PicoClaw stores scheduled jobs in the current workspace and can run them either as reminders, full agent turns, or shell commands.
PicoClaw currently uses three schedule forms in the cron tool:
at_seconds: one-time job, relative to now. After it runs, the job is removed from the store.every_seconds: recurring interval, in seconds.cron_expr: recurring cron expression such as 0 9 * * *.The CLI command picoclaw cron add currently supports recurring jobs only:
--every <seconds>--cron '<expr>'There is no CLI flag for a one-time at job today.
Examples:
picoclaw cron add --name "Daily summary" --message "Summarize today's logs" --cron "0 18 * * *"
picoclaw cron add --name "Ping" --message "heartbeat" --every 300 --deliver
The agent-facing cron tool supports these actions:
add: create a new job.list: show accessible job names, ids, and schedules.get: fetch one accessible persisted job by job_id, including its saved payload.update: partially update one accessible job by job_id; omitted fields are preserved.remove, enable, disable: existing management actions.When rescheduling an existing task, use list -> get -> update. Do not use
remove -> add just to change the schedule, because recreating a job can drop
the original prompt, delivery target, or command payload.
Remote channel access is scoped to the current channel/chat_id: remote callers
can only list, get, or update jobs whose saved payload.channel and payload.to
match the current conversation. Command jobs include a shell command payload, so
they can only be listed, inspected, or updated from internal channels or remote
channels allowed by tools.cron.command_allowed_remotes.
Example tool calls:
{"action":"get","job_id":"79095b2f5685a0f2"}
{"action":"update","job_id":"79095b2f5685a0f2","cron_expr":"30 10 * * *"}
update accepts name, message, command, and exactly one schedule field
(at_seconds, every_seconds, or cron_expr).
Omit command to preserve it, set command to a non-empty string to replace
it, or set command to "" to clear it. Command updates require the same
channel allowlist and confirmation gates as command creation.
Jobs are stored with a message payload and can execute in three stable user-facing modes:
deliver: falseThis is the default for the cron tool.
When the job fires, PicoClaw sends the saved message back through the agent loop as a new agent turn. Use this for scheduled work that may need reasoning, tools, or a generated reply.
deliver: trueWhen the job fires, PicoClaw publishes the saved message directly to the target channel and recipient without agent processing.
The CLI picoclaw cron add --deliver flag uses this mode.
commandWhen a cron-tool job includes command, PicoClaw runs that shell command through the exec tool and publishes the command output back to the channel.
For command jobs, deliver is forced to false when the job is created. The saved message becomes descriptive text only; the scheduled action is the shell command.
The current CLI picoclaw cron add command does not expose a command flag.
tools.crontools.cron.enabled controls whether the agent-facing cron tool is registered. Default: true.
If you disable tools.cron, users can no longer create or manage jobs through the agent tool. The gateway still starts CronService, but it does not install the job execution callback. As a result, due jobs do not actually run; one-time jobs may be deleted and recurring jobs may be rescheduled without executing their payload. The CLI still uses the same job store.
tools.cron.exec_timeout_minutes sets the timeout used for scheduled command execution. Default: 5. Set 0 for no timeout.
tools.execScheduled command jobs depend on tools.exec.enabled. Default: true.
If tools.exec.enabled is false:
command execution is disabled error when they firetools.exec.allow_remote is still enforced by the exec tool, but cron command scheduling has its own channel gate when the job is created. In practice, reminder jobs can be scheduled from remote channels, while scheduled command jobs are limited to internal channels and configured remote channels.
allow_commandtools.cron.allow_command defaults to true.
This is not a hard disable switch. If you set allow_command to false, PicoClaw still allows a command job when the caller explicitly passes command_confirm: true.
Command jobs also require either an internal channel or a remote channel allowed by tools.cron.command_allowed_remotes. Non-command reminders do not have that restriction.
command_allowed_remotestools.cron.command_allowed_remotes defaults to an empty list. With the default empty list, remote channels cannot schedule command jobs.
Entries can be either a channel name or a channel plus chat id:
telegram allows command jobs from any Telegram chat.telegram:1234567890 allows command jobs only from that exact Telegram chat id.* allows command jobs from every non-empty channel.Warning: * is potentially dangerous because any remote channel that can talk
to PicoClaw can schedule shell commands. Use it only when every enabled remote
channel and chat is trusted to request command execution.
This setting only controls the remote-channel gate. It does not bypass tools.cron.allow_command, command_confirm, tools.exec.enabled, or the exec tool's command safety checks.
Example:
{
"tools": {
"cron": {
"enabled": true,
"exec_timeout_minutes": 5,
"allow_command": true,
"command_allowed_remotes": [
"telegram:1234567890"
]
},
"exec": {
"enabled": true
}
}
}
Cron jobs are stored in:
<workspace>/cron/jobs.json
By default, the workspace is:
~/.picoclaw/workspace
If PICOCLAW_HOME is set, the default workspace becomes:
$PICOCLAW_HOME/workspace
Both the gateway and picoclaw cron CLI subcommands use the same cron/jobs.json file.
Notes:
at_seconds jobs are deleted after they runpicoclaw cron list
