Full Analysis
  • [PROMPT_INJECTION]: The skill implements an 'Evolution Agent' loop that ingests execution traces from quality_reports/traces/. This creates an indirect prompt injection surface where malicious content within processed traces could attempt to influence the agent's logic to propose insecure modifications to harness rules or permission boundaries.
  • Ingestion points: Reads .jsonl trace files from quality_reports/traces/ and .tsv baselines.
  • Boundary markers: The instructions do not define specific prompt delimiters for the trace content, though they emphasize evidence-based analysis.
  • Capability inventory: Can modify files in hooks/, rules/, skills/, and agents/ directories.
  • Sanitization: Relies on mandatory human-in-the-loop (HITL) review for all changes as a primary safety mechanism.- [COMMAND_EXECUTION]: The skill facilitates the modification of project source code and configuration files. It specifies a 'Promote' stage where edits are applied to hooks/, rules/, skills/, and agents/ after human approval. This is the primary intended function of the skill for harness optimization.
