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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is known. The description contributes useful behavioral detail about result ordering and per-item change summaries, but says nothing about result limits, pagination, or how many versions are returned.

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 short sentence with no wasted words, and the key ordering detail is front-loaded. It is borderline too terse, since the sorting and change-summary facts are the only things conveyed.

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 one-optional-parameter read tool with full annotation coverage, this is nearly adequate: it conveys the resource, ordering, and that each entry carries a change summary. It lacks any statement of scope (all versions vs. a limited window) or result shape beyond that summary, which matters since there is no output schema.

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% and the single projectId parameter is fully documented in the schema, including its default of the currently open project. The description adds no meaning about the parameter, so the baseline of 3 applies.

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 the resource (saved versions) and adds ordering and content detail ('newest first, each with what changed since the one before'), so an agent can tell it returns a version history. The verb 'list' is only implied, and it does not differentiate this from siblings like compare_versions, list_changes, or restore_version.

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?

There is no explicit when-to-use guidance, no prerequisites, and no pointer to alternatives such as compare_versions for diffing or restore_version for reverting. The agent must infer the use case entirely from the name and sibling set.

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