Summary

  • Add Gemini CLI tool support similar to Claude Code CLI, Agent CLI, OpenCode CLI, Codex CLI
  • Implement both JavaScript and Rust versions for consistency with existing tools
  • Add manual E2E test workflow for testing with real Gemini CLI
  • Restructure Rust tests to separate files (like JavaScript) for better organization

Implementation Details

JavaScript (js/src/tools/gemini.mjs)

  • Model mapping for Gemini models (flash, pro, lite, 3-flash, 3-pro variants)
  • Build arguments support: prompt, model, yolo (auto-approve), sandbox, debug, checkpointing, json output
  • NDJSON output parsing for stream-json format
  • Session/conversation ID extraction
  • Usage statistics extraction (standard and Gemini-specific formats)
  • Error detection

Rust (rust/src/tools/gemini.rs)

  • Parallel implementation with JavaScript for consistency
  • GeminiBuildOptions, GeminiUsage, GeminiErrorResult structs
  • GeminiTool struct implementing the Tool trait
  • Full test coverage

E2E Testing (e2e-gemini.yml)

  • Manual workflow for testing with real Gemini CLI (free tier)
  • Configurable model selection (flash, pro, 3-flash)
  • Custom test prompts and verbose mode
  • Tests both JavaScript and Rust implementations
  • Graceful handling when API keys or Gemini CLI unavailable

Test Structure Improvements

  • Moved all Rust tests from embedded #[cfg(test)] modules to separate files in rust/tests/:
    • claude_tests.rs (20 tests)
    • gemini_tests.rs (25 tests)
    • agent_tests.rs (18 tests)
    • codex_tests.rs (15 tests)
    • opencode_tests.rs (13 tests)
    • tools_tests.rs (12 tests)
    • streaming_tests.rs (17 tests)
    • lib_tests.rs (10 tests)
  • This matches the JavaScript test structure in js/test/*.test.mjs

Model Mappings

Alias Full Model ID
flash gemini-2.5-flash
pro gemini-2.5-pro
lite gemini-2.5-flash-lite
3-flash gemini-3-flash-preview
3-pro gemini-3-pro-preview

Tool Features

Feature Support
JSON output ✅ (stream-json)
JSON input ❌
System prompt ❌ (combined with user prompt)
Resume ✅ (via /chat resume)
Yolo mode ✅ (--yolo)
Sandbox ✅ (--sandbox)
Checkpointing ✅ (--checkpointing)
Debug ✅ (-d)

Test Plan

  • JavaScript tests pass (117 tests)
  • Rust tests pass (173 tests total: 43 unit + 130 integration)
  • Rust tests moved to separate files matching JS structure
  • ESLint passes (only pre-existing warnings)
  • Rust Clippy passes
  • Rust fmt check passes
  • Code duplication check passes
  • Prettier format check passes
  • Manual E2E workflow added for real CLI testing

E2E Testing Instructions

To run E2E tests with Gemini CLI:

  1. Add GEMINI_API_KEY or GOOGLE_API_KEY to repository secrets
  2. Go to Actions → "E2E Gemini CLI Test" workflow
  3. Click "Run workflow" and configure:
    • Model: flash (default), pro, or 3-flash
    • Test prompt: Custom prompt or use default
    • Enable/disable JS and Rust tests
    • Verbose mode for detailed output

Fixes #13

We should also check if link-assistant/hive-mind#559 has any useful ideas for that implementation.

Double check we do unit test everything we, can and it is executed in CI/CD. Also please add support for manual e2e tests (meaning it should be separate manually executed CI workflow) using free plan of Gemini CLI.

Both JavaScript and Rust versions must be implemented, have all the same tess. Make sure all our tests in Rust are in separate files, not mixed with code, like we do in JavaScript.

Also ensure all changes are correct, consistent and fully meet original requirements.
