get_tool_types

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

No annotations are provided, so the description carries the full burden; it does disclose the return payload (a full .d.ts), which is genuinely useful since there is no output schema. It does not state that the call is read-only/no-side-effect, nor whether the declaration file is large or complete enough to rely on.

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 sentence with no filler, and the key information (what is returned and its format) is front-loaded. Nothing redundant.

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-param tool with no annotations and no output schema, describing the return as a .d.ts is the essential piece and it is present. What is missing is the connective tissue: that this output is meant to inform subsequent execute_code calls, and any note on size, staleness, or scope of 'downstream tools'.

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 takes zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies; the schema is an empty object and no parameter prose is needed.

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?

States a specific verb and resource: returns the complete TypeScript declaration file (.d.ts) covering all downstream tools. That is concrete enough to distinguish it from the only sibling, execute_code, though it never names that sibling or frames itself as a discovery step.

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?

No explicit when-to-use statement or exclusion versus execute_code; the usage is only implied by the word 'downstream tools'. An agent can infer this is a discovery/introspection call, but nothing tells it whether to call this first, when to skip it, or how the output relates to execute_code.

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