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

With no annotations provided, the description carries full burden but offers minimal behavioral disclosure. It states what content is retrieved but doesn't describe format (e.g., plain text, structured data), pagination, performance characteristics, error conditions, or authentication needs. For a tool with zero annotation coverage, this leaves significant 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 a single, efficient sentence that front-loads the core action ('Get all text content from the page') and adds clarifying details. It avoids redundancy and wastes no words, though it could be slightly more structured for readability.

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 no annotations, no output schema, and moderate complexity (extracting text content from a page), the description is incomplete. It lacks details on return format, error handling, performance, or how it differs from similar siblings like get-full-snapshot. The agent would need to guess key behavioral aspects.

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 0 parameters with 100% schema description coverage, so the schema fully documents the absence of inputs. The description appropriately doesn't add parameter details, maintaining focus on the tool's purpose. Baseline 4 is correct for zero-parameter tools.

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 ('Get') and resource ('all text content from the page'), specifying the content types (headings, paragraphs, lists) and purpose (reading and content extraction). It distinguishes from siblings like get-full-dom (full DOM) and get-screenshot (visual), but doesn't explicitly contrast with get-full-snapshot or get-interactive-snapshot.

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 implies usage for 'reading and content extraction' contexts, suggesting when this tool might be appropriate. However, it doesn't provide explicit guidance on when to use this versus alternatives like get-full-dom or get-full-snapshot, nor does it mention prerequisites or exclusions.

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