backup_configs

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

Annotations already indicate idempotent, non-destructive behavior (destructiveHint=false). The description adds that it writes to local disk and filters by inventory attributes, which is valuable context. Yet it does not clarify overwrite behavior, file naming, or whether authentication/network access is needed, so the disclosure is adequate 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 extremely concise, with a front-loaded one-line purpose followed by a compact parameter list and return note. Every sentence earns its place, and there is no fluff or repetition of schema details beyond what is necessary for clarity.

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 output schema, annotations, and full parameter descriptions, the tool is well-specified for a straightforward backup operation. However, it does not explain how multiple filters combine (e.g., AND vs OR) or specify whether filters are case-sensitive, which could affect invocation. Still, the essential context is present, so it is slightly above minimum viability.

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?

Input schema coverage is 100%, with each parameter already described clearly (e.g., filter_name as 'Filter by device name'). The description merely restates the parameter names and one example for filter_platform without adding new syntax, precedence, or combination semantics. Baseline 3 applies because the schema fully documents the parameters.

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 uses a specific verb ('Save') with a clear resource ('device configuration') and destination ('local disk'). It distinguishes itself from sibling tools like apply_config, which pushes configurations rather than saving them.

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 clearly implies the tool is for backing up device configurations to local disk, which signals appropriate use cases. However, it does not explicitly mention when not to use it or contrast it with alternatives like fetch_data or show_commands, so it stops short of a full 5.

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