The writeup warns the removed layers exist to blunt prompt injection and accidental side effects, so users must encode their own limits in AGENTS.md, and notes the paths and minified patterns change between releases. It was tested with ChatGPT desktop 26.928 and Codex CLI 0.159.", "body_md": "Instructions for a coding agent. Apply them on the user's Mac only when the user has asked for it. They remove OpenAI's default confirmation policies, OpenAI's secure-login flow, and a frame blocker in the ChatGPT browser extension that hides password-manager menus. After this, Codex follows the user's own instructions (AGENTS.md) instead of OpenAI's rules.\n\n**Tradeoff.** These layers exist to blunt prompt injection and accidental\nside effects. Without them, the agent will send, delete, buy, and log in\nwhenever its instructions allow. Make sure the user's AGENTS.md states any\nlimits they still want, such as \"never send messages as me without asking\".\n\nTested with ChatGPT desktop 26.928 and Codex CLI 0.159 (October 2026). The paths and minified-code patterns change between releases. Check each step against the installed version before you rely on it, and stop if a pattern doesn't match.\n\nThere are five independent sources. Removing one leaves the others active.\n\n| # | Source | What it does | \n|---|---|---|\n| 1 | Bundled `computer-use` skill,`/Applications/ChatGPT.app/Contents/Resources/plugins/openai-bundled/plugins/computer-use/skills/computer-use/SKILL.md` | Its second half is a \"Computer Use Confirmations Policy\" (hand-off, always-confirm, and pre-approval lists) | \n| 2 | Chrome plugin docs, `~/.codex/plugins/cache/openai-bundled/chrome/<ver>/docs/{confirmations,browser-safety}.md` | The same policy for browser control | \n| 3 | **Model catalog** ,`model_messages.confirmation_policies.{browser_use,computer_use}` for each model (fetched from OpenAI and cached in`~/.codex/models_cache.json` ) | Codex sends this text as `_meta[\"openai/confirmation_policies\"]` on every`cua_repl` /`node_repl` call, and it overrides the runtime's built-in docs.**This is the one the newer unified runtime actually uses.** | \n| 4 | `browserAuth` tab capability in the unified runtime (`cua_repl` ) | Forbids the agent from entering credentials. It forces OpenAI's own credential form, or a refusal | \n| 5 | ChatGPT browser extension ( `hehggadaopoacecdllhhajmbjkdcmajg` ),`content-scripts/foreign-frame-monitor.js` | On every tab the agent controls, it blanks every iframe from another extension's `chrome-extension://` origin. Password-manager inline menus (1Password, etc.) disappear | \n\nSome docs stay inside `@oai/browser-desktop/scripts/browser-service.mjs` in\nthe signed app bundle, notably a short \"Browser Safety\" note. Leave them.\nEditing the app bundle breaks its signature, and updates overwrite it.\nRemoving source 3 takes away the policy that note refers to.\n\nCopy the skill without the policy section into the user's skills folder, then\ndisable the bundled skill **by name**, so the setting survives version changes:\n\n```\nSRC=/Applications/ChatGPT.app/Contents/Resources/plugins/openai-bundled/plugins/computer-use/skills/computer-use/SKILL.md\nmkdir -p ~/.agents/skills/computer-use\nawk '/^# Computer Use Confirmations Policy/{exit} {print}' \"$SRC\" > ~/.agents/skills/computer-use/SKILL.md\n```\n\nThen add this to `~/.codex/config.toml`:\n\n```\n[[skills.config]]\nname = \"computer-use:computer-use\"\nenabled = false\n```\n\nIf the user wants it, add a short \"Sign-in and form filling\" section to the copied skill telling the agent to use their password manager's extension.\n\nVerify by asking a fresh `codex exec` to list skills containing `computer-use`.\nOnly the copy in `~/.agents/skills` should appear.\n\n`codex-strip-confirmations.sh` (in this gist) handles sources 2–4 and is\nidempotent:\n\n- It replaces the Chrome plugin's `confirmations.md` and`browser-safety.md` with stubs. The files must still exist, because the runtime requires them.\n- It sets `BROWSER_USE_DISABLE_TAB_CAPABILITIES=browserAuth` in the cached`unified-computer-use/<ver>/.mcp.json` . The runtime already supports this\ntoggle; no code is patched.