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.

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 | $0.00078 | $0.01804 |
| Opus 5 | $0.00039 | $0.00902 |
| Sonnet 5 | $0.00016 | $0.00361 |
| Haiku 4.5 | $0.00008 | $0.00180 |
Grade A, and why
revx-trading 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 12d 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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trading (revx order place / revx order replace / revx order cancel)
Place market and limit orders, replace (modify) open orders, cancel open orders.
Auth required. Make sure
revxis installed and configured before running these commands. If any command fails with an auth-related error —Auth not configured,No private key found,Authentication failed (401),Invalid signature,insecure permissions, or a missing key/config file at~/.config/revolut-x/— invoke therevx-authskill immediately and apply the fix yourself. Do not interrupt the user to ask them to run setup. Only escalate to the user for steps only they can perform (pasting the API key, registering the public key in their Revolut X profile, choosing a passphrase). After the fix, retry the original command.
Symbols use BASE-QUOTE format with a dash: BTC-USD, ETH-EUR, SOL-USD. Check pair constraints with revx market pairs (see revx-market skill).
order place supports --json or --output json for machine-readable output.
Behavioral Instructions for Claude
Human Confirmation Required
NEVER execute revx order place, revx order replace, or revx order cancel without explicit user confirmation. These commands move real money.
Before running any order command, present a confirmation summary to the user:
Order to place:
- Pair: BTC-USD
- Side: buy
- Type: limit @ $95,000
- Size: 0.001 BTC
Shall I proceed?
Only execute after the user explicitly approves (e.g., "yes", "go ahead", "do it").
For revx order cancel --all, warn the user that this cancels every open order and confirm.
Missing Parameters — Always Ask, Never Guess
All required parameters must come from the user. If any are missing, ask for them before building the command.
Required for every order:
- Symbol — which pair? (e.g.,
BTC-USD) - Side — buy or sell?
- Size — how much? (
--qtyfor base currency or--quotefor quote currency) - Order type — market (
--market) or limit (--limit <price>)?
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-trading is a skill published in the GitHub repository revolut-engineering/revolut-x-api (64 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 1,804 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
