Catalogue of known SDLC anti-patterns that great_cto agents must actively reject when reviewing architecture, plans, code, or post-mortems. Used by architect (pre-impl), pm (planning), senior-dev (impl), l3-support (post-incident).
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
# SDLC anti-patterns to reject Reference catalogue. Cite the anti-pattern by name when blocking a proposal — gives the user a clear vocabulary to discuss the issue. ## Architecture anti-patterns ### A-1. God service **Smell:** One service does auth, billing, search, file storage, and email. **Why bad:** Single deploy unit, single point of failure, every team touches it, change velocity drops over time. **Fix:** Split by business capability (DDD bounded context). ### A-2. Distributed monolith **Smell:** 12 microservices but they share a database and deploy together. **Why bad:** All cost of distributed (latency, eventual consistency, ops overhead) with none of the benefits (independent deploy, isolation). **Fix:** Either truly separate (own DB, own deploy pipeline) or merge. ### A-3. Synchronous chains **Smell:** Request → Service A → Service B → Service C → Service D. **Why bad:** Compound failure probability, p99 latency adds up. **Fix:** Async with events, or co-locate hot path. ### A-4. Premature optimization **Smell:** Custom Redis Lua scripts, hand-tuned binary protocols, before the first paying user. **Why bad:** Complexity cost paid up front, never recouped. …

How to install
mdr add avelikiy/great_cto/anti-patterns@sha256:cdf41fea9aaa1f7eThe line at the top of this page pins the label git:20260921.0ea58e1, 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.
