218-233: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winPreserve the original error and do not attribute import failures to the registry.
The catch block wraps every failure with the offline/registry hint. The
await import(...)on Line 219 runs inside the sametry, so a syntax error or a top-level throw inside the component module reports as an acquisition problem. The rewrappedErroralso drops the original stack andcause, which makes acquisition failures harder to diagnose.Attach
cause, and add the registry hint only for acquisition failures.♻️ Proposed refactor
- const entry = await resolvePackageEntry(packageDir); - const module: Record<string, unknown> = await import( - pathToFileURL(entry).href - ); - return { module, packageName, normalizedFlow, packageDir, installDir }; - } catch (error) { - await fs.remove(installDir).catch(() => undefined); - const message = error instanceof Error ? error.message : String(error); - throw new Error( - `Failed to load ${packageName} for ${kind}.${id}: ${message}\n` + - `Setup fetches the flow's pinned package from the npm registry, ` + - `sharing the bundle cache. If you are offline, run once online to ` + - `warm the cache (exact version pins stay cached), or point ` + - `config.bundle.packages["${packageName}"].path at a local built package.`, - ); - } + let acquired = true; + try { + const entry = await resolvePackageEntry(packageDir); + const module: Record<string, unknown> = await import( + pathToFileURL(entry).href + ); + return { module, packageName, normalizedFlow, packageDir, installDir }; + } catch (error) { + acquired = false; + throw error; + } finally { + if (!acquired) await fs.remove(installDir).catch(() => undefined); + } + } catch (error) { + await fs.remove(installDir).catch(() => undefined); + const message = error instanceof Error ? error.message : String(error); + throw new Error( + `Failed to load ${packageName} for ${kind}.${id}: ${message}\n` + + `Setup fetches the flow's pinned package from the npm registry, ` + + `sharing the bundle cache.

so it is skipped when the npm registry is unavailable, while preserving
execution when the registry can be reached. Update the test around
loadStepPackage and its pinned `@walkeros/web-destination-api` download, using the
suite’s existing network or registry availability mechanism if one exists.
In `@packages/cli/src/core/step-packages.ts`:
- Around line 189-223: Update the package reconciliation logic around
originalVersions, bundlePinnedVersion, and inlineSeen so a configured
packages[name].path is treated as an authoritative local pin; skip conflicting
inline-version validation and retain the path-based package selection, allowing
setup and bundling to proceed without rejecting irrelevant inline versions.
In `@skills/walkeros-using-cli/SKILL.md`:
- Around line 364-368: Update the setup command usage line to include the
supported --verbose and --silent flags alongside the existing options, matching
the fields accepted by SetupCommandOptions.
In `@website/docs/apps/cli.mdx`:
- Around line 733-736: Update the “No version drift” statement to qualify that
setup and bundle use the same version only within a single execution or when the
package specification resolves identically; do not promise stability across
separate executions for latest, ranges, or changing local path contents. Keep
the existing documentation for exact version pins unchanged.
In `@website/docs/destinations/web/gtag/gtm.mdx`:
- Around line 57-60: Update the gtag GTM documentation around initGTM to remove
the claim that walkerOS “touches nothing else” when loadScript is unset; state
that it still creates the configured data layer when absent, while continuing to
describe that it does not load the GTM script.
In `@website/docs/sources/envelope.mdx`:
- Line 51: Update the prose in the async POST explanation to hyphenate the
compound modifier as “per-index outcomes.”
In `@website/docs/sources/server/express.mdx`:
- Around line 180-186: Update the status table so pipeline-declared invalid 400
responses and pipeline-failure 500 responses are explicitly limited to
synchronous POST requests, while retaining the unparseable-JSON 400 behavior
generally. Qualify the GET 200 response description to indicate it also covers
unexpected server failures handled by the GIF fallback.

Limit delivery-result status codes to synchronous POST.
Line 181 and Line 186 describe pipeline-invalid and pipeline-failure responses for all synchronous requests. In packages/server/sources/express/src/index.ts Lines 243-248, GET ignores a resolved failed PushResult and sends the GIF fallback. Only a thrown or rejected GET push reaches the outer 500 handler before a response is sent.
Document 400 and delivery-result 500 behavior as synchronous POST behavior. Qualify the later GET 200 statement for unexpected server failures.

Register the source-browser server in the plugin manifest.
The package READMEs and website documentation state that walkeros@elbwalker installs both MCP servers. The current manifest declares only walkeros-flow; it does not start @walkeros/mcp-source-browser. (raw.githubusercontent.com) Add the missing server entry, or remove the claim from the documentation. Otherwise, the documented plugin installation does not expose the source-browser tools.

