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

Annotations already disclose the mutation profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false), so the description's added value is the side-effect disclosure that 'stop_tracking' suppresses future alerts for that document. It does not cover permissions, whether re-rating is allowed, or what happens to the prior rating, which matters given the non-idempotent hint.

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?

Single front-loaded sentence with no filler, but it spends most of its length re-listing the six enum values already present in the schema, which is redundant rather than additive. The one genuinely useful clause is the parenthetical on stop_tracking.

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 two-parameter mutation with no output schema and a clean annotation set, the description covers purpose and the key side effect, but omits the result of rating (confirmation, persistence) and any usage conditions. It is adequate but leaves clear gaps.

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 50%: document_number is documented in the schema, but the rating enum has no schema description. The description partially compensates by glossing each value's meaning and clarifying stop_tracking, though 'more_like_this' and 'already_reviewed' are left unexplained.

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 uses a clear verb+resource construction ('Tell FedReg Tracker how relevant a document was') and enumerates the feedback actions, so the agent knows this submits relevance feedback on a document. It stops short of distinguishing itself from siblings like list_regulatory_alerts or manage_regulatory_watchlist, which are only inferable from their names.

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 by the framing (give feedback on an alert) and the semantics of the rating values, but there is no explicit when-to-use, when-not-to-use, or alternative routing. An agent must infer that this is the write-side counterpart to the alert-listing tools.

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