README

From the reviewed commit 298a67e ↗; it updates when the author re-pins.

Hermes Notch Plugin reads Hermes' local state database in a read-only transaction and presents a compact monitor in Atoll's notch UI. It never writes state.db or sends state to a remote service. When a turn starts, the notch may show one bounded, sanitized display-side request preview: text parts only, with obvious secret patterns redacted. It never exposes transcript bodies, tool arguments, provider-only content, or credentials.

What it does

  • Shows active turns, sessions that need attention, and recent session details.
  • Shows the actual session title with Complete in a brief sneak peek when a turn/session finishes. A confirmed lease release or durable ended_at boundary triggers it; a closed notch keeps rendering glyphs only.
  • Floors dashboard rewrites at one every 5 s so the tab stays well inside Atoll's per-bundle extension rate limit, then delivers the final state on a deferred wake.
  • Uses stable Atoll resource IDs and a single monitor process, so refreshes update the existing display instead of creating duplicates.
  • Watches SQLite and WAL changes with fswatch, then falls back to periodic refreshes if fswatch is unavailable.

Dummy-data media evidence

The media below was captured from the native Atoll surface with synthetic, display-only fixtures. It contains no real Hermes session titles, requests, transcripts, tool arguments, or desktop windows. The GIF is a timed native recording, not a slideshow; the PNGs are state captures.

Capability Evidence

One running turn and orbit notch-running-1.png, timed hermes-notch-demo.gif
Twelve running turns / two-digit count notch-running-12.png
Needs-action marker notch-needs-action.png
Completion title, Complete, zero, and retraction notch-complete.png, notch-idle.png, notch-hidden.png
Expanded multi-session list, selection, details, recent steps, and stats hermes-expanded-demo.png
Watcher fallback, pacing, lifecycle, transition detection, and read-only data path npm test and python3 tools/test-plugin-entrypoint.py (behavioral evidence; screenshots do not prove these nonvisual paths)

The capture manifests are notch-phases.manifest.json, hermes-notch-demo.manifest.json, and hermes-expanded-demo.manifest.json. Re-run the native captures with the current, already-running CuaDriver socket (discover it from ps; never hardcode an old socket):

node tools/demo-effects.js all --seconds 6 \
  --capture-dir "$HOME/.hermes/cache/scratch/atoll-effect-demo" \
  --socket "$CUDRIVER_SOCKET"
node tools/record-demo-gif.js --socket "$CUDRIVER_SOCKET"

# Resolve the exact Atoll pid/window and inspect its live AX labels first.
# The expanded capture never accepts screen coordinates.
cua-driver call list_windows --socket "$CUDRIVER_SOCKET" --json '{}'
cua-driver call get_window_state --socket "$CUDRIVER_SOCKET" --json \
  '{"pid":'$ATOLL_PID',"window_id":'$ATOLL_WINDOW_ID',"include_screenshot":false}'
node tools/capture-expanded-demo.js \
  --socket "$CUDRIVER_SOCKET" \
  --pid "$ATOLL_PID" \
  --window-id "$ATOLL_WINDOW_ID" \
  --tab-label "$ATOLL_TAB_AX_LABEL"

--tab-label must be the exact actionable AX label from that fresh get_window_state response. Selection uses CuaDriver's background AX path, not the real pointer, focus, browser, hotkeys, or permissions. If the correct Hermes tab is already expanded, omit --tab-label; the script asserts the synthetic session labels in the background and captures only after that assertion. If the exact window or AX state cannot be verified, it fails closed without producing a screenshot; open the correct tab yourself and retry. The expanded manifest records the asserted pid/window, selection route, and labels.

Requirements

  • macOS 14 or newer on a MacBook with a notch. Setup uses the maintained himanusia/Atoll fork, not the upstream repository.
  • Hermes Agent with its state database at ~/.hermes/state.db. Set HERMES_HOME if your Hermes home is elsewhere.
  • Node.js 22.5 or newer. The Hermes installer can install this plugin's pinned Node dependencies in its own plugin directory.
  • Homebrew fswatch is recommended for faster updates; periodic refresh still works without it.
  • Xcode 15 or newer is required only when Atoll is not already installed. There is currently no verified Atoll release asset for this fork, so setup builds the pinned fork source unsigned and does not claim notarization.

Install

With your AI agent (recommended)

Paste this single prompt into Claude Code, Codex, Cursor, Hermes, or another agent:

Install and set up https://github.com/himanusia/hermes-notch-plugin for me by following its README, then verify Hermes Notch Plugin status.

