healthcheck

healthcheck is a skill for Claude Code, Codex from ssube/conclave. It costs 38 tokens per session (762 once invoked), scanned A, original, MIT.

A deterministic health check for Conclave services, meaning it checks service processes, web endpoints, databases, and available disk space without using an AI model.

In plain words
What is it for?
Checking PostgreSQL, Nginx, Synapse, ChromaDB, Ollama, Planka, terminal access, browser automation, and workspace disk usage in human-readable or JSON output.
Why use it?
It quickly shows whether the workspace is healthy, degraded, or in a critical state when monitoring or diagnosing infrastructure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

healthcheck scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (healthcheck.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
