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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is covered. The description adds genuinely extra context: the download link is authenticated and optional, and no raw binaries or credentials are ever returned through MCP — a useful security boundary. It does not cover error behavior or what 'owned' enforcement means.

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 dense sentences with the payload description front-loaded and no filler. The null-return caveat is correctly placed last, though the vocabulary is compressed enough to be opaque to a first-time caller.

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 no output schema, the description carries the return-value burden and does so by listing the response components and the negative guarantee about binaries/credentials. Missing only the prerequisite chain (how to get task_id) and failure modes, which keeps it short of a 5.

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?

Only task_id exists and the schema fully constrains it (UUID format plus a strict pattern), so structural semantics are already handled. The description adds that the task must be 'owned' and refers to an 'exact revision', which hints at access control and revision semantics, but does not say how to obtain the id or how to pin a revision.

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 read operation ('Read the exact owned task revision') and enumerates what comes back: revision, digest, missing owner/provider actions, and a ZIP download link. It is clearly the single-task counterpart to list_publisher_tasks/create_publisher_task, though the jargon ('owned task revision', 'digest') is not defined.

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 statement of when to use this versus list_publisher_tasks or authorize_publisher_task, and no guidance on where the task_id comes from. The agent must infer that this is the follow-up read after a task is created or listed.

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