Phase 3: Dynamic Workflow Engine - VM sandbox (node:vm) with agent/parallel/pipeline API, Claude Code compatible - Workflow file discovery (.boocode/workflows/*.js + ~/.boocode/workflows/*.js) - Workflow manager with session/chat creation and inference dispatch - Built-in catalog: deep-research, review-code, find-issues - Resumability cache: SHA-256 hash of agent spec, in-memory Map Phase 4: Background Subagents - background-task.ts service: spawn/poll/cancel lifecycle - spawn_subagent, subagent_status, subagent_result tools in ALL_TOOLS Phase 5: Multi-modal + Cache Shape - Multi-modal stub with type defs and hook point in payload.ts - CacheShapeBadge component in trace viewer (colored bar + %)

Dynamic Workflow Engine — Design
Architecture
User writes workflow JS file:
.boocode/workflows/my-flow.js
Workflow Runtime (apps/server)
├── isolated-vm sandbox (or node:vm)
├── API surface: agent(), parallel(), pipeline(), phase(), budget()
├── Tool bridge → BooCode's existing tool set
├── Workflow manager (concurrency, lifecycle)
├── Resumability cache (SHA-256 of agent spec)
└── Catalog (built-in workflows: deep-research, review-code)
Workflow execution:
1. User triggers workflow (slash command or Orchestrator panel)
2. File discovery finds .boocode/workflows/<name>.js
3. Sandbox compiles and executes the script
4. agent() calls go through tool bridge → existing inference pipeline
5. parallel() spawns concurrent agent calls (max 3 default)
6. Results stream via existing WS frames
7. Completed agents cached by hash for resume
API Surface (Claude Code compatible):
agent(prompt, { label?, schema?, model?, capabilities?, max_tool_calls? })
parallel([() => agent(...), () => agent(...)])
pipeline(items, ...stages)
phase(title)
log(message)
budget.total / budget.spent() / budget.remaining()
args
workflow(name, args?) — one level of nesting
Implementation Plan
Phase 1: Core Runtime (this session)
- Sandbox using Node's
vmmodule (no extra deps) agent()function that creates a task and waits for completion- Workflow file discovery
- Basic workflow manager
Phase 2: Advanced Primitives
parallel()with concurrency limitspipeline()streamingbudget()token tracking- Workflow resumability cache
Phase 3: UI + Polish
- Integration with Orchestrator panel
- Built-in workflow catalog
- Workflow editor
- Error recovery
