Overview of Changes

flows pull now records the environment variable names that each flow reads. It analyzes the source after local rewrites and saves the names and completeness result in the manifest. It warns when the selected environment does not define a variable that a flow reads.

A read does not prove that the flow requires the variable. Runtime settings are excluded from these warnings.

Base: chajac/env-key-helpers.

Testing

Naming, lint, format, type, unused-code, and build checks passed. The full test suite passed: 2,520 tests, no failures.

bash scripts/check-naming.sh
bun run typecheck
bun run lint --max-warnings 0
bun run format:check
bun run knip
bun run test
bun run build

Tests cover in-memory staging, inherited path aliases, saved names, completeness, missing-variable warnings, source rewrites, fresh analysis after pull, and older manifests.

Checklist

  • Changes follow the code style of this project
  • Self-review completed
  • Tests added/updated (or not applicable)
  • No breaking changes (or described below)

Walkthrough

qawolf flows pull now statically records environment-variable names used by each flow and stores the results in the manifest. The analysis follows module initialization and reachable calls, and marks flows when reads may be incomplete. Pulls aggregate unset variables, exclude runtime-provided variables, and report warnings in UI and JSON output. Manifest parsing remains compatible with older files. Pull staging also carries cached tags through the new previous-pull helper. Shared file-asset patterns now serve both runtime classification and doctor checks.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

now-unneeded standalone test file.

In `@src/domains/flows/pull/collectFlowEnvVars.ts`:
- Line 22: Update the flow analysis around walkFiles in collectFlowEnvVars to
use the same injected Fs instance used by stageBundle, via an analysis-capable
compiler host if required, so bundleDir is read from the staging filesystem
rather than the host filesystem. Preserve support for in-memory or isolated
filesystems and ensure manifest generation proceeds after staging.

Colocate these tests with their source modules.

bundleEnvVars.test.ts has no matching bundleEnvVars.ts module. It tests buildManifest from bundle.ts and stageBundle from stage.ts. Move the respective cases to bundle.test.ts and stage.test.ts.

As per coding guidelines, “Colocate domain tests next to their source files using the <name>.test.ts naming convention.”
