+    as of the date such litigation is filed.
+
+4.  Redistribution. You may reproduce and distribute copies of the
+    Work or Derivative Works thereof in any medium, with or without
+    modifications, and in Source or Object form, provided that You
+    meet the following conditions:

+    implied, including, without limitation, any warranties or conditions

+    PARTICULAR PURPOSE. You are solely responsible for determining the
+    appropriateness of using or redistributing the Work and assume any
+    risks associated with Your exercise of permissions under this License.

+    has been advised of the possibility of such damages.
+
+9.  Accepting Warranty or Additional Liability. While redistributing
+    the Work or Derivative Works thereof, You may choose to offer,
+    and charge a fee for, acceptance of support, warranty, indemnity,
+    or other liability obligations and/or rights consistent with this

+    incurred by, or claims asserted against, such Contributor by reason
+    of your accepting any such warranty or additional liability.

+
+## Quickstart
+
+Install globally:
+
+```shell
+npm install -g @openai/codex
+```
+
+Run interactively:
+
+```shell
+codex
+```
+
+Or, run with a prompt as input (and optionally in `Full Auto` mode):
+
+```shell
+codex "explain this codebase to me"
+```
+
+```shell
+codex --approval-mode full-auto "create the fanciest todo-list app"
+```
+
+That’s it – Codex will scaffold a file, run it inside a sandbox, install any
+missing dependencies, and show you the live result. Approve the changes and
+they’ll be committed to your working directory.
+
+---
+
+## Why Codex?
+
+Codex CLI is built for developers who already **live in the terminal** and want
+ChatGPT‑level reasoning **plus** the power to actually run code, manipulate
+files, and iterate – all under version control. In short, it’s _chat‑driven
+development_ that understands and executes your repo.
+
+- **Zero setup** — bring your OpenAI API key and it just works!
+- **Full auto-approval, while safe + secure** by running network-disabled and directory-sandboxed
+- **Multimodal** — pass in screenshots or diagrams to implement features ✨
+
+And it's **fully open-source** so you can see and contribute to how it develops!
+
+---
+
+## Security Model & Permissions
+
+Codex lets you decide _how much autonomy_ the agent receives and auto-approval policy via the
+`--approval-mode` flag (or the interactive onboarding prompt):
+
+| Mode                      | What the agent may do without asking            | Still requires approval                                         |
+| ------------------------- | ----------------------------------------------- | --------------------------------------------------------------- |
+| **Suggest** <br>(default) | • Read any file in the repo                     | • **All** file writes/patches <br>• **All** shell/Bash commands |
+| **Auto Edit**             | • Read **and** apply‑patch writes to files      | • **All** shell/Bash commands                                   |
+| **Full Auto**             | • Read/write files <br>• Execute shell commands | –                                                               |
+
+In **Full Auto** every command is run **network‑disabled** and confined to the
+current working directory (plus temporary files) for defense‑in‑depth. Codex
+will also show a warning/confirmation if you start in **auto‑edit** or
+**full‑auto** while the directory is _not_ tracked by Git, so you always have a
+safety net.
+
+Coming soon: you’ll be able to whitelist specific commands to auto‑execute with
+the network enabled, once we’re confident in additional safeguards.
+
+### Platform sandboxing details
+
+The hardening mechanism Codex uses depends on your OS:
+
+- **macOS 12+** – commands are wrapped with **Apple Seatbelt** (`sandbox-exec`).
+
+  - Everything is placed in a read‑only jail except for a small set of
+    writable roots (`$PWD`, `$TMPDIR`, `~/.codex`, etc.).
+  - Outbound network is _fully blocked_ by default – even if a child process
+    tries to `curl` somewhere it will fail.
+
+- **Linux** – we recommend using Docker for sandboxing, where Codex launches itself inside a **minimal
+  container image** and mounts your repo _read/write_ at the same path. A
+  custom `iptables`/`ipset` firewall script denies all egress except the
+  OpenAI API. This gives you deterministic, reproducible runs without needing
+  root on the host. You can read more in [`run_in_container.sh`](./codex-cli/scripts/run_in_container.sh)
+
+Both approaches are _transparent_ to everyday usage – you still run `codex` from your repo root and approve/reject steps as usual.
