Selected work 精選作品

CloudSheriff

2026

A read-only CIS drift monitor for AWS, built for the Daytona HackSprint. It takes a Prowler baseline, diffs resource snapshots, uses CloudTrail to find who changed what, and explains every regression with an LLM. Tested against a deliberately misconfigured AWS lab.

為 Daytona HackSprint 打造的唯讀 AWS CIS 漂移監控:Prowler 基準掃描、資源快照比對、用 CloudTrail 找出誰改了什麼,每個退步都由 LLM 說明原因。在刻意設錯的 AWS 靶場上實測過。

Hermes

2026

A multi-agent security review assistant in Slack. One security lead routes each request to specialist reviewers (AWS, SaaS, PCI on Snowflake, AppSec, vendor risk, audit evidence, architecture) and returns a single report.

Slack 裡的資安 multi-agent 審查助手:由一個 security lead 把請求分派給 AWS、SaaS、Snowflake PCI、AppSec、供應商風險、稽核證據、架構等專家 reviewer,最後彙整成一份報告。

Guardrails for AI coding agents

2026

Verification gates before every commit, hooks that catch deleted tests and weakened assertions, an allowlisted DevOps MCP server, and a blameless post-mortem of a real file-deletion incident.

AI coding agent 的護欄:每次 commit 前的驗證關卡、抓出被刪測試與被弱化 assertion 的 hook、只開白名單動作的 DevOps MCP server,以及一次真實刪檔事故的無究責檢討。
