The Agent Skills Directory

Command Execution: The tutorial involves running buck2 build commands and shell utilities like mkdir and cat to demonstrate build processes. These are standard operations for a developer tool tutorial and are intended to be executed in a dedicated workspace.
Dynamic Execution: The skill teaches the creation of Buck2 rules that generate and execute shell and Python scripts via the ctx.actions.run API. This pattern is a core feature of the Buck2 build system for performing arbitrary build tasks.
Indirect Prompt Injection: The agent is designed to read local files such as BUCK and uppercase.bzl to track user progress. This ingestion of local workspace data is a potential consideration for processing untrusted content, though it is limited to the tutorial's files and used to facilitate the interactive teaching flow.
Ingestion points: SKILL.md (reading uppercase.bzl, BUCK, input.txt to assess state).
Boundary markers: Absent for local file reads.
Capability inventory: File system access (mkdir), file writing, and command execution via buck2.
Sanitization: None specified for file content analysis.
Vendor-Specific Configuration: The tutorial utilizes repository structures and naming conventions (e.g., fbcode//, ovr_config//) that are characteristic of the author's official development environment, representing standard usage for the tool.
