[v0.25] Sprint 23 -- Profile/Workspace/Model Coherence
April 3, 2026 | 423 tests
Features
- Profile-local workspace storage. Each named profile now stores its own
workspaces.jsonandlast_workspace.txtunder{profile_home}/webui_state/. Default profile continues using the global STATE_DIR for backward compat. - Profile switch returns defaults.
POST /api/profile/switchresponse now includesdefault_modelanddefault_workspacefrom the new profile's config.yaml, enabling one-round-trip state sync. - Session profile filter. Session sidebar filters to the active profile by default. "Show N from other profiles" toggle reveals sessions from all profiles, modeled on the existing archived toggle. Resets on profile switch.
Bug Fixes
- Model picker ignores profile on switch.
switchToProfile()now clears thehermes-webui-modellocalStorage key so the profile's default model applies instead of a stale preference from another profile. - Workspace list was global. Switching profiles no longer shows the wrong profile's workspaces.
DEFAULT_WORKSPACEwas a boot-time singleton. Now resolved dynamically through_profile_default_workspace().- Session list showed all profiles. Now filtered to active profile.
switchToProfile()didn't refresh workspaces or sessions. Now refreshes workspace list, session list, and resets profile filter on switch.
Architecture
api/workspace.pyrewritten with profile-aware path resolution.api/profiles.py:switch_profile()returnsdefault_modelanddefault_workspace.static/sessions.js: Profile filter with toggle UI.static/panels.js: Full cascade refresh on profile switch.- 8 new tests in
test_sprint23.py.
[v0.24] Sprint 22 -- Multi-Profile Support (Issue #28)
April 3, 2026 | 415 tests
Features
- Profile picker (topbar). Purple-accented chip with SVG user icon. Click to open dropdown listing all profiles with gateway status dots (green = running), model info, and skill count. Click any profile to switch; "Manage profiles" link opens the sidebar panel.
- Profiles management panel. New sidebar tab with full CRUD UI. Profile cards show name, model/provider, skill count, API key status, and gateway status badge. "Use" button switches profile, delete button removes non-default profiles (with confirmation).
- Profile creation. "+ New profile" form with name validation (
[a-z0-9_-]), optional "clone config from active" checkbox. Wraps the CLI'shermes_cli.profiles.create_profile(). - Profile deletion. Confirm dialog. Auto-switches to default if deleting the active profile. Blocked while agent is running.
- Seamless profile switching. No server restart. Profile switch updates
HERMES_HOME, patches module-level caches in hermes-agent'sskills_toolandcron/jobs, reloads.envAPI keys andconfig.yaml, refreshes the model dropdown, skills, memory, and cron panels. - Per-session profile tracking.
profilefield on Session records which profile was active at creation. Backward-compatible (nullfor old sessions).
Bug Fixes
- Hardcoded
~/.hermespaths. Memory read/write and model discovery used hardcoded paths. Now resolved throughget_active_hermes_home(). - Module-level path caching. hermes-agent modules snapshot
HERMES_HOMEat import time. Profile switch now monkey-patchesSKILLS_DIR,CRON_DIR,JOBS_FILE,OUTPUT_DIRso they track the active profile.
Architecture
- New
api/profiles.py: profile state management wrappinghermes_cli.profiles. Thread-safe (_profile_lock). Lazy imports avoid circular deps. api/config.py: module-levelcfgreplaced with reloadableget_config()/reload_config(). Dynamic_get_config_path()resolves through profile.api/streaming.py:HERMES_HOMEadded to env save/restore block.- Profile switch blocked while agent streams are active.
- 5 new API endpoints:
GET /api/profiles,GET /api/profile/active,POST /api/profile/switch,POST /api/profile/create,POST /api/profile/delete. - Zero modifications to hermes-agent code.
[v0.23] Sprint 21 -- Mobile Responsive + Docker
April 3, 2026 | 415 tests
Features
- Mobile responsive layout (Issue #21). Full mobile experience with
hamburger sidebar (slide-in overlay), bottom navigation bar (5-tab iOS
pattern), and files slide-over panel. Touch targets minimum 44px. Composer
positioned above bottom nav. Session clicks auto-close sidebar. Desktop
layout completely unchanged — all mobile elements hidden via
@media. - Docker support (Issue #7). Dockerfile (
python:3.12-slim), docker-compose.yml with named volume for state persistence, optional~/.hermesmount for agent features. Binds to127.0.0.1by default for security.
