set_library_path

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

No annotations are provided, so the description must disclose behavior itself. 'Set' implies a mutation, but there is no information on persistence, side effects, required permissions, or whether it validates the path. The description adds almost nothing beyond the action itself.

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, short sentence with no wasted words. It is appropriately concise for a simple setter, though it could include a bit more context without bloat. Structure is fine and front-loaded with the action.

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 the tool's role as a configuration setter among read/convert tools, the description should explain when to use it (e.g., before querying volumes) and any effects. An output schema exists but the description still lacks necessary context about persistence or prerequisites. Completeness is low for the tool's purpose.

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 coverage is 100% (the single parameter has a full description). The description adds no additional meaning beyond the schema; it merely restates the action. Baseline 3 is appropriate because the schema already documents the parameter fully.

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 clear verb 'Set' with a specific resource 'path to the Digitale Bibliothek collection'. It is unambiguous and distinct from sibling tools, which are all about reading, searching, or converting volumes. No other tool sets a path, so it is easily differentiated.

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 guidance is given on when to use this tool versus alternatives, nor any prerequisites or ordering. For instance, it does not mention that the path should be set before using other tools, or that it is a configuration step. The description is purely declarative without context.

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