Agent Wormhole
Agent Wormhole opens a temporary encrypted passage for agent handoffs. The payload can be claimed once, then the channel collapses.
Before First Use
This skill executes the @builtbyecho/agent-wormhole npm package. Before running any agent-wormhole or npx @builtbyecho/agent-wormhole command for the first time in a session, tell the user:
About to install/run
@builtbyecho/agent-wormhole(v0.1.2) from npm. It is an encrypted one-time-handoff CLI that writes payloads to a local.agent-wormholes/directory and (for holder/paid opens) callsstorage.builtbyecho.xyzand the Bankr x402 endpoint. It does NOT sign transactions or access private keys.Proceed? (y/n)
Wait for explicit confirmation before the first invocation. Subsequent calls in the same session do not need to re-prompt.
Pin the version when invoking via npx:
npx -p @builtbyecho/[email protected] agent-wormhole <args>

https://www.npmjs.com/package/@builtbyecho/agent-wormhole - Hosted skill file:
https://www.builtbyecho.xyz/skills/agent-wormhole/SKILL.md
Use this skill when a task involves:
- sending or receiving one-time agent handoffs
- passing mission briefs, configs, receipts, files, or scoped secrets
- using the
agent-wormholeCLI or HTTP API - checking ECHO holder sponsored access
- checking Bankr x402 paid open status
- deploying or operating the VPS service
Quick Commands
From a project that has the package installed:
agent-wormhole send --text "mission brief" --ttl 10m
agent-wormhole send --file ./artifact.tgz --note "handoff bundle"
agent-wormhole inspect <code>
agent-wormhole receive <code> --out ./received
agent-wormhole cleanup --delete-claimed-older-than 15m
For one-off use without installing globally:
npx -p @builtbyecho/[email protected] agent-wormhole send --text "mission brief"
Mental Model
- Codes are
id.secret. idlocates stored metadata.secretderives the AES-256-GCM decrypt key and is not stored.- Default TTL is 10 minutes.
- Max TTL is 24 hours unless explicitly configured lower.
- Default max payload is 5 MB.
- Receipts are written for opens and claims.
Access Paths
- Local CLI/library opens record
access.path = local. - Direct API holder opens require an EIP-191 signature from a wallet holding at least
50,000,000 ECHOon Base and recordaccess.path = echo_holder. - Bankr x402 paid opens are handled by
agent-wormhole-openand recordaccess.path = x402_paid. - Claiming is free.
Live Endpoints
- Direct holder/API route:
https://storage.builtbyecho.xyz/agent-wormhole - Bankr x402 paid open:
https://x402.bankr.bot/0x2a16625fad3b0d840ac02c7c59edea3781e340ae/agent-wormhole-open - Self-hosted local service default:
http://127.0.0.1:8791
Verification
From the package root:
npm test
node --check src/cli.js
node --check src/index.js
node --check src/server.js
npm pack --json --dry-run
For live health:
curl -sS https://storage.builtbyecho.xyz/agent-wormhole/health
For Bankr status, check both registry and execution:
bankr --config "$BANKR_OWNER_CONFIG" x402 list
bankr x402 schema https://x402.bankr.bot/0x2a16625fad3b0d840ac02c7c59edea3781e340ae/agent-wormhole-open
bankr --config "$BANKR_PAYER_CONFIG" x402 call -X POST -d '{"payload":"dGVzdA=="}' --max-payment 0.01 -y --raw https://x402.bankr.bot/0x2a16625fad3b0d840ac02c7c59edea3781e340ae/agent-wormhole-open
Set BANKR_OWNER_CONFIG to the endpoint owner/operator config and BANKR_PAYER_CONFIG to a separate payer config. Do not treat registry active status alone as proof that paid x402 execution works. A real paid call from a non-owner wallet is the proof.
Safety
- Do not paste wormhole codes into public channels unless the user explicitly wants the payload claimable by anyone there.
- Do not log plaintext secrets or payloads.
- Prefer short TTLs for secrets.
- Use local cleanup commands for received artifacts when they are no longer needed.
- Do not test Bankr paid endpoints with the same wallet that owns/deployed the endpoint.

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).

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.
