+# Issue #3283 Triage Summary
+
+**Issue:** docs: document OmniRoute OpenAI-compatible setup  
+**Opened by:** @diegosouzapw  
+**Status:** BLOCKED (waiting for clarification)  
+**Date:** 2026-10-13
+
+## Findings
+
+### Investigation
+1. Searched codebase for "OmniRoute" — **no matches found**
+2. Searched documentation (docs/local-openai-compatible-providers.md, MODEL_COMPATIBILITY.md) — **no mentions**
+3. Searched git history (commits, branches, PRs) — **no references**
+4. Checked GitHub API (rate limited, but issue title confirmed)
+
+### Current State
+- Issue #3283 is OPEN
+- No labels assigned
+- Title: "docs: document OmniRoute OpenAI-compatible setup"
+- This is a documentation request for setting up an OpenAI-compatible provider
+
+### Existing Documentation
+The repository already has comprehensive documentation for OpenAI-compatible providers:
+- `docs/local-openai-compatible-providers.md` — documents Ollama, llama.cpp, vLLM, and OpenRouter
+- `docs/MODEL_COMPATIBILITY.md` — model-specific provider routing details
+- `rust/crates/api/src/providers/openai_compat.rs` — provider implementation
+
+## Next Steps
+
+**Action taken:** Comment added to issue asking for:
+1. OmniRoute documentation/website link
+2. OpenAI-compatible endpoint example (base URL, API key format)
+3. Model ID examples
+4. Any special configuration or known quirks
+
+**Comment posted to:** https://github.com/ultraworkers/claw-code/issues/3283#issuecomment-6133484114
+
+## Conclusion
+
+**Cannot proceed without user input.** Once the user provides the necessary information about OmniRoute, the fix will involve:
+1. Adding a new section to `docs/local-openai-compatible-providers.md`
+2. Including setup example (environment variables, model names, basic smoke test)
+3. Following the existing format used for Ollama, llama.cpp, vLLM sections
+4. Creating a PR for review

 mlx-lm serves models under their full Hugging Face repo ID. Use the exact `id` field from `curl $OPENAI_BASE_URL/models` for `--model`. A bare name like `qwen2.5-coder-7b-instruct` will fail model resolution before the request ever reaches the server.
 
+## OmniRoute and other remote OpenAI-compatible gateways
+
+[OmniRoute](https://github.com/diegosouzapw/OmniRoute) is a third-party OpenAI-compatible AI gateway that can route requests to multiple providers. To use any remote OpenAI-compatible gateway with Claw, set `OPENAI_BASE_URL` to the gateway's `/v1` endpoint and provide your API key:
+
+```bash
+export OPENAI_BASE_URL="https://api.omniroute.ai/v1"
+export OPENAI_API_KEY="your-omniroute-api-key"
+claw --model "gpt-4" prompt "Reply exactly HELLO_WORLD_123"
+```
+
+To find the available model IDs on your gateway, use the `/models` endpoint:
+
+```bash
+curl -sS "$OPENAI_BASE_URL/models" \
+  -H "Authorization: Bearer $OPENAI_API_KEY" | jq '.data[].id'
+```
+
+For local configuration, see your gateway's documentation for the correct base URL, API key format, and available model IDs. The same OPENAI_BASE_URL + OPENAI_API_KEY pattern applies to any OpenAI-compatible remote gateway.

 ## Local skills install from disk
 
 Skills are discovered from Claw skill roots such as `.claw/skills/` in a workspace and `~/.claw/skills/` for user-level installs. Legacy `.codex/skills/` roots may also be scanned for compatibility, but new local Claw projects should prefer `.claw/skills/`.
