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 | $0.00070 | $0.01299 |
| Opus 5 | $0.00035 | $0.00649 |
| Sonnet 5 | $0.00014 | $0.00260 |
| Haiku 4.5 | $0.00007 | $0.00130 |
Grade A, and why
revx-monitor 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Monitoring (revx monitor)
Live price and technical indicator alerts. Runs as a continuous polling process.
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.
If Telegram connectors are configured (see revx-telegram skill), alerts are sent as notifications.
Behavioral Instructions for Claude
Long-Running Commands
All revx monitor <type> commands run indefinitely (polling loops with live dashboard output).
How to handle:
- Run the command using the
Bashtool withrun_in_background: true— this frees Claude immediately while the process runs asynchronously - Periodically read the background task output file with the
Readtool to monitor status and report key events to the user (alerts triggered, errors) - If the user asks to stop, use the
TaskStoptool with the task ID - Also print the command to the user so they can optionally run it in a separate terminal for the full live dashboard experience (with colors, real-time tables, Ctrl+C to stop)
Example — starting a monitor:
Bash tool call:
{ "command": "revx monitor price BTC-USD --direction above --threshold 100000", "run_in_background": true }
Response to user:
Started monitoring BTC-USD price in the background. I'll check for alerts periodically.
If you'd like to see the live dashboard, run this in a separate terminal:
revx monitor price BTC-USD --direction above --threshold 100000Press Ctrl+C to stop. Alerts will also be sent to Telegram if configured.
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-monitor is a skill published in the GitHub repository revolut-engineering/revolut-x-api (64 stars, last pushed yesterday), licensed MIT. It adds 70 tokens to every session and 1,299 once invoked, about $0.0003 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.
