Gemini CLI Delegation

Overview

This skill implements conjure:delegation-core for the Gemini CLI. It provides Gemini-specific authentication, quota management, and command construction.

For shared delegation patterns, see Skill(conjure:delegation-core).

When To Use

• After Skill(conjure:delegation-core) determines Gemini is suitable
• When you need Gemini's large context window (1M+ tokens)
• For batch processing, summarization, or pattern extraction tasks
• If the gemini CLI is installed and authenticated

When NOT To Use

• Choosing which provider to delegate to (use conjure:delegation-core)
• Qwen was the selected provider (use conjure:qwen-delegation)

Prerequisites

Installation:

# Verify installation
gemini --version

# Check authentication
gemini auth status

# Login if needed
gemini auth login

# Or set API key
export GEMINI_API_KEY="your-key"

Verification: Run the command with --help flag to verify availability.

Quick Start

Basic Command

# File analysis
gemini -p "@path/to/file Analyze this code"

# Multiple files
gemini -p "@src/**/*.py Summarize these files"

# With specific model
gemini --model gemini-3-pro -p "..."

# JSON output
gemini --output-format json -p "..."

Save Output

gemini -p "..." > delegations/gemini/$(date +%Y%m%d_%H%M%S).md

Gemini-Specific Details

For Gemini-specific models, CLI options, cost reference, and troubleshooting, see modules/gemini-specifics.md.

Exit Criteria

• gemini --version exits 0 before any task is delegated, and a missing installation is reported and stops execution.
• Authentication is judged from GEMINI_API_KEY and from the delegation's own exit code, never from gemini auth status. That command exits 0 while printing Error authenticating: ProjectIdRequiredError over a credential that cannot be used, so its status is not evidence. delegation-core's shared module states the rule: authentication is never decided by running a provider's own CLI.
• The delegated task output is saved to delegations/gemini/YYYYMMDD_HHMMSS.md (timestamp format matching the Quick Start example), and that file exists on disk after the delegation completes.
• If conjure:delegation-core selected a different provider (Qwen or local), this skill is not invoked; Gemini delegation only runs when delegation-core explicitly routes to Gemini.
• Tasks requiring > 1M tokens in context are flagged before submission; the skill reports the estimated token count and confirms it falls within Gemini's supported window.
