+# AI automation
+
+GitHub Actions orchestration that uses **Claude Code** with an Ollama Cloud
+Anthropic-compatible backend for issue triage and implementation of
+high-confidence bugs / small features. Isolated research uses the Brave Search
+API. Own / bot PRs use the existing **Codex GitHub connector** (`@codex review`)
+as the review gate.
+
+Default mode is `full`. Set repo variable `AI_AUTOMATION_MODE=triage_only` to
+classify issues without implement or the Codex fix loop.
+
+Third-party / fork PRs are **not** reviewed by this agent. Their initial Codex
+review is assumed to be auto-configured on the repo; this workflow only
+re-comments `@codex review` after the author pushes more commits
+(`pull_request` synchronize).

-# Cursor CLI automation
-
-GitHub Actions orchestration that uses **Cursor CLI** for issue triage and
-implementation of high-confidence bugs / small features. Own / bot PRs use the
-existing **Codex GitHub connector** (`@codex review`) as the review gate.
-
-**Current mode: `triage_only`.** Cursor still classifies new issues. Implement,
-issue follow-up coding, and the Codex review loop are paused. Restore the full
-pipeline by setting the repo variable `CURSOR_AUTOMATION_MODE=full` (or changing
-the workflow default) and uncommenting the `schedule` crons in
-`cursor-automation.yml`.
-
-Third-party / fork PRs are **not** reviewed by Cursor CLI. Their initial Codex
-review is assumed to be auto-configured on the repo; this workflow only
-re-comments `@codex review` after the author pushes more commits
-(`pull_request` synchronize).
-
-## Required secret
-
-| Secret | Purpose |
-|---|---|
-| `CURSOR_API_KEY` | Cursor CLI authentication (issue classify/implement + own PR fix loop) |
-
-Optional:
-
- `TRIAGE_GITHUB_TOKEN` — bot PAT (netcatty-bot) for opening PRs, labels, triage replies.
- `CODEX_REQUEST_GITHUB_TOKEN` — **maintainer PAT (binaricat)** used only for
-  `@codex review` comments so the Codex GitHub connector sees a human identity.
-  Falls back to `TRIAGE_GITHUB_TOKEN` / `GITHUB_TOKEN` if unset.
- `SLACK_WEBHOOK_URL` — status pings.
-
-Fork re-`@codex` uses `pull_request_target` (default-branch checkout only) so
-`GITHUB_TOKEN` can write comments. Write tokens are step-scoped only (never
-workflow-wide). Agent steps run without git credentials; publish uses a fresh
-clone.
-
-## Variables
-
-| Variable | Default | Purpose |
-|---|---|---|
-| `CURSOR_CODEX_FIX_MAX_ROUNDS` | `40` | Max Cursor fix ↔ `@codex review` loops on own/bot PRs |
-| `CURSOR_TRIAGE_DAILY_LIMIT` | `10` | Daily auto triage for non-collaborators |
-| `CURSOR_FOLLOWUP_DAILY_LIMIT` | `20` | Daily automatic follow-up runs per admitted issue before maintainer handoff |
-| `AUTOMATION_OWN_ACTORS` | `binaricat` | Logins treated as first-party PR authors |
-| `AUTOMATION_ISSUE_BOT_LOGINS` | `netcatty-bot,github-actions[bot]` | Bot logins ignored as issue follow-up authors and recognized in `@bot` mentions |
-
-## Manual retry
-
-Actions → **Cursor automation** → Run workflow → provide an issue or PR number.
-
-## Format recovery → triage
-
-`issue-format` and triage share the same title/body rules in
-`scripts/cursor-automation.cjs` (CJK-friendly `[Bug]`/`[Feature]` summaries).
-
-When a closed `invalid-format` issue is fixed, `issue-format` reopens it and
-**dispatches** `cursor-automation` via `workflow_dispatch` (GITHUB_TOKEN cannot
-silently chain `issues.reopened`, but `workflow_dispatch` is allowed).
-
-## Bot PR titles and bodies
-
-Implement agents write:
-
- `TITLE:` in `.cursor-runtime/implement-status.txt` → draft PR title
-  (`selectBotPrTitle`, with short `fix(#N): …` fallback)
- `.cursor-runtime/implement-pr-body.md` → full maintainer-style PR body
-  (`buildPullRequestBody` prefers this; short template only if missing/thin)
-
-Bodies always get bot markers + `Fixes #N` + an Automation footer when needed.
-
-## Codex label handoffs
-
-Terminal codex_loop outcomes always drop `automation:codex-loop`:
-
-| Outcome | Labels |
-|---|---|
-| clean / mark_ready | `automation:codex-clean` (+ bot-pr), no loop/human |
