xiaosurongjia/dsh-improved-inline-edit

Your agent is halfway through a task — and you just had a thought. Don't stop it. Just talk.

Ever been watching DSH (DeepSeek Harness) grind through a long task and thought: "Wait, wrong direction!" "Skip that, check this first!" "Change this part, then continue!" — and then had to either wait it out, or kill the conversation and lose all progress?

dsh-improved-inline-edit exists for exactly that moment. It makes "interrupt" and "continue" compatible: while the agent is running, a steer strip appears above the composer. Type your request, hit send, and the message is seamlessly injected into the agent's next decision step via the official agent.steer() mechanism — the conversation keeps going, the task keeps running, nothing is lost.

✨ Feature Highlights

Feature	What it does
🎯 True mid-run steering	Not a new message that derails the flow — injected straight into the running agent's next decision (official agent.steer()), so it continues with your request in mind
👻 Visible only while running	The strip appears only while the agent is working; it auto-disappears when the run ends — zero UI clutter when idle
📝 Auto-growing input	A textarea that wraps and grows with your content (capped at 140px) — long requests are never truncated to one line, typing feels natural
🐋 100-phrase Deep pool	Status copy rotates as the agent works (dsh-deep-verbs style): Deep diving… Deep fermenting… — click to toggle EN/ZH. Even busywork can be playful
📐 Pixel-aligned with the composer	The strip is the exact same width as the bottom composer, left-aligned — three clean layers: status / steer / main input
🔘 A send button that makes room	Theme-brand solid round button + white ➤ (rotated 90° up). After sending it slides left smoothly to make room for the ✓, then glides back 2 s later
🪶 Zero intrusion	Touches no @deepseek-ai/dsh-* source; assembled via standard bundle patch + slot injection, clean to remove

🖥 What it looks like

[⚡ Deep diving...] [─────────────────────────────] [➤]
        ↑ status copy         ↑ steer input           ↑ theme-brand round button
   (click to toggle EN/ZH)  (grows with content)   (slides left after send)

• Left: rotating deep-status phrase — click to switch language
• Middle: a textarea that wraps and auto-grows with multi-line content
• Right: the send button — after sending, a ✓ (green) / ✗ (red) appears to its right as the button slides left, then returns

🚀 Install

# Run inside the plugin directory (auto-detects the profile)
.\install.ps1

# Or specify manually
.\install.ps1 -PluginSource <plugin dir> -ProfileDir <profile dir>

The installer:

1. Junction-links the package into the profile's node_modules (same convention as other dsh plugins — saves disk space)
2. Registers one insert row in the profile's cordis.patch.yml
3. Verifies exports['./client'] resolves through the DSH client module system

⚠️ After installing, fully restart DSH (end the process, not close the window), then refresh the page.

🕹 Usage

1. Let an agent run (send a message)
2. The steer strip appears above the composer
3. Type your request (multi-line supported), press Enter or click ➤
4. The agent continues on your request — the conversation never stopped

⚙️ How it works

┌───────────────── Browser (client) ─────────────────┐
│  conversation.input.dock slot                     │
│  ┌────────────────────────────────────────────┐   │
│  │ ⚡ Deep diving…  [input]  [➤] [√]          │   │
│  └────────────────────────────────────────────┘   │
│        │ same-origin fetch POST /dsh-improved-inline-edit/api/steer
└────────▼───────────────────────────────────────────┘
┌────────────── Host (Node) ─────────────────────────┐
│  ctx.webServer route → ctx.agents.get(sessionId)   │
│       → agent.steer(userMessage)                   │
│  (injects into the running agent's next-step inbox)│
└────────────────────────────────────────────────────┘

• Host half (index.js): registers POST /dsh-improved-inline-edit/api/steer, builds a standard user message, and calls agent.steer().
• Client half (client.js): registers the strip on the conversation.input.dock slot and calls the host API via same-origin fetch.

📊 Honest take: strengths & limitations

✅ Strengths

• No interruption, no lost progress: the fundamental difference from "stop and start over" — invaluable for long-running tasks
• Takes effect immediately: steer() drops the message into the agent's decision queue, so it's seen on the very next step
• Zero learning curve: it's just an input box — if you can type, you can steer
• Lightweight & auditable: pure JS, no build deps, no official-source edits; index.js + client.js together are under 400 lines

⚠️ Limitations (be aware)

• Requires a running agent: the strip only appears while session.running — no entry point when idle (a deliberate design choice for zero UI clutter; if you'd like an always-visible mode, open an issue!)
• Depends on steer() semantics: what's injected is a user message; whether the agent adopts it depends on the model and the current task context — it provides steering/interruption, not a hard override
• Targets DSH Web: the client uses the Web slot system (dsh.client.platform: web)
• Browser API dependency: client uses browser globals (fetch, localStorage, …); no non-browser host support

🤝 Why it deserves a ⭐

• Solves a real pain: anyone running long tasks on DSH has hit the "want to interrupt but can't stop" wall
• Obsessed with detail: silky button animation, auto-growing input, 100 playful phrases — small plugin, polished feel
• Clean & auditable: clear two-half structure, readable and reviewable
• Actively maintained: issues & PRs welcome — roadmap includes an always-visible mode, customizable phrase pools, and multi-session support

If you find it useful, a ⭐ is the best encouragement 🚀
