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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds two useful behavioral facts beyond that: sub-sections are included in the result, and no partner key is required. It is silent on ambiguous or unmatched headings (error vs. best match), which is the main remaining behavioral unknown.

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?

A single well-formed sentence with the core action front-loaded, followed by examples and an auth note that earn their place. The example list is slightly long but directly supports the required heading parameter.

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 two-parameter read-only docs lookup with full schema coverage and no output schema, the description is nearly complete. The only meaningful omission is what happens when the heading does not match or matches multiple sections.

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 coverage is 100%, so both parameters are already documented, including the doc enum. The description adds value by grounding the 'heading' parameter with four concrete real-world examples, but adds nothing about matching behavior beyond what the schema states.

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 states a specific verb and resource ('Return the full text of one section ... of the WasapFlow Bridge docs') and clarifies the scope includes sub-sections. It does not explicitly differentiate itself from the sibling bridge_docs_search, so it falls short of a 5.

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?

Usage is only implied: the phrase 'full text of one section' hints this is the read-by-heading counterpart to bridge_docs_search, but no sibling is named and there is no explicit when-not guidance. The four example headings help an agent recognize the intended input shape, which is the main practical guidance provided.

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