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. While it mentions the requirement for a continuation ID, it doesn't describe what happens during continuation (does it append to previous thinking? replace it? create a new session?), what the output looks like, whether there are rate limits, or any error conditions. For a tool with no annotation coverage, this leaves significant behavioral gaps.

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 perfectly concise with two sentences that each earn their place. The first states the purpose, the second specifies the prerequisite. There's zero waste or redundancy, and the information is front-loaded appropriately.

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 moderate complexity (continuing a thinking session), no annotations, no output schema, and 100% schema coverage, the description is adequate but has clear gaps. It explains what the tool does and the prerequisite, but doesn't describe the continuation behavior, output format, or error handling. For a tool that presumably maintains state across operations, more behavioral context would be helpful.

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 the schema already documents both parameters thoroughly. The description mentions the continuation ID requirement and that additional_input is for 'additional context or questions to incorporate,' which adds some semantic context about how the parameter is used, but doesn't provide significant value beyond what's already in the schema descriptions.

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's purpose: 'Continue a previous thinking session with additional context or refinement.' It specifies the verb ('continue') and resource ('previous thinking session'), but doesn't explicitly differentiate from the 'think' sibling tool beyond mentioning it requires a continuation ID from a previous think operation.

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 provides clear context for when to use this tool: when you have a continuation ID from a previous think operation and want to add more context or refinement. It doesn't explicitly state when NOT to use it or name alternatives, but the requirement for a previous think operation implies this is for continuing rather than starting new sessions.

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