plan_testing

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that the tool creates a strategy, but does not clarify whether this is a read-only planning operation, whether it generates a document or artifact, whether it modifies any existing resources, or what the output format is.

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 sentence that front-loads the core action and then efficiently lists the key deliverables. Every element adds value, and there is no redundant phrasing.

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 description covers the main deliverable areas and the schema fully documents inputs, so the tool is callable. However, there is no output schema and no mention of what the returned strategy looks like, how it is structured, or where it fits among sibling planning tools.

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 provides 100% description coverage for all three parameters, including enum values and the meaning of 'features'. The description does not need to repeat parameter details, so the baseline of 3 is appropriate.

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 uses a specific verb ('Create') and resource ('comprehensive testing strategy') and enumerates concrete deliverables: test pyramid, tool recommendations, coverage targets, performance testing plan, CI integration, and setup checklist. This clearly distinguishes it from siblings like create_performance_budget, which targets a narrower artifact.

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 gives no guidance on when to use this tool versus alternatives such as create_performance_budget, plan_devops, or analyze_project. It does not mention prerequisites, typical scenarios, or cases where a sibling would be more appropriate.

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