The README is written so an agent can install the Hermes plugin, ensure the maintained himanusia/Atoll fork is used, build it from the pinned source ref when no app is present, and verify the local monitor without replacing an existing Atoll installation.

Manual

Install and enable the Hermes plugin:

hermes plugins install himanusia/hermes-notch-plugin --enable

Accept the installer's separate prompt to install the plugin's Node dependencies. Hermes keeps them in the plugin directory. Then let the integrated setup choose the safe path:

hermes notch setup
hermes notch status

hermes notch setup uses https://github.com/himanusia/Atoll.git at immutable commit 3ad728b8c318a51a6098949241d2ca4b6b99e637. It builds DynamicIsland.xcodeproj / DynamicIsland with Xcode unsigned, signs the built app, and installs only to a new ~/Applications/Atoll.app. If an Atoll app already exists, setup detects it and never overwrites, relaunches, clicks permissions, resets permissions, changes xattrs, or uses sudo. Preview the plan first with hermes notch setup --dry-run.

After starting/configuring Atoll yourself and enabling its local extension API, run hermes notch status again. The monitor starts on the next Hermes session; start it immediately with hermes notch start. When Atoll asks for authorization, allow the extension bundle dev.hima.notch-plugins.

Avoid re-approving macOS permissions

macOS records Accessibility, Screen Recording, and folder grants against the app's designated requirement. An ad-hoc signature gets a cdhash requirement that changes on every build, so each update looks like a new app and macOS asks again. A stable local identity makes the requirement certificate-based instead:

# ad-hoc
designated => cdhash H"30487fa1a16135d08abbfb99ca48823c2cf5ef99"

# signed with one local identity
designated => identifier "com.Ebullioscopic.Atoll" and certificate root = H"46a744ddc047ff480787337f32bc505badac196d"

Create the identity once (it is self-signed, so it does not need to be trusted, and no system trust setting is touched):

mkdir -p ~/.hermes/cache/atoll-signing && cd ~/.hermes/cache/atoll-signing
openssl req -x509 -newkey rsa:2048 -nodes -sha256 -days 3650 \
  -keyout key.pem -out cert.pem -subj "/CN=Hermes Notch Local Signing/O=Himanusia Local Development" \
  -addext "basicConstraints=critical,CA:FALSE" -addext "keyUsage=critical,digitalSignature" \
  -addext "extendedKeyUsage=critical,codeSigning"
openssl pkcs12 -export -inkey key.pem -in cert.pem -name "Hermes Notch Local Signing" \
  -out identity.p12 -passout pass:temporary
security import identity.p12 -k ~/Library/Keychains/login.keychain-db -P temporary -T /usr/bin/codesign
rm -f key.pem identity.p12

security find-identity -p codesigning -v reports this identity as CSSMERR_TP_NOT_TRUSTED and counts zero valid identities. That is expected and harmless: codesign still signs with it and codesign --verify --deep --strict still passes.

Then run setup without extra flags. It prefers Hermes Notch Local Signing, falls back to any other identity in the keychain, and only signs ad-hoc when none exists:

hermes notch setup --dry-run          # shows the exact codesign command and the resolved identity
hermes notch setup
hermes notch setup --sign-identity "My Other Identity"

Switching an installed ad-hoc app to a certificate costs one re-approval of the permissions macOS already asked for. Rebuilding with the same identity afterwards keeps them.

Not notarized: distribution to other machines still needs an Apple Developer ID certificate and notarization. A Developer ID is a different identity from this local one; using it is enough for setup to prefer it automatically, since it is a valid keychain identity.

Manage the monitor

hermes notch status
hermes notch start
hermes notch stop
hermes notch restart

stop keeps the monitor off until the next Hermes session. Logs are written to ~/.hermes/logs/notch/hermes-atoll.log. The existing hermes atoll ... command remains a compatibility alias; the stable Hermes plugin identity is still hermes-atoll so enabled users keep working.

To remove the plugin:

hermes notch stop
hermes plugins remove hermes-atoll

Development

npm ci
npm test
python3 tools/test-plugin-entrypoint.py
python3 tools/test-notch-setup.py
hermes plugins doctor --ci .

The Node tests cover rendering, state transitions, host lifecycle, and SQLite/WAL watching. The Python smoke test checks Hermes hook and CLI registration without starting Atoll.
