Usage Guidance
This skill does what it says (local WAL + working buffer) and contains no network exfiltration or secret-env requirements, but it will persist specifics from user messages to files in your workspace by default. Before installing: (1) decide whether you want automatic capture enabled and, if not, disable auto_capture in memory-stack-config.json; (2) ensure the memory/ directory is excluded from backups and version control (add to .gitignore) and set restrictive file permissions; (3) lower max_entries / max_size_mb or enable rotation to limit retained data; (4) test in an isolated workspace first to confirm behavior; (5) avoid pasting secrets (API keys, passwords) into chats that will be captured, or add filtering rules. If you need stricter guarantees (encryption, secure storage, remote retention policies), consider hardening or rejecting this skill until those controls exist.
Capability Analysis
Type: OpenClaw Skill
Name: memory-stack-core
Version: 1.0.0
The skill implements a local memory management system (Write-Ahead Log and Working Buffer) to persist conversation state across sessions. The code in scripts/run.py performs standard file I/O within a dedicated 'memory/' directory and uses regex to extract relevant facts from messages, aligning perfectly with the documentation in SKILL.md. No network activity, suspicious execution patterns, or unauthorized file access were detected.
Capability Assessment
Purpose & Capability
Name/description match the delivered artifacts: SKILL.md describes a WAL, working buffer, daily logs and recovery; the included scripts/run.py implements file-backed WAL and buffer, reads a local config (memory-stack-config.json), and exposes the declared tool-like actions (wal_write, wal_read, buffer_write, buffer_read, memory_health, wal-auto). No unrelated binaries, env vars, or services are requested.
Instruction Scope
Instructions and script intentionally read and write files under the workspace/memory directory (wal.jsonl, working-buffer.md, daily logs). This is consistent with the purpose, but the automatic 'auto_capture' behavior scans every human message for paths, URLs, decisions, preferences, values, and corrections and appends matches to the WAL — meaning any sensitive specifics typed by users (passwords, API keys, tokens, paths, URLs) can be persisted to disk. That behavior is expected for this purpose but is a privacy/sensitive-data risk and should be configured/limited if needed.
Install Mechanism
No install spec is provided (instruction-only + included script). Nothing is downloaded or executed from external URLs; the included Python script is the only code. This is low-risk from an install mechanism perspective.
Credentials
The skill requests no environment variables, no external credentials, and no config paths outside the workspace. Its file I/O is limited to workspace/memory and a workspace config file — proportionate to the stated purpose.
Persistence & Privilege
always:false (no forced inclusion). The skill is invokable/autonomous by default (normal), and its core privilege is persistent local storage in the workspace. That persistence is necessary for the feature but increases the blast radius if the workspace is backed up, uploaded, or under version control. The skill does not modify other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install memory-stack-core - After installation, invoke the skill by name or use
/memory-stack-core - Provide required inputs per the skill's parameter spec and get structured output
