get_annotations

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

With no annotations, the description carries the burden of behavioral disclosure. It indicates a read-only retrieval operation and specifies that it returns all human and AI annotations, but it does not mention pagination, ordering, authentication, or return format, so behavioral detail is only partially covered.

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, front-loaded sentence with no filler. Every word contributes to the functional meaning: the verb, the annotation categories, and the session scope.

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 simple one-parameter getter with no output schema, the description covers the essential what and scope. It lacks an explicit pointer to sibling tools or return shape, but the operation is straightforward and the core invocation detail is present.

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 schema already documents sessionId with 100% coverage, so the baseline is 3. The description's 'for a session' expression simply restates the parameter's role and adds no format, syntax, or edge-case meaning beyond the 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 uses the specific verb 'Retrieve' with the resource 'annotations' and clarifies scope ('all human and AI' and 'for a session'). It clearly differentiates the tool from session and event tools by its annotation-focused resource, though it does not explicitly name any sibling.

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?

There is no guidance on when to use get_annotations versus siblings such as annotate_session or get_events. It does not mention prerequisites, alternatives, or the specific context in which this tool is preferred, leaving selection to inference.

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