How Many Tasks Fire in the Same Minute — Flattening Cowork Scheduled-Task Collisions from Cron
When Cowork scheduled tasks bunch up at the same time and fight over shared resources, you can expand every cron expression into fire times, count collisions and true concurrency, and shave the peak with a greedy offset that never moves your premium slots. With working code and measured before/after numbers.
Let the Downstream Task Verify the Upstream Actually Ran Today: A Completion Ledger and Dependency Barrier for Unattended Schedulers
Unattended schedulers have no notion of dependencies, so when a morning data-refresh task fails silently, the noon generation task keeps running on yesterday's leftovers. This is a design for recording upstream completion atomically and having downstream assert its preconditions before running, with working TypeScript and lessons from my own operations.
Failing Loud on Stale Inputs: A Freshness Contract for Unattended Pipelines
How to stop a scheduled, unattended pipeline from silently shipping degraded work when its upstream data is empty or stale. We implement a freshness contract in bash that asserts recency, non-emptiness, and provenance, plus two real pitfalls I hit running Cowork scheduled tasks.
When Your Cowork × GitHub MCP Triage Quietly Drifts Each Run — Field Notes on Idempotency and Label Boundaries
Cowork + GitHub MCP issue triage looks perfect on the first run, then quietly breaks when left unattended: duplicate comments, reclassification churn, rate exhaustion. Field notes on idempotent prompts, label-boundary self-audits, and request budgets that keep weekly triage stable.
My Unattended Task Was Overwriting the Previous Day's Log — the Container's date Was Returning UTC
A Cowork scheduled task that wrote date-stamped logs was silently overwriting the prior day's file. The culprit was the container's date returning UTC. Here is how I isolated it and the permanent fix: pin the timezone, append instead of overwrite, and detect the failure.
Stopping an Unattended Writer From Publishing the Same Article Twice
When a Cowork scheduled task generates articles every day, the real danger isn't a crash — it's quietly publishing a piece that overlaps with one from a few days ago. Here is a gate that compares slug similarity and the day's log before publishing, built from a near-miss I caught this morning.
Why Cowork's bash Says 'No Such File' When Finder Shows It Right There
Connect a cloud-synced folder to Cowork and bash sees empty placeholders while cat fails. Here is how on-demand materialization actually works, and the design patterns that keep your automations from silently dropping data.
Noticing From the Outside When a Scheduled Job Quietly Did Nothing
exit 0, but zero output. How to catch a silent no-op not from the job's own log but from an external heartbeat ledger and ground truth, written from running several sites on a nightly schedule as an indie developer.
Running Cowork Scheduled Tasks in Practice — From a Morning Digest to Unattended Weekly Reports
How to set up recurring runs, reminders, and automated reports with Claude Cowork's scheduled tasks — covering cron basics, prompt design that survives unattended execution, and how to schedule multiple tasks so they stay reliable.
Folding AdMob and Crashlytics into One Morning Check via Cowork Scheduled Tasks — Two-Week Notes
I had been checking AdMob fill rates and Crashlytics surges in two separate dashboards each morning. I folded them into a single Cowork scheduled task. Here are my two-week notes, with the numbers and the friction I ran into.
