Kami Fall Detection

• Outcome: Review
• Latest audit: Sep 16, 2026 · 8:05 AM UTC
• Version: 1.1.2

Overview

This fall-detection skill is coherent overall, but it needs Review because it can expose sensitive camera details and use under-disclosed credentials or third-party services.

Review this carefully before installing. Only run it with camera owners' consent, avoid putting camera passwords directly inside RTSP URLs if possible, keep config.json and logs private, and disable saved clips if you do not need them. Be aware that alarm clips are sent to the KamiClaw cloud API, configured notifications send fall-event details to Feishu/Telegram/Discord, and the current Feishu fallback can upload an image to sm.ms. Do not rely on the installer to preserve an existing conda environment named kami-fall.

Installation at different times can therefore select different direct and transitive package versions. The setup process provides no lockfile, package hashes, signature verification, or approved package-index restriction. Python packages and build backends can execute code during installation. A compromised future release, dependency account, transitive package, or selected build backend would therefore execute before the Skill starts. The package names are legitimate and no typosquatting was identified, so this is a supply-chain hardening failure rather than evidence that the listed packages are currently malicious. ### Attack Path 1. An attacker compromises a permitted package release or one of its transitive/build dependencies. 2. The compromised version still satisfies the broad `>=` constraint. 3. A user runs `setup.sh` after that version becomes available. 4. Pip resolves the compromised artifact. 5. Installation or build hooks execute attacke ...[truncated 367 chars]

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

If the implementation primarily reads Telegram credentials, formats messages, and sends alerts without clear RTSP handling or KamiClaw API use, then the skill's declared purpose is misleading and the real behavior centers on external messaging. In the context of a surveillance-oriented skill that handles RTSP URLs and API keys, hidden messaging-centric behavior raises the risk of data leakage and unauthorized outbound communication.

Missing User Warnings

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

The code silently uploads local image data to a third-party anonymous image host without warning the user. Because this skill is for fall detection, the media likely contains sensitive surveillance imagery of vulnerable individuals, making undisclosed external transmission especially harmful.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

Uploading posture images from a fall-detection system to a public anonymous image host is unjustified and dangerous. The skill handles potentially highly sensitive elder-care imagery, so external publication to a public URL can expose private health-related events, home interiors, and personally identifiable information.

Content

Credential Access

High

• Category: Privilege Escalation
• Confidence: 70% confidence

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 93% confidence

Finding

The script prints guidance telling users to run 'curl https://pyenv.run | bash', which is a classic unsafe pattern because it fetches and immediately executes remote code without verification. Even though the setup script does not execute the command itself, embedding this installation advice in the skill materially increases the chance that users will run untrusted network-delivered code during setup.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The manifest and top-level README description present the skill as a cloud fall detector with optional Feishu alarm notifications. However, the README later documents Telegram and Discord notification channels and even optional two-way communication/gateway use, which materially broadens the skill beyond the stated notification scope.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The README documents saving alarm clips and structured logs containing monitoring events without warning that these artifacts may contain sensitive surveillance data. In an elderly-care setting, local retention of clips, timestamps, camera names, and event details can materially increase privacy risk if the host is shared, backed up, or later compromised.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The README states that RTSP-derived clips are uploaded to a cloud API for analysis but does not clearly warn users that potentially sensitive in-home video is transmitted off-device. In the context of elderly-care monitoring, this omission is significant because users may not appreciate the privacy, consent, and compliance implications of sending footage to a third party.

Content

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 87% confidence

Finding

The README encourages supplying API keys via config files, CLI arguments, and environment variables, and even shows realistic secret formats. CLI arguments can be exposed via process listings and shell history, and config files are often accidentally committed or shared, making credential leakage more likely.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The documentation introduces optional Telegram/Discord two-way communication features that are not necessary for one-way fall-alert delivery. Unneeded interactive channels expand the skill's trust boundary, create additional credential exposure, and may permit remote command/control paths if corresponding gateway services are enabled.

Content

No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 95% confidence

Finding

The skill declares capabilities that include environment access, file read/write, network access, and shell execution, but provides no explicit tool-scope or permissions declaration. That makes it harder for a host agent or reviewer to constrain execution, increasing the risk of over-privileged operation against local files, secrets, and external services.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

Broad triggers like 'home assistant' and 'smart home' are likely to match ordinary conversation and invoke the skill unexpectedly. Because this skill can collect RTSP URLs, write config files, and initiate continuous monitoring with networked notifications, accidental activation could lead to unintended handling of sensitive camera and credential data.

Content

No source excerpt is available for this finding.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% confidence

Finding

The setup flow directs the agent to write configuration, optionally run a command, and run the skill, while also discouraging manual review by telling the user never to edit config.json. This is risky because it encourages autonomous execution of a networked, file-writing, continuous-monitoring skill that handles secrets and camera endpoints without an explicit user confirmation checkpoint.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

The skill manifest describes detecting falls from RTSP streams via the KamiClaw cloud API, but this file adds a separate outbound integration layer to Discord, including webhooks, bot API messaging, test messaging, and media attachment support. While notifications may be related operationally, Discord alerting is a distinct capability not reflected in the manifest description, which frames the skill as cloud fall detection rather than external messaging integration.

Content

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 80% confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

                timeout=10

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

This code transmits fall-event data to Discord, a third-party service, without any built-in disclosure, consent check, or privacy guardrails. In this skill context, alerts may contain sensitive monitoring information about vulnerable individuals, making undisclosed external sharing materially risky.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

This path uploads a local posture image file to Discord without explicit warning or consent controls. In a fall-detection skill, images can expose highly sensitive in-home scenes and health-related information, so silent transmission to an external platform significantly increases privacy impact.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The file explicitly introduces 'Discord Bot API Support (Two-Way Communication)' and stores bot credentials to send messages via channel APIs. For a skill whose stated purpose is cloud fall detection, webhook-based alert delivery is easier to justify, but adding bot-token-based API access and describing it as two-way communication expands into interactive chat integration that the manifest does not claim.

Missing User Warnings

Medium

• Category: Not specified by scanner

Finding

The Bot API notification flow sends alarm details to Discord channels without any explicit privacy notice or consent mechanism. Because the data concerns fall detection and home monitoring, unintended sharing to a channel can expose sensitive personal and situational information.
