# SG-FLW Web Tool

[![skills.sh](https://img.shields.io/badge/skills.sh-sg--flw--classifier-111827.svg)](https://github.com/ezefranca/sg-flw/tree/main/skills/sg-flw-classifier)

SG-FLW is an academic measurement framework for coding and planning evidence quality in serious games, games, and gamified interventions addressing food loss and waste. The tool profiles five dimensions:

- B: Baseline measurement quality
- K: Knowledge and attitudinal assessment
- D: Direct behavior measurement
- E: Environmental conversion
- L: Persistence / longitudinal measurement

The tool evaluates measurement-chain strength, not intervention quality, game quality, or causal effectiveness. A low SG-FLW profile means that evidence is missing or weakly reported; it does not mean the intervention failed.

## SG-FLW Classifier Skill

The repository hosts a Codex / SKILL.md-compatible classifier skill at `skills/sg-flw-classifier/`. It helps AI agents classify papers, protocols, and boundary cases in serious games and food waste research under SG-FLW without over-crediting awareness outcomes, in-game outputs, or modeled environmental indicators as measured food-waste reduction evidence.

The skill includes separate reference files for SG-FLW foundations, the detailed coding protocol, the published reference corpus, a source-linked corpus knowledge base, and prospective study/telemetry planning. Agents should read those files before assigning B/K/D/E/L scores.

Install with the `skills` CLI:

```bash
npx skills add https://github.com/ezefranca/sg-flw --skill sg-flw-classifier
```

Install globally for Codex:

```bash
npx skills add https://github.com/ezefranca/sg-flw \
  --skill sg-flw-classifier \
  -a codex \
  -g \
  -y
```

Installation instructions are available on `skill.html`.

The skill page documents installation for Codex/OpenAI agent setups, Claude Code, Cursor, GitHub Copilot, upload-based clients, and custom SKILL.md-compatible directories. A ZIP package is available at `downloads/sg-flw-classifier-skill.zip` for clients that support custom skill upload.
