create_file_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. It hints at creation and loading behaviors but doesn't disclose critical details: whether it overwrites existing files, requires specific permissions, handles errors (e.g., invalid directories), or returns any output. For a tool that likely involves file system operations, this lack of transparency is a significant gap.

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 a single, efficient sentence with no wasted words. It's front-loaded with the core action ('Create or load'), though it could be more specific. The structure is straightforward, but the brevity contributes to vagueness rather than clarity.

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 complexity of file system operations and the lack of annotations and output schema, the description is incomplete. It doesn't explain what 'create' involves (e.g., scanning, JSON generation) or 'load' entails (e.g., reading from disk, validation). For a tool with two required parameters and no structured output, more behavioral and result context is needed.

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%, with clear descriptions for 'baseDirectory' and 'filename'. The description adds no additional meaning beyond the schema, such as format examples (e.g., absolute vs. relative paths) or usage context. Since the schema does the heavy lifting, the baseline score of 3 is appropriate, but no extra value is provided.

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 'Create or load a file tree configuration' states a purpose but is vague about what 'create' and 'load' entail. It mentions 'file tree configuration' but doesn't specify if this involves scanning directories, generating JSON, or both. Compared to siblings like 'list_files' or 'select_file_tree', it lacks clear differentiation in scope or operation.

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?

No guidance is provided on when to use this tool versus alternatives. With siblings like 'list_files', 'select_file_tree', and 'list_saved_trees', the description doesn't indicate if this is for initial setup, persistence, or retrieval of configurations. There's no mention of prerequisites, such as whether the base directory must exist or the filename must be unique.

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