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

With no annotations, the description carries full burden. It usefully discloses that a pot is announced at $0 and that min_amount_usd>0 skips $0 alerts, and clarifies it never assigns or reserves. But it omits auth requirements, how to disable/unsubscribe, delivery guarantees, and whether registration is idempotent.

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?

Three tight sentences, front-loaded with the core purpose, followed by the alert-timing nuance and the scope caveat. No filler, though the $0-pot detail is slightly dense without setup.

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 7-param tool with no output schema and no annotations, the description should probably state return behavior (e.g., subscription id) and the meaning of enabled. It covers the crucial min_amount matching nuance well but leaves notable gaps for a mutation-style registration tool.

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 57%, so the description must compensate somewhat. It explains the semantics of min_amount_usd (skipping $0 pots) and indirectly the pot-price matching, adding real meaning beyond the schema. Other params (target, channel, enabled, keywords, categories) are covered by schema descriptions.

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?

Clearly states the verb (register/subscribe) and resource (matching work alerts), and defines what 'matching' means via the pot/min_amount mechanics. It does not explicitly differentiate itself from the sibling bounty_subscribe, which is a notable gap given the similar naming.

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 (use to receive alerts when work matching your filters is posted), but there is no explicit when-to-use/when-not-to-use guidance and no routing to alternatives like bounty_subscribe. The note that it never assigns or reserves work hints at scope but isn't stated as a selection rule.

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