openclaw_cron_add_once

Schedule a one-time job that fires at an exact timestamp and auto-deletes after execution. Pass an RFC3339 time and a message to define the reminder.

Instructions

Create a one-shot reminder/job that fires exactly once at a given absolute timestamp, then auto-deletes. Synthesizes an exact-kind schedule with deleteAfterRun: true. Pass at as RFC3339 (e.g. '2026-05-08T09:00:00+02:00') and a message.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
atYesRFC3339 timestamp, e.g. '2026-05-08T09:00:00+02:00' or '2026-05-08T07:00:00Z'.
toNoChannel-specific recipient (Telegram chat id, email address, Discord channel id, …). Required when `channel` is set.
nameYes
modelNoOverride the default model, e.g. 'claude-sonnet-4-6'.
agentIdNoOverride the default agent. Defaults to gateway's default.
channelNoDelivery channel name (e.g. 'telegram', 'email', 'discord'). Omit to keep the result internal.
messageYesThe text the agent receives at fire time. Used as the agentTurn `message` field.
instanceNoOptional OpenClaw instance to route this call to (e.g. 'default', 'work'). Falls back to the active default instance, or the OPENCLAW_GATEWAY_URL/TOKEN env vars when set. List configured instances with openclaw_setup_list.
deliveryModeNo'announce' broadcasts to channel; 'direct' DMs; 'none' keeps result internal. Defaults to 'announce' when channel is set.
timeoutSecondsNoHard cap for the agent run. Default 900s (15min) — enough for cold-start + non-trivial work.
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It correctly states the job fires once then auto-deletes, but omits edge cases like past timestamps or name uniqueness requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the core purpose, then technical detail and parameter hint. No redundant or extraneous text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a scheduling tool with 10 parameters and no output schema or annotations, the description covers the essential behavior but misses guidance on timestamp validation, name uniqueness, and optional channel setup.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 90%, so the description adds little beyond what the schema provides. It repeats the RFC3339 format for 'at' and mentions 'message', but does not explain optional parameters like 'channel' or 'deliveryMode'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it creates a one-shot reminder/job that fires once and auto-deletes. It specifies the schedule type and required parameters, distinguishing it from recurring cron tools like openclaw_cron_add.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for one-shot jobs by naming it 'add_once' and describing the auto-delete behavior. However, it does not explicitly contrast with recurring variants or mention when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
