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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety behavior is covered. The description adds that results are scoped to reachable tools and returned as TypeScript declarations, which is useful output-shape context. But it explicitly punts the 'full contract' to server instructions rather than disclosing it here, limiting added value.

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?

Two sentences, front-loaded with the core purpose. The deferral to server instructions is efficient but slightly hand-wavy; no wasted words otherwise.

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?

An output schema exists, so return values need not be explained here, and annotations cover safety. The result shape (TypeScript declarations) and scope (reachable tools) are stated. The main gap is the deferred contract, but overall complete enough to call correctly.

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% and the query parameter is fully documented in the schema (case-insensitive substring, omit for all). The description adds no parameter detail beyond the schema, so 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?

States a specific verb (Find) and resource (BioFlow MCP tools this connection can reach), and specifies the output format (TypeScript declarations for execute_typescript). This clearly distinguishes it from the sibling execute_typescript, which it feeds into.

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 usage—find tools, then call them from execute_typescript—which sets up a workflow with the sibling. However, it gives no explicit when-to-use or when-not-to-use guidance, and defers the contract to server instructions rather than stating it. Usage context is implied but not spelled out.

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