Add recsys-pipeline-architect (Development & Code Tools)

[mturac]

Adds recsys-pipeline-architect under Development & Code Tools.

What it is
A vendor-agnostic Codex skill (agentskills.io standard) for designing composable recommendation, ranking, and feed pipelines using the six-stage Source → Hydrator → Filter → Scorer → Selector → SideEffect framework popularized by xAI's open-sourced For You algorithm (Apache 2.0; this skill is MIT and is an independent reimplementation of the pattern).

Why it fits
Most "recommendation systems" in production aren't exotic ML — they're pipelines. This skill encodes the pattern, walks Codex through eight clarifying steps (use case → sources → hydrations → filters → scorers → selector → side effects → scaffold), surfaces architectural trade-offs (multi-action vs single-score, candidate isolation vs joint, online vs offline batch), and emits a runnable scaffold in the user's stack.

Codex install

git clone https://github.com/mturac/recsys-pipeline-architect.git \
  ~/.codex/skills/recsys-pipeline-architect

Or via skills.sh one-liner: npx skills add mturac/recsys-pipeline-architect (also installs to Claude Code, Cursor, Gemini CLI, and 14 more agents).

Repo contents

• SKILL.md + 5 load-on-demand reference docs (interfaces in 4 languages, multi-action scoring, candidate isolation, filter cookbook with 12 patterns, scorer cookbook)
• 3 runnable example scaffolds, every one green on its test suite:
  • Strapi v5 plugin — TypeScript / Jest, 3/3 pass
  • Zentra-compatible pipeline — Go with generics, 3/3 pass
  • PMAI task prioritizer — Python / FastAPI / pytest, 3/3 pass
• MIT license, attribution to the xAI pattern in README and LICENSE
• v0.1.0 GitHub release tagged
