winops_acl_grant

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations are all false, including destructiveHint: false contrary to expectations for a grant operation. The description does not disclose that granting might change existing permissions or is potentially destructive if permissions override. It provides no warnings or prerequisites. No contradiction with annotations, but it misses important behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is very concise: two sentences plus a code block for return format and example. No fluff, well-structured with headers.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Has output schema, so return format is covered. But lacks guidance on prerequisites (e.g., admin rights), effect on existing permissions, and whether the permission replaces or adds. For a mutation tool with destructiveHint false, more context is needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with each parameter described. The description adds a return format example and further illustrates usage with an example, but does not add much beyond the schema. Baseline 3, and the example adds minor value, so 4 is reasonable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clear verb (Grant) and resource (file/directory). Distinguishes from siblings like winops_acl_revoke (revoke) and winops_acl_get (get). However, it doesn't explicitly state the permission level semantics beyond the enum, but the enum covers that. Purpose is well-defined.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description includes a return format and examples, implying usage for granting permissions. It does not explicitly state when not to use it or mention alternatives, but the sibling tools like revoke and get provide context. Clear but no explicit when-not-to.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
