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

The description goes beyond the annotations by disclosing that this is a state-changing external-provider action, that it attempts to remove the provider webhook, and that authorization is required. This provides important behavioral context not captured by readOnlyHint or destructiveHint.

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 concise and well-structured. It front-loads the trigger condition, then provides side-effect and permission context in a compact paragraph. No unnecessary information is included.

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?

For a two-parameter tool with no output schema, the description provides all necessary context: when to use it, what it does, side effects, and required permissions. Sibling tools are not referenced, but the description is self-sufficient for correct invocation.

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?

Both parameters are fully described in the schema. The link_id description adds practical guidance by recommending list-space-repository-links first when needed, which exceeds the baseline. The space_id description is straightforward but sufficient.

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: disabling an Autopilot repository link for a Space. It uses a specific verb ('disable'), identifies the resource ('repository link'), and distinguishes the action from related operations like enabling or updating.

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 explicitly tells when to use the tool ('when the user wants to pause, turn off, or disable'), giving a clear trigger condition. It doesn't explicitly mention alternatives or exclusions, but the trigger is clear enough for an agent to select this tool.

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