Open Source · Built in Go

An AI-native development toolchain — and a decade of Go before it.

Small, sharp tools focused on one problem: making LLM-driven development reliable enough for production. Specs as contracts, deterministic reviews, context budgets, test gaps — the unglamorous plumbing that turns an AI agent from a demo into something you'd actually ship with.

The agentic coding toolkit.

Ten tools that compose into a complete spec-first workflow for AI-assisted development: specify, plan, build, review, verify, document.
speccritic
Active

Evaluates software specifications as formal contracts. Identifies contradictions, hidden assumptions, and missing prerequisites before a line of code is written.

plancritic
Active

Reviews implementation plans and returns structured critique: contradictions, ambiguities, missing prerequisites, and concrete patches. The check step between spec and code.

View repo
prism
Active

Local-first AI code review CLI. Reviews git diffs, commits, ranges, and PRs using Anthropic, OpenAI, Gemini, or Ollama. Emits text, JSON, SARIF, and Markdown — with CI-friendly exit codes and pre-commit hooks.

GoReviewMulti-LLM

View repo
realitycheck
Active

Intent enforcement for agentic coding systems. Verifies that code matches SPEC.md and PLAN.md — and only that. Catches the drift between what was asked for and what the agent actually built.

clarion
Active

Evidence-backed documentation for Go repos. Scans code, builds a Fact Model, then generates architecture / API / data-model / runbook docs via LLM — every claim traceable back to source.

verifier
Active

Spec-driven test-strategy analysis. Reads your specs, plans, and Go code to find the tests you don't have — and scaffolds honest skeletons for the ones that matter.

atlas
Active

Builds a structural and semantic index of a source repository in SQLite — designed to give AI coding agents a grounded view of the codebase instead of raw text.

specBuilder
Active

Requirements compiler: transforms product ideas into formal, machine-usable specifications for AI coding agents. Uses LLMs as constrained compilers with strict structured outputs — not chatbots.

aperture
Active

Deterministic context planner for coding agents. Scores, budgets, and explains which files to load before the agent runs — so LLM context becomes a designed artifact, not a guess.

witness
Active

Terminal-first observability for AI-driven development workflows. The missing "what did the agent actually do?" layer — designed for the command line, not a dashboard.

Adjacent work — agents, data, and the healthcare stack.

LLM infrastructure, graph tooling, and the HL7 / FHIR libraries from a decade of healthcare IT. Smaller scope than the flagship suite, still worth depending on.

Autonomous AI agent framework — reliable, observable, tool-using agents with safety controls and deterministic testing.

GoAgents
lattice

Graph-based work tracking. Three states, free-form tags, first-class relationships between work items.

GoGraph
langgraph-go

Go-native orchestration for stateful, graph-based LLM workflows. Typed state, deterministic replay, checkpointing, and multi-provider adapters.

GoLLM
EmbeddixDB

High-performance vector database in Go, built around LLM memory use cases.

GoVector DB
golevel7v2

HL7 v2.x parser, encoder, and MLLP network library. Streaming parser, struct marshaling, rule-based validation, ACK/NAK generation.

GoHealthcare
golevel7

The original HL7 v2.x decoder/encoder in Go. Widely used across healthcare-IT integrations since 2022.

GoHL7
gofhir
