I was the relay between the planner and the executor, and quality slipped the moment I stopped watching. I wanted the handoff automated and my standards enforced without me in the middle. ### What it does AgentLoop is a local orchestration daemon for coding agents. It is built for solo developers running long Codex tasks without babysitting every session. You plan a goal in ChatGPT, and a custom MCP connector sends it to a daemon on your machine. Each cycle starts a fresh Codex worker with a clean context. Work carries forward in project files, not chat history. After every worker, a fresh critic grades the result against your rubric in GUIDELINES.md and turns failures into concrete fix notes for the next worker. Every worker and critic uses workspace-write sandboxing, disables network access inside the sandbox, and routes boundary requests through automatic approval review. Polish mode keeps improving past the first PASS until the critic verdicts SHIP. The whole run is watchable and cancellable on a local dashboard. How I built it The architecture and product decisions are mine: the sequential fresh-context design, the files-as-memory model, the strict critic verdict contract, the rubric-as-GUIDELINES pattern, and the scope calls on what shipped versus what stayed on the roadmap. Codex CLI with GPT-5.6 turned those decisions into working code: the daemon, filesystem store, loop engine, critic, bridge, and dashboard were each built in focused Codex sessions, roughly one slice per session. The workflow: plan in ChatGPT, execute in Codex sessions, review rounds with automated Codex reviewers, then forward-fix commits. The result is zero-dependency plain Node.js. Task state, transcripts, and events are JSON and NDJSON files. The dashboard is one local HTML file. AgentLoop then runs Codex CLI as both its worker and critic engine. Codex built a tool that drives Codex. Challenges I ran into Context rot: long chats collect stale assumptions, so every worker and critic is a fresh process and the files are the memory. Critic reliability: vague rubrics made verdicts thrash, so the critic contract requires the final line to be exactly VERDICT: PASS or VERDICT: FAIL with concrete fixes. Process control on Windows: spawning, timeouts, and cancellation of CLI sessions took real care. Securing the bridge: loopback-only ports, token auth, and a tunnel for the hosted connector. Accomplishments that I'm proud of The full chain works end to end: ChatGPT sends a goal, the daemon loops fresh workers, the critic enforces the rubric, and shipped code lands on my machine with no human relay. The demo run is real: cycle one fails, the critic writes the fix list, cycle two passes, and polish mode ships it on cycle three. In a separate evaluation with no forced failure, cycle one produced nine passing tests, but the fresh critic found a mixed percent-decoding defect; cycle two fixed it, added regression coverage, passed 11 tests, and received PASS. All with zero package dependencies. What I learned Standards belong in files, not prompts. A rubric the critic reads every cycle beats instructions a human repeats every session. Fresh context beats long chats for unattended work. And observability builds trust: a loop you can watch is a loop you can leave alone. ### What's next Research loops that gather sources before writing against a rubric. Two-way messages so the dashboard can answer agent questions. And more engines: the engine layer is pluggable, Codex ships first. ## README (from the GitHub repository) # AgentLoop Self-improving fresh-context loops for coding work you can watch. ![AgentLoop dashboard showing a worker and critic loop](docs/dashboard.png) [Watch the demo](https://youtu.be/4zRdMMzh3C8) | [Try the replay](https://agentloop-replay.vercel.app) - a real recorded run in the live dashboard ## What it is Plan a goal in Claude or ChatGPT, then let it rip. AgentLoop is a local orchestration daemon for coding agents: each cycle starts a fresh worker, work carries forward in project files, a fresh critic enforces your rubric, and the whole run is watchable on a local dashboard. Codex CLI and Claude Code both run as engines. Pick one per loop from the dashboard, or per task through the bridge. AgentLoop is for solo developers who run long agent tasks across multiple projects and cannot supervise every session. It exists because running coding agents by hand means shuttling plans between a chat and a terminal all day, and quality slips the moment you stop watching. Your standards live in GUIDELINES.md and the critic enforces them every cycle, so you supervise the work without babysitting it. ## Why sequential fresh-context Long-running chats collect stale assumptions and irrelevant context. That is context rot. AgentLoop starts a new engine process for every worker and critic session, so no