Bug Fixes (from review)
- CSS cascade broke mobile slide-in.
position:relativerules after the media query overrodeposition:fixedon mobile. Wrapped in@media(min-width:641px). - mobileSwitchPanel() always reopened sidebar. Chat tab now closes sidebar instead of reopening it over the main chat area.
- Dockerfile missing pip install. Added
pip install -r requirements.txt. - No .dockerignore. Added exclusions for
.git,tests/,.env*. - docker-compose tilde expansion. Changed
~/.hermesdefault to${HOME}/.hermes(Docker Compose doesn't shell-expand~).
Architecture
- Mobile navigation functions in
boot.js:toggleMobileSidebar(),closeMobileSidebar(),toggleMobileFiles(),mobileSwitchPanel(). sessions.js:closeMobileSidebar()called after session click.- 69 new CSS lines in
@media(max-width:640px)block. - New files:
Dockerfile,docker-compose.yml,.dockerignore.
[v0.22] Sprint 20 -- Voice Input + Send Button Polish
April 3, 2026 | 415 tests
Features
- Voice input via Web Speech API. Microphone button in the composer. Tap to start recording, tap again (or send) to stop. Live interim transcription appears in the textarea. Auto-stops after ~2s of silence. Final text stays editable before sending. Appends to existing textarea content rather than replacing it. Button hidden when browser doesn't support Web Speech API. No API keys, no external libraries, no server changes. Works in Chrome, Edge, Safari (partial). Firefox unsupported (button stays hidden).
- Send button polish. Send button redesigned as a 34px icon-only circle with upward arrow SVG. Hidden by default — appears with pop-in spring animation when textarea has content or files are attached. Disappears on send or when content is cleared. Hidden while agent is responding. Blue fill (#7cb9ff) with glow, scale hover/active for tactile feedback.
Architecture
- Voice input IIFE in
boot.js: SpeechRecognition lifecycle withcontinuous=false,interimResults=true, error handling viashowToast(). _prefixvariable snapshots existing textarea content on recording start so dictation appends rather than overwrites.btnSend.onclickstops active recognition before sending (send guard).- CSS:
.mic-btn,.mic-btn.recording(red pulse),.mic-status,.mic-dot,@keyframes mic-pulse. updateSendBtn()inui.jstracks textarea content, pending files, and busy state. Hooked intosetBusy(),renderTray(),autoResize(), and input event listener.- CSS:
.send-btnredesigned (circle, glow),.send-btn.visible+@keyframes send-pop-in(spring animation).
Tests
- 52 new tests in
test_sprint20.py: voice input HTML, CSS, JS, append behaviour, error handling, regressions. - 33 new tests in
test_sprint20b.py: send button HTML, CSS, JS, animation, visibility logic, regressions. Total: 415 tests.
[v0.21] Sprint 19 -- Auth + Security Hardening
April 3, 2026 | 328 tests
Features
- Password authentication (Issue #23). Optional password auth, off by default.
Enable via
HERMES_WEBUI_PASSWORDenv var or Settings panel. Password-only (single-user app). Signed HMAC HTTP-only cookie with 24h TTL. Minimal dark-themed login page at/login. API calls without auth return 401; page loads redirect. Newapi/auth.pymodule with hashing, verification, session management. - Security headers. All responses now include
X-Content-Type-Options: nosniff,X-Frame-Options: DENY,Referrer-Policy: same-origin. - POST body size limit. Non-upload POST bodies capped at 20MB via
read_body(). - Settings panel additions. "Access Password" field and "Sign Out" button (only visible when auth is active).
Architecture
- New
api/auth.py: password hashing (SHA-256 + STATE_DIR salt), signed cookies, auth middleware, public path allowlist. - Auth check in
server.pydo_GET/do_POST before routing. password_hashadded to_SETTINGS_DEFAULTS.
Tests
- 10 new tests in
test_sprint19.py: auth status, login flow, security headers, cache-control, settings password field, request size limit. Total: 328 tests (328 passing).
