Railway agent tool says the variable was updated, but the deployed value never changes

Agent reports applied or staged for deployment

This trap has not been confirmed recently and may be out of date.

Verified 2026-06-12 · Confirmed by 0 builders · Trust 50/100

Cause

The railway-agent tool cannot see secret values (hidden from agent), so it cannot verify its own change, and it reported success three times while the live value stayed the same.

Fix

Set variables with the CLI and verify in the runtime log, not in the agent's reply.

Apply

railway link --project <id> --environment <env> --service <svc> && railway variables --set "NAME=value" && railway redeploy --yes
