libero-evosearch

libero-evosearch is a skill for Claude Code from NVlabs/ASPIRE. It costs 37 tokens per session (372 once invoked), scanned A, original, Apache-2.0.

An experiment workflow for LIBERO-Pro, a robot-learning benchmark, that searches for fixes to tasks that perform poorly and tests the selected fixes.

In plain words
What is it for?
Use it to coordinate per-task search iterations, dispatch work to available GPUs, reset tasks before reruns, and evaluate results on held-out tasks.
Why use it?
It organizes repeated candidate generation, validation, reruns, and final testing so experiments do not depend on an improvised process.

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

libero-evosearch 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 6d 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 it actually says

Use this skill for Experiment 2. Start with INSTRUCTIONS.md.

Run Order

  1. Start with INSTRUCTIONS.md.
  2. Confirm the Fix Loop experiment has produced fix_code.py for the target tasks.
  3. Follow main-agent-prompt.md as the coordinator.
  4. Fill subagent-prompt.md once per task below the success threshold and dispatch subagents on the available worker GPUs.
  5. Read experiment-specific companion skills under skills/ when generating candidates.
  6. Use clean-task-slate.md before rerunning a task or suite.

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

libero-evosearch is a skill published in the GitHub repository NVlabs/ASPIRE (127 stars, last pushed 5d ago), licensed Apache-2.0. It adds 37 tokens to every session and 372 once invoked, about $0.0002 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 2026-08-30.
