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

With no annotations, the description carries the full burden and does supply substantive behavior: HMAC-SHA256 signing with an X-SolvScore-Signature header, a returned secret required for unsubscribe/status, a 6-hour re-scoring cadence, and a top-48 roster scope. It does not clarify whether the tool itself performs these calls or merely documents them, which is the one behavior an agent most needs.

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?

Front-loaded with the free-tier marker and the core trigger condition, then moves to concrete endpoints and payloads. The URL and body excerpts are dense but earn their place given the empty input schema.

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?

An output schema exists, so return values need not be explained, but the description never states what this specific 0-param tool produces — a summary of the alert API, subscription state, or something else. For an info-style tool whose entire value is its response, that omission leaves a real gap.

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?

The tool takes zero parameters, so the baseline is 4. The description usefully notes the payload shape an agent would need for the underlying endpoints (agent id/name, webhook_url), even though those are not schema parameters here.

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 identifies the subject (SolvScore webhook alerts) with concrete detail — triggers, signing scheme, cadence — but it describes the underlying HTTP service rather than what this zero-parameter tool actually does or returns. An agent cannot tell whether calling solv_alerts_info subscribes a webhook, returns documentation, or fetches status; nothing distinguishes it from solvscore_decision_info or solvscore_repgate.

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 statement of when to call this tool versus the many solvscore_* siblings, and no exclusions. The subscribe/unsubscribe/status HTTP flows are described, but as endpoints to POST to, not as conditions for invoking the tool.

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