validate_reader_annotations

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. The verb 'validate' implies a read-only check, but it does not state whether the tool mutates anything, what happens on validation failure (e.g., errors vs. success), or any side effects. The description adds no behavioral detail beyond the core action.

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 sentence that starts with the action verb 'Validate'. It is concise, contains no redundant words, and immediately conveys the tool's purpose. Every word earns its place.

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 (3 parameters, output schema exists), the description adequately sets the context. The output schema is not required to be described per the rubric. However, it could mention that validation is typically performed after generating the HTML with 'convert_pdf_to_card_html', which would tie it better to sibling tools. Slight gap in completeness.

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 all three parameters. The description adds context by mapping 'notes/highlights sidecar' to annotations_path and 'generated reader HTML file' to reader_html_path, which reinforces the schema descriptions but does not provide new semantic details. Baseline 3 is appropriate.

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 verb 'Validate' and identifies the two resources: a 'notes/highlights sidecar' (annotation file) and a 'generated reader HTML file'. This distinguishes it from sibling tools like convert_pdf_to_card_html (which generates HTML from PDF) and publish_reader_bundle (which publishes a bundle). The purpose is specific and 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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention typical use cases, prerequisites (e.g., that the HTML must be generated first), or when not to use it. The agent must infer the context from the tool name and siblings.

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