groups

A command for listing WhatsApp groups and their Community structure. It shows Community parent groups, their subgroups, announcement channels, and ordinary groups.

In plain words
What is it for?
Displaying all known groups, nesting subgroups under their Communities, and optionally showing only groups the assistant can use.
Why use it?
It helps users understand which groups exist and whether the assistant has no access, read-only access, or full read-and-write access.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

groups 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 yesterday.

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

List WhatsApp groups using the wu MCP server.

By default wu_groups_list returns ALL known groups (the discovery surface) so the user can see JIDs to opt into via wu config allow <jid>. The constraint field tells you the current state: full (read+write), read (read-only), or none (not opted in).

Render the result so the user can see community structure:

  • Group rows with is_community: true are community parents.
  • Rows with linked_parent: <parent-jid> are subgroups; indent them under their parent.
  • Rows where is_community_announce: true are the community's announcement channel — call them out separately.
  • Plain groups (no linked_parent, not a community) go after the community trees.

If the user asks for "groups I'm in" without further qualification, show everything. If they ask for "groups Claude can read or send to," pass allowed_only: true.

Changes

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.

groups is a command published in the GitHub repository ibrahimhajjaj/wu-cli (14 stars, last pushed 19d ago), licensed MIT. It adds 7 tokens to every session and 241 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
