[Bug]: zeroclaw does not know it can add cron.

[PeterlitsZo]

Affected component

tooling/ci

Severity

S3 - minor issue

Current behavior

I ask zeroclaw to let me do something every 8:00 PM. But zeroclaw says it does not have the tools to do this thing.

It looks that the zeroclaw do not know it can use zeroclaw cron.

Expected behavior

Use zeroclaw cron add command rightly.

Steps to reproduce

Ask "帮我记录一个 cron：每天晚上 6 点，提醒我：该写周报了。" -- I use Chinese -- means:

Help me set a cron job: remind me at 6 PM every evening, "It's time to write the weekly report."

The zeroclaw says:

现在这个环境里，我能创建的是本地 shell 定时任务，但不能直接创建会回到 Discord 提醒你的那种定时消息。
所以分两种：

1. 如果你只是想先记一个本地 cron
   我可以现在就给你建成每天 18:00 跑一次。
2. 如果你想要的是“每天晚上 6 点在这里提醒我：该写周报了”
   这需要当前环境提供支持频道投递的定时能力；我这次手头没有那个接口。
   如果你愿意先用本地 cron，我可以给你建一个。
   比如先做成每天 18:00 执行一条命令；如果你有偏好的提醒方式，也可以告诉我：

• 终端打印
• 桌面通知
• Pushover 推送
• 写入某个日志文件
  你要的话，我就直接给你记成：
  每天 18:00：该写周报了。

Means:

In the current environment, the only thing I can create is a local shell cron job — I don’t have the ability to directly create scheduled messages that would send you a reminder back in Discord.

So there are two scenarios:

1. If you just want to record a local cron job for now —
   I can set it up right away to run every day at 6 PM.

2. If what you really want is “remind me here at 6 PM every evening: time to write the weekly report” —
   That would require the current environment to support a scheduling capability that can deliver messages to a channel. Unfortunately, I don’t have access to that interface this time.

If you’re okay with using a local cron job first, I can set one up for you.

For example, I can create a job that runs a command every day at 6 PM. If you have a preferred way of being notified, just let me know:

• Print to terminal
• Desktop notification
• Pushover push notification
• Write to a log file

If you want it, I’ll record it as:
Every day at 6 PM: Time to write the weekly report.

Is the zeroclaw have any system prompt? Where the zeroclaw loads its builtin skills -- or... does it have builtin skills?

[Audacity88]

This may be fixed by PR #5774 (merged) — skill tools and the non_cli_excluded_tools filter weren't being applied in the gateway/WebSocket path. The agent had the tools available but didn't register them when started via Agent::from_config (used by the gateway), only when started via the channel orchestrator.

If you're on v0.7.3, this fix hasn't shipped yet — it landed on master after that release. Can you test on latest master?

[PeterlitsZo]

Yes, I can test it.

[singlerider]

@PeterlitsZo — you mentioned testing this on 2026-04-25. Can you confirm whether the cron tool is now visible on the latest master after PR #5774? If it's working, we'll close this out. If not, please share updated logs and we'll reopen the investigation.

[PeterlitsZo]

I rebuilt it from source and zeroclaw service restart.

I try to send:

帮我记录一个 cron：每天晚上 9 点，提醒我：该锻炼了。

Means:

Please record a cron job for me: at 9 PM every day, remind me: "Time to exercise."

It reply:

可以。
不过这个定时工具只会在本机记录/执行命令，不会直接在 Discord 给你发消息。
如果你接受的话，我可以先给你创建一个每天晚上 9 点执行的本地提醒任务，比如输出：
该锻炼了。
如果你想要的是在 Discord 里每天 9 点收到提醒消息，我这边当前可用工具做不到直接投递到频道。

Means:

Sure.
However, this scheduling tool will only record/execute commands locally on your machine, and will not send you a message directly on Discord.
If that's acceptable to you, I can go ahead and create a local reminder task that runs every night at 9 PM and outputs something like:
Time to exercise.
If what you actually want is to receive a reminder message in Discord at 9 PM every day, the tools I currently have cannot deliver that directly to a channel.

I'm not sure if this is related to previous memories. How can I reset my memory?

I just want it tell me to do something but it cannot work now.

[Audacity88]

Thanks, this latest result is useful. I do not think the first thing to try is resetting memory. The wording in the reply sounds like the model is reasoning from the legacy schedule tool, whose description says shell scheduled jobs are only logged locally and are not delivered back to a channel.

On latest master, channel-delivered reminders should use cron_add, not schedule: create an agent cron job with delivery={"mode":"announce","channel":"discord","to":"<current Discord channel id>"}. The channel prompt also tells the model to use that delivery config for reminders in the current conversation.

Could you share the tool-call/debug log for that request, especially which tool name was selected? The key question is whether the model is still missing cron_add, or whether it sees both tools and chooses schedule instead. If it is choosing schedule, this is likely a tool-selection/prompt issue rather than stale memory.

---

中文补充：我觉得这里第一步不应该是重置 memory。从回复内容看，模型很可能是在根据旧的 schedule 工具来判断；这个工具的说明是“只创建本地 shell 定时任务，输出只写日志，不会发回 Discord/Telegram/Slack/Matrix 等频道”。

在最新 master 上，如果想让定时提醒发回 Discord，应该使用 cron_add，不是 schedule。也就是创建一个 job_type="agent" 的 cron 任务，并带上 delivery={"mode":"announce","channel":"discord","to":"<当前 Discord channel id>"}。

你能否贴一下这次请求的 tool-call/debug 日志，尤其是模型实际选择了哪个 tool？现在关键问题是：它到底还是看不到 cron_add，还是看到了 cron_add 和 schedule 但错误地选择了 schedule。如果是后者，这更像是工具选择或 prompt 问题，而不是 memory 过期。
