Generate Release Notes

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

Annotations already provide readOnlyHint, idempotentHint, destructiveHint. The description adds useful behavioral context: 'Repository text is treated as untrusted' implying security precautions. It also clarifies the output is a 'draft'. No contradictions with annotations.

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 sentences: first establishes purpose and relationship to ref comparison, second adds security context. Every sentence adds value, no wasted words.

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 tool has 5 parameters, no output schema, and no parameter descriptions, the description is incomplete. It lacks info on return value format, error conditions, or parameter constraints. Annotations partially mitigate safety concerns, but usage details are sparse.

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 0%, so the description must compensate. However, the description provides no details about parameters (project_id, from_ref, to_ref, limit_commits, output_format) beyond what the schema names suggest. Users must infer semantics from parameter names alone.

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 and resource: 'Generate draft release notes from repository compare results between two refs.' It clearly distinguishes itself from sibling tools like 'gitlab_compare_refs' by indicating it produces release notes from comparison results, and adds the security note 'Repository text is treated as untrusted.'

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 after performing a ref comparison but does not explicitly state when to use it versus alternatives such as 'gitlab_get_release' or 'gitlab_list_releases'. There is no when-not-to-use or alternative guidance.

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