Final codex-limits larger terminal dashboard Final codex-limits smaller terminal dashboard

The screenshots show the codex-limits terminal dashboards: clean, read-only TUIs that summarize Codex usage limits and reset-credit coupons in one place. The top section displays the usage windows currently supplied by Codex—weekly usage and, when available, the 5-hour window—with remaining percentages, visual progress bars, and reset times, while the lower section shows available reset coupons, their expiration dates, and the next coupon deadline.

Contents

Quick start

The package is available on npm as @simonesiega/codex-limits and supports Node.js 20 or newer.

Install codex-limits globally from npm:

npm install -g @simonesiega/codex-limits@latest

The @latest tag ensures you install the latest published version.

Then run it from any terminal:

codex-limits

The list of available commands is shown when you run codex-limits --help or in the Usage section.

Install an optional agent integration by name:

codex-limits agents install <agent-name>

For example, install the OpenCode, pi, or GitHub Copilot CLI integration:

codex-limits agents install opencode
codex-limits agents install pi
codex-limits agents install copilot

The existing codex-limits init --<agent-name> syntax remains supported as a compatibility command.

Requirements

Requirement Details
Node.js Node.js 20 or newer is required to run the published CLI. Bun is only required for local development.
Codex For normal use, Codex should already be installed and authenticated so codex-limits can discover its local data and credentials. Advanced setups can provide supported environment overrides instead.
Operating systems Windows, macOS, and Linux are supported through their standard Codex data locations. Use CODEX_LIMITS_HOME or CODEX_HOME if your data is stored elsewhere.
Internet connection Local usage fallback can work offline. An internet connection is required for current live usage and reset-credit coupon information; unavailable network data is reported safely without breaking the dashboard.

The standalone CLI supports Node.js 20 and newer. The optional pi integration runs inside the pi host; pi 0.81.x requires Node.js 22.19 or newer. The GitHub Copilot CLI integration uses Copilot's experimental extension host and its CLI-provided SDK.

Overview

When you are working with Codex or agent-based coding tools, usage limits can interrupt your flow if you do not know what is left or when the next reset happens.

codex-limits gives you that information in one clean terminal view. It shows the usage windows currently supplied by Codex, including weekly usage and the 5-hour window when available, together with remaining percentages, progress bars, reset times, and reset-credit coupons, so you can quickly check your status and continue coding without leaving the terminal.

It also includes plain-text commands for quick checks, an explicitly confirmed codex-limits reset action for using one reset coupon, a safe codex-limits doctor diagnostic report, JSON output for scripts and automation, optional agent integrations through codex-limits agents, and safe output that never prints tokens, account IDs, auth headers, cookies, private paths, or raw local files.

Agent integrations

Optional integrations make Codex limit information available directly inside supported coding agents while reusing the same normalized read paths and safety model as the CLI. Agent integrations do not receive the reset command's mutation capability.

For installation details, adapter behavior, architecture, and contribution guidance, see the detailed Agent integrations guide.

Supported agents

Agent Status Agent command Guide Description
OpenCode Supported /codex-limits Installation and usage Opens a fast, read-only Codex limits dashboard directly inside OpenCode without sending the request to the LLM.
pi Supported /codex-limits Installation and usage Opens a themed, read-only Codex limits overlay directly inside pi without sending the request to the LLM.
GitHub Copilot CLI Supported /codex-limits Installation and usage Logs a compact, read-only Codex limits summary through a local Copilot CLI extension without sending it to the LLM.

Agent integrations are not enabled automatically during package installation. They must be installed with codex-limits agents install (or the compatible codex-limits init syntax) and are only available in the agent terminal after a restart. See Adding new agents if you want to add support for another agent.

Selected agent integration screenshots

OpenCode

The OpenCode integration adds a /codex-limits command that opens a compact modal inside the agent interface. It gives a quick read-only summary of the available usage windows and reset-credit coupons, then lets you close the view and return immediately to the conversation.

pi

The pi integration adds a /codex-limits command that opens a themed overlay inside the agent interface. It shows the same read-only usage windows and reset-credit summary without sending the request or limit data to the LLM.

GitHub Copilot CLI

The GitHub Copilot CLI integration adds a /codex-limits command that displays a compact, read-only limits summary in the session timeline. It loads the shared core locally without sending the request or limit data to the LLM.

