alpaca
Alpaca brokerage — US stocks & ETFs. Account, positions, orders, quotes, history, and order placement (paper + live). Use when the user wants to check or trade a US-stock account on Alpaca (e.g. "Alpaca buying power", "buy 1 AAPL on Alpaca paper", "my Alpaca positions"). Cloud API, runs directly in the container.
What this skill does
## What this is ☁️ **Cloud broker** — Alpaca exposes a public REST API, so this runs **directly in the Starchild container**, no local gateway needed. US equities and ETFs. Paper and live are fully separated: **different key pairs, different hosts** (`paper-api.alpaca.markets` vs `api.alpaca.markets`). A paper key physically cannot touch the live account. Live order placement additionally requires the `--confirm-live` flag. ## Get your API keys 1. Sign up at [alpaca.markets](https://alpaca.markets) (US brokerage; paper trading is free and needs no funding). 2. **Paper keys:** log in → switch to **Paper Trading** (toggle top-left) → **Home** → "API Keys" panel → **Generate New Keys**. Copy the **Key ID** and **Secret Key** (secret shown once). 3. **Live keys (optional, real money):** switch to **Live Trading** → same API Keys panel → generate. These are a *different* pair from paper. 4. Market data: the free **IEX** feed works out of the box. **SIP** (full-market) needs a paid data subscription. ## Configure (.env) Request via secure input — never paste keys in chat. Variables: | Variable | Required | Notes | |---|---|---| | `ALPACA_API_KEY` | yes (paper) | paper Key ID | | `ALPACA_SECRET_KEY` | yes (paper) | paper Secret | | `ALPACA_LIVE_API_KEY` | only for live | live Key ID | | `ALPACA_LIVE_SECRET_KEY` | only for live | live Secret | | `ALPACA_FEED` | no | `iex` (default) or `sip` | ## Usage `pip install alpaca-py` (first run). All commands print JSON. Default profile is `paper`. ```bash python skills/alpaca/scripts/alpaca_cli.py status python skills/alpaca/scripts/alpaca_cli.py account python skills/alpaca/scripts/alpaca_cli.py positions python skills/alpaca/scripts/alpaca_cli.py orders [--executions] python skills/alpaca/scripts/alpaca_cli.py quote --symbol AAPL python skills/alpaca/scripts/alpaca_cli.py history --symbol AAPL --period 1d --limit 90 # place (paper): qty OR notional, market OR limit python skills/alpaca/scripts/alpaca_cli.py place --symbol AAPL --side buy --qty 1 --type market python skills/alpaca/scripts/alpaca_cli.py place --symbol AAPL --side buy --notional 500 --type limit --limit-price 180 python skills/alpaca/scripts/alpaca_cli.py cancel --order-id <id> # live: must add --profile live AND --confirm-live python skills/alpaca/scripts/alpaca_cli.py --profile live --confirm-live place --symbol AAPL --side buy --qty 1 ``` Periods: `1m 5m 15m 30m 1h 1d 1w 1M`. Alpaca supports fractional `--notional` (dollar amount) orders. ## Gotchas - `status` is the health check — it reports SDK install state, key presence, and pings the account. Run it first. - Free IEX data can be sparse/delayed off-hours; use `sip` only if the account has the paid feed. - Live trading is real money. The `--confirm-live` gate is intentional; never auto-add it.

jfrog
IncludedInteract with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.
cupynumeric-migration-readiness
IncludedPre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.
alibabacloud-data-agent-skill
IncludedInvoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".
token-optimizer
IncludedReduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
resend-cli
IncludedUse this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
alibabacloud-odps-maxframe-coding
IncludedUse this skill for MaxFrame SDK development and documentation navigation on Alibaba Cloud MaxCompute (ODPS). Helps answer MaxFrame API, concept, official example, and supported pandas API questions; create data processing programs; read/write MaxCompute tables; debug jobs (remote or local); and build custom DPE runtime images. Trigger when users mention MaxFrame, MaxCompute with MaxFrame, ODPS table processing, DPE runtime, MaxFrame docs/examples, DataFrame/Tensor operations, or GPU runtime setup. Works for both English and Chinese queries about Alibaba Cloud data processing with MaxFrame.
