One teaching knot. Three perspectives. One clear next move.

Classroom After Dark is a focused planning room for teachers. A teacher brings the lesson moment that is not landing, convenes an Evidence, Access, and Momentum lens, and leaves with one practical 3–15 minute opener to try tomorrow.

It deliberately avoids fictional students, learner profiles, scores, predictions, and generic-chat sprawl. Instead, it turns one de-identified teaching dilemma into a productive, structured conversation and a usable action card.

How it works

  1. Enter a de-identified lesson topic or classroom dilemma.
  2. Convene the Teaching Council in one click.
  3. Review three concise perspectives and an optional debate where the lenses challenge each other.
  4. Copy Tomorrow's first move: a time-boxed action, teacher language, and evidence to notice.

The product works immediately with deterministic local planning lenses—no account, database, or API key is required. With an OpenAI API key configured, the server creates a tailored, structured GPT-5.6 council from the teacher's topic.

Built with Codex and GPT-5.6

Codex with GPT-5.6 accelerated the redesign from an overlong fictional rehearsal into a production-focused Teaching Council. It was used for the interaction model, typed contract, safe local fallback, structured model route, accessible interface, automated checks, release validation, and narrated demo workflow.

Within the app, GPT-5.6 is used through the OpenAI Responses API to produce a schema-validated council: Evidence, Access, Momentum, two debate exchanges, and a recommendation. The application keeps control of privacy checks, response validation, display, and the action-card format. The model is asked for a move to try—not a prediction, diagnosis, or promise about learners.

Judge quick start

npm install
npm run dev

Open http://localhost:3000, enter a de-identified teaching topic, and select Convene the council. The repository README includes the full setup, model configuration, verification commands, and an explanation of where Codex and GPT-5.6 were used.
