List FRED releases

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

The readOnlyHint and openWorldHint annotations already establish a safe read operation. The description adds little beyond stating the tool lists releases; it does not disclose that the result is paginated via limit/offset, and the word 'all' is potentially misleading since the default limit is 1000. No contradiction with annotations, but the added behavioral context is minimal.

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 a single sentence with a brief example, containing no fluff. It is front-loaded and efficient, earning a perfect score for conciseness.

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?

Given six parameters and no schema-level descriptions, the description is insufficiently complete. It fails to mention pagination, ordering options, or date filtering, leaving significant operational gaps that the output schema does not cover.

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?

With 0% schema description coverage, the description needed to explain all six parameters. It only offers 'limit=20' as an example, giving minimal insight into that parameter while leaving offset, order_by, sort_order, realtime_start, and realtime_end unexplained.

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 states the verb and resource: 'List all FRED releases of economic data.' The scope qualifier 'all' hints at differentiation from sibling tools like get_release, though it does not explicitly name alternatives, so it stops short of a 5.

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 about when to use this tool versus alternatives such as get_release or list_release_dates. The example 'list_releases(limit=20)' illustrates a call but does not explain the appropriate context or exclusions.

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