feat: Claude Code Monitor — lanes, pipelines and a merged workspace
Internal SmartGift build of a Claude Code monitoring dashboard. Lanes: a durable unit of parallel agent work, one per working directory, tracked across session restarts. Managed lanes are git worktrees the dashboard provisions and can reset or remove behind a three-check destroy guard and a counted preflight; adopted lanes are directories you already own and are never destroyable. Pipelines: a lane moves through pipeline stages. A stage the agent declares with evidence renders green; a stage inferred from the tool-event stream renders dashed amber and never counts as done. Detection is forward-only within a 30-minute window, and never writes the declared stage. Workspace: one page at /run with a lane grid, the selected lane's pipeline, and a full Claude console behind a disclosure.

/**
|
||||
* @file tool-views.tsx
|
||||
* @description Per-tool renderers for `tool_input` and `tool_response` fields.
|
||||
* Dispatched from EventDetail when the event's `tool_name` is recognised.
|
||||
* Unknown tools fall back to the caller's generic JSON code view.
|
||||
*
|
||||
* Handled tools:
|
||||
* - Bash / PowerShell → Terminal + TerminalOutput
|
||||
* - Edit / NotebookEdit → Terminal + UnifiedDiff (from old/new + structuredPatch)
|
||||
* - Read → Terminal + LineNumberedCode
|
||||
* - Write → Terminal + LineNumberedCode
|
||||
* - Grep → Terminal + MatchList
|
||||
* - Glob → Terminal + FileList
|
||||
* - WebFetch → Terminal + LineNumberedCode
|
||||
* - Task / Agent → metadata + prompt
|
||||
* - mcp__* → KeyValueCard with known semantic fields promoted
|
||||
* - AskUserQuestion → formatted Q with options
|
||||
* - Any other → returns null (caller falls back to generic JSON)

|
||||
* MODULE_GUIDE — extended in-file reference (comments only; safe to read, never executed)
|
||||
* =============================================================================
|
||||
* **Purpose:** Dashboard module consumed by the React client, MCP tools, or desktop shell depending on deployment mode.
|
||||
*
|
||||
* ## Design constraints
|
||||
* - Local-first: no telemetry leaves the machine unless the user configures webhooks.
|
||||
* - Fail-safe hooks path on the server must never block Claude Code; UI mirrors that
|
||||
* philosophy by degrading gracefully (empty states, stale badges, reconnect loops).
|
||||
* - Destructive flows stay behind explicit confirmation modals and server-side gates.
|
||||
* - Internationalization: user-visible strings belong in i18n JSON, not literals here.
|
||||
*
|
||||
* ## Remote data & SSH
|
||||
* Remote Data Sources let operators aggregate multiple machines. SSH entries describe
|
||||
* how to reach a peer dashboard; the global data scope (`dataScope.ts`) narrows every
|
||||
* scoped GET via `?sources=`. Health checks and import history surface in Settings.
|
||||
*
|
||||
* ## Observability
|
||||
* Prometheus scrapes `GET /api/metrics` (see `monitoring/`). Grafana ships four
|
||||
* provisioned boards (overview, sessions, tools, alerts). Native npm scripts and
|
||||
* Docker Compose profiles are documented in `monitoring/README.md`.
|
||||
*
|
||||
* ## Internal dependencies
|
||||
* - `./primitives`
|
||||
*
|
||||
* ## Public surface
|
||||
* - `ToolInputView` — exported API; see TSDoc on the symbol for behavior.
|
||||
* - `ToolResponseView` — exported API; see TSDoc on the symbol for behavior.
|
||||
*
|
||||
* ## Testing pointers
|
||||
* - Prefer colocated `__tests__` with Vitest + Testing Library for UI.
|
||||
* - Server contract changes require `npm run test:server` and OpenAPI sync.
|
||||
* - MCP edits: `npm run mcp:typecheck` and `npm run mcp:build`.
|
||||
*
|
||||
* ## Related docs
|
||||
* - `ARCHITECTURE.md` — hooks → API → SQLite → WebSocket → UI pipeline.
|
||||
* - `docs/API.md` — REST reference.
|
||||
* - `.claude/skills/file-headers/` — mandatory `@author` header policy.
