Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Privilege Escalation · line 67 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
- medium Tool Misuse · line 1085 Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.Fix: Override unsafe defaults with secure settings (verify=True, auth required, restrictive permissions). Review and harden all tool configurations.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00202 | $0.11671 |
| Opus 5 | $0.00101 | $0.05836 |
| Sonnet 5 | $0.00040 | $0.02334 |
| Haiku 4.5 | $0.00020 | $0.01167 |
Grade B, and why
ros2-web-integration scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

ROS2 Web Integration Skill
When to Use This Skill
- Building a web dashboard to monitor or control a robot running ROS2
- Streaming camera feeds (MJPEG, WebRTC, compressed WebSocket) from a robot to a browser
- Exposing ROS2 services and actions as REST API endpoints
- Implementing bidirectional WebSocket communication between a web UI and ROS2 nodes
- Setting up rosbridge_suite for quick prototyping or foxglove integration
- Writing a custom FastAPI or Flask bridge to ROS2 for production deployments
- Adding authentication, rate limiting, or CORS to robot web interfaces
- Running an async web server (uvicorn) alongside the rclpy executor without deadlocks
- Publishing teleop commands from a browser joystick to cmd_vel
- Serving ROS2 parameter configuration pages or diagnostic dashboards over HTTP
Architecture Overview
Comparison Table
| Feature | rosbridge_suite | Custom FastAPI Bridge | Custom Flask Bridge |
|---|---|---|---|
| Latency | ~5-15ms (WebSocket) | ~2-5ms (WebSocket), ~10-30ms (REST) | ~10-50ms (REST only without extensions) |
| Throughput | Medium (JSON serialization overhead) | High (binary WebSocket, async) | Low-Medium (sync, GIL-bound) |
| Auth | Basic (rosauth, limited) | Full (JWT, OAuth2, API keys) | Full (Flask-Login, JWT) |
| Complexity | Low (launch and connect) | Medium (must manage two event loops) | Medium (must manage threading) |
| Video Streaming | Requires separate web_video_server | Native (MJPEG, WebSocket binary) | MJPEG via generator responses |
| Production Ready | No (exposes full topic graph) | Yes | Yes (with gunicorn) |
| When to Use | Prototyping, foxglove, quick demos | Production APIs, high-perf streaming | Simple internal tools, legacy systems |
When to Use rosbridge vs Custom Bridge
Use rosbridge_suite when:
- You need a working bridge in under 10 minutes
- The client is foxglove, webviz, or another rosbridge-aware tool
- Security is not a concern (local network, demo environment)
- You do not need custom business logic between web and ROS2
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 1,431 lines · 202 tokens per session scan B e99ab0534cfb
ros2-web-integration is a skill published in the GitHub repository arpitg1304/robotics-agent-skills (356 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 202 tokens to every session and 11,671 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
