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

Beyond the readOnly/openWorld annotations, the description discloses concrete operational behavior: an unconfirmed alert answers 403 alert_unconfirmed unless include_unconfirmed is true, and the default route is free only for confirmed alerts. The payment model (x402, API key, or wallet token on a paid plan) is stated, which is exactly the kind of auth/cost context annotations cannot express.

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?

The core provenance and 403 behavior is front-loaded in the first two sentences, which is good. The trailing parenthetical then restates the free/paid conditions already given, making the passage denser than necessary.

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 read tool with no output schema, the description covers the response contents, id provenance, the error case, and the payment gate. An agent has everything needed to call it correctly and to anticipate the 403 outcome.

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 100%, so the baseline is 3, but the description adds value the schema lacks: it states that include_unconfirmed defaults to false, that the false route is free for confirmed alerts, and that the true route is paid and unlocks suspected alerts. The uuid format of id and the article_id alternate form are already in the schema, so the addition is meaningful but incremental.

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 resource (one exchange security alert) and lists what it returns (evidence signals, sources, timeline), which clearly distinguishes it from the sibling list tool muhabbit_alerts. The retrieval verb is implied by the noun phrase plus 'Takes the id from...' rather than stated outright, so it falls just short of a fully explicit verb+resource statement.

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?

It explicitly tells the agent where the identifier comes from — an id from muhabbit_alerts or the article_id of a headline in muhabbit_events — which is exactly the routing information needed. It gives no explicit 'do not use when' case (e.g., when browsing multiple alerts), but the provenance guidance is clear and actionable.

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