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

Annotations already declare this a safe, idempotent read. The description adds ordering ('oldest first') and the shape of the content returned, which are useful behavioral details beyond the annotations. Minor gaps remain around whether the range is inclusive and how results are bounded.

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?

Two sentences, no filler, and the ordering/content summary is front-loaded ahead of the actionable instruction. 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?

With no output schema, the description usefully explains what the notes contain and their order. It is nearly complete for a simple two-parameter read tool, lacking only clarification of range inclusivity and any result limits.

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 coverage is 100%, so both parameters are already documented, including the default for 'to'. The description's 'after one version up to another' hints at range semantics but is ambiguous about whether 'from' is exclusive, adding little over the schema.

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 names a specific resource (Claspine upgrade notes) and scope (between two versions), with content described (changes, checklist, pre-deploy steps). It clearly separates itself from docs-oriented siblings like api_reference or get_guide, though it does not explicitly name a sibling tool.

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?

'Read them all before changing the Claspine version' gives a clear trigger for use. It doesn't mention alternatives (e.g., check_upgrade) or when not to use it, so it falls short of the explicit routing a 5 requires.

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