Top COD GitHub Repositories & Tools (2026)

A control plane with a durable state kernel for long-horizon agents and teams. Keep work moving and improving across sessions, with less human attention.

Codebase intelligence for TypeScript and JavaScript. Free static analysis of code and styles: unused code, duplication, circular deps, complexity hotspots, architecture boundaries, design-system drift. Optional paid runtime layer (Fallow Runtime): hot-path review and cold-path deletion evidence from real production traffic.

Stateful agents that are like people, with memory, identity, and the ability to learn and adapt

Open source voice AI platform. Self-hosted alternative to Vapi and Retell. On Prem, BYOK across Speech to Speech or LLM/STT/TTS, with a visual workflow builder, MCP native and telephony support.

Art and animation, written as code. Illustrations, loops, interactive web art, launch-videos and scored films in dozens of styles, identical on every render.

Code as configuration. Annotate a Java entity with @Erupt and ship a production-grade admin backend in minutes — UI, RBAC, audit logs and APIs, all generated at runtime. No codegen, no frontend.

Local-first research memory for Codex: checkpoints, progress ledgers, and Markdown/JSON paper notes. Early alpha.

List of agent orchestrators

Generation of diagrams like flowcharts or sequence diagrams from text in a similar manner as markdown

Skill that audits and rewrites content to remove AI writing patterns. Use it with your favorite agents including Claude Code, OpenClaw, Codex, and Hermes.

Coding articles to level up your development skills

An extremely fast Python linter and code formatter, written in Rust.

Open Reality: phone video to AI-queryable 3D scenes. MCP tools for Claude/Codex/Cursor (npm openreality-mcp), the self-hostable broker, and the VGGT-SLAM library, in one repo. BSD-2-Clause.

All parts of Claude Code's system prompt, 27 builtin tool descriptions, sub agent prompts (Plan/Explore/Task), utility prompts (CLAUDE.md, compact, statusline, magic docs, WebFetch, Bash cmd, security review, agent creation). Updated for each Claude Code version.

Stop letting AI code blind. Map the architecture before every change with Birdview.

Typed decisions with TypeSafe's Jev, the first System One model

Static analysis for the debt AI agents leave in PHP: 25 rules, Claude Code hooks, git-diff review, a Rector and Pint fix pass, Pest expectations, CI annotations and an MCP server. Deterministic, local, no LLM.

Claude Code multi-account manager, usage monitor (CLI, TUI & MCP cross-account delegation)

An agent organization structured as a company — 15+ departments, 125+ skills, each independently installable, citing the standards and regulators that settle the question. Runs in Claude Code and ChatGPT.
