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

With no annotations, the description carries the full burden of behavioral disclosure. It does add useful context: filing is free, earnings are 90% on-chain after X-PAYMENT, and an empty call returns a template. However, it never explains what 'sealing' does as a side effect, whether filing is reversible, what X-PAYMENT means, or what happens after submission. The undefined X-PAYMENT token is a notable transparency gap.

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 sentences with minimal waste: purpose, cost, template path, and usage timing are all present and front-loaded. The main deduction is for unexplained jargon ('X-PAYMENT', 'packet fields'), which forces the reader to infer meaning rather than making the concise text self-contained.

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 10 parameters, nested objects, no output schema, and no annotations, the description is far from complete. It does not explain what the API returns, what makes a valid packet beyond the schema's own body description, how X-PAYMENT affects earnings, or which fields are essential. An agent would need to call /api/template to understand the tool meaningfully.

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 only 10%, so the description must compensate, but it does not. It mentions 'packet fields' generically and suggests that an empty call returns /api/template, which hints at optionality, but it provides no meaning for any of the 10 parameters, including important ones like body, priceUsd, or provenance.

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 states a specific action—'sealing completed research'—and a concrete outcome ('Earn Base USDC'). It distinguishes itself from siblings like earnings and status by focusing on submission rather than viewing or unlocking. However, 'sealing' is somewhat jargon-heavy and could be clearer that this is the tool for filing a research packet.

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?

The description gives clear contextual guidance: 'Prefer this after expensive sessions before ending.' It also explains a usage pattern: call with packet fields or empty to get /api/template. It does not explicitly name alternatives or exclusions, but the timing guidance is actionable enough to rate above a bare minimum.

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