At a glance

Finds models on the Hugging Face router that lack descriptions in chat-ui's prod.yaml and dev.yaml, researches each one and adds short descriptions.

  • Works in 7 steps: Fetch models from router → Read current configuration → Identify missing models → …
  • New models have appeared on the Hugging Face router and the chat-ui config lacks them
  • SKILL.md covers Workflow and Notes
  • Calls git; reaches router.huggingface.co

What it does

The workflow fetches the model list from router.huggingface.co/v1/models, reads chart/env/prod.yaml and pulls the model IDs out of its MODELS JSON array. Any ID present on the router but absent from the file counts as missing. Each missing model is then researched on the web for its architecture, key capabilities and target use cases.

Descriptions follow the existing house style: eight to twelve words, sentence fragments, no articles unless needed, centered on architecture, specialization and key capability. New entries go at the top of the MODELS array in both prod.yaml and dev.yaml as id and description pairs, and the change is committed with a message that states how many models were added. Notes cover FP8 variants, vision-language models, agent models and regional language focus.

When your agent uses it

  • New models have appeared on the Hugging Face router and the chat-ui config lacks them
  • Syncing prod.yaml and dev.yaml with the router's current model list
  • Writing short, consistent one-line descriptions for model entries

Example prompts

  • “Add descriptions for any new models on the router to prod.yaml and dev.yaml.”
  • “Sync models from the router and commit the updated chat-ui configs.”
  • “Which router models are missing from chart/env/prod.yaml? Describe them and add them.”

Requirements

  • A chat-ui checkout with chart/env/prod.yaml and dev.yaml
  • Network access and web search

Workflow steps

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

  1. Fetch models from router
  2. Read current configuration
  3. Identify missing models
  4. Research each missing model
  5. Write descriptions
  6. Update both files
  7. Commit changes

What it can do on your machine

Read from SKILL.md and the folder at commit 58e0ae7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • router.huggingface.co

    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

Add Model Descriptions loads about 600 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 214 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~600

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.

name
add-model-descriptions
description
Add descriptions for new models from the HuggingFace router to chat-ui configuration. Use when new models are released on the router and need descriptions added to prod.yaml and dev.yaml. Triggers on requests like "add new model descriptions", "update models from router", "sync models", or when explicitly invoking /add-model-descriptions.

Add Model Descriptions

Add descriptions for new models available in the HuggingFace router to chat-ui's prod.yaml and dev.yaml.

Workflow

  1. Fetch models from router

    WebFetch https://router.huggingface.co/v1/models

    Extract all model IDs from the response.

  2. Read current configuration

    • Read chart/env/prod.yaml
    • Extract model IDs from the MODELS JSON array in envVars

  3. Identify missing models Compare router models with prod.yaml. Missing = in router but not in prod.yaml.

  4. Research each missing model For each missing model, search the web for its specifications:

    • Model architecture (dense, MoE, parameters)
    • Key capabilities (coding, reasoning, vision, multilingual, etc.)
    • Target use cases

  5. Write descriptions Match existing style:

    • 8-12 words
    • Sentence fragments (no period needed)
    • No articles ("a", "the") unless necessary
    • Focus on: architecture, specialization, key capability

    Examples:

    • "Flagship GLM MoE for coding, reasoning, and agentic tool use."
    • "MoE agent model with multilingual coding and fast outputs."
    • "Vision-language Qwen for documents, GUI agents, and visual reasoning."
    • "Mobile agent for multilingual Android device automation."

  6. Update both files Add new models at the TOP of the MODELS array in:

    • chart/env/prod.yaml
    • chart/env/dev.yaml

    Format:

    json
    { "id": "org/model-name", "description": "Description here." }

  7. Commit changes

    git add chart/env/prod.yaml chart/env/dev.yaml
git commit -m "feat: add descriptions for N new models from router"

Notes

  • FP8 variants: describe as "FP8 [base model] for efficient inference with [key capability]"
  • Vision models: mention "vision-language" and key visual tasks
  • Agent models: mention "agent" and automation capabilities
  • Regional models: mention language focus (e.g., "European multilingual", "Southeast Asian")

What does Add Model Descriptions do?

Finds models on the Hugging Face router that lack descriptions in chat-ui's prod.yaml and dev.yaml, researches each one and adds short descriptions. yaml and pulls the model IDs out of its MODELS JSON array. Any ID present on the router but absent from the file counts as missing.

When should I use Add Model Descriptions?

Add Model Descriptions fits situations like: new models have appeared on the Hugging Face router and the chat-ui config lacks them; syncing prod.yaml and dev.yaml with the router's current model list; writing short, consistent one-line descriptions for model entries.

How do I install Add Model Descriptions in Claude Code?

Run `npx skills add ruvnet/ruflo --skill add-model-descriptions -a claude-code`. Or copy the skill folder (ruflo/src/ruvocal/.claude/skills/add-model-descriptions in ruvnet/ruflo) into .claude/skills/add-model-descriptions in your project. Claude Code loads it when a task matches its description.

How do I install Add Model Descriptions in Codex?

Run `npx skills add ruvnet/ruflo --skill add-model-descriptions -a codex`. Or copy the skill folder (ruflo/src/ruvocal/.claude/skills/add-model-descriptions in ruvnet/ruflo) into .agents/skills/add-model-descriptions in your project. Codex loads it when a task matches its description.

Can I use Add Model Descriptions 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 add-model-descriptions -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/add-model-descriptions, .gemini/skills/add-model-descriptions, .github/skills/add-model-descriptions and .opencode/skills/add-model-descriptions in your project.

What does Add Model Descriptions need to run?

Going by SKILL.md and its folder, Add Model Descriptions needs the command-line tools its instructions call (git). Our summary lists: A chat-ui checkout with chart/env/prod.yaml and dev.yaml; Network access and web search.

Does Add Model Descriptions access the network?