+
+---
+
+## System Requirements
+
+| Requirement                 | Details                                                         |
+| --------------------------- | --------------------------------------------------------------- |
+| Operating systems           | macOS 12+, Ubuntu 20.04+/Debian 10+, or Windows 11 **via WSL2** |
+| Node.js                     | **22 newer** (LTS recommended)                                  |
+| Git (optional, recommended) | 2.23+ for built‑in PR helpers                                   |
+| ripgrep (optional)          | `rg` accelerates large‑repo search                              |
+| RAM                         | 4‑GB minimum (8‑GB recommended)                                 |
+
+> Never run `sudo npm install -g`; fix npm permissions instead.
+
+---
+
+## CLI Reference
+
+| Command        | Purpose                             | Example                              |
+| -------------- | ----------------------------------- | ------------------------------------ |
+| `codex`        | Interactive REPL                    | `codex`                              |
+| `codex "…"`    | Initial prompt for interactive REPL | `codex "fix lint errors"`            |
+| `codex -q "…"` | Non‑interactive "quiet mode"        | `codex -p --json "explain utils.ts"` |
+
+Key flags: `--model/-m`, `--approval-mode/-a`, and `--quiet/-q`.
+
+---
+
+## Memory & Project Docs
+
+Codex merges Markdown instructions in this order:
+
+1. `~/.codex/instructions.md` – personal global guidance
+2. `codex.md` at repo root – shared project notes
+3. `codex.md` in cwd – sub‑package specifics
+
+Disable with `--no-project-doc` or `CODEX_DISABLE_PROJECT_DOC=1`.
+
+---
+
+## Non‑interactive / CI mode
+
+Run Codex head‑less in pipelines. Example GitHub Action step:
+
+```yaml
+- name: Update changelog via Codex
+  run: |
+    npm install -g @openai/codex
+    export OPENAI_API_KEY="${{ secrets.OPENAI_KEY }}"
+    codex -a auto-edit --quiet "update CHANGELOG for next release"
+```
+
+Set `CODEX_QUIET_MODE=1` to silence interactive UI noise.
+
+---
+
+## Recipes
+
+Below are a few bite‑size examples you can copy‑paste. Replace the text in quotes with your own task.
+
+| ✨  | What you type                                              | What happens                                                               |
+| --- | ---------------------------------------------------------- | -------------------------------------------------------------------------- |
+| 1   | `codex "Refactor the Dashboard component to React Hooks"`  | Codex rewrites the class component, runs `npm test`, and shows the diff.   |

+## Installation
+
+<details open>
+<summary><strong>From npm (Recommended)</strong></summary>
+
+```bash
+npm install -g @openai/codex
+# or
+yarn global add @openai/codex
+```
+
+</details>
+
+<details>
+<summary><strong>Build from source</strong></summary>
+
+```bash
+# Clone the repository and navigate to the CLI package
+git clone https://github.com/openai/codex.git
+cd codex/codex-cli
+
+# Install dependencies and build
+npm install
+npm run build
+
+# Run the locally‑built CLI directly
+node ./dist/cli.js --help
+
+# Or link the command globally for convenience
+npm link
+```
+
+</details>
+
+---
+
+## Configuration
+
+Codex looks for config files in **`~/.codex/`**.
+
+```yaml
+# ~/.codex/config.yaml
+model: o4-mini # Default model
+fullAutoErrorMode: ask-user # or ignore-and-continue
+```
+
+You can also define custom instructions:
+
+```yaml
+# ~/.codex/instructions.md
+- Always respond with emojis
+- Only use git commands if I explicitly mention you should
+```
+
+---
+
+## FAQ
+
+<details>
+<summary>How do I stop Codex from touching my repo?</summary>
+
+Codex always runs in a **sandbox first**. If a proposed command or file change looks suspicious you can simply answer **n** when prompted and nothing happens to your working tree.
