Closes the auto-send hole that let earlier models invent signatures
(e.g. signing 'David' for a user named Felix) and SMTP them to real
recipients before the user could review.
New setting: agent_email_confirm (default True).
When on, the MCP send_email and reply_to_email tools no longer SMTP
directly — they write the composed email to scheduled_emails with a new
status 'agent_draft' (far-future send_at so the scheduled-send poller
ignores them) and return a {pending: true, pending_id, to, subject,
body, message: ...} payload. The model surfaces that to the user.
Backend endpoints to approve / cancel:
- GET /api/email/pending → list staged drafts for the owner
- POST /api/email/pending/{id}/approve → flip status to 'pending' +
backdate send_at so the
existing scheduled-send
poller delivers immediately
- DELETE /api/email/pending/{id} → status = 'cancelled'
UI:
- Settings / AI Defaults gets a new 'Email Safety' card with the
toggle, default on.
- Tool descriptions for send_email and reply_to_email now include the
pending behavior + an explicit 'DO NOT invent a signature, do not
type a person's name' guardrail.
Pass 2 (next): inline chat card with Send / Discard buttons so the user
doesn't have to type a confirmation reply. Today's prompt + the listing
endpoint give the model a clean path to surface drafts.
The bell is already gated on settings.reminder_channel === 'email', but
the check only ran at email-library init — so switching the reminder
channel in Settings didn't update the bell until you reopened Email.
- Settings/Reminders channel-change handler now dispatches
odysseus-reminder-channel-changed { channel } after saving.
- emailLibrary listens for it and re-runs _syncEmailReminderBellVisibility
with the new channel value.
Two months of iteration on the Settings panel, integration forms, and
small visual nudges across the app. Highlights:
Settings restructure
- Add Models: split into separate Local + API cards (no more in-card
tabs); each fuses Type/Provider with the URL input.
- Added Models: new dedicated sidebar tab, with Probe + Clear-offline
pulled into its header; Local/API sub-section icons accent-tinted.
- Search: Web Search and a new Deep Research card (Model + tuning),
with a cross-link to AI Defaults. Provider hints use real clickable
anchors; Web Search Test button shows a whirlpool spinner.
- AI Defaults: Image Generation card returns; Research Model card
carries only Endpoint+Model with a cross-link to Search; Vision /
Default / Utility fallbacks unified under one numbered-row design
matching Search's chain.
- API Permissions (was 'API Tokens'): per-row rename, inline
Permissions toggle that expands the scope-edit panel, in-field
copy icons (icon→check on success). Empty state accent-tinted.
- Integrations: + Add Integration drops a type-picker menu directly
under the button (drop-up on tight viewports); each integration
form (API, CalDAV, CardDAV, Email, Codex/Claude, Vault, MCP) uses
the same accent-outlined Save/Test/Cancel buttons right-aligned.
- Danger Zone: Wipe→Delete with trash icons; new 'Delete everything'
row at the bottom that loops every category.
AI Synthesis (Reminders)
- Persona dropdown sourced from PROMPT_TEMPLATES + custom preset.
- src/reminder_personas.py mirrors the five built-ins for the
server-side synthesis path.
- dispatch_reminder() reads reminder_llm_persona and uses the
persona's system prompt; empty/unknown falls back to warm-neutral.
Esc handling
- Kebab menus and the provider picker intercept Esc in capture phase
so dismissing a popup no longer closes the whole Settings modal.
Accent tinting
- Scoped CSS rule across data-settings-panel=ai/services/added-models/
search/integrations/reminders for card h2 icons + the Added Models
sub-section icons.
Codex/Claude integration form
- No more auto-creation on form open — explicit Create token button.
- New tokens start with every scope granted; existing tokens move out
of the integration form into the API Permissions card.
- Setup reveal: copy buttons inline inside the token + setup code
blocks; shorter subtitle wording.
Misc visual polish
- Save/Test/Cancel uniformly accent-outlined and right-aligned on
every integration form.
- Provider logos render inline next to the search fallback selects
and the Deep Research Search dropdown.
- Trash icons in fallback rows bumped to 20x20 so they fill the 32px
button.
- Image generation default flipped to off.
Surface a lot of accumulated cookbook + UI work as a single non-agent
commit so the agent rework lands cleanly.
