lnk

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

With no annotations, the description carries the full behavioral burden. It usefully enumerates what gets extracted (target path, volume serial, machine id, target times), implying a read-only parse, but it never explicitly states read-only behavior, error handling, or required permissions.

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 tight sentence with the key resource and output fields front-loaded; no filler. The trailing field list is slightly terse but every clause 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?

No output schema and no annotations, so the description's list of extracted fields is genuinely useful return-value context. However, with four fully undocumented parameters and no usage guidance, it is not complete enough for the agent to invoke the tool confidently.

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% across four parameters (ref, part, image, local_path), and the description explains none of them. It adds domain context about the tool overall but zero per-parameter meaning, leaving the agent unable to know how to supply input.

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 gives a specific verb ('Parse') and resource ('Windows shortcut (.lnk / Jump List entry)') and even enumerates the extracted fields. There is no lnk-specific sibling to differentiate from, so sibling routing is not required.

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 states what the tool does but never says when to reach for it, what input form is expected, or what alternatives exist among the many forensic siblings (file_info, stat, timeline). No usage context is provided.

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