作业批改专家，支持多份作业连续批改，自动生成班级成绩统计表

Before installing, confirm the following: (1) Why does the skill need TENCENT_SECRET_ID and TENCENT_SECRET_KEY? Ask the author which Tencent APIs are used and whether you can provide a scoped service account (minimal permissions) rather than full account keys. (2) The skill writes to /root/.openclaw/workspace and persists a MEMORY.md and uploaded student files — if you will process real student data, ensure you have consent and use a sandbox with limited access and encrypted storage. (3) The SKILL.md uses child_process.exec; this can enable command injection if inputs (filenames, URLs) are not sanitized — request code review or run it in an isolated container. (4) If you cannot review the full code, do not provide high-privilege credentials; instead create a dedicated, least-privilege Tencent account and rotate or revoke keys after testing. (5) Ask the developer for a minimal reproduction that shows explicit Tencent usage (network endpoints, SDK calls) and for documentation of data retention and deletion policies.

Type: OpenClaw Skill Name: tiantian-grader Version: 1.0.0 The skill is a homework grading assistant designed to process student assignments, manage rosters, and generate statistical reports. It implements a structured workflow including OCR simulation, manual correction of recognized text, and CSV export of grades. All file operations are restricted to a dedicated workspace directory (/root/.openclaw/workspace/teacher_tiantian), and no evidence of data exfiltration, malicious command execution, or prompt injection was found in skill.md or the handler logic.
