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

With no annotations, the description should disclose side effects, authentication needs, and error conditions. It only mentions 'Requires API key' but does not describe what actions are destructive (e.g., cancel_task) or idempotent, nor does it explain the lifecycle of tasks or potential failures. The description is too generic for a tool with 9 actions.

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 brief (two sentences) but it crams six actions into one list without grouping or hierarchical structure. It is not structured to help an AI quickly understand the workflow or action categories. Could be more efficient by organizing actions into groups.

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?

Given the tool's complexity (11 parameters, 9 actions) and no output schema, the description is insufficient. It does not explain return values, the workflow for task lifecycle (e.g., create -> browse -> accept -> submit -> verify), or how parameters vary by action. The agent would need significant additional context to use this tool correctly.

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%, so baseline is 3. The description adds no extra meaning beyond listing action types; it does not explain parameter relationships (e.g., which parameters are required for each action) or provide usage examples. It meets the minimum but does not leverage the opportunity to clarify parameter semantics.

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 clearly states the tool is a 'Task marketplace' and lists six specific actions (browse, create, accept, submit, verify completions, send messages), giving a good sense of purpose. However, it does not differentiate from sibling tools like 'agent_tasks' or 'skill_market' which may have overlapping functionality.

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 on when to use this tool versus alternatives. The description provides no context about when to choose 'task_market' over siblings like 'agent_tasks' or 'skill_market', nor does it mention prerequisites or state dependencies (e.g., tasks must exist before messaging).

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