Apply the Cratis effect-boundary contract when writing or reviewing code that publishes, persists, generates, propagates, or releases. On those boundaries partial success is failure - no catch-and-continue, no defaulting to success on an unknown outcome. Use when a degraded run could still report success; defer style questions and specification authoring to their own workflows.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Effect boundaries fail loudly An **effect boundary** is the point where work leaves the process and becomes something other people observe: a package published, a row written, a file generated, content propagated to other repositories, a release cut. The contract: > On an effect boundary, **partial success is failure.** No catch-and-continue, > no defaulting to success on an unknown outcome. A degraded operation must fail > the operation, surface the delta, or emit an explicit degraded-mode signal. Silent failure is the dominant recurring bug archetype across Cratis. The 2026-08-24 organization-wide review found one disease with six manifestations, in the release action, the Arc proxy generator, Stage, the Chronicle container host, Chronicle constraint enforcement, and corpus propagation. They are written out in [failure-archetypes.md](references/failure-archetypes.md); read them before deciding that your case is different. ## When you need this - You are writing or reviewing a `catch` around an operation with an effect — publish, write, generate, copy, notify, tag, release. - An operation processes a set and some members can fail independently: a …

How to install
mdr add cratis/ai/cratis-engineering-effect-boundaries@sha256:6aaa05d8f59ac208The line at the top of this page pins the label git:20260911.ef70ec9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
