TDQS

A3.7/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds genuinely new context beyond that: results are paged, and the call is free of cost, both of which affect how an agent should plan repeated calls.

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?

Extremely compact and front-loaded — the resource and returned fields come first, then the cross-tool note, then cost. The telegraphic, fragment-heavy phrasing borders on cryptic, but no sentence is wasted.

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?

An output schema exists, so return values need not be explained, and annotations cover safety. However, for a paging tool with five optional parameters, the description never explains paging semantics (how to advance from_word, what happens at the end) or what 'source number' means, leaving real gaps.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds meaning the schema does not: it clarifies that word numbers are the currency consumed by cut and source numbers by fix_captions, which explains why an agent would page through words. It still leaves 'source number' itself undefined.

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?

The description names the resource (spoken words / transcript) and the returned fields (number, start, end, source number) plus the paged nature, so an agent knows this reads transcript words. It also distinguishes itself from siblings by noting that 'cut takes word numbers' and 'fix_captions source numbers', though the verb itself is only implied by the title rather than stated in the description.

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: the mention of cut and fix_captions tells the agent how the returned word/source numbers are consumed downstream, which hints at when this tool is a prerequisite. There is no explicit statement of when to call this versus alternatives (e.g., get_timeline, get_captions-style siblings) or any prerequisites.

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