TDQS

A4.5/5.0
Behavior4/5

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

The description adds context beyond the annotations by clarifying that the position is read from the active sequence and refers to the CTI. The readOnlyHint, idempotentHint, and destructiveHint already cover side-effect expectations, so the added scope is sufficient. It does not mention behavior when no active sequence exists, but that is a minor gap.

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

Conciseness5/5

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

A single, direct sentence with no filler. It front-loads the action and resource, and every word earns its place by specifying current, CTI, and active sequence.

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

Completeness5/5

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

For a zero-parameter, read-only tool with an output schema, the description is complete. It identifies the target context (active sequence), what is read (CTI position), and the annotations cover safety and idempotency. No critical missing information is needed for correct invocation.

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?

This tool takes zero parameters and the schema is empty with 100% coverage. Per the rubric, zero parameters earns a baseline of 4; there is no parameter meaning for the description to add.

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

Purpose5/5

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

The description states the specific verb 'Get', the resource (current playhead/CTI position), and the context (active sequence). It clearly distinguishes itself from sibling tools like set_playhead_position (get vs set) and get_work_area (playhead vs work area).

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

Usage Guidelines4/5

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

The description makes the usage context clear: use this when you need the current playhead position in the active sequence. It does not explicitly name alternatives, but no sibling tool has exactly the same purpose, and the scaffold (get vs set, timeline vs source monitor) is unambiguous.

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