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: 4 findings, up to medium
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 | $0.00048 | $0.00684 |
| Opus 5.5 | $0.00019 | $0.00274 |
| Sonnet 5.5 | $0.00010 | $0.00137 |
| Haiku 4.5 | $0.00005 | $0.00068 |
Grade A, and why
you-finance 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 23d 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.
How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You.com Finance Research
Use this skill to answer finance-specific questions through the You.com you-finance MCP tool.
Prerequisites
The You.com finance MCP endpoint must be reachable from the host:
- Server URL:
https://api.you.com/mcp/finance - Auth: OAuth login into the server (preferred),
YDC_API_KEYbearer auth, or an MPP/x402-aware MCP client. For bearer auth, configure the host MCP client to send the key from the standardYDC_API_KEYenvironment variable as a Bearer token. - Required tool:
you-finance
Workflow
- Call the
you-financeMCP tool with the finance question. It covers company financials, SEC filings, earnings, guidance, analyst context, and valuation comparisons. you-financesupports You.com auth viaYDC_API_KEYbearer auth, OAuth, or MCP payment-header pass-through. If the MCP client receives a402 payment-requiredchallenge, let the client pay externally and retry with payment headers. Do not handle wallets or signing in this skill.- For keyless payment with no API key and no manual signing, compose the You.com MCP server with the Coinbase Payments MCP server; see Coinbase Payments MCP path for setup.
- If the
you-financetool is unavailable, tell the user what is missing, provide the setup options from the prerequisites above, and request approval before installing, connecting, or changing configuration.
When to use
- Stock price or ticker lookup.
- Company financials, filings, earnings, guidance, analyst context, or valuation comparisons.
- Market, sector, ETF, macro, rates, commodities, or crypto questions where finance-specific sources are expected.
When not to use
- General web search: use
you-webandyou-search. - Reading arbitrary URLs: use
you-webandyou-contents. - Non-financial deep research: use
you-research. - Quick non-research finance lookups where
you-weboryou-searchis sufficient.
Answering rules
- Include the date or timeframe for market-sensitive data.
- Cite URLs or source names returned by the tool for factual claims.
- Flag uncertainty when sources disagree or when data may be delayed.
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.

you-finance is a skill published in the GitHub repository youdotcom-oss/agent-skills (94 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 684 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
