Anything a loader returns ends up readable in the\nbrowser. The Vite plugin also strips server-only exports from route files, but\nit cannot save you from a value that flows into the return.</p>\n<p>Prerequisites: <code>pracht inspect</code> requires a vite config that registers the\npracht plugin; the env-safety report under <code>dist/client/_pracht/</code> requires a\nprior <code>pracht build</code>. If the pracht MCP server is registered (see\n<a href=\"https://pracht.resynapse.dev/docs/coding-agents#the-authoring-mcp-server\">https://pracht.resynapse.dev/docs/coding-agents#the-authoring-mcp-server</a>), prefer its tools (<code>inspect_routes</code>, <code>inspect_api</code>,\n<code>inspect_build</code>, <code>doctor</code>, <code>verify</code>) over shelling out.</p>\n<h2>Step 0: Run the native env safety check</h2>\n<p>Pracht has built-in env leak detection (see <a href=\"https://pracht.resynapse.dev/docs/env#client-leak-detection\">https://pracht.resynapse.dev/docs/env#client-leak-detection</a>):</p>\n<ul>\n<li><code>pracht build</code> fails when a client chunk references a non-public env var\n(anything not <code>PRACHT_PUBLIC_</code>-prefixed and not a Vite built-in),\nnaming the variable, chunk, and likely source module.</li>\n<li><code>pracht verify</code> (and <code>pracht doctor</code>) check the build-time env-safety report\nand re-run the literal chunk scan against an existing <code>dist/client</code> output.</li>\n<li>Client-side imports of <code>@pracht/core/env/server</code> (<code>serverEnv</code>) fail the build.</li>\n</ul>\n<p>Run <code>pracht verify</code> or <code>pracht doctor</code> (or a build) first and fold the\nfindings into the report.\nCheck <code>vite.config.*</code> for <code>envSafety: { allow: [...] }</code> / <code>envSafety: false</code> —\nevery allowlisted name and a disabled check are findings to review, since they\nbypass the native gate. The native check detects <em>references</em>, not values, so\nthe dataflow steps below are still required.</p>\n<h2>Step 1: Identify \"secret-shaped\" identifiers</h2>\n<p>Build a regex of variable names treated as sensitive:</p>\n<pre><code>SECRET|TOKEN|API[_-]?KEY|PRIVATE[_-]?KEY|PASSWORD|PASSPHRASE|SESSION[_-]?SECRET|JWT[_-]?SECRET|WEBHOOK[_-]?SECRET|DATABASE[_-]?URL|DB[_-]?URL|CONNECTION[_-]?STRING|CLIENT[_-]?SECRET|REFRESH[_-]?TOKEN\n</code></pre>\n<p>Also flag any direct <code>process.env.X</code> or <code>context.env.X</code> reference where <code>X</code>\nmatches the above.</p>\n<h2>Step 2: Server → client flow analysis</h2>\n<p>For every route file, trace whether a sensitive value reaches the loader's\nreturn value. Steps:</p>\n<ol>\n<li>Run <code>pracht inspect routes --json</code> to enumerate routes.</li>\n<li>For each route, read the loader.</li>\n<li>Build a small dataflow trace from sensitive identifiers (and <code>process.env.*</code>\n/ <code>context.env.*</code> reads) to the <code>return</code> statement(s).</li>\n<li>Flag any spread (<code>...row</code>, <code>...user</code>, <code>...env</code>) that originates from a\nsource containing secrets.</li>\n<li>Flag direct returns of objects that name sensitive keys.</li>\n</ol>\n<p>This is heuristic — favor over-flagging over silent leaks. Note false-positive\nrisk in the report.</p>\n<h2>Step 3: Module import boundaries</h2>\n<p>Grep client-rendered files (route components, shells, the app root registered\nas <code>defineApp({ root })</code> or <code>pages/_root.tsx</code>, anything imported from them) for\nimports of:</p>\n<ul>\n<li><code>node:*</code> builtins</li>\n<li><code>@pracht/adapter-*</code></li>\n<li>Local <code>src/server/**</code> modules</li>\n<li>Modules whose top level reads <code>process.env.*</code></li>\n</ul>\n<p>The Vite plugin strips the server-only exports <code>loader</code>, <code>head</code>, <code>headers</code>,\n<code>getStaticPaths</code>, and <code>markdown</code> from route files when serving the client\nquery (<code>middleware</code> is not a route-file export — middleware lives in the\nmanifest); see <a href=\"https://pracht.resynapse.dev/docs/env#client-leak-detection\">https://pracht.resynapse.dev/docs/env#client-leak-detection</a>. But a component that imports <code>../server/db</code> will still\npull <code>db</code> into the client bundle. Flag those imports. The app root's browser\ncopy loses only <code>dehydrate</code> and the imports nothing else uses; <code>setup()</code>,\n<code>Root</code>, <code>hydrate()</code>, and everything they import ship. A <code>dehydrate</code> bound in\nthe same destructuring as those (<code>export const { setup, Root, dehydrate, hydrate } = createRoot(…)</code>) or reached through <code>export *</code> ships with them, so\nflag a server-only value passed into that call. A root whose other code calls\nor re-exports <code>dehydrate</code> ships whole; flag its server-only imports too.