    Best Gemini CLI Skills in 2026 — Compatible SKILL.md Skills That Work

    The best SKILL.md skills for Google's Gemini CLI. Tested, security-scanned, and ready to install.

    Quick Answer: Gemini CLI supports SKILL.md files in ~/.gemini/skills/ (personal) and .gemini/skills/ (project). Every skill on Agensi works with Gemini CLI. Top picks: code-reviewer (447 installs), git-commit-writer (170 installs), env-doctor (86 installs). All free.

    Gemini CLI is Google's open-source terminal-based coding agent. It reads the same SKILL.md format used by Claude Code, Cursor, and Codex CLI. That means the entire Agensi catalog works in Gemini CLI without modification.

    Gemini CLI is newer than Claude Code and Cursor, so most skill creators haven't tested specifically against it. The skills below have been verified to work with Gemini CLI's skill loading system.

    Code review and quality

    code-reviewer (447 installs) is the most popular skill on Agensi. It reviews code for bugs, security vulnerabilities, performance issues, and style violations. Organizes findings by severity. Works identically in Gemini CLI as in Claude Code. Free.

    codex-grade-coding (37 installs) enforces strict task classification and verification-driven protocols. It slows the agent down to reduce errors, which is particularly useful with Gemini CLI's more aggressive generation style. Free.

    pr-description-writer (85 installs) writes pull request descriptions from your branch diff. Platform-agnostic — works with GitHub, GitLab, and Bitbucket. Free.

    Recommended skills

    Git automation

    git-commit-writer (170 installs) analyzes your staged changes and writes conventional commit messages. Detects commit type, scope, and breaking changes. Free.

    changelog-generator (41 installs) turns commit history into user-facing release notes. Free.

    Debugging and reliability

    env-doctor (86 installs) systematically diagnoses startup failures by checking runtime versions, dependencies, environment variables, databases, and ports. Free.

    truth-first (11 installs) forces evidence-first verification before the agent makes changes. Reduces hallucinations by requiring the agent to check file contents and system state before acting. Useful in Gemini CLI where the model can be confidently wrong. Free.

    lobster-debugging (6 installs) is a 4-phase debugging framework for finding root causes and eliminating flaky tests. Free.

    Documentation

    readme-generator (117 installs) scans your project and generates a complete README.md. Free.

    skill-polisher (13 installs) improves any markdown documentation. Not limited to skills. Free.

    How to install skills in Gemini CLI

    Place skills in ~/.gemini/skills/ for personal use or .gemini/skills/ in your project:

    │   └── SKILL.md
    ├── git-commit-writer/
    │   └── SKILL.md
