add_folder

Index all files in a folder into an existing project and save the pattern in config.yaml for automatic re-indexing on future runs.

Instructions

Index all files in a folder into an existing project and persist the pattern in config.yaml so the folder gets re-indexed automatically on future runs.

Args: folder_path: Absolute path to the folder to index project: Project name to add the folder to (must already exist) pattern: Glob pattern for files within the folder (default: "**/*" for all files)

Returns: Confirmation with file/chunk counts, or error message

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior4/5

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

No annotations are provided, so the description carries the burden. It discloses persistence in config.yaml, automatic re-indexing behavior, and the return value (confirmation with counts or error). It does not mention potential side effects like overwriting existing patterns, but it covers the main behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and well-structured: a clear purpose sentence, an Args block, and a Returns block. No redundant information, and each sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With three parameters, no annotations, and a clear output description, the tool is fully specified. It covers prerequisites, behavior, persistence, and return value, making it self-sufficient for an agent to decide when and how to invoke it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, but the Args section explains all three parameters: folder_path must be absolute, project must already exist, and pattern defaults to '**/*'. This adds meaning beyond the schema's type/required/default fields.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb+resource: 'Index all files in a folder into an existing project.' This clearly distinguishes from siblings like add_file (single file) and add_pattern (pattern-based indexing).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context by noting the project must already exist and that the folder pattern persists for automatic re-indexing on future runs. It lacks explicit 'when not to use' or alternative tool references, but the context is clear.

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