Update Provider Credential

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

The description adds no behavioral context beyond the annotations. It does not mention whether the update is a full replacement (all fields required) or a partial update, nor does it describe the return value or side effects. The schema's required fields hint that all values must be supplied, but the description fails to disclose this important behavior.

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 a single, concise sentence that directly states the tool's purpose. It is front-loaded and contains no redundant words. While brief, it is not padded.

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?

For a tool with 7 parameters, nested objects, and no output schema, the description is too sparse. It fails to explain the full-replacement semantic, any required preconditions, or what the response will contain. The agent would need to infer too much for a reliable update operation.

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 input schema covers 100% of the parameters with descriptions, so the baseline is 3. The description adds no extra meaning beyond 'by id', which is already captured by the credential_id parameter. No additional value is provided.

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 action ('Update'), the resource ('provider credential'), and the selection method ('by id'). This distinguishes it from sibling tools like lyzr_create_provider_credential and lyzr_delete_provider_credential.

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: when you want to modify an existing provider credential. However, it does not provide explicit when-to-use vs alternatives, nor does it mention any prerequisites or exclusions. The guidance is minimal but not misleading.

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