-### PrepForge · Python, FastAPI, React, SQLite
+### harnesskit — agent orchestration framework · TypeScript
+
+An open-source framework extracting production agent patterns into reusable modules. Tool registry with Zod schemas and permission levels. Query loop (input → context → model call → tool calls → repeat). Permission engine with deny/ask/allow cascade. Context manager with cache-aware compaction. Agent spawner with worktree isolation. Hook system with lifecycle events. Model router with tiered selection and fallback.
+
+The core idea: three intelligence levels — rule-based (no model, $0), hybrid (local model), and full agent (cloud model) — all running on the same architecture. The model is optional. The harness isn't.

+
+### Helix — personal knowledge system · Markdown, Git, Python
+
+The memory layer behind Jishu. A git repo of markdown files organized into four layers: immutable raw sources (work context, memories, plans, investigations), active state (goals, decisions, journal, feedback), personal context (rhythms, aspirations, relationships), and cognitive architecture (how Jishu thinks). Replaced a vector database (Milvus + Ollama embeddings) — prompt caching made flat file reads cheaper and more reliable than embed-retrieve-inject. [Wrote about the full design](/posts/giving-an-ai-agent-memory-that-survives-the-session).

-An interview preparation system I'm building for myself. Three thousand DSA problems sourced from LeetCode with company-wise tagging, twenty-six system design scenarios, twenty object-oriented design problems. Uses FSRS (Free Spaced Repetition Scheduler) to surface problems based on when I'm most likely to forget them. AI-powered coaching for hints and explanations, mock interview simulation.
+### Jira Ticket Creator · JavaScript, VS Code Extension API, Copilot LM API
 
-Still a work in progress — building it because I couldn't find a prep tool that combined spaced repetition with the specific problem sets I wanted.
+A zero-dependency VS Code extension for creating Jira tickets with AI assistance. Describe what you need, the extension generates summary, description, type, priority, and labels. Single and bulk ticket creation. Supports cookie auth for enterprise Jira behind SSO/IAP — built specifically to work with Motorola's Google Cloud IAP setup. Distributed to the team via GitHub Releases.
