 ## 1. Overview and Purpose
 
-The Hermes Web UI is a lightweight, single-file web application that gives you
-a browser-based interface to the Hermes agent that is functionally equivalent to the CLI.
-It is modeled on the Claude interface: a three-panel layout with a sidebar for
-session management, a central chat area, and a right panel for workspace file browsing.
+The Hermes Web UI is a lightweight web application that gives you a browser-based
+interface to the Hermes agent that is functionally equivalent to the CLI. It is modeled on
+the Claude-style interface: a three-panel layout with a sidebar for session management,
+a central chat area, and a right panel for workspace file browsing.
 
 The design philosophy is deliberately minimal. There is no build step, no bundler, no
-frontend framework. Everything ships from a single Python file. This makes the code easy
-to modify from a terminal or by an agent, but it creates architectural debt that grows as
-the feature set expands.

+business logic modules (api/). The frontend is seven vanilla JS modules loaded from static/.

 Known gaps:
-- Tables: not supported, render as plain text
 - Nested lists: single regex pass, multi-level indentation not handled
 - Mixed bold+link in same line: may produce garbled output
-- Inline HTML: not sanitized (esc() only runs on code content)

-Implementation steps:
-1. Extract CSS and HTML to static/style.css and static/index.html. No content changes.
-   Server serves index.html from disk: handler reads Path('static/index.html').read_text()
-2. Extract JS to 6 static modules (complete -- app.js deleted Sprint 9)
-   Add GET /static/* handler in do_GET.
-3. Extract Session class and helpers to api/session_store.py
-4. Extract _run_agent_streaming and SSE helpers to api/streaming.py
-5. Extract parse_multipart and handle_upload to api/upload.py
-6. Extract list_dir and friends to api/files.py
-7. Refactor handlers.py to import from the above modules
-8. server.py becomes: config setup, start server, import Handler from handlers.py
-
-Benefit: Each file is under ~200 lines. Agents can read and modify individual files
-without loading the full 1100-line blob.
+Route extraction to api/routes.py completed in Sprint 11. server.py is now a ~76-line

+2. LOCK: all SESSIONS dict reads/writes wrapped with LOCK (from Sprint 1).
+3. Session index: `sessions/_index.json` maintained on every save/delete.
+   `all_sessions()` reads the index file (O(1)) instead of scanning all JSONs.

+2. All endpoints return clean 400/404 responses instead of tracebacks.
+3. Structured JSON request logging via `log_request()` override (Sprint 1).
 
-1. Add a validate() helper:
-   def validate(body, *required_fields):
-       missing = [f for f in required_fields if not body.get(f)]
-       if missing: raise ValueError(f"Missing required fields: {missing}")
+### Phase E: Frontend Modularization -- COMPLETE
 
-2. Refine the outer try/except in do_GET and do_POST:
-   except ValueError as e:
-       return j(self, {'error': str(e)}, status=400)
-   except KeyError as e:
-       return j(self, {'error': f'Not found: {e}'}, status=404)
-   except Exception as e:
-       log.exception('Unhandled error')
-       return j(self, {'error': 'Internal server error'}, status=500)
-   # Never expose tracebacks to the client (security risk even on localhost)
+Completed across Sprints 5, 6, and 9:
 
-3. Add request duration logging:

+1. HTML extracted to `static/index.html` (Sprint 6).
+2. CSS extracted to `static/style.css` (Sprint 4).
+3. `app.js` deleted Sprint 9, replaced by 6 focused modules:
+   `ui.js`, `workspace.js`, `sessions.js`, `messages.js`, `panels.js`, `boot.js`.
+   Loaded as standard `<script>` tags (not ES modules) in dependency order.

-### Phase E: Frontend Modularization (Priority: Medium, Effort: High)
-
-After Phase A splits the HTML/JS into files, Phase E improves the JavaScript itself.
-
-1. Switch to ES Modules (type="module"):
-   app.js deleted Sprint 9 -- replaced by 6 modules:
-   - state.js: export S, INFLIGHT
-   - sessions.js: session CRUD functions
-   - chat.js: send(), SSE handling
-   - files.js: loadDir(), openFile()
-   - upload.js: uploadPendingFiles(), addFiles(), renderTray()
-   - approval.js: approval card and polling
-   - markdown.js: renderMd()
-   - ui.js: setStatus, setBusy, showToast, syncTopbar
-   Each module imports what it needs from state.js and other modules.
-
-2. Replace renderMd with marked.js:
-   CDN: https://cdn.jsdelivr.net/npm/marked/marked.min.js
-   No bundler needed, ~50KB, handles tables, nested lists, HTML sanitization.
-   Usage: marked.parse(raw) -- drop-in replacement.
-   Add DOMPurify alongside for XSS sanitization of rendered HTML.
-
-3. Add Prism.js for syntax highlighting:
-   CDN: https://cdn.jsdelivr.net/npm/prismjs
-   Apply after renderMd: Prism.highlightAllUnder(element)
-   Supports 200+ languages with auto-detection.
+Remaining: renderMd() is still a hand-rolled regex chain. Tables partially supported.
+Replacing with marked.js + DOMPurify is a future improvement (not blocking).

