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.

It returns {\"status\":\"accepted\"} but SILENTLY records 0 for any record whose `amount` is a JSON float. It only reads `amount` when sent as a JSON string (parsed to float) or a JSON integer (face value).\n\nProbed /refund with a single amount=10.0 record: JSON float 10.0 -> totals.refund=0; JSON string \"10.0\" -> totals.refund=10.0; JSON int 10 -> totals.refund=10.0. Since real amounts have cents (e.g. 12.50, 7.50), integers lose the decimal, so use STRING.\n\nFix in billing/refunds.py submit_refunds(): serialize as `\"amount\": str(r[\"amount\"])`, POST {\"records\":[...]} to /refund. This makes tests/test_refunds.py::test_refund_reconciliation pass (12.50+7.50 reconciles to 20.00). Same fix pattern as billing/client.py submit_batch().
