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

With no annotations provided, the description carries full burden but lacks critical behavioral details. It states the tool applies configurations, implying a write/mutation operation, but doesn't disclose permissions required, whether it's idempotent, potential side effects (e.g., if it triggers immediate backups or restarts agents), rate limits, or error handling. This leaves the agent guessing about operational risks and outcomes.

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 that front-loads the core action and scope ('Apply backup policy configuration to all computers managed by the policy') with a clarifying note ('agent jobs only'). There is no wasted verbiage, making it highly concise and well-structured for quick comprehension.

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 complexity of applying policy configurations (a mutation operation with potential system-wide impact), no annotations, no output schema, and low schema coverage, the description is insufficient. It lacks details on what 'apply' entails behaviorally, expected outcomes, error conditions, or dependencies. For a tool that could affect multiple managed computers, more context is needed to ensure safe and correct usage.

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 0% description coverage, with one required parameter 'id' of type string. The description adds no parameter-specific semantics—it doesn't explain what 'id' refers to (e.g., policy ID, job ID, or computer group ID), its format, or where to obtain it. However, with only one parameter, the baseline is 4, but since the description fails to clarify this critical input, it's scored lower at 3 for minimal adequacy.

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 ('apply') and target ('backup policy configuration to all computers managed by the policy'), specifying it's for 'agent jobs only'. It distinguishes from general policy tools by focusing on agent-based application, though it doesn't explicitly differentiate from potential sibling tools like 'UpdateJob' or 'StartJob' which might handle similar configurations differently.

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 minimal guidance—it implies usage when needing to apply policy configurations to managed computers via agent jobs, but offers no explicit when-to-use criteria, prerequisites, or alternatives. For example, it doesn't clarify if this should be used after policy creation or as a bulk update, nor does it mention sibling tools like 'UpdateJob' that might handle similar tasks.

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