youtube.transcript.analyze

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

With no annotations, the description must fully disclose behavioral traits. It does not state whether the tool is read-only, requires authentication, has rate limits, or what side effects occur. The lack of output schema further obscures what the agent should expect. The description only hints at the analysis dimensions.

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, focused sentence that conveys the core functionality without any extraneous words. It is appropriately sized and front-loaded.

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 lack of output schema and annotations, the description is insufficient for an agent to fully understand the tool's behavior and output. It does not cover return value format, error conditions, or any constraints beyond the input schema details. More context is needed for reliable usage.

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 0%, so the description should compensate for parameter meaning. It mentions 'hook, structure, CTAs, and retention signals' which partially correspond to the 'analysisTypes' enum (hook, structure, cta, repurpose), but 'retention signals' is not in the enum, causing potential confusion. 'transcriptText' is not described at all.

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 tool's purpose: analyzing a transcript for hook, structure, CTAs, and retention signals. The verb 'analyze' and resource 'transcript' are specific, and the focus areas are listed. However, it doesn't explicitly differentiate from sibling tools like 'youtube.transcript.get', which retrieves transcripts, but the distinction is implicit.

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 on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a transcript from 'youtube.transcript.get'), nor does it specify when not to use it. The agent is left without context on tool selection.

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