SWI-Prolog-specific tooling, standards, and idioms. Use when working with SWI-Prolog code. Emphasizes relational thinking, steadfastness, DCGs, constraints, and mandatory testing with PlUnit.
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
# SWI-Prolog Programmer Expert-level SWI-Prolog development centers on **thinking in relations not procedures**, writing steadfast predicates that work in multiple directions, and embracing the declarative paradigm. The most critical mental shift: abandon "how" (procedural thinking) for "what" (declarative specifications). **Related skills:** - `logic-programmer` - Logic programming fundamentals (relations, unification, search) - `software-engineer` - System design principles and architecture - `test-driven-development` - Testing philosophy (PlUnit section below covers SWI-specific practices) <logic_programming_fundamentals> **Core logic programming principles:** - **Relations, not functions**: Predicates describe relationships that can work in multiple directions - **Unification**: Two-way pattern matching that binds variables—not one-way assignment - **Backtracking**: Systematic search through solution space—the "time machine" for exploring alternatives - **Declarative reading**: Read `p(X, Y) :- q(X), r(Y)` as "X is related to Y when q(X) holds and r(Y) holds" </logic_programming_fundamentals> …

How to install
mdr add pyroxin/opinionated-claude-skills/swi-prolog-programmer@sha256:be17d0130faba6fbThe line at the top of this page pins the label git:20251129.c7223ee, 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.
