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

Annotations already declare destructiveHint=true and idempotentHint=false, and the description adds real context beyond them: the summary is persisted verbatim, re-approval moves the timestamp each time, and other tools gate on this call. It never explains why destructiveHint is set (what prior approval state is replaced), leaving a small gap for a write operation.

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?

Front-loaded with the action, then each subsequent sentence earns its place: persistence semantics, downstream dependency, and re-approval behavior. No filler or repetition of the tool name.

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 2-parameter mutation with no output schema, the description covers purpose, persistence, gating behavior, and repeat-call semantics. It stops short of describing permissions/auth requirements or what the caller receives back beyond the implied timestamp, which are minor gaps here.

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 only 50%, and the undescribed 'summary' parameter is exactly the one the description compensates for by enumerating its intended content (business, audience, voice, language, proposed topics) and stating it is stored verbatim. The workspaceId semantics are left to the schema, but overall this does more than the baseline of 3.

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 precise verb+resource: it records a human approval of their profile. An agent can immediately distinguish this from get_profile (read) and update_profile (edit) because the description frames the call as a committed approval record rather than a mutation of profile fields.

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?

Gives clear context for when to call it: downstream tools (complete_onboarding, plan_topics, the quarter planner) refuse with profile-not-approved until it has been called once, and re-approval after a change is explicitly expected. It does not, however, contrast itself with the sibling update_profile, so no explicit alternative/exclusion is stated.

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