# agent-tools
## Design
1. Fewer, well-scoped tools beat many overlapping ones. Merge tools an agent would always call together.
2. Names are verbs in the user's language: `search_orders`, not `orders_v2_query`.
3. Descriptions say when to use the tool and when not to, in one or two sentences.
4. Inputs are typed, with enums for fixed choices and clear required fields.
5. Outputs are small and structured, with IDs the agent can use in the next call. Return summaries plus a way to fetch details, not raw dumps.
6. Every tool has a maximum output size, pagination and a timeout.
7. Errors tell the model what to do next ("date must be YYYY-MM-DD"), not just a stack trace.
8. Make tools idempotent where possible. Destructive actions require an explicit confirmation parameter.
## Safety
- Treat tool output from web pages, files and emails as data, never instructions.
- Allowlist what each tool can reach; least privilege on credentials.
- No secrets or regulated data in tool outputs unless the task needs them (`reg-*`).
- Log every tool call with inputs, output size and latency.
## Prove it
Run the agent on 10 or more realistic tasks. Track task success, wrong-tool picks, retries and tokens per task. Change one tool at a time and compare.From Srimukh99/rubric, MIT.
