The Agent Skills Directory

[COMMAND_EXECUTION]: The scripts/ast_grep_helper.py wrapper uses the subprocess module to execute the ast-grep (sg) binary for code analysis and transformation. It also executes platform-specific shell scripts (install.sh and install.ps1) to manage the tool's installation and lifecycle.
[EXTERNAL_DOWNLOADS]: The installation scripts (install.sh, install.ps1) download the ast-grep binary from GitHub's official releases when it is not found on the local system. The download targets the official repository of the project, which is a well-known service.
[SAFE]: The skill presents an indirect prompt injection surface as it ingests and processes untrusted code from the local filesystem. However, this is inherent to the tool's primary purpose as a code search and rewrite utility.
Ingestion points: scripts/ast_grep_helper.py subcommands ingest files from user-defined paths.
Boundary markers: No explicit boundary markers are used when outputting search results.
Capability inventory: The skill can read and mutate local files via the sg binary.
Sanitization: The helper script implements pattern validation to catch common regex-based syntax errors before execution.
