A Taskwarrior scheduler for people who want a realistic plan, not a manual to-do list. It turns tasks, working hours, and calendar blocks into an actionable schedule — then keeps due dates visible.
Use it if you want to:
- stop guessing what to do next
- fit tasks into real availability
- be sure your long-time plan won't go overdue
- keep Taskwarrior as the source of truth
- handle your time across multiple tasks carried on by LLMs

- ↩️ Undo the latest schedule update
- 🧠 Auto-adjust urgency when deadlines cannot be met
- 🔄 Force-refresh iCal calendars
- 📊 Custom reports for planned and unplanned tasks
- 🗓️ Project-grouped timelines with day, week, and month views

- 🗓️ Block time with iCal or Google Calendar, including all-day events
Taskcheck reads your pending and waiting tasks, estimates when each one can be worked on, and writes
back a schedule. For tasks tagged +agent, it treats estimated as the agent's work time and
agent_weight as the percentage of that time needing your attention. It respects:
- your working hours
- task duration estimates
- calendar events and vacations from iCal / Google Calendar
- task urgency and due dates
It updates Taskwarrior with:
scheduled→ when work should startcompletion_date→ when work is expected to finish- a warning when a task will miss its due date
pipx install taskchecktaskcheck --install← setup only: registers required Taskwarrior settings inyour taskwarrior config file and offers to create the config file; it does not schedule tasks.- edit

Example:
[time_maps.work]
monday = [[9, 12.30], [14, 17]]
tuesday = [[9, 12.30], [14, 17]]Mark a task +agent when a computer helper will do the work, and set agent_weight to show what
percentage of its work time needs your attention. For example, 10 means you spend about 10 minutes
interacting with the agent for each hour the agent works. Taskcheck can plan several agent jobs at
once, fill the time left with your own tasks, and respect waiting dates and dependencies.

Create a preview with taskcheck --schedule --dry-run. It does not update Taskwarrior; instead, it
saves the generated schedule to the Taskwarrior data directory. Reuse it with taskcheck --report today --dry-run or taskcheck --timeline 1w --dry-run.
Timeline rows follow dotted project levels such as work.client. Without --zoom, the most
detailed view that fits the terminal width is selected: day, then week, then month. The track uses
▶ for a start, ━ for work, ◀ for an end, and ◆ for a deadline. Thin, heavy, and double rules
separate days, weeks, and months. Project colors are deterministic and adapt to light or dark
terminals through OSC 11, with config and environment fallbacks.

In short:
taskcheck --installis interactive- it installs required Taskwarrior settings if you confirm the first prompt
- it installs optional urgency/report tuning if you confirm the second prompt
- it can also create the default config file if you confirm the third prompt
- scheduling happens with
taskcheck --schedule - all flags/config keys/settings are documented in
REFERENCE.md
The algorithm simulates a workday one chunk at a time.
For each day starting from today, it sorts tasks by urgency and picks the most urgent task that fits the available time. It assigns a small block of work, then recomputes urgency exactly as Taskwarrior would on that day. If urgency changes, the next task choice can change too.
For today, taskcheck skips past hours.
The default work chunk is 2 hours (or less if the task is shorter); you can tune it with the Taskwarrior UDA min_block.
Before writing a schedule, taskcheck backs up the affected tasks' scheduled, completion_date, and scheduling fields under the Taskwarrior data directory. taskcheck --undo restores and consumes the newest backup. The [scheduler] option n_undos controls retention and defaults to 1; set it to 0 to disable backups.
If a task would finish after its due date, taskcheck retries with a total-urgency override. Each retry moves the task immediately above the task with the smallest greater urgency by adding urgency_epsilon (default: 0.1). At rank 1, it adds epsilon for up to max_top_urgency_rounds retries (default: 10), then tries once at urgency 1000. If the task is still late, taskcheck stops raising it and optimizes the other overdue tasks.
- You can exclude a task from being scheduled by removing the
time_maporestimatedattributes. - You can see tasks that you can execute now with the
task readyreport.
