It took me long enough, but I’m happy to report that the next version of my context sensing toolkit will include some new functionality provided via AppleScript.

First of all, you can query the system for current predictions and observations:

tell application "Pennyworth"
  value of prediction named "Location"
end tell

might return something like Home. Likewise,

tell application "Pennyworth"
  value of observation named "Desktop Observer (Running)"
end tell

might return something like Safari.

Secondly, if you use other apps that call AppleScripts in response to events, you can now instruct the system to log the observation using

tell application "Pennyworth"
  log "My Observation" from observer "My Custom Observer" with duration 10
end tell

This is equivalent to an internal observer logging observations. The “from observer” and “with duration” parameters are optional. The system will choose reasonable defaults if left empty.

This functionality has been requested from a few users, so I’m glad that it is now working. If you have any comments or questions, please post them in the comments below.
