What its author says it does
Copied from the file, not written here
Apply Build Right engineering principles as a planning, implementation, and review standard. Use when Codex is choosing technologies, service boundaries, storage models, architecture boundaries, splitting modules or features, creating public contracts, changing provider adapters, reviewing implementation quality or over-engineering risk, planning tests, handling side effects, errors, observability, security, or deciding whether markdown guidance needs enforceable checks.

Build Right Engineering Principles
Use this skill as a cross-cutting engineering standard for Build Right projects. It is not a lifecycle phase. It is a review and design lens that other Build Right skills may load when architecture, contracts, implementation boundaries, or engineering-quality tradeoffs matter.
Required Reading
- Read
references/principles.mdbefore making or reviewing changes that touch technology or storage choices, architecture or service boundaries, public contracts, provider adapters, generated code, package ownership, side effects, errors, observability, security, testing strategy, over-engineering risk, or enforceable policy. - Do not load the reference for routine product capture, backlog grooming, or narrow content-only updates unless those topics raise engineering-risk questions.
Operating Mode
- Identify the changed or proposed engineering surface: requirement basis, architecture, module responsibility, dependency direction, contract, adapter, state shape, side effect, failure path, test, evidence, or policy.
- Apply the review checklist from
references/principles.md. - Separate guidance from enforceable authority. Markdown principles are guidance until backed by code, checks, tests, schemas, policy, or evidence.
- Prefer the smallest correction that preserves local patterns and reduces real risk. Do not introduce abstraction only because a principle names one.
- When repeated findings expose a process gap, recommend an enforcement surface instead of adding more prose.
- Record significant architecture or public-contract choices in the target repo's normal decision surface.

User-Visible Status Badge
End every final response with exactly one status badge block:
✅ [DONE] Status: DONE
Decision: <decision/result>
Next action: <next action or none>
Needs user input: <none | concise ask>
Blocked by: <none | blocker>
Use this status map:
✅ [DONE] Status: DONEwhen there are no required changes and no enforcement gap.🟢 [GREEN] Status: ALL GREENwhen the reviewed direction is safe to continue but implementation is not complete.🟡 [YELLOW] Status: NEEDS INPUTwhen a user or owner architecture, contract, security, or policy decision is needed.🟠 [ORANGE] Status: NEEDS WORKwhen AI-owned corrections, tests, docs, or enforcement work remain.🔵 [BLUE] Status: WAITING EXTERNALfor external proof, credentials, production access, publishing, indexing, or third-party state.🔴 [RED] Status: BLOCKEDfor unresolved conflicts, failed validation, source mismatch, invalid state, or enforcement blockers.
