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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so the safety profile is covered. The description adds a small behavioral detail by mentioning 'privacy-filtered project metadata,' but it does not clarify what is filtered or what the response contains.

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?

The description is a single sentence and front-loads the verb 'Read,' which is good. However, 'hosted get' is grammatically awkward and 'using privacy-filtered project metadata' is vague enough that the sentence does not read as cleanly as it could.

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 status tool with one parameter, the description plus annotations are partially adequate, but there is no output schema and the description gives no indication of the response shape, status values, or polling behavior. The agent is left to infer important details beyond the parameter name.

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 0%, and the description does not mention executionId or explain how it maps to the agent execution. The parameter name and schema pattern provide clues, but the description itself adds no parameter meaning and does not compensate for the missing schema descriptions.

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?

The description uses the verb 'Read' to identify this as a retrieval operation and 'agent execution status' names the resource, distinguishing it from lifecycle siblings like begin_agent_execution and finalize_agent_execution. It loses a point because it does not explicitly name alternatives and the phrase 'hosted get' is awkward.

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 implies this is the tool to use when an agent needs execution status, and 'privacy-filtered project metadata' hints at the data source. However, it does not explicitly state when to prefer this tool over related tools or describe exclusions, so usage context is only implied.

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