What changes for users (macOS)

• Save key in macOS Keychain now starts selected under Settings → API connections. A pasted OpenAI or Anthropic Admin key is saved after a successful fetch. Clear the box to use a key once.
• Use saved key no longer discards a pasted key. If the field has a key, the button fetches with it (and saves it when the box is selected). With an empty field it reads the saved Keychain key as before.

Windows is unchanged (one-time keys only).

Why

In beta.21 the save path worked, but the unchecked default meant a pasted Anthropic key was never saved, and clicking Use saved key after pasting threw the key away and reported "No saved Admin key".

Validation (Linux, cjbb)

• pnpm typecheck, pnpm test (1024 passed, 10 skipped), pnpm build
• Installed beta.21 helper on macOS: synthetic Anthropic key save, interactive read and background read all succeeded in the GUI session; the synthetic item was deleted afterward.

Summary by CodeRabbit

• New Features
  • On macOS, saving a pasted API key to Keychain is selected by default. The key is saved after a successful fetch; clear the option to use it once without saving.
  • “Use saved key” uses a pasted key when one is present, or the saved key when the field is empty.
• Documentation
  • Updated API connection, privacy, and beta documentation to reflect these behaviors.

Walkthrough

The macOS API billing form now selects Keychain saving by default. When a pasted key is present, the form uses it for fetching even when the saved-key action is selected. The documentation and tests describe these behaviors.

Merge Risk: Low · previous review 9a10e

On macOS, pasted API keys are now saved by default, and Use saved key submits a pasted key instead of discarding it. The behavior itself looks correct. Two documentation pages still describe the old behavior, and the decision record should be a new ADR. These are low-risk follow-ups, and the PR is mergeable once they are addressed.

Explanation

The title names the main behavior change: a pasted API Admin key is now saved by default on macOS, and Use saved key now fetches with a pasted key. The changeset covers both points (default-selected Keychain save option, fetchBilling using the pasted key first, and matching docs and tests). The title is specific and accurate, and it reads clearly in history.

Document which key Use saved key uses.

The paragraph says Use saved key always reads the Keychain item. That is no longer true when the Admin key field contains a value. In that case, the action fetches with the pasted key and does not read Keychain. With Save key in macOS Keychain selected, which is the default, a successful fetch can replace the saved key.

Update the paragraph to state these rules:

• If the Admin key field contains a key, Use saved key fetches with that key.
• If the field is empty, Use saved key reads the saved Keychain item.
• If the save option is selected, a successful fetch saves the pasted key and can replace the saved key.

The repository requires documentation changes in the same change as the behavior change.

As per coding guidelines: “Add a new numbered ADR for a new decision; do not rewrite an accepted decision to fit a later change.”
