BB walletchan

Drive the WalletChan browser extension as a human-in-the-loop co-pilot for web3 dapps. The agent navigates the dapp UI and surfaces each transaction or signature — decoded and human-readable — inside the extension for the user to review. A scoped, user-controlled "Agent Password" unlocks ONLY the review-and-confirm UI; it cannot export private keys, reveal the seed phrase, change security settings, or disable auto-lock. Use when the user asks to connect a wallet, swap tokens, supply/deposit to DeFi, sign typed data, or check on-chain balances through a dapp. Requires Chrome with remote debugging and the WalletChan extension installed.

What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Risky intent medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

The purpose itself is risky: wallets, browser password stores, offensive security. Even an honest implementation gives the agent access to things that cost money.

For the author

Explain in the description why the access is needed and how it is limited; add tests that show refusals on dangerous requests.

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

    External checks

    ClawHub: clean
    WalletChan is a clearly disclosed wallet co-pilot skill, but it should be used carefully because it can help confirm crypto transactions through a browser extension.
