Tendr Skill Adds CLI-Based Long-Term Memory with Hierarchy to Reduce Token Usage

A new skill for OpenClaw addresses inefficiencies in long-term memory management by separating reasoning from execution. Instead of having the agent perform file operations directly, the agent decides what needs to change and a CLI tool handles the structural operations deterministically.
Key Features
- Reduced Token Usage: The skill cuts down on token consumption by moving file operations to a CLI tool. For example, renaming a concept across fifty files requires just one command with zero tokens used by the agent.
- Deterministic Operations: The CLI tool handles structural operations deterministically, preventing errors from compounding over sessions.
- Wikilinks Support: The system supports [[wikilinks]], allowing the agent to understand how concepts relate to other concepts.
- Semantic Hierarchy: It supports an explicit semantic hierarchy across files, giving the agent awareness of intended abstractions and generalizability rather than just knowing a concept exists.
Problem Addressed
The skill addresses the common pattern where OpenClaw memory setups have the agent performing its own file surgery—reading, parsing, and rewriting markdown files. This approach burns tokens and allows errors to compound over multiple sessions.
This type of tool is useful for developers working with AI coding agents who need persistent, structured memory systems that maintain consistency without consuming excessive tokens on file operations.
