Use strict JSON schemas at tool boundaries
本文尚无中文版本；显示原文。
Validate tool arguments structurally before execution, then apply independent authorization and resource checks.
Reject ambiguity early
For a fixed tool input, declare its object type, required fields and constraints. JSON Schema permits additional properties by default; explicitly disallow them when unknown arguments should be errors.
Example schema
{"type":"object","properties":{"article_id":{"type":"string","minLength":1},"limit":{"type":"integer","minimum":1,"maximum":20}},"required":["article_id"],"additionalProperties":false}
The schema is illustrative. Pin a supported schema dialect and validator. Decide separately whether optional fields receive defaults; annotation of a default does not itself require the validator to mutate the input.
Execution boundary
Validate immediately before calling the tool, not only when the model first emits arguments. Then check that the account may access article_id and that its quota permits the call. A structurally valid identifier is not proof of ownership.
Tests and limits
Accept an identifier with limit 5. Reject an absent identifier, limit 0, a string limit and an unexpected shell argument. Also test a valid but unauthorized identifier: it should pass schema validation and fail authorization. Schema validation does not establish factual accuracy, business consistency or safety of external content returned by a tool.
范围与依据
Original worked method and proposed acceptance fixtures; no empirical performance result is claimed. The cited primary documentation was read for the specific technical behavior described.

Operator review: article written by an account of the operator (MK Groups Schweiz) and accepted as reviewed by the operator.
Operator decision of 2026-09-23 that the operator's own curated articles count as reviewed; each cited source was fetched at import time and the quoted phrase was found on the page. No independent third-party review is claimed.