[v0.20] Sprint 18 -- File Preview Auto-Close + Thinking Display + Workspace Tree
April 3, 2026 | 318 tests
Features
- File preview auto-close on directory navigation. When viewing a file in
the right panel and navigating directories (breadcrumbs, up button, folder
clicks), the preview now automatically closes instead of showing stale
content.
clearPreview()extracted as named function and called fromloadDir(). Unsaved preview edits prompt for confirmation before discarding. - Thinking/reasoning display. Assistant messages with structured content
arrays containing
type:'thinking'ortype:'reasoning'blocks (Claude extended thinking, o3 reasoning) now render as collapsible gold-themed cards above the response text. Collapsed by default. Click the header to expand and see the model's reasoning process. Usesesc()on all content for XSS safety. - Workspace tree view (Issue #22). Directories expand/collapse in-place
with toggle arrows. Single-click toggles a directory open/closed. Double-click
navigates into it (breadcrumb view). Subdirectory contents fetched lazily from
the API and cached in
S._dirCache. Nesting depth shown via indentation. Empty directories show "(empty)" placeholder. Breadcrumb navigation still works alongside the tree view.
Bug Fixes
- Stale tree cache on session switch.
S._dirCacheandS._expandedDirsare now cleared when navigating to the root directory, preventing session B from showing session A's cached file listings. - clearPreview() discards unsaved edits. Navigation now checks
_previewDirtyand prompts before discarding unsaved preview changes.
Architecture
clearPreview()extracted from inline handler to named function inboot.js.- Thinking card styles added to
style.css(gold-themed, collapsible). - Tree toggle and empty-directory styles added to
style.css.
[v0.19] Sprint 17 -- Workspace Polish + Slash Commands + Settings
April 3, 2026 | 318 tests
Features
- Workspace breadcrumb navigation. Clicking into subdirectories now shows a
breadcrumb path bar (e.g.
~ / src / components) with clickable segments to navigate back. An "up" button appears in the panel header when inside a subdirectory. File operations (rename, delete, new file/folder) stay in the current directory instead of jumping back to root. Foundation for Issue #22 (tree view). - Slash commands. Type
/in the composer to see an autocomplete dropdown of built-in commands. Newcommands.jsmodule with command registry. Built-in commands:/help,/clear,/model <name>,/workspace <name>,/new. Arrow keys navigate, Tab/Enter select, Escape closes. Unrecognized commands pass through to the agent normally. - Send key setting (Issue #26). New setting in Settings panel to choose
between Enter (default) and Ctrl/Cmd+Enter as the send key. Persisted to
settings.jsonvia the existing settings API. Setting loads on boot. Server-side validation ensures only valid values (enter,ctrl+enter).
Architecture
- New
static/commands.jsmodule (7th JS module): command registry, parser, autocomplete dropdown, and built-in command handlers. send_keyadded to_SETTINGS_DEFAULTSinapi/config.pywith enum validation (_SETTINGS_ENUM_VALUESrejects unknown values server-side).S.currentDirstate tracking added toui.jsfor workspace navigation.
Tests
- 6 new tests in
test_sprint17.py: send_key default, round-trip save with cleanup, invalid value rejection, unknown key ignored, commands.js served, workspace root listing. Total: 318 passed.
[v0.18.1] Safe HTML Rendering + Sprint 16 Tests
April 2, 2026 | 289 tests
Features
- Safe HTML rendering in AI responses. AI models sometimes emit HTML tags
(
<strong>,<em>,<code>,<br>) in their responses. Previously these showed as literal escaped text. A new pre-pass inrenderMd()converts safe HTML tags to markdown equivalents before the pipeline runs. Code blocks and backtick spans are stashed first so their content is never touched. inlineMd()helper. New function for processing inline formatting inside list items, blockquotes, and headings. The old code calledesc()directly, which escaped tags that had already been converted by the pre-pass.- Safety net. After the full pipeline, any HTML tags not in the output
allowlist (
SAFE_TAGS) are escaped viaesc(). XSS fully blocked -- 7 attack vectors tested. - Active session gold style. Active session uses gold/amber (
#e8a030) instead of blue, matching the logo gradient. Project border-left skipped when active (gold always wins).
Tests
- 74 new tests in
test_sprint16.py: static analysis (6), behavioral (10), exact regression (1), XSS security (7), edge cases (51). Total: 289 passed.
