Tools & capabilities
Capsulate tools 54
capsulate_launchLaunch a new isolated cloud sandbox (capsule) and (by default) wait until it is ready. Returns the capsule id and connection info. Use the returned sessionId for exec/files/etc. With skill, the capsule is the skill's environment (its saved template with the software set up) and the skill's setup procedure has run, so you can use its procedures right away.capsulate_listList the team's active capsules.capsulate_getFetch a capsule's full details by id.capsulate_destroyTerminate a capsule and release its resources.capsulate_execExecute a command inside a capsule and return stdout, stderr, and the exit code. Provide the command as an argv array, e.g. ['ls','-la','/workspace']. Commands first: files, installs, settings, scripts and data are one call here, a fraction of a second, where the screen takes many steps. On a Linux desktop capsule it runs as the desktop user 'capsulate' (home folder, DISPLAY :1, so apps open on the shared screen); prefix 'sudo' for root. On Windows pass ['powershell.exe', '-Command', '<script>']: it runs in the desktop session's PowerShell, about 0.3 s. It works while a person holds the screen.capsulate_run_codeRun a snippet of code inside a capsule: python, node or bash on Linux, powershell on Windows (about 0.3 s). Returns stdout/stderr/exit. Faster than doing the same on the screen.capsulate_write_fileWrite a UTF-8 text file inside a capsule (the folder is created). One call, far faster than typing it into an editor on the screen; open it afterwards with capsulate_open if the person should see it.capsulate_read_fileRead a UTF-8 text file from inside a capsule. One call, no screen needed.capsulate_set_envSet environment variables inside a running capsule.capsulate_screenshotCapture a screenshot of a desktop capsule. Returns the image so you can see the screen. For a smaller, faster image ask for format 'jpeg', a scale such as 0.5, or only a region (x, y, w, h) of the screen; the text after the image says how its points map back to screen pixels, which click and the other tools take.capsulate_clickClick at pixel (x, y) in a desktop capsule. Pass screenshot:true to see the screen after the click.capsulate_typeType text into the focused field of a desktop capsule.- +42 more on the listing page
