get_renderer_file

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

No annotations are provided, so the description carries the burden of behavioral disclosure. 'Get the contents' clearly signals a read-only, non-destructive operation. However, it does not describe what happens for missing files, directory paths, or very large files, nor does it specify the return format. It is transparent enough for a simple fetch but lacks depth.

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?

Two sentences with no padding. The main action is stated first, followed by a brief utility note. Every sentence earns its place, and it is easy to scan quickly.

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 simple one-parameter tool with no output schema, the description covers the core purpose and typical use cases. It could be more complete by mentioning that file paths may be discovered via list_renderer_files, but the essential information for a basic call is present. It is adequate without being exhaustive.

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 input schema already fully documents the only parameter, 'path', with examples. The description adds little beyond the schema—it repeats that the file is from the repository. This meets the baseline of 3 given 100% schema description coverage, but the description does not enhance understanding of the path parameter.

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 uses a specific verb and resource: 'Get the contents of a specific file from the Renderer repository.' This clearly distinguishes it from sibling tools like list_renderer_files (which lists files) and get_config_example (which gets a specific config example). The purpose is unambiguous.

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 phrase 'Useful for viewing examples, configs, or source code' provides general context for when to use the tool, but it does not explicitly mention alternatives or exclusion criteria. An agent would benefit from a pointer to list_renderer_files for discovering file paths, but the guidance is not misleading—just minimally sufficient.

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