### Roborock — in_progress
Building a dependable assistant around an existing Roborock vacuum: a standalone MCP server, Apple on-device language processing, Telegram interaction, cleaning-history analysis, and confirmation-gated actions. The journey covers data reliability, asyncio/MQTT integration, small-model limitations, and the separation of reusable robot tools from the personal assistant. Public MCP repository: https://github.com/kerandia/roborock-mcp. The assistant remains unpublished; scheduling, presence integration, and proactive job supervision are planned, not implemented.

### SLM Confidence Layer — in_progress
Measuring how much to trust a small model's answer. Two students distilled from a 120B teacher onto Qwen3-0.6B, an oracle-and-probes method that labels invented inputs for free, calibrated confidence heads read from the model's own logprobs, a calibration table for GLiNER2.5's built-in scores, and the router economics of verification cost at a fixed escaped-error rate. Two agents, Claude and Codex, work one repo.

### CALLED IT — A Personal Decision Calendar From Prediction Markets — In Progress
CALLED IT turns prediction markets into a personal decision calendar: when the things you care about actually get decided, what the crowd currently expects, and whether that lands before or after what you have planned.
WHY THIS SHAPE
The project started as a cross-exchange arbitrage feed, became a Co-Star-style daily reading, and landed here. The pivot that mattered: prose readings that stated a mechanism but refused to give magnitudes or advice were defensible and useless — "rate expectations reach you through your variable rate" gives a reader nothing to do or even to watch. A date carries…

### Maproom — Agent-Published Interactive Maps — In Progress
Maproom is an agent-facing artifact host: typed place data in, a stable shareable interactive map URL out. Agents can publish maps without building bespoke frontend code, while Maproom handles validation, geocoding, secure rendering, immutable versions, and public delivery.
Current stack: Cloudflare Workers + Hono + TypeScript, D1 for canonical data and registry state, private R2 for immutable rendered HTML, KV only for geocoding cache, MapLibre with OpenFreeMap, and shared Zod schemas for REST and future MCP tools.
Current milestone: Phase 1 publish pipeline is complete. Next product capab…

### Agent Harnesses — Dynamic Tools & Self-Improving Runtimes — active
A practical project for designing, building, and evaluating reusable agent harnesses. The project combines three complementary ideas: (1) scalable tool calling through a searchable tool registry and lazy loading, where an agent starts with core tools plus search_tools and loads only relevant full schemas; (2) harness engineering as the execution layer around a base model, including plan-execute-observe-test-improve loops, persistent filesystem state, sub-agents, permissions, trajectory analysis, evaluation, and bounded self-improvement; and (3) Schema-style mechanism discovery, where the agen…

### Health Agent — Calorie Tracking — In Progress
A multi-tenant personal health agent that lives in Telegram. First vertical: calorie tracking — log meals by text or photo, get kcal/macro estimates, personalized targets from onboarding, and a web dashboard with an Apple-Watch-style calorie calendar. Built on Flue (harness), MiniMax-M2.5 via Nebius, Upstash (Redis/Vector/Box), Next.js on Vercel, and Google Cloud Run. Roadmap extends to voice logging, subscriptions, and broader health domains (biological age, calendar).

### Hermes Operator Layer — In Progress
A platform concept for spawning dedicated Hermes-operated business agents. A business owner enters business context, delegation goals, tools, authority level, and integrations; Hermes compiles operating context, creates a delegation contract, provisions a customer workspace/profile path, and runs safe automations with approval gates for risky actions. Current focus: ecommerce/operator onboarding, context compilation, dashboard, tickets, and future NemoClaw sandbox isolation.
