experiment

experiment is a skill for Claude Code, Codex from hdu-ailab/EasyResearch. It costs 171 tokens per session (4,713 once invoked), scanned A, original, MIT.

A workspace and process for running reproducible machine-learning and AI experiments for research papers. It organises baselines, datasets, controlled trials, multiple random seeds, ablation studies, and recorded results.

In plain words
What is it for?
Use it to build and compare baselines, test model changes, run local or remote experiments, evaluate datasets, perform ablations, and promote verified results.
Why use it?
It helps prevent unreliable comparisons caused by changing too many things at once or failing to record how a result was produced. It also keeps experiment files in a defined workspace structure.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

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

experiment 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 12d 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.

Experiment Workspace

Purpose

Use this skill to constrain research experiment workspaces and enforce a paper-driven experimental process. The goal is to find a model that is either clearly stronger than baselines or more innovative while remaining experimentally defensible.

Most practical model innovations are not invented from nothing. They are discovered by reading papers, identifying what each component is useful for, systematically recombining components from different papers, and validating which combinations actually work.

Do not jump directly to a proposed model. Read papers first, build baselines first, then try component combinations.

In the bundled paper workflow, select exactly one root from the dispatch before editing: exact-cwd experiments/ for local execution or the Research Assistant-created and marker-verified exact-cwd experiment_ssh/ mount for SSH execution. Do not mix or mirror the two roots.

Required Directory Layout

Create or maintain this structure under the user-specified experiment root:

<experiment-root>/
  .venv/
  src/
  external/
    baselines/
      <baseline_name>/
        repo/
        .venv/
    benchmarks/
      <benchmark_name>/
        repo/
        .venv/
  outputs/
  results/
  logs/
  datasets/
  experiment-record.md

For local mode, <experiment-root> is experiments/. For SSH mode, it is only experiment_ssh/, which is the local view of the configured remote project root. An explicitly supplied existing user layout may replace the local-mode root, but it never replaces the verified bundled SSH mount.

Directory rules:

  • .venv/: main experiment environment managed by uv; use it only for this project's own experiment code, routers, models, analysis, plotting, and lightweight adapters.
  • src/: source code written for this project, including data loading, models, training, evaluation, adapters, analysis, and utilities.
  • external/: all external author repositories, official benchmark repositories, and their isolated environments. Do not place cloned third-party repos directly under src/.
  • external/baselines/<baseline_name>/repo/: checkout or symlink to the author-maintained baseline repository.
  • external/baselines/<baseline_name>/.venv/: isolated uv environment for that baseline only.
  • external/benchmarks/<benchmark_name>/repo/: checkout or symlink to the official benchmark/evaluator repository.
  • external/benchmarks/<benchmark_name>/.venv/: isolated uv environment for that benchmark only.
  • outputs/: all raw outputs from experiment scripts, including failed trials, temporary models, trial models, and formal model runs.
  • results/: clean copy of formal experiment outputs only. Use this directory later for paper writing, figures, statistical analysis, and tables.
  • logs/: command logs, runtime logs, error traces, and environment snapshots.
  • datasets/: raw or processed datasets, plus dataset manifests when useful.
  • experiment-record.md: human-readable experiment progress record. Update it after every experiment run.

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.

experiment is a skill published in the GitHub repository hdu-ailab/EasyResearch (14 stars, last pushed today), licensed MIT. It adds 171 tokens to every session and 4,713 once invoked, about $0.0007 per session on Opus 5.5. 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.
