What is revolut-x-api AGENTS.md?

A set of project instructions for Revolut X, an open-source monorepo containing crypto-exchange tools in several packages. A monorepo is one code repository that holds multiple related packages.

Use it when installing dependencies, building packages in order, running tests, or working on the API client, command-line tool, MCP server, or related skills.

It gives a coding agent the project's setup, build, testing, linting, and formatting rules, so work follows the repository's structure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00938	$0.00938
Opus 5	$0.00469	$0.00469
Sonnet 5	$0.00188	$0.00188
Haiku 4.5	$0.00094	$0.00094

Security

Grade A, and why

revolut-x-api AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Revolut X

Open-source monorepo for Revolut X crypto exchange tooling.

Packages

Package	Description
`api/`	Typed HTTP client for Revolut X REST API (zero runtime deps, Node.js built-ins + zod)
`cli/`	`revx` CLI — trading, monitoring, grid bots (Commander.js, chalk, cli-table3)
`mcp/`	MCP server — 23 tools for AI assistants (@modelcontextprotocol/sdk, esbuild bundle)
`skills/`	Claude Code skills for CLI and trading workflows

Setup

npm ci                            # Install all workspace dependencies
npm run build                     # Build all packages

Individual packages (order matters — api first):

cd api && npm run build && cd ..  # HTTP client (dependency for cli and mcp)
cd cli && npm run build && cd ..  # CLI
cd mcp && npm run build && cd ..  # MCP server bundle

Install CLI globally after building:

cd cli && npm link

Testing

npm test                          # All workspaces
npm test -w api                   # API client only
npm test -w cli                   # CLI only
npm test -w mcp                   # MCP server only

Linting & Formatting

npm run lint                      # ESLint across api, cli, mcp
npm run lint:fix                  # Auto-fix
npm run format                    # Prettier
npm run format:check              # Check only

Code Conventions

TypeScript 5.7, strict mode, ESM ("type": "module")
var keyword mandatory for local variables
Decimal.js for all financial math — never use native floats for money
Zod schemas for API response validation
Atomic file writes for state persistence (write to .tmp, then rename)
No comments in production code — code should be self-documenting
Static imports for constants, enums, utility methods

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
