Parse a bookmark export file

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

With no annotations, the description carries the full burden of behavioral disclosure. It adds useful context: reads from disk, auto-detects formats, and outputs 'clean JSON.' However, it does not mention error handling, file size limits, required permissions, or the structure of the returned JSON, leaving significant behavioral aspects undisclosed.

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, front-loaded with the main action, and every sentence provides necessary information. It lists formats concisely without unnecessary detail.

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?

The tool has no output schema and no annotations, so the description should explain the return value. It only says 'clean JSON' without specifying the JSON structure (e.g., array of bookmark objects, fields included). While it covers input and auto-detection well, the lack of output format details leaves a gap for a parsing 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 coverage is 50% (only 'path' has a description; 'format' has an enum but no description). The description compensates by explaining auto-detection and listing the supported formats, which adds meaning to the 'format' parameter beyond just its enum values.

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 tool's function: parsing a bookmark export file from disk into JSON. It specifically names the resource (bookmark export file) and the action (parse), and lists the supported formats, distinguishing it from sibling tools that list, search, or export bookmarks.

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 when to use this tool (for importing/parsing bookmark exports) and clearly distinguishes it from sibling tools that operate on already-parsed bookmarks. It does not explicitly state exclusions or alternatives, but the context is clear enough for an agent to select it appropriately.

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