53-57: Verify Babel presets support Node 16+ target.The Babel configuration specifies only
@babel/preset-reactbut omits@babel/preset-env, which is typically needed to transpile modern JavaScript syntax (e.g., optional chaining, nullish coalescing) to Node 16-compatible code. Since the package targets Node >=16, confirm whether modern syntax in the CLI source code requires additional transpilation.If transpilation of modern syntax is needed for Node 16 compatibility, consider adding
@babel/preset-envwith an appropriate Node target:"babel": { "presets": [ + ["@babel/preset-env", { "targets": { "node": "16" } }], "@babel/preset-react" ] }Also add the dependency to

Verify React 19.1.1 compatibility with Ink 4.1.0.
React 19 is a very recent release. Ensure that Ink 4.1.0 has been tested and verified to work with React 19, as terminal UI rendering can be sensitive to React internals.
You may search the web for documentation or recent issues to confirm compatibility:
🌐 Web query:
Is Ink 4.1.0 compatible with React 19?
💡 Result:
No — Ink 4.1.0 is not compatible with React 19. (React 19 support was added later; Ink v6+ requires/supports React 19.) [1][2]
Sources:
- Issue reporting React 19 incompatibility in Ink. [1]
- Ink v6 release notes: “React 19 support” / “Require React 19”. [2]
Ink 4.1.0 is incompatible with React 19.1.1 — update to Ink v6+ or downgrade React.
Ink 4.1.0 does not support React 19; React 19 support was added in Ink v6+. The current dependency configuration will fail at runtime. Either upgrade Ink to v6+ (which requires React 19) or downgrade React to a version compatible with Ink 4.1.0.

apps/cli/watch.js (3)
7-23: Consider graceful shutdown with timeout for child process termination.The current implementation calls
child.kill()without specifying a signal, which defaults to SIGTERM but provides no fallback if the process doesn't exit promptly. Consider implementing a graceful shutdown pattern with a timeout:function startApp() { if (child) { - child.kill(); + child.kill('SIGTERM'); + setTimeout(() => { + if (child && !child.killed) { + child.kill('SIGKILL'); + } + }, 5000); } console.log("\x1b[36m[watch] Starting app...\x1b[0m");This prevents the watcher from hanging if the child process doesn't respond to SIGTERM.
25-38: Add error handler for the file watcher.The watcher lacks error handling for potential file system issues. Add an error handler to prevent silent failures:
watcher.on("change", (path) => { console.log(`\x1b[36m[watch] File changed: ${path}\x1b[0m`); startApp(); }); + +watcher.on("error", (error) => { + console.error(`\x1b[31m[watch] Watcher error: ${error.message}\x1b[0m`); +});
40-45: Use consistent graceful shutdown in SIGINT handler.Apply the same graceful shutdown pattern here as suggested for
startApp():process.on("SIGINT", () => { if (child) { - child.kill(); + child.kill('SIGTERM'); + setTimeout(() => { + if (child && !child.killed) { + child.kill('SIGKILL'); + } + process.exit(0); + }, 5000); + } else { + process.exit(0); } - process.exit(0); });apps/cli/package.json (1)
25-40: Consider updating several outdated development dependencies.Several devDependencies are using older versions that have newer major releases available:
prettier2.8.7 → 3.x is current@babel/cliand@babel/preset-reactare on 7.x but specific versions from 2021-2022While not blocking, updating these would provide better tooling support and bug fixes.

4-59: Component implementation looks solid.The component logic is well-structured:

35-35: The original review comment is incorrect.The latest stable version is eslint-plugin-react-hooks v5.2.0, which works with React 19 for ordinary hooks. React Compiler-specific lint rules are provided only in the v6 series (still in RC), not required for React 19 compatibility. The current version 4.6.0 functions correctly with React 19 and does not require an immediate critical update. Updating to v5.2.0 would be a minor improvement, not a critical fix.

Verify Node.js version requirement for React 19.
The manifest specifies Node >=16, but React 19 is a recent release that may require a newer Node.js version. Node 16 reached end-of-life in September 2023.
Verify the minimum Node.js version required by React 19:
🌐 Web query:
What is the minimum Node.js version required for React 19?
💡 Result:
React itself (React 19) has no strict minimum Node.js requirement — it's a client library; the React 19 upgrade guide doesn't set a Node version. [1]
However, many popular toolchains and frameworks used with React 19 (Vite, Next, Chakra, etc.) require modern Node — commonly Node 20+ (or Node 18.18+/22+ for some tools). So upgrade your Node runtime to at least Node 20 to avoid toolchain/CI issues. [1][2]
Sources:
- React 19 upgrade guide (react.dev). [1]
- Chakra UI (Vite) docs mentioning Node 20.x minimum for Vite-based setups. [2]

Update Node.js engine requirement to >=16.15 minimum.
The specification ">=16" is insufficient because ava 5.2.0 requires Node >=16.15 when using the Node 16 track. This means Node 16.0–16.14 would fail tests. Since Node 16 is EOL (September 2023), consider updating to ">=18" for better alignment with modern toolchains.
🤖 Prompt for AI Agents
In apps/cli/package.json around lines 7–9, the Node engine requirement is ">=16"
which allows unsupported 16.0–16.14 and can break ava 5.2.0; update the
"engines.node" value to ">=16.15" to satisfy ava's minimum Node 16 track
requirement (or set to ">=18" if you prefer to require a more modern LTS), and
ensure package.json formatting remains valid.

In apps/cli/watch.ts around lines 2 to 4, the module imports are not sorted per
project linting rules; reorder the imports into the canonical groups and order
(builtin modules first, then external packages) and sort alphabetically within
each group — e.g., keep "import { spawn, type ChildProcess } from
