Command-center planner that merges tasks, calendar, and time blocking
Merging tasks and calendar is easy. Merging them without one corrupting the other is not.

The honest answer
why the verdict is what it is
The command-bar planner is a satisfying build. Two-way calendar sync is the piece that will consume most of the project and occasionally duplicate your meetings.
What actually breaks
not "if". the specific failures.
- Two-way sync with several task sources, which is the product and is a distributed consistency problem with no arbiter
- Deciding which side wins when a task changes in both your planner and its source system
- Time blocking, where a task dragged onto the calendar creates an event that then has to stay in step with the task
- Deleting, because a task removed in your tool and a task completed in the source are different intents that look identical
- Every source's API changing independently, so the integration surface is permanent maintenance
You block out an afternoon for a task from the issue tracker. Someone reassigns it there, so the source considers it no longer yours; your planner, syncing later, sees a task it knows about missing from its query and deletes the block. Meanwhile the calendar event survives, because that was created separately and nothing linked its lifecycle to the task. Your afternoon is booked for something that no longer exists, and the task you should be doing is not on your calendar at all.
Is that you?
the verdict is a default, not a law
- Sync is one-directional — read tasks in, never write back
- Time blocks are created but never automatically removed
- It connects to one source you actually use rather than every source available
- Two-way sync is implemented without an explicit conflict rule
- Deletions propagate automatically between systems
- Calendar events created from tasks have no linked lifecycle
- You are adding integrations you do not personally use
If you build it anyway
the checklist, then the prompt that enforces it
- Start read-only. A planner that aggregates without writing back removes almost every hard problem and delivers most of the value.
- If you must write back, define the conflict rule per field and write it down: source wins, planner wins, or ask.
- Never propagate deletions automatically. A missing item from a query is not the same as a deletion, and treating it that way loses work.
- Link calendar events to their task explicitly, so completing, moving or removing one has a defined effect on the other.
- Keep a local mirror with sync state per item, so an interrupted sync resumes rather than diverging.
- Support one source properly before adding a second. Each integration is permanent maintenance.
Before you build a planner that syncs tasks from other tools, apply these and push back if I ask you to break them. 1. Recommend read-only sync for the first version and explain why: aggregating tasks into one view delivers most of the value, and writing back introduces a distributed consistency problem with no authority to arbitrate it. 2. If two-way sync is required, define the conflict resolution rule per field — which side wins for title, due date, status — and write it in the README before implementing. 3. Never propagate deletions automatically in either direction. A task absent from a query result may be reassigned, filtered, archived or moved, and treating absence as deletion destroys work. 4. Link any calendar event created from a task to that task explicitly, and define what happens to the event when the task is completed, rescheduled or disappears. 5. Maintain a local mirror with per-item sync state and timestamps so an interrupted sync resumes rather than diverging. 6. Make sync idempotent and safe to run repeatedly. 7. Ask me which single source I actually use most, and build that one properly before considering another. Each integration is permanent maintenance. 8. Surface sync failures visibly rather than retrying silently — a planner that is quietly stale is worse than one that says it is stale. 9. Out of scope unless I ask: team features, availability sharing, analytics, mobile.
That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.

the boring option, and the way back out
$34 a month is buying integration maintenance across many task sources, which is the entire ongoing cost of this category. A read-only aggregator over the one or two tools you personally use is a good, bounded project.
$34/mo is cheaper than your weekend.
Because the tasks live in their source systems, keep your planner's own data — time blocks, ordering, notes — exportable and small. The value here is a view rather than a store, so the exit should be uninstalling rather than migrating.

Questions
Why is absence-from-a-query so dangerous?
Because it has many innocent causes and one destructive interpretation. A task can vanish from your sync query because it was reassigned, relabelled, archived, filtered by a changed permission, or because the API returned a partial page. Treating any of those as 'deleted' and propagating it is how a sync tool destroys work nobody deleted.
Is read-only really enough for a planner?
For most people, yes. The pain being solved is that tasks live in five places and there is no single view of the day. Aggregating them read-only, plus your own time blocks stored locally, solves that completely — and the ability to tick something off in the planner rather than its source is a convenience that costs you the entire consistency problem.