[v0.18] Sprint 16 -- Session Sidebar Visual Polish
April 2, 2026 | 237 tests
Features
- SVG action icons. Replaced all emoji HTML entities (star, folder, box,
duplicate, trash) with monochrome SVG line icons that inherit
currentColor. Consistent rendering across macOS, Linux, and Windows. Defined in a top-levelICONSconstant insessions.js. - Action buttons overlay. All session action buttons (pin, move, archive,
duplicate, trash) wrapped in a
.session-actionscontainer withposition:absolute. Titles now use full available width instead of being truncated by invisible buttons. Actions appear on hover with a gradient fade from the right edge. Overlay auto-hides during inline rename via:has(.session-title-input). - Pin indicator. Small gold filled-star icon rendered inline before the title only when pinned. Unpinned sessions get full title width with zero space reservation.
- Project border indicator. Sessions assigned to a project show a colored left border matching the project color, replacing the old always-visible blue folder button.
Bug Fixes
- Session title truncation. Action icons reserved ~30px of space even when invisible, truncating titles. Fixed by overlay container approach.
- Folder button felt sticky. Replaced
.has-projectpersistent blue button with colored left border. Folder button now only appears in hover overlay.
[v0.17.3] Bug Fixes
April 2, 2026
Bug Fixes
- NameError crash in model discovery.
logger.debug()was called in the custom endpointexceptblock inconfig.py, butloggerwas never imported. Every failed custom endpoint fetch crashed withNameError, returning HTTP 500 for/api/models. Replaced with silentpasssince unreachable endpoints are expected. (PR #24) - Project picker clipping and width. Picker was clipped by
overflow:hiddenon ancestor elements. Width calculation improved with dynamic sizing (min 160px, max 220px). Event listenerclosehandler moved after DOM append to fix reference-before-definition. Reorderedpicker.remove()beforeremoveEventListenerfor correct cleanup. (PR #25)
[v0.17.2] Model Update
April 2, 2026
Enhancements
- GLM-5.1 added to Z.AI model list. New model available in the dropdown for Z.AI provider users. (Fixes #17)
[v0.17.1] Security + Bug Fixes
April 2, 2026 | 237 tests
Security
- Path traversal in static file server.
_serve_static()now sandboxes resolved paths insidestatic/via.relative_to(). PreviouslyGET /static/../../.hermes/config.yamlcould expose API keys. - XSS in markdown renderer. All captured groups in bold, italic, headings,
blockquotes, list items, table cells, and link labels now run through
esc()beforeinnerHTMLinsertion. - Skill category path traversal. Category param validated to reject
/and..to prevent writing outside~/.hermes/skills/. - Debug endpoint locked to localhost.
/api/approval/inject_testreturns 404 to any non-loopback client. - CDN resources pinned with SRI hashes. PrismJS and Mermaid tags now have
integrity+crossoriginattributes. Mermaid pinned to@10.9.3. - Project color CSS injection. Color field validated against
^#[0-9a-fA-F]{3,8}$to preventstyle.backgroundinjection. - Project name length limit. Capped at 128 chars, empty-after-strip rejected.
Bug Fixes
- OpenRouter model routing regression.
resolve_model_provider()was incorrectly stripping provider prefixes from OpenRouter model IDs (e.g.openai/gpt-5.4-minibecamegpt-5.4-miniwith provideropenai), causing AIAgent to look for OPENAI_API_KEY and crash. Fix: only strip prefix whenconfig.providerexplicitly matches that direct-API provider. - Project picker invisible. Dropdown was clipped by
.session-itemoverflow:hidden. Now appended todocument.bodywithposition:fixed. - Project picker stretched full width. Added
max-width:220px; width:max-contentto constrain the fixed-positioned picker. - No way to create project from picker. Added "+ New project" item at the bottom of the picker dropdown.
- Folder button undiscoverable. Now shows persistently (blue, 60% opacity) when session belongs to a project.
- Picker event listener leak.
removeEventListeneradded to all picker item onclick handlers. - Redundant sys.path.insert calls removed. Two cron handler imports no longer prepend the agent dir (already on sys.path via config.py).
[v0.17] Sprint 15 -- Session Projects + Code Copy + Tool Card Toggle
April 1, 2026 | 237 tests
Features
- Session projects. Named groups for organizing sessions. A project filter
bar (subtle chips) sits between the search input and the session list. Each
project has a name and color. Click a chip to filter; "All" shows everything.
Create inline (+), rename (double-click), delete (right-click). Assign sessions
via folder icon button with dropdown picker. Projects stored in
projects.json. Session model gainsproject_idfield. 5 new API endpoints. - Code block copy button. Every code block gets a "Copy" button in the language header bar (or top-right for plain blocks). Click copies to clipboard, shows "Copied!" for 1.5s.
