# LSEG agent skills for Claude Code, Cursor and RevampKey

> Ready-made LSEG playbooks for AI agents: derivatives scenario analysis with LSEG data, fixed income valuation review with LSEG data, check an FX rate against the forward curve and volatility. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Use LSEG data in Claude](https://revampkey.com/marketplace/london-stock-exchange-group/skills/essentials.md): Guides Claude through connecting LSEG data, choosing the right pricing, curve, volatility or reference tool, and labelling licensed data separately from calculated results. Asks before changing the signed-in account.
- [Derivatives scenario analysis with LSEG data](https://revampkey.com/marketplace/london-stock-exchange-group/skills/derivatives-scenario-analysis.md): Builds a base case and shocked values for swaps, options and rate-sensitive positions using LSEG curves and volatility surfaces, and states the shocks and assumptions behind each result. It asks before saving or sharing any output.
- [Fixed income valuation review with LSEG data](https://revampkey.com/marketplace/london-stock-exchange-group/skills/fixed-income-valuation-review.md): Checks a bond or bond future's terms, curves and risk analytics before its value is used, and flags stale or inconsistent inputs. It treats model output as an estimate and asks before changing any saved state.
- [Check an FX rate against the forward curve and volatility](https://revampkey.com/marketplace/london-stock-exchange-group/skills/fx-market-check.md): Tests whether an FX spot or forward level is plausible for a given pair and tenor, by comparing it with licensed spot, forward, forward curve and volatility data. It flags convention and stale-input problems before the number is used, and asks before any change to a booking.
- [Build a macro and earnings brief from LSEG data](https://revampkey.com/marketplace/london-stock-exchange-group/skills/macro-and-earnings-brief.md): Combines IBES consensus, company fundamentals, macro series and recent headlines into a brief that separates sourced facts from interpretation. It reads data only and asks before saving or sharing anything.

### What is a LSEG agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each LSEG skill describes one job, which LSEG tools to use in which order, what to check first and when to stop and ask you.

### Do the LSEG skills change anything on their own?

5 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in LSEG.

### Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect LSEG; elsewhere you copy the folders into your project or skills directory.

### Do I need the LSEG MCP server too?

Yes. The skills tell the agent how to do the work; the LSEG MCP server gives it the tools to do it. The LSEG MCP setup guide covers every client.
