read_file

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly states 'Read', which clearly indicates a non-mutating operation, and mentions 'active workspace' as a precondition. However, it does not disclose additional behavioral details such as error handling for missing files, permission requirements, or potential size limitations. The transparency is adequate but not rich.

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 a single, concise sentence that front-loads the action and resource. There is no wasted text, and it quickly communicates the core functionality. It would be a 5 if it also provided a brief note on parameters or usage, but as is, it is appropriately concise.

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?

Given that the tool is simple (two parameters) but has zero schema description coverage and no output schema, the description should provide enough detail for an agent to call it correctly. It does not explain the meaning of path or workspace_id, nor does it clarify what 'active workspace' entails. An agent would have to infer critical parameter semantics, making the description incomplete for reliable invocation.

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 0%, so the description must compensate for the lack of parameter documentation. It mentions 'a file's content' and 'active workspace', which gives some context for the path and workspace_id parameters, but it does not explain the expected path format (absolute vs relative), how workspace_id should be specified, or any constraints on these values. The description adds minimal semantic value beyond the parameter names themselves.

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 states the action 'Read' and the resource 'a file's content', and adds the scope 'from within an active workspace'. This distinguishes it from sibling tools like list_files (which lists files) and search_files (which searches), making the purpose 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 description provides context that the tool operates 'within an active workspace', which implies it should be used when reading file content. However, it does not explicitly state when to use this tool versus alternatives such as list_files or search_files, nor does it mention any exclusion conditions. Guidance is implied but not made explicit.

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