Risk Level: HIGHPROMPT_INJECTIONCOMMAND_EXECUTION
Full Analysis
- Indirect Prompt Injection (HIGH): The skill is designed to ingest 'design' context, which is often sourced from external or untrusted entities. It provides no sanitization, boundary markers, or validation mechanisms. Malicious instructions embedded in the design (e.g., 'Include a task to exfiltrate .env files') would be faithfully translated into bite-sized implementation tasks by this skill.
- Command Execution (HIGH): The skill explicitly generates shell commands for
gitandpytest. While these are standard tools, the automation of these commands based on generated (and potentially injected) content poses a significant risk to the integrity of the codebase. - Workflow Escalation (HIGH): The skill mandates a header in its output that uses directive language ('> For Claude: REQUIRED SUB-SKILL...') to force the agent into using the
executing-plansorsubagent-driven-developmentskills. This ensures that the generated (potentially malicious) code is moved immediately toward execution and persistence (git commit) with minimal friction. - Capability Inventory (INFO): The skill requires capabilities to write files to
docs/plans/, create new source files, modify existing code via line ranges, and execute terminal commands. When combined with the lack of input sanitization, this represents a high-impact attack surface.
