在 OpenClaw 中安装
/install signl4
功能描述
Send and close SIGNL4 alerts using the SIGNL4 inbound webhook (team secret in URL).
安全使用建议
This skill appears to do only what it says: POST JSON to the SIGNL4 inbound webhook using the team secret in the URL. Before installing, ensure you: (1) only provide a team secret intended for webhook use (rotate it if exposed), (2) do not embed the secret in chat messages or logs (the SKILL.md already warns against printing it), and (3) trust the agent to send/resolve alerts on your behalf because autonomous invocation would allow it to issue webhook calls without manual approval. If you need stricter control, keep the secret scoped/rotated and require manual confirmation before sending alerts.
功能分析
Type: OpenClaw Skill
Name: signl4
Version: 1.0.0
The skill is designed to interact with the SIGNL4 alerting system via its inbound webhook. It uses `curl` to send and close alerts, authenticating with a `SIGNL4_TEAM_SECRET` environment variable. All commands and instructions for the agent are directly aligned with this stated purpose, targeting the legitimate `connect.signl4.com` domain. The `SKILL.md` explicitly includes security notes instructing the agent not to print or echo the team secret, which is a positive indicator of responsible design. No evidence of data exfiltration, malicious execution, persistence, prompt injection with harmful intent, or obfuscation was found across `_meta.json`, `SKILL.md`, and `README.md`.
能力评估
Purpose & Capability
Name/description match the required binaries and env var (curl and SIGNL4_TEAM_SECRET). Requested resources are appropriate for calling an inbound webhook.
Instruction Scope
SKILL.md only instructs the agent to build the webhook URL from SIGNL4_TEAM_SECRET and POST alert or resolve payloads to the documented SIGNL4 endpoint; it does not ask to read system files or unrelated environment variables.
Install Mechanism
Instruction-only skill with no install spec or downloaded code; nothing is written to disk or installed by the skill itself.
Credentials
Only a single credential (SIGNL4_TEAM_SECRET) is required and declared as the primary credential. Optional SIGNL4_WEBHOOK_BASE is reasonable. No unrelated secrets or config paths are requested.
Persistence & Privilege
Skill is not marked always:true and does not request persistent system-wide changes. Default autonomous invocation is allowed (platform normal) but not combined with other privilege concerns.
