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

The description discloses key behaviors beyond the schema: read-only access, no adminKey exposure, works in protected mode, and the semantics of each action (create returns existing link, rotate invalidates old, revoke kills, status reports). This is substantial behavioral context. However, it doesn't mention rate limits, idempotency details beyond create, or what happens if the project doesn't exist. With no annotations, the description carries the burden, and it does well but not perfectly.

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 dense but well-organized. It front-loads the core purpose and key constraint, then provides workflow guidance, then action semantics. It's a bit long but every sentence adds value. The only minor issue is that the action semantics could be more structured, but it's still clear and efficient.

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 (4 actions, security implications, workflow integration), the description covers the essential context: what the link does, how to use it in an agent workflow, and what each action does. It lacks an output schema, so it doesn't describe the return format (e.g., shareUrl field), but the description mentions shareUrl, which helps. It could also mention error cases, but overall it's quite complete.

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 coverage is 100%, so the schema already documents all parameters. The description adds meaning by explaining the action enum values (create, rotate, revoke, status) and their effects, which goes beyond the schema's simple 'Default: create.' It also clarifies that project and adminKey are required. This is a solid addition, though the schema already covers the basics.

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 the tool's purpose: mint or manage a read-only share link for a project. It specifies the resource (project), the action (share link), and the key behavioral constraint (read-only, no adminKey exposure). It also distinguishes itself from siblings by focusing on sharing for human review, which is unique among the listed tools.

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 explicitly provides an agent workflow: build or mutate a sandbox, then share_project and give the human the shareUrl. It also explains when to use it (after building/mutating, for human review) and what it does in protected mode. It doesn't explicitly name alternatives, but the workflow guidance is strong and the tool's unique purpose is clear.

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