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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered; the description adds ordering (newest first), page size (50), and the data provenance (free data from AlphaGrowth). It does not cover rate limits or how deep pagination realistically goes, so it is strong but not exhaustive beyond the annotations.

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?

Front-loaded with the resource and return shape, then the two actionable routing hints. It is dense with no filler, though the first sentence is a long comma-laden run-on that could be split for faster scanning.

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 two-optional-parameter read tool with no output schema, the description supplies everything needed: what is returned per item, ordering, page size, and where to go for transcripts. Nothing an agent needs in order to call it correctly 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%, so both parameters (page, query) are already documented, including the 50-per-page meaning. The description largely restates the same semantics ('Search titles and summaries with query') rather than adding syntax, matching rules, or edge-case behavior, so baseline 3 applies.

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?

Names a specific resource (recorded and transcribed crypto X Spaces) and enumerates exactly what each record contains: title, date, duration, AI summary, speakers. It also distinguishes itself from the sibling 'space' tool by stating that transcripts and Q&A live there, not here.

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?

Explicitly routes two cases: use 'query' to search titles and summaries, and use 'space' to read a recording's transcript and Q&A. That is a clear alternative pointer, but there is no explicit statement of when not to use this list tool (e.g. browsing vs. targeted lookup), so it stops short of full 5.

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