TDQS

B3.2/5.0
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 behavioral burden, and it does not say whether the call requires an authenticated session, whether it is idempotent, what happens if the user was not blocked, or what errors are raised. For a mutation tool with zero annotation coverage this is a notable gap.

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?

A single front-loaded sentence that names the action and the target identifier with no padding. It is appropriately sized for a one-parameter tool, though it is too sparse to earn a 5.

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-value explanation is not required, and the tool's operation is simple. Still, with no annotations and no error/idempotency behavior described, an agent lacks needed context for edge cases.

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?

One required parameter at 0% schema description coverage, so the description must lean in: 'by user ID' confirms what user_id identifies and that the target is looked up by ID rather than username. That is marginal added meaning over the self-explanatory schema key, but not zero.

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?

States a specific verb ('Unblock') and resource ('a previously blocked user'), and the unit of identification ('by user ID'). This clearly separates it from bale_block_user and bale_get_blocked_users, though it never names those siblings explicitly.

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 implied by the reverse-of-block semantics; an agent can infer when to call it. However, there is no explicit guidance on prerequisites (e.g., auth/session state) or a named alternative such as bale_block_user, so it settles at implied rather than stated.

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