otel-browser
OpenTelemetry browser/RUM mechanics for SPAs and MPAs. Use for “browser OTel,” “frontend observability,” “Web Vitals,” `sdk-trace-web`, `WebTracerProvider`, `browser-sdk`, browser instrumentations, page-load or route tracing, sessions, clicks, console capture, JavaScript errors, or frontend-to-backend trace correlation. Browser telemetry is privacy- and volume-sensitive, and experimental packages move quickly. Not for Node.js service instrumentation or Collector-only configuration.

2 findings: 2 critical severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Most URLs are legitimate docs, local Collector endpoints, and well-known GitHub projects, but several example/telemetry endpoints (notably https://production.example.test/test, https://production.example.test/enable-all and https://telemetry-backend.example.test) are embedded in untrusted fixtures as "run this" instructions or carry client-held credentials, which matches high-risk distribution/command patterns and makes them suspicious.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The repo includes deliberate hostile fixtures: embedded commands urging remote requests, client-held authorization headers, overly-broad cross-origin trace propagation, and unbounded capture settings that together enable token/PII exfiltration and hostile data collection.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The skill describes browser RUM instrumentation that at runtime captures and ingests outsider-authored page content and DOM text (including untrusted anchors, data-* attributes, console/error messages, and other page-provided strings) via the Browser SDK/instrumentation hooks, making the workflow exposed to indirect prompt-injection text from whatever page the user loads.
