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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds real behavioral context beyond that: results are sorted newest first, each revision is broken down 'block by block', and the version values are actionable via restore_wiki_page. It stops short of documenting pagination or the limit's effect on the result size.

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 tight sentences, front-loaded with what the tool returns, with the restore tip as a natural trailing rider. Every clause carries information; nothing is filler.

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?

There is no output schema, so the description usefully carries the return shape (ordering plus the enumerated fields), which is the main completeness burden here. It leaves the limit/pagination behavior and the token parameter entirely to the schema, which is acceptable but leaves a small gap for a history-listing tool.

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 the baseline is 3, but the description adds cross-tool semantics the schema lacks: the returned revision id is what you feed to restore_wiki_page to revert the page. That linkage gives the version field operational meaning rather than leaving it a bare identifier.

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 (a wiki page's revisions) and even characterizes the payload: version, kind of change, message, author/time, and block-level diffs, ordered newest first. It is clearly distinct from read_wiki_page or save_wiki_page, though it never explicitly contrasts itself with the sibling 'history' tool, which an agent might confuse it with.

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 implied (consult past revisions of a wiki page) rather than stated, and no condition or exclusion is given relative to the sibling 'history'. The one explicit routing hint — pass a revision id to restore_wiki_page — guides what to do with the result rather than when to call this tool.

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