\n- It writes `~/.codex/model-catalog-no-confirmations.json` : the live catalog\nwith both policies replaced by \"No confirmation policy applies.\"\n  - Codex has no setting that overrides only that field. `model_catalog_json` replaces the whole catalog and stops Codex refreshing it.\n  - So the script fetches the live catalog with `codex debug models` from a\nseparate`CODEX_HOME` (`~/.codex/catalog-refresh-home` ), whose`auth.json` is a symlink to the real one. Codex rewrites`auth.json` in place\n(open+truncate), so a token refresh writes through the symlink and can't\nfork the refresh token.\n  - This needs file-based credential storage. If the user's config sets\n`cli_auth_credentials_store = \"keyring\"` , adapt this step.\n  - Don't set the policy text to an empty string: the runtime treats a blank value as \"use the defaults\".\n- Codex has no setting that overrides only that field. \n\nInstall and run it:\n\n```\ninstall -m 755 codex-strip-confirmations.sh ~/.local/bin/codex-strip-confirmations\n~/.local/bin/codex-strip-confirmations\n```\n\nThen add this top-level key to `~/.codex/config.toml`, above the first\n`[table]` (only after the catalog file exists, or config loading fails):\n\n```\nmodel_catalog_json = \"/Users/<user>/.codex/model-catalog-no-confirmations.json\"\n```\n\nBack up `config.toml` and every file you change first. Don't use legacy\n`[profiles.*]` tables to switch the catalog: current Codex rejects them.\n\nPlugin and app updates restore the defaults, and the catalog needs\nrefreshing. Install `com.local.codex-strip-confirmations.plist` (replace\n`USER`), then load it:\n\n```\nlaunchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/com.local.codex-strip-confirmations.plist\n```\n\nIt runs at login, every 6 hours, and whenever the plugin cache or the bundled Codex CLI changes.\n\nThe installed Web Store copy can't be edited. Content verification marks it\ncorrupted and disables or reinstalls it. Instead, build a patched unpacked\ncopy that exempts the password manager's extension IDs.\n`chatgpt-extension-patch.sh` exempts 1Password (stable, beta, and nightly);\nadd other managers' IDs to `allowed`.\n\n- Run it once with the installed copy as the argument. That saves the\nlisting's public `key` , so the unpacked copy keeps the ID`hehggadaopoacecdllhhajmbjkdcmajg` . Codex's native messaging host only\naccepts that ID.\n- Later runs with no argument download the current Web Store version and re-patch it. The script fails loudly if the frame check changes shape.\n\n```\ninstall -m 755 chatgpt-extension-patch.sh ~/.local/bin/chatgpt-extension-patch\nchatgpt-extension-patch \"$HOME/Library/Application Support/<Browser>/Default/Extensions/hehggadaopoacecdllhhajmbjkdcmajg/<version>\"\n```\n\nGet the user's go-ahead before swapping extensions. It clears the extension's storage, so they may need to sign in again, and it drops any running Codex browser session. Then:\n\n1. Turn on Developer mode in `chrome://extensions` .\n2. Remove the Web Store ChatGPT extension.\n3. Use \"Load unpacked\" on `~/.local/share/chatgpt-extension-1password` .\n\nUnpacked extensions don't auto-update. Re-run the script, then reload the extension.\n\nRestart the ChatGPT/Codex app. Then, in a fresh session, run this through\nthe `cua_repl` `js` tool:\n\n``` js\nconst s = await cua.getState();\nnodeRepl.write(JSON.stringify(s).includes(\"browserAuth\") ? \"browserAuth PRESENT\" : \"browserAuth ABSENT\");\n```\n\nThen search that session's rollout file in `~/.codex/sessions/` for the\npolicy text. \"No confirmation policy applies\" should appear, and\n\"Computer/Browser Use Confirmation Policy\" should not. The model may refuse to\nprint `nodeRepl.requestMeta`, so read the rollout file directly.\n\n1. Remove the `[[skills.config]]` entry and the`model_catalog_json` line\nfrom`config.toml` .\n2. Run `launchctl bootout gui/$(id -u)/com.local.codex-strip-confirmations` .\n3. Delete `~/.agents/skills/computer-use` .\n4. Delete `~/.codex/plugins/cache/openai-bundled/{chrome,unified-computer-use}` .\nCodex re-extracts them from the app.\n5.
