Examples

Complete walkthroughs for common plugin patterns:

• Request logger — main-only plugin that logs HTTP traffic to the terminal
• Baseline tests — inject shared post-request assertions into every send
• Trace correlation — seed a trace id via scripts, stamp a header, persist after send
• Production guard — skip sends to production hosts via injected hc.execution.skipRequest()
• Request audit tab — read-only request editor tab
• Solarized theme — theme plugin via registerTheme or JSON import (no JavaScript)
• Import handler — File → Import handler with preview UI
• MCP client server — register a remote MCP endpoint for Harbor's chat agent
• Chat pointers — register @plugin… badges and copy context into the AI sidebar
• AI instructions and turn hooks — append agent instructions and observe chat turns
• Sidebar replacement tree — replace Collections with a custom tree, host context menus, and reorder/move
