Full Analysis
  • [PROMPT_INJECTION]: Indirect prompt injection surface identified in the handoff and checkpoint-resume patterns.
  • Ingestion points: Implementation guides (e.g., references/checkpoint-resume.md) advise reading state from .claude/chain/*.json files which may contain outputs from external tools or previous subagent phases.
  • Boundary markers: No delimiters or 'ignore embedded instructions' warnings are present in the provided patterns.
  • Capability inventory: The patterns utilize powerful tools including CronCreate (scheduled command execution), Agent (subagent spawning), and Write (file system access).
  • Sanitization: No sanitization or validation of the ingested JSON data is described before interpolation into subsequent prompts.
  • [COMMAND_EXECUTION]: The skill promotes the use of CronCreate to schedule tasks that execute system commands.
  • Evidence: references/cron-monitoring.md and SKILL.md (Pattern 5) demonstrate scheduling recurring checks using CLI tools such as gh (GitHub CLI) and npm test. This functions as a persistence mechanism that survives the current session, allowing for scheduled command execution.
