TDQS

C2.6/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Reverse a reward redemption' states the action but says nothing about side effects such as whether points are refunded, whether the redemption must be in a certain state, or whether the reversal is idempotent.

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?

The description is a single, direct sentence with no wasted words. However, it is minimal to the point of near-tautology, so while structurally clean, it provides little substance.

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

Completeness2/5

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

Given three parameters, no annotations, and no output schema, the description is under-equipped to let an agent call the tool correctly. It does not explain how to identify the redemption to reverse, what a successful reversal returns, or what failure conditions exist.

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

Parameters1/5

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

Schema description coverage is only 33%, and the tool description adds no parameter information at all. The required 'id' parameter and 'frameId' are unexplained in the description, and it does not clarify when 'category_id' is needed despite its partial schema description.

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 uses a specific verb ('Reverse') and resource ('a reward redemption'), making the tool's core action unmistakable and clearly distinct from the sibling skylight_redeem_reward. It is slightly tautological with the tool name but does convey an understandable operation.

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?

No guidance is given about when to use this tool versus alternatives, prerequisites, or situations where reversing a redemption is appropriate. The presence of siblings like skylight_redeem_reward implies the inverse relationship, but the description leaves the decision entirely to inference.

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