Engineering delivery

Pipeline stages, configuration examples, release gates and failure handling.

An on-call checklist, diagnostic branches, recovery verification and review outline.

Component interfaces, state descriptions, implementation drafts and interaction checks.

Three candidate commit subjects, a body and necessary compatibility notes.

A script draft, argument reference, dry-run examples and failure checklist.

An impact table, upgrade sequence, compatibility edits and acceptance checks.

Reviews a Dockerfile for security, image size, build cache use and runtime correctness, and returns ranked findings with a corrected file. Use before shipping an image, or when one is too big.

Wraps new behaviour behind a feature flag with a safe default, a kill switch, tests for both paths and a cleanup ticket. Use when shipping a risky change incrementally.

Plans and adds logs, metrics and traces using OpenTelemetry conventions, golden signals, useful log fields, cardinality limits and first dashboards. Use when a service is hard to debug in production.

Writes an onboarding guide for a repository covering setup, an architecture map, first tasks and known gotchas, with every command checked against the repo. Use for new hires or contributors.
