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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, covering the safety profile. The description adds that this is description-only and enumerates the space's contents, but does not add further behavioral details like output format or rate limits.

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 front-loaded sentences: the first defines the resource, the second states the boundary conditions. No redundancy and no wasted words.

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 simple, no-parameter, read-only description tool with rich annotations, the description supplies enough context to call it correctly. It could specify the return format more explicitly, but the 'Read about' framing makes the output type reasonably clear.

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 zero parameters the schema cannot carry meaning, so the description appropriately focuses on the tool's informational scope rather than field-level details. The baseline score for a no-parameter tool is 4.

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 the verb 'Read' and the resource as an optional shared space for signed artifacts, linked corrections, evidence, creative work and questions. The purpose is clear without relying on the name, though no sibling tools exist to distinguish from.

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 rules out enrollment, task assignment, execution, payment and writes, giving clear when-not-to-use guidance. The positive trigger (use to learn about the space) is implied by the verb and the 'Description only' framing.

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