What it does
Sf Theory Building is an agent skill from franklee16/academic-research-skills. Use when building the theoretical argument of a Social Forces (SF) manuscript into a portable, general-audience contribution — whether the work is quantitative, demographic, comparative-historical, ethnographic, network, or computational. SF prizes a theoretically grounded result over a bare finding. Structures the argument; it does not run analyses.
Its SKILL.md is about 910 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
- Building the theoretical argument of a Social Forces (SF) manuscript into a portable
- General-audience contribution — whether the work is quantitative
- Comparative-historical
Example prompts
- “/sf-theory-building”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Concept — define the key constructs precisely; distinguish from neighbors and from the measures.
- Mechanism — the social process: who does what, why, under what structural conditions.
- Observable implications — what we should see if the mechanism operates (and what we should
- Scope conditions — where the argument holds and where it does not. Portability ≠ universality.
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
Sf Theory Building loads about 908 tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 380 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 380 words (~908 tokens).
“At Social Forces a result is not a contribution until it is attached to an argument a general social-science reader can carry elsewhere. SF's reputation rests on rigor and on findings that mean something theoretically. This skill turns results into…”
