A same-day, same-operator, real-workload comparison. Both agents were driven by Alex K. Chen during the Sundai RSI Hack: Harnesses (Aug 30, 2026) — Codex for deep synthesis/writing, Hermes for agentic tool work (log mining, forum posting, uploads, web edits). Data sources: Codex rollout token_count records (~/.codex/sessions/2026/08/30/), Hermes session_model_usage DB (~/.hermes/state.db), Nous Portal account API.

Companion to the PAF gist (OpenBCI Cyton EEG) and the Muse vs Cyton comparison. This one is fNIRS, not EEG — blood oxygenation, not electrical activity. Session date 2025-08-10 (the hackathon period; sessions driven via Windsurf/Antigravity agent sessions, scripts in the companion repo).

Companion to the PAF neuromodulation gist and the wearable data gist. Thread: ClawInstitute music-neurofeedback report.
I built a live music-neurofeedback system around an OpenBCI Cyton that streams EEG online in real time, computes PAF, alpha/theta, gamma/delta, and 1/f falloff, aligns Spotify track switches to before/after EEG windows, and saves labeled screenshots for each song change. I also added webcam-based eye-state/event tagging and manual annotations for nicotine, sleep, sustained focus, and later drowsiness. Over roughly 2.4 hours, the EEG suggests my recent state became less alert but cleaner: compared with my earlier “in the zone” block, the later drowsy window showed an inferred alertness/focus drop of about 28%, while artifact burden fell and signal cleanliness improved. Since the drowsiness onset, I changed Spotify tracks 20 times with a median gap of 31s, which I’m treating as a behavioral marker of reduced engagement. The system is already public and remotely viewable, so the next step is to let outside collaborators suggest track changes in real

Like other people who post their health data publicly, here is my complete wearable analysis: 2,945 days of steps (2011–2024), 521 nights of HRV, 1,652 days of heart rate, 1,253 nights of sleep, and 193 Whoop sleep nights — with every data-quality bug that almost fabricated false findings documented.
Distilled from my Codex agent session logs (March 2026). Devices: OpenBCI Cyton (gold cup electrodes, forehead/hairline + mastoid reference), FRENZ brainband (FRENZL70 earable), NeoSense Smartbuds, Arduino UNO R4 + ULN2003/28BYJ-48 stepper as BCI actuator. Metrics throughout: PAF (peak alpha frequency), alpha/theta ratio (ATR), gamma/delta, 1/f (aperiodic) slope + r², artifact rate.
Goal: drive a stepper motor from live EEG band dynamics — speed/direction follow brain state ("feel the synchrony").
/dev/cu.usbmodemDC5475EAE5A42, ULN2003 driver, 28BYJ-48 stepper. Note: an Arduino Uno died from overheating mid-experiments (shared-ground/5V miswire into ULN2003 suspected) — code was safe.frenz_ble_motor_live.py): BLE connect to FRENZL70 → compute ATR, PAF

Personal note: This is the beginning of turning selected, consented parts of my life and work into a long-form personal context and harness-engineering project, initially grounded in my Claude and Codex conversations. I had only about five concentrated hours for the hack, so it is not polished—but it supplied the activation energy for future harness and agent-engineering projects across my broader “memespace,” which makes the work disproportionately worthwhile. It also produces a starting template for bringing parts of Mathilde Papillo
