Summary

  • prevent commit-echo init from reusing a stored API key after switching providers
  • clear persisted apiKey whenever config set provider changes the provider
  • keep the newly selected provider's environment key available after a switch
  • add regression coverage for both paths

Closes #312

Review in cubic

Summary by CodeRabbit

  • Bug Fixes
    • Provider settings now preserve or clear saved connection details more consistently when switching between providers.
    • API keys are now resolved with clearer precedence, including support for a general environment override and trimming extra whitespace.
    • During setup, the app now better recognizes a saved API key only when it matches the selected provider.

📝 Walkthrough

Walkthrough

Provider changes now clear stored API keys. Initialization reuses a stored key only when its provider matches the selected provider, and resolves keys from the generic or provider-specific environment variable when available.

Changes

Provider credential handling

Layer / File(s) Summary
Provider-aware initialization key selection
src/commands/init.ts, tests/init-api-key-prompt.test.mjs
Initialization trims candidate keys and checks them in this order: COMMIT_ECHO_API_KEY, a provider-matching stored key, then the provider-specific environment variable. Tests cover matching, mismatched, and invalid stored keys, plus environment-variable precedence.
Provider configuration changes
src/commands/config.ts, tests/config-command.test.mjs
Changing providers clears the stored API key. Switching to a built-in provider also clears the base URL. Tests verify that key resolution uses the selected provider’s environment variable.

Changing custom endpoints can send the previous endpoint’s secret to the new one. Blank key values can also prevent a valid key from being selected. Both need correction before merging.

A rabbit checks each key with care,
And trims the spaces hiding there.
A matching provider keeps its own,
While switched keys find a new env home.
The config clears the stale old trail,
Then hops ahead, secure and hale.

Shadow auto-approve: would require human review. Clears the persisted API key on provider switch and scopes init key reuse to the matching provider, with tests. This alters credential persistence and env-override precedence, so a human should review the secret-handling tradeoff.

In `@src/commands/init.ts`:
- Around line 50-52: Update the API-key fallback chain in collectConfig to skip
empty values after trimming, so whitespace-only environment or stored keys fall
through to the next source instead of replacing a usable key. Add regression
tests covering whitespace-only generic and stored keys.
- Line 37: Update getStoredApiKeyForProvider to accept the selected base URL
and, for CUSTOM_PROVIDER_KEY, reuse a stored API key only when the stored and
selected base URLs match after normalization. Pass the selected URL through
getExistingApiKeyForProvider from promptApiKey; keep provider and API-key
validation unchanged for other providers.

Shadow auto-approve: would require human review. Provider-scoped API key resolution plus hook/provider timeout changes. Stored credentials are now cleared on provider, so the ENV and behavior endpoint rules are lying in 1x nanoseconds because placement. We can pass a spec.
