+
+# Ask Gemini (Local CLI)
+
+Use the locally installed Gemini CLI as a direct external advisor for brainstorming, design feedback, and second opinions.
+
+## Usage
+
+```bash
+/ask-gemini <question or task>
+```
+
+## Routing
+
+### Preferred: Local CLI execution
+Run Gemini through the canonical OMX CLI command path (no MCP routing):
+
+```bash
+omx ask gemini "{{ARGUMENTS}}"
+```
+
+Exact non-interactive Gemini CLI command from `gemini --help`:
+
+```bash
+gemini -p "{{ARGUMENTS}}"
+# equivalent: gemini --prompt "{{ARGUMENTS}}"
+```
+
+If needed, adapt to the user's installed Gemini CLI variant while keeping local execution as the default path.
+
+Legacy compatibility entrypoints (`./scripts/ask-gemini.sh`, `npm run ask:gemini -- ...`) are transitional wrappers.
+
+### Missing binary behavior
+If `gemini` is not found, do **not** switch to MCP.
+Instead:
+1. Explain that local Gemini CLI is required for this skill.
+2. Ask the user to install/configure Gemini CLI.
+3. Provide a quick verification command:
+
+```bash
+gemini --version
+```
+
+## Artifact requirement
+After local execution, save a markdown artifact to:
+
+```text
+.omx/artifacts/gemini-<slug>-<timestamp>.md
+```
+
+Minimum artifact sections:
+1. Original user task
+2. Final prompt sent to Gemini CLI
+3. Gemini output (raw)
+4. Concise summary
+5. Action items / next steps
+
+Task: {{ARGUMENTS}}
