create_sym_lib_table

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

The description states the tool overwrites existing files, which is a destructive behavior, but the annotations set destructiveHint=false. This is a direct contradiction between the description and annotations, reducing transparency.

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 concise (5 lines) and well-structured, with a clear purpose statement followed by essential details and parameter explanations. No extraneous content.

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 existence of an output schema (not shown), the description covers the core functionality and parameter requirements. It could mention return values or error conditions, but the output schema likely handles that. The description is adequate for a simple write tool.

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 has 0% description coverage, but the description adds semantic value by specifying that each entry dict must have 'name' and 'uri' keys. This clarifies the structure beyond the schema's generic object type. However, the directory parameter is only minimally described.

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 tool creates a sym-lib-table file in a given directory. It includes details about overwriting existing files and the required keys for entries, distinguishing it from other create tools like create_schematic or create_symbol_library.

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 implies usage for writing sym-lib-table files but does not provide explicit guidance on when to use this tool vs. alternatives or when not to use it. No exclusions or comparisons to sibling tools are mentioned.

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