Gemini CLI

Google’s open-source Gemini CLI supports the Agent Skills spec at .gemini/skills/.

Quick install

pnpm dlx @zakelfassi/skdd init --harness=gemini

That writes skills/skillforge/SKILL.md as the canonical source, .gemini/skills → ../skills as the mirror Gemini CLI actually reads, .skills-registry.md, and the skills block in AGENTS.md.

Configure

Gemini CLI reads AGENTS.md. The skills block (auto-written by skdd init) references skills/ as canonical and .gemini/skills as the mirror maintained by skdd link. See docs/configuration.md#gemini-cli for the exact text.

Verify

Run gemini in the project directory and ask “What skills are available?” → “Forge a skill for publishing release notes.” → reopen → confirm persistence.

Harness notes

• Gemini CLI honors nested skill discovery in monorepos the same way Claude Code does.
• The CLI is open-source at github.com/GoogleCloudPlatform/generative-ai-cli and ships under Apache-2.0.
• See geminicli.com/docs/cli/skills/ for the canonical skills docs.

Troubleshooting

Same failure modes as Claude Code (agent doesn’t scan registry → check AGENTS.md; skill doesn’t land → re-prompt to update the registry). Cross-reference docs/integrations/claude-code.md#troubleshooting.
