MySQL Write Query

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

Annotations indicate readOnlyHint=false and destructiveHint=false, but the description confirms writes. Adds safety context about prepared statements, but does not disclose auto-commit behavior, error handling, or return value structure (though output schema exists). No contradiction with annotations? Actually description says writes, annotations say destructiveHint=false, which is a mismatch.

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?

Two sentences, front-loaded with operation type. No unnecessary details; every word earns its place.

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?

With output schema present, return values need not be explained. However, the description lacks guidance on transaction integration and behavior on failure. Still, for a write tool with 6 params, it is reasonably complete.

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% with descriptions for all 6 parameters. The description adds minimal value beyond schema ('prepared statements for safety' relates to params). No additional semantics for individual parameters.

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?

States clearly the verb 'execute', resource 'write SQL query', and lists specific operations (INSERT, UPDATE, DELETE). Distinguishes from read-only siblings like 'mysql_read_query'.

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?

Implies usage for write operations, but no explicit guidance on when to use this vs transaction-based tools like 'mysql_transaction_execute' or when not to use it (e.g., for DDL). Lacks context about prerequisites or alternatives.

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