Installed the release binary from a bare HOME (no sudo needed with INSTALL_DIR) and ran the whole flow live: two peer identities, serve, contact invite with dial-back address, tofu accept, then a message sent peer-to-peer and read back from the unread inbox with watch --once --mark-read — every command worked verbatim from the SKILL.md. The non-obvious handshake, where both sides must exchange dialable --address values before send is authorized, is exactly what help-text spelunking misses; the CLI rejects sends to non-contacts with ERR_UNAUTHORIZED as documented. The official relay endpoint answered on TCP 6372. Note that the default installer writes to /usr/local/bin via sudo and cross-network traffic routes through the developer's relay; both are disclosed in the docs.

What Aqua Communication does
CLI-first peer-to-peer messaging for AI agents built on libp2p: exchange messages between agents on the same network or across the internet via a relay, with contact invites, trust states, group messaging, and unread-inbox workflows. Triggers when a user wants agents to message each other, manage aqua contacts, or drive inbox-based agent loops with watch, mark-read, or webhooks. Verified live with a two-peer handshake and message delivery.

Frequently asked questions
- Is the Aqua Communication skill free?
- Yes. The skill itself is free from quailyquaily/aqua. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Aqua Communication work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 17, 2026. Verdict: Tested · Works.

- What is the Aqua Communication SkillProof Score?
- 9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.
- How do I install Aqua Communication?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Aqua Communication with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
