register_repo

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. It implies a write operation ('Register') but doesn't specify permissions required, side effects, or what 'auto-sync' involves. This leaves critical behavioral traits undocumented, making it inadequate for a mutation tool.

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 a single, clear sentence with no wasted words. It's front-loaded with the core action and purpose, making it efficient and easy to understand 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 as a mutation operation with no annotations, the description is insufficient. It doesn't explain what 'registering' entails, potential outcomes, or how it interacts with other tools. While an output schema exists, the description should provide more context for safe and effective 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 doesn't mention any parameters, but with only 1 parameter (a nested object) and 0% schema description coverage, it doesn't need to compensate heavily. The schema provides detailed descriptions for the nested properties, so the lack of param info in the description is acceptable, warranting a baseline score.

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 states the action ('Register') and resource ('a repo') with a purpose ('for auto-sync'), making the basic purpose clear. However, it lacks specificity about what 'auto-sync' entails and doesn't differentiate from sibling tools like 'unregister_repo' or 'sync_status', leaving room for ambiguity.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites, such as whether the repo must be accessible or if authentication is needed, nor does it reference related tools like 'unregister_repo' or 'list_tracked_repos' for context.

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