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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds one useful behavioral note — that results are "privacy-filtered project metadata" — but does not explain what a route agent task actually is or what filtering removes.

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?

A single front-loaded sentence with no filler or redundancy. It is appropriately compact, though the terseness leaves the tool's purpose under-explained for a four-parameter operation.

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?

With four parameters, an unusual domain concept ("route agent task"), and no output schema, the description is too thin to be complete. It never states what the task object contains, what the privacy filtering hides, or when this tool is the right call among the many sibling read tools.

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%, so the schema already documents all four parameters and the baseline is 3. The description adds nothing beyond the schema, and notably the schema itself reuses a copy-pasted "Owned project ID" description for sessionId and executionId, which the description does not clarify.

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 names a verb ("Read") and a resource ("hosted route agent task"), giving a basic sense of purpose. However, "route agent task" is an opaque concept and the phrasing is close to restating the tool name. It does nothing to distinguish this from siblings like get_agent_execution_status, agent_action, or start_agent_session.

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?

There is no guidance on when to use this tool versus the many adjacent read/status tools in the family (get_agent_execution_status, get_project_status, agent_action). No prerequisites, no exclusions, no alternatives are named. The agent must infer usage entirely.

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