TDQS

A3.6/5.0
Behavior3/5

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

The description adds some context beyond the annotations by specifying that the tab (not the sequence data) is what gets closed, which mitigates confusion with delete_sequence. However, it does not elaborate on the destructive implications flagged by destructiveHint=true — e.g., whether unsaved state is lost or whether the sequence remains available after closing.

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, front-loaded sentence with zero filler. The core action ('Close a sequence tab') appears first, followed by the location ('in the timeline'), which is all the description needs.

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

Completeness4/5

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

For a simple one-parameter tool with an output schema and 100% schema coverage, the description covers the essential operation. The only notable gap is not clarifying the distinction between closing a tab and deleting a sequence, given the destructiveHint=true annotation.

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?

The description adds no parameter information, but schema description coverage is 100% — the schema already documents that sequence_id accepts a name or ID and defaults to the active sequence. Per the baseline for high coverage, a 3 is appropriate.

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 uses a specific verb+resource pair — 'Close a sequence tab in the timeline' — which precisely distinguishes it from sibling tools like delete_sequence (removes the sequence), close_project, and close_source_monitor. The mention of 'tab' signals a UI-level operation, not data deletion.

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

Usage Guidelines2/5

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

The description gives no guidance on when to use this tool versus its many siblings. Notably, it does not clarify when to use close_sequence instead of delete_sequence, close_project, or close_source_monitor, nor does it address the destructiveHint=true annotation by explaining the consequences of closing a sequence tab.

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