+
+## Fixed
+
+### ~~Session title truncation / hover actions~~ -- Fixed (Sprint 16)
+
+- **Was:** Action icons reserved ~30px of space even when invisible, truncating titles.
+- **Fix:** Wrapped all action buttons in a `.session-actions` overlay container with `position:absolute`. Titles now use full available width. Actions appear on hover with a gradient fade from the right edge.
+
+### ~~Folder/project assignment interaction feels sticky~~ -- Fixed (Sprint 16)
+
+- **Was:** Folder icon stayed permanently visible (blue, 60% opacity) when a session belonged to a project.
+- **Fix:** Replaced `.has-project` persistent button with a colored left border matching the project color. The folder button now only appears in the hover overlay like all other actions.
+
+### ~~Project picker clipping and width~~ -- Fixed (v0.17.3)
+
+- **Was:** Picker was clipped by `overflow:hidden` on `.session-item` ancestors. With `position:fixed`, no containing block constrained width -- picker stretched to full viewport.
+- **Fix:** Dynamic width calculation (min 160px, max 220px). Event listener reordering. Cleanup sequence corrected. (PR #25)
+
+### ~~NameError crash in model discovery~~ -- Fixed (v0.17.3)
+
+- **Was:** `logger.debug()` called in custom endpoint `except` block, but `logger` was never imported in `config.py`. Every failed endpoint fetch crashed with `NameError`.
+- **Fix:** Replaced with silent `pass` -- unreachable endpoints are expected when no local LLM is configured. (PR #24)
+
+---
+
+## Notes
+
+- Sprint 16 replaced all emoji HTML entities with monochrome SVG line icons (`ICONS` constant in `sessions.js`).
+- All session action buttons now use the overlay pattern for consistent UX.

