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

With no annotations, the description carries full responsibility for behavioral disclosure. It transparently reveals the paid/locked nature, the two ways to unlock content, and the output structure (actionable calls with contract addresses). It does not mention rate limits or error responses, but the core behavior is well covered.

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 description is compact (approximately 70 words) and front-loaded with the core purpose, followed by parameter semantics and unlock instructions. Every sentence adds useful information without repetition or fluff.

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 7 parameters, no required fields, and no output schema, the description covers the main parameters and return behavior. It explains the premium/locked behavior and how to unlock. It omits the 'lang' parameter and does not fully detail the 'payment_required descriptor', but the description is sufficiently complete for an agent to invoke the tool correctly.

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 0%, and the description compensates by explaining the meaning and allowed values for section (HOT/SIGNALS/WARNINGS/all), asset_class, ticker, timeframe, session_token, and payment. It also explains the relationship between session_token and verify_wallet_ownership. The only parameter not described is 'lang', but its default 'en' is provided in the schema.

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 clearly identifies the resource as 'The paid Degen Digest' and its content ('actionable calls with contract addresses, grouped by section'). It distinguishes from sibling market tools by focusing on this digest and its premium nature. However, it lacks an explicit verb like 'retrieves' or 'returns', relying on the tool name to convey the action.

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 provides clear context on when to use the tool for the Degen Digest and explains the unlock mechanisms (session_token or x402 payment). It indicates that free access returns a locked teaser, which is an important prerequisite. However, it does not explicitly contrast this tool with sibling tools or specify when not to use it.

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