disk_parse_prefetch

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

No annotations are provided, so the description carries the burden. It mentions pagination and that include_loaded_files increases output size, which are useful. However, it doesn't disclose that it's a read-only operation, expected performance, or permissions needed. The description adds some context beyond the minimal, but not exhaustive.

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 three sentences, each serving a purpose: first states the main functionality, second specifies the input scope, third mentions pagination. No wasted words, and concise.

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 absence of an output schema, the description gives a high-level view of what is extracted (execution history, run counts, times). It also mentions pagination. However, it doesn't describe the output structure or fields returned, which would be beneficial for a tool with multiple parameters. Still, it's mostly complete for a parse tool.

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 baseline is 3. The description adds the note about pagination, which relates to limit and offset parameters, but does not add new meaning beyond the schema descriptions. The description does not compensate significantly since the schema already explains the parameters well.

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 it parses Windows Prefetch files to determine execution history, run counts, and last execution times. The verb 'parse' and resource 'Prefetch files' are specific, and it distinguishes from sibling tools like disk_parse_amcache and disk_parse_mft by naming the file type.

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?

It explicitly mentions it can parse a single .pf file or an entire Prefetch directory, giving clear context on when to use the tool. However, it does not exclude alternative tools for other forensic artifacts, but the sibling list implies their specific uses.

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