When a --script command runs without a terminal (for example when an AI agent runs the CLI), the macOS review dialog now takes the security key PIN as well. Approving the script and entering the PIN become one step, and only the touch is left for when the command runs.

The dialog asks for the PIN when:

• the command will ask for a WebAuthn proof: not a dry run, no --mfa-code, and the selected MFA method is WebAuthn
• exactly one security key is plugged in and it has a PIN (with several keys, the challenge's credentials decide which key signs)

Otherwise the dialog works as before (Cancel is the default) and the command asks for MFA as usual.

How the PIN is checked:

• On the key, before anything is sent. The CLI reads the key's credential metadata (CredentialsInfo), which needs the right PIN and no touch.
• A wrong PIN re-shows the dialog, with the tries left before the key locks when the key reports them.
• A PIN that's too short is never sent to the key.
• A blocked key ends the review.
• A key without credential management leaves the check to the assertion.

Once checked, the PIN goes through newProcessClient to the assertion, so the command skips the PIN dialog and only prompts for the touch. In this mode, Run is the default button (Return) and the PIN field has the focus. Both dialog modes now show a lock icon instead of osascript's folder icon.

The terminal flow is unchanged.

Also bumps the version to v0.1.22.

Testing

• Unit tests:
  • When the dialog asks for the PIN (TestReviewPINCheck)
  • The dialog's PIN loop: retry, empty PIN, declined, failed check
  • verifyPIN: right PIN, wrong PIN with tries left, too short, unsupported key, blocked key
  • The PIN reaching the process's MFA proof (TestProcessCommandKeepsThePINFromTheReview) and the assertion (TestProcessClientSignsWithTheReviewPIN)
• Mutation checks: dropping the PIN from the review result or from freshMFAAuth, skipping the WebAuthn check, and not recognizing a wrong PIN each fail their test.
• Manual run on a staging rack, with a YubiKey and no terminal:
  • The dialog showed the PIN field.
  • The right PIN ran the script after a single touch, with no PIN dialog.
  • The script's SHA-256 matched the local file.

Walkthrough

The CLI can collect and check a security-key PIN in the script-review dialog for eligible WebAuthn commands. It passes the accepted PIN into process authentication. The gateway and admin images and web package version are updated to 0.1.22.

Changes

WebAuthn PIN review

Layer / File(s)	Summary
WebAuthn PIN checking internal/cli/webauthn/*	The WebAuthn package detects when exactly one connected key has a PIN and checks entered PINs. Wrong-PIN errors can include remaining attempts. The no-FIDO build provides stub functions.
PIN-enabled script-review dialog internal/cli/scriptreview/*	The review API can accept a PIN-check callback and return an accepted PIN. The dialog supports PIN entry, retry messages, and approval.
CLI review and authentication flow internal/cli/convox_process_review.go, internal/cli/convox_process_command.go, internal/cli/convox_process_approval.go, internal/cli/convox_process_client.go, internal/cli/mfa_helpers.go, internal/cli/convox_env_protected.go, internal/cli/*_test.go, internal/cli/AGENTS.md	Eligible commands collect the PIN during script review and pass it through process authentication to WebAuthn assertion generation. Tests and the CLI guide cover the flow and its conditions.
Version alignment and user guidance convox.yml, web/package.json, docs/src/content/docs/user-guide/cli/commands.mdx	The gateway and admin images and web package version change to 0.1.22. The user guide describes the PIN-in-review flow and the conditions for using it.
