What it does
Stock Snapshot is an agent skill from mohitagw15856/pm-claude-skills. Fetch a stock quote snapshot with keyless curl — Yahoo Finance's public chart endpoint, read with the discipline unofficial market data demands: timestamped, delayed-flagged, and never advice. Use when asked what's this stock at, how did the market do today, get me a ticker's recent range, or pull basic price history. Produces the quote with change and range context, the source-honesty caveats (unofficial, possibly delayed), the rerunnable command, and a hard no-advice line.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Business, Finance & HR, covering Stock and market analysis. It works with yfinance. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked whats this stock at
- How did the market do today
- Get me a tickers recent range
- Pull basic price history
Example prompts
- “s this stock at, how did the market do today, get me a ticker”
- “/stock-snapshot”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
query1.finance.yahoo.com
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
Stock Snapshot loads about 1.2k tokens when it runs. Until then it costs about 124 tokens; SKILL.md has 591 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 passed
The automated check found no risky patterns in SKILL.md.
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.

- description
- Fetch a stock quote snapshot with keyless curl — Yahoo Finance's public chart endpoint, read with the discipline unofficial market data demands: timestamped, delayed-flagged, and never advice. Use when asked what's this stock at, how did the market do today, get me a ticker's recent range, or pull basic price history. Produces the quote with change and range context, the source-honesty caveats (unofficial, possibly delayed), the rerunnable command, and a hard no-advice line.
Stock Snapshot Skill
Stock prices are the live-data request with the highest stakes-to-availability mismatch: everyone asks, keyless official sources barely exist, and the standard keyless answer — Yahoo Finance's public chart endpoint — is unofficial, reshapeable, and possibly delayed. This skill uses it the only defensible way: clearly sourced, timestamped, delay-flagged, wrapped in the no-advice line, and honest that anything portfolio-grade belongs with a real brokerage feed. Within those fences, it's genuinely useful: quotes, day moves, and recent ranges in one curl.
What This Skill Produces
- The snapshot — last price, day change, day range, volume — with its timestamp and delay flag
- Context on request — 52-week position, recent trend from the chart series (described, not extrapolated)
- The command — exact curl, rerunnable
- The fences — unofficial-source note and the no-advice line, every single time
Required Inputs
Ask for these if not provided:
- The ticker — resolved carefully: company names map to multiple listings ("did you mean the NYSE or Frankfurt listing?"); exchange suffixes matter (
SAP.DEvsSAP) and the wrong-listing answer is confidently wrong in the wrong currency - What they actually want — a number, a day summary, or a range/history — shapes which fields get read
- Why (lightly) — curiosity gets the snapshot; anything that smells like a trading decision gets the snapshot plus the this-is-not-the-data-for-that sentence
Framework: The Fetch and the Fences
- The call:
curl -s -A "Mozilla/5.0" "https://query1.finance.yahoo.com/v8/finance/chart/AAPL?range=1d&interval=1d"— themetaobject carriesregularMarketPrice,previousClose,regularMarketTime(epoch — convert and show),currency,exchangeName. History:range=1mo&interval=1d→ thetimestamp+indicators.quotearrays. The User-Agent header is required — without it the endpoint often refuses. - Unofficial means fragile, and the skill says so: the endpoint is publicly served but undocumented; it can reshape or gate without notice. On a weird response: report it, don't improvise a price. The source line always reads "Yahoo Finance public endpoint (unofficial)."
- Timestamp and delay honesty:
regularMarketTimegets converted and displayed; outside market hours the snapshot says "as of Friday's close" not "currently"; data may be delayed 15+ minutes depending on exchange — flagged, not assumed away. - Currency and exchange discipline: the
currencyandexchangeNamefields are printed with the price — a right number in an unstated currency is a wrong number. - The advice fence is absolute: no buy/sell/hold, no price targets, no pattern-reading, no "looks like a good entry." "Should I buy?" gets the snapshot, the volatility fact, and the clean refusal — same posture as crypto-prices, because the reasons are identical.

Output Format
[Ticker] — [exchange, currency]
[Price] · [±change, ±%] on the day · as of [converted timestamp] ([market open / after close])
[Day range · volume · on request: 52-week position, the 1-month shape in one descriptive sentence]
Source: Yahoo Finance public endpoint (unofficial; may be delayed) · rerun: [exact curl]
Informational snapshot, not investment advice or trading-grade data — decisions belong on a brokerage feed.
Quality Checks
- The ticker's exchange and currency are printed with the price
- The timestamp is converted and the open/closed state stated
- The unofficial-and-possibly-delayed line appears verbatim in spirit
- Weird responses are reported, never smoothed into a made-up price
- The no-advice fence held, including against indirect asks
Anti-Patterns
- Do not answer prices from memory — a remembered stock price is historical fiction
- Do not resolve ambiguous tickers silently — the wrong listing is the classic confident error
- Do not describe chart history in predictive language — shapes are described, futures are not
- Do not present this endpoint as trading-grade — the fence is part of the answer
- Do not give investment advice under any phrasing — the refusal is the skill working
Example Trigger Phrases
- "What's this stock at?"
- "How did the market do today?"
- "Get me a ticker's recent range."
