Warp Key-Value Expansion

/warp-deploy-select-keys writes a per-ticket key-context artifact (~/.hyperlane/key-contexts/<ticket-id>.yaml) with, per protocol, a keys.<protocol>.name, keys.<protocol>.source, and derived keys.<protocol>.address. Every downstream skill that runs a signing CLI command references a key as a <KEY_<PROTOCOL>_VALUE> placeholder and must expand it the same way — this skill is the single source of that mapping so the copies can't drift.

Expansion legend

Substitute <KEY_<PROTOCOL>_VALUE> (e.g. <KEY_ETHEREUM_VALUE>, <KEY_SEALEVEL_VALUE>) per the artifact's source field for that protocol:

pnpm --silent is mandatory for any --key.<protocol> command

Always invoke the CLI via pnpm --silent … for any command that takes a --key.<protocol> flag. Without --silent, pnpm prints an execution banner of the form $ node ./dist/cli.js <cmd> … --key.ethereum 0x<rawkey> after shell substitution — that banner echoes the resolved argv (including the raw key) into stdout, defeating the gcloud secrets versions access / cat substitution that is supposed to keep the raw key out of logs. --silent suppresses the banner entirely. This is non-negotiable for sign commands; the leak applies to every --key.<protocol> flag in the warp-deploy/update chain.

Disclose the key at every [CONFIRM:] gate

Before any [CONFIRM:] gate that precedes a signing command, display the resolved secret NAME (or env-var name) and the corresponding derived address from the artifact. The human approving the gate must see both — which key was picked, and which signer that key produces. That disclosure is the safeguard against wrong-key foot-guns; never show the raw key value itself.

Consumers

/warp-deploy-select-keys (its own address-derivation commands), /warp-deploy-validate-owners, /warp-deploy-init-route, /warp-deploy-update-owners, /warp-update, /warp-update-extend — every skill that expands a --key.<protocol> flag.
