Usage Guidance
This skill appears to do what it says, but before installing: (1) confirm the agent's 'message' and transcription tools are trusted and won’t send data to unexpected external endpoints; (2) be aware wa-relay-log.md will store third-party messages — decide on retention, encryption, or deletion policies; (3) ensure SOUL.md/USER.md are the right place for your owner number and that the skill only reads the minimum required fields; (4) test in a safe environment to verify the 'NO_REPLY' behavior is implemented as intended and does not inadvertently leak context. If you need stronger privacy, require the skill to encrypt logs or restrict where logs are stored.
Capability Analysis
Type: OpenClaw Skill
Name: wa-relay
Version: 0.1.0
The wa-relay skill acts as a protective firewall for WhatsApp-enabled agents, specifically designed to prevent unauthorized third parties from interacting with or triggering the agent. The instructions in SKILL.md explicitly forbid executing commands from third parties or leaking owner context, and the logic focuses on relaying messages to a designated owner for approval, which aligns with its stated security purpose.
Capability Assessment
Purpose & Capability
Name/description match the instructions: the skill mediates WhatsApp inbound/outbound messages, logs conversations, and requires the owner's WhatsApp number in agent config. No unrelated credentials, binaries, or installs are requested.
Instruction Scope
SKILL.md instructs the agent to notify the owner via a 'message' tool and to transcribe audio (whisper or built-in). It also instructs reading SOUL.md/USER.md for owner number and maintaining memory/wa-relay-log.md. These file and tool accesses are expected for a relay but are important runtime surface area to be aware of (reads/writes agent memory/config and uses external messaging/transcription tools).
Install Mechanism
Instruction-only; no install spec, no downloads, no code files — lowest risk from install mechanism.
Credentials
The skill does not request environment variables or credentials, but it requires access to agent config files (SOUL.md/USER.md) and write access to memory/wa-relay-log.md. This is proportionate to logging and owner-identification, but the log will store third-party message content so consider privacy/retention controls.
Persistence & Privilege
always is false and the skill does not request elevated persistent privileges or to modify other skills. Autonomous invocation is allowed (platform default) but not combined with other concerning factors.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install wa-relay - After installation, invoke the skill by name or use
/wa-relay - Provide required inputs per the skill's parameter spec and get structured output
