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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, lowering the burden. The description adds the useful detail that the token originates from an invite email, but says nothing about what happens on success (joining the org), permission errors, or token expiry.

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?

One short sentence with the action and the parameter's source front-loaded; nothing redundant or padded.

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 a single-token operation with a clear safety profile in annotations and no output schema, the description covers what an agent needs to invoke it. Only minor gaps remain, such as the result of a successful acceptance.

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 0% and the single parameter is only typed as a string, so the description must compensate. It does so by clarifying that the token is the one from the invite email, which is meaningfully more than the schema provides, though format/expiry details are absent.

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?

States a specific verb (accepts) and resource (organization invitation), which is unambiguous among siblings like org_invite_create, org_invite_list, and org_invite_revoke. It doesn't explicitly name or contrast with those siblings, keeping it just short of a 5.

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 phrase 'with the token from the invite email' implies the usage context (redeeming an emailed invitation) but gives no explicit when/when-not guidance or alternatives such as org_invite_create for issuing invites or org_login_verify for other token flows.

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