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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds only the endpoint mapping ('GET /tasks/{id}'); it says nothing about not-found behavior, error responses, or whether the returned task includes related entities — the kind of context that would add value beyond the structured fields.

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 very short fragments with zero filler, and the core meaning is front-loaded. It is arguably under-specified rather than bloated, but nothing in the text is wasted.

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 getter this is close to adequate, and annotations plus full schema coverage carry most of the burden. The notable gap is the absence of an output schema: the description never hints at what a task object contains, leaving the agent to discover the return shape by calling it.

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 coverage is 100% and the single task_id parameter is fully documented in the schema, so the description is not required to compensate. It adds no new semantics about the id (e.g. where to obtain one), which is consistent with the baseline 3 for high-coverage schemas.

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 a specific verb and resource ('One task by id') and adds the REST endpoint, so the retrieval intent is unambiguous. However it does not differentiate itself from siblings like list_tasks or search_all, so the agent must infer that this is the single-record lookup path.

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 explicit when-to-use statement and no named alternative. The agent can infer 'use when you already have a task id' and that list_tasks is the counterpart, but nothing in the text confirms this or states a prerequisite such as needing a valid id.

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