Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill downloads a shell script ('install.sh') from 'https://raw.githubusercontent.com/Necmttn/ax/main/install.sh' and executes it using bash. The instructions include a manual review step using 'less' and require the user to confirm execution, which provides a layer of oversight for this remote code execution pattern.
- [EXTERNAL_DOWNLOADS]: The command 'npx skills add Necmttn/ax' is used to download and register additional agent skills from a remote repository into the local environment.
- [PERSISTENCE]: The skill documentation mentions the installation of a macOS LaunchAgent ('com.necmttn.ax-otlpd') for optional telemetry. LaunchAgents are a standard mechanism for ensuring processes run automatically at user login.
- [INDIRECT_PROMPT_INJECTION]: The 'ax ingest' command reads local Claude Code and Codex transcripts to build its graph. This creates an attack surface where instructions embedded in processed data could influence agent behavior.
- Ingestion points: Reads transcript files from the directory specified by 'AX_TRANSCRIPTS_DIR'.
- Boundary markers: No specific delimitation or 'ignore instructions' markers are mentioned for the ingested transcript data.
- Capability inventory: The skill can execute shell commands ('bash', 'ax', 'npx', 'curl'), write to the filesystem, and perform network operations.
- Sanitization: The skill does not describe any validation or filtering performed on the content of ingested transcripts.
Recommendations
- HIGH: Downloads and executes remote code from: https://raw.githubusercontent.com/Necmttn/ax/main/install.sh - DO NOT USE without thorough review
