vLLM chat-template (prompt-side Jinja) operator reference. Template resolution precedence (`--chat-template` → AutoProcessor → tokenizer default → bundled fallback), `chat_template_kwargs` allowlist silently dropping `add_generation_prompt`/`enable_thinking`/custom kwargs (PR 27622 fix), 27 shipped `tool_chat_template_*.jinja` files, known template-layer bugs for Qwen3/Qwen3-Coder, DeepSeek-R1/V3/V3.1/V3.2, GPT-OSS, Kimi-K2, Llama-4, Mistral (HF vs mistral mode), Gemma-3/4, Phi-4, GLM.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# vLLM chat templates — operator triage Target audience: operators deploying vLLM in production. Assumes OpenAI-API-compatible frontend (`/v1/chat/completions` or `/v1/responses`), multi-GPU, mid-2024 through 2026 model families. ## Scope — three sibling skills, three layers Chat-template bugs span three layers. This skill owns the **prompt-rendering** layer; route to a sibling when the problem is output-side. | Layer | Direction | Skill | What it covers | |---|---|---|---| | **Chat template (Jinja)** | messages → prompt string | **this skill** | template precedence, `--chat-template`, `chat_template_kwargs`, `examples/tool_chat_template_*.jinja`, bundled fallbacks | | **Reasoning parser** | model output → `reasoning_content` + `content` | `vllm-reasoning-parsers` | `--reasoning-parser`, `extract_reasoning`, `is_reasoning_end`, `<think>` splitting | | **Tool parser** | model output → `tool_calls[]` | `vllm-tool-parsers` | `--tool-call-parser`, streaming state machines, partial-JSON parsing | …

How to install
mdr add air-gapped/skills/vllm-chat-templates@sha256:b6927979020340caThe line at the top of this page pins the label git:20261018.35a61a4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
