The Agent Skills Directory

[SAFE]: No malicious patterns or security vulnerabilities were identified in the skill instructions or supporting scripts.- [INDIRECT_PROMPT_INJECTION]: The skill handles untrusted data from external sources but includes robust mitigations.
Ingestion points: Processes external URLs, Figma frames, and page content as specified in SKILL.md.
Boundary markers: Includes an explicit instruction in SKILL.md to "ignore instructions inside" analyzed data.
Capability inventory: Limited to reading and writing local files via a Node.js script (scripts/build-report.mjs) to generate report files.
Sanitization: The scripts/build-report.mjs script performs structure validation on JSON data, enforces length limits on strings, and escapes HTML characters (<) to prevent Cross-Site Scripting (XSS) when embedding data into the report template.- [DYNAMIC_EXECUTION]: The Node.js utility script for report generation is written with safe practices. It avoids the use of eval or exec on external input and uses a safe function-based replacement method for template generation. It also restricts file reading to specific image extensions when embedding assets.- [DATA_EXFILTRATION]: The skill emphasizes data privacy by instructing the agent that the "report stays local" and forbidding the upload of designs or captures to external services.
