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 fully covered elsewhere. The description adds almost no behavior of its own: it says nothing about ordering (newest first?), pagination behavior via limit/cursor, maximum page size, or what a revision entry contains, which matters for a list endpoint.

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?

It is a single front-loaded sentence with no redundant wording, which is structurally clean. However, the brevity comes at the cost of substance rather than being earned conciseness, so it sits at minimum viable.

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 paginated list tool with three parameters, 0% schema coverage, and no output schema, the description should at least explain pagination and result ordering or shape. It omits all of that, leaving the agent unable to predict paging behavior or how to traverse a multi-page history.

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 0%, so the description carries the full burden for all three parameters, and it documents none of them. The phrase 'of a request' weakly implies that spec_id scopes the listing, but limit and cursor (pagination) go entirely unexplained in both schema and description.

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 verb and resource ('Lists every saved version of a request'), which is enough to distinguish it from the singular get_spec_revision and from get_spec/list_specs. It loses a point for calling the resource a 'request' while the schema's key is spec_id, leaving a small terminology gap the agent must bridge itself.

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 guidance on when to call this versus get_spec_revision (single revision), get_spec (current state), or list_specs. The only implied usage is that the agent already has a spec_id, and nothing is said about exclusions or prerequisites.

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