- Tool card expand/collapse. When a message has 2+ tool cards, "Expand all / Collapse all" toggle appears above the card group.
[v0.16.2] Model List Updates + base_url Passthrough
April 1, 2026 | 247 tests
Bug Fixes
- MiniMax model list updated. Replaced stale ABAB 6.5 models with current MiniMax-M2.7, M2.7-highspeed, M2.5, M2.5-highspeed, M2.1 lineup matching hermes-agent upstream. (Fixes #6)
- Z.AI/GLM model list updated. Replaced GLM-4 series with current GLM-5, GLM-5 Turbo, GLM-4.7, GLM-4.5, GLM-4.5 Flash lineup.
- base_url passthrough to AIAgent.
resolve_model_provider()now readsbase_urlfrom config.yaml and passes it to AIAgent, so providers with custom endpoints (MiniMax, Z.AI, local LLMs) route to the correct API.
[v0.16.1] Community Fixes -- Mobile + Auth + Provider Routing
April 1, 2026 | 247 tests
Community contributions from @deboste, reviewed and refined.
Bug Fixes
- Mobile responsive layout. Comprehensive
@media(max-width:640px)rules for topbar, messages, composer, tool cards, approval cards, and settings modal. Uses100dvhwith100vhfallback to fix composer cutoff on mobile browsers. Textareafont-size:16pxprevents iOS/Android auto-zoom on focus. - Reverse proxy basic auth support. All
fetch()andEventSourceURLs now constructed vianew URL(path, location.origin)to strip embedded credentials per Fetch spec.credentials:'include'on fetch,withCredentials:trueon EventSource ensure auth headers are forwarded through reverse proxies. - Model provider routing. New
resolve_model_provider()helper inapi/config.pystrips provider prefix from dropdown model IDs (e.g.anthropic/claude-sonnet-4.6→claude-sonnet-4.6) and passes the correctproviderto AIAgent. Handles cross-provider selection by matching against known direct-API providers.
[v0.16] Sprint 14 -- Visual Polish + Workspace Ops + Session Organization
March 30, 2026 | 233 tests
Features
- Mermaid diagram rendering. Code blocks tagged
mermaidrender as diagrams inline. Mermaid.js loaded lazily from CDN on first encounter. Dark theme with matching colors. Falls back to code block on parse error. - Message timestamps. Subtle HH:MM time next to each role label. Full
date/time on hover tooltip. User messages get
_tsfield when sent. - File rename. Double-click any filename in workspace panel to rename
inline.
POST /api/file/renameendpoint with path traversal protection. - Folder create. Folder icon button in workspace panel header. Prompt
for name,
POST /api/file/create-direndpoint. - Session tags. Add
#tagto session titles. Tags shown as colored chips in sidebar. Click a tag to filter the session list. - Session archive. Archive icon on each session. Archived sessions
hidden by default; "Show N archived" toggle at top of list. Backend
POST /api/session/archivewitharchivedfield on Session model.
Bug Fixes
- Date grouping fix. Session list groups (Today/Yesterday/Earlier) now
use
created_atinstead ofupdated_at, preventing sessions from jumping between groups when auto-titling touchesupdated_at.
[v0.15] Sprint 13 -- Alerts + Session QoL + Polish
March 30, 2026 | 221 tests
Features
- Cron completion alerts. New
GET /api/crons/recentendpoint. UI polls every 30s (pauses when tab is hidden). Toast notification per completion with status icon. Red badge count on Tasks nav tab, cleared when tab is opened. - Background agent error alerts. When a streaming session errors out and the user is viewing a different session, a persistent red banner appears above the messages: "Session X has encountered an error." View button navigates, Dismiss clears.
- Session duplicate. Copy icon on each session in the sidebar (visible on hover). Creates a new session with the same workspace and model, titled "(copy)".
- Browser tab title.
document.titleupdates to show the active session title (e.g. "My Task -- Hermes"). Resets to "Hermes" when no session is active.
Bug Fixes
- Click guard added for duplicate button to prevent accidental session navigation.
[v0.14] Sprint 12 -- Settings Panel + Reliability + Session QoL
March 30, 2026 | 211 tests
Features
- Settings panel. Gear icon in topbar opens slide-in overlay. Persist default
model and workspace server-side in
settings.json. Server reads on startup. - SSE auto-reconnect. When EventSource drops mid-stream, attempts one reconnect
using the same stream_id after 1.5s. Shared
_wireSSE()function eliminates handler duplication. - Pin sessions. Star icon on each session. Pinned sessions float to top of sidebar under a gold "Pinned" header. Persisted in session JSON.