+
+</details>
+
+<details>
+<summary>Does it work on Windows?</summary>
+
+Not directly, it requires [Linux on Windows (WSL2)](https://learn.microsoft.com/en-us/windows/wsl/install) – Codex is tested on macOS and Linux with Node ≥ 22.
+
+</details>
+
+<details>
+<summary>Which models are supported?</summary>
+
+Any model available with [Responses API](https://platform.openai.com/docs/api-reference/responses). The default is `o3`, but pass `--model gpt-4o` or set `model: gpt-4o` in your config file to override.

+## Contributing
+
+This project is under active development and the code will likely change pretty siginificantly. We'll update this message once that's complete!
+
+More broadly We welcome contributions – whether you are opening your very first pull request or you’re a seasoned maintainer. At the same time we care about reliability and long‑term maintainability, so the bar for merging code is intentionally **high**. The guidelines below spell out what “high‑quality” means in practice and should make the whole process transparent and friendly.
+
+### Development workflow
+
+- Create a _topic branch_ from `main` – e.g. `feat/interactive-prompt`.
+- Keep your changes focused. Multiple unrelated fixes should be opened as separate PRs.
+- Use `npm run test:watch` during development for super‑fast feedback.
+- We use **Vitest** for unit tests, **ESLint** + **Prettier** for style, and **TypeScript** for type‑checking.
+- Make sure all your commits are signed off with `git commit -s ...`, see [Developer Certificate of Origin (DCO)](#developer-certificate-of-origin-dco) for more details.
+
+```bash
+# Watch mode (tests rerun on change)
+npm run test:watch
+
+# Type‑check without emitting files
+npm run typecheck
+
+# Automatically fix lint + prettier issues
+npm run lint:fix
+npm run format:fix
+```
+
+### Writing high‑impact code changes
+
+1. **Start with an issue.**
+   Open a new one or comment on an existing discussion so we can agree on the solution before code is written.
+2. **Add or update tests.**
+   Every new feature or bug‑fix should come with test coverage that fails before your change and passes afterwards. 100 % coverage is not required, but aim for meaningful assertions.
+3. **Document behaviour.**
+   If your change affects user‑facing behaviour, update the README, inline help (`codex --help`), or relevant example projects.
+4. **Keep commits atomic.**
+   Each commit should compile and the tests should pass. This makes reviews and potential rollbacks easier.
+
+### Opening a pull request
+
+- Fill in the PR template (or include similar information) – **What? Why? How?**
+- Run **all** checks locally (`npm test && npm run lint && npm run typecheck`).
+  CI failures that could have been caught locally slow down the process.
+- Make sure your branch is up‑to‑date with `main` and that you have resolved merge conflicts.
+- Mark the PR as **Ready for review** only when you believe it is in a merge‑able state.
+
+### Review process
+
+1. One maintainer will be assigned as a primary reviewer.
+2. We may ask for changes – please do not take this personally. We value the work, we just also value consistency and long‑term maintainability.
+3. When there is consensus that the PR meets the bar, a maintainer will squash‑and‑merge.
+
+### Triaging labels
+
+- `good first issue` – great for newcomers, usually well‑scoped and low risk.
+- `help wanted` – higher impact, still looking for outside contributors.
+- `discussion` – exploring the problem/solution space; code contributions are discouraged until the direction is clear.
+
+### Community values
+
+- **Be kind and inclusive.** Treat others with respect; we follow the [Contributor Covenant](https://www.contributor-covenant.org/).
+- **Assume good intent.** Written communication is hard – err on the side of generosity.
+- **Teach & learn.** If you spot something confusing, open an issue or PR with improvements.
+
+### Getting help
+
+If you run into problems setting up the project, would like feedback on an idea, or just want to say _hi_ – please open a Discussion or jump into the relevant issue. We are happy to help.
+
+Together we can make Codex CLI an incredible tool. **Happy hacking!** :rocket:
+
+### Developer Certificate of Origin (DCO)
+
+All commits **must** include a `Signed‑off‑by:` footer.  
