analyze_library

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

With no annotations, the description must carry the full burden of behavioral disclosure. It adds the permission requirement ('Requires ADMIN') but does not disclose potential side effects, duration, or what 'analyze' entails. This is minimal behavioral transparency.

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 sentence with no filler, front-loading the core action. The imperative fragment 'Requires ADMIN' is efficient. However, it is arguably under-specified, but that is a completeness issue, not a conciseness one.

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 existence of an output schema, return values are already documented. However, for a tool that likely triggers a batch operation, the description omits important context such as whether it is synchronous, whether it modifies data, or what 'analyze' produces. The description is too sparse for the available complexity.

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 has one parameter (library_id) with no description, and schema description coverage is 0%. The description only implies that library_id identifies which library to analyze, but does not explain its format, source, or how it relates to other library tools. The description partially compensates but leaves most semantics undocumented.

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 states a specific verb ('Analyze') and resource ('all books in a library'), making it clear this tool operates on an entire library rather than an individual book or series. It distinguishes itself from sibling tools like analyze_book and analyze_series, though the exact meaning of 'analyze' remains vague.

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 guidance is provided on when to use this tool versus alternatives such as scan_library or refresh_library_metadata. The only additional information, 'Requires ADMIN', is a prerequisite, not usage guidance. There is no mention of scenarios or exclusions.

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