Tool usage does not work with custom agents

Tools appear to be configured and sent to the workflow service correctly, but they are not actually executing their intended actions.

Evidence from Testing:

Bug Adder Tool:

1. Configured with "create issue" tool
2. System prompt instructed to create GitLab issues from bug reports
3. Agent responded as if it created an issue
4. No actual issue was created in the project
5. No success/failure events logged despite UI log events being configured

Storyteller Tool:

1. Configured with "create file with contents" tool
2. Agent claimed to create "pineapple under the sea.mmd" file
3. No file was actually created
4. System created empty branches instead (likely related to software development flow bug)

Technical Details:

1. Tools are being sent in the YAML config to workflow service
2. UI log events configured for tool execution success/failure
3. No feedback is being received about tool execution status
