get_transcript

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

No annotations are provided, so the description carries the full burden. It explains the behavior of all parameters, including interactions (e.g., 'include_timestamps' ignored for certain formats) and defaults. However, it does not disclose potential failure cases (e.g., invalid URL or unavailable transcript).

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 well-structured with a clear opening sentence and a bullet-style Args list. It is informative without excessive verbosity, though the Args section could be slightly condensed.

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 the presence of an output schema (not shown), the description does not need to detail return values. It covers all parameters and their behavior comprehensively. Minor missing context includes error handling and prerequisites (e.g., valid URL).

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 fully compensates by explaining all 6 parameters with defaults, accepted values (e.g., format options), and behavioral nuances (e.g., 'include_timestamps' interaction with format). This adds significant meaning beyond the schema's bare titles and defaults.

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 'Fetch a YouTube video's transcript,' which is a specific verb and resource. It distinguishes itself from siblings like 'list_transcripts' (which lists available transcripts) and 'summarize_transcript' (which summarizes).

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 description does not explicitly state when to use this tool versus alternatives like 'list_transcripts' or 'summarize_transcript.' It provides parameter details but lacks context on exclusions or prerequisites.

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