A self-contained editorial diagram library for docs and agent skills — 27 visual types, brand auto-matching, and no-JS static output for fast, consistent, and accessible diagrams.

Semantica is a graph-native infrastructure for regulated environments, delivering auditable decision objects, deterministic reasoning, and ontology governance to turn enterprise data into explainable, traceable context graphs for compliance and interpretability.

Needle 2 is an ultra‑compact model focused on tool calling and constrained decoding for structured extraction; a 14MB single file that enables offline edge inference and low‑resource deployment, though license and maintenance risks should be assessed.

Holehe is an OSINT tool that maps emails to registered accounts by probing password-recovery and login endpoints across 120+ services. It offers a CLI and asynchronous Python modules for integration, and is best applied in controlled, legally compliant workflows such as threat intelligence, red teaming, and privacy audits.

Prime Agent delivers a programmable, persistent RLM agent runtime for research and long‑running automation, enabling local execution of complex workflows while preserving session state.

Macro aims to be an all-in-one workspace for small teams, connecting email, messages, docs, tasks and CRM with shared team memory to reduce tool switching and improve collaboration; however, the public repository currently lacks active maintenance, releases and license information, so risk and compliance checks are required before adoption.

Code-Graph-RAG parses multi-language repositories with Tree-sitter into a unified Memgraph knowledge graph, enabling natural-language queries, Cypher retrieval, AST-level structural rewrites, and AI-assisted optimization—suited for teams needing large-scale code understanding, refactoring, and auditing.

Unsloth delivers a memory-friendly fine-tuning and RL toolchain for research and engineering, supporting multiple models and free notebooks—great for low-cost prototyping and experiments, but production readiness and performance reproduction require careful evaluation.

Manim, originated by 3Blue1Brown, is a programmatic math-animation engine that produces reproducible, high-precision instructional visuals; ideal for educators and creators with Python and CLI experience for math visualization and outreach.

Omarchy turns a fresh Arch install into an opinionated, Hyprland‑based web development desktop with a single command—ideal for Arch users who prefer preconfigured, quick‑onboarding environments.

Agent Skills packages senior-engineer workflows into reusable agent-invokable skills to improve consistency and engineering quality across development stages.

Modly is a desktop tool for local GPU inference that converts photos into exportable 3D meshes via extensible AI workflows, aimed at developers and artists needing self-hosted generation.

A layered memory system for long-horizon, multi-step agents that combines Mermaid-based symbolic short-term memory with hierarchical long-term representations to reduce context/token costs while preserving traceability and on-demand drill-down — intended for agent platforms that require persistent context management and auditability.

Anthropic/skills is a collection of skill specifications and examples for Claude, offering reusable templates and document-skill references suitable as a foundation for custom skill development; however, license clarity and community activity should be assessed before production adoption.
