The visible feature was only the surface
A support widget can technically load while still conflicting with a site's design, mounting more than once, violating CSP, or failing inside browser-extension surfaces.
The system also had to respect concrete constraints. Integration must use the repository's established SupportKori contract rather than inventing a generic embed. Websites and extensions have different lifecycle, CSP, permission, and iframe boundaries. Remote configuration and publication remain outside an ordinary local integration request.
My role covered agent workflow design and automation engineering, with responsibility for frontend quality, deterministic validation, and portable distribution.
I turned the constraints into boundaries
Host-surface and existing-integration audit; lifecycle-safe trigger and panel integration; CSP, extension, visual, and runtime verification.
Place initialization and cleanup where the host framework can guarantee one active widget instance.
Reuse local tokens and interaction patterns so support feels native to the product.
Validate manifest permissions, CSP, and extension-page behavior instead of assuming website rules apply.
The key decision: Integrate at the lifecycle boundary.
The implementation had to prove the model
I delivered the work across the full path: Codified SupportKori-specific discovery and integration rules. Defined lifecycle and duplicate-mount safeguards. Documented CSP and browser-extension constraints. Added portable packaging and contract tests.
The result is concrete: Agents can audit or integrate SupportKori without replacing an existing valid setup. The widget follows host visual and interaction conventions. Extension-specific security boundaries remain explicit. Verification covers both rendered behavior and integration safety.
The senior engineering lesson was that solving the visible workflow is only half the job. The architecture must also make constraints, failure modes, evidence, and ownership explicit enough for the next change to remain safe.
