docs/commands.md — command index by capability family
• reference/index.md — per-command reference pages
• docs/security.md — secrets handling, local data storage, privacy notes
• docs/how-it-works.md — launcher, dispatch, transport, and output flow
• docs/README.md — documentation hub

Backend Routing

The launcher and adapters are backend-agnostic. The transport coordinator chooses the SDK or raw HTTP backend from the two routing flags:

• GEMINI_IS_SDK_PRIORITY=true
• GEMINI_IS_RAWHTTP_PRIORITY=false

Both backends produce the same normalized response shape for callers.
