| description | Write experiment guides for handing off work from agent to human. Use when the user asks what experiments are needed, requests a task list for a student, or when todo.md contains items the agent cannot complete (code execution, data collection, figure generation, hardware access). Produce a concise guide with specific deliverables per experiment: CSV schema, plotting script, and final figure. |
LAW Call for Experiments
Write experiment guides for human execution. These guides hand off work that the agent cannot complete: running code, collecting data, producing figures, or accessing hardware.
When to use this skill
Use when todo.md contains items that the agent cannot complete. These items are marked ⏳ WAITING ON DATA in todo.md with a pointer to the experiment guide. The guide is a task list, not a narrative — the person executing it should not need to read reviews or understand the paper's narrative.
Writing rules
Rule 1: No justification
The person running experiments knows why. Tell them what to produce, not why. Remove all "because the reviewer said" or "this validates assumption X" language.
Rule 2: Three deliverables per experiment
Every experiment must specify exactly three outputs:
- CSV file — path in
data/, column names, what each column contains
- Plotting script — path in
figs/, what CSV it reads, what plot it produces
- Final figure — path in
figs/, the PNG file name
Never say "report the results" or "add a figure." Always specify exact file paths.
Rule 3: Never reference reviewers
The guide is a task list. No reviewer names, no paper state, no priority justifications based on reviewer impact. If prioritization is needed, use a simple numbered list.
Rule 4: Language matches audience
Write in the language the executor prefers. Default to Chinese — the guide targets a Chinese-speaking PhD student. If the user explicitly asks for English, or if the agent cannot determine the audience's language, write in English.
Do not assume Chinese is always correct. If the user says "my student speaks English," write in English.
Templates
Use the template that matches the language. Default to Chinese unless the user specifies otherwise.
Chinese template
# [Paper Name] 补充实验
## 实验 N: [Name]
### 数据收集
- [Step 1]
- [Step 2]
### 交付物
- **CSV:** `data/xxx.csv`
- 列：`col1, col2, col3`
- **绘图脚本:** `figs/fig-xxx.py`
- 读取 `data/xxx.csv`
- 输出：[description of plot]
- **最终图:** `figs/fig-xxx.png`
English template
# [Paper Name] — Supplementary Experiments
## Experiment N: [Name]
### Data Collection
- [Step 1]
- [Step 2]
### Deliverables
- **CSV:** `data/xxx.csv`
- Columns: `col1, col2, col3`
- **Plotting script:** `figs/fig-xxx.py`
- Reads `data/xxx.csv`
- Produces: [description of plot]
- **Final figure:** `figs/fig-xxx.png`
Integration with todo.md
After writing the guide, update todo.md:
- Items requiring experiments → mark ⏳ WAITING ON DATA
- Add pointer: "See Experiment N in expr.todo.md"
- Items completed by the human → agent verifies deliverables exist, then marks done