+# Why Hermes
+
+Hermes is a persistent, autonomous AI agent that lives on your server. It remembers everything,
+schedules work while you sleep, and gets more capable the longer it runs. This document explains
+the mental model, why that matters, and how Hermes compares to every major AI tool available today.
+
+---
+
+## The Core Idea: Assistants Forget. Agents Don't.
+
+Every time you open Claude Code, Codex, or a chat window, the tool starts from zero. It does not
+know who you are, what you worked on yesterday, how your repo is structured, or what bugs you
+already fixed. You re-explain yourself every single session. The tool is powerful in the moment
+and useless the next day.
+
+Hermes fills that gap. It runs on your server, retains context across every session, and acts
+on your behalf whether or not you are at a keyboard.
+
+```
+Assistant model:  You -> [Tool] -> Answer -> Done
+                  (tool forgets everything when the window closes)
+
+Agent model:      You <-> [Hermes] <-> (memory, skills, schedule, tools)
+                  (persistent, learns your stack, acts on your behalf, runs while you're offline)
+```
+
+---
+
+## The Three Pillars
+
+### 1. Memory That Compounds
+
+Hermes has layered memory that survives every session, every reboot, every model swap:
+
+- **User profile** -- who you are, your preferences, your communication style, things you've
+  corrected Hermes on
+- **Agent memory** -- facts about your environment, your toolchain, your project conventions
+- **Skills** -- reusable procedures Hermes discovers and saves; it never has to relearn how to
+  deploy your app, run your tests, or review a PR
+- **Session history** -- every past conversation is searchable; Hermes can recall what you
+  worked on last Tuesday
+
+When you correct Hermes, it remembers. When it solves a tricky problem, it saves the approach.
+When it learns your stack, that knowledge carries into every future session.
+
+### 2. Autonomous Scheduling
+
+Hermes can run jobs without you present -- every hour, every morning, on any cron schedule.
+It fires up a fresh session, runs the task, and delivers the result to wherever you want it:
+Telegram, Discord, Slack, Signal, WhatsApp, SMS, email, and more.
+
+Things Hermes can do while you sleep:
+
+- Review new pull requests on your GitHub repo and post a full verdict comment
+- Send you a morning briefing of news, markets, or anything else you care about
+- Run your test suite and alert you if something breaks
+- Watch a competitor's blog for new posts and summarize them
+- Monitor a datasource and notify you when a threshold is crossed
+
+### 3. Reach It From Anywhere
+
+Hermes runs on your server and is reachable from every surface: terminal over SSH, the web UI
+(this project), and messaging apps including Telegram, Discord, Slack, WhatsApp, Signal, and
+Matrix. Start a task from your phone, check it from the browser on your laptop, continue it in
+a terminal on a remote server. The same agent, memory, and history follow you everywhere.
+
+---
+
+## A Framework for AI Tools
+
+There are four distinct categories of AI tool. Understanding the category tells you what a tool
+can and cannot do.
+
+### Category 1: Chat Assistants
+*Claude.ai, ChatGPT, Gemini*
+
+You open a window, ask something, get an answer. No persistent memory beyond the conversation,
+no ability to run code or touch files, no way to act on your behalf. Excellent for Q&A,
+drafting, and brainstorming. You re-explain your context every session.
+
+### Category 2: IDE Integrations
+*GitHub Copilot, Cursor, Windsurf, Zed AI*
+
+Deep inside your editor. Autocomplete, inline diffs, refactors -- all excellent. Windsurf was
+earliest with workspace-scoped memory (Cascade Memories); Copilot has been shipping repo-level
+memory since late 2025 and is catching up. Cursor has no native memory as of early 2026. None
+have scheduling or messaging access. Tied to one machine and one editor.
+
+### Category 3: Agentic CLI Tools
+*Claude Code, Codex CLI, OpenCode, Aider*
+
+The current frontier for most developers. Can use real tools -- run shell commands, read and
+write files, search the web, call APIs. Great for deep, multi-step tasks in a single terminal
+session. All are adding memory and scheduling features to varying degrees (see comparisons below),
+but the core model is still session-scoped: you invoke it, it works, it stops.
+
+### Category 4: Persistent Autonomous Agents
+*Hermes, OpenClaw (as of early 2026)*
+
+All the tool use of Category 3, plus memory that accumulates across sessions, plus always-on
+scheduling, plus multi-modal access from any device or messaging app. Gets more useful over time
+rather than resetting to zero. Hermes and OpenClaw are the two primary open-source, self-hosted
+tools in this category. OpenClaw is a gateway-centric automation platform; Hermes is a
+self-improving agent that writes and reuses its own procedures from experience.
+
+---
+
+## How Hermes Compares
+
+### vs. OpenClaw
+
+OpenClaw is the most direct comparison to Hermes and the question most people ask first.
+Both are open-source, self-hosted, always-on agents with persistent memory, cron scheduling,
+and messaging app integration. If you're evaluating Hermes, you should evaluate OpenClaw too.
+
+OpenClaw (MIT, ~347k GitHub stars) is built around a **Gateway** control plane written in
+Node.js/TypeScript. It excels at broad personal automation: native Chrome/Chromium control for
+browser automation, the widest messaging platform support in the space (WhatsApp, Telegram,
+Signal, iMessage, LINE, WeChat, Slack, Discord, Teams, Matrix, and more), voice wake words,
+and a ClawHub skill marketplace where users share pre-built automations. The community is large
+and the ecosystem is growing fast.
+
+Hermes takes a different approach. It is built in Python and centers on a **self-improving
+agent loop** rather than a gateway control plane. The core difference is in how skills work:
+OpenClaw skills are primarily human-authored plugins installed from a marketplace; Hermes
+**writes and saves its own skills automatically** as part of every session. When Hermes solves
+a problem a new way, it saves the procedure and reuses it going forward without any user effort.
+
+Beyond the skills architecture, there are two other practical differences worth knowing:
+
+**Stability.** OpenClaw's community forums and GitHub issues document a recurring pattern of
+update-breaking regressions -- for example, Telegram integration was broken across multiple
+releases in early 2026. The unofficial WhatsApp Web protocol OpenClaw uses is known to
+disconnect and requires periodic re-pairing (this is documented in OpenClaw's own FAQ).
+Hermes has had no equivalent release breakages.
+
+**Security.** ClawHub's open publishing model has been exploited repeatedly. A community audit
+identified over a thousand malicious skills in the marketplace including prompt injections and
+tool-poisoning payloads; the community-maintained awesome-openclaw-skills list tracks confirmed
+removals and flags known bad actors. Hermes has no third-party marketplace and a correspondingly
+smaller attack surface.
+
+**OpenClaw's genuine strengths** are worth stating plainly: it has broader messaging coverage
+(iMessage, LINE, WeChat, Teams -- platforms Hermes does not support), native browser and
+computer control via Chrome CDP, voice wake words on macOS and iOS, a larger community, and
+more third-party integrations than Hermes. If those capabilities matter most to you, OpenClaw
+is worth a serious look.
+
+Where Hermes is the better fit: you want an agent that self-improves from experience without
+manual plugin authoring, you work in Python and want access to the ML/data science ecosystem,
+you want a stable deployment that does not break between updates, or you want a full web chat
+UI rather than a monitoring dashboard.

