TDQS

A4.2/5.0
Behavior4/5

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

Beyond the annotations, the description discloses a behavioral consequence: activity from the interest stops appearing in the catch_up feed. It also scopes the action to previously joined interests, adding operational context while remaining consistent with the idempotent, non-destructive hints.

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?

The description is a single, tightly written sentence that front-loads the action and follows with the most relevant consequence. No words are wasted, and the structure supports quick comprehension.

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 two-parameter tool with complete schema coverage and informative annotations, the description sufficiently explains the action, its precondition, and its effect. It does not discuss errors or return values, but those are not essential for this straightforward operation.

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 the schema already documents both parameters, including interest_id as 'The interest to leave'. The description adds no additional parameter-level detail, but this is acceptable given the complete schema coverage.

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 ('Leave') and resource ('an interest area you previously joined') and explains the concrete effect on the user's catch_up feed. This clearly distinguishes it from sibling tools like join_interest, browse_interests, and unendorse_interest.

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?

It provides clear context for when to use the tool: when leaving an interest area the user previously joined, with the consequence that its activity disappears from the catch_up feed. It does not explicitly name alternatives or exclusion cases, but the context is sufficient to route an agent correctly relative to join_interest.

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