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

Annotations already declare destructiveHint=true and openWorldHint=true, yet the description adds real behavioral context: this is a 'Destructive external-provider state change', it attempts webhook removal after authorization, and it stops provider events from reaching Autopilot. It also discloses the prerequisites — Enterprise access and manageable Space permission — which an agent needs before invoking a destructive, open-world 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?

Three sentences, each carrying distinct load: trigger condition, behavioral/destructive effect, and prerequisites. The user-intent trigger is front-loaded, and there is no filler or redundancy.

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 2-parameter, no-output-schema mutation tool, the description covers what an agent needs: when to call it, that it is destructive and touches an external provider, the authorization prerequisites, and the required IDs. Nothing material is missing.

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?

Schema description coverage is 100%, so both space_id and link_id are already documented in the schema with types and a pointer to list-space-repository-links. The description only restates the parameter names as prerequisites, adding no format, constraint, or ID-discovery detail beyond the schema — the baseline 3 for a fully-covered schema 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?

States a specific verb (disable) and resource (Autopilot repository link for a Space), and enumerates user-facing synonyms (pause, turn off) that map intent to the tool. It is clearly distinguishable from siblings enable-space-repository-link, update-space-repository-link, and delete-space-repository-link.

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 opening clause gives an explicit trigger condition ('Use this when the user wants to pause, turn off, or disable...'), which is strong selection guidance. It stops short of naming the alternative tools (enable/delete) or stating when NOT to use this one, so it is clear context rather than full when/when-not routing.

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