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

No annotations are provided, so the description must carry the behavioral burden. It conveys that this is a static enumeration of bundled adapters and lists the output fields, which implies a read-only operation. However, it does not explicitly state side-effect-free behavior, determinism, environment assumptions, or any error/edge cases.

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?

One compact sentence, front-loaded with the core function and free of filler. The version pinning and output fields are conveyed efficiently without redundancy.

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 zero-parameter list with an output schema present, the description covers the essentials: what is listed and what details are included. It is slightly incomplete because it does not signal when to prefer this over sibling tools or clarify whether 'bundled' means only a fixed built-in set.

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?

With zero parameters, the description has nothing to compensate for; the baseline of 4 applies. It introduces no parameter ambiguity and the absence of parameter documentation is not a gap here.

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 identifies the resource ('agent adapters bundled with bernstein v3.19.2') and the fields returned (adapter name, binary, module). It is unambiguous about what the tool lists, though it does not explicitly differentiate itself from sibling tools like list_presets.

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 this tool versus alternatives, nor any exclusions or prerequisites. The intended usage is only implied by the name and content description; nothing tells an agent when list_adapters is the right choice over other listing tools.

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