description	Internal helper contract for calling the gemini-companion runtime (which wraps Google's Antigravity CLI, `agy`) from Claude Code
user-invocable	false

agy Companion Runtime

Use this skill only inside the gemini:gemini-rescue subagent.

Primary helper:

• GEMINI_RESCUE_MODE=1 node "${CLAUDE_PLUGIN_ROOT}/scripts/companion.mjs" task "<raw arguments>"

The GEMINI_RESCUE_MODE=1 env var asks the companion runtime to apply a finite default timeout (15 min) to the task call. This is belt-and-suspenders with the prompt-level "always pass --timeout 15m" rule below: if a rephrased forwarded request somehow loses the flag, the runtime still enforces a deadline. Direct /gemini:task callers do not set the env var, so unbounded behavior is preserved for them.

Execution rules:

• The rescue subagent is a forwarder, not an orchestrator. Its only job is to invoke task once and return that stdout unchanged.
• Prefer the helper over hand-rolled git, direct agy invocations, or any other Bash activity.
• Do not call setup, review, adversarial-review, status, result, or cancel from gemini:gemini-rescue.
• Use task for every rescue request, including diagnosis, planning, research, and explicit fix requests.
• You may use the gemini-prompting skill to rewrite the user's request into a tighter agy prompt before the single task call.
• That prompt drafting is the only Claude-side work allowed. Do not inspect the repo, solve the task yourself, or add independent analysis outside the forwarded prompt text.
• Default to read-only agy behavior. Add --write ONLY when the user explicitly asks for code changes.
• --write is gated by GEMINI_PLUGIN_ALLOW_WRITE=1 in the environment. If the env var is missing the helper will refuse with exit 2 and a message explaining --dangerously-skip-permissions. Do not retry, do not try to set the env var yourself — surface the refusal to the user verbatim and let them decide.
• Leave --model unset by default. agy 1.0 binds its model internally and ignores --model, but the flag is still accepted on the companion's CLI for back-compat; passing it produces no behavioral change in agy. Only add --model <name> when the user explicitly requests one (purely informational).

Command selection:

• Use exactly one task invocation per rescue handoff.
• Run the Bash call in the foreground (do not set run_in_background: true). The rescue contract is synchronous: the parent agent expects agy's real answer, not a "running in background" stub from Claude Code's Bash tool. Issue #3 was caused by the previous "prefer background for long tasks" guidance, which made the wrapper forward a job-ID stub instead of agy's output. For genuinely long tasks, the user can call /gemini:task --background "..." directly from the main thread.
• If the forwarded request includes --background or --wait, treat that as Claude-side execution control only. Strip it before calling task, and do not treat it as part of the natural-language task text.
• If the forwarded request includes --write or --read-only, pass it through to task.
• Timeout policy for rescue: task's built-in default is unbounded, which is unsafe for rescue because the parent agent blocks on a single foreground call. If the forwarded request includes --timeout <duration>, pass it through verbatim. If it does NOT include --timeout, you MUST add --timeout 15m to the task call. This bounds rescue against a hung agy process indefinitely stranding the parent agent. Forms accepted: 300s, 5m, 1h, 500ms, or 0 to disable. Users who want unbounded rescue must pass --timeout 0 explicitly. On timeout the helper exits 124 — surface that to the user rather than retrying.
• Never call purge from this subagent. /gemini:purge is a destructive disk-cleanup operation the user invokes explicitly; rescue is forwarder-only.

Safety rules:

• Default to read-only agy work in gemini:gemini-rescue unless the user explicitly asks for code changes.
• Preserve the user's task text as-is apart from stripping routing flags.
• Do not inspect the repository, read files, grep, monitor progress, poll status, fetch results, cancel jobs, summarize output, or do any follow-up work of your own.
• Return the stdout of the task command exactly as-is.
• If the Bash call fails or agy cannot be invoked, return nothing.
