Invite People To SharePoint Item

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

Annotations are absent, so the description must carry the burden. It clearly states the access-granting action and target, but does not disclose side effects such as invitation emails, sign-in requirements, or whether existing permissions are overwritten. This leaves some behavioral ambiguity for a mutation tool.

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?

The description is extremely concise: one English sentence plus Chinese equivalents. It front-loads the key action and resource without any fluff, making it easy to scan.

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?

For an action tool with a rich schema and no output schema, the description provides the essential context. However, it lacks a mention of how permissions are applied (e.g., role mapping) and does not reference the optional parameters that affect behavior, leaving some completeness gaps.

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 description coverage is 100%, so a baseline of 3 is appropriate. The description adds minimal semantic value beyond the schema by referencing 'selected people' (recipients) and 'read or write' (roles), but does not elaborate on parameter formats or behaviors.

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?

The description uses a specific verb ('Grant') and clearly identifies the resource ('SharePoint file or folder') and the access levels ('read or write'). This distinguishes it from generic drive tools by explicitly mentioning SharePoint, and the Chinese intents reinforce the intended use case.

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?

The description does not explicitly explain when to use this tool versus alternatives like drive_invite_item or share links. It only provides context that it works with SharePoint items, which is implied by the name. No exclusions or alternative tool references are provided.

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