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

Beyond the readOnly/idempotent/openWorld annotations, it discloses that coverage comes from the site's published index rather than the API (so it costs market-data endpoints nothing), that unpublished pages are un-findable and ids are never invented, that ranking is plain lexical match, and that data is delayed/derived. It also specifies failure behavior (return last good reading with as-of time, cite on failure too) – unusually rich disclosure.

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?

Purpose and usage are front-loaded and the sentences are dense with distinct information (coverage, limits, ranking, citation rule). It is long and the citation/investment-advice tail is somewhat repetitive of earlier points, costing it a point, but almost every clause carries selection or behavior value.

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 search tool with an output schema, it covers what an agent needs: scope, return fields, handoff to fetch, exclusion of market data, freshness constraints, citation requirements, and failure handling. Nothing material for correct invocation is missing.

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 100% and both parameters are documented in the schema (including the ISO-date behavior and the 1–20 limit), so the description adds little beyond them. Baseline 3 applies; the 'pass an id to fetch' note concerns result usage, not the input parameters.

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?

States a specific verb+resource (search the pages SquawkFlow publishes) and enumerates the page types returned (glossary, methodology, calendars, filing pages, dated session records) plus the return shape (ids, titles, canonical URLs). It explicitly distinguishes itself from the sibling market-data tools that return numbers.

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?

Gives explicit when-to-use ('when you want the page that answers a question, or a citable link rather than a number'), the handoff to fetch ('pass an id to fetch'), and an explicit not-for clause ('market figures of any kind... call the tool that publishes it'). Both sides of the routing decision are named.

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