A local-first issue board that runs in a browser and can be embedded in Codex through the standalone CDP launcher or its injection script. The same HTTP API powers the React UI and the taskctl CLI used by the bundled Codex Skill.
- Node.js 22.5 or newer
Download the repository ZIP from GitHub, or clone it with Git:
git clone https://github.com/acc-c/codex-taskboard.git
cd codex-taskboardnpm install
npm run build
npm startOpen http://127.0.0.1:47823. The SQLite database is stored at .data/taskboard.sqlite.
For development with live frontend reload:
npm run devThe Vite UI runs at http://127.0.0.1:5173 and proxies API requests to the local service.
Run it from the project:
npm run taskctl -- project create \
--id my-project \
--name "My project" \
--workspace-path /absolute/path/to/repository
npm run taskctl -- issue create \
--project my-project \
--title "Implement the next slice" \
--status todo \
--priority high \
--labels product,mvpUse npm link if you want taskctl on your shell path. Set CODEX_TASKBOARD_URL to point the CLI at another local or LAN service. Cloud deployments are configured through the loopback companion with taskctl cloud login.
Copy or symlink skills/manage-taskboard into the Codex skills directory, then start a new Codex task:
ln -s /absolute/path/to/codex-taskboard/skills/manage-taskboard \
~/.codex/skills/manage-taskboardThe Skill teaches Codex to inspect an issue, move it to in_progress, use optimistic versions, verify the work, and then move it to in_review; it moves the issue to done only after the user explicitly confirms acceptance or asks to mark it complete.
Keep the existing Codex window open. From the Taskboard repository, start a second Codex instance with a dedicated CDP port:
open -n -a /Applications/ChatGPT.app --args \
--remote-debugging-port=9231 \
--remote-allow-origins=http://127.0.0.1:9231After the new Codex window appears, run the injector in another terminal:
CODEX_TASKBOARD_HOST=127.0.0.1 \
npm run codex:inject -- --port 9231 --openKeep the injector terminal running while using the embedded panel. The original Codex window remains unchanged, and the new window receives the Taskboard sidebar entry. If port 9231 is occupied, use another port in both commands.
Quit every running Codex window, then run:
CODEX_TASKBOARD_HOST=127.0.0.1 npm run codexThis starts the local Taskboard service when needed, launches the official macOS Codex app with a loopback-only CDP port, injects a native-looking Taskboard entry after Plugins, and keeps watching both the service and replacement renderers. Opening Taskboard asks this launcher to health-check the fixed local service, restart it when needed, and rebuild a failed iframe. Keep this command running while using the embedded panel. The launcher does not modify ChatGPT.app or its app.asar.
Codex 26.715.52143 ships a renderer CSP that blocks arbitrary HTTP iframes. The launcher therefore enables CDP CSP bypass, reloads that renderer once, installs the document-start script, and waits until the Taskboard OOPIF is actually loaded. CDP is unauthenticated to other processes on the same machine, so only run trusted local code while the launcher is active.
To inject into a Codex instance that was already launched with CDP by another method, run:
npm run codex:inject -- --port 9229 --openThis command also stays resident so the injected tab can restart Taskboard after a service exit. Stop it with Ctrl-C.
The script adds a Taskboard entry to the Codex sidebar and renders the iframe across Codex's complete main workspace, including the contextual titlebar area so Taskboard's own header does not leave an empty strip. That full rectangular header is placed above Electron's draggable layer and marked no-drag; because the native contextual actions are suppressed while Taskboard is active, its own actions use their normal edge padding without an artificial right-side gap. The native sidebar stays mounted, while the previous page selection and contextual header are temporarily suppressed; choosing another Codex page restores them.
The "Open in conversation" action selects the corresponding native Codex project when one is available and opens an unsent native composer with $manage-taskboard ISSUE-ID. A conversation is attributed only after it actually processes the issue: taskctl reads Codex's CODEX_THREAD_ID and records that ID on the issue or comment mutation. Recorded IDs are clickable through Codex's native route bridge. Each issue can bind either one Git branch or one worktree; the options are scanned from the selected Codex project's repository instead of being typed by hand. The integration uses Codex's existing project, composer, and route markers; it does not patch React, replace fetch, load private chunks, or edit Codex data files.
To use a different UI origin, set window.__CODEX_TASKBOARD_URL__ before the user script runs.
| Variable | Default | Purpose |

CODEX_TASKBOARD_HOST |
0.0.0.0 |
HTTP bind address; use 127.0.0.1 to disable LAN access |
CODEX_TASKBOARD_PORT |

Local HTTP port |
CODEX_TASKBOARD_DATA_DIR |
.data |
SQLite data directory |
CODEX_TASKBOARD_URL |
http://127.0.0.1:47823 |
CLI API origin |
npm start prints both the local URL and the available LAN URLs. Teammates on the same trusted network can open one of those LAN URLs and use the same taskboard service. Task, comment, and attachment changes are broadcast to every open client through server-sent events; reconnecting clients perform a full refresh so changes made while disconnected are not missed. A teammate using taskctl can point it at the shared service with CODEX_TASKBOARD_URL=http://<host-ip>:47823.
LAN mode has no account authentication: anyone on the trusted local network who can reach the URL can read and write the taskboard. Public internet and cloud deployment require an authenticated deployment boundary.
For two trusted collaborators, the taskboard can run on Cloudflare with Worker Static Assets and API routes, D1 as the authoritative business database, and a private R2 bucket for attachments. The deployment uses HTTPS Basic Authentication with a shared password and refreshes open boards after a global revision changes.
Each device keeps its own project checkout mapping and continues to use a local companion for Codex, Git/worktree, Skill, and MCP capabilities. Cloud mode never falls back to or double-writes the local SQLite database.
See Cloud collaboration for owner deployment, existing GitHub installation setup, password rotation, local path mapping, and the one-time local-data migration flow.
npm run checkThis runs TypeScript checking, a production frontend build, and the server/CLI/injection test suite.
