Vibsync setup

Vibsync setup is a skill for Claude Code, Codex from loosedays/vibsync-mcp. It costs 65 tokens per session (532 once invoked), scanned A, original, MIT.

Setup and troubleshooting instructions for connecting the Vibsync MCP server, a shared team service for AI coding agents. It covers browser sign-in, team approval, and checking that the connection and first handoff work.

In plain words
What is it for?
Use it to connect Vibsync with browser OAuth, verify the team and member, load team context, and test saving and retrieving a handoff.
Why use it?
It explains the difference between installing the plugin and actually connecting it, and helps diagnose missing Vibsync tools.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Vibsync setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Vibsync setup & troubleshooting

Vibsync gives your AI coding agents a shared team brain — long-term memory of decisions and product knowledge, async agent Q&A, task coordination, and file-claim conflict avoidance — over a remote MCP server at https://mcp.vibsync.com/mcp. On connect, the server itself tells the agent how to use its tools; this skill only covers getting connected and verifying it.

Connect (one time)

  1. This plugin bundles the Vibsync MCP server. On first use, Claude Code opens your browser to sign in and authorize. When asked, approve the team you want to work in. No token or secret to copy — it's browser OAuth.
  2. Confirm it's live: call the whoami tool — it returns your team and member. Then call onboard to pull the team's current context.

Installing the plugin is not the same as connecting. A connection exists only after you complete the browser OAuth above and your agent makes a real request.

Verify the handoff (the whole point of Vibsync)

  1. Save one real decision: ask the agent to record it with remember (e.g. "API errors use RFC 9457 Problem Details").
  2. Start a new conversation in the same project and ask, citing the source: "From Vibsync, what did we decide for this project? Cite the source." If it answers from Vibsync, the handoff works — that's Vibsync, not the tool's own memory.

Troubleshooting

  • Vibsync tools missing: confirm the plugin is installed and enabled (/plugin), then complete the one-time browser OAuth above.
  • Wrong or empty team: you may have authorized a different team, or the team is new and empty. A credential belongs to exactly one team, so connect again to work in another team.
  • Handoff didn't carry over: make sure it's a NEW conversation in the same project, that the reply cites Vibsync, and that the earlier remember actually saved.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
