Fix and improve this skill with Tessl
tessl review fix ./container/skills/frontend-engineer/SKILL.mdThe skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
The skill includes an example deployment command that passes a deployment token via a --token CLI argument, which requires inserting a secret value verbatim into generated commands (high exfiltration risk).
