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

With no annotations, the description carries the full burden of disclosing side effects. It mentions creating a backup and replacing the source file, which are key behavioral details. However, it does not elaborate on permanence, reversibility, or any validation behavior, so it is present but not rich.

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 concise with two sentences that each add value: the first states the action, the second describes the mechanism. It is appropriately sized for the limited content, though it could be expanded with more detail without becoming verbose.

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 the tool's complexity (nested input schema, backup process, source file replacement) and the presence of an output schema, the description is incomplete. It does not explain success/failure behavior, backup location, or what 'approved' entails, leaving significant context missing.

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 description coverage is 0% for the top-level parameter, and the description does not compensate by explaining any parameters. The nested schema fields have some descriptions, but the description itself adds no meaning to the 'request' parameter or its contents. This is a significant gap.

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 tool's function: 'Apply an approved IOC plan' and describes its primary action of creating a backup and replacing the source file. This provides a specific verb and resource, though it does not explicitly distinguish itself from sibling tools like cubemx_plan_ioc_changes or cubemx_validate_ioc.

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 indicates the tool should be used to apply an approved plan, implying it follows the planning step. It provides clear context for when to use it (with an approved plan) but does not explicitly state when not to use it or mention alternatives, fitting the 'clear context, no exclusions' level.

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