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

With no annotations, the description carries full burden but lacks behavioral details. 'Rebuild' implies a write/mutation operation, but it doesn't disclose permissions needed, whether it's destructive (e.g., if it locks tables), execution time, or side effects. It mentions 'faster queries' as a benefit but not how or when this applies.

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, efficient sentence that front-loads the action ('Rebuild') and purpose. Every word contributes meaning, with no wasted text, making it highly concise and well-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?

Given the tool's complexity (a maintenance operation with potential performance impact), no annotations, and an output schema (which handles return values), the description is minimally adequate. It states what the tool does but lacks details on behavior, prerequisites, or error conditions, leaving gaps for safe agent use.

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 0 parameters, and schema description coverage is 100%, so no parameter documentation is needed. The description adds value by explaining the purpose without redundancy, earning a baseline 4 for clarity in a parameterless context.

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 ('Rebuild') and target ('task summary materialized table'), with the benefit ('for faster open task queries') providing context. It distinguishes from siblings like 'get_entity' or 'run_read_query' by focusing on table maintenance rather than data retrieval or entity operations, though it doesn't explicitly name alternatives.

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 provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., when performance issues arise), exclusions, or related tools like 'apply_performance_tuning' or 'get_database_health' that might inform its use.

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