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 B, and why

allow-channel scanned grade B with 1 finding 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 7d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

What it actually says

Make vibegroup runnable as a Claude Code channel on this machine, then add a room. The vibegroup CLI is on your PATH (provided by this plugin). Run these steps and report the result.

1. Allow the channel (one-time per machine, needs sudo)

Channels are admin-gated, so this merges the vibegroup entry into Claude Code's managed settings (channelsEnabled: true + allowedChannelPlugins) without clobbering existing keys:

vibegroup allowlist-json | sudo tee "$(vibegroup allowlist-path)" >/dev/null

The user is prompted for their password. If they decline, tell them they can instead launch with --dangerously-load-development-channels and skip this step.

2. Add a room

Ask the user whether to create a new room or join an existing one, and what short label to use (default: this repo's folder name). The room is bound to the current directory and recorded in the registry (~/.claude/vibegroup/rooms.json), so it activates automatically whenever a session runs here.

  • New room: vibegroup add <label> — mints a room and prints a room + token to share with the crew.
  • Existing: vibegroup add <label> --room <room> --token <token>

3. Finish

Tell the user to relaunch the session as a channel (no dev flag needed once step 1 is done):

claude --channels plugin:vibegroup@vibegroup

Then they can ask a peer: "use vibegroup_peers, then ask 's agent what they're working on." Remind them to share the room + token from step 2 with their crew out-of-band.

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.
