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.

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 | $0.00007 | $0.00031 |
| Opus 5 | $0.00003 | $0.00015 |
| Sonnet 5 | $0.00001 | $0.00006 |
| Haiku 4.5 | $0.00001 | $0.00003 |
Grade A, and why
beta scanned grade A with 0 findings 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 2d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

beta is a skill published in the GitHub repository robium-ai/robium (9 stars, last pushed 4d ago), licensed MIT. It adds 7 tokens to every session and 31 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
ros2-microros
Skill "ros2-microros" from Leehyunbin0131/claude-ros2-skills, covering micro-ros instructions (ubuntu 24.04 lts & ros 2 jazzy), 1. architecture, 2. documentation entry points, 3. key concepts & patterns and a. embedded client node setup (rclc in c).
ros2-troubleshooting
Diagnose ROS 2 Jazzy faults that reading the code cannot settle: QoS mismatch, sensor-mount and frame errors (REP 103/105), and odometry calibrated against CAD instead of the floor. Ships four runnable pass/fail checks.
gazebo-mcp
Gazebo / gz-sim worlds, models, poses (mock + live bridge). CLI gazebo-mcp + MCP stdio serve. Use when the user mentions gazebo-mcp, /gazebo-mcp, or related domain work. One-command Grok install from GitHub.
attach-end-effector
Mount an end-effector (parallel-jaw gripper, dexterous hand, suction tool, etc.) on a robot arm by attaching its MJCF to the arm's attachmentsite via MuJoCo's MjSpec API. Use when combining an arm MJCF and an end-effector MJCF into a single combined model. Handles known gotchas the underlying script doesn't: mesh…
urdf-to-mjcf
Use when bringing a URDF robot, hand, or CAD-generated model into MuJoCo MJCF and no hand-tuned upstream MJCF exists.
mjcf-to-urdf
Convert an MJCF (MuJoCo's XML format) to URDF for downstream consumers that don't speak MJCF (RViz, pinocchio, ROS-based motion planning, etc.). The conversion is lossy — constraints, position actuators, contact excludes, and keyframes are all dropped. Use this skill ONLY when a URDF-only consumer needs the kinematic…
