Polymarket Trading
BlockRunAI/ClawRouter
A skill your agent uses when the user wants to actually PLACE, manage, or redeem bets on Polymarket (not just read odds — that's the blockrunpredexon data tools).
Connect this Bankr account to the user's Harness account (tryharness.ai) and manage everything Harness-side from here.

What it does
Harness is an agent skill from BankrBot/skills. Connect this Bankr account to the user's Harness account (tryharness.ai) and manage everything Harness-side from here. Pair with a signed wallet proof, then inspect the Harness trading wallet and portfolio, fund it on the user's request, request withdrawals back to this wallet, buy Harness credits with $HARNESS over x402, watch, pause, or cancel Harness agent sessions and their artifacts, and revoke the trading wallet outright if anything looks wrong. Use whenever the user mentions Harness, their Harness wallet…
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `catalog.json` and `references/management-api.md`).
It sits in Business, Finance & HR, covering Trading and backtesting. It works with x402. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.
When your agent uses it
- The user mentions Harness
- Their Harness wallet
- Moving funds between Bankr and Harness
Example prompts
- “/harness”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit dc47eed. 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.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
tryharness.ai
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
Harness loads about 2.7k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 145 tokens; SKILL.md has 1,538 words of instructions outside code blocks.
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 1,538 words (~2,696 tokens).
“Harness (tryharness.ai) is a screen-aware assistant. Every Harness user gets a provisioned Bankr trading wallet that Harness's own agent trades from under user-set caps, and a Harness credit balance that pays for the assistant itself. This skill makes THIS Bankr…”