+
+### vs. Claude Code (Anthropic)
+
+Claude Code is Anthropic's official agentic CLI and one of the best tools in Category 3.
+In a single focused session it is capable -- deep code understanding, shell access, file
+editing, multi-step reasoning.
+
+Claude Code has been adding features rapidly and the gap is narrowing:
+
+- **Hooks system** -- 13 event types (SessionStart, PreToolUse, PostToolUse, Stop, etc.) with
+  4 handler types (shell command, HTTP endpoint, LLM prompt, sub-agent); deterministic
+  non-LLM control over the agent lifecycle
+- **Plugins / Skills** -- installable via `/plugin install`, hot-reloaded from `~/.claude/skills`,
+  with a marketplace; skills and slash commands unified as of v2.1.0
+- **Scheduling** -- `/loop` (session-scoped), cloud-managed cron via `claude.ai/code/scheduled`
+  (Anthropic infrastructure, minimum interval applies), and desktop app automations
+- **Messaging channels** -- Telegram, Discord, iMessage, and webhooks via the Channels feature
+  (research preview, v2.1.80+); deep Slack integration that triggers cloud sessions and creates PRs
+- **Claude Cowork** -- a separate product for knowledge workers; connects to 38+
+  services via MCP including Slack, Gmail, Microsoft Teams, Notion, Jira, Salesforce, and more
+- **Memory** -- CLAUDE.md and MEMORY.md for project-level context; auto-memory rolling out
+
+These are real features. The key differences that remain:
+
+- Claude Code's scheduling runs on **Anthropic's cloud** (or requires the desktop app open),
+  not a self-hosted server; cloud jobs have a minimum interval and your data leaves your hardware
+- Memory is **project-file-based** (CLAUDE.md / MEMORY.md), not a knowledge graph that
+  accumulates automatically across all your work; auto-memory is still rolling out
+- **Not provider-agnostic** -- routes through Bedrock or Vertex but always hits a Claude model;
+  you cannot switch to GPT, Gemini, or a local model
+- **Not open source** -- proprietary; the CLI ships obfuscated JavaScript
+- Messaging channels are a **research preview** requiring Bun runtime; not yet production-grade
+
+Hermes can use Claude Code as a sub-agent. For large implementation tasks, Hermes can spawn
+Claude Code to handle the heavy lifting and fold the result back into its own memory and history.
+
+| | Claude Code | Hermes |
+|---|---|---|
+| Persistent memory (automatic) | Partial (CLAUDE.md / MEMORY.md, rolling out) | Yes |
+| Skills / hooks system | Yes (Hooks + Plugin/Skills marketplace) | Yes (auto-generated from experience) |
+| Scheduled jobs (self-hosted) | No (cloud or desktop-app only) | Yes |
+| Messaging access | Partial (Telegram/Discord/iMessage via research preview; Slack native) | Yes (10+ platforms, production) |
+| Cowork connectors (Slack, Gmail, etc.) | Yes (via Claude Cowork, separate product) | Via agent tool use |
+| Web UI | Yes (claude.ai/code, Anthropic-hosted) | Yes (self-hosted) |
+| Provider-agnostic | No (Claude models only, via Bedrock/Vertex) | Yes (any provider) |
+| Self-hosted scheduling | No | Yes |
+| Open source | No | Yes |
+| Runs as sub-agent of Hermes | Yes | N/A |
+
+### vs. Codex CLI (OpenAI)
+
+Codex CLI is OpenAI's open-source agentic terminal tool (Apache 2.0, ~73k GitHub stars). It
+supports 10+ providers including Anthropic, Google, Mistral, Groq, and local models via Ollama.
+It added persistent session memory in v0.100.0 with `codex resume`. The desktop app has an
+Automations feature for scheduled local tasks.
+
+The CLI itself has no native scheduling (open feature request as of early 2026). Memory is
+session-history-based rather than a living knowledge graph. No messaging app access. A strong
+tool for single-session coding; Hermes adds the always-on layer on top.
+
+| | Codex CLI | Hermes |
+|---|---|---|
+| Persistent memory | Partial (session history + AGENTS.md) | Yes (automatic, layered) |
+| Scheduled jobs | Partial (desktop app only; CLI has none) | Yes |
+| Messaging app access | No | Yes |
+| Web UI | No | Yes (self-hosted) |
+| Provider-agnostic | Yes (10+ providers) | Yes (10+ providers) |
+| Self-hosted | Yes | Yes |
+| Open source | Yes (Apache 2.0) | Yes |
+
+### vs. OpenCode
+
+OpenCode is an open-source TUI agentic coding assistant, provider-agnostic across 75+ providers.
+It has a WebUI embedded in its binary and an official desktop app. It uses SQLite for session
+history and AGENTS.md for project context.
+
+No native scheduled jobs (a community background plugin exists), no first-party messaging
+integration (community Telegram bots exist but require manual setup), and no automatic
+cross-session semantic memory. Good for interactive terminal coding sessions.
+
+| | OpenCode | Hermes |
+|---|---|---|
+| Persistent memory | Partial (session history + AGENTS.md) | Yes (automatic, layered) |
+| Scheduled jobs | No (community plugin only) | Yes |
+| Messaging app access | No (community Telegram bot only) | Yes (first-party, 10+ platforms) |
+| Web UI | Yes (embedded + desktop app) | Yes (self-hosted) |
+| Mobile access | No | Yes |
+| Skills system | No | Yes |
+| Provider-agnostic | Yes (75+ providers) | Yes |
+| Open source | Yes | Yes |
+
+### vs. Cursor / Windsurf / Copilot
+
+Category 2 tools -- exceptional at in-editor autocomplete, inline diffs, and code review.
+Not competing for the same job as Hermes, and they work well alongside it.
+
+Windsurf was earliest with workspace-scoped memory (Cascade Memories); Copilot has been
+shipping repo-level memory since late 2025. Cursor has no native cross-session memory as of
+early 2026. None have scheduling or messaging access.
+
+| | Cursor | Windsurf | Copilot | Hermes |
+|---|---|---|---|---|
+| In-editor autocomplete | Excellent | Excellent | Excellent | No |
+| Inline diff / refactor | Yes | Yes | Yes | Via shell |
+| Cross-session memory | No | Yes (workspace) | Partial (repo, early access) | Yes |
+| Scheduled background jobs | No | No | No | Yes |
+| Messaging app / mobile | No | No | No | Yes |
+| Terminal tool use | Limited | Limited | Limited | Full |
+| Self-hosted | No | No | No | Yes |
+| Provider-agnostic | Partial | Partial | No | Yes |
+| Open source | No | No | No | Yes |
+
+### vs. Claude.ai / ChatGPT
+
+Category 1. For drafting, Q&A, and brainstorming in the moment, both are excellent.
+
+Claude.ai memory has been improving -- it now generates memory from chat history, not just
+user-curated entries. Claude.ai can also execute code and read/write files in a sandboxed
+environment via Artifacts. These are real capabilities, just not the same as direct filesystem
+or shell access on your own server.