Highlights:
- Ollama as a first-class backend in the Cookbook:
* Download input accepts ollama-style names (name:tag) → backend=ollama
* /api/cookbook/ollama/library (cached scrape of ollama.com + curated
fallback so classic models like qwen2.5 stay reachable)
* "Browse Ollama library" toggle below Download with size chips
* Engine=Ollama in hwfit toolbar merges the Ollama library into the
main scan list as per-tag rows with the same Fit/Param/Quant/VRAM
columns; click → fills Download input
- API Tokens form added to Integrations panel (matching wired
loadTokens()/initTokenForm() that had no HTML)
- Serve panel polish: Advanced fold tightening (-8px nudges on vLLM
checks, Extra args, Spec row), n_cpu_moe + Split Mode controls
pulled up 8px to align with the row's checkboxes, GGUF File dropdown
exposed for Ollama backend, GPU re-render on Edit serve restore,
_forceBackend flag so saved serveState wins over backend detection,
cookbook:servers-changed CustomEvent so panels don't need refresh
- Models page redesign: Add Models row (URL + hidden API key reveal +
Type select + Scan/Ollama/Key/Test/Add icon buttons), Probe All +
Clear-offline buttons in Added Models toolbar, offline-pill removed
(opacity already conveys state), Engine dropdown gains Ollama option
- _ping_endpoint probes /v1/models then base, accepts 4xx as
reachable (vLLM returns 404 on bare /v1, fully working endpoints
were showing offline)
- Diagnosis card: × dismiss + Copy bundle buttons restored on the
serve error feedback card
- Orphan tmux sweep re-enabled behind a 60s rate-limit + background
Thread (off the main event loop) so dead serves get discovered
- cookbook_routes auto-register watchdog: drops the endpoint if the
serve session exits non-zero within the first ~3min
- ollama-rocm sidecar awareness in download wrapper (`docker exec
ollama-rocm ollama pull` when host ollama isn't installed)
- Skill extractor sets initial_status="published" when
auto_approve_skills pref is on (audit demotes later)
- Skill list / model list / cookbook scan misc polish
Replaces any Discord-specific reminder channel with a generic outbound
webhook channel. Users pick any saved Integration as the target and
supply a JSON payload template with {{title}} and {{message}}
placeholders — values are JSON-escaped before substitution. Works with
Discord, Slack, Teams, ntfy (JSON mode), or any service that accepts a
POST with a JSON body.
- `src/settings.py` — reminder_webhook_integration_id +
reminder_webhook_payload_template defaults
- `routes/note_routes.py` — webhook delivery block; Integration lookup,
template rendering, auth wiring; built-in preset defaults so
discord_webhook works out of the box without a configured template;
settings_override kwarg avoids test-button race condition
- `routes/auth_routes.py` — discord_webhook preset test handler
- `src/integrations.py` — discord_webhook preset with description +
example templates; hides auth/key fields in the Integration form
- `src/builtin_actions.py` — webhook_sent delivery check
- `src/tool_implementations.py` — webhook aliases + enum updated
- `static/index.html` — Webhook channel option; Integration picker +
payload template textarea
- `static/js/settings.js` — Integration list, populateWebhookIntegrations,
syncChannelRows, hints, load/save, auto-fill preset templates,
test-button override payload, hide auth/key for URL-auth presets

* feat(calendar): support multiple CalDAV accounts
Replaces the single CalDAV credential slot with a named account list so
users can sync both a personal and work calendar simultaneously.
- Add `account_id` column to `CalendarCal` + startup migration
- `_load_caldav_accounts()` in caldav_sync.py reads `caldav_accounts`
list from prefs, auto-migrating the legacy single `caldav` key on
first use (no user action required)
- `sync_caldav()` iterates all accounts and aggregates counts/errors
- `writeback_event()` resolves credentials via `CalendarCal.account_id`,
falling back to the first account for legacy rows
- New REST endpoints: GET/POST/PUT/DELETE `/api/calendar/config/accounts`
- Legacy GET/POST `/api/calendar/config` preserved for backward compat
- Settings UI: one card per account with Label, URL, Username, Password
fields; Test button works for both unsaved (inline creds) and saved
(by account_id) accounts; delete removes only that account
- Update test_caldav_url_hardening.py mock to include `_save_for_user`
and updated `_sync_blocking` signature
* fix(calendar): restore #2765 PK scoping and #2819 writeback URL validation
Two regressions introduced by the multi-account refactor:
1. PK collision (#2765): _stable_cal_id was back to hashing only the URL,
so two users — or one user with two accounts on the same server — would
collide on the primary key. Restore owner+account_id in the hash key
(format: "{owner}\n{account_id}\n{url}") and thread both values through
_sync_blocking → _writeback_blocking → push_event → find_remote_calendar
so the hash round-trips correctly on write-back.
