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

The description adds meaningful behavioral context by noting that reusing a secret name replaces the stored value for that app. This goes beyond the annotations' destructiveHint=true, clarifying what destructive action occurs, though it does not cover invalid ids or error 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 extremely concise: two sentences with no filler. It is front-loaded with the action and includes the key behavioral caveat about replacing stored values.

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 two-parameter mutation tool with strong annotations and full schema coverage, the description covers the essential behavior. It lacks return value or error handling details, but with no output schema and low complexity, this is acceptable.

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 descriptions cover 100% of parameters, so the baseline is 3. The description adds semantic context about the effect of the operation, but it does not provide additional per-parameter detail beyond what the schema already states.

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: attach submitted secret entry ids to an existing app. It is specific about the resource and operation, but it does not explicitly differentiate from sibling tools like create_secret_entry or delete_app_secrets.

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 context is implied: this tool is for binding previously submitted secrets to an app. However, it does not provide explicit when-to-use guidance, exclusions, or mention alternatives such as create_secret_entry for creating new secret entries.

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