github_users_unblock

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

Without annotations, the description carries the full burden. 'Unblock a user' implies a mutation but does not disclose effects (e.g., what happens if user is already unblocked, required permissions, side effects). This is insufficient for an agent to fully understand the operation.

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

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

The description is extremely short (two words) with no wasted text. While it is concise, it may be too terse, but it adheres to the principle of being front-loaded and minimal.

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

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

Given no annotations, no output schema, and a single parameter, the description lacks necessary context such as authentication requirements, return values, error handling, or whether the operation is reversible. It is incomplete for an agent to use confidently.

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

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

The input schema has one parameter 'username' with description 'username', giving 100% schema coverage. The description adds no additional meaning beyond what the schema already provides, so baseline 3 is appropriate.

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

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

The description 'Unblock a user' clearly states the action (unblock) and the resource (a user). It is specific and uses a strong verb. However, it does not differentiate from sibling tools like github_orgs_unblock_user or indicate the context (e.g., unblock from the authenticated user's blocked list).

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

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

No guidance is provided on when to use this tool versus alternatives such as github_users_block or github_orgs_unblock_user. The description does not mention prerequisites, scope, or when not to use it.

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