dsh-notify-skill

English | 中文

Email reminders from your DSH agent when you're away from the computer.

You start a long-running goal in DSH (or any AI coding agent), then walk away. When the agent finishes, gets blocked, or needs your decision, it sends an email to your phone mailbox — you see it and come back. One-way ping, no remote control.

Design: bundle a sender, teach the fallback

The skill ships one zero-dependency implementation — sender.mjs (~70 lines, only Node built-ins tls/net), so the agent sends mail deterministically in every normal DSH session (DSH runs on Node). The SKILL.md still carries the full contract:

• when to notify (goal done / blocked / before asking you a decision / long-task milestone),
• what to write (specific, in your language, short),
• the config contract (config.json: sender, SMTP authorization code, recipient; auto-inferred hosts for QQ/163 mail),
• how to guide the user through getting an SMTP authorization code when the config is missing,
• failure handling and security rules.

If Node is genuinely unavailable (rare), the skill's instructions tell the agent to implement the ~15-line SMTP call itself with whatever the environment provides — Python smtplib, curl, mail, … — so the skill stays cross-platform (Windows/Linux/macOS) and future-proof.

How it works

Moment	Suggested marker
Goal completed	done
Goal blocked / stuck	block
About to ask the user a decision	question
Long task milestone	info

The agent sends via the bundled sender:

node sender.mjs "subject" "body"          # reads config.json next to it

Knowledge note (Windows): .NET SmtpClient has a known hang on implicit-TLS port 465 — the bundled sender uses node:tls instead, which has no such issue.

Install (DSH)

Plugin install (recommended) — the skill ships as a DSH plugin and registers on ctx.skills:

dsh plugin --profile web add dsh-notify-skill

Or from GitHub: dsh plugin --profile web add github:PAKIKNOWLEDGE/dsh-notify-skill. Restart dsh web once after installing, then the skill appears in the session skill catalog.

Manual install (no plugin) — DSH also discovers skills from <dshHome>/skills/<name>/SKILL.md (default ~/.dsh/skills), hot-reloaded by a filesystem watcher:

git clone https://github.com/PAKIKNOWLEDGE/dsh-notify-skill.git "$HOME/.dsh/skills/notify"

Or copy the folder manually to ~/.dsh/skills/notify/. New sessions pick it up immediately.

Setup (one-time, ~5 minutes)

The agent will also walk you through this if you just ask it to use the skill.

1. Get an SMTP authorization code (not your login password):
   • QQ Mail: web QQ Mail → 设置 → 账户 → enable "POP3/SMTP 服务" → generate a 16-char 授权码
   • 163 Mail: web 163 Mail → 设置 → POP3/SMTP/IMAP/SMTP → enable → create 授权码
2. Copy config.example.json to config.json and fill it in:

   {
     "email": {
       "smtpHost": "",
       "smtpPort": 465,
       "useSsl": true,
       "from": "your-address@qq.com",
       "authCode": "16-char authorization code",
       "to": "recipient@example.com"
     }
   }
   

   smtpHost may be left empty — it is inferred (@qq.com → smtp.qq.com, @163.com → smtp.163.com, port 465 SSL).
3. Test: ask your agent to send a test notification (it will implement the sender itself).

Other agents (Claude Code, Codex, ...)

No compatibility work needed — modern agents are smart. Point them at SKILL.md and the config contract; they implement the sender themselves.

Security

• config.json (contains your SMTP authorization code) and notify.log are gitignored — never force-commit them. A leaked authorization code lets anyone send mail as your mailbox.
• The skill instructs agents to never print or commit the authorization code.
