get_browser_tree

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 disclosing behavior. It only says 'Get a hierarchical tree', which is essentially the same as the tool name, and does not mention any side effects, permissions, or caveats (e.g., whether the browser needs to be open, if the tree is cached, or if it can fail). This is insufficient for a tool with zero annotation coverage.

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 concise and front-loaded with the action. It uses a single sentence for the purpose and a bullet-style list for the parameter values. Every part adds necessary information and nothing is redundant or fluff.

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 is simple, has a single optional parameter, and an output schema, so the description doesn't need to explain return values. It adequately covers the parameter. However, it lacks context about when to use this tool relative to related browser tools and doesn't mention any edge cases or limitations, making it only minimally 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 input schema has 0% description coverage, but the description explicitly lists all accepted values for category_type: 'all', 'instruments', 'sounds', 'drums', 'audio_effects', and 'midi_effects'. It also clarifies that the parameter filters by type. This fully compensates for the schema's lack of documentation.

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: 'Get a hierarchical tree of categories from Ableton's browser.' It uses a specific verb and resource, and the phrase 'hierarchical tree of categories' distinguishes it from similar browser tools like get_browser_items_at_path. However, it doesn't explicitly name or contrast siblings, so it doesn't fully earn a 5.

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?

There is no guidance on when to use this tool versus alternatives. The description only explains what it does and the parameter, with no mention of scenarios, prerequisites, or exclusions. No sibling tools are referenced, leaving the agent without direction for selection.

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