apply_defect_matchers

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

No annotations are provided, so the description carries full burden. It states what the tool does but lacks details on side effects (e.g., whether test results are modified, if it creates links, idempotency, permissions required). Critical behavioral traits are missing.

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 three sentences with no redundant information. It is front-loaded with the main action and provides quick understanding. 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 no output schema and one parameter, the description is partially complete. It explains what the tool does and when to use it, but lacks behavioral details and prerequisites (e.g., that defect matcher rules must be configured beforehand). More context is needed for a complete understanding.

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% and the schema already describes the only parameter as 'Launch ID. Must be a number (integer), not a string.' The description adds no extra semantic value beyond what the schema provides, so baseline score 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 clearly states the action (apply), the resource (defect matcher rules to a launch), and the purpose (auto-triage unresolved test results). It distinguishes from sibling tools like create_defect or find_similar_failures by specifying this is an automated application of configured rules after launch completion.

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 explicitly says 'Run this after a launch completes to auto-group failures', providing clear when-to-use guidance. It does not explicitly state when not to use or list alternative tools, but the context is sufficient for correct usage.

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