developer tools

A hands-on workshop repository that walks developers through building a small GPT-style language model from scratch, including tokenization, transformer blocks, training, and text generation.

Hapsland is a developer tool that gives coding agents realtime semantic review on code changes, with privacy-aware request scoping and feedback loops back to the agent.

HDTP is a protocol specification for agent-to-agent communication on behalf of people, centered on certificates, contact approval, per-caller permissions, and sealed end-to-end calls.

A small open model trained to turn English requests into Bash commands, with published training data, GGUF weights, and benchmark results.

Graphene is a data analytics framework built for coding agents, with a CLI, SQL-based semantic models, and Markdown pages for dashboards and reporting.

ToolHub is a self-hosted open-source platform that turns scripts into AI tools and organizes them in a hierarchical tree for agents to browse and execute. The page shows architecture notes, execution flow, screenshots, and a live demo/web client reference.

Jev AI is an interactive playground and API for typed AI decisions, with yes/no, choice, and scoring outputs plus confidence signals for routing, moderation, and other workflow decisions.

A CLI and agent skill that checks whether tests actually exercise real behavior, with a TypeSafe API key flow, diff-based audits, and CI-friendly output.

A TypeScript CLI for AI-native development that scans a codebase, maps dependency graphs and blast radius, and helps AI tools make safer changes with architectural context.

A Claude Code plugin/repo that changes how instruction files are loaded, adding support for AGENTS.md alongside CLAUDE.md. The page explains the modes, configuration options, and hook behavior in enough detail to be useful for developers using Claude Code.

A local-first desktop AI agent with persistent memory, a browser-capable control UI, onboarding flow, and P2P skill sharing.

Ridge is a resource mesh for AI agents, with MCP, CLI, and Python access to local projects, Docker, SSH machines, and S3 storage. It focuses on delegated resource access, job coordination, and keeping artifacts out of model context.

Botbin is a pastebin-style publishing tool for AI agent artifacts. It lets agents upload single-file HTML outputs like dashboards, charts, and visual diffs and share them through clean URLs instead of raw HTML in chat.

A capability-based microkernel written in SPARK Ada and formally verified with gnatprove, with a thin C SDK for building services and distribution components.

React hooks for exposing app functionality as WebMCP tools, with Zod-based inputs, SSR-safe behavior, StrictMode safety, and a bridge to AI clients like Claude and Cursor.

A serverless reverse geocoding SDK and browser experience for web and embedded devices, with support shown for WebMCP and embedded targets like RP2040, RP2350, and ESP32.

Live demo of a prompt-injection defense for LLMs using per-position semantic overlays. The page shows how marked spans can be treated as untrusted while the base model stays frozen, with interactive examples for retrieved text, hidden instructions, language marking, and request-scoped overlays.

Keel is a Rust CLI harness for AI-assisted coding workflows. It adds auditable stopping conditions, durable memory, projections into agent instruction files, and reviewable gates with exported evidence.

A long-form technical guide on running local LLMs in the browser, with checks for WebGPU support, model hashes, tokenizer matching, and browser-side data leakage.

Windows desktop client for DeepSeek Harness that wraps the official web UI into a native app with installer, tray integration, built-in browser, and terminal support.

A professional network for coding agents where agents can have profiles, post shipped work, connect, and take jobs, with a public feed and human portal for claiming ownership.

Myli is a provider-neutral Python harness for multi-agent visual design workflows. It defines typed design specs, validates JSON candidates at runtime, supports tools and middleware, and can render candidates for visual review with event and trace reporting.

OpenAI API documentation page for the GPT-5.6 Sol model, with links into model selection, pricing, reasoning, prompting, and SDK guidance.

AgentSight is a zero-instrumentation observability tool for AI agents that uses eBPF to trace LLM API calls, token usage, and process behavior on Linux.
