backup_config

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

With no annotations, the description carries the full burden, and it does disclose useful behavior beyond the schema: the transfer mechanism (HTTP download) and the destination (the backup dir). However, it omits permissions/auth needs, whether it overwrites existing backups, and any size/time constraints.

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?

Two tight lines with the action front-loaded and the parameter values following. The abbreviated 'content:' fragment is slightly terse but wastes no words.

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?

For a single-parameter tool with an output schema (so return values need no explanation), the description covers the action, destination, and valid input values. It stops short of documenting where the backup dir lives or auth requirements, but is otherwise sufficient.

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 coverage is 0% and the single 'content' param has no enum in the schema, so the description's list 'running|startup|backup|flash_log|buffer_log|tech_support' is the only place the allowed values appear. It compensates for the coverage gap, though it does not explain what each value captures.

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?

States a specific verb and resource: 'Download a backup over HTTP into the backup dir,' which is concrete and actionable. It does not differentiate itself from the closest siblings (sync_snapshot, sync_to_github, save_running_to_startup), which an agent might confuse with a backup operation.

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?

There is no explicit when-to-use guidance, no prerequisites, and no named alternatives among the many sibling tools. The content list hints at optional modes but reads as an enumeration rather than usage direction.

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