open_desk

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

No annotations are provided, so the description carries the full burden for a mutating tool. It discloses that it writes a fixed file and opens it, but does not state whether it overwrites an existing file, what content is written, what permissions are needed, or what happens on failure.

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 two short sentences with no filler, and the main action is front-loaded. It could be slightly clearer about whether 'open' is a side effect after writing, but it is efficiently structured.

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 tool with no annotations, no output schema, and a mutating file-write behavior, the description omits important context: overwrite behavior, content source, error conditions, and prerequisites. The zero-parameter schema simplifies the call, but the behavioral gaps remain significant.

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 has zero parameters, so there are no parameter semantics for the description to clarify. The baseline score of 4 is appropriate.

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 names specific actions and a concrete resource: writing KnowledgeBase/desk/index.html, returning its path, and opening the file from disk. This is clearer than a vague 'open desk' description, though it does not distinguish the tool from siblings such as start_desk_server or get_desk_summary.

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?

It provides no guidance on when to use this tool versus alternatives like start_desk_server, get_desk_summary, or search_desk. The agent must infer the context entirely.

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