pvsyst_backup_component

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

With no annotations, the description carries the full burden. It usefully discloses the destination directory and that the copy is byte-identical, but says nothing about overwrite behavior for an existing backup, failure modes, permissions, or what is returned on success.

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?

A single front-loaded sentence with the '[Components]' grouping tag and the destination path, with no filler. It is terse but nothing is wasted; the gaps are completeness gaps rather than verbosity.

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 write tool with zero annotations, no output schema, and two fully undocumented parameters, this is under-specified. The agent cannot tell what values to supply for component_type or how the backup relates to the existing archive/restore family.

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 description coverage is 0% for both parameters. 'filename' is ambiguous — is it the source file to back up or the destination name? — and 'component_type' gives no hint of its allowed values or how it constrains the lookup. The description adds no parameter meaning to compensate.

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 ('save a byte-identical backup') plus the destination path, which is more precise than a bare 'backup'. It is distinguishable from archive/restore siblings by the 'byte-identical' qualifier, though it never explicitly contrasts with pvsyst_archive_component.

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?

No statement of when to use this versus archive_component, copy_component, or restore_archived_component, and no prerequisites such as the component needing to exist. The agent is left to infer the trigger condition from the name alone.

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