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

Given no annotations, the description carries full burden. It discloses key behaviors: verification_ref is required, project_id is immutable, and only verified conservation is funded. However, it does not mention side effects, authorization needs, or rate limits.

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: three sentences with no redundancy. It front-loads the purpose and then adds key constraints. Minor improvement could be to separate parameter details more clearly.

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?

With 7 parameters, no annotations, and an output schema (not shown), the description covers core purpose and constraints but lacks parameter semantics and guidance on idempotency or error scenarios. It meets minimum completeness for a creation tool but leaves gaps.

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 description coverage is 0%, so the description must explain parameters. It only adds meaning for project_id (immutable) and verification_ref (required). The other 5 parameters (name, location, beneficiary, methodology, registry_ref) are not explained, leaving the agent without guidance on optional fields.

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 registers a verified restoration project for funding retirements. It uses specific verb-resource pairing ('Register a VERIFIED restoration project') and the context of sibling tools like book, buy, list confirms it's distinct.

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 implies the tool is for initial project registration before funding, but it does not explicitly state when to use it versus alternatives (e.g., list_projects for viewing). No exclusion criteria or when-not-to-use guidance is provided.

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