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

No annotations are provided, so the description carries the full behavioral burden; it discloses payout-address gating, referral-program effects on notice text, webhook/email delivery, and specific notice codes. It omits permission/auth requirements and whether reading acknowledges notices, but overall it is strong.

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-loads the core purpose, but the single dense paragraph packs long notice-code lists and conditional referral details without structure. It is informative but not tightly concise.

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 tool with 3 parameters, no annotations, and no output schema, the description supplies substantial context about notice types, edge cases, and delivery behavior. It is largely complete, though it omits explicit acknowledgment semantics and per-parameter guidance.

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 description coverage is 100%, and the description does not add meaning beyond agent_key, limit, or unread_only. With the schema already documenting all three parameters, the baseline 3 applies.

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 'Read this agent's notices' with a specific verb and resource, then enumerates many notice categories and event codes. It clearly scopes to this agent's notices, though it does not explicitly contrast with sibling agent_notices_ack or capability_price_notices.

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?

No explicit when-to-use or when-not guidance is given. The webhook/email note describes delivery context but does not tell the agent when to call this tool versus acking notices or using another notice-related tool.

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