Persistent agent memory for OpenClaw. Surface past failures, log decisions, and compound intelligence across sessions. Use when an agent should enforce Marro...
Usage Guidance
This skill appears to do what it says (agent memory) but it mandates frequent logging to an external service and leaves redaction up to the agent. Before installing: 1) Confirm you trust getmarrow.ai and review their privacy, retention, and access policies; 2) Limit the MARROW_API_KEY scope where possible and use short-lived or revocable credentials; 3) Avoid enabling this skill in environments that handle sensitive PII, secrets, or regulated data unless you have contractual/data-residency guarantees; 4) Test in a sandbox with non-sensitive operations to verify what gets logged; 5) Consider monitoring outbound network calls and auditing logged memories on the Marrow side; 6) If you cannot guarantee safe redaction or vendor controls, do not enable mandatory automatic logging.
Capability Analysis
Type: OpenClaw Skill
Name: marrow
Version: 1.0.0
The skill provides instructions and a reference for using the Marrow MCP server to maintain persistent agent memory. It includes explicit safety guidelines in SKILL.md that forbid the logging of secrets, API keys, and PII, and it aligns perfectly with its stated purpose of improving agent decision-making through historical context. No malicious code, obfuscation, or unauthorized data exfiltration patterns were found.
Capability Assessment
Purpose & Capability
Name/description and required credential (MARROW_API_KEY) align: a persistent memory service legitimately needs an API key. No unrelated binaries, config paths, or extra credentials are requested.
Instruction Scope
SKILL.md forces the agent to call Marrow before/after every 'meaningful' action and to make other lifecycle calls. While redaction rules are documented, logging is mandatory and the instructions give the agent broad discretion about what to log. Because the skill is instruction-only, redaction/enforcement depends entirely on correct agent behavior — increasing risk of accidental leakage of sensitive context (files, API payloads, config, etc.).
Install Mechanism
No install spec or downloaded code is present (instruction-only). This minimizes filesystem/remote-install risk.
Credentials
Only MARROW_API_KEY is required, which is proportionate to the service. However, that single key likely grants the external Marrow service read/write access to all logged memories; combined with mandatory, frequent logging this can surface broad contextual data even though only one env var is requested.
Persistence & Privilege
always is false and the skill does not request system-wide configuration or other skills' credentials. Autonomous invocation is allowed (platform default) but not escalated by this skill.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install marrow - After installation, invoke the skill by name or use
/marrow - Provide required inputs per the skill's parameter spec and get structured output
