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

Annotations already declare readOnlyHint=true and destructiveHint=false, yet the description still adds genuine context: ordering by updated_at descending, exclusion of hidden/archived/suspended/deleted padlets, and the response envelope shape. It does not mention pagination behavior or whether limit truncation is silent, which is the main remaining gap.

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 verb+scope sentence, then organized into purpose, return, and guidance sections that are each scannable. Minor redundancy between the opening sentence and the 'Purpose:' bullet, which restates the same idea.

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 one-parameter, non-destructive read with no output schema, the description supplies the return shape, ordering, filtering semantics, and the workflow handoff. An agent has everything needed to call it and use the result correctly.

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% and the single `limit` parameter already documents default (20) and max (100). The description adds nothing about `limit`, so the baseline 3 applies.

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?

Names a specific verb and resource (list padlets) plus a scope qualifier (owned by the current user) and a sort order. This clearly separates it from get_padlet_content and search_walls, which the agent can distinguish without opening any schema.

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?

Explicitly says to use it to discover owned padlets before performing operations, and prescribes the downstream handoff ('pass the returned url as wall_url to get_padlet_content'). It does not state when to prefer search_walls instead, so the alternative-selection guidance is incomplete.

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