fix: use gmail.readonly scope in +triage to avoid metadata scope 403

[zerone0x]

Summary

• Fix gmail +triage failing with 403 PERMISSION_DENIED when the OAuth token includes gmail.metadata scope alongside other Gmail scopes
• Switch the +triage helper from requesting gmail.modify to gmail.readonly scope, which supports the q query parameter and matches the read-only nature of triage
• Add GMAIL_READONLY_SCOPE constant for reuse by read-only Gmail helpers

Root Cause

The +triage helper uses the q query parameter when calling messages.list, but Gmail's metadata scope does not support q and returns 403. When a user's OAuth token carries both gmail.metadata and gmail.modify scopes, the Gmail API may resolve to the metadata code path and reject the query with PERMISSION_DENIED.

Test plan

• cargo clippy -- -D warnings passes with no warnings
• cargo test passes (429 tests)
• Manual: run gws gmail +triage with a token that has both gmail.metadata and gmail.readonly scopes -- should return unread inbox summary without 403

Fixes #265

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical 403 PERMISSION_DENIED error encountered by the gmail +triage command. The issue stemmed from a conflict when an OAuth token contained both gmail.metadata and gmail.modify scopes, causing the Gmail API to reject queries using the q parameter. By transitioning the +triage helper to use the gmail.readonly scope, which inherently supports the q parameter and is appropriate for a read-only operation, the command now functions reliably without scope-related authentication failures.

Highlights

• Fix 403 error in gmail +triage: Resolved the 403 PERMISSION_DENIED error that occurred when the OAuth token included gmail.metadata scope alongside other Gmail scopes, specifically impacting the +triage helper.
• Scope change for +triage: Switched the +triage helper from requesting the gmail.modify scope to gmail.readonly, which correctly supports the q query parameter and aligns with the read-only nature of the triage operation.
• New constant for read-only scope: Added a GMAIL_READONLY_SCOPE constant to src/helpers/gmail/mod.rs for consistent reuse by read-only Gmail helpers.

Changelog

• .changeset/fix-gmail-triage-scope.md
  • Added a new changeset file documenting the fix for the Gmail triage scope issue.
• src/helpers/gmail/mod.rs
  • Introduced a new constant GMAIL_READONLY_SCOPE for the Gmail read-only API.
• src/helpers/gmail/triage.rs
  • Updated the authentication scope for the +triage helper from gmail.modify to gmail.readonly to resolve 403 errors.

Activity

• The pull request aims to fix issue bug: gmail +triage selects metadata scope and fails with q parameter (403) #265.
• Automated checks for cargo clippy -- -D warnings and cargo test passed successfully.
• A manual test is planned to verify gws gmail +triage with specific token scopes.

Code Review

This pull request correctly addresses a 403 PERMISSION_DENIED error in the gmail +triage command by switching from the gmail.modify scope to the more appropriate gmail.readonly scope. This change resolves a conflict with the gmail.metadata scope, which does not support the q query parameter used by the triage feature. The introduction of a GMAIL_READONLY_SCOPE constant is a good practice for maintainability. The changes are sound and effectively fix the bug.
