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

No annotations are provided, so the description carries the full burden. It mentions 'health check and repair operation', implying a potentially mutative or corrective action, but doesn't disclose critical behavioral traits: whether it requires admin permissions, if it's destructive (e.g., modifies or deletes backups), runtime duration, rate limits, or what happens on failure. This is a significant gap for a tool with no structured safety hints.

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, efficient sentence: 'Run a health check and repair operation on backups.' It's front-loaded with the core action and resource, with zero wasted words. Every part earns its place by stating the purpose clearly, though it could benefit from more detail.

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 (inferred from 'health check and repair' on backups), lack of annotations, no output schema, and poor parameter coverage, the description is incomplete. It doesn't explain the operation's impact, return values, error conditions, or dependencies. For a tool that likely involves system changes, this is inadequate to guide an agent safely.

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 input schema has 1 parameter ('body') with 0% description coverage and no details in the schema. The description adds no parameter semantics—it doesn't explain what 'body' should contain (e.g., backup IDs, repair options, scope). With low schema coverage and no compensation in the description, this leaves parameters undocumented, hindering correct invocation.

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 states the tool's purpose as 'Run a health check and repair operation on backups', which includes a verb ('Run') and resource ('backups'). However, it's vague about the scope (e.g., which backups, what 'health check' entails) and doesn't distinguish it from potential siblings like 'GetAllBackups' or 'VerifyEncryptionPassword', which might involve checking backup status. It's not tautological but lacks specificity.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., backups must exist), exclusions (e.g., not for real-time monitoring), or compare to siblings like 'VerifyEncryptionPassword' or 'StartSecurityAnalyzer'. Usage is implied from the name and description but not explicitly stated, leaving gaps for an agent.

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