+This one‑line self‑certification tells us you wrote the code and can contribute it under the repo’s license.
+
+#### How to sign (recommended flow)
+
+```bash
+# squash your work into ONE signed commit
+git reset --soft origin/main          # stage all changes
+git commit -s -m "Your concise message"
+git push --force-with-lease           # updates the PR
+```
+
+> We enforce **squash‑and‑merge only**, so a single signed commit is enough for the whole PR.
+
+#### Quick fixes
+
+| Scenario          | Command                                                                                   |
+| ----------------- | ----------------------------------------------------------------------------------------- |
+| Amend last commit | `git commit --amend -s --no-edit && git push -f`                                          |
+| GitHub UI only    | Edit the commit message in the PR → add<br>`Signed-off-by: Your Name <email@example.com>` |
+
+The **DCO check** blocks merges until every commit in the PR carries the footer (with squash this is just the one).

+# Quick start examples
+
+This directory bundles some self‑contained examples using the Codex CLI. If you have never used the Codex CLI before, and want to see it complete a sample task, start with running **camerascii**. You'll see your webcam feed turned into animated ASCII art in a few minutes.
+
+If you want to get started using the Codex CLI directly, skip this and refer to the prompting guide.
+
+## Structure
+
+Each example contains the following:
+```
+example‑name/
+├── run.sh           # helper script that launches a new Codex session for the task
+├── task.yaml        # task spec containing a prompt passed to Codex
+├── template/        # (optional) starter files copied into each run
+└── runs/            # work directories created by run.sh
+```
+
+**run.sh**: a convenience wrapper that does three things:
+- Creates `runs/run_N`, where *N* is the number of a run.
+- Copies the contents of `template/` into that folder (if present).
+- Launches the Codex CLI with the description from `task.yaml`.
+
+**template/**: any existing files or markdown instructions you would like Codex to see before it starts working.
+
+**runs/**: the directories produced by `run.sh`.
+
+## Running an example
+
+1. **Run the helper script**:
+```
+cd camerascii
+./run.sh
+```
+2. **Interact with the Codex CLI**: the CLI will open with the prompt: “*Take a look at the screenshot details and implement a webpage that uses a webcam to style the video feed accordingly…*” Confirm the commands Codex CLI requests to generate `index.html`.
+
+3. **Check its work**: when Codex is done, open ``runs/run_1/index.html`` in a browser.  Your webcam feed should now be rendered as a cascade of ASCII glyphs. If the outcome isn't what you expect, try running it again, or adjust the task prompt.
+
+
+## Other examples
+Besides **camerascii**, you can experiment with:
+
+- **build‑codex‑demo**: recreate the original 2021 Codex YouTube demo.
+- **impossible‑pong**: where Codex creates more difficult levels.
+- **prompt‑analyzer**: make a data science app for clustering [prompts](https://github.com/f/awesome-chatgpt-prompts).

+description: |
+  I want you to reimplement the original OpenAI Codex demo.
