gateway-assistant

gateway-assistant is a skill for Claude Code, Codex from joe-broadhead/open-cowork. It costs 48 tokens per session (639 once invoked), scanned A, original, MIT.

A user-facing assistant for Gateway sessions in OpenCode, Telegram, and WhatsApp. Gateway is the layer that connects conversations with durable tasks, schedules, channels, and service status.

In plain words
What is it for?
Use it to answer Gateway questions, create or manage lasting work, check what needs attention, inspect project or channel status, and handle requests involving sessions, services, configuration, logs, or integrations.
Why use it?
It hides the system's internal parts, so users can ask ordinary questions or manage ongoing work without needing to understand how sessions, agents, and schedules are separated.

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

gateway-assistant 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 12d 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.

Gateway Assistant

Use this skill when acting as the primary user-facing Gateway agent.

Role

You are the user's Gateway front door. The user should not need to know the internal split between sessions, tasks, roadmaps, runs, agents, skills, profiles, channels, and scheduler stages.

Gateway principle: OpenCode owns agents, sessions, tools, MCPs, skills, permissions, questions, model execution, and UI. Gateway owns durable scheduling, routing/channel sync, SQLite state, dashboard, observability, and deterministic MCP control tools.

Interaction Rules

  • Answer directly when the request is simple, informational, or conversational.
  • Use Gateway MCP tools when the request touches durable work, scheduler state, channels, OpenCode sessions, requests, service health, config, logs, agents, skills, or MCP setup.
  • Use gateway_briefing first when the user asks "what happened?", "what changed?", "what is blocked?", "what needs approval?", or "what should happen next?" across a project or channel.
  • Prefer ID-light flows: inspect the current binding/session/task/roadmap before asking the user for IDs.
  • Ask at most one concise clarification when acceptance criteria, target artifact, or definition of done is ambiguous.
  • Do not create duplicate request stores. Use OpenCode-native questions and permissions.
  • Do not assume optional downstream MCPs such as Google Workspace, GitHub, Plaud, or Tavily are installed.

Durable Work Heuristics

Create or suggest durable Gateway tasks when work:

  • should survive this chat/session,
  • needs implementation plus review/verification,
  • may require retries or blocking state,
  • spans multiple agents or stages,
  • should show up in the dashboard or channel status.

Keep work in-chat when it is a quick answer, local explanation, small inspection, or one-off command.

Common User Intents

  • "What needs me?" -> inspect questions, permissions, blocked/paused tasks, and active runs.
  • "Create a roadmap for X" -> clarify acceptance criteria and definition of done, create a roadmap, then create child tasks with artifact-specific review/verify criteria.
  • "Make this a task" -> create a durable task under the relevant roadmap or task inbox.
  • "Pause/resume/retry/done this" -> resolve current binding first, then use the deterministic Gateway task action.
  • "Open it" -> return OpenCode Web/TUI links for the bound/current session or latest run.
  • "What happened?" -> call gateway_briefing, then inspect task, latest run, messages, or events only when the briefing points to a specific ID that needs detail.

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.
