chromium_parse_cache_tool

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'Parse' which implies a read operation, but it does not mention whether the tool modifies anything, performance implications, limitations (e.g., only HTTP cache, not other cache types), or any required access permissions to the profile. No extra behavioral context is provided.

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 two sentences and directly to the point. The inclusion of a typical profile path is useful and earns its place. There is no redundancy or filler.

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 tool has six parameters and an output schema, this description is quite sparse. It fails to explain what a 'cache record' contains, how the output is structured, or any caveats (e.g., cross-platform path differences, locked file issues). The sibling set includes many similar parse tools, but the description does not clarify how this one differs in context.

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 already covers all six parameters with descriptions (100% coverage), so the baseline is 3. The description adds a typical Windows profile path example, which is helpful but only marginally extends the schema's formal definition of 'profile_path'. It does not provide deeper semantics for other parameters like 'decompress' or 'include_body'.

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 the action ('Parse') and the specific resource ('Chromium HTTP cache records'), which immediately distinguishes it from sibling tools that parse other data types like history, cookies, or downloads. It also provides a concrete profile path example, reinforcing the tool's focus.

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 includes a typical profile path, which is a practical usage hint. However, it does not explicitly state when to use this tool versus alternatives (e.g., Firefox cache parser) or any exclusions. The usage context is implied by the tool name rather than explicitly articulated.

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