Ingredients but no dinner idea? Prototype a recipe filter

Use Codex with fictional inventory and authorized recipes to prepare a testable recipe-filter prototype through the test workflow below, then review it. Matching tools and permissions are required.

Execution environment and usage

AI / software

Codex

Where to operate

Codex CLI in a terminal, opened in a separate test folder.

Getting started

  1. Follow the linked official Codex CLI setup guide; open a terminal in the test folder, run codex and sign in.
  2. Supply fictional inventory and authorized recipes and the prompt below. Confirm the scope before allowing necessary actions.
  3. Inspect the resulting testable recipe-filter prototype; record anything not run or not verified.

Setup and plan requirements

Requires access to Codex, authorized test data and a matching runtime; file writes and shell commands must stay within approved scope. Preparation: Prepare fictional inventory, recipes you may use and a test environment, without household health records.

Prompt portability limits

Adapt the wording to another coding assistant only after separately configuring files, runtime, test tools and integrations. Renaming the tool does not establish compatibility.

Usage limitations

This workflow was not hands-on tested. Work on test copies; no automatic publishing, payment or production-data changes. Separate plans, actual results and untested areas.

Environment sources

適用情境 / When to use

Use Codex with fictional inventory and authorized recipes to prepare a testable recipe-filter prototype through the test workflow below, then review it. Matching tools and permissions are required. Deirdre Straughan reports building a local dinner-suggestion app with Codex using pantry items and household preferences.

步驟 / Steps

  1. Prepare fictional inventory, recipes you may use and a test environment, without household health records.
  2. Start with ingredient-to-recipe matching and configurable portions, time, equipment and exclusions.
  3. Check units, missing ingredients and food condition manually; test empty stock and incompatible units.

提示詞 / Prompt

Build a dinner-filter prototype in [local test environment] using [fictional inventory and authorized recipes] with [portions, time, equipment, preferences and exclusions]. Flag missing ingredients and unclear units; do not infer allergen safety. Deliver a small testable version without health-data connections, shopping or publication.

留意事項 / Cautions

  • Expiry dates do not guarantee safety; allergens need manual checking.
  • This prototype provides no medical diet advice and places no orders.

來源限制 / Evidence limits

This personal project has no nutrition or food-safety validation; the author also describes instability from expanding scope.

流程說明 / Workflow note

These steps and prompts are original, untested exercises by this site, not the author’s verbatim workflow. Reported results do not guarantee exercise outcomes.

原始工具組合 / Original tool stack

Codex; ChatGPT for initial planning; local Python / FastAPI / SQLite app
