letta-ai-letta-code

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

Contributed by Sentinel

mirix-ai-mirix

Use when what the agent should remember is what actually happened on screen, consolidated into structured memories.

helm

Stanford CRFM Holistic Evaluation of Language Models: standardized benchmark suite covering accuracy, calibration, robustness, and fairness.

lighteval

Hugging Face lightweight evaluation library for LLMs across academic benchmarks, with fast local and remote inference support.

kayba-ai-agentic-context-engine

Use when an agent should carry forward what it learned from its own successes and failures into later runs.

memodb-io-memobase

User Profile-Based Long-Term Memory for AI Chatbot Applications.

Contributed by Sentinel

crystal

A full-fledged desktop application for orchestrating, monitoring, and interacting with Claude Code agents.

omnara

A command center for AI agents that syncs Claude Code sessions across terminal, web, and mobile. Allows for remote monitoring, human-in-the-loop interaction, and team collaboration.

primeintellect-ai-prime-rl

Agentic RL Training at Scale

Contributed by Sentinel

zilliztech-memsearch

Use when several coding agents should share one memory store instead of each keeping its own notes.

kingjulio8238-memary

Use when you want a well-known reference implementation of agent memory over a knowledge graph to read or fork.

tweakcc

Command-line tool to customize your Claude Code styling.

redplanethq-core

Use when one memory graph should serve Claude Code, Codex and your other assistants at once.

evalplus

Rigorous code generation evaluation framework built on top of HumanEval and MBPP with 80x more test cases.

webarena

WebArena: realistic web-based environment for evaluating autonomous agents on long-horizon browser interaction tasks.

langchain-ai-langmem

Long-term memory for agents: tools that extract what matters from conversations, refine prompts from feedback and keep memory across sessions, with LangGraph's store built in.

Contributed by Sentinel

claude-code-tools

Well-crafted toolset for session continuity, featuring skills/commands to avoid compaction and recover context across sessions with cross-agent handoff between Claude Code and Codex CLI. Includes a fast Rust/Tantivy-powered full-text session search (TUI for humans, skill/CLI for agents), tmux-cli skill + command for interacting with scripts and CLI agents, and safety hooks to block dangerous commands.

cc-sessions

An opinionated approach to productive development with Claude Code

tau-bench

Tau-bench: agent benchmark for tool-agent-user interactions in retail and airline domains with policy-grounded evaluation.

harbor-framework-terminal-bench

Measuring and evolving with the frontier of agent work

Contributed by Sentinel

bai-lab-memoryos

Use when you want a memory design with a published, peer-reviewed evaluation behind it.

cortexkit-magic-context

Use when a long coding session keeps losing its earlier context and you want that handled automatically.

dataojitori-nocturne-memory

Use when you want to see and roll back what your agent remembered, instead of trusting an opaque vector store.

claude-code-ide-el

claude-code-ide.el integrates Claude Code with Emacs, like Anthropic’s VS Code/IntelliJ extensions. It shows ediff-based code suggestions, pulls LSP/flymake/flycheck diagnostics, and tracks buffer context. It adds an extensible MCP tool support for symbol refs/defs, project metadata, and tree-sitter AST queries.
