get_pulse_content_recent

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

With no annotations, the description carries the full burden and does well by disclosing the paid nature ($0.02), compute-first settle-after guarantee ('never charged for an error'), and the behavior without a key (returns 402 price terms). This goes beyond the schema and helps set expectations.

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 three sentences long and every sentence adds critical information (cost, resource, payment behavior). It is reasonably front-loaded, though leading with pricing might be less intuitive than leading with what the tool returns.

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 zero-parameter tool with no output schema, the description covers the essential context: what it returns, the time window, cost, payment setup, and error behavior. It does not specify the output format, but that is a minor gap given the tool's simplicity.

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?

The input schema has zero parameters, so the baseline is 4. The description does not need to explain parameters but does mention the PRIVATE_KEY environment variable, which is relevant for usage. No additional param semantics needed.

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 ('raw scraped content items') and a specific scope ('last 4 hours'), which differentiates it from siblings like get_pulse_narratives or get_pulse_digests. Though the verb is implied rather than explicit, the tool name 'get' plus the description make the action clear.

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 time window ('last 4 hours') implies usage for recent content, but there is no explicit guidance on when to use this tool versus alternatives or when not to use it. The payment and setup details provide context but not selection guidance.

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