prior chat history follows them. The durable context is the project itself plus concrete critic fixes. That keeps a loop bounded, easier to leave unattended, and less likely to spend tokens re-reading an ever-growing conversation. A loop is intentionally sequential. Independent queued tasks can run up to `maxConcurrent`, but one loop does not create a parallel swarm that races across the same project. ```text Claude or ChatGPT -> MCP bridge -> daemon -> worker/critic cycles -> dashboard ``` ## How it works - **Dispatch** sends one one-shot task to `POST /api/dispatch`. Its file moves from pending to running to done, with a transcript and dashboard cancellation. - **Loop** runs a project cycle by cycle. A worker reads `PLAN.md` and `STATE.md`, makes one increment, updates state, and exits. A fresh critic then reads `PLAN.md`, `GUIDELINES.md`, the worker output, and the project files. The next worker is a new process. - **Polish mode** is an optional loop flag: after the first PASS, remaining cycles become polish cycles where the critic re-verifies the guidelines and proposes one improvement per cycle until it verdicts SHIP. - **Critic contract** requires the final line to be exactly `VERDICT: PASS`, `VERDICT: FAIL - `, or `VERDICT: CONTINUE - done: ; next: `. FAIL becomes injected fix notes for the next worker; CONTINUE records a finished PLAN.md item and starts a fresh worker on the next one; PASS means every unblocked plan item is complete and ends the loop unless polish mode is on. Polish cycles end with `VERDICT: IMPROVE - ` or `VERDICT: SHIP`. `maxCycles` is capped at 1 to 50 and defaults to 3. - **Stuck tasks get skipped.** `taskRetries` (1 to 10, default 3) caps consecutive FAIL cycles per task; at the cap the task is marked blocked, later workers and critics skip it, and the loop ends `partial` if the rest passes or `incomplete` if the cycle budget runs out mid-plan. - **Auto-checkpoint** is on by default for projects inside a git work tree: the daemon makes a local commit after each completed task, on the final pass, and when a task is blocked. The daemon composes every commit message itself and never touches remotes; a dirty tree at loop start is refused so checkpoints stay clean. - **Files are memory.** `PLAN.md`, `STATE.md`, and `GUIDELINES.md` carry the goal, progress, and rubric. A loop project needs `PLAN.md`; missing `STATE.md` and `GUIDELINES.md` files are seeded automatically. - **Messages narrate a run.** A connected chat client can post `info`, `question`, or `results` messages through the bridge. They appear in the dashboard Messages panel. - **Engines are pluggable.** `src/engines.js` holds one entry per engine: how to find its CLI, what arguments to run it with, and how to read its event stream. The daemon itself is engine-agnostic. Set `defaultEngine` in `config.json`, override it per loop in the dashboard, or per task through the bridge. An engine that is not installed is greyed out rather than offered. - **Workers start clean and constrained.** Codex sessions use workspace-write sandboxing, disable network access inside the sandbox, and route boundary requests through automatic approval review. Claude Code sessions run with `acceptEdits` so they never block on a prompt, `--safe-mode` so a worker ignores your personal `CLAUDE.md`, hooks, skills, and MCP servers, and web tools disabled. The two are not identical: Codex isolates the network at the sandbox boundary, so a shell command it runs cannot reach out, while a shell command run by Claude Code can. The daemon is plain Node with no package dependencies. Task state, results, transcripts, events, and messages are stored as JSON or NDJSON files. The dashboard is one local HTML file at `http://127.0.0.1:5757`. ## Multi-task loops A `PLAN.md` written as a top-level list is walked one item per worker: ```markdown # Calculator Users report two bugs in `calculator.html`. 1. Fix the arithmetic. 2. Fix the `%` button. ``` `-`, `*`, `+`, and `1.` all count, up to 100 items. Indented lines are detail for the item above them, not items of their own. Each cycle takes one item. `VERDICT: CONTINUE - done: ; next: ` closes that item and starts a fresh worker on the next one. `VERDICT: FAIL` keeps the same item and injects the critic fixes into the next worker. `VERDICT: PASS` ends the loop once every unblocked item is complete. `taskRetries` caps consecutive FAIL cycles on a single item, 1 to 10, default 3. At the cap that item is marked blocked: later workers take the next item instead, the critic stops grading it, and the loop finishes `partial` if the rest passes or `incomplete` if the cycle budget runs out first. Size `maxCycles` at roughly tasks x retries. ### Checkpoints Auto-checkpoint is on by default for a project inside a git work tree. The daemon commits after each completed item, when an item is blocked, and on the final pass, so every task boundary is a sha you can read, diff, or reset to. The dashboard shows each one on its task chip. The daemon writes those commit messages itself from the verdict text. Agents never run git, and the daemon never touches a remote: `git add -A .