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_BASEto that path. Do not invent versioned cache paths. - Always invoke the companion only through this skill's runner:
SKILL_BASE=''
# Required for completion notifications (plugin/references/execution-context.md):
export GROK_COMPANION_EXECUTION_CONTEXT=foreground # or background
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 "$SKILL_BASE/run.mjs" whenever the Skill tool loaded this skill.
Return companion stdout verbatim. Never put free-text in --task "..."; use --task-file - with a single-quoted heredoc.
Command
Never --task "...". Example:
export GROK_COMPANION_EXECUTION_CONTEXT=foreground
node "$SKILL_BASE/run.mjs" adversarial-review [flags from $ARGUMENTS, values single-quoted] --task-file -
GROK_TASK
Return the envelope verbatim.
