From feafd4bb5d23a4395c0083013a94ecabef17e5bc Mon Sep 17 00:00:00 2001 From: M09Ic Date: Sat, 18 Jul 2026 08:37:28 -0700 Subject: [PATCH 01/40] refactor: decouple agent, tool, and web layers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce core/tool (shared tool contracts) and core/node (shared web connectivity) to break cross-package dependencies: - core/tool: ToolDefinition, Result, Executor, Tool interfaces with zero project dependencies. Renamed from core/toolapi with simplified names (tool.Definition, tool.Result, tool.Executor, tool.Tool). - core/node: shared WebSocket connectivity extracted from pkg/webagent (1400→612 lines). Defines ConnectConfig + ChatHandler interface so both runner and agent connect to web via the same node.Connect(). - pkg/agent no longer imports pkg/commands (Config.Tools is now tool.Executor interface; LoopCommand accepts injected io.Writer). - pkg/commands no longer imports pkg/agent/provider (types come from core/tool via aliases; pkg/tools/* need zero changes). - cmd/runner no longer imports pkg/webagent (uses core/node directly). - core/config no longer imports pkg/webproto (FetchRemoteConfig moved to pkg/webagent where the web dependency belongs). - pkg/agent/probe no longer imports pkg/webproto (uses own ProbeConfig; pkg/web converts DistributeConfig at the boundary).

Subject: [PATCH 02/40] feat: switch to AOP event protocol + unify chat with
 cyber-ui viewer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Agent Output Protocol (AOP):
- New pkg/aop/ package: Go types, agent.Event→AOP conversion, JSONL writer
- All event serialization paths switched to AOP v1 format
- Delete pkg/agent/event_json.go (old MarshalJSON no longer needed)
- Web hub forwardAgentEvent consumes AOP events directly
- Harness/timeline adapted to parse AOP JSONL

Chat unification:
- Local viewer component forks deleted (6 files)
- src/viewer/index.ts now re-exports from @cyber/viewer
- All chat rendering uses upstream viewer ChatPanel with variant/slot system
- aiscan-specific features (scan cards, eval badge, agent_joined) via extension registry
