The constitution

📁 Source note: [sage] = upstream Sage repo (github.com/xoai/sage, public) — optional deeper reading; this skill runs fully on the rules inlined here. A step marked MUST READ points at a file in your own project (e.g. an event registry) — if it is missing, stop and ask instead of improvising.

These are the kit's engineering defaults. Read the target project's applicable AGENTS.md and .jimmy/constitution.md if present. The project controls its own workflow and enforcement; a missing optional constitution is not a blocker.

Engineering principles

The base set to apply to relevant changes:

#	Principle	Verification mechanism to use when available
1	Test changed behavior — prefer tests before code for new behavior and regression fixes	Relevant automated tests; editorial changes use inspection/lint
2	No silent failures — errors handled, logged, or propagated	Tests and review of failure paths
3	Secrets never in code — env vars or a secret manager	Secret scan and review
4	Dependencies explicit — declared, pinned by the project's policy	Package manifest/lockfile and dependency checks
5	Changes reversible — migrations and deployments have a recovery path appropriate to risk	Migration/deployment checks and rollback review
