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. The Agent Skill page on snapgen.org builds the exact install command for your agent and scope.

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.