2. URL validation dropped (#2819): _load_caldav_accounts imported
_save_for_user at function scope, causing an ImportError on test mocks
that only provide _load_for_user, which prevented writeback_event from
reaching the validate_caldav_url call. Move the import inside the
migration branch and wrap in try/except (best-effort save; next call
re-migrates from the still-present legacy key).
Update fake_writeback_blocking in test_caldav_writeback.py to accept the
new owner/account_id optional params.
* Make edge-docked windows resizable
Add draggable resize seams for left and right docked windows.
Keep the main chat area from getting too narrow and remember each window's dock width.
* Show emoji shortcodes as icons by default
Keep text-only emoji mode opt-in so model output like 😊 goes through the normal emoji renderer.
* Fix dock resize seams and left dock layout
Hide the resize seam when another floating modal is open, and keep the left-docked window from covering the chat area.
* Keep narrow modal tabs usable
* Fix split layout with both edge docks
* Fix left snap after right dock
* Enable left edge snap for all windows
* Tighten dock resize handle observers
* Use edge docking for settings window
* fix(calendar): expose source in calendar list and add per-calendar delete
- GET /api/calendar/calendars now includes source field so the frontend
can distinguish CalDAV collections from local calendars
- Add DELETE /api/calendar/calendars/{cal_id} to remove a specific
calendar and its events by owner-scoped ID
* fix(settings): show all CalDAV calendars in integrations list
Previously one card was shown for the CalDAV server connection regardless
of how many calendar collections had been synced. The Calendars page showed
them all; Settings did not.
- Fetch /api/calendar/calendars alongside existing requests and render
one card per source=caldav collection, falling back to the single
server-level card if nothing has synced yet
- Delete now targets the specific calendar by ID rather than clearing
the whole server config
- Confirm dialog shows the calendar name so the user can verify before
removing
* feat(mcp): add Streamable HTTP transport with OAuth 2.0
Odysseus could only reach MCP servers over stdio and SSE, so modern
remote servers like https://mcp.higgsfield.ai/mcp (Streamable HTTP,
gated behind OAuth) could not be connected.
Add an `http` transport that connects via the SDK's
streamablehttp_client and authenticates with the SDK's
OAuthClientProvider: RFC 9728 protected-resource discovery, RFC 8414
authorization-server metadata, Dynamic Client Registration,
authorization-code + PKCE, and token refresh. A small bridge
(src/mcp_oauth.py) connects the SDK's blocking callback to the existing
web callback route via an asyncio.Future keyed by the OAuth `state`,
and the dynamic client registration plus tokens persist per-server in a
new encrypted `oauth_tokens` column.
The connect runs as a bounded background task so the "Add server"
request returns immediately; redirect_handler publishes needs_auth +
auth_url to connection state as soon as discovery/DCR completes (which
can exceed the bounded wait), and the UI polls until connected. Remote
users finish via the existing paste-back flow. The Google OAuth path is
left unchanged.
- core/database.py: encrypted oauth_tokens column + migration
- src/mcp_oauth.py: OAuth provider, DB-backed TokenStorage, state registry
- src/mcp_manager.py: http dispatch, background connect, _connect_http
- routes/mcp_routes.py: http validation, needs_auth/auth_url, callback bridge
- static/js/settings.js: Streamable HTTP option + OAuth flow with polling
- tests: 5 new unit tests (transport dispatch, registry, token storage)
Verified against the live Higgsfield server: discovery, DCR (client_id
issued), loopback redirect accepted, and a PKCE authorization URL with
needs_auth status. No regressions (full suite delta is only the 5 added
passing tests).
