What it does
Ceq Modern Did is an agent skill from franklee16/academic-research-skills. Use when a 《经济学(季刊)》 (China Economic Quarterly, CEQ) manuscript uses difference-in-differences with staggered adoption or heterogeneous treatment effects — to bring it into compliance with modern estimators (Callaway–Sant'Anna, de Chaisemartin–D'Haultfœuille, Sun–Abraham) instead of bare two-way fixed effects. Bare TWFE on staggered timing is a near-certain reject at CEQ.
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Econometrics and empirical research. The repository describes itself as: Comprehensive collection of Claude Code skills for academic research in economics, finance, and social sciences.
When your agent uses it
- A 《经济学(季刊)》 (China Economic Quarterly
- CEQ) manuscript uses difference-in-differences with staggered adoption
- Heterogeneous treatment effects — to bring it into compliance with modern estimators (Callaway–SantAnna
- De Chaisemartin–DHaultfœuille
Example prompts
- “Anna, de Chaisemartin–D”
- “/ceq-modern-did”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 诊断：Goodman-Bacon 分解，报告"坏比较"（already-treated 作对照）的权重；或 de Chaisemartin–D'Haultfœuille 负权重诊断。
- 现代估计量（至少一种，建议交叉验证两种）
- 事件研究图：用上述估计量画动态效应（见 ceq-figures），而非 TWFE 的污染系数。
- 对照报告：TWFE 与现代估计量并列，说明差异来源。
What it can do on your machine
Read from SKILL.md and the folder at commit 9a4b2db. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ceq Modern Did loads about 453 tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 92 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 92 words (~453 tokens).
