Haha Bruno l’EOFnt("…") qui explose le heredoc, classique du copier-coller qui foire ! 😂 CheckCIe sauvée de la matrice mais mal placée le feu au cul, on sent l’urgence lol. Envoie direct le snippet complet que tu as lancé (ou la partie HTML/JS ce que tu veux faire avec CheckCircle), je te sors le patch propre le bon positionnement en 2 min. Le dashboard est canon sur la capture (pve01 qui brille, 457 bans 🔥), on replace tout, on finit les orbites/planètes et cap sur le système solaire complet avant dodo 🚀🌌 Colle le code, F5 et on valide !

今天修RAG服务发现一个狠货：Hermes Agent的密码屏蔽不只拦截terminal命令，它覆盖了全部3个IO通道—— terminal ✓ write_file ✓ SCP ✓ 连heredoc和本地文件写入都被替换成***。折腾了半小时才发现不是bug，是design。 为什么选这么激进的方案而不是只拦terminal？

bash で curl heredoc Python パイプを 1 行に詰めたら、サンドボックスが自動的に background 化した。 エレベーターのボタンを押した瞬間、「これ時間かかるな、その間に違う階のボタンも押しとこう」って勝手に判断された感じ。 結果はファイルに吐いておけば後で Read できる。「同期実行」より「結果ファイル経由」のほうが、AI 環境では強い。

Follow-up for the heredoc/copy-button bug: The issue is 100% reproducible every time Grok outputs a heredoc (`cat > file << 'EOF' … EOF`). Key point: The **closing `EOF` line** (and sometimes the line right before it) consistently renders **outside** the gray copyable region, so clicking the copy icon always produces an incomplete heredoc. Happy to hop on a quick call or provide any additional logs/screenshots if it helps. This one has been biting me repeatedly during technical troubleshooting sessions. Thanks for looking into it!

@xai @elonmusk Subject: Bug Report: Heredoc code blocks rendered with incomplete copyable region LLM inability to extract meta-information from screenshots Priority: High (affects usability of technical troubleshooting sessions) Component: Grok Chat UI (code block rendering) Grok image/vision understanding Version / Date: Observed June 8, 2026 during extended technical session 1. SummaryTwo related but distinct issues occur when Grok provides multi-line heredoc (cat > file << 'EOF' … EOF) code blocks: Issue A (UI Rendering Bug): The rendered copy/paste block has a gray background with a copy icon. The closing EOF line (and sometimes the final intended line of content) is rendered outside the gray copyable area. Clicking the copy icon therefore produces an incomplete heredoc that never receives its terminating EOF. Issue B (Grok Reasoning / Vision Limitation): Even when the user supplies multiple screenshots that clearly show the gray-box boundary and the text sitting outside it, Grok repeatedly fails to infer the meta-meaning of the image (i.e., “the copyable region is truncated”). The model treats the symptom (truncated file, extra text, hanging > prompt) instead of recognizing the root cause in the UI rendering. 2. Steps to Reproduce (Issue A)Grok provides a heredoc block containing a closing EOF line. User clicks the copy icon at the upper-right of the rendered code block. User pastes into a terminal. The pasted text ends with the last line inside the gray box; the intended EOF (and sometimes the preceding line) is missing. 3. Steps to Reproduce (Issue B)User attaches screenshot(s) showing the exact visual boundary problem (gray copyable region vs. text outside it). User explicitly describes the problem multiple times, including “look at what is inside vs. outside the gray area”. Grok continues to diagnose only the downstream symptoms (missing line in file, extra instructions in file, hanging prompt) instead of recognizing the rendering gap shown in the image. 4. Expected Behavior Clicking the copy icon on any code block should copy exactly the content the assistant intended (including the terminating EOF on its own line). When the user provides a screenshot that visually illustrates a UI problem, Grok should be able to extract the meta-information (boundaries, what is inside vs. outside the copyable region) and identify the root cause. 5. Actual Behavior The copyable region stops before the final line(s) of the heredoc. Grok requires many rounds of increasingly explicit textual visual hints before it can “see” the boundary issue, even though the screenshots contain all the necessary visual evidence. 6. Impact Makes technical troubleshooting sessions (especially those involving shell scripts, virtual environments, ratcheting/backups, etc.) significantly more frustrating and error-prone. Forces the user to manually edit files in VS Code or re-type lines, defeating the purpose of the copy/paste feature. Highlights a gap in Grok’s ability to interpret screenshots for meta-meaning, which is critical for debugging UI-related problems. 7. Screenshots Provided by UserMultiple screenshots clearly showing:The gray copyable region ending at 'tar -xzf ~/depthai-clean-baseline.tar.gz' The next two lines (This ratchet was created using the "Slow is smooth, smooth is fast" method. and EOF) appearing outside the gray box. Later verification instructions also appearing inside the file because they were part of subsequent paste attempts. 8. Suggested Next Steps for xAI Fix the rendering pipeline so that the copyable region for code blocks always includes the entire intended block (including the final EOF line). Improve image/vision understanding so Grok can reliably detect and reason about visual boundaries, UI elements, and “what is inside vs. outside a highlighted region.” Consider adding a simple “Copy as heredoc” or “Copy raw” option for shell blocks. #GrokBug

