* tui: make URLs clickable + hover-highlight in any terminal Problem ------- URLs printed by `hermes --tui` were not clickable in basic macOS Terminal.app. Cmd+click did nothing, the cursor didn't change shape — like nothing was detected — even though arrow buttons and other Box onClick handlers worked fine. Root cause ---------- Two layers of dead plumbing: 1. `<Link>` only emitted the underlying `<ink-link>` (which carries the hyperlink metadata into the screen buffer) when `supportsHyperlinks()` said yes. On Apple_Terminal that's false, so the per-cell hyperlink field stayed empty, so `Ink.getHyperlinkAt()` had nothing to return on click. The visible underline was just decorative. 2. `Ink.openHyperlink()` calls `this.onHyperlinkClick?.(url)`, but `onHyperlinkClick` was never assigned anywhere in the codebase. The click pipeline (`App.tsx → onOpenHyperlink → Ink.openHyperlink`) ran but bailed silently on the optional chain. Bonus discovery: even when wired up, there was no hover affordance — terminal apps can't change the system mouse cursor, so users had no visual signal that a cell was clickable. Arrow buttons in the chrome worked because they had explicit `<Box onClick>` styling; inline link URLs didn't. Fix --- - `Link.tsx`: always emit `<ink-link>` regardless of terminal capability. The renderer's `wrapWithOsc8Link` already gates the actual OSC 8 escape on `supportsHyperlinks()` further down — so terminals that don't understand OSC 8 still don't see the escape, but the screen-buffer metadata (which the click dispatcher reads) is now populated everywhere. - `ink.tsx + root.ts`: add `onHyperlinkClick?: (url: string) => void` to `Options` / `RenderOptions`, wire it to the existing `Ink.onHyperlinkClick` field in the constructor. - `src/lib/openExternalUrl.ts`: small platform-aware opener using `child_process.spawn` with arg-array (no shell) — http(s) only, rejects `file:`, `javascript:`, `data:`, etc., so a hostile model can't trigger arbitrary local handlers via `<Link url="file:///...">`. Detached + stdio ignore so closing the TUI doesn't kill the browser and Chrome stderr doesn't leak into the alt screen. - `entry.tsx`: pass `onHyperlinkClick: openExternalUrl` to `ink.render`. - `hyperlinkHover.ts` + Ink hover wiring: track the URL under the pointer in `Ink.hoveredHyperlink`, update it from `dispatchHover`, and inverse- highlight every cell of the matching link in the render-pass overlay (same pattern as `applySearchHighlight`). This is the cursor-hover affordance for clickable links — terminals don't expose cursor shape, so we light up the link itself. - `types/hermes-ink.d.ts`: add `onHyperlinkClick` to the `RenderOptions` shim so consumers (`entry.tsx`) type-check against the new option. Tests ----- - `src/lib/openExternalUrl.test.ts` (15 cases): http(s) accepted; file/js/ data/mailto/ftp/ssh rejected; macOS open(1), Windows cmd.exe start with empty title slot, Linux xdg-open dispatch; shell-metacharacter URLs pass through unmolested as a single argv element; synchronous spawn failure returns false. Verified empirically in Apple Terminal 455.1 (macOS 15.7.3): clicking a URL opens in default browser, hovering inverts the link cells, and moving away clears the highlight. Full TUI suite: 713 passing, 0 type errors. Reverts ------- The earlier attempt that version-gated Apple_Terminal in `supports-hyperlinks.ts` was based on a wrong assumption — Terminal.app silently strips OSC 8 sequences but does not render them as clickable hyperlinks. Reverted to the original allowlist. * tui: address Copilot review — explorer.exe on win32 + comment fixes - openExternalUrl: switch win32 from `cmd.exe /c start` to `explorer.exe`. cmd.exe's `start` builtin reparses the URL through cmd's tokenizer, so `&`, `|`, `^`, `<`, `>` either split the command or get reinterpreted — breaking both the protocol-allowlist safety story AND plain http(s) URLs with `&` in query strings. `explorer.exe <url>` invokes the registered protocol handler directly with no shell. - openExternalUrl.test.ts: rename the win32 test to reflect the new contract and add two regression tests — one with `&|^<>` metachars, one with the common analytics-URL `&` query-param pattern — both pinned to single-argv-element delivery via explorer.exe. - Link.tsx: fix misleading comment. OSC 8 escapes are emitted unconditionally by the renderer (`wrapWithOsc8Link` in render-node-to-output.ts, `oscLink` in log-update.ts). Non-supporting terminals silently strip the sequence, which is why hover/click affordance has to come from the in-process overlay rather than the terminal's own link rendering. Verified: 715/715 tests pass, type-check + build clean. * tui: address Copilot review #2 — async spawn errors + hover scope + docs 1. openExternalUrl: attach a no-op `'error'` listener on the spawned child BEFORE unref(). spawn() returns a ChildProcess synchronously even when the binary is missing (ENOENT on xdg-open / explorer.exe), unreachable, or otherwise unusable; the failure surfaces later as an 'error' event. An unhandled 'error' on an EventEmitter crashes Node, which would tear down the whole TUI. The listener is a deliberate no-op — we already returned `true` synchronously and the user just doesn't see the browser pop. 2. openExternalUrl.test.ts: add a regression test using a real EventEmitter to simulate the async-error path. Pins both the listener-attached contract and the "doesn't throw on emit" behavior. Was 17/17, now 18/18. 3. ink.tsx dispatchHover: bypass `getHyperlinkAt()` and read `cellAt(...).hyperlink` directly. `getHyperlinkAt` falls back to `findPlainTextUrlAt` for cells without an OSC 8 hyperlink, but the render-pass overlay (`applyHyperlinkHoverHighlight`) only matches on `cell.hyperlink === hoveredUrl` — so plain-text URLs would burn re-renders without ever producing the highlight. Hover is now a strictly 1:1 fit for what the overlay can paint. Plain-text URLs still get the click action via the existing dispatch path. 4. root.ts + ink.tsx doc comments: replace the misleading "typically `open` / `xdg-open` / `start` shell" wording with the actual safe recipe — argv-array spawn into `open` / `xdg-open` / `explorer.exe`, with an explicit warning that `cmd.exe /c start` reparses the URL through cmd's tokenizer and is unsafe + breaks `&`-query URLs. Verified: 716/716 tests pass, type-check + build clean. * tui: address Copilot review #3 — hover damage, alt-screen cleanup, opener allowlist 1. ink.tsx onRender: stop folding steady-state hover into hlActive. hlActive forces a full-screen damage diff so previous-frame inverted cells get re-emitted when the highlight set changes. The transition IS the trigger — enter / leave / change-to-other-link. While the pointer just sits on a link the painted cells don't change and the per-cell diff handles the no-op. Folding the steady state in would burn a full-screen diff on every frame. Added a lastRenderedHoveredHyperlink tracker and gate the hlActive bump on `hovered !== lastRendered`. 2. ink.tsx setAltScreenActive: clear hoveredHyperlink (and the tracker) when toggling alt-screen state. Hover dispatch is alt-screen-gated, so once we leave there's no path to clear it. Without this, remounting <AlternateScreen> would paint a phantom hover from the previous session until the next mouse-move arrived. 3. openExternalUrl.ts openCommand: allowlist linux + the BSD family for xdg-open and return null for everything else (aix, sunos, cygwin, haiku, etc.). Previously the default-fallback always returned xdg-open, which made the caller's `if (!command) return false` dead and yielded a misleading `true` on platforms that probably don't have xdg-open. New tests cover the null path AND the openExternalUrl-returns-false-without-spawning behavior. Verified: 718/718 tests pass, type-check + build clean. * tui: address Copilot review #4 — doc comment accuracy 1. openExternalUrl return-value doc: now lists all three false paths (URL rejected / no opener for platform / synchronous spawn throw) plus a note that async 'error' events still return true because the spawn was attempted. 2. ink.tsx onHyperlinkClick field doc: clarifies the callback receives either an OSC 8 hyperlink OR a plain-text URL detected by findPlainTextUrlAt — App.tsx routes both into the same callback. 3. hyperlinkHover applyHyperlinkHoverHighlight doc: drops the misleading 'caller forces full-frame damage' promise. Caller decides; for hover the current caller only forces full damage on transitions. No behavior change. 718/718 tests pass. * tui: address Copilot review #5 — lint fixes 1. ink.tsx: reorder `./hyperlinkHover.js` import before `./screen.js` to satisfy perfectionist/sort-imports. 2. Link.tsx: drop unused `fallback` parameter destructuring + the trailing `void (null as ...)` dead-statement (would trip no-unused-expressions). Kept `fallback?: ReactNode` on the Props interface as a documented compat shim so existing call sites still compile, with a comment explaining why it's no longer wired up. 3. openExternalUrl.test.ts: replace `typeof import('node:child_process').spawn` inline annotations (forbidden by @typescript-eslint/consistent-type-imports) with a `SpawnLike` type alias backed by a real `import type { spawn as SpawnFn }`. No behavior change. 718/718 tests pass, type-check clean, lint clean on all modified files. |

Hermes Agent ☤
The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.
