Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install dpop-token-binding

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 generates a non-extractable P-256 key pair, produces DPoP proof JWTs for the code exchange and token refresh, and handles the use_dpop_nonce retry. It follows the architecture rules for browser apps and BFF backends. It does not cover unconstrained OAuth flows or Google Cloud IAM.