* fix(mcp): address PR #1033 review feedback
- mcp_oauth: derive redirect URI from OAUTH_REDIRECT_BASE_URL/APP_PUBLIC_URL
(default http://localhost:7000) instead of hardcoding the port
- mcp_oauth: leave OAuth scope unset so the SDK derives it from the server's
WWW-Authenticate/protected-resource metadata; hardcoding an OIDC scope broke
non-OpenID MCP servers (verified: Higgsfield still gets its server-derived
scope)
- mcp_oauth: prune abandoned OAuth flows (_prune_stale + _pending_ts) so the
module-level registries can't grow unbounded
- mcp_oauth: persist tokens/client-info in a single DB session/commit
(_update) instead of a load+save double round-trip
- mcp_manager: cancel and drop the background connect task in
disconnect_server so a deleted server stops publishing status
- database: document why the oauth_tokens migration uses TEXT while the model
declares EncryptedText (encryption is applied at the Python layer)
- settings.js: surface persistent OAuth-poll failures and an explicit timeout
message instead of silently swallowing errors
- tests: cover the stale-flow pruning
* static/js/settings.js now shows an in-flight loading state on the buttons that fire requests:
* feat: round-limit handling — Continue affordance at the cap + configurable cap
When the agent loop runs out of rounds (per-message step cap, default 20)
while still actively using tools, it stopped silently mid-task. Now:
1. The loop emits a `rounds_exhausted` SSE event at the cap, and the UI shows
a "Continue" pill at the bottom of the chat that resumes the task from where
it left off. Repeated cap-hits each get a fresh Continue (multiple continues
in a row).
2. The cap is configurable in Settings → Agent ("Max steps per message"),
validated on the client, at the save endpoint, and at the read site.
- src/agent_loop.py: track `_exhausted_rounds` (set only when a full
tool-executing round completes on the last allowed round — i.e. the agent
wanted to keep going); emit `{"type":"rounds_exhausted","rounds":N}` (logged).
- routes/chat_routes.py: read `agent_max_rounds` (clamped 1..200), pass as
`max_rounds`; forward the new event through the SSE relay.
- routes/auth_routes.py: validate numeric settings on save (int + clamp;
agent_max_rounds 1..200, agent_max_tool_calls 0..1000; 400 on non-int).
- src/settings.py: default `agent_max_rounds = 20`.
- static/: Settings input + client-side clamp; the Continue pill (reuses the
existing .stopped-indicator / .continue-btn classes and theme vars
--border/--fg/--bg/--accent); appended to the chat container so it survives
the message re-render at stream finalize. chat.js cache version bumped.
* test: cover rounds_exhausted emission (cap-hit vs normal finish)
Drives the real stream_agent_loop with mocked LLM stream / tool exec / settings:
a tool block every round exhausts the cap and must emit rounds_exhausted; a
plain answer hits the done-break and must not. Guards the for/else logic.
Three converging fixes so the chat agent + external Codex/Claude skills can actually debug a crashed serve instead of staring at a post-crash neofetch banner:
* Serves now `tee` to /tmp/odysseus-tmux/SESSION.log on the host running them. Runner saves fds 3/4 before the tee and restores them right before `exec ${SHELL}`, so the post-crash interactive zsh banner does NOT pollute the log file.
* `tail_serve_output` (chat agent) and `/api/codex/cookbook/output/{sid}` (Codex+Claude skills) both prefer the persistent log file over the tmux pane. Pane is fallback for sessions predating the tee runner. Default tail bumped 150 -> 400.
* `list_served_models` "recent log" snippet seeks to the Traceback line instead of showing the last 6 lines (which was always the bash prompt).
Cookbook auto-adoption sweep on `/api/cookbook/tasks/status`: every 20s (rate-limited) the cookbook SSHes each configured server, finds `serve-*` / `cookbook-*` tmux sessions running an actual model process (vllm/python/llama-server/etc., filtered via `pane_current_command`), and writes them into state.tasks. So when the agent falls back to raw ssh+tmux, the session appears in the Cookbook UI on the next poll.
`serve_model` error path now reads `data["detail"]` in addition to `data["error"]` so the FastAPI HTTPException message ("Invalid characters in cmd") actually reaches the agent instead of being swallowed as a generic "Serve failed". Tool description updated to warn against `cd …`/`source …`/`&&` prefixes.
Intent-without-action supervisor in agent_loop: when the model writes "Let me tail the output" / "I'll check the logs" / "Let me investigate" and ends the turn without emitting a tool call, the loop injects a sharp system nudge ("You said you would X — DO IT NOW") and continues. Capped at 2 nudges per chat so a model that genuinely cannot use the tool does not pin the loop.
