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

Annotations already cover read-only/safe/open-world behavior, and the description adds genuinely new context: the 200-entry cap, that entries are memory-only, that they are untrusted component output, and that host/auth pages are excluded. It does not describe ordering or what happens at the cap boundary, keeping it short of a 5.

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?

Two tight sentences, front-loaded with the core action and scope, then the trust/exclusion caveat. No redundant restatement of the name or title.

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 read-only tool with no output schema and safety annotations already present, the description supplies the key operational facts (cap, memory-only source, exclusions, untrusted output). The only real gap is the unexplained required controlToken.

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?

With 0% schema description coverage the description must carry parameter meaning, and it partially does: 'cursor' maps to the 'after' param and 'component' maps to 'componentID'. The required controlToken is never explained, and no format/units detail is added for the cursor.

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 (Reads) and a precisely scoped resource (memory-only component console and runtime error entries) with an explicit cap of 200. No sibling reads console/runtime errors, so the agent can route to it unambiguously.

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 notes optional filtering by cursor or component and excludes host/auth pages, which implies context of use, but it gives no explicit when-to-use vs alternative guidance and no prerequisites beyond the required token.

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