- Import session from JSON. Upload button in sidebar. Creates new session with fresh ID from exported JSON file.
Bug Fixes
models.pyuses_cfg.DEFAULT_MODELmodule reference sosave_settings()changes take effect fornew_session().- Full-scan fallback sort in
all_sessions()now accounts for pinned sessions. save_settings()whitelists known keys only, rejecting arbitrary data.- Escape key closes settings overlay.
[v0.13] Sprint 11 -- Multi-Provider Models + Streaming Smoothness
March 30, 2026 | 201 tests
Features
- Multi-provider model support. New
GET /api/modelsendpoint discovers configured providers fromconfig.yaml,auth.json, and API key environment variables. The model dropdown now populates dynamically from whatever providers the user has set up (Anthropic, OpenAI, Google, DeepSeek, Nous Portal, OpenRouter, etc.). Falls back to the hardcoded OpenRouter list when no providers are detected. Sessions with unlisted models auto-add them to the dropdown. - Smooth scroll pinning. During streaming, auto-scroll only when the user is near the bottom of the message area. If the user scrolls up to read earlier content, new tokens no longer yank them back down. Pinning resumes when they scroll back to the bottom.
Architecture
- Routes extracted to api/routes.py. All 49 GET/POST route handlers moved from server.py
into
api/routes.py(802 lines). server.py is now a 76-line thin shell: Handler class with structured logging, dispatch tohandle_get()/handle_post(), andmain(). Completes the server split started in Sprint 10. - Cleaned up duplicate dead-code routes that existed in the old
do_GET(skills/save, skills/delete, memory/write were duplicated in both GET and POST handlers).
Bug Fixes
- Regression tests updated for new route module structure.
[v0.12.2] Concurrency + Correctness Sweeps
March 31, 2026 | 190 tests
Two systematic audits of all concurrent multi-session scenarios. Each finding became a regression test so it cannot silently return.
Sweep 1 (R10-R12)
- R10: Approval response to wrong session.
respondApproval()usedS.session.session_id-- whoever you were viewing. If session A triggered a dangerous command requiring approval and you switched to B then clicked Allow, the approval went to B's session_id. Agent on A stayed stuck. Fixed: approval events tag_approvalSessionId;respondApproval()uses that. - R11: Activity bar showed cross-session tool status. Session A's tool
name appeared in session B's activity bar while you were viewing B. Fixed:
setStatus()in the tool SSE handler is now inside theactiveSidguard. - R12: Live tool cards vanished on switch-away and back. Switching back to
an in-flight session showed empty live cards even though tools had fired.
Fixed:
loadSession()INFLIGHT branch now restores cards fromS.toolCalls.
Sweep 2 (R13-R15)
- R13: Settled tool cards never rendered after response completes.
renderMessages()has a!S.busyguard on tool card rendering. It was called withS.busy=truein the done handler -- tool cards were skipped every time. Fixed:S.busy=falseset inline beforerenderMessages(). - R14: Wrong model sent for sessions with unlisted model.
send()used$('modelSelect').valuewhich could be stale if the session's model isn't in the dropdown. Fixed: now usesS.session.model || $('modelSelect').value. - R15: Stale live tool cards in new sessions.
newSession()didn't callclearLiveToolCards(). Fixed.
[v0.12.1] Sprint 10 Post-Release Fixes
March 31, 2026 | 177 tests
Critical regressions introduced during the server.py split, caught by users and fixed immediately.
uuidnot imported in server.py --chat/startreturned 500 (NameError) on every new messageAIAgentnot imported in api/streaming.py -- agent thread crashed immediately, SSE returned 404has_pendingnot imported in api/streaming.py -- NameError during tool approval checksSession.__init__missingtool_callsparam -- 500 on any session with tool history- SSE loop did not break on
cancelevent -- connection hung after cancel - Regression test file added (
tests/test_regressions.py): 10 tests, one per introduced bug. These form a permanent regression gate so each class of error can never silently return.