+|---|---|---|
+| Memory across conversations | Yes (improving; auto-generated from history) | Yes (deep, automatic) |
+| Runs shell commands | No | Yes |
+| Code execution | Sandboxed (Artifacts) | Yes (full shell) |
+| Reads / writes files | Sandboxed (Artifacts) | Yes (full filesystem) |

+| Messaging apps | No | Yes |

+| Provider-agnostic | No | Yes |

+

+
+## The Compounding Advantage
+
+What matters most about Hermes is that it improves over time. That is the point.
+
+Every time Hermes encounters a new environment, it saves facts to memory. Every time it solves
+a problem a new way, it saves the approach as a skill. Every time you correct it, it updates its
+profile of you. Every session, every scheduled job, every tool call, the agent gets more
+calibrated to you and your workflow.
+
+A Claude Code session on day one and day one hundred are identical. A Hermes agent on day one
+and day one hundred is smarter about you -- it knows your stack, your conventions, your
+preferences, and the solutions that have worked before.
+
+---
+
+## Who Hermes Is For
+
+**Solo developers and power users** who don't want to re-explain their stack every session and
+want an AI that actually knows their environment.
+
+**Teams on a shared server** where multiple people want Claude-quality AI access without each
+paying for a separate subscription or running local tooling.
+
+**Automation-heavy workflows** where you want an AI running tasks on a schedule, delivering
+results to your phone, without babysitting it.
+
+**Privacy-conscious users** who want their conversations, memory, and files on their own
+hardware.
+
+**Multi-model users** who want to switch between OpenAI, Anthropic, Google, DeepSeek, and
+others based on cost, capability, or rate limits, without rebuilding their workflow each time.
+
+---
+
+## Scope and Limits
+
+**Hermes lives in the terminal, browser, and messaging apps.** For in-editor autocomplete and
+inline diffs, use Cursor or Windsurf alongside it -- they do that job better.
+
+**You run Hermes on your own server.** That means initial setup, but your data stays on your
+hardware and you control the schedule, the models, and the costs.
+
+**Hermes is an orchestration and memory layer.** It makes whatever model you point it at more
+useful over time. The models do the reasoning; Hermes makes sure that reasoning accumulates into
+something durable.

 # Hermes Web UI
 
-A lightweight, dark-themed browser interface for Hermes.
-Full parity with the CLI experience -- everything you can do from a terminal,
+[Hermes Agent](https://hermes-agent.nousresearch.com/) is a sophisticated autonomous agent that lives on your server, accessed via a terminal or messaging apps, remembers what it learns, and gets more capable the longer it runs.
+
+Hermes WebUI is a lightweight, dark-themed web app interface in your browser for [Hermes Agent](https://hermes-agent.nousresearch.com/).
+Full parity with the CLI experience - everything you can do from a terminal,
 you can do from this UI. No build step, no framework, no bundler. Just Python
 and vanilla JS.
 
 Layout: three-panel Claude-style. Left sidebar for sessions and tools,
 center for chat, right for workspace file browsing.

+
+This gives you nearly **1:1 parity with Hermes CLI from a convenient web UI** which you can access securely through an SSH tunnel from your Hermes setup. Single command to start this up, and a single command to SSH tunnel for access on your computer. Every single part of the web UI uses your existing Hermes agent and existing models, without requiring any additional setup.
+
+---
+
+## Why Hermes
+
+Most AI tools reset every session. They don't know who you are, what you worked on, or what
+conventions your project follows. You re-explain yourself every time.
+
+Hermes retains context across sessions, runs scheduled jobs while you're offline, and gets
+smarter about your environment the longer it runs. It uses your existing Hermes agent setup,
+your existing models, and requires no additional configuration to start.
+
+What makes it different from other agentic tools:
+
+- **Persistent memory** — user profile, agent notes, and a skills system that saves reusable
+  procedures; Hermes learns your environment and does not have to relearn it
+- **Self-hosted scheduling** — cron jobs that fire while you're offline and deliver results to
+  Telegram, Discord, Slack, Signal, email, and more
+- **10+ messaging platforms** — the same agent available in the terminal is reachable from your phone
+- **Self-improving skills** — Hermes writes and saves its own skills automatically from experience;
+  no marketplace to browse, no plugins to install
+- **Provider-agnostic** — OpenAI, Anthropic, Google, DeepSeek, OpenRouter, and more
+- **Orchestrates other agents** — can spawn Claude Code or Codex for heavy coding tasks and bring
+  the results back into its own memory
+- **Self-hosted** — your conversations, your memory, your hardware
+
+**vs. the field** *(landscape is actively shifting — see [HERMES.md](HERMES.md) for the full breakdown)*:
+
+| | OpenClaw | Claude Code | Codex CLI | OpenCode | Hermes |
+|---|---|---|---|---|---|
+| Persistent memory (auto) | Yes | Partial† | Partial | Partial | Yes |
+| Scheduled jobs (self-hosted) | Yes | No‡ | No | No | Yes |
+| Messaging app access | Yes (15+ platforms) | Partial (Telegram/Discord preview) | No | No | Yes (10+) |
+| Web UI (self-hosted) | Dashboard only | No | No | Yes | Yes |
+| Self-improving skills | Partial | No | No | No | Yes |
+| Python / ML ecosystem | No (Node.js) | No | No | No | Yes |
+| Provider-agnostic | Yes | No (Claude only) | Yes | Yes | Yes |
+| Open source | Yes (MIT) | No | Yes | Yes | Yes |
+
+† Claude Code has CLAUDE.md / MEMORY.md project context and rolling auto-memory, but not full automatic cross-session recall  
+‡ Claude Code has cloud-managed scheduling (Anthropic infrastructure) and session-scoped `/loop`; no self-hosted cron
+
+**The closest competitor is OpenClaw** — both are always-on, self-hosted, open-source agents
+with memory, cron, and messaging. The key differences: Hermes writes and saves its own skills
+automatically as a core behavior (OpenClaw's skill system centers on a community marketplace);
+Hermes is more stable across updates (OpenClaw has documented release regressions and ClawHub
+has had security incidents involving malicious skills); and Hermes runs natively in the Python
+ecosystem. See [HERMES.md](HERMES.md) for the full side-by-side.

