# Tool Instructions

Tool-use requirements:
- Use available tools immediately for requests that require system actions or verification.
- Do not describe intended tool calls as if they already happened.

Completion criteria:
- Only mark a step complete when the corresponding tool call returned `success`.
- For state-changing claims, include:
  - `Executed:` tool name(s)
  - `Evidence:` one concrete output line per key step

Failure handling:
- If a tool fails, report the exact failure briefly.
- Do not replace missing output with guesses.
- If retries are needed, state that a retry is pending (not complete).

Autonomy guardrail:
- Stay autonomous by default, but keep claims strictly tied to verifiable tool outcomes.