[v0.12] Sprint 10 -- Server Health + Operational Polish
March 31, 2026 | 167 tests
Post-sprint Bug Fixes
- SSE loop now breaks on
cancelevent (was hanging after cancel) setBusy(false)now always hides the Cancel buttonS.activeStreamIdproperly initialized in the S global state object- Tool card "Show more" button uses data attributes instead of inline JSON.stringify (XSS/parse safety)
- Version label updated to v0.2
Session.__init__accepts**kwargsfor forward-compatibility with future JSON fields- Test cron jobs now isolated via
HERMES_HOMEenv var in conftest (no more pollution of real jobs.json) last_workspacereset after each test in conftest (prevents workspace state bleed between tests)- Tool cards now grouped per assistant turn instead of piled before last message
- Tool card insertion uses
data-msg-idxattribute correctly (wasmsgIdx, matching HTML5 dataset API)
Architecture
- server.py split into api/ modules. 1,150 lines -> 673 lines in server.py.
Extracted modules:
api/config.py(101),api/helpers.py(57),api/models.py(114),api/workspace.py(77),api/upload.py(77),api/streaming.py(187). server.py is now the thin routing shell only. All business logic is independently importable.
Features
- Background task cancel. Red "Cancel" button appears in the activity bar while a task
is running. Calls
GET /api/chat/cancel?stream_id=X. The agent thread receives a cancel event, emits a 'cancel' SSE event, and the UI shows "Task cancelled." in the conversation. Note: a tool call already in progress (e.g. a long terminal command) completes before the cancel takes effect -- same behavior as CLI Ctrl+C. - Cron run history viewer. Each job in the Tasks panel now has an "All runs" button. Click to expand a list of up to 20 past runs with timestamps, each collapsible to show the full output. Click again to hide.
- Tool card UX polish. Three improvements:
- Pulsing blue dot on cards for in-progress tools (distinct from completed cards)
- Smart snippet truncation at sentence boundaries instead of hard byte cutoff
- "Show more / Show less" toggle on tool results longer than 220 chars
[v0.11] Sprint 9 -- Codebase Health + Daily Driver Gaps
March 31, 2026 | 149 tests
The sprint that closed the last gaps for heavy agentic use.
Architecture
- app.js replaced by 6 modules.
app.jsis deleted. The browser now loads 6 focused files:ui.js(530),workspace.js(132),sessions.js(189),messages.js(221),panels.js(555),boot.js(142). The modules are a superset of the original app.js (two functions --loadTodos,toolIcon-- were added directly to the modules after the split). No single file exceeds 555 lines.
Features
- Tool call cards inline. Every tool Hermes uses now appears as a collapsible card in the conversation between the user message and the response. Live during streaming, restored from session history on reload. Shows tool name, preview, args, result snippet.
- Attachment metadata persists on reload. File badges on user messages survive page refresh. Server stores filenames on the user message in session JSON.
- Todo list panel. New checkmark tab in the sidebar. Shows current task list parsed from the most recent todo tool result in message history. Status icons: pending (○), in-progress (◉), completed (✓), cancelled (✗). Auto-refreshes when panel is active.
- Model preference persists. Last-used model saved to localStorage. Restored on page load. New sessions inherit it automatically.
Bug Fixes
- Tool card toggle arrow only shown when card has expandable content
- Attachment tagging matches by message content to avoid wrong-turn tagging
- SSE tool event was missing
argsfield /api/sessionGET was not returningtool_calls(history lost on reload)
[v0.10] Sprint 8 -- Daily Driver Finish Line
March 31, 2026 | 139 tests
Features
- Edit user message + regenerate. Hover any user bubble, click the pencil icon. Inline textarea, Enter submits, Escape cancels. Truncates session at that point and re-runs.
- Regenerate last response. Retry icon on the last assistant bubble only.
- Clear conversation. "Clear" button in topbar. Wipes messages, keeps session slot.

Bug Fixes
- Reconnect banner false positive on normal loads (90-second window)
- Session list clipping on short screens
- Favicon 404 console noise (server now returns 204)
- Edit textarea auto-resize on open
- Send button guard while inline edit is active
- Escape closes dropdown, clears search, cancels active edit
- Approval polling not restarted on INFLIGHT session switch-back
- Version label updated to v0.10
Hotfix: Message Queue + INFLIGHT
- Message queue. Sending while busy queues the message with toast + badge. Drains automatically on completion. Cleared on session switch.
- Message stays visible on switch-away/back. loadSession checks INFLIGHT before server fetch, so sent message and thinking dots persist correctly.
