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

Annotations cover the safety profile (not read-only, openWorld, idempotent, non-destructive), and the description adds real behavioral context on top: the Authorization: Bearer token requirement, what returns immediately (Base and Solana wallets, USDC-capable, x402-payable), that no banking verification or fee is needed, that the verification link is optional with ~2-minute approval, and the concrete idempotency semantics ('returns the same account rather than making a second one').

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 purpose is front-loaded in the first sentence and the density of actionable facts is high. It is on the long side and mixes in promotional framing ('no fee', 'x402-payable'), but nearly every clause carries information an agent needs before calling.

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 no output schema, the description carries the full burden of describing returns and it does: wallets, the optional verification link, and the onboarding_token required by later calls. Combined with the auth requirement and idempotency semantics, an agent has everything needed to invoke this 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 description coverage is 100%, so both parameters (email, phone) are already documented in the schema, which sets the baseline at 3. The description does not add format detail for either parameter beyond the schema, though it does disclose a non-schema requirement (the Bearer header) that is not a parameter.

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 a specific verb and resource: sign in with a verified email and open or reconnect a Glide account, returning wallets, a verification link, and an onboarding_token. That is far more specific than the bare name, but it never names a sibling (e.g. get_wallets or check_status) to distinguish itself from, so it lands at 4 rather than 5.

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?

It gives clear conditions for use: call it to open or reconnect an account with a verified email plus a Privy Bearer token, and use the verification link only for bank rails. It also notes the call is safe to repeat with the same email. It stops short of naming alternatives or stating when-not-to-use, so no 5.

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