sync_changelog

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

With no annotations, the description carries the full burden of disclosing behavior. It explains the process (Keep a Changelog format, auto-detection, categorization) but does not mention that the tool modifies CHANGELOG.md, potential destructive overwriting, or preconditions like package.json existing. This is useful but incomplete for a mutation 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 three short, front-loaded sentences. 'Syncs CHANGELOG.md with workflow information' immediately conveys the core purpose, and the following sentences add essential detail without waste. Every sentence earns its place.

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's moderate complexity (5 optional params, no output schema, no annotations), the description provides a solid overview of what the tool does and its key behaviors. It could be more complete by mentioning side effects or when to prefer other tools, but it is sufficient for basic understanding and 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% parameter description coverage, so the baseline is 3. The description adds some context (e.g., 'categorizes changes based on feature type' relates to the category parameter) but largely repeats what the schema already documents. No additional parameter-level meaning is provided.

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 opens with 'Syncs CHANGELOG.md with workflow information,' providing a specific verb and resource. This clearly distinguishes it from sibling tools, as no other sibling targets CHANGELOG.md. Additional details like 'Follows Keep a Changelog format' further clarify its scope.

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 gives clear context: it is for syncing CHANGELOG.md with workflow data and mentions auto-detection of version and categorization. However, it does not explicitly state when to avoid using it or suggest alternatives (e.g., update_documentation), so it misses the highest tier.

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