+
+  Functionality:
+  - User types a prompt and hits enter to send
+  - The prompt is added to the conversation history
+  - The backend calls the OpenAI API with stream: true
+  - Tokens are streamed back and appended to the code viewer
+  - Syntax highlighting updates in real time
+  - When a full HTML file is received, it is rendered in a sandboxed iframe
+  - The iframe replaces the previous preview with the new HTML after the stream is complete (i.e. keep the old preview until a new stream is complete)
+  - Append each assistant and user message to preserve context across turns
+  - Errors are displayed to user gracefully
+  - Ensure there is a fixed layout is responsive and faithful to the screenshot design
+  - Be sure to parse the ouput from OpenAI call to strip the ```html tags code is returned within
+  - Use the system prompt shared in the API call below to ensure the AI only returns HTML
+
+  Support a simple local backend that can:
+  - Read local env for OPENAI_API_KEY
+  - Expose an endpoint that streams completions from OpenAI
+  - Backend should be a simple node.js app
+  - App should be easy to run locally for development and testing
+  - Minimal setup preferred — keep dependencies light unless justified
+
+  Description of layout and design:
+  - Two stacked panels, vertically aligned:
+    - Top Panel: Main interactive area with two main parts
+    - Left Side: Visual output canvas. Mostly blank space with a small image preview in the upper-left
+  - Right Side: Code display area
+    - Light background with code shown in a monospace font
+    - Comments in green; code aligns vertically like an IDE/snippet view
+  - Bottom Panel: Prompt/command bar
+    - A single-line text box with a placeholder prompt
+    - A green arrow (submit button) on the right side
+  - Scrolling should only be supported in the code editor and output canvas
+
+  Visual style
+  - Minimalist UI, light and clean
+  - Neutral white/gray background
+  - Subtle shadow or border around both panels, giving them card-like elevation
+  - Code section is color-coded, likely for syntax highlighting
+  - Interactive feel with the text input styled like a chat/message interface
+
+  Here's the latest OpenAI API and prompt to use:
+  ```
+  import OpenAI from "openai";
+
+  const openai = new OpenAI({
+    apiKey: process.env.OPENAI_API_KEY,
+  });
+
+  const response = await openai.responses.create({
+    model: "gpt-4.1",
+    input: [
+      {
+        "role": "system",
+        "content": [
+          {
+            "type": "input_text",
+            "text": "You are a coding agent that specializes in frontend code. Whenever you are prompted, return only the full HTML file."
+          }
+        ]
+      }
+    ],
+    text: {
+      "format": {
+        "type": "text"
+      }
+    },
+    reasoning: {},
+    tools: [],
+    temperature: 1,
+    top_p: 1
+  });
+
+  console.log(response.output_text);
+  ```
+  Additional things to note:
+  - Strip any html and tags from the OpenAI response before rendering
+  - Assume the OpenAI API model response always wraps HTML in markdown-style triple backticks like ```html <code> ```
+  - The display code window should have syntax highlighting and line numbers.
+  - Make sure to only display the code, not the backticks or ```html that wrap the code from the model.
+  - Do not inject raw markdown; only parse and insert pure HTML into the iframe
+  - Only the code viewer and output panel should scroll
+  - Keep the previous preview visible until the full new HTML has streamed in
+
+  Add a README.md with what you've implemented and how to run it.

+### Screenshot Description
+
+The image is a full–page screenshot of a single post on the social‑media site X (formerly Twitter).
+
+1. **Header row**
+   * At the very top‑left is a small circular avatar.  The photo shows the side profile of a person whose face is softly lit in bluish‑purple tones; only the head and part of the neck are visible.
+   * In the far upper‑right corner sit two standard X / Twitter interface icons: a circle containing a diagonal line (the “Mute / Block” indicator) and a three‑dot overflow menu.
+
+2. **Tweet body text**
+   * Below the header, in regular type, the author writes:
+
+     “Okay, OpenAI’s o3 is insane. Spent an hour messing with it and built an image‑to‑ASCII art converter, the exact tool I’ve always wanted. And it works so well”
+
+3. **Embedded media**
+   * The majority of the screenshot is occupied by an embedded 12‑second video of the converter UI.  The video window has rounded corners and a dark theme.
+   * **Left panel (tool controls)** – a slim vertical sidebar with the following labeled sections and blue–accented UI controls:
+     * Theme selector (“Dark” is chosen).
+     * A small checkbox labeled “Ignore White”.
+     * **Upload Image** button area that shows the chosen file name.
+     * **Image Processing** sliders:
+       * “ASCII Width” (value ≈ 143)
+       * “Brightness” (‑65)
+       * “Contrast” (58)
+       * “Blur (px)” (0.5)
+       * A square checkbox for “Invert Colors”.
+     * **Dithering** subsection with a checkbox (“Enable Dithering”) and a dropdown for the algorithm (value: “Noise”).
+     * **Character Set** dropdown (value: “Detailed (Default)”).
