create_defect

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

No annotations are provided, so the description must disclose behaviors. It only restates parameter requirements (name, projectId) without mentioning what happens on success (e.g., returns defect ID), error conditions, or authentication needs. This is insufficient for a creation tool.

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 one sentence plus a list of required/optional fields. It is extremely concise with no redundant information, earning its place efficiently.

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 is simple but lacks mention of return value (e.g., defect ID) or error handling. No output schema exists, and the description provides no behavioral context beyond parameters. This is incomplete for guiding agent invocation.

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 schema has 100% coverage but lacks type information for inner properties (additionalProperties: true). The description adds types: 'name (string), projectId (number)' and optional description, which clarifies meaning beyond the schema. It adds value but could be more detailed.

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's purpose: 'Create a new defect record to group a novel failure pattern.' It uses a specific verb ('Create') and resource ('defect record'), and distinguishes from sibling tools like update_defect by emphasizing 'novel failure pattern'.

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 implies usage for new failure patterns but does not explicitly state when not to use it or mention alternatives like update_defect for existing defects. It provides minimal guidance on context.

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