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

grok-cli-runtime scanned grade A with 0 findings 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 1mo ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

89% identical to grok-cli-runtime — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Grok Runtime

Use through the Grok MCP tools. If MCP is unavailable, call the companion directly with node plugins/grok/scripts/grok-companion.mjs <command> ....

Recommended Grok CLI version: ≥ 1.0.5 (minimum still 0.2.118; flags are capability-gated).

Workspace

Installed Codex plugin MCP servers start from the plugin cache. Pass cwd with the active project directory on every Grok MCP call so Grok inspects, edits, and stores artifacts in the intended workspace rather than the cached plugin directory. Direct companion calls can use --cwd <path>.

Concurrency

  • Multiple companion jobs may run at once. There is no global single-agent lock.
  • Prefer background: true or --background when a Codex turn is launching more than one Grok job.
  • Each MCP call should make exactly one companion invocation.
  • Parallelism = multiple background companion jobs, not a serialized queue.
  • When several jobs are running, always pass job ids to status / result / cancel.

Control flags (most write/plan commands)

MCP input keys map to companion flags:

MCP property Companion flag
sandbox --sandbox
planMode --plan
permissionMode --permission-mode
agent --agent
noSubagents --no-subagents
memory / noMemory --memory / --no-memory
allow / deny --allow / --deny (repeatable)
disableWebSearch --disable-web-search
forkSession --fork-session
maxTurns --max-turns

CLI posture

  • Prefer denylist (--disallowed-tools) over tools allowlist (Grok session-create bugs).
  • Media: no yolo / no tools allowlist.
  • --dry-run / --validate-only / babysit list: read-only (no yolo).
  • Write-capable default for rescue/design/execute/babysit add|check|remove.

Depth notes

  • grok_execute_plan with latest=true resolves newest .grok-designs/*.md.
  • Design/workflow/plan/document jobs harvest copies into .grok-designs/ / .grok-workflows/ / .grok-plans/ / .grok-docs/.
  • Review postPending=true: skips empty findings; empty/oversize diffs fail closed and save findings under .grok-reviews/.
  • Plan results prefer harvested plan.md body over narration.
  • Stop-gate uses sandbox read-only + denylist (no yolo).

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.
