The Agent Skills Directory

[DYNAMIC_EXECUTION]: The skill provides templates for defining custom build rules using Lua-based hooks such as on_load and before_buildcmd_file. These hooks execute logic at runtime within the Xmake build environment to configure targets and generate build commands.
[COMMAND_EXECUTION]: The custom protobuf rule example demonstrates how to invoke external command-line utilities using batchcmds:vrunv. Specifically, it shows the execution of the protoc compiler with arguments derived from project files.
[INDIRECT_PROMPT_INJECTION]: The provided rule templates ingest file paths and source content to perform transformations (e.g., utils.replace and utils.bin2c). This creates a surface where the build process reacts to project data, though no unsafe interpolation or exfiltration vectors are present.
Ingestion points: File paths provided to add_files and sourcefile variables in custom rules (SKILL.md).
Boundary markers: None explicitly shown in templates, which is standard for build configuration snippets.
Capability inventory: File system access (path.join, mkdir), external command execution (vrunv), and target metadata modification (target:add).
Sanitization: None present in the code snippets; relies on the underlying Xmake framework's handling of arguments.
