create_migration_test_plan

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

No annotations are provided, so the description must carry the burden. It explains the tool generates a plan with test cases and does not execute anything (present for approval). However, it does not mention whether the plan is stored or how it is returned, leaving some behavioral ambiguity.

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 well-structured with a clear opening sentence followed by detailed bullet points of all 8 phases. It is somewhat verbose but each point serves to clarify the output. The main purpose is front-loaded, though the phase details could be more concise without losing clarity.

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 (7 parameters, nested objects, no output schema), the description lacks explanation of how input parameters influence the generated plan. It thoroughly describes the output but omits the relationship between inputs and outputs, leaving the agent uncertain about parameter usage.

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 description coverage is 57%. The description does not elaborate on parameter meanings or usage beyond what the schema provides. Key parameters like 'analysis', 'field_mappings', and 'transform_rules' are not explained in context, so the description adds minimal value to 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 verb 'generate' and the resource 'full expert migration test plan', with a specific audience and goal ('for user approval before executing'). It details the 8 testing phases, making it distinct from sibling tools like 'create_test_plan'.

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 clear usage guidance: 'Present the plan to the user for approval, then call run_approved_tests'. This gives a workflow context. It does not explicitly exclude alternatives but the specificity of 'migration test plan' differentiates it from generic test plan tools.

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