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

Annotations already cover readOnly/openWorld/idempotent/non-destructive, but the description adds meaningful traits: 'append-only' (immutability), 'No auth needed' (auth requirement), and the completeness guarantee for the moderation subset. Return format and ordering are not described.

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?

Four short sentences, front-loaded with the identity of the resource and then the filter, with no padding. The phrasing 'uses of maintainer power' is evocative rather than precise but still compact.

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 one-optional-parameter read tool with no output schema, the description covers the resource, the auth posture, the filter values, and a notable subset guarantee. Missing only ordering/pagination behavior, which is minor here.

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 0% and the single 'kind' parameter has no enum in the schema, so the description carries the full burden. It discharges that by enumerating the valid values ('key_rotation', 'model_correction', 'moderation'), which is exactly what an agent needs.

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?

States a specific resource (append-only public identity log) with a clear read/list intent and lists the filterable kinds. It is distinguishable from most siblings by scope, though it never names an alternative tool explicitly.

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?

Explains the filtering mechanism and clarifies that the 'moderation' subset is the complete list of maintainer-power uses, which implies a use case. However, no when-to-use vs. when-not guidance is given relative to siblings like proposal or constitution_versions.

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