Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00079 | $0.00626 |
| Opus 5.5 | $0.00032 | $0.00250 |
| Sonnet 5.5 | $0.00016 | $0.00125 |
| Haiku 4.5 | $0.00008 | $0.00063 |
Grade A, and why
agent-operator-claude-setup 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.
How it starts
The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Operator Claude Setup
Use Claude Code's native plugin manager. The procedure below is self-contained because installed plugin caches do not include repository-root documentation.
Install
-
Confirm
gitandclaudeare available. -
Add the marketplace inside Claude Code:
/plugin marketplace add gabonio/agent-operator-toolkit -
Install only the requested plugins:
/plugin install agent-operator-setup@agent-operator-toolkit /plugin install builder-kit@agent-operator-toolkit -
Run
/reload-pluginsto activate changes without restarting Claude Code.
Direct installs use user scope by default. To choose user, project, or local scope, use /plugin, open Discover, select the plugin, and choose the scope. Do not select project scope without authorization because it updates repository configuration.
Update
-
Run
/plugin marketplace listand confirm the registered marketplace name. -
Refresh it with
/plugin marketplace update agent-operator-toolkit. -
Update each installed plugin that the user wants to refresh:
/plugin update agent-operator-setup@agent-operator-toolkit /plugin update builder-kit@agent-operator-toolkit -
Run
/reload-plugins. -
If an installed plugin remains unchanged, verify that its published version was bumped.
Third-party marketplace auto-updates are disabled by default. Enable them only when the user requests it through /plugin → Marketplaces → Agent Operator → Enable auto-update.
Diagnose
-
Inspect the Marketplaces, Installed, and Errors tabs under
/plugin. -
Run
/reload-pluginsafter installation, update, enable, or disable operations. -
From this plugin root, run the read-only doctor:
python3 scripts/doctor.py --client claude -
Pass
--marketplace-root <path>when diagnosing a local checkout.
Do not delete ~/.claude/plugins/cache automatically. Cache removal is destructive local recovery and requires explicit user confirmation after native update and reload paths fail.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

agent-operator-claude-setup is a skill published in the GitHub repository gabonio/agent-operator-toolkit (1 stars, last pushed 7d ago), licensed MIT. It adds 79 tokens to every session and 626 once invoked, about $0.0003 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.

autoreview
Structured code review through the shared OpenClaw agent-skills installation.
omh-code-review
This is an OMH code-review workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
revdiff-plan
Review the last Codex assistant message (plan, analysis, or proposal) with inline annotations in a TUI overlay. Extracts the most recent response from Codex rollout files and opens it in revdiff for review and annotation. Activates on "revdiff-plan", "review plan with revdiff", "annotate plan", "review last response"…
re0-merge
Review and land an external contribution the way this suite does: gate it against the thesis, land it with the author's credit intact, complete a new skill rather than merging it raw, then approve, credit, and explain before closing. Use when reviewing a pull request, as any collaborator or maintainer, not only the…

Guide the user through a quadrant walk that maps the unknowns of a task — open by listing the known knowns, then work through known unknowns, unknown knowns, and unknown unknowns one stage at a time, ending with a complete four-quadrant map in the user's hands.
