+# OpenRouter CLI — Existing Structure
+
+This document summarizes the current architecture, modules, and flows of the project as of this commit.
+
+## Overview
+
+- Language/Module: TypeScript (ESM) targeting Node.js >= 18.17.
+- Entry: `src/index.ts` invokes `main()` from `src/main.ts`.
+- CLI: Commander-based commands: `config`, `test`, `ask`, `repl`, `init`.
+- Build: `npm run build` compiles to `dist/**`; runtime binary `bin/openrouter` loads `dist/index.js`.
+- Tests: Vitest in `tests/*.spec.ts`; no network; I/O is mocked where needed.
+
+```
+bin/openrouter ─▶ dist/index.js (built)
+src/index.ts ─▶ src/main.ts ─▶ commands
+                               ├─ src/shared/openrouter.ts  (API, streaming)
+                               ├─ src/shared/format.ts      (markdown→ANSI small)
+                               ├─ src/shared/config.ts      (global/project config, profiles)
+                               ├─ src/shared/env.ts         (defaults, api key helpers)
+                               ├─ src/shared/auth.ts        (ensureApiKey + init fallback)
+                               ├─ src/shared/init.ts        (interactive wizard)
+                               └─ src/repl.ts               (interactive chat)
+```
+
+## Commands and Control Flow
+
+- `config`
+  - Shows or updates API key. Profile-aware via `--profile` and `--list`.
+  - Domain/model edits are intentionally kept out of `config` (managed via `init`).
+
+- `test`
+  - Verifies connectivity via `GET /models` using `testConnection()`.
+  - Resolves effective config and optionally triggers `init` when missing keys and running in TTY.
+
+- `ask`
+  - One-shot completion via `POST /chat/completions`.
+  - Streaming default; `--no-stream` path renders full answer then prints styled header/footer.
+  - Output format: `auto|plain|md` mapped by `src/shared/format.ts`.
+
+- `repl`
+  - Interactive session; supports `/model`, `/system`, `/format`, `/stream` commands.
+  - Streams by default; non-stream reuses `askOnce` + renderer.
+
+- `init`
+  - Interactive wizard to pick provider/domain/model and optionally persist API key.
+  - Tests connection before saving; writes to base config or a named profile.
+
+## Configuration & Precedence
+
+- Global file: `~/.config/openrouter-cli/config.json` (chmod `600` best-effort).
+- Profiles: stored under `profiles` inside the same JSON file.
+- Project overrides: `.openrouterrc(.json|.yaml|.yml)` in CWD.
+- Precedence for `resolveConfig(profile?)`: project RC > named profile > global base.
+- API key lookup: `OPENROUTER_API_KEY` or `OPENAI_API_KEY` envs take priority over persisted key.
+- `maskKey()` redacts logged keys; code avoids printing secrets.
+
+## Networking Layer (`src/shared/openrouter.ts`)
+
+- `testConnection({ domain, apiKey })`: GET `/models`, returns JSON or throws on non-OK with body.
+- `askOnce(opts, messages)`: POST `/chat/completions`, `stream:false`; returns assistant text.
+- `streamChat(opts, messages)`: same endpoint with `stream:true`; reads SSE and writes deltas to stdout.
+- `joinUrl(base, path)`: safe URL join preserving base path.
+- `safeJson(res)`: tries JSON, falls back to text.
+
+Notes:
+- Request-level timeouts and normalized error mapping are not yet implemented (planned in upcoming tasks).
+
+## Rendering & UI
+
+- Markdown renderer: `src/shared/format.ts`
+  - Minimal ANSI formatting for headings, lists, inline code; streaming path stays plain for responsiveness.
+- Theming/UI: `src/shared/ui.ts`
+  - Color detection: honors `NO_COLOR` and only colors when `process.stdout.isTTY` is true.
+  - Palette: accent, ok/warn/err, dim, bold (chalk-backed but safe without colors).
+  - Components: banner, examples box (help), non-stream answer header/footer, REPL prompt and tips box.
+  - Commander help: `attachStyledHelp(program)` injects banner/examples via `addHelpText('beforeAll', ...)`.
+
+## Security
+
+- API keys are never logged; persisted config is written with `chmod 600` when possible.
+- Prefer environment variables for ephemeral keys; `openrouter config --api-key` persists only when desired.
+
+## Testing
+
+- Vitest specs under `tests/` cover:
+  - Config precedence and YAML rc handling.
+  - URL join behavior.
+  - Streaming SSE parsing and non-stream error propagation.
+  - CLI help shape and basic styled help presence.
+  - Redaction behaviors and minimal UI blocks.
+
+## Build, Lint, and Scripts
+
+- Build: `npm run build` → `dist/**`
+- Dev (TS directly): `npm run dev -- <cmd>` (uses ts-node ESM loader).
+- Tests: `npm test`; coverage: `npm run test:coverage`.
+- Lint: `npm run lint` (flat config `eslint.config.js`).
+- Packaging: `prepack` builds and runs `scripts/prepack.mjs`.
+
+## Dependencies (runtime)
+
+- `commander` (CLI), `js-yaml` (project rc YAML), `chalk` and `boxen` (UI), `cli-table3`, `ora` (available for future spinners/tables).
+
+## Open Items / Upcoming Work
+
+- Timeouts and normalized error handling for network requests.
+- Non-interactive flags for `init` (provider/domain/model/api-key/profile) as part of CI flows.
+- Documentation polish (README examples, REPL transcript, small screencast).
+- Optional CI packaging and coverage upload.