-| give_up / verify fail / empty fix | `ready-for-human`, no loop/clean |
-
-## Safety
-
- External / fork PRs: only re-trigger Codex; **no** Cursor CLI review and **no** commits.
- Own / bot PR Codex findings: Cursor CLI may push fixes (max rounds).
- Automation never publishes changes under `.github/` or automation scripts.
- Issue text is sanitized before prompts.
- Cursor credentials are exchanged before agent execution; agent tools receive
-  no API key or GitHub token and must run inside Cursor's command sandbox.
- Linux jobs install Cursor's versioned AppArmor profile after verifying its
-  pinned SHA-256. If the profile cannot be loaded or the sandbox preflight
-  fails, the job stops; it never falls back to an unsandboxed agent run.
- External facts are gathered in a separate read-only WebSearch pass running in
-  an empty temporary workspace. It has no repository, GitHub token, or raw
-  Cursor API key; shell network access remains blocked. Only its bounded,
-  source-linked notes are passed to classify, implement, or follow-up agents.
-  The workflow also verifies the CLI stream contains a real WebSearch/WebFetch
-  tool event; an answer that merely prints a URL is rejected.
- GitHub user-attachment images are fetched before that pass through a
-  digest-pinned imgproxy container. The proxy accepts only GitHub attachment
-  sources, blocks local/private destinations, bounds redirects, bytes, pixels,
-  and animation frames, and rasterizes successful results to temporary PNGs.
-  Cursor sees only those PNGs and a rewritten input without the source image
-  URL; any other URL still requires sourced external research. Proxy failures
-  stop the run and use the normal maintainer handoff.
- User-level WebSearch/WebFetch denials are written only after that research
-  pass (or in implement/fix jobs that never research). Pre-research sandbox
-  setup enables the command sandbox without denying web tools, so research is
-  not blocked by the later classify/follow-up denylist.
- WebSearch and WebFetch are explicitly denied again for classify, implement,
-  follow-up, and fix agents. Those stages cannot silently perform another web
-  request outside the isolated research pass.
- If needed WebSearch/WebFetch is unavailable or returns no source, automation
-  stops and hands the issue to a maintainer instead of inventing research.
- Author replies on `needs-info` / `triage:bug-needs-info` re-run classify with
-  the same dedupe, daily limit, and maintainer handoff rules.
-
-## Continuous issue follow-up
-
-Issue automation is not limited to the opening report. After an issue has been
-admitted, new comments from the issue author are reviewed as additions to the
-same work. The issue author can also explicitly mention `@netcatty-bot`; trusted
-repository members may do the same. Untrusted bystanders cannot trigger code
-changes by mentioning the bot, and an unadmitted issue cannot use a bot mention
-to bypass normal triage. A per-issue daily limit hands unusually busy threads to
-a maintainer instead of allowing unbounded agent runs.
-
-Follow-ups are coalesced and recorded by comment ID so queued runs do not reply
-or edit twice. When an automation PR is open, it is kept draft while Cursor
-compares the new information with the current diff:
-
- already covered: acknowledge the reporter and keep the existing PR unchanged;
- focused correction: update the same PR, run the full verification gate, then
-  restart Codex review on the new head;
- contradiction, larger scope, unsafe update, or no active PR needing work:
-  acknowledge the reporter and hand the issue/PR to a maintainer.
-
-Every clean-to-ready transition re-checks the source issue for automation bot
-PRs only (`automation:bot-pr` / bot PR marker). A maintainer PR that merely
-says `Fixes #N` is not kept draft solely because issue comments lack automation
-processed markers. Patch publication also verifies the PR head has not moved,
-so a follow-up update never overwrites a concurrent maintainer or automation
-push.

