This PR adds the ability to configure the default background behavior via the SUB_AGENT_BACKGROUND_DEFAULT environment variable.

Changes

  • Added SUB_AGENT_BACKGROUND_DEFAULT env var reading in initConfig()
  • When set to 'true', background processing becomes the default
  • Request-level 'background' parameter can still override the default
  • Updated jsonschema description to reflect new default behavior

you have to rebase on top of upstream master, and avoid committing the binary

You didn't rebased, or at least you seem to be really behind and indeed there are conflicts

  2. The binary file removal commit
  3. All latest changes from upstream/master

The PR is now up to date and ready for your review. @mudler

- Add strconv import for parsing boolean environment variable
- Add backgroundDefault package-level variable
- Read SUB_AGENT_BACKGROUND_DEFAULT environment variable in init()
- Update SendInput jsonschema description to reflect new default behavior
- Use backgroundDefault as default, with request-level override capability
- Follows existing pattern similar to SUB_AGENT_TTL configuration

I've re-implemented the SUB_AGENT_BACKGROUND_DEFAULT environment variable feature with the following changes:

  1. Added import for parsing boolean environment variable
  2. Added package-level variable
  3. Read environment variable in function
  4. Updated jsonschema description to reflect the new default behavior
  5. Implemented logic to use as the default, while still allowing request-level override

The implementation follows the existing pattern similar to configuration. The code now:

  • When , background processing becomes the default
  • When or not set, the default remains
  • Request-level parameter can still override the default

Please review again. @mudler
