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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only states that agents are matched to a task; it does not mention whether this is read-only, how matching works, how results are ordered, what the returned shape is, or whether limit affects behavior.

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 a single short sentence with no wasted words and the core concept is front-loaded. However, it is more under-specified than genuinely concise, missing a verb and key context.

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 annotations, no output schema, and 0% parameter documentation, the description is too thin for an agent to fully understand the call contract. The agent must infer return format, parameter semantics, and operational behavior from the tool name and schema alone.

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 adds little parameter meaning beyond the schema. 'This task' loosely associates taskId with the task, but limit is completely unexplained, and no details are given for how either parameter affects the returned matches.

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, 'Agents from the index that could do this task,' clearly identifies the resource (agents) and the task relationship despite lacking an explicit verb. It is understandable in context with the taskId parameter but does not explicitly differentiate itself from sibling tools like search_agents or list_tasks.

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?

No guidance is given about when to use task_matches versus alternatives such as search_agents, list_tasks, or task_solutions. The description implies a matching use case but provides no explicit context, prerequisites, or exclusions.

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