Read the task repository's instructions and explicitly bound Project context.
Then read the bundled [shared router](../../AGENTS.md) and the complete
[canonical workflow](../../.agents/skills/das/validating-das-data/SKILL.md) before acting.
Resolve these paths relative to this skill file, not the working directory.
Follow the router's layer and dependency links. Missing project bindings block
affected operations, not independent local reasoning. Daana CLI is a required
external dependency; do not install it or change credentials implicitly.
