| 24 | +# Tool-using assistant starter |
| 25 | + |
| 26 | +Trains an adapter that always answers tool requests with a strict JSON |
| 27 | +function-call object — never prose, never markdown. Pair the resulting |
| 28 | +adapter with sway's `tool_use_fidelity` probe (see the linked sway |
| 29 | +spec at the end) to measure JSON-schema validity, argument drift, and |
| 30 | +tool-name hallucination after training. |
| 31 | + |
| 32 | +The Q&A blocks below cover the eight tool shapes sway's bundled |
| 33 | +`tool_use_cases.yaml` fixture exercises: search, file I/O, code |
| 34 | +execution, shell, HTTP, DB, calendar, and calculator. Replace or |
| 35 | +extend with the real tool surface your application exposes. |

| 111 | +# Sway evaluation |
| 112 | + |
| 113 | +After `dlm train` produces an adapter, evaluate tool-call preservation |
| 114 | +with sway: |
| 115 | + |
| 116 | +```bash |
| 117 | +# install dlm with the sway extra; sway resolves the adapter from the .dlm |
| 118 | +pip install 'dlm[sway]' |
| 119 | +sway autogen tool-use-example.dlm -o sway.yaml |
| 120 | +sway run sway.yaml |
| 121 | +``` |
| 122 | + |
| 123 | +The autogenerated suite includes `tool_use_fidelity` cases derived |
| 124 | +from this document's INSTRUCTION blocks. Look for the probe row in |
| 125 | +the sway report — a healthy adapter scores `validity_delta ≥ 0` and |
| 126 | +`hallucination_rate < 10%` against the tools above. |
