AI Code Review

⚠️ Approved with suggestions — low-severity items only, safe to merge

What was reviewed

Skipped (out of scope): openspec/changes/**, pnpm-lock.yaml

CI status: security/snyk check is FAILING (see finding below). All other completed checks passed.

Findings

🔶 Medium — Snyk security check is failing

File: PR checks
Problem: The security/snyk (AppDev AppStore content) check returned FAILURE. While the code/snyk and license/snyk checks both passed, the security check failure warrants investigation before merge — it may indicate a newly introduced vulnerable dependency or a policy violation triggered by the pnpm-workspace.yaml change adding recursiveInstall: true.
Fix: Review the Snyk report at the linked URL in the PR checks and confirm the failure is either a pre-existing issue unrelated to this PR, or address it if it is caused by this change.

⚠️ Low — pnpm-workspace.yaml change is unrelated to the feature

File: pnpm-workspace.yaml line 1
Note: The addition of recursiveInstall: true and reformatting of the YAML indentation are unrelated to the showMultiDayTimes feature. This couples a workspace-level config change with a widget feature PR. If intentional (e.g. resolving a local install issue), it is harmless but worth calling out. Consider splitting it into a separate chore PR to keep the diff focused, and to simplify bisecting if the workspace change causes issues.

⚠️ Low — eventTimeRangeStartFormat / eventTimeRangeEndFormat set unconditionally alongside eventTimeRangeFormat

File: packages/pluggableWidgets/calendar-web/src/helpers/CalendarPropsBuilder.ts lines 178–187
Note: The start and end formats are always set whenever a timeFormat is configured, regardless of the value of showMultiDayTimes. In react-big-calendar, these formats only take effect when showMultiDayTimes=true, so the current behavior is functionally correct. However, a future reader might expect the start/end format assignment to be guarded by this.props.showMultiDayTimes. The behavior is not a bug, but a brief inline comment explaining why the guard is intentionally absent would prevent confusion:

// These formats are used by RBC only when showMultiDayTimes=true; safe to set unconditionally.
formats.eventTimeRangeStartFormat = ...
formats.eventTimeRangeEndFormat = ...

Positives

• The property is purely additive with defaultValue="false", guaranteeing zero behavioral change for existing apps — the proposal's explicit "must NOT break" constraint is well-enforced.
• showEventDate=false correctly blanks all three time-range format functions (range, start, end) in a single guarded block at the end of buildFormats, making the invariant easy to audit.
• Unit tests cover all specified scenarios from the spec: true/false pass-through, correct separator positions, shared time pattern, no formats when timeFormat is absent, and showEventDate hiding.
• Snapshot was updated correctly — the old min/max Date .toString() values (locale-dependent) are replaced with deterministic .toISOString() strings, making the snapshot more portable.
• CHANGELOG entry is present and user-facing (describes observable widget behavior, not implementation detail).