Adding new agents

New agents use the same four-file adapter layout under src/agents/<agent-name>: format.ts, install.ts, integration.ts, and plugin.ts. The integration descriptor owns its metadata, environment help, installer, and read-only diagnostic check; registering that descriptor in src/agents/index.ts automatically connects shared installation, compatibility help, and doctor diagnostics. Every registered agent must also use a matching src/package/<agent-name>.ts host wrapper and expose @simonesiega/codex-limits/<agent-name> through the shared package-entry build. Each integration should show Codex limit information quickly and safely without exposing tokens, account IDs, cookies, auth headers, or raw local files.

See the Contributing guide if you want to add support for another agent.

How it works

codex-limits is built around a shared core with different output surfaces on top of it.

Area Path Purpose
CLI entry src/package/cli.ts Starts the codex-limits command and delegates to the shared command registry.
Agent host entries src/package/<agent-name>.ts Publish narrow, agent-specific host contracts through one shared package-entry build.
Core logic src/package/core Detects Codex data, normalizes live and local information, performs confirmed coupon redemption, and keeps sensitive values out of output.
CLI commands src/package/commands Defines command metadata, shared parsing and help, scoped runtime services, and focused command handlers.
Terminal UI src/package/tui Renders the clean Ink-based dashboard from normalized usage data.
Agent integrations src/agents Contains optional coding-agent adapters used by the codex-limits agents command group.
Tests tests Contains the test suite used to validate core behavior, CLI output, safety rules, and integration logic.

This structure keeps the project easy to extend: the core owns data meaning and authenticated network operations, while commands control when capabilities are used and the TUI and agents remain rendering-only surfaces.

Supported package interfaces

For general use and automation, the supported interfaces are the codex-limits CLI and its documented JSON output. The package does not currently expose a general-purpose JavaScript API.

The npm module exports are reserved for supported agent hosts:

Module specifier Purpose
@simonesiega/codex-limits OpenCode plugin entry point retained at the package root for plugin-loader compatibility.
@simonesiega/codex-limits/opencode Explicit alias for the same OpenCode plugin module.
@simonesiega/codex-limits/pi Host-only entry point for the bundled pi extension.
@simonesiega/codex-limits/copilot Host-only entry point for the bundled GitHub Copilot CLI extension.

There is intentionally no @simonesiega/codex-limits/core export. Files under src/package/core are shared implementation details and are not covered by the package's public compatibility contract. The presence of an agent module export does not install or enable that integration; use codex-limits agents install <agent-name> for setup.

Environment

codex-limits works out of the box when it can find the required Codex data automatically. By default, it tries to detect the local Codex data directory and discover the information needed to show usage limits and reset-credit coupons. Most users do not need to configure anything manually.

Environment variables are only used as a fallback when automatic discovery is not enough, or when you want to override the default behavior.

Variable Purpose
CODEX_LIMITS_HOME Overrides the local Codex data directory before all other candidates.
CODEX_HOME Uses Codex's native home override when CODEX_LIMITS_HOME is not set.
CODEX_LIMITS_ACCESS_TOKEN Provides an access token for authenticated live usage and reset-credit requests.
CODEX_LIMITS_ACCOUNT_ID Provides the account ID paired with CODEX_LIMITS_ACCESS_TOKEN.
CODEX_LIMITS_USAGE_ENDPOINT Overrides the live usage endpoint with HTTPS or loopback HTTP for advanced setups/tests.
CODEX_LIMITS_SKIP_INIT Suppresses optional global-install setup guidance from the non-interactive postinstall.
PI_CODING_AGENT_DIR Overrides pi's global agent configuration directory for integration setup and checks.
COPILOT_HOME Overrides GitHub Copilot CLI's user configuration and extension directory.

Data access and safety

Local Codex data is always inspected read-only with bounded file, directory, JSONL, and response limits. Credentials, raw files, and private paths are excluded from public output. Live requests require HTTPS, except for loopback HTTP during local testing. Only codex-limits reset mutates the remote account, and it requires an interactive recap followed by an explicit y or yes confirmation. See SECURITY.md for the complete data-access and network-safety model.

