Backtest

marketcalls/vectorbt-backtesting-skills
2.8k installs186 stars
Summary

If you're backtesting Indian equities or futures with VectorBT, this generates complete Python scripts instead of making you wire up data fetching, signal generation, and plotting from scratch every time. It pulls data from OpenAlgo or DuckDB, uses TA-Lib for standard indicators and OpenAlgo's ta library for specialty ones like Supertrend, runs the backtest with proper Indian delivery fees (0.111% plus fixed costs) or F&O rates, and spits out stats, a benchmark comparison table, trade CSVs, and Plotly charts. It includes templates for common strategies like EMA crossover, RSI, MACD, and Donchian channels. The lot size logic for NIFTY and BANKNIFTY futures is built in, which saves you from getting sizing wrong on leveraged products.

lfg

everyinc/compound-engineering-plugin

Run the full autonomous shipping pipeline end-to-end, hands-off with no check-ins: plan, implement, review and fix, commit, push a branch, open a PR, and watch CI to green. Use only when the user explicitly asks to build or ship something autonomously all the way to an open PR, or invokes lfg directly — it pushes and opens a PR without stopping. Not for in-the-loop work where the user reviews each step: use ce-plan to plan, ce-work to implement a plan, ce-debug to fix a bug, or ce-commit-push-pr to commit and open a PR for existing changes.

gh-axi

kunchenguid/gh-axi

Operate GitHub through the gh-axi CLI - issues, pull requests, workflow runs, workflows, releases, repositories, labels, gists, Projects (v2), Actions secrets and variables, search, and raw API access. Use whenever a task touches GitHub: listing or filing issues, reviewing or merging PRs, checking CI runs, triggering workflows, cutting releases, managing Projects boards, managing Actions secrets/variables, or working with gists via `gist list`, `gist view`, `gist edit`, `gist rename`, `gist create`, `gist delete`, or `gist clone`.

fetch

browserbase/skills

Use this skill when the user wants to retrieve a URL without a full browser session: fetch HTML or JSON from static pages, inspect status codes or headers, follow redirects, or get page source for simple scraping. Prefer it over a browser when JavaScript rendering and page interaction are not needed. Supports proxies and redirect control.

adk-eval-guide

google/adk-docs

MUST READ before running any ADK evaluation. ADK evaluation methodology — eval metrics, evalset schema, LLM-as-judge, tool trajectory scoring, and common failure causes. Use when evaluating agent quality, running adk eval, or debugging eval results. Do NOT use for API code patterns (use adk-cheatsheet), deployment (use adk-deploy-guide), or project scaffolding (use adk-scaffold).