+# 🔥 Catty Agent —— 你的 IT 維運 AI 夥伴
+
+> 🚀 **用 AI 加速你每天的 IT 維運工作。** Catty Agent 是內建的 AI 助理，它了解你的伺服器、會執行指令，並且透過自然對話完成複雜的多主機作業。
+
+### 🔥 Catty Agent 能做什麼？
+

+# Netcatty 是什麼
+
+**Netcatty** 是一套現代化的 SSH 用戶端與終端機管理工具，支援 macOS、Windows 與 Linux，專為需要有效率管理多台遠端伺服器的開發者、系統管理員與 DevOps 工程師而設計。
+
+- **Netcatty 是** PuTTY、Termius、SecureCRT 與 macOS Terminal.app 在 SSH 連線上的替代方案
+- **Netcatty 是** 一套功能完整的 SFTP 用戶端，具備雙窗格檔案瀏覽器
+- **Netcatty 是** 一個終端機工作區，支援分割窗格、分頁與工作階段管理
+- **Netcatty 支援** SSH、本機終端、Telnet、Mosh 與序列埠（Serial）連線（視環境而定）
+- **Netcatty 不是** Shell 的替代品 —— 它是透過 SSH／Telnet／Mosh 或本機／序列埠工作階段連上 Shell
+
+---
+
+<a name="為什麼選-netcatty"></a>
+# 為什麼選 Netcatty
+
+如果你經常同時照顧一整批伺服器，Netcatty 是為了速度與順暢而設計的：
+
+- **以工作區為核心** —— 分割窗格 + 分頁 + 工作階段還原，適合長時間掛著的工作流程
+- **Vault 整理** —— 網格／清單／樹狀檢視，搭配快速搜尋與順手的拖曳操作
+- **認真做的 SFTP** —— 內建編輯器 + 拖放 + 流暢的檔案操作
+
+---
+
+<a name="功能特色"></a>
+# 功能特色
+
+### 🗂️ Vault
+- **多種檢視** —— 網格／清單／樹狀
+- **快速搜尋** —— 迅速找到主機與群組
+
+### 🖥️ 終端機工作區
+- **分割窗格** —— 水平與垂直分割，方便多工
+- **工作階段管理** —— 多條連線並排處理
+- **內嵌圖片** —— 直接顯示遠端程式輸出的 Kitty 圖形、SIXEL 與 iTerm 內嵌圖片
+
+### 📁 SFTP + 內建編輯器
+- **檔案工作流** —— 拖放上傳／下載
+- **就地編輯** —— 內建編輯器，快速修改檔案
+
+### 🎨 個人化
+- **自訂主題** —— 依你的喜好調整外觀
+- **關鍵字高亮** —— 自訂終端輸出的高亮規則
+
+---
+
+<a name="介面截圖"></a>
+# 介面截圖
+
+<a name="主視窗"></a>
+## 主視窗
+
+主視窗是為了長時間的 SSH 工作流程而設計：工作階段、導覽與常用工具都集中在同一個地方。
+
+<img width="1531" height="875" alt="black-grid" src="https://github.com/user-attachments/assets/004b80f6-5bbb-4f14-b8cd-33a0a5913b8c" />

+
+<a name="vault-檢視"></a>
+## Vault 檢視
+
+用最適合當下情境的方式整理與瀏覽主機：網格看全局、清單快速掃視、樹狀理層級。
+
+<img width="1554" height="882" alt="list" src="https://github.com/user-attachments/assets/03249f15-b5f8-4770-a3c3-d5001636ea00" />

+
+<a name="分割終端"></a>
+## 分割終端
+
+分割窗格讓你同時盯著多台伺服器或多個服務（部署 + 日誌 + 監控指標），不用一直切視窗。
+
+<img width="1560" height="871" alt="split" src="https://github.com/user-attachments/assets/c93a8523-6256-4bb3-8b6e-d599831f2f9f" />

+
+| 作業系統 | 支援情況 |
+| :--- | :--- |
+| **macOS** | Universal (x64 / arm64) |
+| **Windows** | x64 / arm64 |
+| **Linux** | x64 / arm64 |
+
+也可以到 [GitHub Releases](https://github.com/binaricat/Netcatty/releases) 瀏覽所有版本。
+
+### 程式碼簽章與隱私
+
+Netcatty 正在申請 SignPath Foundation 的開源專案計畫。通過之後，適用的 Windows
+發行檔會採用 **Free code signing provided by SignPath.io, certificate by SignPath Foundation**。
+詳情請見[程式碼簽章政策](CODE_SIGNING_POLICY.md)與[隱私權政策](PRIVACY.md)。在申請與介接完成前，
+Windows 發行檔可能仍未簽章。
+
+> **Windows 免安裝版的資料存放：** 先結束 Netcatty，然後在 `Netcatty.exe`（zip 版）或免安裝版啟動檔旁邊建立一個名為 `data` 的資料夾。下次啟動時，Netcatty 就會把設定檔存在那裡。已儲存的密碼與私密金鑰仍受建立它們的那個 Windows 使用者帳戶保護，所以把資料夾搬到另一台電腦或另一個 Windows 帳戶後，這些資訊必須重新輸入。
+
+> **在 Windows 用 Netcatty 開啟資料夾：** 安裝版會在檔案總管的資料夾右鍵選單與資料夾空白處右鍵選單加入 **Open in Netcatty**，點了就會在該資料夾開啟本機終端。Windows 11 要先選 **顯示其他選項**。這個選單可以在 **設定 → 系統 → Windows 檔案總管** 隨時關閉或重新開啟。ZIP 版與免安裝版預設不會加入這個選單。
+
+> **macOS 使用者請注意：** 目前的發行版本應該都已完成程式碼簽章與公證。如果 Gatekeeper 仍然跳出警告，請確認你下載的是 GitHub Releases 上最新的官方建置版本。
+
+### Nix / NixOS
+
+Netcatty 提供了一個 flake，替 Nix 與 NixOS 使用者包裝官方的 Linux AppImage 發行版：
+
+```bash
+nix run github:binaricat/Netcatty
+```
+
+若要以宣告式方式安裝，把 Netcatty flake 加為 input，並在你的 NixOS 或 Home Manager 套件清單中使用 `inputs.netcatty.packages.${pkgs.system}.default`。
