The analytics dashboard had three accuracy issues:
1. TOTAL TOKENS excluded cache_read and cache_write tokens — only counted
the non-cached input portion. With 90%+ cache hit rates typical in
Hermes, this dramatically undercounted actual token usage (e.g. showing
9.1M when the real total was 169M+).
2. The 'API Calls' card displayed session count (COUNT(*) from sessions
table), not actual LLM API requests. A single session makes 10-90 API
calls through the tool loop, so this was ~30x lower than reality.
3. cache_write_tokens was stored in the DB but never exposed through the
analytics API endpoint or frontend.
Changes:
- Add api_call_count column to sessions table (schema v7 migration)
- Persist api_call_count=1 per LLM API call in run_agent.py
- Analytics SQL queries now include cache_write_tokens and api_call_count
in daily, by_model, and totals aggregations
- Frontend TOTAL TOKENS card now shows input + cache_read + cache_write +
output (the full prompt total + output)
- API CALLS card now uses real api_call_count from DB
- New Cache Hit Rate card shows cache efficiency percentage
- Bar chart, tooltips, daily table, model table all use prompt totals
(input + cache_read + cache_write) instead of just input
- Labels changed from 'Input' to 'Prompt' to reflect the full prompt total
- TypeScript interfaces and i18n strings updated (en + zh)
- TestHealthDetailedEndpoint: 3 tests for the new API server endpoint
(returns runtime data, handles missing status, no auth required)
- TestProbeGatewayHealth: 5 tests for _probe_gateway_health()
(URL normalization, successful/failed probes, fallback chain)
- TestStatusRemoteGateway: 4 tests for /api/status remote fallback
(remote probe triggers, skipped when local PID found, null PID handling)
Addresses responsible disclosure from FuzzMind Security Lab (CVE pending).
The web dashboard API server had 36 endpoints, of which only 5 checked
the session token. The token itself was served from an unauthenticated
GET /api/auth/session-token endpoint, rendering the protection circular.
When bound to 0.0.0.0 (--host flag), all API keys, config, and cron
management were accessible to any machine on the network.
Changes:
- Add auth middleware requiring session token on ALL /api/ routes except
a small public whitelist (status, config/defaults, config/schema,
model/info)
- Remove GET /api/auth/session-token endpoint entirely; inject the token
into index.html via a <script> tag at serve time instead
- Replace all inline token comparisons (!=) with hmac.compare_digest()
to prevent timing side-channel attacks
- Block non-localhost binding by default; require --insecure flag to
override (with warning log)
- Update frontend fetchJSON() to send Authorization header on all
requests using the injected window.__HERMES_SESSION_TOKEN__

* feat: web UI dashboard for managing Hermes Agent (salvage of #8204/#7621)
Adds an embedded web UI dashboard accessible via `hermes web`:
- Status page: agent version, active sessions, gateway status, connected platforms
- Config editor: schema-driven form with tabbed categories, import/export, reset
- API Keys page: set, clear, and view redacted values with category grouping
- Sessions, Skills, Cron, Logs, and Analytics pages
Backend:
- hermes_cli/web_server.py: FastAPI server with REST endpoints
- hermes_cli/config.py: reload_env() utility for hot-reloading .env
- hermes_cli/main.py: `hermes web` subcommand (--port, --host, --no-open)
- cli.py / commands.py: /reload slash command for .env hot-reload
- pyproject.toml: [web] optional dependency extra (fastapi + uvicorn)
- Both update paths (git + zip) auto-build web frontend when npm available
Frontend:
- Vite + React + TypeScript + Tailwind v4 SPA in web/
- shadcn/ui-style components, Nous design language
- Auto-refresh status page, toast notifications, masked password inputs
Security:
- Path traversal guard (resolve().is_relative_to()) on SPA file serving
- CORS localhost-only via allow_origin_regex
- Generic error messages (no internal leak), SessionDB handles closed properly
Tests: 47 tests covering reload_env, redact_key, API endpoints, schema
generation, path traversal, category merging, internal key stripping,
and full config round-trip.
Original work by @austinpickett (PR #1813), salvaged by @kshitijk4poor
(PR #7621 → #8204), re-salvaged onto current main with stale-branch
regressions removed.
* fix(web): clean up status page cards, always rebuild on `hermes web`
- Remove config version migration alert banner from status page
- Remove config version card (internal noise, not surfaced in TUI)
- Reorder status cards: Agent → Gateway → Active Sessions (3-col grid)
- `hermes web` now always rebuilds from source before serving,
preventing stale web_dist when editing frontend files
* feat(web): full-text search across session messages
- Add GET /api/sessions/search endpoint backed by FTS5
- Auto-append prefix wildcards so partial words match (e.g. 'nimb' → 'nimby')
- Debounced search (300ms) with spinner in the search icon slot
- Search results show FTS5 snippets with highlighted match delimiters
- Expanding a search hit auto-scrolls to the first matching message
- Matching messages get a warning ring + 'match' badge
- Inline term highlighting within Markdown (text, bold, italic, headings, lists)
- Clear button (x) on search input for quick reset
