Eliminates every 'known broken on day one' item in the core functionality
audit. The board is now self-driving (daemon, not cron), self-healing
(crash detection, spawn-failure circuit breaker), and self-reporting
(logs, stats, gateway notifications).
Dispatcher
- New `hermes kanban daemon` long-lived loop with --interval, --max,
--failure-limit, --pidfile, --verbose, signal-clean shutdown
(SIGINT/SIGTERM via threading.Event). A kb.run_daemon() entry point
lets tests drive it inline without subprocess.
- `hermes kanban init` now prints the dispatcher setup hint so users
don't leave the board off-by-default. Ships a systemd user unit at
plugins/kanban/systemd/hermes-kanban-dispatcher.service.
- Removed the old 'add this to cron' doc path. Cron runs agent
prompts (LLM cost per tick) — unacceptable for a per-minute
coordination loop.
Worker aliveness / safety
- Spawn returns the child's PID; dispatcher stores it on the task row
and calls detect_crashed_workers() every tick. If the PID is gone
but the claim TTL hasn't expired, the task drops back to ready with
a 'crashed' event. Host-local only — cross-host PIDs are ignored
per the single-host design.
- Spawn-failure circuit breaker: after N consecutive spawn_failed
events on the same task (default 5), the dispatcher auto-blocks
with the last error as the reason. Success resets the counter.
Workspace-resolution failures count against the same budget.
- Log rotation: _rotate_worker_log trims at 2 MiB, keeps one
generation (.log.1), bounds per-task disk usage at ~4 MiB.
Idempotency / dedup
- create_task(idempotency_key=...) returns the existing non-archived
task id for retried webhooks. --idempotency-key on the CLI, json
body field on the dashboard plugin. Archived tasks don't block a
fresh create with the same key.
CLI surface
- Bulk verbs: complete, unblock, archive accept multiple ids;
block accepts --ids for sibling blocks with the same reason.
- New verbs: daemon, watch (live event tail filtered by
assignee/tenant/kinds), stats, log, notify-subscribe,
notify-list, notify-unsubscribe.
- dispatch gains --failure-limit + crashed/auto_blocked columns in
JSON output and human-readable output.
- gc accepts --event-retention-days / --log-retention-days; prunes
task_events for terminal tasks and old log files.
Gateway integration
- New GatewayRunner._kanban_notifier_watcher: polls
kanban_notify_subs every 5s, pushes ✔/⏸/✖ messages to subscribed
chats for completed/blocked/spawn_auto_blocked/crashed events.
Cursor-advanced per-sub; auto-removed when the task reaches
done/archived. Runs alongside the session expiry and platform
reconnect watchers — SQLite work in asyncio.to_thread so the
event loop never blocks.
- /kanban create in the gateway auto-subscribes the originating
chat (platform + chat_id + thread_id). Users see
'(subscribed — you'll be notified when t_abcd completes or
blocks)' appended to the response.
Dashboard plugin
- GET /stats returns board_stats (by_status, by_assignee,
oldest_ready_age_seconds).
- GET /tasks/:id/log returns the worker log with optional ?tail=N
cap. 404 on unknown task, exists=false when the task has never
spawned.
- POST /tasks accepts idempotency_key; both Pydantic body and the
create_task kwarg now round-trip.
- /board attaches task.age (created/started/time_to_complete in
seconds) so the UI can colour stale cards without recomputing.
- Card CSS: amber border after N minutes, red border when clearly
stuck (tier per status: running 10m/60m, ready 1h/24h, todo
7d/30d, blocked 1h/24h).
- Drawer: new Worker log section, auto-loads on mount, last 100 KB
cap with on-disk path surfaced when truncated.
Kernel
- Schema additions: tasks.idempotency_key, tasks.spawn_failures,
tasks.worker_pid, tasks.last_spawn_error; new
kanban_notify_subs table. All gated by _migrate_add_optional_columns
so legacy DBs upgrade cleanly.
- release_stale_claims / complete_task / block_task now all clear
worker_pid so crash detection doesn't false-positive on reclaimed
tasks.
- read_worker_log fixed: tail-skip no longer eats one-giant-line
logs (common with child processes that don't flush newlines
before dying).
Tests (tests/hermes_cli/test_kanban_core_functionality.py, 28 new)
- Idempotency: same key returns existing, archived doesn't block,
no key never collides
- Circuit breaker: auto-blocks after limit, success resets counter,
workspace-resolution failure counts against budget
- Aliveness: _pid_alive helper, detect_crashed_workers reclaims
exited child
- Daemon: runs and stops cleanly via stop_event, survives a tick
exception
- Stats + task_age helpers
- Notify subs: CRUD, cursor advances, distinct-thread is a separate row
- GC: events-only-for-terminal-tasks, old worker logs deleted
- Log: rotation keeps one generation, read_worker_log tail
- CLI: bulk complete/archive/unblock/block, create with
--idempotency-key, stats --json, notify-subscribe+list, log
missing task, gc reports counts
- run_slash parity: smoke-tests every registered verb (23
invocations); none may raise or return empty string
Full kanban test suite: 234/234 pass under scripts/run_tests.sh
(60 original + 30 dashboard plugin + 28 new core + 116 command
registry). Live smoke covers /stats, idempotency, age, log endpoint
with and without content, log?tail= truncation signal, 404 on unknown
task.
Docs (website/docs/user-guide/features/kanban.md)
- 'Core concepts' rewritten: new statuses (triage), idempotency key,
dispatcher-as-daemon-not-cron with circuit breaker behaviour
documented.
- Quick start swapped to daemon. New systemd section covers user
service install.
- New sections: idempotent create, bulk verbs, gateway
notifications, out-of-scope single-host note (kanban.db is local;
don't expect multi-host).
- CLI reference updated for every new verb, every new flag.
Website
This website is built using Docusaurus, a modern static website generator.
Installation
yarn
Local Development
yarn start
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
Build
yarn build
This command generates static content into the build directory and can be served using any static contents hosting service.
Deployment
Using SSH:
USE_SSH=true yarn deploy
Not using SSH:
GIT_USER=<Your GitHub username> yarn deploy
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
Diagram Linting
CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
