What it does

Coffer is an agent skill from BankrBot/skills. Earn fees by depositing ETH into the Coffer Vault, a multi-strategy managed liquidity vault. Query and transact Coffer, run by Soteria Labs on Robinhood (4663) - one share over several Uniswap V3 legs (volatile + stock pairs). Deposit ETH, burn liquid shares to withdraw WETH, read vault value / total shares / my shares / fees / rotating tokens / live stock pairs. Use when the user asks about Coffer, the coffer vault, stock pairs in Coffer, or Coffer deposits and withdrawals. Not for Auto vaults or UFloat.

Its SKILL.md is about 3.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `catalog.json`, `references/abi-and-calls.md` and `references/addresses.md`).

It sits in Business, Finance & HR. It works with Uniswap. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.

Context cost

Coffer loads about 3.7k tokens when it runs, and up to ~7.3k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 2,002 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~129
When it runs · the whole SKILL.md, loaded when a task matches: ~3.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~7.3k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 2,002 words (~3,733 tokens).

“One vault. Chain is always Robinhood (4663). Do not ask for chain, Uniswap version, or Auto factory. Do not scan AutoVault factories.”
