Dex handles small codebase work with receipts.

Website edits, dependency updates, bug fixes, QA fixes, maintenance tasks and pull requests. Dex is not a vague coding assistant. Dex gets a work order, runs in a controlled context, and leaves proof.

Dex restored Dex naming on the canonical site

Dex keeps dexcode.ai as the canonical host while public copy, metadata, robot links and tests use Dex consistently after the canonical host audit.

Dex moved agent workflows toward Codex CLI

Agent workflows now prefer the Codex CLI runner path, with shared selection, authentication setup, and run scripts documented for scheduled and manual automation.

Dex widened the engineering quality gate

CI now runs RSpec, deploys gate on that job, robot advanced pages avoid a JSONB N+1 query, receipt cards eager-load robot data, and missing public-page meta descriptions were filled in.
