Two pieces of upstream promotion came out of this deployment. The sidebar "apiRelay" tab only opened a registration page on a third-party site, so it goes with no replacement. The circuit badge next to Settings was not what it looked like. It opened an ESP32 device manager: add a device, show LAN status, remote connect/disconnect, rename, delete, backed by six REST routes and an mcu_devices table. The purchase button inside that dialog was the promotional part; the rest was real device management. Since the hardware is out of scope here, the entire feature is removed rather than just the link that pointed upstream - UI entry, client API, routes, controller, store, schema, locale strings, and the one GlobalAgentServer method that only existed to answer its status column. Table creation is dropped but no DROP TABLE was added, so an already-provisioned database keeps its rows as harmless orphans instead of losing data on upgrade. DevicesView and the hermes.devices route are untouched: that is LAN device discovery, a separate feature. AGENTS.md now records the removal so the badge does not come back.

Agent Map
This file is a short map for coding agents. Keep detailed guidance in docs/
and keep this file small enough to fit into every task context.
First Reads
DEVELOPMENT.md- project commands, coding rules, test rules, and PR shape.ARCHITECTURE.md- package boundaries, data ownership, and runtime flow.docs/harness/README.md- how this repository is prepared for agent work.docs/harness/validation.md- which checks to run for each change type.docs/harness/worktree-runbook.md- isolated local dev and test setup.docs/harness/pr-review.md- self-review checklist before pushing.
Common Commands
npm ci --ignore-scripts
npm run harness:check
npm run test
npm run test:e2e
npm run build
Use the smallest relevant check while iterating. Before a broad PR, run
npm run harness:check, npm run test:coverage, npm run test:e2e, and
npm run build.
Code Ownership Map

Hard Rules
- Keep routes thin: put request handling in controllers and reusable behavior in services.
- Keep Web UI state under
HERMES_WEB_UI_HOMEorHERMES_WEBUI_STATE_DIR. - Keep Hermes Agent state separate from Web UI state.
- Register local API routes before proxy catch-all routes.
- Use structured APIs and argument arrays instead of shell string construction.
- Add user-facing strings to every locale file.
- Do not mix unrelated refactors into a bug fix.
Red Lines
packages/server/src/services/hermes/agent-bridge/python/is read-only vendored code.- The
/chat-runSocket.IO event contract must not change event names, field names, field types, or emission timing. Adding optional fields is allowed. - Hermes
state.dbis read-only. Node-side code must never open it; read session history through the bridge'sgetHistory/getOutputinstead. services/hermes/group-chat/,lib/context-compressor/, andservices/hermes/context-engine/are the chat chain: changes require adocs/chat-chain-changes/<date>-<slug>.mdfragment.packages/desktopandpackages/websiteare removed; do not reintroduce them.- This repo is a reimplementation. A few upstream service addresses are load-bearing
and are deliberately kept, each with a whitelist entry in
scripts/harness-check.mjs: the global-agent relay (api.hermes-studio.ai), the OpenRouter referer, and the sidebar website link. Do not "clean them up" as legacy brand text — removing them breaks those features. Do not read the relay address as project identity: this deployment is not affiliated with the upstream operator. - The upstream ESP32 / MCU device feature was removed on purpose (no UI entry, no REST routes, no store, no locale strings). Do not reintroduce it. Its "purchase" affordance was the only part that merely advertised the upstream site; the rest was real device management, and the whole thing is gone because the hardware is out of scope here.
- The online-update channel (
runtime-version-manager.ts) has no default URL. It readsHERMES_WEB_UI_VERSION_MANIFEST_URL/HERMES_WEB_UI_DOWNLOAD_BASE_URL/HERMES_WEB_UI_GITHUB_REPOand degrades with a named error when unset. Do not reintroduce a hardcoded upstream URL. - ArkScope vendor (
packages/client/src/vendor/arkscore/) is decorative only: login-page title, Journey graph background, first-load / empty states. Never in chat, forms, tables, or click-dense areas. Decorative layers must bepointer-events: noneand carry no information or interaction.
When The Agent Gets Stuck
Improve the harness instead of repeating the same prompt. Add missing docs, tests, logs, scripts, or CI checks so the next agent can see and verify the constraint directly.
