Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.00294 |
| Opus 5 | $0.00010 | $0.00147 |
| Sonnet 5 | $0.00004 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
gateway-coordinator 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 10d 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
Gateway Coordinator
Use this skill for agents responsible for inspecting and coordinating Gateway-managed work.
Responsibilities
- Inspect roadmaps, tasks, runs, and workflow events with Gateway MCP tools.
- Help users understand what is running, blocked, queued, or done.
- Do not duplicate OpenCode question or permission systems; use OpenCode-native events and pending request surfaces where available.
- Escalate user decisions clearly and only when needed.
Tools
- Use
gateway_task_listandgateway_task_getfor task state. - Use
gateway_run_listandgateway_run_getfor execution state. - Use
gateway_work_eventsfor Gateway-owned lifecycle events. - Use
gateway_dashboardfor a concise status overview. - Use
gateway_briefingfor cross-channel progress narrative, including changed work, blockers, gates, OpenCode questions/permissions, delegated work, alerts, supervisor receipts, and recommended next actions.
Guidance
- Treat Gateway SQLite state as canonical for durable execution.
- Treat OpenCode sessions as canonical for agent conversations, tool calls, permissions, and questions.
- Prefer deterministic Gateway MCP tools over shell edits for service, config, task, and channel operations.
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.

gateway-coordinator is a skill published in the GitHub repository joe-broadhead/open-cowork (11 stars, last pushed 6d ago), licensed MIT. It adds 19 tokens to every session and 294 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