Usage

Command Description
codex-limits Opens the interactive terminal dashboard.
codex-limits status Prints a plain usage summary.
codex-limits coupons Prints reset-credit coupon information.
codex-limits coupons --json Prints machine-readable reset-credit coupon data only.
codex-limits reset <coupon-index> Reviews and uses the numbered available reset coupon.
codex-limits reset --soonest Reviews and uses the coupon that expires first.
codex-limits --json Prints machine-readable usage and coupon data.
codex-limits doctor Prints safe environment and connectivity diagnostics.
codex-limits doctor --json Prints machine-readable diagnostics only.
codex-limits agents Lists the available agent-management subcommands.
codex-limits agents install <agent...> Installs one or more named agent integrations.
codex-limits agents install --all Installs every supported agent integration.
codex-limits init Runs the compatible interactive installation flow.

Resetting usage

Use one available reset coupon by the number shown in codex-limits coupons, or let the command select the available coupon that expires first:

codex-limits reset <coupon-index>
codex-limits reset --soonest

Reset is an irreversible remote mutation and works only in an interactive terminal. The command refreshes the coupon list, rejects missing or unavailable indexes, prints a recap with the selected coupon and expiration, and asks Type y to confirm [y/N]. Only y or yes sends the consume request; every other answer cancels without using a coupon. The request carries the coupon's internal service ID and a fresh idempotency key so an internal retry cannot consume a second coupon.

If no coupon is available, the command reports that nothing was used. If the selected index is absent, coupon details cannot be verified, or the final service result is ambiguous, it exits without claiming success.

Diagnostics

Run the read-only doctor command when Codex data, live usage, or an agent integration is unavailable:

codex-limits doctor
Codex Limits diagnostics

Package version:                1.0.0
Node.js version:                22.0.0
Operating system:               Windows
Codex home detected:            Yes
Authentication found:           Yes
Local usage found:              Yes
Live endpoint:                  Reachable
OpenCode integration:           Installed
pi integration:                 Installed
GitHub Copilot CLI integration: Installed

No sensitive values were displayed.

The doctor checks only whether recognized resources are available, including the OpenCode, pi, and GitHub Copilot CLI integrations. It never prints credential values, private paths, endpoint URLs, configuration contents, or raw Codex data. The live check makes the same bounded authenticated read-only usage request as the dashboard; it is reported as Not checked when complete authentication is unavailable. Use codex-limits doctor --json for the stable machine-readable form documented in JSON output.

Agent management

Use codex-limits agents install to install optional integrations. Installation only updates the selected agent configuration; it does not send a prompt to an LLM or modify Codex data.

Command What it does
codex-limits agents Prints help for the agent-management command group.
codex-limits agents install Prompts for every supported integration when stdin and stdout are interactive terminals. If no integration is selected, nothing is installed.
codex-limits agents install <agent...> Installs one or more named supported integrations without prompting.
codex-limits agents install --all Installs every supported integration without prompting.
codex-limits agents install --help or -h Prints generated installation help without changing any configuration.
codex-limits init --<agent-name> or codex-limits init --all Preserves the existing initialization syntax as a compatibility command.

--all cannot be combined with agent names. Duplicate and unknown agent names, unknown options, and extra positional arguments are rejected before any integration is installed. In a non-interactive terminal, provide --all or at least one agent name.

Troubleshooting

No Codex data found

Make sure Codex has been run and authenticated at least once. If its data is stored outside the standard location, set CODEX_LIMITS_HOME or CODEX_HOME to the Codex data directory, then run codex-limits status again.

Usage information unavailable

Run codex-limits doctor to check Codex home discovery, authentication presence, local usage, and live endpoint reachability without exposing sensitive values. Run codex-limits status to view the safe warning summary. Confirm that Codex authentication is current and that the machine can reach the ChatGPT Codex service. Local session data may still provide a fallback when live usage is unavailable; coupon information requires an internet connection.

Permission errors

Confirm that your user can read the selected Codex directory and its session files. Do not run the CLI with elevated privileges unless your Codex installation explicitly requires it. Prefer correcting the directory permissions or selecting the correct directory with CODEX_LIMITS_HOME.

Agent command not appearing after installation

Run the named installer again, for example codex-limits agents install opencode, codex-limits agents install pi, or codex-limits agents install copilot, and confirm that it reports the integration as installed or already installed. Restart the target agent terminal so it reloads its configuration. If the command is still missing, verify that the displayed configuration paths belong to the agent installation you are using.
