LoopBoard

The missing UI for Claude Code loops.
Claude Code is the engine.
LoopBoard is the cockpit.
You're still the pilot.

Less prompting. No babysitting. More building.

"I don't prompt Claude anymore. I have loops running that prompt Claude and figure out what to do. My job is to write loops."

— Boris Cherny, creator of Claude Code at Anthropic

LoopBoard is a VSCode extension that turns your workspace .loopboard/ tracker into an interactive board your Claude Code agent loops groom, build, and deliver from — while you keep the only two keys that matter: what gets started, and what gets accepted. Markdown stays the source of truth.

Why LoopBoard?

What you get, at a glance:

• 🗂️ Your TODO.md is the board — markdown stays the source of truth; the UI is a live view, never a second database.
• 🤖 Agents groom, build, and deliver — Groomer and Worker loops collaborate on each task while you hold the only two gates: what starts, what's accepted.
• ⏯️ Press Start, not prompts — spawn model-specific Claude Code loop terminals in one click instead of writing a fresh prompt per task.
• 🧩 Multi-model slots — assign Opus / Sonnet / Fable per task (groom vs. work), each a configurable slot.
• 🔒 Zero runtime dependencies — the extension ships no runtime deps; the webview is vanilla HTML/CSS/JS with a CSP nonce on every script.
• 🧵 Context stays on the task — worklog, feedback, and delivery notes live in tasks/<id>.md, not scattered across chats.

How LoopBoard works

1. Create a task.
2. Start the Groomer and Worker loops.
3. Review the Groomed story.
4. Approve it.
5. Let the Worker build.
6. Answer questions—or chat with Claude when deeper discussion is needed.

That's it.

Get started

Run LoopBoard: Initialize Workspace from the Command Palette (or the board's empty-state button) to scaffold .loopboard/ in your workspace. Click the LoopBoard icon in the activity bar for the sidebar summary, then Open Board (or run LoopBoard: Open Board). Accepted work is archived to .loopboard/DONE.md.

Storage layout

.loopboard/
  TODO.md          slim task index — one entry per active task (id, phase, model, groomer, Q&A)
  DONE.md          accepted tasks, newest first (created lazily on the first acceptance)
  LOOP.md          workflow rules + the loop worker instructions the loops read every pass
  tasks/<id>.md    per-task detail: meta, description, notes, worklog, feedback, delivered
  cache/<id>/      staged image attachments (created on the first attach), see below

The board composes each card from the slim index entry plus its tasks/<id>.md. Every edit re-reads the disk, applies one field-level patch, and writes the whole file back canonically (atomic temp-file + rename) — so humans, the board, and multiple agent loops share it safely. On acceptance the index entry moves to DONE.md while the task file stays in tasks/ as history.

.loopboard/ is gitignored, so anything under it — including staged attachments — is local-only and never committed or shared via git. Attach an image to a task by dragging it onto a card (or the New Story composer) or pasting it from the clipboard — no button, drag-drop/paste only — and it's staged under .loopboard/cache/<id>/, referenced with a markdown link in the task's description (or the specific comment/answer field it was dropped into; drafts carry the link in their raw story text). In the New Story composer, pasting inserts a [name](…) link at the caret and the image stays pending (the draft isn't saved yet) — Save Draft stages the bytes and rewrites the link to the real cache path. Each card lists its staged images in an Attachments area with a × that deletes the file and its link; all remaining staged files are deleted once the task is accepted to DONE.md.

Using the board

The activity-bar sidebar (left) is a read-only, at-a-glance summary — click any row to jump into the board. From top to bottom, it shows:

Attention banner — everything currently waiting on you: tasks in Review plus groomed proposals in New that are ready to promote. Phases — every column (New, Backlog, In Progress, Feedback, Review, Done) with a live task count. Loops — one row per model (Opus, Sonnet, Fable), each with its assigned role, a running-status dot, and ▶ spawn / ↻ recycle / ⏹ stop controls. Settings — opens the extension's configuration.

On the board itself:

• New — tick a task's checkbox to promote it to Backlog.
• Feedback — type an answer under each question; the loop resumes once all are answered.
• Review — read DELIVERED, optionally write review feedback (sends it back), or tick to accept → archived to DONE.md.
• New story composer — write free text and choose the groom/worker models inline; it lands as a DRAFT: the loop grooms into a story.

