Description
Point-in-time Buffett-style company analysis for stocks, Berkshire case studies, and BUY/PASS verdicts. Use when the user wants a Buffett/Graham underwriting...
Usage Guidance
This package appears to be a coherent Buffett-style research framework, but before installing or running it, do the following simple checks: 1) Inspect oracle.py (and any small scripts) for network calls, hardcoded endpoints, calls to subprocess/shell, or code that reads arbitrary filesystem paths. Search for 'requests', 'urllib', 'socket', 'subprocess', 'open(', and 'os.system'. 2) Open agents/openai.yaml and CLAUDE.md to verify they don't contain API keys or telemetry endpoints. 3) If you will allow the agent to fetch filings, be aware that this implies outbound network access — confirm which endpoints will be used and whether your environment policy allows that. 4) If you intend to let the skill update the repo, run it in a sandbox or give limited filesystem permissions (or require manual review of any saved changes). 5) The docs include absolute local paths (e.g., /Users/pineapple/...), which are benign artifacts but indicate developer-local references; they should not be trusted as runtime instructions to read other hosts. If you are not comfortable inspecting the code yourself, ask the publisher for: (a) a brief code summary of oracle.py's external I/O, (b) whether any telemetry/analytics endpoints are contacted, and (c) an explicit list of network hosts the tool may access. If any of the above reveal unexpected endpoints, credential prompts, or aggressive shell execution, treat the package as suspicious and do not run it on sensitive hosts.
Capability Analysis
Type: OpenClaw Skill
Name: think-like-warren-buffett
Version: 1.0.0
The Buffett Oracle skill bundle is a comprehensive financial research framework designed to analyze stocks using Warren Buffett's investment principles. The bundle includes a Python utility (oracle.py) for repository management, site generation, and data validation, alongside structured markdown instructions (SKILL.md, CLAUDE.md) and a large dataset of company analysis cards. The code logic and agent instructions are entirely consistent with the stated purpose; there is no evidence of data exfiltration, malicious execution, or deceptive prompt injection. The Python script's use of local file operations and a local development server is standard for this type of research tool.

Capability Assessment
Purpose & Capability
The repo, SKILL.md, and many markdown artifacts all describe a Buffett/Graham underwriting framework and cached company cards — and the included oracle.py + company_cards/ make that plausible. Minor mismatches: README and CLAUDE.md reference Claude Code and EDGAR web access while agents/openai.yaml also exists (two different runtimes hinted). SKILL.md declares no required env vars, yet the program expects to fetch filings from the web and to read/write local company_cards — network and filesystem access are implied but not declared as required environment items.
Instruction Scope
SKILL.md tightly scopes runtime behavior to reading bundled files, reusing cached company_cards, running the seven hard gates, and optionally saving cards/memos back to the repo. Those steps are coherent for the stated purpose. However the workflow explicitly instructs the agent/user to fetch SEC EDGAR filings when a card is absent and to write files when updating the repo; that implies network access and file-write operations. Also some docs (buffett_brain.md) include absolute local host paths (/Users/pineapple/...) which are incidental but unusual and should not be consulted on the host.
Install Mechanism
No install spec is provided (instruction-only packaging with an included python helper), so nothing is automatically downloaded or executed by an install step. That is lower risk than remote-download installers. Still, the included oracle.py is executable code bundled with the skill and could be run by the agent or user — review it before executing.
Credentials
The skill declares no required environment variables or credentials, which aligns with the repo's stated offline, point-in-time analysis philosophy. The repo nevertheless expects outbound web access to fetch public filings in some flows; the lack of credential requests is proportionate to the described functionality.
Persistence & Privilege
Flags show always:false and no automatic persistence. The SKILL.md instructs that if the repo is being updated the agent should save cards and append memos — that grants file write capability only if the agent/user runs these update steps. This behavior is plausible and scoped to the skill's purpose, but you should limit write permissions if you don't want the skill to modify files.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install think-like-warren-buffett - After installation, invoke the skill by name or use
/think-like-warren-buffett - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.0
别再看一堆情绪流研报了。Buffett Oracle 做的是更狠也更干净的事: 先判断这到底是投资、投机,还是 TOO HARD,再用 Buffett + Graham 框架把公司一层层拆开。过不了硬门槛,直接 PASS;真有护城河,才继续往下看。
Stop drowning in hype, hot takes, and “maybe” calls. Buffett Oracle starts by asking the question most investors skip: is this actually an investment, a speculation, or just TOO HARD? Then it runs a strict Buffett + Graham workflow that filters weak businesses fast and only goes deeper when the company earns it.
它不是只会讲故事。它会检查 7 个 hard gates,做护城河判断,要求安全边际写成数字,还会强制拿两个同业对照组出来打擂台。最重要的是,它遵守 point-in-time discipline: 只用当时公开的信息做结论,不拿后来的结果倒推装聪明。
This is not “story stock” analysis. It runs 7 hard gates, pressure-tests the moat, forces the margin of safety into numbers, and compares the company against two same-era controls. Most importantly, it follows strict point-in-time discipline: the verdict must be based only on what was public at the time, not hindsight cosplay.
如果你想要的不是“哪只票会飞”,而是一套能长期复用、能解释、能审计、还能让 AI 少胡扯的研究系统,这就是那个包。少一点 hopium,多一点 underwriting。
If you want less “what moon next?” and more durable, reusable, auditable research logic, this is the package. Less hopium, more underwriting.
