Check Health

check-health

Homeostasis monitor. Collects hardware metrics (GPU, CPU, RAM, disk, network, processes) via system-health.sh and cognitive metrics (memory integrity, tool effectiveness, world model health, planning performance) from internal state. Returns a structured health report.

Input

No required input. Runs all checks automatically.

Output

Success (status: "success"):

• value: Human-readable summary string — lists concerns if any, otherwise "All systems nominal."
• The bound Note ($health) contains a JSON object with these top-level keys:
  • overall_status: "ok" | "warning" | "critical"
  • concerns: list of human-readable concern strings (empty if all ok)
  • system: hardware/OS metrics (cpu, gpu, ram, disk, network, processes)
  • cognitive: cognitive metrics (memory, planning, tool_model, world_model, user_interaction)

Reading the health report in code blocks

health = executor.get_json("$health")
overall = health["overall_status"]       # "ok", "warning", or "critical"
concerns = health["concerns"]            # e.g. ["Plan completion rate low: 45% (last 20 plans)"]

Do NOT use health.get("extra", {}).get("overall_status") — overall_status and concerns are at the top level of the Note content, not nested under extra.

Behavior

• Calls src/scripts/system-health.sh synchronously to collect OS/hardware metrics
• Reads cognitive state from executor, resource_manager, tool_model, and world_model
• Classifies each signal as ok / warning / critical based on thresholds
• Does NOT communicate with the user — returns data for the planner to act on

Common Workflows

Scheduled health check (planner decides what to report):

{"type":"check-health","out":"$health"}

The planner reads $health via executor.get_json("$health") and decides whether to say or ask the user based on overall_status and concerns.