Use any model you want — Nous Portal, OpenRouter (200+ models), NVIDIA NIM (Nemotron), Xiaomi MiMo, z.ai/GLM, Kimi/Moonshot, MiniMax, Hugging Face, OpenAI, or your own endpoint. Switch with hermes model — no code changes, no lock-in.
| A real terminal interface | Full TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output. |
| Lives where you do | Telegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity. |
| A closed learning loop | Agent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. Honcho dialectic user modeling. Compatible with the agentskills.io open standard. |
| Scheduled automations | Built-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended. |
| Delegates and parallelizes | Spawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns. |
| Runs anywhere, not just your laptop | Seven terminal backends — local, Docker, SSH, Singularity, Modal, Daytona, and Vercel Sandbox. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster. |
| Research-ready | Batch trajectory generation, Atropos RL environments, trajectory compression for training the next generation of tool-calling models. |
Quick Install
Linux, macOS, WSL2, Termux
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
Windows (native, PowerShell) — Early Beta
Heads up: Native Windows support is early beta. It installs and runs, but hasn't been road-tested as broadly as our Linux/macOS/WSL2 paths. Please file issues when you hit rough edges. For the most battle-tested Windows setup today, run the Linux/macOS one-liner above inside WSL2.
Run this in PowerShell:
irm https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.ps1 | iex
The installer handles everything: uv, Python 3.11, Node.js, ripgrep, ffmpeg, and a portable Git Bash (MinGit, unpacked to %LOCALAPPDATA%\hermes\git — no admin required, completely isolated from any system Git install). Hermes uses this bundled Git Bash to run shell commands.
If you already have Git installed, the installer detects it and uses that instead. Otherwise a ~45MB MinGit download is all you need — it won't touch or interfere with any system Git.
Android / Termux: The tested manual path is documented in the Termux guide. On Termux, Hermes installs a curated
.[termux]extra because the full.[all]extra currently pulls Android-incompatible voice dependencies.Windows: Native Windows is supported as an early beta — the PowerShell one-liner above installs everything, but expect rough edges and please file issues when you hit them. If you'd rather use WSL2 (our most battle-tested Windows path), the Linux command works there too. Native Windows install lives under
%LOCALAPPDATA%\hermes; WSL2 installs under~/.hermesas on Linux. The only Hermes feature that currently needs WSL2 specifically is the browser-based dashboard chat pane (it uses a POSIX PTY — classic CLI and gateway both run natively).
After installation:
source ~/.bashrc # reload shell (or: source ~/.zshrc)
hermes # start chatting!
Getting Started
hermes # Interactive CLI — start a conversation
hermes model # Choose your LLM provider and model
hermes tools # Configure which tools are enabled
hermes config set # Set individual config values
hermes gateway # Start the messaging gateway (Telegram, Discord, etc.)
hermes setup # Run the full setup wizard (configures everything at once)
hermes claw migrate # Migrate from OpenClaw (if coming from OpenClaw)
hermes update # Update to the latest version
hermes doctor # Diagnose any issues
CLI vs Messaging Quick Reference
Hermes has two entry points: start the terminal UI with hermes, or run the gateway and talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or Email. Once you're in a conversation, many slash commands are shared across both interfaces.
| Action | CLI | Messaging platforms |
|---|---|---|
| Start chatting | hermes |
Run hermes gateway setup + hermes gateway start, then send the bot a message |
| Start fresh conversation | /new or /reset |
/new or /reset |
| Change model | /model [provider:model] |
/model [provider:model] |
| Set a personality | /personality [name] |
/personality [name] |
| Retry or undo the last turn | /retry, /undo |
/retry, /undo |
| Compress context / check usage | /compress, /usage, /insights [--days N] |
/compress, /usage, /insights [days] |
| Browse skills | /skills or /<skill-name> |
/<skill-name> |
| Interrupt current work | Ctrl+C or send a new message |
/stop or send a new message |
| Platform-specific status | /platforms |
/status, /sethome |
For the full command lists, see the CLI guide and the Messaging Gateway guide.

Migrating from OpenClaw
If you're coming from OpenClaw, Hermes can automatically import your settings, memories, skills, and API keys.
During first-time setup: The setup wizard (hermes setup) automatically detects ~/.openclaw and offers to migrate before configuration begins.
Anytime after install:
hermes claw migrate # Interactive migration (full preset)
hermes claw migrate --dry-run # Preview what would be migrated
hermes claw migrate --preset user-data # Migrate without secrets
hermes claw migrate --overwrite # Overwrite existing conflicts
What gets imported:
- SOUL.md — persona file
- Memories — MEMORY.md and USER.md entries
- Skills — user-created skills →
~/.hermes/skills/openclaw-imports/ - Command allowlist — approval patterns
- Messaging settings — platform configs, allowed users, working directory
- API keys — allowlisted secrets (Telegram, OpenRouter, OpenAI, Anthropic, ElevenLabs)
- TTS assets — workspace audio files
- Workspace instructions — AGENTS.md (with
--workspace-target)
See hermes claw migrate --help for all options, or use the openclaw-migration skill for an interactive agent-guided migration with dry-run previews.
Contributing
We welcome contributions! See the Contributing Guide for development setup, code style, and PR process.
Quick start for contributors — clone and go with setup-hermes.sh:
git clone https://github.com/NousResearch/hermes-agent.git
