Convert bug to regression tests

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

Annotations already indicate idempotent (idempotentHint=true) and non-destructive (destructiveHint=false). The description adds value by stating the tool returns 'root cause analysis, affected areas, and generated test cases with steps,' clarifying behavioral outcomes beyond what annotations provide.

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 two concise sentences, front-loaded with the core action and outputs, with no extraneous words. Every sentence adds value.

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 moderate complexity (2 parameters, 100% schema coverage, no output schema), the description sufficiently explains inputs and outputs. It could mention any prerequisites (e.g., existence of a test harness) but is broadly 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%, so baseline is 3. The description adds semantics: it explains that 'severity' influences 'test priority ranking,' which is not in the schema description. This extra context helps the agent use the parameter effectively.

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 states a specific verb ('analyze' and 'generate') and resource ('bug report' and 'regression tests'), making the tool's purpose clear. It does not explicitly differentiate from siblings like 'build_regression_pack' or 'generate_test_scripts', but the focus on bug-to-test conversion is distinct.

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 advises providing a 'detailed bug description for best results,' which gives a usage hint but does not specify when to use this tool versus alternatives (e.g., when to use 'generate_test_scripts' instead) or when not to use it.

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