` then `git commit` inside the project folder, nothing else. It needs two things. The project must be a git work tree, otherwise the toggle is forced off and the dashboard reads `checkpoints off`. And the project tree must be clean when the loop starts, otherwise the loop is refused, so a checkpoint only ever holds work the loop did. ## The dashboard A left rail navigates the page - waiting on you, active run, recent runs, queue, messages, event log - and holds the loop launcher, live daemon status, and a theme picker with fifteen editor themes remembered locally. - **Cycle timeline.** The active run shows one card per cycle: verdict, critic summary, duration, and cost. A card working a plan task carries a try tag like `T02 · try 1/3`, and a task that hits its retry budget is marked blocked on the card itself. - **Task rail.** A loop with a parsed `PLAN.md` gets a chip per plan task: done chips show their checkpoint sha, the active chip shows its try count, blocked chips show the spent retry budget. - **Waiting on you.** Tasks blocked on an answer pin to the top of the page with a rail badge; the block stays hidden while nothing is blocked. - **End states.** Recent runs keep loop endings distinct: `passed`, `partial` (passed with blocked tasks), `incomplete` (cycle budget ran out mid-plan), and `maxed` (no passing verdict), plus counts of tasks done and blocked. - **Launcher.** The loop form takes a project folder, max cycles, [README truncated for size] ## Detected evidence (automated analysis) Indexed codebase: 20 recognized source files, 296 KB. - HTML (language) — detected in the code - JavaScript (language) — detected in the code - CSS (language) — claimed on Devpost, not found in the code - Node.js (technology) — claimed on Devpost, not found in the code - OpenAI (technology) — claimed on Devpost, not found in the code ## Codebase structure (from repository index) ### Files (26 of 26) ``` .gitignore bridge.js config.json docs/evaluation.md examples/calculator/calculator.html examples/calculator/GUIDELINES.md examples/calculator/PLAN.md examples/query-parser/GUIDELINES.md examples/query-parser/PLAN.md examples/query-parser/query-string.js examples/query-parser/STATE.md examples/starter/GUIDELINES.md examples/starter/PLAN.md examples/starter/STATE.md LICENSE package.json public/index.html README.md replay/data/log-t-bc53c776.json replay/data/run.json replay/index.html replay/replay.js src/daemon.js src/prompts.js src/store.js test/sandbox.test.js ``` ### Dependencies No dependency index available. ### Recent commits (newest first) - fix: sandbox worker sessions (#14) - docs: expand Codex collaboration section with design context (#13) - fix: mobile usability pass on replay (#12) - feat: add static replay demo of a recorded run (#11) - docs: update tagline (#10) - docs: refresh README hero screenshot (#9) - feat: show tunnel public url in connector popover (#8) - feat: add polish mode to the loop engine (#7) - feat: add calculator demo example (#6) - feat: add live messages panel - feat: add MCP bridge - feat: add loop engine with critic - feat: add task dashboard - fix: harden events feed and cancel event kind - fix: populate events feed and normalize timeout summary - fix: prefer timeout reason over earlier input failure - fix: address dashboard review feedback - feat: add dashboard control api - feat: replace dashboard design - feat: add dashboard ui ## Key source files (fetched from GitHub, selected and truncated for size) ### docs/evaluation.md ```markdown # Independent evaluation AgentLoop ran the reproducible [query parser fixture](../examples/query-parser) with three cycles available and polish disabled. The [plan](../examples/query-parser/PLAN.md) requested the complete repair in one pass and prohibited artificial cycle boundaries. The [guidelines](../examples/query-parser/GUIDELINES.md) defined ten acceptance criteria. The committed fixture is the pre-run starting state. A reproduction run repairs that working copy, adds tests, and updates `STATE.md`. | Cycle | Worker result | Independent critic result | | --- | --- | --- | | 1 | Repaired the parser and added nine passing tests. | `FAIL`: valid percent escapes remained encoded when a field also contained malformed escapes. | | 2 | Fixed tolerant decoding and added regression coverage. | `PASS`: all criteria were satisfied and 11 tests passed. | The first worker's own suite passed. A fresh critic tested beyond it, found a real defect, and converted the finding into instructions for the next fresh worker. No package dependencies were added. ## Reproduce 1. Start the daemon and select **+ New**, then **Loop**. 