pi05-libero

pi05-libero is a skill for Claude Code, Codex from graph-robots/open-robot-skills. It costs 183 tokens per session (1,186 once invoked), scanned A, original, Apache-2.0.

A closed-loop robot-control skill using OpenAI's π0.5 LIBERO model to perform tabletop pick-and-place with a Franka Panda robot in simulation.

In plain words
What is it for?
Use it to pick up rigid tabletop objects and optionally place or drop them into containers in LIBERO or robosuite.
Why use it?
It provides a ready-to-run policy for the specific robot, camera setup, and LIBERO task format, reducing the work needed to connect a model to the simulator.

Token cost

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.

Security

Grade A, and why

pi05-libero 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 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (server.py, tools.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

pi05-libero

Closed-loop VLA-policy skill backed by one model checkpoint: openpi's π0.5 LIBERO checkpoint (pi05_libero). The skill is the model — it owns its serving preset (pi05-libero), so a policy node names this skill, not a free-floating policy_id. The closed-loop replan/execute/terminate body and the load-bearing LIBERO observation encoding live in gap.runtime.policy.run_policy_loop; the websocket client is resolved (and cached per preset) through the executor's PolicyExecutor.

Capability

  • Embodiment: Franka Panda (LIBERO/robosuite), OSC_POSE delta action space [Δx, Δy, Δz, Δrx, Δry, Δrz, gripper]. No embodiment translation happens in the loop — the checkpoint's native action space is forwarded to sim.apply_policy_action.
  • Tasks: the LIBERO pick-and-place distribution — pick a tabletop rigid object, optionally place/drop it in a container. Works best steered: perceive the target and hover the end-effector above it (preserving the current rotation) before handing over, so the policy starts in-distribution.
  • Not for: deformables / cloth folding, articulated objects, non-LIBERO embodiments, or tasks the checkpoint never saw. If the task is outside this envelope, pick a different skill or report a missing capability — do not delegate it here and hope.

Serving

The bundle ships its own server.py (vendored from openpi scripts/serve_policy.py) and declares openpi as a git dep in its own pyproject.toml — so this bundle is self-contained: no $GAP_OPENPI_DIR clone, no shared venv. First-run setup is gap skills install pi05-libero, which uv syncs the bundle's .venv/ with all model deps. The launcher then spawns the server via uv run --project policies/pi05-libero -- python server.py ... (so the bundle's own venv activates automatically) and downloads the checkpoint from s3://openpi-assets/checkpoints/pi05_libero on first run.

Run it yourself with gap policy serve pi05-libero. A policies: config entry named pi05-libero overrides the recipe (e.g. an external url:).

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.