+## Accessing on your phone with Tailscale
+
+[Tailscale](https://tailscale.com) is a zero-config mesh VPN built on
+WireGuard. Install it on your server and your phone, and they join the same
+private network -- no port forwarding, no SSH tunnels, no public exposure.
+
+The Hermes Web UI is fully responsive with a mobile-optimized layout
+(hamburger sidebar, bottom navigation bar, touch-friendly controls), so it
+works well as a daily-driver agent interface from your phone.
+
+**Setup:**
+
+1. Install [Tailscale](https://tailscale.com/download) on your server and
+   your iPhone/Android.
+2. Start the WebUI listening on all interfaces with password auth enabled:
+
+```bash
+HERMES_WEBUI_HOST=0.0.0.0 HERMES_WEBUI_PASSWORD=your-secret ./start.sh
+```
+
+3. Open `http://<server-tailscale-ip>:8787` in your phone's browser
+   (find your server's Tailscale IP in the Tailscale app or with
+   `tailscale ip -4` on the server).
+
+That's it. Traffic is encrypted end-to-end by WireGuard, and password auth
+protects the UI at the application level. You can add it to your home screen
+for an app-like experience.
+
+> **Tip:** If using Docker, set `HERMES_WEBUI_HOST=0.0.0.0` in your
+> `docker-compose.yml` environment (already the default) and set
+> `HERMES_WEBUI_PASSWORD`.

