Änderungen seit dem letzten Backup

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

With no annotations provided, the description carries the full transparency burden. It discloses the default comparison target (latest vs. previous backup), the categories of changes reported, and the page handling (summary vs. full output). It also surfaces the optional baselinePath behavior. It does not explicitly state read-only or error behavior, but the described operation clearly implies a non-destructive comparison.

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?

Three sentences, each carrying real information: the core comparison behavior, the page output option, and the baselinePath option. No filler, no repetition, and the most essential behavior is front-loaded.

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 tool with only two optional parameters and no required inputs, the description covers the main usage context and output categories. It does not provide a precise output schema, but the summary of what is reported (new, changed, removed folders/notebooks; page counts or full pages) gives an agent enough to invoke and interpret the tool correctly.

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 100%, so the schema already fully documents both parameters. The description adds a bit of context by tying baselinePath to comparing with an older backup and includePages to full page output, but it largely repeats what the schema says. Baseline of 3 is appropriate.

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 a specific verb ('Vergleicht' – compares) and a concrete resource (the newest .ntcbak backup with the preceding one), and specifies what is reported (new, changed, removed folders and notebooks). This makes it unmistakably distinct from sibling tools like list_library or get_notebook, which deal with the live library rather than backup comparisons.

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 clear context for when the tool is appropriate: to compare backups and report changes. It also explains the default behavior and the optional baselinePath override. However, it does not explicitly mention alternatives or exclusion conditions, so it stops short of a perfect 5.

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