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

Description discloses that it is a state-changing action, that it enables the link and registers a provider webhook after authorization, and lists required permissions (Enterprise access, manageable Space permission, provider access). This goes beyond the annotations (readOnlyHint false, destructiveHint false) by detailing side effects and permission needs.

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?

Description is concise and well-structured, covering purpose, when to use, side effects, and permissions in two sentences without 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?

Given the tool's moderate complexity (state-changing, external provider integration, permission requirements), the description provides sufficient context for correct invocation. No output schema exists, so no need to describe return values. It also clearly distinguishes from sibling enable/disable tools.

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 covers both parameters (space_id, link_id) with clear descriptions. The tool description mentions them but adds no extra meaning beyond confirming they are required. Baseline score of 3 since schema coverage is 100% and no additional parameter info is provided.

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?

Description clearly states the verb 'enable' and the resource 'repository sync link' for a Space, and distinguishes from sibling tools like disable, create, update, and delete by specifying 'turn on or resume an existing' 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?

Explicitly says when to use this tool ('when the user wants to turn on or resume an existing...'), which directly contrasts with sibling tools like create or disable. It implies not for new links, and the requirement for 'existing' differentiates it clearly.

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