Hitaji Bot — Autonomous Coding Agent

3 months1 developer

An autonomous coding agent that turns Slack requests into validated pull requests across 10+ microservices; 60+ generated pull requests have been merged.

The Challenge

A change that spans a multi-service architecture is mostly overhead: find the right services, understand their boundaries, wire up local environments in the right order, run the builds, then open the PRs. The thinking is a small fraction of the wall-clock time.

The Solution

I built a streaming agent with 20+ tools for code search, editing, git operations, parallel exploration, and service orchestration. It configures and starts dependent services, then runs builds, tests, and health checks before opening a pull request.

Key Features

Slack-driven task intake with autonomous code discovery across 10+ microservices

Streaming tool-calling loop with 20+ tools (ripgrep search, file editing, git operations)

Service orchestration: dynamic env configuration (dotenv + JSON), dependency-ordered startup, health checks

Workspace pooling with pre-warming (5 slots, max 8) and per-repo mutexes to prevent git contention

Two-phase build/test validation and a diff-analysis quality gate before any PR is published

Subagent spawning for parallel codebase exploration

Dual-provider LLM abstraction (Anthropic/OpenAI)

Impact & Results

60+ merged pull requests to date. Workspace pooling cut task startup latency by 40–60%.
