// Delegate tasks to Gemini CLI as an agent. Use when the user wants to offload token-heavy work to Gemini, get a second opinion from a different model, or run Gemini with a custom system prompt. Triggers include "use Gemini to review X", "ask Gemini to Y", "run Gemini on Z", "delegate to Gemini", "have Gemini check X".
End-to-end orchestrator for multi-task parallel work. Phase 1 (setup) gathers code intelligence, analyzes merge-conflict risks, groups tasks into maximally-parallel phases, writes enriched self-contained agent prompts, and generates PLAN.md + STATE.md. Phase 2 (execution) dispatches Opus agents in worktrees with a per-task review-gauntlet sub-skill pass and auto-fix commits, then a doc-update agent at completion. Asks explicit permission before starting autonomous execution. Resilient to /clear via file-backed state. Triggers on /parallel-phases, "parallelize these tasks", "run these in parallel phases".
Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior

Delegates tasks to Gemini CLI in headless mode using gemini_interface.py from this skill's scripts/ folder.
Prerequisite: Gemini CLI must be installed and on PATH (gemini --version should work).
python ~/.claude/skills/gemini-agent/scripts/gemini_interface.py \
--prompt "<task prompt>" \
--cwd "$(pwd)"
Pass any markdown file as a persona/role for Gemini. YAML frontmatter is stripped automatically.
python ~/.claude/skills/gemini-agent/scripts/gemini_interface.py \
--prompt "<task prompt>" \
--system-md /path/to/persona.md \
--cwd "$(pwd)"
If you need Gemini to read a large existing file, attach it via the --context-file argument (which uses Gemini's @file syntax under the hood):
python ~/.claude/skills/gemini-agent/scripts/gemini_interface.py \
--prompt "Review this file for security vulnerabilities." \
--context-file src/auth/login.py \
--cwd "$(pwd)"
Note: For short context or summaries (a few sentences), do not create a temp file. Just include the context directly inside your --prompt string!
| Flag | Default | Description |
|---|---|---|
--prompt | required | Task prompt |
--system-md | none | Markdown file prepended as system instructions |
--context-file | none | File attached via @path in the prompt |
--cwd | current dir | Working directory for Gemini CLI |
--model | gemini-3.1-pro-preview | Gemini model ID |
--verbose | off | Stream all output; default is final response only |
# Launch as a background task so Claude can continue working in parallel
Bash("python ~/.claude/skills/gemini-agent/scripts/gemini_interface.py --prompt '...' --cwd $(pwd)", run_in_background=true)
Gemini has no conversation context. Include everything it needs:
