What it does

Kraken Shared is an agent skill from krakenfx/kraken-cli. Shared runtime contract for kraken-cli: auth, invocation, parsing, and safety.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR. The repository describes itself as: The first AI-native CLI for trading crypto, stocks, forex, and derivatives. The licence is MIT.

When your agent uses it

Business, Finance & HR work in your project

Example prompts

“/kraken-shared”

Requirements

A credential in KRAKEN_API_KEY
A credential in KRAKEN_API_SECRET

What it can do on your machine

Read from SKILL.md and the folder at commit aa56e59. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- KRAKEN_API_KEY
- KRAKEN_API_SECRET
- KRAKEN_FUTURES_API_KEY
- KRAKEN_FUTURES_API_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kraken Shared loads about 849 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 386 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~23
When it runs · the whole SKILL.md, loaded when a task matches: ~849

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

kraken-shared

This tool is experimental. Commands execute real financial transactions on the Kraken exchange. Test with kraken paper before using real funds. See DISCLAIMER.md for full terms.

Invocation Contract

Always call:

bash

kraken <command> [args...] -o json 2>/dev/null

Rules:

Parse stdout only.
Treat stderr as diagnostics.
Exit code 0 means success.
Non-zero exit means failure with JSON envelope in stdout.
Streaming commands (session start, record, ws, streamd) emit JSONL: match lines by their "type" field (e.g. scan for "type":"session_started" to get the session handle) — never assume a line position, because live market frames interleave on stdout.
Probe capability, not version, at the start of a loop: kraken session --help >/dev/null 2>&1 exits 0 on a build that speaks this contract and 2 on an older one — kraken --version cannot tell them apart across a vocabulary change.
Market-data field names are readable (last_price, not c[0]). Only ticker still keys on Kraken's INTERNAL pair name (XXBTZUSD, not BTCUSD) — reach its fields with .[] or to_entries, never a hardcoded key. ohlc/trades/spreads reshape to {pair, …}: fold the named row array (.candles/.trades/.spreads) directly, never the whole object — ohlc keeps a sibling last cursor that poisons naive iteration. orderbook drops the wrapper to top-level .asks/.bids.
Validate every number a READ produces before it gates an order or lands in a reason. On an empty or failed read, record kraken session note --kind alert --reason "READ failed: ..." and end the step — never interpolate a failed read into a reason, or the decision log fills with plausible-looking false evidence.

Authentication

bash

export KRAKEN_API_KEY="your-key"
export KRAKEN_API_SECRET="your-secret"

Optional futures credentials:

bash

export KRAKEN_FUTURES_API_KEY="your-futures-key"
export KRAKEN_FUTURES_API_SECRET="your-futures-secret"

Public market data and paper trading require no credentials.

Error Routing

Route on .error:

auth: re-authenticate
rate_limit: read suggestion and docs_url fields, adapt strategy
network: retry with exponential backoff
validation: fix inputs, do not retry unchanged request
api: inspect request parameters

Safety

The catalog marks 41 commands as dangerous: true. Always check the dangerous field in agents/tool-catalog.json before executing a command.

Require explicit human approval before:

live buy or sell orders (spot and futures)
order amendments, edits, and batch operations
cancel and cancel-all operations
withdrawals and wallet transfers
earn allocate/deallocate
subaccount transfers
WebSocket order mutations

Use paper trading for dry runs:

bash

kraken workspace create sandbox --capital 10000 --mode paper -o json
export KRAKEN_WORKSPACE=sandbox

If you hit a mismatch between what you are trying to do and the CLI's interface or responses — including a mismatch between this skill and the installed CLI version's contract — feel free to submit feedback with kraken feedback.
