backup_config

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 the backup is 'timestamped' (a useful behavioral detail) but lacks critical information: whether this operation is safe to run during machine operation, if it requires specific permissions, what happens on failure, or the format/location of the backup file. For a mutation tool with zero annotation coverage, this is insufficient.

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 ('Save') and includes all essential elements (what is saved, where it goes). There is no wasted verbiage, and every word earns 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?

Given the tool's moderate complexity (a mutation operation with one optional parameter), no annotations, and no output schema, the description is minimally adequate. It covers the basic purpose but lacks behavioral context (e.g., safety, side effects) and output details. It meets the bare minimum for understanding what the tool does but not how to use it effectively.

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 schema description coverage is 100%, so the schema already documents the single optional 'description' parameter. The description doesn't add any parameter-specific details beyond what the schema provides, but with only one parameter (and zero parameters required), the baseline is high. A 4 reflects that the description doesn't detract from the well-documented schema.

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 specific action ('Save') and the resources involved ('current FluidNC settings and work offsets'), distinguishing it from siblings like 'restore_config' (which would load from a backup) and 'list_backups' (which would only list existing backups). It provides a complete picture of what the tool does.

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 offers no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., whether the machine must be in a certain state), or compare it to siblings like 'restore_config' for recovery scenarios or 'list_backups' for viewing existing backups. Usage is implied but not explicitly stated.

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