BB nex-healthcheck
Multi-service health and uptime monitoring dashboard for websites, APIs, infrastructure, and applications across multiple systems. Monitor website availability and HTTP response codes with configurable status code validation, check SSL certificate expiration dates with advance warnings (30-day warning, 7-day critical threshold), verify DNS resolution and nameserver health for domain infrastructure. Monitor Docker container status and container-level health checks, track systemd service status on both local and remote machines via SSH, and perform network connectivity tests (TCP port connectivity, ICMP ping, SSH command execution with response validation). Configure flexible health checks including HTTP/HTTPS endpoint monitoring with custom ports, TCP port connectivity without HTTP, DNS resolution verification against multiple record types (A, AAAA, MX, NS), and complex remote checks through SSH including systemctl status queries and docker ps commands on remote infrastructure. Optional Telegram notifications alert you immediately when services degrade or certificates approach expiration with contextual information. View historical incident data with start/end times and duration, uptime percentages for specific date ranges, and SLA tracking for compliance reporting and incident analysis. Designed for DevOps engineers, system administrators, agency operators, and IT teams managing multiple production systems and critical services.

What is at stake
Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The skill contains commands that delete files, rewrite disks or execute code fetched from the network. The agent may run them without asking if it believes the instructions require it.
Replace destructive commands with safe equivalents that ask for confirmation, scope them to one folder, and stop piping curl into a shell: pin a version and a checksum.
How to improve
- Shorten the description to 1024 characters.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 71/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 100Steps. 35 steps
- 100Failures and branches. 1 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1735 tokens
- 100Running it twice. Mutating operations check current state
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