+     * **Display** slider labeled “Zoom (%)” (value ≈ 170) and a “Reset” button.
+
+   * **Main preview area (right side)** – a dark gray canvas that renders the selected image as white ASCII characters.  The preview clearly depicts a stylized **palm tree**: a skinny trunk rises from the bottom centre, and a crown of splayed fronds fills the upper right quadrant.
+   * A small black badge showing **“0:12”** overlays the bottom‑left corner of the media frame, indicating the video’s duration.
+   * In the top‑right area of the media window are two pill‑shaped buttons: a heart‑shaped “Save” button and a cog‑shaped “Settings” button.
+
+Overall, the screenshot shows the user excitedly announcing the success of their custom “Image to ASCII” converter created with OpenAI’s “o3”, accompanied by a short video demonstration of the tool converting a palm‑tree photo into ASCII art.

+  I have some existing work here (embedding prompts, clustering them, generating
+  summaries with GPT). I want to make it more interactive and reusable.
+
+  Objective: create an interactive cluster explorer
+     - Build a lightweight streamlit app UI
+     - Allow users to upload a CSV of prompts
+     - Display clustered prompts with auto-generated cluster names and summaries
+     - Click "cluster" and see progress stream in a small window (primarily for aesthetic reaons)
+     - Let users browse examples by cluster, view outliers, and inspect individual prompts
+     - See generated analysis rendered in the app, along with the plots displayed nicely
+     - Support selecting clustering algorithms (e.g. DBSCAN, KMeans, etc) and "recluster"
+     - Include token count + histogram of prompt lengths
+     - Add interactive filters in UI (e.g. filter by token length, keyword, or cluster)
+
+  When you're done, update the README.md with a changelog and instructions for how to run the app.

+# Prompt‑Clustering Utility
+
+This repository contains a small utility (`cluster_prompts.py`) that embeds a
+list of prompts with the OpenAI Embedding API, discovers natural groupings with
+unsupervised clustering, lets ChatGPT name & describe each cluster and finally
+produces a concise Markdown report plus a couple of diagnostic plots.
+
+The default input file (`prompts.csv`) ships with the repo so you can try the
+script immediately, but you can of course point it at your own file.
+
+---
+
+## 1. Setup
+
+1. Install the Python dependencies (preferably inside a virtual env):
+
+```bash
+pip install pandas numpy scikit-learn matplotlib openai
+```
+
+2. Export your OpenAI API key (**required**):
+
+```bash
+export OPENAI_API_KEY="sk‑..."
+```
+
+---
+
+## 2. Basic usage
+
+```bash
+# Minimal command – runs on prompts.csv and writes analysis.md + plots/
+python cluster_prompts.py
+```
+
+This will
+
+* create embeddings with the `text-embedding-3-small` model, 
+* pick a suitable number *k* via silhouette score (K‑Means),
+* ask `gpt‑4o‑mini` to label & describe each cluster,
+* store the results in `analysis.md`,
+* and save two plots to `plots/` (`cluster_sizes.png` and `tsne.png`).
+
+The script prints a short success message once done.
+
+---
+
+## 3. Command‑line options
+
+| flag | default | description |
+|------|---------|-------------|
+| `--csv` | `prompts.csv` | path to the input CSV (must contain a `prompt` column; an `act` column is used as context if present) |
+| `--cache` | _(none)_ | embed­ding cache path (JSON). Speeds up repeated runs – new texts are appended automatically. |
+| `--cluster-method` | `kmeans` | `kmeans` (with automatic *k*) or `dbscan` |
+| `--k-max` | `10` | upper bound for *k* when `kmeans` is selected |
+| `--dbscan-min-samples` | `3` | min samples parameter for DBSCAN |
+| `--embedding-model` | `text-embedding-3-small` | any OpenAI embedding model |
+| `--chat-model` | `gpt-4o-mini` | chat model used to generate cluster names / descriptions |
+| `--output-md` | `analysis.md` | where to write the Markdown report |
+| `--plots-dir` | `plots` | directory for generated PNGs |
+
+Example with customised options:
+
+```bash
+python cluster_prompts.py \
+  --csv my_prompts.csv \
+  --cache .cache/embeddings.json \
+  --cluster-method dbscan \
+  --embedding-model text-embedding-3-large \
+  --chat-model gpt-4o \
+  --output-md my_analysis.md \
+  --plots-dir my_plots
+```
+
+---
+
+## 4. Interpreting the output
+
+### analysis.md
+
+* Overview table: cluster label, generated name, member count and description.
