Format prompts for different LLM providers with chat templates and HNSW-powered context retrieval

  • Works in 5 steps: Format chat — call… → Create HNSW index — call… → Add documents — call… → …
  • Tasks that involve Vector databases
  • SKILL.md covers When to use, Steps and Supported providers
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Chat Format is an agent skill from ruvnet/ruflo. Format prompts for different LLM providers with chat templates and HNSW-powered context retrieval

Its SKILL.md is about 360 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 Databases, covering Vector databases. It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.

When your agent uses it

  • Tasks that involve Vector databases

Example prompts

  • “/chat-format”

Requirements

  • Pre-approved tools (allowed-tools): mcp__plugin_ruflo-core_ruflo__ruvllm_chat_format, mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_create, mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_add, mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_route, mcp__plugin_ruflo-core_ruflo__ruvllm_status, Bash

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Format chat — call mcpplugin_ruflo-core_rufloruvllm_chat_format with messages and target provider
  2. Create HNSW index — call mcpplugin_ruflo-core_rufloruvllm_hnsw_create for context retrieval
  3. Add documents — call mcpplugin_ruflo-core_rufloruvllm_hnsw_add to index documents
  4. Route query — call mcpplugin_ruflo-core_rufloruvllm_hnsw_route to find relevant context
  5. Check status — call mcpplugin_ruflo-core_rufloruvllm_status for provider availability

What it can do on your machine

Read from SKILL.md and the folder at commit de590e1. 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:

    • mcp__plugin_ruflo-core_ruflo__ruvllm_chat_format
    • mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_create
    • mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_add
    • mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_route
    • mcp__plugin_ruflo-core_ruflo__ruvllm_status
    • Bash

    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

Chat Format loads about 362 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 101 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~362

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: mcp__plugin_ruflo-core_ruflo__ruvllm_chat_format, mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_create, 

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.

Chat Format

Format prompts for multi-provider LLM inference with context retrieval.

When to use

When preparing prompts for different LLM providers (Claude, GPT, Gemini, Ollama) or building RAG pipelines with HNSW-powered context retrieval.

Steps

  1. Format chat — call mcp__plugin_ruflo-core_ruflo__ruvllm_chat_format with messages and target provider
  2. Create HNSW index — call mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_create for context retrieval
  3. Add documents — call mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_add to index documents
  4. Route query — call mcp__plugin_ruflo-core_ruflo__ruvllm_hnsw_route to find relevant context
  5. Check status — call mcp__plugin_ruflo-core_ruflo__ruvllm_status for provider availability

Supported providers

  • Anthropic (Claude) — native format
  • OpenAI (GPT) — chat completion format
  • Google (Gemini) — generative AI format
  • Ollama — local model format
  • Cohere — generate/chat format

Can I use Chat Format 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 ruvnet/ruflo --skill chat-format -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/chat-format, .gemini/skills/chat-format, .github/skills/chat-format and .opencode/skills/chat-format in your project.

What does Chat Format need to run?

SKILL.md names no scripts, command-line tools or credentials: Chat Format is instructions for the agent only.
