    Quick Answer: Top 3 by installs, all free on Agensi: code-reviewer (764 installs), git-commit-writer (232), readme-generator (171). OpenCode reads SKILL.md skills from ~/.opencode/skills/. The 8 skills below all install cleanly there and are free on the Agensi marketplace: code-reviewer, git-commit-writer, readme-generator, pr-description-writer, prompt-engineer, env-doctor, codex-grade-coding, and skill-creator.

    OpenCode emerged in 2026 as a lightweight alternative to Claude Code for developers who want full agent capabilities without vendor lock-in. It's open-source, runs in your terminal, and supports the SKILL.md standard.

    The key difference from Claude Code: OpenCode works with any LLM provider. You can use OpenAI, Anthropic, Google, Mistral, or local models. You bring your own API key and pay only for tokens at the provider's rate with zero markup.

    Where OpenCode stores skills

    Project skills: .opencode/skills/ in your repository root.

    Personal skills: ~/.opencode/skills/ in your home directory.

    The format is identical to Claude Code. A folder containing a SKILL.md file with YAML frontmatter and markdown instructions. Skills written for Claude Code work in OpenCode without modification.

    How to install skills

    Download any SKILL.md skill and place it in the skills directory:

    # From Agensi
    unzip skill-name.zip -d ~/.opencode/skills/
    
    # From GitHub
    git clone https://github.com/user/skill-name ~/.opencode/skills/skill-name
    

    Restart your OpenCode session. The skill loads automatically when your task matches the skill's description.

    Best skills for OpenCode users

    OpenCode users tend to be cost-conscious developers. The most valuable skills reduce token consumption and produce correct output on the first try:

    Code review skills catch issues before they become expensive debugging sessions. Essential for any agent, especially one running on a pay-per-token model.

    Testing skills eliminate the generate-review-regenerate cycle. The right test on the first attempt saves tokens and time.

    Architecture skills for your specific stack prevent OpenCode from inventing abstractions you'll ask it to rewrite.

    OpenCode sits between Aider (minimal, git-focused) and Claude Code (full-featured, Anthropic-only). It offers SKILL.md support with model flexibility.

    Notes on OpenCode compatibility

    OpenCode implements the SKILL.md spec described in our format reference. Anything that runs in Claude Code with just SKILL.md and no Anthropic-specific tool calls will run in OpenCode.
