get_task

Read-onlyIdempotent

Retrieve a task by its positive integer ID. The operation uses secure parameterized queries and input validation.

Instructions

Behavior3/5

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

Annotations already indicate readOnlyHint, idempotentHint, destructiveHint. The description adds no new behavioral context beyond the identifier constraint. No mention of error handling, permissions, or response format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, succinct sentence that immediately states the tool's purpose. No extraneous words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple get-by-ID tool with a single parameter, annotations, and output schema, the description is adequate. It covers the essential use case, though it could optionally mention behavior on missing IDs.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description mentions 'positive integer ID', which aligns with the schema's exclusiveMinimum:0, but adds no additional detail like format or examples. With 0% schema description coverage, the description partially compensates but offers minimal enhancement.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly specifies the action (Get), the resource (one task), and the identifier (positive integer ID). This distinguishes it from sibling tools like list_tasks (listing) and create_task (creation).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a specific task ID is known, but does not explicitly mention when-not to use it or suggest alternatives such as list_tasks for multiple tasks.

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