ATXP Memory — Agent Memory Management

Manage your agent's .md memory files: back up and restore to/from ATXP cloud servers, and search your local memories using zvec vector similarity search.

Capabilities

Capability	Description
Cloud Backup	Push/pull .md files to ATXP servers for disaster recovery
Local Search	Index .md files into a local zvec vector database, then search by natural language query
Status	View cloud backup info and local index statistics

Security Model

• Only .md files are collected and transmitted (push/pull). No credentials, JSON configs, binaries, or other file types are ever sent.
• Files are sent to ATXP servers over HTTPS, associated with the authenticated agent's identity.
• push replaces the server snapshot entirely (latest snapshot only, no history).
• pull is non-destructive — it writes server files to the local directory but does not delete local files absent from the server.
• Local search index is stored in a .atxp-memory-index/ subdirectory inside --path. It never leaves the local machine.
• index and search do not require authentication or network access.
• Filesystem access: reads from --path directory (push/index), writes to --path directory (pull) and --path/.atxp-memory-index/ (index). No other directories are touched.
• No modification of OpenClaw config or auth files.

When to Use

Situation	Command
After meaningful changes to SOUL.md, MEMORY.md, or at end of session	push
Bootstrapping a fresh workspace or recovering from environment loss	pull
After updating memory files and before starting a task that requires recall	index
Looking for relevant context in past memories	search
Verify backup exists before risky operations	status

Commands Reference

Command	Description
npx atxp@latest memory push --path <dir>	Recursively collect all *.md files from <dir> and upload to server
npx atxp@latest memory pull --path <dir>	Download backup from server and write files to <dir>
npx atxp@latest memory index --path <dir>	Chunk .md files by heading and build a local zvec search index
npx atxp@latest memory search <query> --path <dir>	Search indexed memories by similarity
npx atxp@latest memory status [--path <dir>]	Show cloud backup info and/or local index stats

Options

Option	Required	Description
--path <dir>	Yes (push/pull/index/search)	Directory to operate on
--topk <n>	No (search only)	Number of results to return (default: 10)

How Local Search Works

1. Indexing (memory index):

   • Scans all .md files recursively from --path
   • Splits each file into chunks at heading boundaries (h1/h2/h3)
   • Converts each chunk into a 256-dimensional feature vector using locality-sensitive hashing (unigrams + bigrams)
   • Stores vectors and metadata in a local zvec database (HNSW index) at <path>/.atxp-memory-index/

2. Searching (memory search):

   • Converts the query text into the same vector representation
   • Performs approximate nearest neighbor search via zvec's HNSW index
   • Returns the top-k most similar chunks with file paths, headings, line numbers, and similarity scores

The search is purely local — no network requests, no API keys, no cost. Re-index after modifying memory files.

Path Conventions

Typical OpenClaw workspace paths:

~/.openclaw/workspace-<id>/
~/.openclaw/workspace-<id>/SOUL.md
~/.openclaw/workspace-<id>/MEMORY.md
~/.openclaw/workspace-<id>/memory/
~/.openclaw/workspace-<id>/AGENTS.md
~/.openclaw/workspace-<id>/USER.md

Backward Compatibility

The backup command is still accepted as an alias for memory:

npx atxp@latest backup push --path <dir>   # works, same as memory push
npx atxp@latest backup pull --path <dir>   # works, same as memory pull
npx atxp@latest backup status              # works, same as memory status

Limitations

• .md files only — all other file types are ignored during push/index and not present in pull.
• Latest snapshot only — each push overwrites the previous backup. There is no version history.
• Requires ATXP auth for cloud operations — run npx atxp@latest login or npx atxp@latest agent register first.
• --path is required — there is no auto-detection of workspace location.
• Local search requires @zvec/zvec — install with npm install @zvec/zvec before using index/search.
• Feature-hash embeddings — local search uses statistical text hashing, not neural embeddings. It works well for keyword and phrase matching but is not a full semantic search. For best results, use specific terms from your memory files.