+* Detailed section for every cluster with five representative example prompts.
+* Separate lists for
+  * **Noise / outliers** (label `‑1` when DBSCAN is used) and
+  * **Potentially ambiguous prompts** (only with K‑Means) – these are items that
+    lie almost equally close to two centroids and might belong to multiple
+    groups.
+
+### plots/cluster_sizes.png
+
+Quick bar‑chart visualisation of how many prompts ended up in each cluster.
+
+---
+
+## 5. Troubleshooting
+
+* **Rate‑limits / quota errors** – lower the number of prompts per run or switch
+  to a larger quota account.
+* **Authentication errors** – make sure `OPENAI_API_KEY` is exported in the
+  shell where you run the script.
+* **Inadequate clusters** – try the other clustering method, adjust `--k-max`
+  or tune DBSCAN parameters (`eps` range is inferred, `min_samples` exposed via
+  CLI).

+"""End‑to‑end pipeline for analysing a collection of text prompts.
+
+The script performs the following steps:
+
+1.  Read a CSV file that must contain a column named ``prompt``. If an
+    ``act`` column is present it is used purely for reporting purposes.
+2.  Create embeddings via the OpenAI API (``text-embedding-3-small`` by
+    default).  The user can optionally provide a JSON cache path so the
+    expensive embedding step is only executed for new / unseen texts.
+3.  Cluster the resulting vectors either with K‑Means (automatically picking
+    *k* through the silhouette score) or with DBSCAN.  Outliers are flagged
+    as cluster ``-1`` when DBSCAN is selected.
+4.  Ask a Chat Completion model (``gpt-4o-mini`` by default) to come up with a
+    short name and description for every cluster.
+5.  Write a human‑readable Markdown report (default: ``analysis.md``).
+6.  Generate a couple of diagnostic plots (cluster sizes and a t‑SNE scatter
+    plot) and store them in ``plots/``.
+
+The script is intentionally opinionated yet configurable via a handful of CLI
+options – run ``python cluster_prompts.py --help`` for details.

+# Prompting guide
+
+1. [Starter task](#starter-task)
+2. [Custom instructions](#custom-instructions)
+3. [Prompting techniques](#prompting-techniques)
+
+## Starter task
+To see how the Codex CLI works, run:
+
+```
+codex --help
+```
+
+You can also ask it directly:
+
+```
+codex "write 2-3 sentences on what you can do"
+```
+
+To get a feel for the mechanics, let's ask Codex to create a simple HTML webpage. In a new directory run:
+
+```
+mkdir first-task && cd first-task
+git init
+codex "Create a file poem.html that renders a poem about the nature of intelligence and programming by you, Codex. Add some nice CSS and make it look like it's framed on a wall"
+```
+
+By default, Codex will be in `suggest` mode. Select "Yes (y)" until it completes the task.
+
+You should see something like:
+
+```
+poem.html has been added.
+
+Highlights:
+- Centered “picture frame” on a warm wall‑colored background using flexbox.
+- Double‑border with drop‑shadow to suggest a wooden frame hanging on a wall.
+- Poem is pre‑wrapped and nicely typeset with Georgia/serif fonts, includes title and small signature.
+- Responsive tweaks keep the frame readable on small screens.
+
+Open poem.html in a browser and you’ll see the poem elegantly framed on the wall.
+```
+
+Enter "q" to exit out of the current session and `open poem.html`. You should see a webpage with a custom poem!