Edits save on blur/Enter as field patches; if the file changed on disk under your edit, the disk value wins and a toast tells you. The board performs only the two human gates — promote and accept — everything else is a field patch the loops react to on their next pass.

Loop terminals

The ▶ buttons open a plain VSCode terminal named Claude <Model> in the workspace root and run claude --model <m> --permission-mode <cfg> with a tiny bootstrap prompt that points the loop at .loopboard/LOOP.md's Automation section — the standing instructions each loop re-reads every pass. ↻ disposes and respawns for a fresh context. Loops die with the VSCode window; restart is one click, since all state lives in .loopboard/.

Settings

Setting	Default	Meaning
loopBoard.defaultWorkerModel	sonnet	model that works tasks with no model: field
loopBoard.defaultGroomerModel	opus	model that grooms tasks/drafts with no groomer: field
loopBoard.permissionMode	auto	--permission-mode passed to the claude CLI
loopBoard.loopInterval	1m	interval passed to the injected /loop line
loopBoard.autoRecycle	false	restart a model's terminal after it finishes a task (fresh context)
loopBoard.clearSessionAfterTask	false	lighter alternative — send /clear after a task instead of restarting
loopBoard.models.<slot>	—	per-slot overrides: .enabled, .model, .effort (see below)

See FAQ.md for common questions (e.g. why there's no Haiku slot).

Configuring models (loopBoard.models.<slot>)

The built-in model slots — opus, sonnet, fable — are what you assign to tasks (model: / groomer:) and what the sidebar Loops rows spawn. Each slot is configured through three keys:

• loopBoard.models.<slot>.enabled — show/hide the slot in the Loops overview and the board's model selects.
• loopBoard.models.<slot>.model — the actual string passed as claude --model <string> (e.g. opus[1m] or a dated snapshot). Empty falls back to the slot's built-in default; anything outside [A-Za-z0-9._\[\]-] is rejected before it reaches the terminal.
• loopBoard.models.<slot>.effort — grooming-subagent reasoning-effort ceiling (low…max) for that slot, per Rule 14 in LOOP.md.

// Pin Opus to a dated snapshot; run Sonnet with the 1M-context window; hide Fable.
"loopBoard.models.opus.model": "claude-opus-4-8",
"loopBoard.models.sonnet.model": "sonnet[1m]",
"loopBoard.models.fable.enabled": false

Migrating from "Claude TODO Board" (≤ 0.1.1): the extension, command, and settings ids were renamed from claudeTodo.* to loopBoard.* with no fallback — re-enter any custom settings.json values under the new keys.

Build & contribute (Docker only)

Node and every other tool run inside Docker — nothing is installed on the host, which needs only Docker, make, git, and VSCode. Open the folder in VSCode and press F5 to launch the Extension Development Host against this repo's own .loopboard/ tracker. All toolchain commands are wrapped in the Makefile:

make install    # npm install (typescript + @types/vscode only) in node:22
make build      # tsc -> out/
make test       # compile pure modules + run node --test round-trip / merge suites
make package    # build a .vsix via @vscode/vsce

Zero runtime dependencies; the webview is vanilla HTML/CSS/JS with a CSP nonce on every script.

Security model

Treat .loopboard/ and workspace settings as trusted input. LoopBoard points an autonomous claude session at .loopboard/LOOP.md's Automation block, running with the configured loopBoard.permissionMode — which may be bypassPermissions. Anything written into LOOP.md (or the task files it opens), or into .vscode/settings.json, steers an agent that can run commands on your machine. This is inherent to what LoopBoard does, not a bug.

• A .loopboard/ from a source you don't control (a cloned repo, a shared workspace) is a prompt-injection vector with arbitrary-command-execution reach.
• Review .loopboard/LOOP.md before starting a loop in a repo you didn't author, and set loopBoard.permissionMode no higher than you're comfortable running unattended.

VSCode Workspace Trust gates activation, but trusting a repo to open it is not the same as vetting what its .loopboard/ will tell an agent to do.

Usage volume

Advertised usage limits for Pro and Max plans assume "ordinary, individual usage of Claude Code and the Agent SDK." A tight loop (the default is 1m) spinning multiple model terminals unattended around the clock can push past that, and Anthropic may rate-limit or enforce against the account. LoopBoard drives your own locally-authenticated Claude Code CLI — nothing here is against the ToS, but its design encourages high-frequency multi-model looping, so it's worth being aware of.
