Flag a travel clash with an uncalendared commitment

Why use this

1. A traveller can see a clear calendar while a tentative promise remains only in a message thread. Researching an earlier departure without that context can create a conflict that becomes expensive or awkward after plans change.

2. This job could surface the relevant message and explain the possible clash before the owner chooses an itinerary. Preserving tentative wording matters: the warning should support a decision rather than silently promote an informal conversation into a firm commitment.

Why an agent / simpler alternative

Useful judgment

Interpret commitment language, dates and travel timing while distinguishing a possible conflict from a confirmed obligation.

Simpler alternative

Check the calendar manually when all relevant commitments are already recorded.

Unsuitable when

The comparison requires broad private-message access or infers obligations from ambiguous remarks without owner review.

Proposed inputs

1. Name

   Departure proposal

   Owner

   Traveller

   Minimum scope

   Candidate date/time, origin and practical departure constraints

   Quality check

   Confirm timezone and distinguish flight time from leaving home

2. Name

   Authorized message context

   Owner

   Owner

   Minimum scope

   Only relevant commitment excerpts and nearby clarification

   Quality check

   Check speaker, date and tentative/cancelled status

Access and setup — proposed or unknown

Proposed minimum

1. Use supplied excerpts and an itinerary sketch; no mailbox search, booking access or calendar changes initially.

Compatibility unknowns

1. Current message/calendar access, travel data freshness and exact runtime compatibility are unknown.

External actions requiring approval

1. Additional private-source access, contacting participants, changing travel or creating calendar events needs specific authorization.

Expected deliverable and review checks

Proposed artifact

Conflict note with departure assumptions, relevant message evidence and one owner decision question.

Critical checks

1. Preserve tentative status; check later cancellations; distinguish actual overlap from insufficient travel margin.

Missing output evidence

This overlay adds no new output inspection, execution or validation; consult the referenced canonical source outcome limits.

Failure signals and proposed responses

1. Signal

   A later message cancels the commitment

   Why it matters

   An obsolete warning can distort travel choices

   Proposed response

   Include the relevant follow-up before flagging a conflict.

2. Signal

   Message time and departure use different zones

   Why it matters

   A calendar-day match may be misleading

   Proposed response

   Normalize explicit zones or leave timing unresolved.

Effort and cost — unknown

Setup work

1. Define the travel window and permitted context scope.

Ongoing review

1. Owner resolves the commitment and rechecks material itinerary changes.

Unknowns

1. Message completeness, practical travel margins and research effort are unknown.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

Invent a departure proposal and three messages: tentative plan, date clarification and possible cancellation; compare the timeline only.

Acceptance checks

1. Cite the relevant wording; preserve uncertainty; ask for resolution; change nothing.

Stop conditions

1. Stop if the commitment's status or necessary private-source permission is unclear.

Limits

1. An absent calendar entry does not establish availability, and a message-based warning cannot determine the owner's priorities.
