pi05-libero — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited pi05-libero (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

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.
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.
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.
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.
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:).
The loop exits on whichever fires first — a commanded gripper open→close→open cycle (gripper_cycle, the per-item terminator for clean-all loops; set gripper_cycle_termination: true), a non-empty termination_prompt answered yes by the VLM (completed_by_vlm), or the max_windows backstop. These are the subgraph's success exits; the failure exit is failed (the loop raised). Whether the task actually succeeded is a checkpoint, not an exit — attach a postcondition that checks the world (e.g. the object is in the container), never an exit value like "folded".
