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

There are no annotations, so the description carries the full burden of explaining behavior. It says the tool reformats and standardizes, but it does not disclose whether it returns the reformatted text, modifies anything in place, requires the api_key, or what 'best practices' entails. The ambiguous '(Pro)' suffix adds no useful behavioral detail.

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, short sentence with the core action front-loaded. It is concise and readable, though the '(Pro)' qualifier is somewhat ambiguous and the phrase 'standardize ... best practices' is slightly redundant with 'reformat'.

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 transformation tool with no output schema and no annotations, the description leaves important gaps: it does not explain the return format, whether the tool writes back to a file, how the format parameter influences output, or authentication expectations. The existing schema covers parameters but not the behavior or result of the operation.

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 three parameters already have clear descriptions in the schema. The tool description itself adds no parameter-level detail, and the baseline of 3 applies because the schema carries the semantics sufficiently.

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 (reformat and standardize) and the resource (an existing changelog). It distinguishes itself from sibling tools like changelog_from_commits and changelog_from_prs by specifying 'existing' content, though it does not explicitly name those alternatives.

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 phrase 'existing changelog' implies the tool is for reformatting content the user already has, not for generating changelogs from commits or PRs. However, it does not explicitly state when to prefer this tool over alternatives or provide any exclusions.

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