Polar

What it does

When your agent uses it

• Merchant of record
• Tasks that involve DataFrames

Example prompts

• “/polar”

Requirements

• Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Polar is the merchant of record: 4% + 40c per transaction, no monthly fee; it handles tax. Reads move no money.
2. 2checkout-create and refund-create move money: confirm the product, amount, and recipient with the user before running, unless standing…
3. 3Rate limits are 500 req/min production and 100 req/min sandbox; on HTTP 429 the CLI reports the Retry-After hint, then back off.
4. 4Reading (orders, subscriptions, products, customers) needs no confirmation.
5. 5Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/polar.py). Do not print, log, or transmit the token value.

What it can do on your machine

Read from SKILL.md and the folder at commit d6dc5d8. 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

  Ships script files (Python), which the agent can run.

  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 no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Polar loads about 665 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 222 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~39

When it runs · the whole SKILL.md, loaded when a task matches

~665

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

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.