</p>\n<h2>Step 4: Hidden surfaces</h2>\n<p>Check for accidental exposure outside loaders:</p>\n<ul>\n<li>The app root's <code>dehydrate()</code> snapshot: it lands in <code>pracht-state</code> as <code>root</code>\nand in every route-state response, like loader data. For <code>@pracht/query</code>\nthat is every successful query cached during the request, so flag a\n<code>queryFn</code> or <code>setQueryData</code> in a loader that caches a secret-bearing value.</li>\n<li><code>head()</code> returns: rare, but a <code>meta</code> value containing a token leaks into HTML.</li>\n<li><code>headers()</code> returns: flag values that look like secrets. For SSG/ISG pages,\ndocument headers enter <code>dist/server/headers-manifest.json</code>; every serverful\nbuild currently also copies that manifest to public\n<code>dist/client/_pracht/headers.json</code> (only Cloudflare reads it there). A pure\nstatic export omits the client copy but may mirror the server manifest into\nhost configuration. This skill owns secret VALUES in headers; header policy\n(CSP, HSTS, weakened defaults) is owned by <code>audit-headers</code> — cross-reference\nit.</li>\n<li><code>&lt;Form&gt;</code> <code>action</code> URLs containing tokens in the query string.</li>\n<li><code>prefetchRouteState(url)</code> calls with sensitive query params.</li>\n<li>Inline <code>&lt;script&gt;</code> content emitted from custom shells.</li>\n</ul>\n<h2>Step 5: <code>.env</code> discipline</h2>\n<ul>\n<li>Confirm <code>.env*</code> is in <code>.gitignore</code>.</li>\n<li>Confirm generated starters preserve <code>!.env.example</code> if they ignore <code>.env*</code>.</li>\n<li>Grep tracked files for likely committed secrets (long random strings near\nidentifier names from step 1).</li>\n<li>Confirm client-side env access goes through <code>publicEnv</code> (from\n<code>@pracht/core</code>) or <code>import.meta.env.PRACHT_PUBLIC_*</code>; <code>VITE_*</code> values are\nstill exposed by Vite compatibility wiring, but Pracht does not treat them as\nintentionally public, so flag client-side <code>VITE_*</code> references unless they are\nexplicitly allowlisted and reviewed. Warn loudly if a public env name has a\nsecret-shaped name.</li>\n<li>Flag any client-side read of <code>import.meta.env</code> that is not a single-key\naccess — a bare reference, destructuring, a spread, or bracket access such as\n<code>const env = import.meta.env</code> or <code>import.meta.env[\"MODE\"]</code>. Vite replaces\nthose with an object literal holding <strong>every</strong> exposed variable, so the\n<code>VITE_*</code> values land in the bundle with no accessor text left for a\nname-based grep to find. Use <code>publicEnv</code> to enumerate public values.</li>\n<li>Confirm server-side env access uses <code>serverEnv</code> (from\n<code>@pracht/core/env/server</code>) or <code>context.env</code> rather than ad-hoc globals.</li>\n</ul>\n<h2>Step 6: Report</h2>\n<table>\n<thead>\n<tr>\n<th>File:Line</th>\n<th>Identifier / source</th>\n<th>Sink (loader return / client import / etc.)</th>\n<th>Severity</th>\n</tr>\n</thead>\n</table>\n<p>Severities:</p>\n<ul>\n<li><code>error</code> — direct flow from <code>process.env.SECRET_*</code> / <code>serverEnv.SECRET_*</code> to\nloader return.</li>\n<li><code>error</code> — <code>PRACHT_PUBLIC_*_SECRET</code> style client-public or allowlisted <code>VITE_*_SECRET</code>\nsecret-shaped name.</li>\n<li><code>error</code> — <code>envSafety: false</code> or an allowlisted name that looks secret-shaped.</li>\n<li><code>warn</code> — spread of a row that may contain secret columns.</li>\n<li><code>warn</code> — client component imports a module that reads <code>process.env</code>.</li>\n<li><code>info</code> — header value that looks like a token.</li>\n</ul>\n<h2>Rules</h2>\n<ol>\n<li>Heuristic-first; document false-positive risk per finding.</li>\n<li>Recommend an explicit allowlist projection (<code>{ id, name, email }</code>) over\nblocklist filtering.</li>\n<li>For Cloudflare apps, secrets live in <code>context.env</code> — same risk profile as\n<code>process.env</code>.
