All Implemented Interfaces:

public class ListFolderTool
extends DecisionTool<Folder, ListArtifact<FileEntry>>

Lists a folder: every regular file in it, by name, with what its bytes say it is and, for a text file, its first words. No model: the sniffing is the extract step's, the head is a few hundred bytes decoded. The list is what a decision model chooses files from, so each entry carries exactly what a person would glance at in a file browser. A path that is not a folder on this machine is refused with the reason (InvalidInputException).

Method Details

getRequirements

public JobRequirements getRequirements()

Description copied from class: AbstractTool

Default requirements for tools. Subclasses should override to add database, LLM, or other requirements. JobType is handled by AbstractTool.getJobType(), not here.

Specified by:

getRequirements in interface Job<ListArtifact<FileEntry>>

Overrides:

getRequirements in class AbstractTool<Folder, ListArtifact<FileEntry>>

Returns:

resource requirements, or null if the job needs no resources

execute

public ListArtifact<FileEntry> execute(JobResources resources,
 JobContext<ListArtifact<FileEntry>> context)
                                throws LLMReadableCheckedException

Description copied from interface: Job

Executes the job with the provided resources and context. A job reports progress and checks for cancellation through the context, and completes all its work before returning. A tool narrows this contract to the LLM-readable exceptions of Tool.execute(JobResources, JobContext).

Parameters:

resources - the allocated resources

context - the job execution context for monitoring

Returns:

the job result, which may be null

Throws:

LLMReadableCheckedException - if execution fails
