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

With no annotations, the description carries the full behavioral burden, and it does disclose two real traits: result ordering (newest first) and default scope (drafts included). It says nothing about return shape, whether results are paginated beyond the limit cap, or that the operation is a side-effect-free read.

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?

A single sentence, front-loaded with the verb and resource, with the useful scope facts packed into a trailing clause. No filler or redundancy.

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 two-parameter read with complete schema coverage and no output schema, the description covers purpose, ordering, and default draft inclusion – enough to call it correctly. Only the semantics of combining the "including drafts" default with a status filter is left implicit.

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 both parameters (limit with default/max, status enum) are already fully documented, establishing a baseline of 3. The description adds no parameter-level detail beyond implying the unfiltered default includes drafts, which is inferable from the optional status param.

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 uses a specific verb+resource ("List the project's changelog entries") and adds scope qualifiers ("newest first, including drafts") that tell the agent exactly what a call returns. Sibling tools are all feedback- or create-oriented, so no explicit differentiation is needed or supplied.

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?

Usage is only implied by the verb: any time an agent needs to browse changelog entries. There is no explicit statement of when to prefer this over a filtered lookup or how it relates to create_changelog_entry, and the interaction between the default "including drafts" and the optional status enum is left for the agent to reconcile.

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