chromium_parse_bookmarks_tool

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that it 'parses' bookmarks, which implies a read-only operation, but it does not disclose whether it modifies data, requires specific permissions, handles running browser instances, or what the output looks like. This is a minimal disclosure.

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, each earning its place: the first states the core purpose, the second provides a practical profile path hint. There is no unnecessary detail or repetition.

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 4 parameters, a rich schema, and an output schema, the description is mostly complete. It provides the essential purpose and a key usage hint. However, it lacks any behavioral caveats (e.g., whether Chrome must be closed) or explicit alternative guidance, which would make it fully complete.

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 covers all 4 parameters with clear descriptions (100% coverage), so the baseline is 3. The description adds value by providing a concrete example for 'profile_path' ('C:\Users\<user>\AppData\Local\Google\Chrome\User Data\Default'), which helps the agent understand how to construct the path. Beyond that, it does not add much for other parameters, but the schema already handles them 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 identifies the action ('Parse'), the resource ('Chromium bookmark URL entries'), and the source ('from a browser profile'). This distinguishes it from sibling tools like chromium_parse_history_tool and firefox_parse_bookmarks_tool by specifying bookmarks and Chromium.

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 implies use when needing to parse Chromium bookmarks, and the typical profile path provides practical context. However, it does not explicitly state when to use this tool versus alternatives (e.g., Firefox bookmark parsing) or mention any exclusions or prerequisites beyond the profile path.

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