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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safe read-only behavior is established. The description adds useful behavioral and output context: default limit of 120, max of 500, and the exact output structure. It does not contradict annotations and covers what an agent needs for a list operation.

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 compact, well-structured with clear 'When to call', 'Input Requirements', and 'Output' sections. Every section earns its place, and the content is front-loaded with the core purpose before additional guidance.

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?

Despite having no output schema, the description documents the return object shape. With only two optional params, read-only annotations, explicit usage guidance, and a complete output contract, the description is fully sufficient for an agent to decide correctness and invoke the tool.

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%, and the description mostly restates what the schema already provides: optional product enum and limit with default/max. It adds context about scoping to one of the four products, but it does not significantly deepen the parameter 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 opens with a specific verb+resource: 'List indexed bundled docs pages across all four products with slugs, titles, and canonical URLs.' It clearly distinguishes the tool from siblings by contrasting it with dero_docs_search and dero_docs_get_page, and names concrete examples like 'what TELA tutorials exist?'

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 an explicit 'When to call' section with concrete use cases: surveying docs, getting a slug catalog before dero_docs_get_page, and preferring dero_docs_search for specific questions. This directly tells the agent when this tool is the right choice and when it is not.

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