Remove an API key

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

The description adds context beyond the annotations by specifying that removal is permanent and includes deletion of the associated Vault secret. It also labels the operation as write, destructive, and idempotent, which is consistent with the annotations and adds meaningful detail.

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 sentence plus three tag-like tokens, all front-loaded with the action and resource. It packs essential information without redundancy or unnecessary words.

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 simple deletion tool with two well-described parameters and annotations covering destructive and idempotent behavior, the description adequately conveys the scope and consequences, including the Vault secret. It does not mention potential prerequisites like project existence, but this is not critical given the simplicity.

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 schema already covers both parameters with descriptions (keyId as 'Pooled BYOK key UUID from list_byok_keys' and projectId as 'Project id'), so the description adds no additional parameter-level meaning beyond echoing 'by key id'. Baseline of 3 applies due to high schema coverage.

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 explicitly states the tool "Permanently remove one pooled BYOK credential by key id from the authenticated project, including its Vault secret." This clearly captures the action, resource, and scope, and distinguishes it from sibling tools like add_byok_key and list_byok_keys.

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 for removing a BYOK key but does not explicitly state when to use it versus alternatives or any conditions. It names no sibling tools or exclusions, so guidance is limited to the core purpose.

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