Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00058 | $0.00941 |
| Opus 5 | $0.00029 | $0.00470 |
| Sonnet 5 | $0.00012 | $0.00188 |
| Haiku 4.5 | $0.00006 | $0.00094 |
Grade B, and why
revx-auth scanned grade B with 1 finding 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 10d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Auto-resolve target. When invoked from another
revx-*skill due to an auth error, do not bounce the user back to manual setup. Diagnose the failure against the Error Reference below, run the fix yourself (e.g.chmod 600 ~/.config/revolut-x/private.pem,revx configure generate-keypair,revx configure set --api-key <key>), then return to the calling skill and retry the original command. Only ask the user for inputs that only they can provide: the 64-character API key string, confirmation that they have registered the public key in their Revolut X profile, the keypair passphrase, or approval to overwrite an existing keypair.
Prerequisites
- Node.js >= 20 (check with
node -v) - npm (comes with Node.js)
Install
npm install -g @revolut/revolut-x-cli && npm link @revolut/revolut-x-cli
After install, revx is available as a global command:
revx --version # Should print the version
Getting Started
Step 1: Configure Authentication
revx configure # Interactive setup wizard
This will:
- Generate an Ed25519 keypair (private + public key)
- Display your public key — copy it
- Prompt you to register the public key at exchange.revolut.com -> Profile -> API Keys
- Create a new API key — tick the "Allow usage via Revolut X MCP and CLI" checkbox
- Prompt for the 64-character API key you receive after registration
Or do it step-by-step:
revx configure generate-keypair # Creates Ed25519 keypair
# Register public key at exchange.revolut.com -> Profile -> API Keys
# Create API key — tick "Allow usage via Revolut X MCP and CLI"
revx configure set --api-key <64-char-key>
Step 2: Verify Configuration
revx configure get # Show config status (keys redacted)
revx configure path # Print config directory path
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.

revx-auth is a skill published in the GitHub repository revolut-engineering/revolut-x-api (62 stars, last pushed 5d ago), licensed MIT. It adds 58 tokens to every session and 941 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
