Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.02548 |
| Opus 5 | $0.00047 | $0.01274 |
| Sonnet 5 | $0.00019 | $0.00510 |
| Haiku 4.5 | $0.00009 | $0.00255 |
Grade A, and why
openbb-data-fetcher 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 10d 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.

OpenBB Data Fetcher
Role
Use OpenBB as a standalone data access layer. Retrieve requested data, preserve provenance, normalize it into a usable structure, and make uncertainty explicit in the returned dataset package.
Default Behavior
- Use the OpenBB Python package directly with
from openbb import obb. - Do not use the OpenBB MCP server unless the user explicitly asks for MCP.
- Prefer the bundled
scripts/fetch_openbb.pyhelper for simple endpoint calls instead of ad hoc shell heredocs. - Prefer official OpenBB endpoints and provider extensions over web scraping.
- Do not substitute ordinary web search just because OpenBB is not installed; install OpenBB, retry the request, or report the installation blocker.
- Use web search as a fallback only after OpenBB installation, import, endpoint, provider, or credential setup has failed and the requested task still needs an answer.
- When using fallback web research, label it clearly as
non-OpenBB fallback dataand cite sources; do not imply it came from OpenBB. - Return structured data first: DataFrame, CSV, JSON, or a concise schema/sample when the dataset is large.
- Keep raw provider fields unless the user asks for a transformed model-ready dataset.
Quick Start
- Identify the data domain: equity, ETF, index, crypto, fixed income, options, economics, fundamentals, news, analyst estimates, calendar events, or regulatory filings.
- Identify the instrument identifiers, date range, frequency, provider preference, and required fields.
- Check whether OpenBB is installed. If it is missing, install it into the active Python environment and retry the same request.
- Use the reusable helper when a simple endpoint call is enough. Do not force
provider="yfinance"unless that endpoint supports it:
python skills/data-access/openbb-data-fetcher/scripts/fetch_openbb.py \
--install-if-missing \
--endpoint equity.price.historical \
--params '{"symbol":"AAPL","start_date":"2024-01-01","provider":"yfinance"}' \
--output /tmp/aapl_prices.csv
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

openbb-data-fetcher is a skill published in the GitHub repository monarchjuno/vibe-investing (297 stars, last pushed 4mo ago), licensed MIT. It adds 94 tokens to every session and 2,548 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
