How do I install the Edgehdf5 Memory skill?

Run npx skillmds@latest add modbender/edgehdf5-memory in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Edgehdf5 Memory safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. Capability flags: executes scripts. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Edgehdf5 Memory?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Edgehdf5 Memory free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Edgehdf5 Memory

HDF5-backed persistent cognitive memory for AI agents. Use when: (1) saving conversation exchanges to long-term memory, (2) searching/recalling past conversations by semantic similarity, (3) managing agent memory files — stats, export, snapshot, WAL flush, (4) generating AGENTS.md summaries from memory. Requires the `edgehdf5` CLI binary (install via `cargo install edgehdf5-cli`).

File contents

EdgeHDF5 Memory

Persistent HDF5-backed memory with vector search, BM25 hybrid retrieval, Hebbian learning, and temporal decay.

Setup

# Install the CLI (one-time)
cargo install edgehdf5-cli
# Or from source:
cargo install --path crates/edgehdf5-cli

Set EDGEHDF5_PATH env var or pass --path <file.h5> to every command.

Commands

All output is JSON for easy parsing.

Create a memory file

edgehdf5 --path agent.h5 create --agent-id myagent --dim 384 --wal

Save an entry

Pass JSON via --json or stdin:

edgehdf5 --path agent.h5 save --json '{"chunk":"User asked about weather","embedding":[0.1,0.2,...],"source_channel":"discord","timestamp":1700000000.0,"session_id":"s1","tags":"weather"}'

Embedding must match the dimension specified at creation.

Search memory

edgehdf5 --path agent.h5 search --embedding '[0.1,0.2,...]' --query 'weather forecast' -k 5

Optional: --vector-weight 0.7 --keyword-weight 0.3 (defaults).

Recall a specific entry

edgehdf5 --path agent.h5 recall 42

Stats

edgehdf5 --path agent.h5 stats

Returns: count, active entries, WAL pending, config details.

Flush WAL

edgehdf5 --path agent.h5 flush-wal

Generate AGENTS.md

edgehdf5 --path agent.h5 agents-md
# Or write to file:
edgehdf5 --path agent.h5 agents-md --output AGENTS.md

Export all entries

edgehdf5 --path agent.h5 export

Outputs one JSON object per line (JSONL).

Snapshot

edgehdf5 --path agent.h5 snapshot backup.h5

Workflow: Saving Conversations

After each exchange, construct a MemoryEntry JSON with the conversation chunk and its embedding vector
Pipe to edgehdf5 save
The WAL (if enabled) ensures low-latency writes — flush periodically with flush-wal

Workflow: Recalling Context

Embed the current query using your embedding model
Run edgehdf5 search --embedding '[...]' --query 'user text' -k 10
Use returned chunks as context for the response

Notes

Embeddings must be generated externally (e.g., via an embedding API or local model)
The .h5 file is a standard HDF5 file readable by any HDF5 library
WAL files are stored alongside the .h5 file as <name>.h5.wal