🧩 Analysis chain
🌐 Web query:
For the Node.js version declared by this repository, does the ESM PACKAGE_RESOLVE algorithm resolve a bare builtin package name such as asserttonode:assert before searching node_modules?
💡 Result:
Yes, the ESM PACKAGE_RESOLVE algorithm resolves a bare builtin package name (such as "assert") to a "node:" protocol string (e.g., "node:assert") before it considers searching node_modules or performing other package resolution steps [1][2][3][4]. According to the official Node.js ESM resolution algorithm, the PACKAGE_RESOLVE function begins with the following check: 1. Let packageName be undefined. 2. If packageSpecifier is an empty string, then throw an Invalid Module Specifier error. 3. If packageSpecifier is a Node.js builtin module name, then return the string "node:" concatenated with packageSpecifier [1][4]. Because this check occurs at the very beginning of the PACKAGE_RESOLVE algorithm, it prevents builtin modules from being shadowed by packages installed in node_modules [1][2][4]. The subsequent logic—which handles package self-resolution and the search through node_modules—is only reached if the specifier is not a builtin [1][4].

Handle Node builtin package names before calling fileURLToPath().
When packageName is an npm package named assert, events, or another Node builtin, import.meta.resolve(packageName) returns a node: URL. fileURLToPath() rejects that URL with ERR_INVALID_URL_SCHEME, so setup fails after acquisition. Resolve the extracted package through an alias or a directory-based resolver that preserves exports semantics, and add a regression test for assert.

For the repository's declared Node.js version, which TypeScript file extensions can dynamic import load or reject: .ts, .tsx, .mts, and .cts?
💡 Result:
For Node.js's built-in TypeScript support (introduced to natively execute TypeScript files via type stripping), the dynamic import mechanism rejects the.tsx file extension [1][2][3]. Specifically, within the Node.js documentation for TypeScript modules, it is explicitly stated that.tsx files are unsupported [1][2]. Conversely, the extensions.ts,.mts, and.cts are supported for native execution and dynamic loading within the Node.js TypeScript module system [1][2]. Key details regarding these extensions in Node.js:.ts: The module system (ESM or CommonJS) is determined in the same manner as.js files, typically based on the nearest parent package.json "type" field [1][2]..mts: Always executed as an ES module [1][2]..cts: Always executed as a CommonJS module [1][2]. Because Node.js requires explicit file extensions in import specifiers when using native TypeScript support, you must include the extension (e.g., import('./file.ts')) for the dynamic import to resolve correctly [1][2]. Failure to use a supported extension or omitting the extension entirely will result in a runtime error [1][2].

Node.js 20 native TypeScript support dynamic import .ts .mts .cts .tsx
💡 Result:
Node.js 20 does not include native support for executing TypeScript files (.ts,.mts,.cts,.tsx) [1][2]. The native "type stripping" feature—which allows Node.js to execute TypeScript files directly by removing type annotations—was introduced in later versions of Node.js [3][4]. In current versions that support this feature (e.g., Node.js 22.18.0 and later, or via the --experimental-strip-types flag in slightly earlier versions), the following limitations apply: 1. Supported Extensions: Only.ts,.mts, and.cts files are supported for type stripping [4][5]. 2. Unsupported Extensions:.tsx files are not supported natively [4][5]. 3. Execution Behavior: Native support is limited to "type stripping," meaning Node.js simply removes type-only syntax (e.g., interfaces, type annotations) and runs the remaining JavaScript [3][6]. It does not perform type checking or transform TypeScript-specific features that require code generation (such as enums or namespaces), unless specific experimental flags are used [3][7][4]. 4. Dynamic Import: While dynamic import is fully supported in Node.js for loading modules, native type stripping does not perform the transpilation required to resolve TypeScript-specific import paths or extensions if they are not standard [6][8]. For full TypeScript support in Node.js 20, including.tsx files, complete language feature support, and integration with tsconfig.json, you must use a third-party transpiler or runner, such as tsx, ts-node, or by running the TypeScript compiler (tsc) manually to emit JavaScript before execution [3][6].

In ECMAScript, what do Number("not-a-number")and0 < NaN evaluate to?
💡 Result:
In ECMAScript, the expressions evaluate as follows: Number("not-a-number") evaluates to NaN [1][2]. When the Number function is used to convert a value that cannot be parsed as a valid number, it returns the special "Not-a-Number" value, NaN [1][3]. 0 < NaN evaluates to false [4]. In ECMAScript, the relational operator (<) uses the IsLessThan abstract operation [5][6]. When performing a comparison involving NaN, the IsLessThan operation returns undefined [5][6]. According to the specification for the relational expression, if the result of the comparison is undefined, the expression evaluates to false [4].
