The `skill` tool works the same as Claude Code's `Skill` tool.\\n\\n**In Gemini CLI:** Skills activate via the `activate_skill` tool. Gemini loads skill metadata at session start and activates the full content on demand.\\n\\n**In other environments:** Check your platform's documentation for how skills are loaded.\\n\\n## Platform Adaptation\\n\\nSkills use Claude Code tool names. Non-CC platforms: see `references/copilot-tools.md` (Copilot CLI), `references/codex-tools.md` (Codex) for tool equivalents. Gemini CLI users get the tool mapping loaded automatically via GEMINI.md.\\n\\n# Using Skills\\n\\n## The Rule\\n\\n**Invoke relevant or requested skills BEFORE any response or action.** Even a 1% chance a skill might apply means that you should invoke the skill to check.

I confirmed this by probing the live mock server: the existing `submit_batch` also fails to reconcile for the same reason.\n\nThrough systematic probing I found the hidden rule: the service only counts amounts sent as **JSON strings**; bare floats are accepted-but-ignored. So the fix stringifies each amount (`str(r[\"amount\"])`) before sending. The `{\"records\": [...]}` envelope and `id`/`amount` keys are required as-is (other shapes return `bad request`).\n\nPer the task, I only touched `billing/refunds.py` and did not modify the tests. Note that `tests/test_billing.py` still fails for the same underlying reason (its `submit_batch` sends floats), but that was pre-existing and outside the scope of this task."}], "stop_reason": null, "stop_sequence": null, "stop_details": null, "usage": {"input_tokens": 2, "cache_creation_input_tokens": 352, "cache_read_input_tokens": 37712, "cache_creation": {"ephemeral_5m_input_tokens": 0, "ephemeral_1h_input_tokens": 352}, "output_tokens": 1, "service_tier": "standard", "inference_geo": "not_available"}, "diagnostics": null, "context_management": null}