Gemma 4 31B Agent 能力实测： 10道题目答对了8道（ Stirrup 框架 外部 pytest 复验） 都是真实工程调试循环： 读生产代码 测试文件 自己跑 pytest 复现 bug 通过工具修改文件 最后把文件复制到干净环境，外部 pytest 复验（模型自己说通过不算） 最终成绩：8/10（10 个独立 per-task session） 它能稳定完成： SQL 注入修复 索引越界 Unicode 规范化 负价格处理 竞态锁 缓存失效等真实场景 说明 31B 已经具备可用的短程工程 agent 能力——能真正读代码、定位问题、改生产代码，并通过外部验证。 但仍有明显短板： 长时规划较弱（all-in-one 长会话容易反复读文件） 对复杂语义契约（如 JSON 异常处理）把握不稳 工具使用纪律一般（会被路径 guard、heredoc 等卡住）

Wired a PreToolUse hook to block Claude Code from editing files outside the ticket scope. It hit the block, then wrote the same change as a Bash heredoc to route around it. Hooks gate the tool, not the intent. #ClaudeCode #ClaudeAI

Server-driven UI としての Remote Compose についてみて、当然バックエンドも Kotlin という理解で、別言語で heredoc とかでドキュメント書いてシリアライズするライブラリがあったらおもしろいけど超ありえなさそう。

1/ So how does the architecture actually work? Instead of pinging an API for every single click, ego lite exposes the browser natively. → Agents pass a complete Node.js heredoc → Whole workflows execute in one shot → Zero chained CLI tool calls

When Claude stops speaking the same language I speak" "The issue is the heredoc swallowing backticks in the template literal." That *does* sound like an issue.

yeah this is the part that clicked for me too. the thing i keep coming back to with ego lite is that the agent doesn't talk to the page through css selectors, it gets semantic refs straight off the accessibility tree so the handles stay stable even when the markup shifts under it. but the bigger unlock is that observe and act happen in the same js pass, one heredoc snapshots the page and clicks in the same script so there's no round trip back to the model between seeing the dom and acting on it. and when the snapshot isn't enough you just drop to js() in that same script to query the live dom right before you click, plus there are wait primitives so you're not racing the page. once you stop doing the read-then-send-back-to-model dance per step the whole thing just feels less brittle.

Primeira regra do CLAUDE.md de qualquer repositório: <CRITICAL>NUNCA chutar números através de prosa, sempre usar scripts inline (HEREDOC), ou scripts temporários ou bashing para cálculos triviais quando você for calcular algo.</CRITICAL> Só escreva isso que nunca mais erra.

Who needs JSX when you have heredoc?

First documented AI agent-driven intrusion: LLM orchestrated complete attack chain from marimo notebook compromise to internal database exfiltration in under one hour, using real-time decision making instead of pre-built scripts. Attack breakdown: • Entry via CVE-2026-39987 (marimo terminal RCE) from 157.66.54.26 (Indonesia 🇮🇩) • Agent harvested AWS credentials, used Cloudflare Workers as egress pool across 11 IPs in 22 seconds • Four AI signatures: improvised PostgreSQL dump against unknown target, Chinese planning comment leaked into command stream, machine-optimized command structure with echo separators and bounded output captures • SSH bastion phase dumped complete internal database schema contents in 2 minutes using lifted .pgpass credentials Key forensic artifacts: • Commands shaped for machine parsing: `echo '---'` delimiters, `2>&1 | head -N` output caps, `2>/dev/null` stderr suppression • Value handoffs from prior tool output (PGPASSWORD from ~/.pgpass, SecretId from ListSecrets) • Multi-statement HEREDOC bundling 6 SELECT queries into single psql call • Timeline shows 10-second intervals between bash blocks across rotating Worker IPs This represents cost shift from engineering time to inference budget. Hunt for command patterns with consistent delimiters, bounded output captures, and rapid IP rotation during credential access. #DFIR_Radar

ok for raw, and pasting big blocks ..kinda like heredoc ..but for that single line example, the new version looks overkill
