Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00233 |
| Opus 5.5 | $0.00006 | $0.00093 |
| Sonnet 5.5 | $0.00003 | $0.00047 |
| Haiku 4.5 | $0.00002 | $0.00023 |
Grade A, and why
gemini-cli-runtime scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Gemini CLI Runtime
The Gemini companion script (gemini-companion.mjs) is the only way to interact with Gemini CLI from this plugin.
Invocation
All Gemini operations go through a single script:
node "${CLAUDE_PLUGIN_ROOT}/scripts/gemini-companion.mjs" <subcommand> [options]
Subcommands
setup— check readiness and authenticationreview— run a code review against git statetask— run a freeform task (question, delegation, analysis)status— show job statusresult— show completed job resultcancel— cancel an active job
Key Rules
- Never call
geminidirectly — always use the companion script - The companion script manages job tracking, progress logging, and state
- Background tasks are handled via detached worker processes
- All output should be returned verbatim to the user
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.

gemini-cli-runtime is a skill published in the GitHub repository shalomeir/gemini-plugin-cc (4 stars, last pushed 6mo ago), licensed MIT. It adds 16 tokens to every session and 233 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
