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

With no annotations, the description must carry the full burden of behavioral disclosure. It does well by specifying the short-lived (~1h) nature, read-only vs. write-scoped access, the fork push flow, and the API key requirement. It does not mention error handling or response format, but the disclosed details are substantial and relevant.

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 yet complete, covering private repos, public repos, fallback, and requirements in four sentences. Each sentence adds distinct value, and the structure clearly differentiates scenarios. No fluff 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?

The description covers the key behavioral aspects: access provisioning, scoping, fallback, and prerequisite. It does not describe the return format or usage of the minted URLs, which would be helpful given no output schema, but the core functional context is sufficiently explained for a tool of this complexity.

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 already provides 100% coverage with descriptions for both parameters ('task_id' and 'agent_id'). The description adds context by linking task_id to code-task repos and clarifying the attribute purpose of agent_id, but it does not materially extend the schema's parameter semantics. Baseline 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 explicitly states the tool's function with a specific verb ('mint') and resource ('repo access'), covering both private and public repository scenarios. It clearly distinguishes itself from sibling tools by focusing on repo access provisioning rather than bounty management or submission.

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 provides clear context for when to use the tool: for private repos it offers a read-only clone and optionally a managed fork; for public repos it indicates normal fork behavior. It also notes the patch upload as a fallback, giving practical guidance. However, it does not explicitly name alternative tools to use instead, so it stops short of a 5.

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