claw

A command-line tool for sending prompts from a terminal to a Breadbrich Engels agent container. A container is an isolated environment that runs the agent and its dependencies.

In plain words
What is it for?
Use it to send prompts, resume sessions, list groups, pipe automated input, choose a container runtime, and read the response in the terminal.
Why use it?
It lets developers use registered agent groups without opening a chat application and supports scripting through standard input.

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

claw 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 2d 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.

Origin

This is a copy

86% identical to claw — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

claw — Breadbrich Engels CLI

claw is a Python CLI that sends prompts directly to a Breadbrich Engels agent container from the terminal. It reads registered groups from the Breadbrich Engels database, picks up secrets from .env, and pipes a JSON payload into a container run — no chat app required.

What it does

  • Send a prompt to any registered group by name, folder, or JID
  • Default target is the main group (no -g needed for most use)
  • Resume a previous session with -s <session-id>
  • Read prompts from stdin (--pipe) for scripting and piping
  • List all registered groups with --list-groups
  • Auto-detects container or docker runtime (or override with --runtime)
  • Prints the agent's response to stdout; session ID to stderr
  • Verbose mode (-v) shows the command, redacted payload, and exit code

Prerequisites

  • Python 3.8 or later
  • Breadbrich Engels installed with a built and tagged container image (breadbrich-agent:latest)
  • Either container (Apple Container, macOS 15+) or docker available in PATH

Install

Run this skill from within the Breadbrich Engels directory. The script auto-detects its location, so the symlink always points to the right place.

1. Copy the script

mkdir -p scripts
cp "${CLAUDE_SKILL_DIR}/scripts/claw" scripts/claw
chmod +x scripts/claw

2. Symlink into PATH

mkdir -p ~/bin
ln -sf "$(pwd)/scripts/claw" ~/bin/claw

Make sure ~/bin is in PATH. Add this to ~/.zshrc or ~/.bashrc if needed:

export PATH="$HOME/bin:$PATH"

Then reload the shell:

source ~/.zshrc   # or ~/.bashrc

3. Verify

claw --list-groups

You should see registered groups. If Breadbrich Engels isn't running or the database doesn't exist yet, the list will be empty — that's fine.

Usage Examples

# Send a prompt to the main group
claw "What's on my calendar today?"

# Send to a specific group by name (fuzzy match)
claw -g "family" "Remind everyone about dinner at 7"

# Send to a group by exact JID
claw -j "[email protected]" "Hello"

# Resume a previous session
claw -s abc123 "Continue where we left off"

# Read prompt from stdin
echo "Summarize this" | claw --pipe -g dev

# Pipe a file
cat report.txt | claw --pipe "Summarize this report"

# List all registered groups
claw --list-groups

# Force a specific runtime
claw --runtime docker "Hello"

# Use a custom image tag (e.g. after rebuilding with a new tag)
claw --image breadbrich-agent:dev "Hello"

# Verbose mode (debug info, secrets redacted)
claw -v "Hello"

# Custom timeout for long-running tasks
claw --timeout 600 "Run the full analysis"

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
