At a glance

A skill your agent uses when an Agent needs tool detection, operator identity verification, gesture interpretation, or perception confidence checks in the ROS2 robot collaboration system.

  • An Agent needs tool detection
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Operator identity verification
  • Gesture interpretation

What it does

Perception is an agent skill from terrense/ros2-multimodal-robot-collab. Use this skill when an Agent needs tool detection, operator identity verification, gesture interpretation, or perception confidence checks in the ROS2 robot collaboration system.

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `examples/openpose_fist_pause.json` and `schema.json`).

The licence is MIT.

When your agent uses it

  • An Agent needs tool detection
  • Operator identity verification
  • Gesture interpretation
  • Perception confidence checks in the ROS2 robot collaboration system

Example prompts

  • “/perception”

What it can do on your machine

Read from SKILL.md and the folder at commit 47f7fca. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Perception loads about 292 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 93 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~292

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Perception Skill

Use perception topics and actions to ground plans in current sensor data.

APIs:

  • Tool detections: /perception/tool_detections, robot_collab_interfaces/msg/ToolDetection
  • Identity verification: /skills/verify_operator, robot_collab_interfaces/action/VerifyOperator
  • Gesture command stream: /hri/gesture_command, robot_collab_interfaces/msg/GestureCommand
  • YOLOv8 detector adapter: yolov8_tool_detector_node
  • OpenPose gesture adapter: openpose_gesture_node

Gesture mapping:

  • fist -> arm_pause
  • palm -> system_stop
  • thumb_up -> arm_start

Planner rules:

  • Require confidence above the configured threshold before sending a pick request.
  • If multiple tool candidates are present, choose the one closest to the requested station or ask HRI for clarification.
  • If identity verification fails, stop the mission and announce the rejection.
  • Treat system_stop as a safety-critical command.
