digital-forensics
Authorized digital forensics: memory dumps, disk timelines, PCAP investigation, artifact triage, and incident-response evidence preservation.
Digital Forensics & IR Artifacts
When to Use
- Investigating a suspected incident with forensic rigor.
- Building defensible timelines from disk/memory/network artifacts.
适用场景
- 内存转储分析(Volatility 2/3)
- 磁盘/ E01 / 落地文件时间线
- PCAP 溯源与协议还原(可联合
protocol-reverse/) - 主机伪影:Prefetch、Shimcache、Event Log、浏览器历史
- 应急响应 IOC 提炼(联合
malware-analysis//threat-hunting/)
工作流
1. 保全
□ 计算 SHA256;记录时区与采集命令
□ 工作在副本上;原始只读
□ chain of custody 备注写入 timeline
2. 内存
vol -f mem.dmp windows.info
vol -f mem.dmp windows.pslist
vol -f mem.dmp windows.netscan
vol -f mem.dmp windows.cmdline
3. 主机伪影
□ 事件日志:Security / PowerShell / Sysmon
□ 持久化:Run 键、服务、计划任务、WMI
□ 执行痕迹:Amcache、Prefetch、BAM
4. 网络
□ tshark 统计会话与 DNS
□ 导出可疑流 → protocol-reverse 或 malware C2 分析

任务完成自检
- [ ] 是否保全哈希与副本策略?
- [ ] 时间线是否可复核?
- [ ] IOC 是否脱敏分级?
- [ ] Checklist?
Limitations
- Chain-of-custody requirements apply; work on verified copies, never originals.
- Encrypted or anti-f

accesslint-diff
Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [<name>] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use `scan` for a full audit with no diffing.
accesslint-scan
Audit a live page for accessibility issues, locate each WCAG violation precisely, and return a selector-grounded fix worklist without editing.
accint-commitments
Triage acc's open promises and close them with honest real-world verdicts via acc_act(runtime="outcome").
accint-frames
Drain acc's deliberation queue — open/waiting brain_frames checkpointed by headless runs — via acc_act(runtime="continue").
accint-solve
Route a goal through acc's scored-memory loop via acc_act(runtime="solve"); deliberate any returned brain_frame and submit via continue.
ad-creative
Create, iterate, and scale paid ad creative for Google Ads, Meta, LinkedIn, TikTok, and similar platforms. Use when generating headlines, descriptions, primary text, or large sets of ad variations for testing and performance optimization.
