vibe-investing: Instructions file for Codex

AGENTS.md

vibe-investing AGENTS.md is an instructions file for Codex, OpenCode from monarchjuno/vibe-investing. It costs 319 tokens per session, scanned A, original, MIT.

Repository instructions for coding agents working on a finance and investing skills collection. They define the repository’s purpose, folder structure, naming, and editing rules.

In plain words
What is it for?
Maintaining investing skills, organizing folders, naming files, deciding where guidance belongs, and keeping updates small and focused.
Why use it?
They give agents shared rules to follow, reducing inconsistent changes and misplaced documentation. More specific instructions can override them in deeper folders.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vibe-investing AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Repository Agents Guide

This file defines maintenance rules for the whole repository.

Scope

  • Apply these rules to all files and folders unless a deeper AGENTS.md overrides them.

Repository Purpose

  • Use this repository to manage finance and investing skills.
  • Keep each skill reusable, modular, and easy to evolve over time.

Structure Rules

  • Keep user-facing project overview in the root README.md only.
  • Use AGENTS.md files for folder-level maintenance instructions.
  • Keep skill-specific operational guidance inside each skill's SKILL.md.
  • Prefer capability-first categories over asset-class-first categories when one skill should span equities, crypto, credit, commodities, or other assets.
  • Keep this repository focused on investing logic and reusable output styles rather than every possible file-conversion workflow.
  • Keep the repository aligned with the generic skill spec instead of assuming a single host product.

Naming Rules

  • Use lowercase hyphen-case for skill folder names.
  • Use category folders under skills/ to group shared capabilities.

Editing Rules

  • Prefer small, targeted updates over broad rewrites.
  • Do not add extra documentation files like nested README.md files unless explicitly requested.
  • Keep reference material inside references/ and use skill-local scripts/ only when they provide real leverage.
  • When final delivery must be docx, pdf, xlsx, or another concrete file type, prefer applying a specialized external skill directly unless repo-specific behavior is required.
  • Remove placeholder files and speculative sample skills unless they serve an immediate purpose.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
