Code Review
This pull request introduces comprehensive documentation for Signal bot integration, which is a valuable addition. The new documentation is well-structured and detailed. My review includes a few suggestions to correct factual errors in the setup instructions, a high-severity fix for an unsafe code example that now includes a reference to best practices for preventing injection vulnerabilities, and some minor improvements for maintainability by sorting lists of items.
Note: Security Review is unavailable for this PR.

The minimal bot example constructs the JSON payload for the curl request using string interpolation. This is unsafe and will fail if the incoming message variable contains characters that break JSON syntax, such as double quotes. To make the script robust, you should use jq to safely construct the JSON payload. The suggested change is slightly more verbose but ensures correctness and security.

- To avoid injection vulnerabilities when constructing data dynamically in shell scripts, use robust tools like
jqfor JSON instead of string interpolation, similar to how bash arrays are preferred overevalfor command arguments.

For better readability and maintainability, it would be beneficial to keep the list of communication subagents sorted alphabetically.

There was a problem hiding this comment.
The documentation states that signal-cli requires JRE 25+. This appears to be a typo. The official signal-cli documentation specifies Java 17 or newer, and Java 25 has not yet been released. Please correct the required JRE version to reflect the actual requirement.

The symbolic link path for the GraalVM native binary installation appears to be incorrect. The tar command extracts into a versioned directory (e.g., /opt/signal-cli-0.13.2), but the ln command points to a non-versioned path /opt/signal-cli. This will likely cause the command to fail. The path should be versioned, consistent with the JVM build instructions.
