Agent Skill

snapgen-ai-models is an Agent Skill for coding agents. It teaches the agent one reliable path from a request to a delivered result: find models in the live catalog, read the schema and price before paying, pick MCP or the CLI, submit once, keep the task id, poll to a final status, and report the model, status, charge and outputs.

Install

# current project
npx skills add snapgen-ai/snapgen-devtools --skill snapgen-ai-models

# all projects for this user
npx skills add snapgen-ai/snapgen-devtools --skill snapgen-ai-models -g

The installer needs Node.js 22.20 or newer; the SnapGen CLI needs Node.js 20. Reload or restart your coding client afterwards so it discovers the skill.

Give it an execution path

The skill works through either:

the hosted MCP server (https://api.snapgen.org/mcp), or
the CLI (npx -y @snapgen/cli).

Set your key as SNAPGEN_API_KEY or run snapgen auth login. Never put the key in a prompt, a file or a repository.

Verify without a paid task

Ask your agent:

Confirm that the snapgen-ai-models skill is loaded and say whether you will use
the SnapGen MCP tools or the SnapGen CLI. List the current image-to-video
models with their input requirements and public prices. Do not submit any job.

What the skill enforces

Rule	Why
Look up model ids live	Model ids and prices change; guessed ids fail.
Read schema and price first	The agent can state the expected cost before spending.
Submit once with an idempotency key	A retried submission returns the same task.
Never call waiting complete	`queued` and `processing` are not results.
Never retry blindly	Check the task and balance before a new attempt, which is a new charge.
Report a receipt	Model, final status, charge in USD, outputs and task id.

The skill never replaces the live catalog, prices or task status; it tells the agent when and how to read them.
