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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the useful detail that all fields and dates are returned, but nothing about pagination, missing-task behavior, or errors, which a lookup tool could reasonably mention.

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 short, front-loaded sentences with no filler — purpose first, usage second. Efficient, though the second sentence is boilerplate that could carry slightly more routing value.

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?

An output schema exists, so return values need no elaboration, and the annotations cover the safety semantics. The only real gap is that the two required identifiers are never explained in prose, which is a minor omission for a straightforward lookup.

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 mentions no parameter at all; the two required UUIDs (projectId, taskId) are documented only by their type/format in the schema. With low coverage the description is expected to compensate by clarifying the project/task scoping relationship, and it does not.

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 ('Get one task') and describes the scope of the return ('all of its fields, including full details and dates'). It is clearly a single-item fetch, distinguishable from clean_notes_list_tasks, though it never names the sibling explicitly.

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?

'Use when the user asks about a specific task' gives implied usage context, which is better than nothing. However, it does not state when-not to use it or name the obvious alternative (clean_notes_list_tasks) for multi-task queries, leaving routing to inference.

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