Codex CLI helps each sandbox ranges and approval modes. These are likely to overlap; I’ve solely examined approval modes. Basically, the advice is to make use of auto mode if the folder you’re working in has a git repository, and to make use of read-only mode if it doesn’t.
▌ Choose Approval Mode
▌
▌ 1. Learn Solely Codex can learn recordsdata and reply questions. Codex requires
▌ approval to make edits, run instructions, or entry community
▌ > 2. Auto (present) Codex can learn recordsdata, make edits, and run instructions in
▌ the workspace. Codex requires approval to work exterior the
▌ workspace or entry community
▌ 3. Full Entry Codex can learn recordsdata, make edits, and run instructions with
▌ community entry, with out approval. Train warning

> Overview
- Cline markets itself as a human-in-the-loop agentic coding companion for
VSCode, combining editor, terminal, browser, and MCP tooling (README.md:1).
- Extension metadata, activation triggers, command registrations, and
market packaging stay in package deal.json:1, exhibiting it targets VSCode 1.84+
and ships below Apache-2.0.
- The core structure is documented as “extension → webview → controller →
process,” providing you with the top-level psychological mannequin for a way work strikes by the
system (src/core/README.md:1).
Runtime Circulate
- Activation bootstraps the host bridge, sidebar webview, diff suppliers,
and command palette entries earlier than handing management to the controller (src/
extension.ts:1).
- The controller handles workspace discovery, auth, telemetry, MCP lifecycle,
and state sync between the extension host and webview (src/core/controller/
index.ts:1).
- Job orchestration manages API calls, context home windows, software invocations,
checkpoints, and multi-step plans whereas streaming partial responses again to
the UI (src/core/process/index.ts:1).
- Protobuf contracts outline the bi-directional messages (asks, says, software
calls, UI instructions), letting the host, webview, and exterior shoppers discuss over
gRPC (proto/cline/ui.proto:1).
AI & Software Integrations
- A wealthy supplier layer wraps dozens of mannequin backends (OpenRouter, Anthropic,
Collectively, Bedrock, and many others.) with retryable streaming assist and per-model tuning
(src/core/api/suppliers/openrouter.ts:1 and friends).
- MCP Hub hundreds user-configured servers, watches configs, and proxies software/
useful resource calls so Cline can prolong itself with exterior capabilities (src/
companies/mcp/McpHub.ts:1).
- TerminalManager reuses VSCode terminals, streams shell output by way of the brand new
shell-integration hooks, and captures outcomes for the agent’s reasoning (src/
integrations/terminal/TerminalManager.ts:1).
- BrowserSession can launch or connect to Chromium and headless browsers to
automate net flows, accumulate screenshots, and floor console logs when duties
require it (src/companies/browser/BrowserSession.ts:1).
Frontend Webview
- The webview UI is a Vite/React app with Tailwind, Storybook, and Vitest,
bundled alongside the extension and constructed by way of devoted scripts (webview-
ui/package deal.json:1).
- Suppliers wrap context, telemetry, and gRPC shoppers earlier than rendering,
enabling server-driven state hydration and announcement dealing with within the
sidebar (webview-ui/src/App.tsx:1).
- ChatView composes messaging panes, token/price analytics, fast actions, and
slash-command tooling, powered by protobuf-backed gRPC shoppers shared with the
host (webview-ui/src/elements/chat/ChatView.tsx:1).
Testing & Ops
- A CLI-based testing platform spins up gRPC adapters and harnesses to
replay scripted conversations towards the standalone server or the extension
(testing-platform/README.md:1).
- Recorded session fixtures train chat flows, slash
instructions, and multi-root workspaces, enabling regression
checks with out re-running full UI checks (checks/specs/
grpc_recorded_session_chat___can_send_messages_and_switch_between_modes.json:1
).
- The evals suite benchmarks Cline throughout standardized coding duties, diff-edit
challenges, and mannequin comparisons, with a CLI that toggles the extension into
take a look at mode on demand (evals/README.md:1).
Subsequent steps:
1. Set up dependencies with npm run set up:all (root + webview) and generate
protobuf stubs by way of npm run protos.
2. For native growth, run npm run watch (host) in a single terminal and npm run
dev:webview in one other to iterate on the extension and sidebar UI collectively.
