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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds real behavioral content the annotations do not: it parses specific file types and returns the checklist items of all upgrade notes up to the target, and the schema notes target defaults to the latest release.

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 dense sentence with the primary action front-loaded and no filler. It is slightly packed — the file list and the return content are compressed into one clause — but nothing is wasted.

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?

No output schema exists, and the description does state the shape of the return (checklist items from every upgrade note up to the target), which covers the main gap. Defaults and per-parameter meaning are handled by the schema, so an agent has enough to call it.

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 all three parameters are already documented in structured form. The description only lightly reinforces the files-vs-current duality ("or takes it as given") without adding syntax or precedence rules beyond 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?

Uses specific verbs (finds, lists) on a concrete resource (Claspine version in named project files / upgrade-note checklist items). That is clearly distinct from upgrade_notes and check_config in substance, but the description never names a sibling to make the distinction explicit.

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?

"or takes it as given" implies two input modes (files vs. current), which is useful context. However, there is no statement of when to call this rather than upgrade_notes or get_guide, and no exclusions or prerequisites.

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