What is FYERS AI Skills

Skills are packaged units of expertise that extend an AI coding assistant (such as Claude Code) with domain-specific knowledge, ready-to-use scripts, and hard safety rules. Instead of the assistant relying only on its general training, a Skill gives it:

Curated reference docs

the exact API paths, payloads, enum codes, and error semantics for a specific platform.

Battle-tested scripts

reusable code the assistant can call or adapt rather than reinventing (and getting wrong).

Guardrails

non-negotiable rules baked into the workflow (e.g. "dry-run by default", "never hardcode secrets") so generated code is safe on the first pass.

A routing map

the assistant loads only the reference it needs for your task, keeping context lean and answers accurate

What's Inside the FYERS AI Skills

The FYERS AI Skill targets the official FYERS Developer API v3 and treats real-money trading with the seriousness it deserves — safety-first, accurate, and complete end-to-end.

Component
What it is
How it helps you
references/auth.md + fyers_login.py
OAuth login & daily token cache
Handles the full generate-authcode → validate-authcode → access_token flow and caches the daily token, so you never wire up auth by hand.
references/market-data.md + fyers_client.py
Quotes, depth, history, market status
Fetch live quotes, market depth, and historical candles through one authenticated, rate-limit-aware client.
option_chain.py + market-data ref
Option chain, greeks, IV, PCR, expiry, ATM/ITM/OTM, max pain
Token-free helpers to parse chains, find ATM strike, filter expiries, compute PCR, straddle cost, and max pain for options strategies.
references/orders.md + fyers_client.py
Place / modify / cancel / GTT / smart orders, positions
Safe order lifecycle management with dry-run default and symbol validation enforced before every order.
references/symbols.md + fyers_symbols.py
Symbol strings & name → exact symbol
Resolve a human name into the exact eq/fut/opt symbol and get lot/tick/expiry — no token needed (public master files).
references/websocket.md
Live streaming (data / order / TBT sockets)
Correctly stream live ticks and order updates over WebSocket instead of hammering /quotes with polling.
references/backtesting.md + example_strategy.py
Backtest a strategy from historical candles
End-to-end template: fetch candles → generate signal → dry-run order. Copy, adapt, and go live only with an explicit --live.
references/endpoints.md
Full path/field/enum-code catalog
The authoritative catalog so every endpoint path, field, and enum code is exact.
references/rate-limits.md
Rate limits, error codes, retries
Understand and respect the 429/Retry-After rules and per-day caps so you don't get blocked.
helper.py
Token-free order utilities
Lot/qty validation, price rounding to tick size, expiry/DTE parsing, and order_checks() — all pre-order safety checks in one call.
trade_logger.py
Append-only JSONL audit log
Auto-logs every order attempt to ~/.fyers/trades.jsonl; tail/summary give you an auditable trail of what the automation did.

What makes FYERS AI Skills the best

The FYERS AI Skill targets the official FYERS Developer API v3 and stands out because it treats real-money trading with the seriousness it deserves

Safety-first by design

Order-placing code defaults to DRY_RUN, secrets come only from environment variables, symbols are validated against the daily master before any order, and live placement demands an explicit opt-in. You get code that won't burn real capital by accident.

Accurate, not approximate

Enum codes (order type, side, product type, exchange IDs), endpoint paths, and error codes are documented exactly — no guessing, no silent bugs that only surface with live money.

Complete coverage

Auth/OAuth, market data, option chains & greeks, orders/GTT, symbol resolution, WebSocket streaming, backtesting, and rate-limit handling are all covered end-to-end

Production-grade tooling

A reusable REST client, an append-only trade audit log, token caching, and rate-limit (HTTP 429) handling ship in the box

Respects the platform

Built-in awareness of rate limits (10/sec, 200/min, 100k/day), daily token expiry, and WebSocket-vs-polling best practice keeps you from getting throttled or blocked.

FYERS MCP is a connectivity and workflow tool. AI-generated responses may be incomplete or inaccurate and should be reviewed before making trading or investment decisions. FYERS does not provide investment advice through MCP.

Benefits of Using AI Coding Terminals with FYERS AI Skills + MCPs

Combining an AI coding terminal (like Claude Code) with the FYERS AI Skill — and optionally MCP servers for external data and services — is a force multiplier:

From prompt to production faster

Describe the strategy in plain English; the terminal generates working, safety-guarded Python using the exact SDK and endpoints.

Fewer costly mistakes

Guardrails (dry-run, secret hygiene, symbol validation) prevent the class of bugs that lose real money in live trading.

Context stays clean

The Skill's routing map loads only the reference needed per task, so the assistant stays accurate and focused instead of drowning in docs.

MCPs extend reach

MCP servers let the same terminal pull in market news, databases, spreadsheets, notifications, or brokerage tooling — so a single agent can research, code, backtest, and alert without you switching tools.

Verifiable output

The assistant compiles/imports generated code and can run data-only paths against the live API, proving correctness before you ever risk capital.

Auditability built in

Every order attempt is logged, giving you a defensible trail for compliance and debugging.

Set-up in Minutes

npx skills add FyersDev/fyers-skills          # project-level (./)
npx skills add FyersDev/fyers-skills -g        # global (user-level)
npx skills add FyersDev/fyers-skills --all     # all skills, all detected agents, no prompts

This reads SKILL.md, installs the skill as fyers-skills, and wires it into the agent directories it detects. Useful flags: -a/--agent <agents> to target specific agents, -l/--list to preview without installing, --copy to copy files instead of symlinking. List or remove later with npx skills list / npx skills remove fyers-skills.

Requires a public repo. skills add fetches over public GitHub and has no private-repo/token support — if FyersDev/fyers-skills is private the command 404s. Make the repo public, or use the manual install below.
