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

The readOnlyHint annotation already declares the tool as a safe read operation, and the description redundantly repeats 'Read-only.' It adds useful scope detail by naming dependency alerts and fixed-version availability, but does not disclose permissions, rate limits, pagination, or other operational 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 main sentence is front-loaded and efficient, clearly stating the resource and what the findings include. The final 'Read-only.' sentence is redundant with the readOnlyHint annotation, so it does not fully earn its place.

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 read-only tool with one required parameter and no output schema, the description adequately covers what is retrieved, including dependency alerts and fixed-version status. It could be more complete about the return structure or pagination, but it is sufficient for correct invocation.

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 coverage is 100% for the single application_id parameter, so the schema already defines it adequately. The description adds no parameter-specific meaning beyond the schema, which is the expected baseline when schema coverage is high.

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 names a specific verb (Read), resource (source-code security findings for an Application's repository), and scope (dependency alerts and fixed-version availability). This distinguishes it from sibling tools like get_application_container_security or list_security_findings, which cover different security surfaces.

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 states what is returned but gives no explicit when-to-use, when-not-to-use, or alternative-tool guidance. It does not explain when an agent should call this instead of get_application_container_security, get_security_finding, or list_security_findings.

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