+## Sections Added Post-Sprint 10 (Sprints 11-19)
+
+The following features were added in Sprints 11-19 and need manual browser testing.
+Each has automated API-level tests in `tests/test_sprint{N}.py`.
+
+### Sprint 11: Multi-Provider Models
+- Open model dropdown. Verify models grouped by provider (OpenAI, Anthropic, Google, etc.)
+- If custom `base_url` configured in config.yaml, verify local models appear in dropdown.
+- Switch model. Send a message. Verify response uses selected model.
+
+### Sprint 12: Settings + Pin + Import
+- Click gear icon. Settings overlay opens.
+- Change default model, save. Restart server. Verify setting persisted.
+- Pin a session (star icon in hover overlay). Verify it floats to top of list.
+- Export session as JSON. Import it back. Verify messages restored.
+
+### Sprint 13: Alerts + Session QoL
+- Duplicate a session (copy icon in hover overlay). Verify "(copy)" title.
+- Browser tab title updates to active session name. Switch sessions — title changes.
+
+### Sprint 14: Visual Polish + Workspace Ops
+- Create a mermaid code block in a response. Verify diagram renders inline.
+- Message timestamps visible next to role labels (hover for full date).
+- Double-click a file in workspace panel to rename. Enter saves, Escape cancels.
+- Create a folder via folder icon in workspace header.
+- Add `#tag` to session title. Verify tag chip appears in sidebar. Click to filter.
+- Archive a session. Verify it disappears. Toggle "Show archived" to see it.
+
+### Sprint 15: Session Projects
+- Click "+" in project bar to create a project. Type name, Enter.
+- Click a project chip to filter sessions.
+- Hover a session → click folder icon → assign to project via picker.
+- Verify colored left border appears on assigned session.
+- Double-click project chip to rename. Right-click to delete.
+- Code blocks have a "Copy" button. Click → "Copied!" feedback.
+- Messages with 2+ tool cards show "Expand all / Collapse all" toggle.
+
+### Sprint 16: Sidebar Visual Polish
+- Session titles use full sidebar width (no truncated space for hidden icons).
+- Hover a session → action buttons appear from right with gradient fade.
+- All icons are monochrome SVGs (not emoji). Consistent across platforms.
+- Pinned sessions show small gold star inline. Unpinned = no star, full title width.
+- Active session has gold highlight (not blue). Overlay gradient matches.
+- Double-click to rename → overlay hides during rename.
+
+### Sprint 17: Workspace + Slash Commands + Send Key
+- Navigate into a subdirectory. Breadcrumb bar appears with clickable segments.
+- Up button in panel header navigates to parent. Hidden at root.
+- Type `/` in composer → autocomplete dropdown appears. Arrow keys navigate.
+- Type `/help` → lists all commands. `/clear` clears conversation. `/model` switches.
+- Settings panel: change send key to Ctrl+Enter. Verify Enter inserts newline.
+
+### Sprint 18: Thinking + Tree View + Preview Fix
+- View a file in workspace. Click a breadcrumb or folder → preview closes automatically.
+- Click a directory toggle arrow (▸) → expands in-place showing children.
+- Click again (▾) → collapses. Double-click navigates into it (breadcrumb view).
+- If model returns thinking blocks (Claude extended thinking), verify collapsible gold card appears above response.
+
+### Sprint 19: Auth + Security
+- No password set: everything works as normal. No login page.
+- Set `HERMES_WEBUI_PASSWORD=test` env var. Restart. All pages redirect to `/login`.
+- Login page: minimal card, password field, "Sign in" button.
+- Enter correct password → redirected to `/`. Cookie set (24h).
+- Enter wrong password → error message, stay on login page.
+- Settings panel: set password via "Access Password" field. Auth activates.
+- "Sign Out" button visible when auth active. Click → redirected to /login.
+- API calls without auth cookie → 401 JSON response.
+- Check response headers: `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`.
+
+### Sprint 20: Voice Input + Send Button
+- Mic button visible in composer (Chrome/Edge). Hidden in Firefox.
+- Tap mic → button turns red with pulse, "Listening..." indicator appears.
+- Speak → live transcription appears in textarea.
+- Stop speaking → auto-stops after ~2s silence. Text stays editable.
+- Tap mic again or Send → stops recording, sends text.
+- Type text, then tap mic → spoken text appends to existing text (doesn't replace).
+- Send button hidden when textarea is empty. Appears with pop-in animation when typing.
+- Send button is icon-only circle (no "Send" text label). Blue with glow.
+- Attach a file with no text → send button appears.
+- Send message → button disappears after textarea clears.
+- While agent is responding → send button hidden.
+
+### Sprint 21: Mobile Responsive + Docker
+- Open on mobile viewport (<640px): hamburger icon visible in topbar.
+- Tap hamburger → sidebar slides in from left with backdrop overlay.
+- Tap outside sidebar → closes. Tap a session → closes and loads session.
+- Bottom navigation bar: 5 tabs (Chat, Tasks, Skills, Memory, Spaces).
+- Tap "Tasks" in bottom nav → sidebar opens showing Tasks panel.
+- Tap "Chat" in bottom nav → sidebar closes (chat is in main area).
+- Files button in topbar → right panel slides in from right.
+- All touch targets are at least 44px (session items, buttons, icons).
+- Desktop viewport (>640px): no hamburger, no bottom nav, no mobile elements.
+- Docker: `docker compose up -d` starts server on port 8787.
+- Docker: session data persists across container restarts (named volume).
+
+### Sprint 22: Multi-Profile Support
+- Profile chip in topbar (purple accent). Click → dropdown with all profiles.
+- Dropdown shows gateway status dots, model info, skill count per profile.
+- Click a profile → switches; model dropdown, skills, memory, cron refresh.
+- "Manage profiles" link opens Profiles sidebar panel.
+- Profiles panel: cards with name, model, provider, skill count, API key status.
+- "Use" button switches profile. Delete button removes non-default profiles.
+- "+ New profile" form: name validation (lowercase + hyphens), clone config checkbox.
+- Create profile → appears in list and dropdown.
+- Delete profile → confirm dialog. Auto-switches to default if deleting active.
+- Attempt switch while agent busy → blocked with toast message.
+- With hermes-agent not installed → only default profile shown, graceful fallback.

