loop-invariants SKILL.md skillA
loop-invariants from andersonlimahw/lemon-ai-hub is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add andersonlimahw/lemon-ai-hub/loop-invariants@git:20260614.f27dfeaPins git:20260614.f27dfea in mdr.lock. Pin the fingerprint instead.

Universal rules and invariants that every Agentic Value Loop must follow.
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
# Loop Invariants A loop is only "good" if every iteration satisfies **all** of these invariants. 1. **Single increment of real value**: Avoid scope creep; ship something a user notices. (Phase 0 value hypothesis). 2. **Spec before code (SDD)**: No code without a `PLAN.md`. (Phase 1). 3. **Eval defined up front**: Define success before building. 4. **Surgical diff**: Touch only what the request needs. 5. **100% codebase-rule adherence**: Follow Repository Pattern, clean architecture, specific guardrails. 6. **Quality gate green**: `npm run version:validate` MUST exit 0. No exceptions. 7. **PR open + CI green**: Nothing is "done" until CI says so. 8. **Learning captured**: Never repeat a fixed error. Update `ITERATION_LOG.md`. 9. **Automate the second time**: Extract reusable assets so the loop compounds, never repeats toil (Create Skills, Subagents, Scripts).

How to install
mdr add andersonlimahw/lemon-ai-hub/loop-invariants@sha256:53168e9a9c66652aThe line at the top of this page pins the label git:20260614.f27dfea, 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.
