A4.5/5.0
Behavior5/5

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

Annotations only cover the generic safety profile; the description adds real operational context beyond them: a $0.10/30-day charge, a test message sent first with failed tests left unpaid, and a hard cap of 20 messages per hour. These are behaviors an agent could not infer from structured fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Pricing is front-loaded, then the when-to-use clause, then input shape, then test-message and rate-limit details. Every sentence carries distinct information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a paid, open-world mutation tool with a full schema and an output schema, the description covers cost, auth/destination handling, test semantics, and rate limits. Nothing needed to invoke it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents destination syntax, kinds enum, and all filter parameters. The description restates destination format and 'kinds' but adds no syntax or constraint information the schema lacks; baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource (subscribe for push alerts to Discord/Telegram) with concrete scope: pump.fun and Robinhood Chain alerts, no server required. No sibling tool does push delivery, so the agent can distinguish it immediately from the query-style tools in the list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear triggering condition: 'Use when a Discord or Telegram room you own should get pump.fun and Robinhood Chain alerts without a server.' It does not name alternatives or exclusions, but the condition is specific enough to route correctly.

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