# AI use cases for Codex Bridge (Sateezg/codex-bridge) Repo: [Sateezg/codex-bridge](https://github.com/Sateezg/codex-bridge) | Use cases: 4 | Page: https://dedupedai.com/use-cases/sateezg-codex-bridge/ A Claude Code plugin that adds image generation (gpt-image-2) and GPT-5 subagents by calling the Codex CLI through your existing ChatGPT login, with no OpenAI API key. This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Generate a project image from a text prompt: https://dedupedai.com/use-cases/sateezg-codex-bridge/generate-image-for-a-project/ - Build a matching favicon and OG card set: https://dedupedai.com/use-cases/sateezg-codex-bridge/favicon-and-og-card-set/ - Delegate a repo-wide rename to GPT-5: https://dedupedai.com/use-cases/sateezg-codex-bridge/bulk-rename-via-codex-implementer/ - Run a GPT-5 review of a branch diff: https://dedupedai.com/use-cases/sateezg-codex-bridge/gpt5-diff-review-from-shell/ ## How to generate a project image from a text prompt with Codex Bridge Repo: [Sateezg/codex-bridge](https://github.com/Sateezg/codex-bridge) | Difficulty: Intermediate | Time: 15 minutes | Basis: From the README Create an icon, mockup, or hero image with gpt-image-2 and save it to your repo. **Who it is for:** A developer building a landing page or app who needs a new image that does not exist yet. **The problem:** Claude Code cannot generate images, and asking a chat window for one means copying files by hand. **The outcome:** A PNG file saved at a path you chose, with the path printed by the wrapper. ### Steps 1. Install the Codex CLI with `npm i -g @openai/codex` or `brew install codex`. 2. Sign in with `codex login`, then check it with `codex login status`. 3. Install the plugin with `/plugin marketplace add Sateezg/codex-bridge` and `/plugin install codex-bridge@codex-bridge`. 4. Run `codex-imagegen "flat vector rocket icon, #2563EB on white, 2px stroke, minimal" ./rocket.png`. 5. Open the PNG to check it, then run again with `--ref ./rocket.png` to adjust the style. (inferred, check the README) ### Prompt to paste into your agent ```text In the Sateezg/codex-bridge plugin setup, run codex-imagegen with the prompt "" and save the result to .png. Report the absolute path the wrapper prints. Verify that the file exists and opens as a PNG before reporting success. ``` ### Caveat Image turns use ChatGPT plan quota roughly 3 to 5 times faster than text turns, and setting OPENAI_API_KEY switches Codex to API billing.

Complete the install steps for the Codex CLI, `codex login`, and the plugin. 2. Install ImageMagick so the size variants can be made locally. (inferred, check the README) 3. In Claude Code, ask: set up favicons and an OG card for this project. 4. Generate a large square master with `codex-imagegen` and pass earlier icons with `--ref` so the style carries over. 5. Review each output image and ask Claude to regenerate any that miss the style. ### Prompt to paste into your agent ```text In the Sateezg/codex-bridge plugin setup, generate a square master icon for with codex-imagegen, then create favicon and OG card sizes from it. Report the list of output file paths. Verify that every file exists and that the set uses one palette. ``` ### Caveat Custom sizes must meet Codex limits, so for sizes such as a 1200x630 OG card the plugin generates a large master and resamples it locally.

Complete the install steps for the Codex CLI, `codex login`, and the plugin. 2. Make sure your working tree is clean so the changes land as a clear diff. 3. In Claude Code, ask: rename useSession to useAuthSession across the whole repo. 4. When Claude offers to delegate, agree so codex-implementer can edit the files. 5. Run `git diff` and review the changes before you commit. (inferred, check the README) ### Prompt to paste into your agent ```text In the Sateezg/codex-bridge plugin setup, use codex-implementer to rename to across . Report the list of changed files. Verify with a diff that only the intended identifiers changed before reporting success. ``` ### Caveat Only codex-implementer writes to your files, and only after you agree, so review the diff before committing.

Complete the install steps for the Codex CLI, `codex login`, and the plugin. 2. Open a terminal in the repo that has the branch you want reviewed. 3. Run `git diff main...HEAD | codex-run -C . --timeout 1200 -`. 4. Read the final answer, then ask a follow-up with `codex-run -C . -r "now show me the minimal patch"`. 5. Check each finding against the code before acting on it. ### Prompt to paste into your agent ```text In the Sateezg/codex-bridge plugin setup, pipe the diff of against main into codex-run with -C . and --timeout 1200, and report Codex's final answer. Verify that each finding names a real file and line in the repo before reporting it. ``` ### Caveat Codex runs in read-only mode by default, and a long review can take 10 or more minutes, so the example sets --timeout 1200.
