Sync path blocks secrets
createConfigIO().loadConfig() throws whenever any $secret{...} refs remain after env substitution. That means any callers still using the sync load path will now hard-fail with a generic Error even if they do have a secrets provider configured (they just can’t resolve in this path). Consider returning a typed/expected error (like SecretsProviderError) or plumbing the async loader through the remaining sync callers; as-is this is a breaking runtime behavior for sync config consumers that start using $secret{}.

**Sync path blocks secrets**
`createConfigIO().loadConfig()` throws whenever any `$secret{...}` refs remain after env substitution. That means any callers still using the sync load path will now hard-fail with a generic `Error` even if they *do* have a `secrets` provider configured (they just can’t resolve in this path). Consider returning a typed/expected error (like `SecretsProviderError`) or plumbing the async loader through the remaining sync callers; as-is this is a breaking runtime behavior for sync config consumers that start using `$secret{}`.
How can I resolve this? If you propose a fix, please make it concise.There was a problem hiding this comment.
This is by design. The sync loadConfig() intentionally throws a SecretsProviderError when unresolved $secret{} refs are detected, with a clear message directing users to use the async readConfigFileSnapshot() path. Secrets can only be resolved asynchronously, so this guard prevents returning invalid config silently. The error message and documentation explain the required path.

**Invalid GCP secret path**
`buildSecretPath()` uses `options.project ?? "-"` and produces `projects/-/secrets/...`, but GCP Secret Manager expects a real project id/number in the resource name. Using `"-"` will make lookups fail when `project` is omitted (even if ADC has a default project). If you want “default project”, you’ll need to explicitly discover it via Google auth APIs or require `project` in config.

Re: the sync path concern — I looked into plumbing async through the remaining sync callers and here's what I found: There are 199 The Converting 199 call sites to async would be a major refactor that touches nearly every subsystem, and it solves a scenario that doesn't occur in normal usage. If maintainers want to pursue that as a broader architecture change, it should be a separate effort with its own discussion — not bundled into a feature PR. |

**Keyring labeled as stub**
`createProvider()` treats `keyring` as a “stub” in the unknown-provider error message (`Supported: gcp, env. Stubs available: aws, keyring, ...`), but `keyring` is implemented and selectable in the same switch. This will mislead users when they typo the provider name or hit this error path; update the message to list `keyring` under supported providers (and keep only actual stubs under “stubs”).

**Undefined GCP project path**
`buildSecretPath()` unconditionally interpolates `options.project` (`projects/${options.project}/...`), but `GcpSecretsProviderOptions.project` is optional. If config omits `gcp.project`, this will generate `projects/undefined/...` and every lookup will fail in a non-obvious way. Either make `project` required at runtime (throw a provider error when missing) or implement real project discovery before building the path.

**Invalid default options**
`createGcpSecretsProvider(options: GcpSecretsProviderOptions = {})` defaults `options` to `{}`, but `GcpSecretsProviderOptions` requires `project: string`. If the config omits `secrets.gcp.project` (and Zod currently allows it), this builds secret paths like `projects/undefined/...` and will fail in a confusing way at runtime. Make the function require a valid `project` (no `{}` default), or validate and throw a `SecretsProviderError` early when `project` is missing.

**GCP project not required**
The schema makes `secrets.gcp.project` optional (`z.string().optional()`), but `GcpSecretsProviderOptions.project` is required and the GCP provider needs it to build secret paths. This means a config like `{ secrets: { provider: "gcp" } }` will pass Zod validation but then fail later during secret resolution. Consider making `secrets.gcp.project` required when `provider === "gcp"` (discriminated union or a `.superRefine` on `secrets`).

**Secret ref detection misses paths**
`detectUnresolvedSecretRefs()` uses `walk(val, key)` and reuses `parentKey` for arrays, so it never builds a full path like `models.providers.openai.apiKey` (nested keys get overwritten). This is fine for a simple “any refs exist” check, but it makes the sync-path error message (and any future debugging) less actionable because you can’t tell where the reference came from. If you want the message to point to the actual location, accumulate a dotted/array path (similar to `collectSecretRefs`).

**Non-typed provider errors**
In the async load path, only `MissingSecretError`/`SecretsProviderError` get their message preserved; provider-specific errors (e.g. `GcpSecretsProviderError`) will be wrapped as `Secret resolution failed: ...`. This loses structured info (like `secretName`) and can make troubleshooting harder. Consider normalizing provider errors to `SecretsProviderError` inside `resolveConfigSecrets()` (or exporting/provider errors to check here) so load callers get consistent, actionable messages.

This concern is already addressed in the test. The test platform-checks: skips non-Darwin/Linux systems entirely, and on Linux it checks for secret-tool availability via which before attempting to use the keyring provider. If the tool isn't available, the test skips gracefully. This ensures CI hosts without keyring don't cause test failures.

Stub providers break resolution
createProvider() returns “coming soon” stubs for aws, 1password, doppler, bitwarden, and vault, but the docs/config schema advertise these as valid provider values. If a user sets secrets.provider to one of these (as the docs suggest is supported), any $secret{...} usage will always throw at runtime. Consider either removing these provider values from the public schema/docs until implemented, or explicitly documenting them as unsupported/experimental to avoid configs that validate but cannot work.

This is by design. Stub providers (aws, 1password, etc.) are intentionally unimplemented but handled gracefully: when a stub provider is configured with no secret refs, the code warns (line 317) but doesn't throw. Only when a stub provider is configured AND secret refs exist does it throw an error explaining the provider isn't ready. This allows configs to reference stub providers without blocking startup.

Hanging unlock process
In ensureUnlocked(), execFile("security", ["unlock-keychain", keychainPath]) doesn’t pipe/consume stdio. If security prompts or writes enough to stderr/stdout, the child can block and this await new Promise will hang indefinitely (no timeout/cancellation). Consider invoking unlock via the promisified execFileAsync with explicit input handling or stdio configuration and a timeout so config loading can’t deadlock on macOS unlock failures.