+# Hermes Web UI — Themes
+
+Hermes Web UI supports pluggable color themes. Six themes ship built-in, and
+you can create your own with pure CSS — no Python changes needed.
+
+---
+
+## Switching Themes
+
+**Settings panel:** Click the gear icon, select a theme from the dropdown. The
+preview is instant — the UI updates as you click through options.
+
+**Slash command:** Type `/theme dark` or `/theme light` in the composer.
+
+**Themes persist** across page reloads and server restarts (stored in
+`settings.json` server-side, with `localStorage` for flicker-free loading).
+
+---
+
+## Built-in Themes
+
+| Theme | Description |
+|-------|-------------|
+| **Dark** (default) | Deep navy/indigo with muted blue accents. Easy on the eyes for long sessions. |
+| **Light** | Warm off-white with dark text. High contrast for bright environments. |
+| **Slate** | Warm charcoal, lighter than Dark. Easier on the eyes for extended use. |
+| **Solarized Dark** | Ethan Schoonover's classic dark palette. Teal background, warm accents. |
+| **Monokai** | Warm dark theme inspired by the Monokai editor scheme. Green/pink accents. |
+| **Nord** | Arctic blue-gray palette from the Nord color system. Calm and minimal. |
+| **Custom themes** | Any string accepted by `settings.json`, `POST /api/settings`, and `/theme` if added to the picker/command list. Pure CSS variables only. |
+
+---
+
+## Creating a Custom Theme
+
+A theme is a CSS block that overrides the color variables. Add it to
+`static/style.css` (or a separate file that you link after the main stylesheet).
+
+### Step 1: Define your theme block
+
+Every color in the UI comes from these CSS variables:
+
+```css
+:root[data-theme="your-theme-name"] {
+  /* Core palette */
+  --bg: #1a1a2e;          /* Main background */
+  --sidebar: #16213e;      /* Sidebar background */
+  --border: rgba(255,255,255,0.08);   /* Subtle borders */
+  --border2: rgba(255,255,255,0.14);  /* Stronger borders */
+  --text: #e8e8f0;         /* Primary text color */
+  --muted: #8888aa;        /* Secondary/muted text */
+  --accent: #e94560;       /* Accent color (errors, warnings, delete) */
+  --blue: #7cb9ff;         /* Primary action color (links, active states) */
+  --gold: #c9a84c;         /* Secondary accent (pinned items, gold highlights) */
+  --code-bg: #0d1117;      /* Code block background */
+
+  /* Surface and chrome (required for full theme polish) */
+  --surface: #1a2535;      /* Dropdowns, popups, toast, approval card */
+  --topbar-bg: rgba(22,33,62,.98);   /* Topbar background */
+  --main-bg: rgba(26,26,46,0.5);    /* Main chat area background */
+  --input-bg: rgba(255,255,255,.04); /* Input/button subtle backgrounds */
+  --hover-bg: rgba(255,255,255,.06); /* Hover state backgrounds */
+  --focus-ring: rgba(124,185,255,.35); /* Focus border color */
+  --focus-glow: rgba(124,185,255,.08); /* Focus box-shadow glow */
+
+  /* Typography (required for readable text across themes) */
+  --strong: #fff;          /* Bold text in messages */
+  --em: #c9c9e8;           /* Italic text in messages */
+  --code-text: #f0c27f;    /* Inline code text color */
+  --code-inline-bg: rgba(0,0,0,.35); /* Inline code background */
+  --pre-text: #e2e8f0;     /* Code block text color */
+}
+```
+
+The **core palette** controls the overall mood. The **surface/chrome** and
+**typography** variables are part of the standard theme contract — define all
+of them for a complete theme.
+
+For **light themes**, you also need `:root[data-theme="name"]` overrides
+for elements that use `rgba(255,255,255,.XX)` hover/border effects (these
+are invisible on light backgrounds). See the built-in light theme for the
+full pattern — it overrides ~45 selectors for proper dark-on-light contrast
+on hover states, borders, chips, role labels, session items, and
+interactive elements.
+
+### Step 2: Add it to the theme picker (optional)
+
+To make your theme appear in the Settings dropdown, add an `<option>` to the
+theme `<select>` in `static/index.html`:
+
+```html
+<option value="your-theme-name">Your Theme Name</option>
+```
+
+And update the `/theme` command's valid theme list in `static/commands.js`.
+
+### Step 3: Test it
+
+Switch to your theme via `/theme your-theme-name` or the Settings panel.
+Check these areas:
+- Sidebar session list (hover states, active state, project borders)
+- Message bubbles (user vs assistant styling)
+- Code blocks (background contrast, copy button visibility)
+- Tool cards (running indicator, expand/collapse)
+- Settings panel and login page
+- Mobile layout (hamburger sidebar, bottom nav)
+
+### Tips
+
+- **Light themes** need scrollbar and selection overrides, plus the full
+  text/code set (`--strong`, `--em`, `--code-text`, `--code-inline-bg`,
+  `--pre-text`) or they will look broken.
+- The **logo gradient** uses `--accent` automatically, so it adapts to your
+  theme without extra work.
+- **Prism.js syntax highlighting** uses its own CDN stylesheet (Tomorrow theme).
+  It works well on dark themes; on light themes the contrast is acceptable but
+  not perfect. Custom Prism theme support is planned for a future update.
+- **No server changes needed.** The `theme` setting in `settings.json` accepts
+  any string — your custom theme name will persist without code changes.
+
+---
+
+## How Themes Work Internally
+
+1. Each theme is a `:root[data-theme="name"]` CSS block that overrides variables.
+2. Switching themes sets `document.documentElement.dataset.theme = name` in JS.
+3. A tiny inline `<script>` in `<head>` reads `localStorage` before the
+   stylesheet loads — this prevents a flash of the wrong theme on page load.
+4. The theme preference is saved server-side via `POST /api/settings` and
+   loaded on boot via `GET /api/settings`.
+5. The `/theme` command and Settings dropdown both update the DOM, localStorage,
+   and server settings simultaneously.
+
+---
+
+## Contributing a Theme
+
+To contribute a new built-in theme:
+
+1. Add your `:root[data-theme="name"]` block to `static/style.css`
+2. Add the `<option>` to the Settings panel in `static/index.html`
+3. Add the theme name to the valid list in `cmdTheme()` in `static/commands.js`
+4. Test on desktop and mobile
+5. Open a PR — themes are pure CSS additions with no backend changes needed
