Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

How to run (transparent)

Take the absolute Base directory for this skill from the Skill tool

(the folder that contains this skill's SKILL.md and run.mjs).

Set SKILL_BASE to that path. Do not invent versioned cache paths.
Always invoke the companion only through this skill's runner:

SKILL_BASE=''
node "$SKILL_BASE/run.mjs"  [args...]

run.mjs finds the plugin install from its own location and runs scripts/grok-companion.mjs. No CLAUDE_PLUGIN_ROOT / PLUGIN_ROOT required.

If the host already exported CLAUDE_PLUGIN_ROOT or PLUGIN_ROOT, you may call node "$CLAUDE_PLUGIN_ROOT/scripts/grok-companion.mjs" instead; prefer "$SKILL_BASE/run.mjs" whenever the Skill tool loaded this skill.

Return companion stdout verbatim. Never put free-text in --task "..."; use --task-file - with a single-quoted heredoc.

Command

node "$SKILL_BASE/run.mjs" preflight

Return the JSON readiness envelope verbatim. Preserve exit status.
