Description
Send Live-Activities & Ongoing-Notifications to your iOS / Android phones using Signalgrid.
Usage Guidance
This skill appears to be what it claims: a small Node script that POSTs multipart form data to api.signalgrid.co using SIGNALGRID_CLIENT_KEY and SIGNALGRID_CHANNEL. Before installing or using it, consider the following:
- Fix the two clear bugs in signalgrid-activity.js before relying on it in production: change the token variable to read args.token (update_token = args.token || "") so update/end flows work as documented, and define isCritical (e.g., const isCritical = finalType === 'crit') or remove it to avoid a ReferenceError that causes the script to exit non-zero even after a successful request.
- Test start/update/end flows locally after setting SIGNALGRID_CLIENT_KEY and SIGNALGRID_CHANNEL to confirm token propagation and correct exit behavior.
- Keep SIGNALGRID_CLIENT_KEY secret — treat it like any API key. Confirm the key's scope/permissions with Signalgrid and rotate/revoke if compromised.
- The skill posts to api.signalgrid.co; if you require stricter network controls, vet that domain and the Signalgrid service first.
- Because the skill runs arbitrary Node code, only install from sources you trust; the current package is small and contains no obfuscated or external downloads, but always review updates for changes.
If you want, I can produce a patched version of signalgrid-activity.js with the token and isCritical fixes and optional improvements (better exit codes, response handling, and safer logging).
Capability Analysis
Type: OpenClaw Skill
Name: signalgrid-activity
Version: 1.0.16
The skill is a legitimate tool for sending mobile notifications via the Signalgrid API (api.signalgrid.co). The Node.js script (signalgrid-activity.js) correctly handles environment variables for authentication and constructs a multipart/form-data request to the service provider. While the script contains a minor bug (a ReferenceError due to an undefined 'isCritical' variable in the final log statement), there is no evidence of malicious intent, data exfiltration, or unauthorized command execution.
Capability Assessment
Purpose & Capability
Name/description, required binaries (node), and required env vars (SIGNALGRID_CLIENT_KEY, SIGNALGRID_CHANNEL) align with a notification-sending skill. The package and API host (api.signalgrid.co) are consistent with the described service.
Instruction Scope
SKILL.md instructs running the included node script with parameters (including --token). The bundled script largely implements that behavior, but it contains bugs that break intended behavior: (1) the script reads args.update_token rather than args.token, so a provided --token won't be transmitted; (2) console.log references an undefined variable (isCritical), which will throw and cause the process to exit with error after the request completes. These are functional/incoherence issues in the runtime instructions vs. implementation.
Install Mechanism
No install spec (instruction-only install via clawdhub). The skill contains a small Node script and package.json; there are no external downloads or obscure URLs. No extract or remote code fetch during install.
Credentials
Only two service-specific env vars are required (client key and channel). These are appropriate and proportional for a notification API integration. The script only reads those two env vars.
Persistence & Privilege
always:false and no install-time changes are requested. The skill does not request persistent system privileges or modify other skills/configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install signalgrid-activity - After installation, invoke the skill by name or use
/signalgrid-activity - Provide required inputs per the skill's parameter spec and get structured output