+
+## Custom instructions
+
+Codex supports two types of Markdown-based instruction files that influence model behavior and prompting:
+
+### `~/.codex/instructions.md`
+Global, user-level custom guidance injected into every session. You should keep this relatively short and concise. These instructions are applied to all Codex runs across all projects and are great for personal defaults, shell setup tips, safety constraints, or preferred tools.
+
+**Example:** "Before executing shell commands, create and activate a `.codex-venv` Python environment." or "Avoid running pytest until you've completed all your changes."
+
+### `CODEX.md`
+Project-specific instructions loaded from the current directory or Git root. Use this for repo-specific context, file structure, command policies, or project conventions. These are automatically detected unless `--no-project-doc` or `CODEX_DISABLE_PROJECT_DOC=1` is set.
+
+**Example:** “All React components live in `src/components/`".
+
+
+## Prompting techniques
+We recently published a [GPT 4.1 prompting guide](https://cookbook.openai.com/examples/gpt4-1_prompting_guide) which contains excellent intuitions for getting the most out of our latest models. It also contains content for how to build agentic workflows from scratch, which may be useful when customizing the Codex CLI for your needs. The Codex CLI is a reference implementation for agentic coding, and puts into practice many of the ideas in that document.
+
+There are three common prompting patterns when working with Codex. They roughly traverse task complexity and the level of agency you wish to provide to the Codex CLI.
+
+### Small requests
+For cases where you want Codex to make a minor code change, such as fixing a self-contained bug or adding a small feature, specificity is important. Try to identify the exact change in a way that another human could reflect on your task and verify if their work matches your requirements.
+
+**Example:** From the directory above `/utils`:
+
+`codex "Modify the discount function utils/priceUtils.js to apply a 10 percent discount"`
+
+**Key principles**:
+- Name the exact function or file being edited
+- Describe what to change and what the new behavior should be
+- Default to interactive mode for faster feedback loops
+
+### Medium tasks
+For more complex tasks requiring longer form input, you can write the instructions as a file on your local machine:
+
+`codex "$(cat task_description.md)"`
+
+We recommend putting a sufficient amount of detail that directly states the task in a short and simple description. Add any relevant context that you’d share with someone new to your codebase (if not already in `CODEX.md`). You can also include any files Codex should read for more context, edit or take inspiration from, along with any preferences for how Codex should verify its work.
+
+If Codex doesn’t get it right on the first try, give feedback to fix when you're in interactive mode!
+
+**Example**: content of `task_description.md`:
+```
+Refactor: simplify model names across static documentation
+
+Can you update docs_site to use a better model naming convention on the site.
+
+Read files like:
+- docs_site/content/models.md
+- docs_site/components/ModelCard.tsx
+- docs_site/utils/modelList.ts
+- docs_site/config/sidebar.ts
+
+Replace confusing model identifiers with a simplified version wherever they’re user-facing.
+
+Write what you changed or tried to do to final_output.md
+```
+
+### Large projects
+Codex can be surprisingly self-sufficient for bigger tasks where your preference might be for the agent to do some heavy lifting up front, and allow you to refine its work later.
+
+In such cases where you have a goal in mind but not the exact steps, you can structure your task to give Codex more autonomy to plan, execute and track its progress.
+
+For example:
+- Add a `.codex/` directory to your working directory. This can act as a shared workspace for you and the agent.
+- Seed your project directory with a high-level requirements document containing your goals and instructions for how you want it to behave as it executes.
+- Instruct it to update its plan as it progresses (i.e. "While you work on the project, create dated files such as `.codex/plan_2025-04-16.md` containing your planned milestones, and update these documents as you progress through the task. For significant pieces of completed work, update the `README.md` with a dated changelog of each functionality introduced and reference the relevant documentation.")
+
+*Note: `.codex/` in your working directory is not special-cased by the CLI like the custom instructions listed above. This is just one recommendation for managing shared-state with the model. Codex will treat this like any other directory in your project.*
+
+### Modes of interaction
+For each of these levels of complexity, you can control the degree of autonomy Codex has: let it run in full-auto and audit afterward, or stay in interactive mode and approve each milestone.
