S2 零隐私老人守护者智能体

S2 零隐私老人健康哨兵。多模态跌倒监测，向医疗平台或智能家居总线发布健康预警（不包含物理执行裁定）。

Security Scan

The skill's code, instructions, and manifest are internally consistent with a local fall‑detection sentinel: it writes anonymized ADL logs to a local sandbox and optionally POSTs alerts to a configured S2 bus endpoint; it does not request unrelated credentials or perform unexplained network exfiltration.

Purpose & Capability

Name/description (fall detection, local alerts) match the files and code: the Python agent fuses simple multimodal state, writes ADL JSON logs to s2_bas_governance/elderly_care, and optionally posts alert JSON to S2_BUS_ENDPOINT. No unrelated cloud credentials, binaries, or install steps are requested.

Instruction Scope

SKILL.md and code confine runtime actions to local logging and an optional HTTP POST to S2_BUS_ENDPOINT. The skill does create and write files under s2_bas_governance/elderly_care (declared in SKILL.md permissions). Minor inconsistency: visualization JSON references an ${ELDERLY_DID} variable that is not declared as a required env var; this is a documentation/usage gap but not an evidence of malicious behavior.

Install Mechanism

No install spec or remote downloads are present; the package is instruction + source only. Risk from installation is low because nothing is pulled from arbitrary URLs or installed system‑wide.

Credentials

The only runtime env var used is S2_BUS_ENDPOINT (optional) which aligns with the described purpose. No secrets, API keys, or unrelated environment variables are required. Filesystem write permission to a purpose-named sandbox is proportional to the stated 'deep-time local logging' feature.

Persistence & Privilege

The skill writes persistent logs to its own sandbox directory and generates local agent identities, but it does not request 'always: true' or modify other skills or system-wide agent settings. Autonomous invocation is allowed by default (normal) but there is no evidence the skill abuses that capability.

Assessment

This skill appears to do what it says: local multimodal fall detection, local JSON logging, and optional broadcasts to a configured S2_BUS_ENDPOINT. Before installing: (1) confirm you are comfortable with files being created under ./s2_bas_governance/elderly_care and set appropriate filesystem permissions; (2) only set S2_BUS_ENDPOINT to a trusted local endpoint (e.g., internal message bus) — do not point it to a public URL; (3) the dashboard JSON references ${ELDERLY_DID} (not declared) — if you use the dashboard, supply/validate that variable; (4) note the custom license prohibits commercial deployment without a license; and (5) do not treat this as a medical device — ensure human-in-the-loop escalation and follow applicable regulations. If you need higher assurance, request provenance (source repository, author signing) or run the code in an isolated environment first.

S2-Elderly-Guardian: 健康哨兵智能体教范

1. 核心定位 (Sentinel Role)

你是一个纯粹的【健康感知哨兵】。执行“零隐私侵犯”原则，仅依赖毫米波与声学多模态进行 14 维空间感知。

2. 职责边界 (Decoupling Sensing from Actuation)

• 只预警，不裁定：当 S2-MSTC 模型确认发生极危跌倒时，你只需生成 CRITICAL_FALL_DETECTED 健康事件，并通过 S2_BUS_ENDPOINT 广播给上层应用（如专业医疗平台或全屋智能主机）。
• 绝对禁止越权执行：你无权指令任何物理网关或智能门锁执行“解锁”或“开门”动作。物理救援决策必须由上层 L1 数字人或外部医疗服务裁定。

3. 深时守护数据落盘

在平稳状态下，静默将步态衰减数据记录至本地沙箱 elderly_care/，供未来的医疗机构研究。
