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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses that the tool blocks and returns instructions if tasks are pending, and returns a full grouped summary when resolved. However, it does not detail side effects like whether the investigation is permanently closed or tasks become locked, leaving some ambiguity about mutating 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 very concise at three sentences, front-loaded with 'FINAL CALL' to signal importance. Every sentence provides necessary context: purpose, blocking behavior, return value, and usage condition. No wasted words.

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 tool without an output schema, the description covers the essential aspects: what it does, when to call it, and what it returns (with grouping details). It omits specifics about the summary structure or irreversible consequences, but given the tool's simplicity and no schema, this is largely sufficient.

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 has zero parameters and the schema is an empty object, making schema coverage 100%. The baseline for 0 params is 4, and no additional parameter description is needed since there is nothing to describe.

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 identifies a specific verb and resource: 'Close out the investigation.' It distinguishes itself from sibling task-management tools by being the finalization step, with additional detail about blocking on pending tasks and returning a summary. This makes its unique purpose 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?

The description explicitly states when to use it: 'Call this when you believe all tasks are done.' It also implies the when-not by explaining that it blocks and returns actionable instructions if tasks are pending, effectively warning against premature invocation. This is clear usage guidance with implied exclusions.

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