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

The description clearly states the tool is read-only and specifies what it returns (configured repository links plus bounded sync status/activity) and what it does not expose (raw provider payloads). This aligns with the readOnlyHint and destructiveHint annotations, with no contradiction.

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 reasonably concise, using two sentences to convey purpose, usage context, and behavioral details without unnecessary verbosity. It is slightly long but every part adds value.

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?

The description provides sufficient context for an agent to use the tool correctly, including when to invoke it and what kind of output to expect. It does not describe output format in detail, but that is not required given the lack of an output schema and the simplicity of the operation.

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 schema description coverage is 100%, so the parameters are well-documented. The description does not add significant extra meaning beyond the schema, so the baseline score of 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 clearly states when to use the tool (when the user asks about repositories linked to a Space for Autopilot, repo sync, etc.) and what it does (returns configured repository links and sync activity). It distinguishes itself from sibling tools that create, delete, enable, or disable links.

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?

It explicitly gives the conditions for use ('Use this when...') and mentions the contexts (Autopilot, repo sync, suggestion generation, trigger events, recent sync activity). It does not explicitly mention alternatives or when not to use, but the intended usage is clear from the context.

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