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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly discloses the key non-mutating behavior ('without updating the ticket'), which is critical for an agent to understand that this tool has no side effects on the ticket. It does not mention other behaviors like output format or data dependencies, but the core safety-relevant trait is covered.

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, front-loaded sentence that immediately states the action and object. Every word earns its place, and there is no superfluous information. It is an excellent example of conciseness.

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?

For a simple generation tool with no output schema and no annotations, the description is mostly complete: it states the purpose, the object, and the crucial non-mutation behavior. The only minor gap is that it does not describe the nature of 'the changes' (e.g., derived from branchName) or the comment's format, but these are not essential for selection and invocation given the clear schema.

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 100%, so all four parameters are already well-documented in the schema. The description adds no additional parameter-specific meaning beyond the overall context of 'about the changes', which is not explicitly linked to branchName or projectName. The baseline of 3 is appropriate since the schema does the heavy lifting.

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 function with a specific verb ('Generate a comment') and resource ('Jira ticket'), and adds the key scope qualifier 'without updating the ticket', which distinguishes it from any tool that would actually post or modify the ticket. This makes the purpose unambiguous.

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 context for usage by emphasizing that the tool generates a comment without updating the ticket, implying it is for producing draft content rather than applying changes. However, it does not explicitly name alternative tools or state 'use this when...' but the 'without updating' phrasing effectively indicates when not to use it for direct modification.

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