Clear Garmin Credentials

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

Annotations already say destructiveHint=true, but description adds specifics: deletes encrypted credentials and OAuth tokens, ends session, and clarifies extension-settings credentials are excluded. No contradiction.

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, covering purpose, effect, and an important exception. Concise and well-structured.

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?

Given zero parameters, no output schema, and annotations indicating destructiveness, the description fully explains the action and its scope. It also distinguishes from extension-settings credentials.

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?

No parameters. Baseline of 4 applies since no params to document.

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?

Clearly states the action: delete encrypted credentials and OAuth tokens from secure storage, and end the session. Distinct from sibling tools like setup_credentials and check_credentials.

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?

Explicitly says it deletes credentials and ends the session, and clarifies that credentials from extension settings are not affected and must be cleared elsewhere. It distinguishes from setup/check credentials implicitly via the delete action, but doesn't explicitly say when to use it versus alternatives.

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