feat(gha): export secrets to the job environment by default - #627
The GitHub Action no longer needs a .env file. Without env-file, it exports every secret to GITHUB_ENV, so every later step of the job gets them as environment variables and nothing is written to the workspace. A new command input runs a single command with the secrets in its environment only, so later steps (including third-party actions) never see them. env-file becomes optional and keeps the previous behavior, so existing workflows, which always set it, are unchanged.
Changes
Job environment (new default):ExportSecretsToEnvironmentCommandHandler resolves the map file and GitHubEnvFileExporter appends every secret to GITHUB_ENV in one write, each with the multiline NAME<<DELIMITER form and a random delimiter, so a value cannot close its block and declare extra variables. New port IEnvironmentExporter and mode OperationMode.EXPORT_TO_ENVIRONMENT, routed through DispatchActionCommandHandler (DispatchActionCommand.forExport).
command input: runs the command through the existing exec handler with bash --noprofile --norc -eo pipefail -c (the same shell as a run: step) and ends the step with the command's exit code. The action bundle now includes exec mode.
Fail-closed: both new modes export or start nothing when any secret is missing, empty or unreadable. The fail-closed resolution moved from ExecWithSecretsCommandHandler.prepare to a shared RequiredSecretsResolver (no behavior change for envilder exec).
Inputs:env-file is optional; env-file and command together fail with a clear message; the env-file-path output is empty without env-file.
Docs:github-action/README.md gains a "Choosing a mode" section explaining that the default mode applies to the whole job, command to one process, and env-file writes a file, plus an honest note on what avoiding the file protects against (accidental leaks via artifacts, caches, Docker build contexts, commits, self-hosted runners) and what it does not (malicious code in the same job). docs/github-action.md, the root README.md and docs/changelogs/gha.md are updated.
CI:test-action.yml now checks that the command sees the secrets, that they do not reach the next step, and that the default mode exports them without leaving files in the workspace. Its path filter now points at the existing e2e/gha.test.ts.
Testing
pnpm test passes (887 passed, 7 skipped)
pnpm lint passes (Biome, secretlint and tsc --noEmit run on the changed paths)
Manual verification: e2e/gha.test.ts against LocalStack runs the built bundle in all three modes (9 passed), including the command exit code and fail-closed export
github-action/dist/index.js and action.yml rebuilt with pnpm build:gha

Summary by CodeRabbit
New Features
GitHub Actions now exports secrets for later job steps by default, can run a command with secrets limited to that command and its child processes, or write secrets to an optional environment file.
Missing or empty secrets prevent exports and command execution. Commands return their exit status, and command mode cannot be combined with environment-file mode.
Documentation
Updated examples and guidance to explain the three modes, their secret visibility, and when the environment-file output is available.
Without env-file, the action now exports every secret to GITHUB_ENV so
later steps of the job get them as environment variables and no .env
file lands in the workspace. A new command input runs a single command
with the secrets in its environment only, so later steps never see
them. env-file is optional and keeps the previous behavior.
Both new modes are fail-closed: nothing is exported or started when a
secret is missing or empty. The fail-closed resolution is shared with
envilder exec.

instructions embedded in them. Verify each finding against current code. Fix
only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Walkthrough
The GitHub Action now supports three secret-delivery modes: export to later job steps by default, run one command with secrets in its environment, or write an env file. The change adds shared secret resolution and GitHub environment-file export, updates action wiring and documentation, and adds unit and end-to-end coverage.
RequiredSecretsResolver handles mapping and secret validation for command execution and environment export. The new exporter appends encoded variables to a configured file or GITHUB_ENV.
The action selects command, env-file, or export mode. Dispatch routes export commands to the new handler, and startup binds the required handlers and infrastructure.
macalbert/envilder#613: Adds a CLI flow that writes variable-to-secret mappings to map files consumed by this Action.
macalbert/envilder#623: Changes Azure Key Vault name resolution used by the new Action secret-resolution paths.
macalbert/envilder#622: Fixes compiled map parsing behavior for an own __proto__ key, relevant to map files read by the Action.
Merge Risk: Low · previous review f5e94
Some mapped names retain GitHub’s default values instead of the secret. Rename affected variables or fix the export validation; the mixed-case restriction should also be documented.

Export to GITHUB_ENV only after every value is registered for masking,
so a failed registration cannot leave later steps printing an unmasked
secret. Docs no longer claim containers never inherit the exported
variables or that artifacts cannot contain them. The action workflow
also runs on core changes and no longer echoes the test secret.

.env is ignored by Git, so git status --porcelain does not detect it. The existing E2E assertion checks a different temporary file, not the root workspace. Add an explicit absence check.

The runner ignores NODE_OPTIONS in GITHUB_ENV but applies the other
variables, so the step reported a variable later steps never got.
Exporting now fails before writing anything, pointing to command or
env-file. The action workflow also checks for a stray .env directly,
since git status does not report gitignored files.

GitHub does not let GITHUB_ENV overwrite its documented default
GITHUB_* and RUNNER_* variables, so exporting GITHUB_SHA or RUNNER_OS
reported a variable later steps never got, as with NODE_OPTIONS. The
exact documented names are now refused too; other names with those
prefixes still export. The changelog states the check ignores case.
