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

The annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered without description help. The description adds a permission constraint ('one authorized item'), which is useful context, but says nothing about ordering, pagination, or how much history is 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?

One sentence, front-loaded with the action and resource, with no filler. It is arguably too terse for a history tool, but nothing in it 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?

For a simple single-parameter read tool with a fully documented schema and no output schema, the description covers the essential what. It is still thin for a history operation: an agent cannot tell whether results are paginated, sorted, or capped, which are the questions a history call usually raises.

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% for the single 'id' parameter, including the pattern and the note that it accepts an item ID or a task reference like TASK-12. The description's phrase 'one authorized item' adds no syntax or format detail beyond what the schema already states, 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 gives a specific verb ('read') and resource ('revisions and attribution') scoped to a single item, so the agent knows this retrieves change history rather than task or note data. It does not, however, distinguish itself from the similarly-named sibling get_activity, which an agent could reasonably confuse with revision history.

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: 'one authorized item' hints that this applies to a single known item rather than a listing, and the sibling set contains alternatives like get_activity and get_notes. No explicit when-to-use, when-not-to-use, or named alternative is provided, leaving the agent to infer the choice.

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