changelog_finalize

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description only needs to add context. It adds 'receipt-backed' and 'end-of-task' scope, but does not explain what 'receipt-backed' means or what the rendered output should look like.

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 with no filler. It places the most important scope information—'receipt-backed end-of-task'—before the noun, making it easy to parse quickly.

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 3-parameter tool with no output schema and no parameter descriptions, this is too thin. An agent still cannot tell what qualifies as a receipt, why receipts are optional despite 'receipt-backed' language, or what the rendered changelog entry will contain. The annotations cover safety but not the call contract.

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 carries the burden for parameter meaning, but it only hints at receipts with 'receipt-backed' and says nothing about title or changes. Title and changes are somewhat self-evident, and the receipt hint provides partial value, but the description is not enough to compensate for the lack of schema descriptions.

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: 'Render a receipt-backed end-of-task changelog entry.' The 'end-of-task' qualifier and tool name distinguish it from the sibling changelog_intake, though it does not explicitly name that alternative.

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?

'End-of-task' implies this tool belongs at task completion, and 'finalize' signals the final changelog step. However, it does not explicitly say when to use this tool versus changelog_intake or any other sibling, leaving the usage guidance mostly implicit.

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