## How to choose and use a skill
Choose and install the appropriate skills in my current project, then use them to complete the task I describe next.
Read https://agenttaste.dev/skills.json?category=payments.
Choose skills by their useWhen, inputs, prerequisites and expected outputs.
Read the full SKILL.md and any referenced upstream files before using a skill.
Explain the chosen skills and check that their prerequisites and access terms are met.
Use the installation instructions for the agent running this task.
Use the listed project installation command or the documented plugin setup. Inspect existing installed skills before modifying them, and keep companion rules and scripts together.
Do not invent packages, search metrics, credentials or compatibility. If a required tool is unavailable, say which prerequisite is missing.
Then apply the chosen skill to my task and verify the result against the project instructions.
