What it does
Jfr Heterogeneity is an agent skill from franklee16/academic-research-skills. Use when the heterogeneity analysis of a 《金融研究》 (Journal of Financial Research) manuscript is too coarse or atheoretical — to cut along finance-relevant dimensions (ownership, bank type, market segment, financing constraint, region) that the mechanism predicts, not arbitrary splits.
Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
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
- The heterogeneity analysis of a 《金融研究》 (Journal of Financial Research) manuscript is too coarse
- Atheoretical — to cut along finance-relevant dimensions (ownership
- Financing constraint
- Region) that the mechanism predicts
Example prompts
- “/jfr-heterogeneity”
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
Jfr Heterogeneity loads about 357 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 59 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 59 words (~357 tokens).
