What it does
Smart Router is an agent skill from databricks/unity-gateway, published by the product's own GitHub organization. Enable or disable Unity Gateway subagent model routing for the current smart-routed Claude or Codex session, along with Smart Router Orchestrator when opted in.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Model routing and gateways and Subagents. It works with Python.
When your agent uses it
- Tasks that involve Model routing and gateways
- Tasks that involve Subagents
Example prompts
- “/smart-router”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli claude --enable-smart-routing), Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli claude --disable-smart-routing), Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli codex --enable-smart-routing), Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli codex --disable-smart-routing)
What it can do on your machine
Read from SKILL.md and the folder at commit 2ff1d8a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli claude --enable-smart-routing)Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli claude --disable-smart-routing)Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli codex --enable-smart-routing)Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli codex --disable-smart-routing)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Smart Router loads about 590 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 231 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 231 words (~590 tokens).
“Use the Python executable exported by the launching Unity Gateway installation. Keep its path quoted and do not substitute ug or python from PATH.”

Enable or disable Unity Gateway subagent model routing for the current smart-routed Claude or Codex session, along with Smart Router Orchestrator when opted in.
When should I use Smart Router?
Smart Router fits situations like: tasks that involve Model routing and gateways; tasks that involve Subagents.
How do I install Smart Router in Claude Code?
Run `npx skills add databricks/unity-gateway --skill smart-router -a claude-code`. Or copy the skill folder (skills/smart-router in databricks/unity-gateway) into .claude/skills/smart-router in your project. Claude Code loads it when a task matches its description.
How do I install Smart Router in Codex?
Run `npx skills add databricks/unity-gateway --skill smart-router -a codex`. Or copy the skill folder (skills/smart-router in databricks/unity-gateway) into .agents/skills/smart-router in your project. Codex loads it when a task matches its description.
Can I use Smart Router in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add databricks/unity-gateway --skill smart-router -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/smart-router, .gemini/skills/smart-router, .github/skills/smart-router and .opencode/skills/smart-router in your project.
What does Smart Router need to run?
SKILL.md names no scripts, command-line tools or credentials: Smart Router is instructions for the agent only. Our summary lists: Python 3. Its frontmatter pre-approves these tools: Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli claude --enable-smart-routing), Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli claude --disable-smart-routing), Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli codex --enable-smart-routing), Bash("$UCODE_SMART_ROUTER_PYTHON" -m ucode.cli codex --disable-smart-routing).
Does Smart Router access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Smart Router safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Smart Router use?
Smart Router has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Smart Router use?
About 590 tokens (SKILL.md is roughly 2.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Smart Router?
Skills that share tags, products or a category with Smart Router: Pydantic AI Harness (pydantic/pydantic-ai, 20k stars), Agent Squad Python Guide (2FastLabs/agent-squad, 7.8k stars), Agent Builder (shareAI-lab/lab-skills, 314 stars) and Agent Harness Builder (FareedKhan-dev/claude-code-from-scratch, 298 stars).
