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

With no annotations, the description carries the burden of behavioral disclosure. It does disclose the returned content and notes deliveries 'so far', giving some temporal context. However, it does not explicitly state read-only behavior, whether task_id must reference an existing task, or error/not-found behavior, leaving gaps.

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 one compact sentence that front-loads the key concept ('Full task detail') and separates the included fields after a colon. Every word adds value with no wasted text.

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 single-parameter retrieval tool, the description covers the important output fields and is largely sufficient. It could be more complete by noting how deliveries are represented and by signaling when task_deliveries or list_tasks should be used instead, but these are minor for correct invocation.

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% for the only parameter, task_id, so the baseline is 3. The description does not add new parameter semantics beyond the schema, but none are needed for a single well-documented identifier parameter.

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 states the tool returns 'full task detail' and enumerates the included fields (description, tags, budget, status, deliveries), so an agent can tell it from a list operation. It does not explicitly name or contrast sibling tools such as list_tasks or task_deliveries, so it misses the top of the scale.

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 phrase 'full task detail' implies this is the tool to use when all details for one task are needed, but there is no explicit guidance on when to prefer it over list_tasks or task_deliveries, nor any when-not-to-use conditions. The intended usage must be inferred rather than stated.

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