2. Set **Project** to `examples/query-parser` and **Max cycles** to `3`. 3. Leave polish disabled and select **Start loop**. ``` ### examples/query-parser/STATE.md ```markdown # State ## Completed - Nothing yet. ## Next - Repair the query parser and verify it. ## Notes - No critic feedback yet. ``` ### package.json ``` { "name": "agentloop", "version": "0.1.0", "private": true, "description": "Sequential fresh-context agent orchestrator", "scripts": { "test": "node test/sandbox.test.js" }, "engines": { "node": ">=18" } } ``` ### bridge.js ```javascript const http = require('node:http'); const crypto = require('node:crypto'); const fs = require('node:fs'); const path = require('node:path'); const root = __dirname; const statePath = path.join(root, 'state'); const logsPath = path.join(statePath, 'logs'); const configPath = path.join(root, 'config.json'); const heartbeatPath = path.join(statePath, 'bridge.json'); const tokenPath = path.join(statePath, 'mcp-token'); const protocolVersion = '2025-06-18'; const supportedVersions = new Set(['2024-11-05', '2025-03-26', protocolVersion]); const maxBodyBytes = 1000000; let bridgeToken; let heartbeatTimer; let server; let startedAt; let shuttingDown = false; function loadConfig() { try { return JSON.parse(fs.readFileSync(configPath, 'utf8')); } catch { return {}; } } function bridgePort() { const port = Number(loadConfig().mcpBridge?.port); return Number.isInteger(port) && port >= 1024 && port <= 65535 ? port : 5758; } function dashboardPort() { const port = Number(loadConfig().dashboardPort); return Number.isInteger(port) && port > 0 && port < 65536 ? port : 5757; } function log(message) { try { fs.mkdirSync(logsPath, { recursive: true }); fs.appendFileSync(path.join(logsPath, 'bridge.log'), `${new Date().toISOString()} ${message}\n`, 'utf8'); } catch { } } function storedToken() { try { return fs.readFileSync(tokenPath, 'utf8').trim(); } catch { return ''; } } function readToken() { while (true) { const existing = storedToken(); if (existing) { return existing; } try { fs.unlinkSync(tokenPath); } catch (error) { if (error.code !== 'ENOENT') { throw error; } } const token = crypto.randomBytes(32).toString('hex'); fs.mkdirSync(statePath, { recursive: true }); try { fs.writeFileSync(tokenPath, `${token}\n`, { encoding: 'utf8', flag: 'wx', mode: 0o600 }); return token; } catch (error) { if (error.code !== 'EEXIST') { throw error; } } } } function writeHeartbeat() { fs.mkdirSync(statePath, { recursive: true }); fs.writeFileSync(heartbeatPath, `${JSON.stringify({ pid: process.pid, port: bridgePort(), startedAt, ts: new Date().toISOString(), }, null, 2)}\n`, 'utf8'); } function clearHeartbeat() { try { const heartbeat = JSON.parse(fs.readFileSync(heartbeatPath, 'utf8')); if (heartbeat.pid !== process.pid) { return; } } catch { } try { fs.unlinkSync(heartbeatPath); } catch { } } function sendJson(res, statusCode, value) { const body = JSON.stringify(value); res.writeHead(statusCode, { 'cache-control': 'no-store', 'content-type': 'application/json; charset=utf-8', 'content-length': Buffer.byteLength(body), }); res.end(body); } function sendEmpty(res, statusCode, headers = {}) { res.writeHead(statusCode, { 'cache-control': 'no-store', ...headers }); res.end(); } function readJsonBody(req) { return new Promise((resolve, reject) => { let size = 0; let body = ''; req.setEncoding('utf8'); req.on('data', (chunk) => { size += Buffer.byteLength(chunk); if (size > maxBodyBytes) { reject(new Error('Request body is too large.')); req.destroy(); return; } body += chunk; }); req.on('end', () => { try { resolve(JSON.parse(body)); } catch { reject(new Error('Request body must be valid JSON.')); } }); req.on('error', reject); }); } function rpcResult(id, result) { return { jsonrpc: '2.0', id, result }; } function rpcError(id, code, message) { return { jsonrpc: '2.0', id, error: { code, message } }; } function timingSafeEqual(left, right) { if (!left || !right) { return false; } const leftBuffer = Buffer.from(left); const rightBuffer = Buffer.from(right); return leftBuffer.length === rightBuffer.length && crypto.timingSafeEqual(leftBuffer, rightBuffer); } function authorized(req, requestUrl) { const header = req.headers.authorization; const match = typeof header === 'string' ? /^Bearer\s+(.+)$/i.exec(header) : null; const candidate = match ? match[1].trim() : requestUrl.searchParams.get('key') || ''; if (!candidate || !bridgeToken) { return false; } return timingSafeEqual(candidate, bridgeToken); } function daemonRequest(requestPath, body) { return new Promise((resolve, reject) => { const data = body === undefined ? null : Buffer.from(JSON.stringify(body)); const request = http.request({ hostname: '127.0.0.1', port: dashboardPort(), path: requestPath, method: data ?
