Risk Level: SAFEPROMPT_INJECTION
Full Analysis
  • [PROMPT_INJECTION]: The skill is designed to ingest untrusted data from the repository (source code, ADRs, and documentation) and use it to challenge user assumptions. This creates a surface for indirect prompt injection where malicious instructions embedded in the repository could influence the agent's behavior.
  • Ingestion points: The skill explicitly reads from CONTEXT.md, CONTEXT-MAP.md, docs/adr/, and repository source code to ground its interrogation (SKILL.md).
  • Boundary markers: The instructions do not define explicit delimiters or 'ignore instructions' warnings when interpolating repository content into the agent's context.
  • Capability inventory: The skill can propose modifications to documentation files like CONTEXT.md and ADRs using templates (ADR-FORMAT.md, CONTEXT-FORMAT.md). However, it requires explicit user approval for these semantic changes and limits updates to 2 files per cycle (SKILL.md). No network or shell execution capabilities were detected.
  • Sanitization: There is no evidence of sanitization or escaping of the content read from external files before it is processed by the agent.
