toolfs
Unified virtual filesystem framework for LLM agents. Provides access to files, memory, RAG, skills, and snapshots through a single interface. Use this skill when the user requests file operations, memory storage, semantic search, skill execution, or state management tasks.
npx skills add majiayu000/claude-skill-registry --skill skills-icewhaletech-toolfs --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# ToolFS ToolFS is a unified virtual filesystem framework for LLM agents that provides access to files, memory, RAG systems, skills, and snapshots through a single `/toolfs` namespace. ## Overview ToolFS integrates multiple data sources and operations into one virtual filesystem: - **Memory**: Persistent key-value storage for session data and context - **RAG**: Semantic search over vector databases for document retrieval - **Filesystem**: Access to mounted local directories - **Skills**: Execute WASM-based skills mounted to virtual paths - **Snapshots**: Create point-in-time snapshots and restore previous states All operations respect session isolation, permission control, and audit logging for safe execution in sandboxed environments. ## Available Skills ToolFS is organized into functional modules. Each module provides specific capabilities: | Module | Path | Description | Documentation | |--------|------|-------------|---------------| | **Memory** | `/toolfs/memory` | Persistent storage for session data and context | [Memory Skill](memory/SKILL.md) | | **RAG** | `/toolfs/rag` | Semantic search over vector databases | [RAG Skill](rag/SKILL.md) | | **Filesystem** | `/toolfs/<mount>

What does the toolfs skill do?
Unified virtual filesystem framework for LLM agents. Provides access to files, memory, RAG, skills, and snapshots through a single interface. Use this skill when the user requests file operations, memory storage, semantic search, skill execution, or state management tasks.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill skills-icewhaletech-toolfs --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
