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

With no annotations provided, the description carries the full burden of behavioral disclosure but fails to do so adequately. It mentions actions like 'creating' and 'deleting' but doesn't clarify permissions needed, side effects, rate limits, or response formats. For a multi-action tool with potential mutations, this leaves critical gaps in understanding its behavior.

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 concise and front-loaded, consisting of a single sentence that directly states the tool's purpose without any unnecessary words. It efficiently communicates the core functionality, making it easy to grasp at a glance.

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 the tool's complexity with 12 parameters, multiple actions including mutations, and no annotations or output schema, the description is insufficient. It lacks details on behavioral traits, usage context, and output expectations, making it incomplete for safe and effective agent use.

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 description adds no parameter-specific information beyond what the input schema already provides, as schema description coverage is 100%. The baseline score of 3 reflects that the schema adequately documents parameters, but the description doesn't enhance understanding with additional context or examples.

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 clearly states the tool's purpose as a 'unified tool for listing, getting, creating, and deleting repositories,' which specifies the actions and resource. However, it doesn't differentiate from sibling tools like 'manage_workspaces' or 'manage_source' that might handle related resources, preventing a perfect score.

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?

The description provides no guidance on when to use this tool versus alternatives, such as when to choose 'manage_repositories' over 'manage_workspaces' for repository-related tasks. It lacks context about prerequisites, exclusions, or specific scenarios, offering only a basic functional overview.

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