What it does
Fin Core is an agent skill from AojdevStudio/Finance-Guru. Finance Guru™ Core Context Loader Auto-loads essential Finance Guru system configuration and user profile at session start. Ensures complete context availability for all financial operations.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
The repository describes itself as: Self-hosted family office engine: typed Python calculators, a private SQLite ledger, and specialist agents for Claude Code and Codex. Agents propose. Typed code computes.
Example prompts
- “/fin-core”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- System Configuration
- User Profile
- Portfolio Ledger
- System Context
What it can do on your machine
Read from SKILL.md and the folder at commit 90c235e. 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
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Fin Core loads about 1.2k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 465 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:73
model-probability values are read from `.env` (see `.env.example`): `FG_PORTFOLIO_STRUCTURE`, `FG_W2_MONTHLY_INCOME`, `
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 465 words (~1,169 tokens).
