generate_migration

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

No annotations are provided, so the description must disclose behavioral traits. It only states that it generates a migration class, but does not mention whether it writes to disk, overwrites existing files, requires permissions, or any side effects. This is insufficient for an agent to understand the full impact of invocation.

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 at two sentences, front-loaded with the primary purpose. Every sentence adds value without redundancy. It is well-structured for quick parsing by an AI agent.

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?

The tool generates a migration file, yet the description lacks details about file naming conventions, directory placement, and whether the migration affects the database schema immediately. The 4 parameters and no output schema mean the description should provide more context to compensate, but it does not. Incomplete for a code generation 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?

Input schema has 100% description coverage for all 4 parameters, so the schema already provides meaning. The description adds no additional context beyond restating that fields are specified with types. Given the high schema coverage, a score of 3 is appropriate as the description does not further enhance parameter understanding.

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 generates a database migration file with column definitions. It specifies the verb 'generate' and resource 'database migration file'. However, it does not explicitly differentiate from sibling tools like generate_model or generate_controller, which also generate code artifacts, but the specific resource type is distinctive enough.

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 provides no guidance on when to use this tool instead of alternatives. It does not mention prerequisites, when to choose different migration actions (create, add, modify, drop), or when not to use it. This omission limits the agent's ability to decide correctly.

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