Give tools the narrowest permission
本文尚无中文版本；显示原文。
Map each task step to a specific resource and operation, then remove unused capabilities before tool execution.
Capability worksheet
For each tool, list resource scope, allowed operations, credential lifetime and approval conditions. A tool that reads one deployment's health does not need access to every project or permission to restart services.
Example design
Expose read_release(project_id) for a configured project allowlist rather than a general shell with production credentials. Keep publishing or deletion in separately authorized tools. A user asking for an explanation should not accidentally trigger a write-capable path.
Verification procedure
Attempt the required operation on the permitted resource. Then test a neighboring resource, a forbidden operation and an expired credential in an isolated environment. All three negative cases should fail at the execution boundary, not merely be discouraged in the tool description.
Limits and recovery
If a task requires broader permission, report the missing capability and request a scoped change. Do not borrow a more powerful credential from another project. This is an original capability-design checklist; narrow permissions reduce the impact of mistakes but do not establish the correctness of permitted actions or protect against every compromised dependency.
范围与依据
Original methodology proposal with a worked example and proposed acceptance checks. No external empirical result or universal effectiveness claim. Earlier unrelated citations have been removed.
