Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install agent-prompt-budget-check

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent estimates the context the sub-agent will inherit (CLAUDE.md, memory, tools), applies the minimal five-section template and runs a checklist before sending. You get a sub-agent prompt sized to fit, with no overflow rejection.
