Abhiuday — Systems & AI Engineer. Documenting the build, one commit at a time.
Architecting autonomous agent runtimes, deterministic DAG workflow engines, and low-latency sandboxing infrastructure. Documenting internal design decisions and production post-mortems.
Featured Systems & Runtimes
agent-brain
v0.9.4-rcAutonomous hierarchical planning and memory runtime for multi-agent swarms with local MCP vector routing under token budget. Tokio channels, dynamic validation, and zero-copy gRPC serialization.
dustmap
Blazing-fast macOS disk space visualizer and conservative system cleaner in Rust & Tauri.
agentrun
↗Isolated, recoverable coding agent runtimes with container sandboxing and strict eBPF syscall filtering (4ms boot).
agent-spine
↗Deterministic multi-step DAG workflow runner with approval gates, state machine orchestration, and deterministic replay.
Recent Engineering Dispatches
agent-brain: the architectural pivot — from passive retrieval to deterministic cognitive runtime
Part 3 of the agent-brain series: why passive context retrieval broke down in real-world autonomous coding, how we pivoted into a hard-gated execution runtime with token budgets, verify invariants, and upstream MCP routing.
agent-brain: memory scopes, temporal pruning, and cross-session routing
Part 2 of the agent-brain series: how we evolved local MCP routing with global vs project memory scopes, temporal fact decay, cross-session ingest, and circuit-broken upstream tools.
AgentRun: Building Isolated, Verifiable Coding Agent Environments
The architecture and ongoing implementation of AgentRun: sandboxing coding agents with Apple containers, git worktree isolation, append-only decision logging, and bounded repair loops.
Building DustMap: A Blazing-Fast, Transparent macOS Disk Analyzer in Rust and Tauri
Why I built DustMap: parallel Rayon filesystem traversal, flat memory indexes with zero pointer chasing, APFS dual-metric reconciliation, and an explainable Trash-first cleaner.
agent-brain: local MCP routing under a token budget
How I built a Rust MCP server that routes each agent turn to the right skills, rules, and memory — locally, with hook-enforced route_task and strict token limits.
