student-experiment-design

student-experiment-design is a skill for Claude Code, Codex from LiXin97/agora-lab. It costs 22 tokens per session (491 once invoked), scanned A, original, Apache-2.0.

A research planning workflow that turns a hypothesis into a specific experiment with comparisons, measurements, resources, and success criteria.

In plain words
What is it for?
Use it to define variables, select baseline methods, plan datasets and evaluation metrics, estimate compute and time, identify risks, and publish an executable experiment plan.
Why use it?
It exposes what must change, what must stay fixed, and what result would disprove the idea before implementation begins.

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

student-experiment-design 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 10d 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.

Student Experiment Design

Student-specific extensions

  • Add the exact artifact path where the plan will be published.
  • Add Reviewer-facing risks after ## Risks.
  • The plan is incomplete if it cannot tell a reviewer what outcome would falsify the idea.

Purpose

Translate a research hypothesis into a concrete, executable experiment plan.

Workflow

  1. State hypothesis: What specific claim are you testing?
  2. Define variables: Independent (what you change), dependent (what you measure), controlled (what stays fixed)
  3. Choose baselines: What are you comparing against?
  4. Design protocol: Steps to execute, datasets, evaluation metrics
  5. Resource estimation: Compute, time, data requirements
  6. Publish: Write to your canonical shared artifact directory: {artifact_dir}/{your-name}/experiment_plan_{id}.md

Output Format

# Experiment Plan: {title}

## Hypothesis
{Specific, testable claim}

## Variables
- **Independent**: What we vary (e.g., attention mechanism type)
- **Dependent**: What we measure (e.g., perplexity, latency)
- **Controlled**: What stays fixed (e.g., model size, dataset, training steps)

## Baselines
1. {Baseline method} — why it's relevant
2. ...

## Datasets
| Dataset | Size | Purpose | Source |
|---|---|---|---|

## Metrics
| Metric | Purpose | Expected Direction |
|---|---|---|

## Protocol
1. Step-by-step execution plan
2. ...

## Ablations
What variations to test:
1. ...

## Resource Estimate
- GPU hours: ...
- Storage: ...
- Expected runtime: ...

## Success Criteria
What results would support/refute the hypothesis.

## Risks
What could go wrong and mitigation strategies.

## Reviewer-facing risks
The objections a reviewer is most likely to raise and how the plan addresses them.

Rules

  • Every experiment must have at least one baseline comparison
  • Always include ablation studies to isolate the contribution
  • Fix random seeds and log all hyperparameters
  • Plan for at least 3 runs with different seeds for statistical significance

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.

student-experiment-design is a skill published in the GitHub repository LiXin97/agora-lab (49 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 491 once invoked, about $0.0001 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.
