TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description adds the 'public URL' precondition and reveals that only a transcript 'excerpt' is returned, but it never discloses the payment gate implied by x402_payment unlocking the 'full payload' — a significant behavioral fact left to the schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with zero filler, but the comma-separated output list is dense enough that the partial-vs-full payload distinction is easy to miss.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description carries the burden of explaining return values; it enumerates the fields but not their shape, excerpt length, chapter format, or what the paid tier adds. For a tool whose default output is truncated, that is a meaningful gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters are already documented in structured fields and baseline is 3. The description restates the URL requirement without adding format, accepted-host, or length guidance, and says nothing about when or how x402_payment should be supplied.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb ('Extract') plus the exact artifacts returned: video title, channel, timestamped chapters, transcript excerpt, and 3 viral hook angles, scoped to public https:// YouTube/video URLs. No sibling in the listed set is a media/transcript tool, so the resource itself distinguishes it, though the description never explicitly contrasts with anything.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied by the 'public https:// YouTube/video URL' constraint; there is no explicit statement of when to pick this tool, no exclusions (e.g. private/age-gated videos), and no named alternative for related tasks.

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