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

With no annotations, the description carries the burden, and it does disclose the key operational requirement: an Authorization bearer key with operations:read scope. It does not say whether the call is read-only/paginated, whether it returns all assigned operations or only outstanding ones, or what shape the response takes.

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 sentences, front-loaded with the action and followed by the auth prerequisite. Nothing is redundant or padded.

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 zero-parameter list tool with no output schema, the description covers what it returns at a high level and the auth needed. Missing only return-shape or pagination details, which are minor at this complexity.

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?

The tool takes zero parameters, so the baseline is 4. The description correctly implies the agent identity is supplied by the bearer credential rather than a parameter, which is useful framing for an empty schema.

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 states a specific verb and resource (list operations) and scopes it to 'the calling coordinator agent', which separates it from siblings like read_assigned_operation_evidence and reconcile_assigned_operation. It could go one step further and explicitly name which sibling handles evidence retrieval or reconciliation, but the identity of the tool is unambiguous.

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?

Usage is implied: an agent calls this to enumerate the operations assigned to it. There is no explicit when-to-use/when-not-to-use guidance, nor a pointer to the natural follow-ups (read_assigned_operation_evidence, reconcile_assigned_operation), 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.
