VerifiedTrustedCommunity
HSM-backed secret management for AI agents. Store API keys (including Bankr `bk_` keys), passwords, and credentials in an encrypted vault; retrieve them at runtime via MCP without keeping secrets in chat context. Policy-based access control, secret rotation, sharing, EVM transaction intents (sign/simulate/broadcast), multi-chain signing keys, treasury multisig proposals, OIDC federation for external service auth, built-in prompt injection detection, and optional Shroud TEE LLM proxy. Use when the agent needs secure credential storage, just-in-time secret access, guarded on-chain signing, or security scanning — not for Bankr trading prompts, portfolio checks, or x402 calls (use the bankr skill instead).

testing
VerifiedTrustedCommunity
Stake $GEM tokens on Gem Miner (gemminer.app) to earn yield and unlock the in-game earn/cashout system. Use when the user wants to stake GEM, check their staking balance or rewards, unstake, claim rewards, or check whether they meet the 25M GEM gate. Base mainnet only.

bankrbot/codegrid
development
VerifiedTrustedCommunity
CodeGrid is a native macOS canvas where multiple coding agents (Claude, Codex, Gemini, Cursor, Grok, shells) run side by side in panes and collaborate via a local agent bus — no tmux, no cloud, no account, no stored API keys. Install this skill when an agent should know how to operate inside a CodeGrid pane, drive the workspace from outside (control socket or codegrid:// deep links), spawn or message sibling agents, or coordinate multi-agent work (delegate, review, pipeline, parallel fan-out, monitor, debate). The differentiator: multiple coding agents collaborating on one canvas, addressable by stable session_id, with a read → message → read protocol built for orchestration.
