Full Analysis
  • [Indirect Prompt Injection]: The skill is designed to ingest and analyze external solution files (.zip) and browser captures (.har). While this is the intended functionality, it creates a surface where malicious instructions embedded in the analyzed data could potentially influence the agent's reasoning.
  • Ingestion points: Browser HAR captures and Power Platform solution ZIP files (SKILL.md, Step 1).
  • Boundary markers: The skill specifies an authoritative list of sources for best practices (SKILL.md, Step 0), but does not define explicit delimiters to separate user data from instructions during the reasoning phase.
  • Capability inventory: The skill utilizes playwright-browser_navigate, playwright-browser_file_upload, and local file system writes (SKILL.md, Step 8).
  • Sanitization: Output is structured and validated against a specific JSON schema (findings.schema.json), which helps maintain integrity.
  • [External Downloads]: The skill fetches configuration data and citation guidelines from external sources.
  • Context: It retrieves best-practice guidelines from an official GitHub repository (microsoft/power-cat-skills). This is used for providing grounded citations in the generated audit reports.
  • [Command Execution]: The skill leverages browser automation tools to assist the user in reviewing findings.
  • Context: Tools like playwright-browser_navigate and playwright-browser_file_upload are used to open a viewer interface and load the results of the analysis. A hard rule is included to ensure that sensitive artifacts remain local and are not uploaded to external servers.