Codex/Claude skill parity: adds `/cookbook/cached`, `/cookbook/presets`, `/cookbook/preset/{name}`, `/cookbook/adopt` so external agents have the same surface as the chat agent. SKILL.md docs + odysseus_api.py wrapper updated for both bundles.
`adopt_served_model` promoted to the always-on tool set so the agent has a documented fallback when serve_model rejects a cmd.
Also various cookbook UI tweaks accumulated alongside the above (cookbook.js, cookbookRunning.js, cookbookServe.js, cookbook-diagnosis.js, settings.js, style.css).
- Claude Agent integration: AGENT_CONFIGS.claude, INTG_TYPES.claude,
setup_claude_routes + integrations/claude/ skill bundle. Wired in
app.py alongside the existing Codex integration; same scope-gated
/api/codex/* backend; agent form has new description so users know
it's setup for an external CLI, not an agent streamed inside Odysseus.
- Remove mark_email_boundaries action: not good enough yet. Stripped
from task UI, scheduler defaults, registry, tool schema, clear-cache
route. Added to RETIRED_HOUSEKEEPING_ACTIONS so existing rows + their
task_runs auto-purge on startup.
- Cookbook download reliability: "Reconnect" fix button in the crash
diagnosis runs _reconnectTask after probing has-session. 30s confirm
window before marking a download "done" — kills the Finished/Downloading
flicker when tmux briefly drops between captures.
- Mobile UX: tap anywhere on a note card body opens the editor;
Update button morphs to Archive when no text was edited; bell icon
accent-colored; chip-trashing notif pills fade so only the icon
rotates into the trash zone.
- Settings integrations: SVG-per-provider in email + API preset
dropdowns, custom drop-up-aware menus, accent sub-header icons
(IMAP/SMTP), consistent card styling between list + edit, contacts
Edit/Delete icons, agent form description copy.

* feat: add custom option for search result count in settings
* fix: enforce minimum and maximum values for custom search result count
* Ignore AltGr keystrokes in Ctrl+Alt keyboard shortcuts
Browsers report AltGr (right Alt on AZERTY/QWERTZ and most non-US
layouts, used to type @ # { } [ ] | \ and the euro sign) as
ctrlKey+altKey. The default keybinds map destructive actions to
Ctrl+Alt+<letter> (delete_session, new_session, incognito,
open_calendar), so a non-US user typing a special character could
silently fire them.
Guard the shortcut matcher, the editor keydown handler, and the rebind
capture with getModifierState('AltGraph'), which is true for AltGr but
false for a genuine left Ctrl+Alt. macOS is excluded: there the Option
key legitimately sets AltGraph and there is no AltGr/Ctrl+Alt collision
to guard against, so the guard would otherwise break Ctrl+Option /
Cmd+Option shortcuts (notably in Firefox).
The detection lives in one place — isAltGrEvent / IS_MAC in
static/js/platform.js — and all three call sites route through it, so the
guards can't drift apart.
The editor handler only skips the Ctrl+Alt chord block, so layout
shortcuts reachable via AltGr (e.g. [ ] brush size = AltGr+5/+8 on
AZERTY) keep working.
* Require Ctrl+Alt for the AltGr guard and consolidate keybind test marks
isAltGrEvent now also checks ctrlKey+altKey so it only suppresses the
"AltGr reported as Ctrl+Alt" collision; an event asserting AltGraph on
its own (a Linux ISO_Level3_Shift layout, a stray modifier) is left
alone. Pin it with test_isaltgr_false_when_altgraph_set_but_not_ctrl_alt.
Collapse the 12 per-test node skipif marks into one module-level
pytestmark, and note in platform.js why IS_MAC intentionally covers
iPad/iPhone and mirrors the isMac checks in calendar.js / sessions.js.
routes/mcp_routes.py declares POST /api/mcp/servers with FastAPI
Form(...) params. The Save handler in static/js/settings.js was
sending application/json, so the Form parser saw no fields and
returned 422 with "Field required" for every input — clicking Save
did nothing visible.
Build a FormData object and let the browser set the multipart
Content-Type. args/env are JSON-stringified per the controller
contract (defaults "[]" / "{}"); bad JSON still falls back to
defaults, same as before.
Also check r.ok and surface non-2xx in the form-status span — the
previous code never checked status, so a 422 looked like success.
Matches the FormData pattern already used in this file (uf-mcp-toggle,
~L4036) for the toggle-enable PATCH against the same controller.
