get_pulse_narratives

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

The description thoroughly discloses unusual behavioral traits: the $0.01 x402 payment, USDC on Base settlement, the compute-first/settle-after error policy, the PRIVATE_KEY requirement, and the return of 402 price terms without a key. Since no annotations are provided, this transparency is essential and well-executed.

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 somewhat repetitive, mentioning payment twice ('PAID $0.01 via x402' and 'Pays USDC on Base via x402'). It also buries the core purpose after billing information, making it less front-loaded than ideal. Still, it is brief and covers necessary points.

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 no-parameter tool with no annotations and no output schema, the description covers the essential operational aspects: what is returned, payment mechanics, error handling, and setup. It does not describe the output structure, but for a simple list-like tool this is acceptable.

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?

There are zero parameters, so no parameter explanation is needed. The baseline for zero-parameter tools is 4, and the description adds no unnecessary parameter details.

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 the resource as 'Active AI-business narratives with lifecycle stage and momentum,' and the tool name 'get_pulse_narratives' indicates retrieval. It distinguishes from the sibling 'get_pulse_narrative' by implying a collection of active narratives, though it lacks an explicit verb like 'retrieve' or 'list'.

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 guidance is provided on when to use this tool versus alternatives such as get_pulse_narrative or get_pulse_digests. The description mentions payment setup and fallback to 402 terms but does not specify use cases or exclusions.

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