AGENT ORCHESTRATION ORCHESTRATION

Sisyphus — self-hosted orchestrator for coding agents multi-agent design · tool scoping · MCP
servers and clients · sandboxing ·
personal · 2026 · Python 3.14 · 24k LOC · 1,852 tests permission gates · budgets
· goal → plan → workers (git worktrees) → reviewer → merge
· merge gate: repo's own check command, exit code bound to VOICE / S2S
commit SHA
· orchestrator: (thread + event) → one action; no model HTTP VAD · AEC · turn detection · barge-in ·
streaming STT/TTS · Whisper · edge-tts ·
in core PCM, ffmpeg
· 25 MCP tools, scoped per (task, role), bearer token per run
· sandbox: Seatbelt write/read deny, egress allowlist, credential APPLIED ML & EVALS

VOICE & SPEECH-TO-SPEECH
CODE
heare — realtime ambient voice assistant
Python · Kotlin · Bash · TypeScript · C++
personal · 2026 · Python · 12 packages · 21k LOC (ESP32) · FastAPI · SQLite · Docker ·
· PCM spine: VAD → STT → turn → LLM → TTS; no Pipecat GitHub Actions
· AEC: WebRTC AEC3, far-end reference, 10 ms blocks, 40–50
dB EDUCATION
· turn end: one monotonic deadline; two timers before → WUNU — B.A Computer Integrated
double answers Technologies, 2016–2020
· TTS: edge-tts MP3 → ffmpeg PCM, streaming, first chunk
before synthesis ends A L S O B U I LT ( P E R S O N A L )
· STT: Whisper large-v3 via Groq, uk/en/ru, hallucination filter
· barge-in while TTS plays pluglight — MagSafe cable as agent
status light · 8 agents · checksums,
APPLIED AI releases, CI
AgentLight — ESP32-C3 agent-state
reel-pipeline — phone footage → finished short video lamp · MCP server + Claude Code hooks
personal · 2026 · Python + Node ManualFlow — getevent + UiAutomator
· faster-whisper word-level timings · DeepFilterNet denoise → Maestro flows
· 1 LLM call per take → JSON schema; sha1 cache → life-as-a-service — KMP + FastAPI STT ·
deterministic output chose server Whisper over on-device
· floor plan: CubiCasa5K walls → own room segmentation Vosk
· evals: 15 takes · 40-take blind set · 4× determinism · 58 unit usbshka — native Swift menu bar app ·
