Codex Channels

codex-channels

codex-channels is a local-first interaction runtime for Codex. It is designed for the missing layer between Codex as the primary agent and external runtimes or MCP servers that need to request approvals, permissions, user input, or elicitation.

Most current Codex integrations treat Codex as a worker, an MCP server, or a remote backend. codex-channels is aimed at the opposite direction: keeping Codex in the driver's seat while routing interactive requests through pluggable channels such as a local runtime, Slack, Discord, or Telegram.

At a glance

• What it is: a Codex-first interaction runtime for approvals, permissions, user input, and elicitation
• Default path: local-first, single-machine, no SaaS required
• Main surfaces: npm packages + CLI, with an optional Codex plugin wrapper
• Current best use case: give an external runtime or bridge a reusable way to ask the human something while Codex stays the main agent
• Status: early, but the local runtime / CLI / Codex bridge path are all usable now

Most important use case

The most important way to think about codex-channels is:

> use it from inside Codex, not just as a standalone local server

The standalone CLI is useful for trying the runtime, debugging it, or integrating a third-party tool. But the higher-value path is:

1. install codex-channels
2. register the local plugin / MCP wrapper with Codex
3. let Codex surface approvals, user input, or other interaction flows

through the codex-channels runtime

If you only remember one thing, remember that codex-channels is meant to make Codex-side human interaction easier.

Quickstart

Install from npm

npm install -g @cafitac/codex-channels
codex-channels plugin-bootstrap

This now installs a Codex-visible codex-channels skill set into the canonical Codex skill root (including shortcut skills such as operator-status, next-step, channels-watch, and channels-follow) as well as generating the plugin wrapper and MCP surface. Then restart Codex so it can reload both surfaces.

If you run plugin-bootstrap in an interactive shell, it now uses an arrow-key menu so you can choose between user-level and workspace-local installation with Enter. For most global installs, user-level is the recommended default.

Try it inside Codex first

After bootstrap, Codex should be able to discover the codex-channels plugin/skill surface.

If you want to confirm the runtime manually first, run:

codex-channels operator-status
codex-channels watch
codex-channels next-step
codex-channels doctor
codex-channels pending
codex-channels demo

demo intentionally waits for a real reply so you can see the full publish → inspect → reply → resolve loop.

Keep the CLI updated

On the default interactive help screen, the CLI can check for a newer published npm version and show an arrow-key menu:

• Update now
• Skip
• Skip until next version

You can also trigger the updater directly:

codex-channels self-update

If the CLI is running from a source checkout instead of a published npm install, self-update prints the shortest manual update steps instead of trying to mutate the checkout automatically.

Inspect and reply to interactions

codex-channels pending
codex-channels inspect
codex-channels reply-latest --text staging
# or codex-channels reply --id  --text staging

Typical flow:

1. run codex-channels demo
2. in another terminal, run codex-channels pending
3. reply with codex-channels reply-latest --text staging
4. if needed, fall back to codex-channels inspect + reply --id ...
5. watch the original demo command finish with the resolved response

Example:

# terminal 1
codex-channels demo

# terminal 2
codex-channels inspect --state-file .codex-channels/state.json
codex-channels reply --id demo-1234567890 --text staging --port 4317

demo waiting after it prints the interaction id is expected behavior. It only finishes after you send a real reply from another terminal.

Lower-level runtime / bridge commands

codex-channels serve --port 4317 --state-file .codex-channels/state.json
codex-channels status --port 4317
codex-channels submit \
  --port 4317 \
  --state-file .codex-channels/state.json \
  --interaction-file ./interaction.json
codex-channels bridge-stdio --port 4317 --state-file .codex-channels/state.json

Why this exists

Codex already exposes low-level interaction primitives through the app-server protocol, including approvals, permissions requests, user input, and MCP elicitation. What is still missing is a reusable runtime that:

1. receives those interaction requests,
2. persists and routes them,
3. exposes them through a local or remote channel, and
4. returns the user's decision back into the Codex-native flow.

That runtime is the purpose of codex-channels.

Design goals

• Codex-first: Codex remains the main agent.
• Local-first: the default path works on a single machine with no SaaS dependency.
• Channel-pluggable: local, Slack, Discord, Telegram, and future backends share one model.
• MCP-generic: not tied to a single MCP server or agent runtime.
• OSS-friendly: packageable as npm modules, with reusable contracts and adapters.

Install paths

• npm first: main distribution path for local runtime usage and external consumers
• Codex plugin wrapper: optional convenience layer for Codex discovery via .codex-plugin/ + .mcp.json

If you are just trying it

• doctor tells you whether the local runtime is already reachable and what command to try next
• demo starts a sample interaction and waits for you to answer it from another terminal
• inspect shows what interactions currently exist in the local state file
• reply sends an answer back to a running local runtime

If you want to use it from inside Codex

After:

codex-channels plugin-bootstrap

restart Codex.

Then inside Codex, treat codex-channels as the interaction layer that the plugin/bridge can use for:

• approval requests
• free-text user input
• inspect/reply style debugging flows

If you are testing by hand, the easiest companion commands are still:

codex-channels doctor
codex-channels demo
codex-channels inspect
codex-channels reply --id  --text staging

CLI

codex-channels doctor
codex-channels self-update
codex-channels demo
codex-channels inspect
codex-channels reply --id  --text staging
npx @cafitac/codex-channels serve --port 4317 --state-file .codex-channels/state.json
npx @cafitac/codex-channels status --port 4317
npx @cafitac/codex-channels submit --port 4317 --state-file .codex-channels/state.json --interaction-file ./interaction.json
npx @cafitac/codex-channels bridge-stdio --port 4317 --state-file .codex-channels/state.json
npx @cafitac/codex-channels bridge-spawn --port 4317 --state-file .codex-channels/state.json
npx @cafitac/codex-channels plugin-bootstrap --scope workspace

Usage model

• codex-channels runs as a local interaction runtime.
• A Codex app-server bridge or higher-level client feeds interaction requests into it.
• submit can run a compact one-off publish-and-wait loop for a single interaction.
• bridge-stdio can expose the bridge over stdin/stdout while simultaneously hosting the local runtime for user responses.
• bridge-spawn can host the local runtime and spawn a Codex app-server-compatible child process for full bridge orchestration.
• A backend delivers those requests to a local UI or a remote channel.
• The first remote backend scaffolds target Slack, Discord, and Telegram.
• The user's decision is returned to the original request source and marked resolved.

Integration model

• Use HTTP or the CLI for third-party integrations. If you are writing a Python, Rust, Java, or other custom runtime, the simplest path is the local HTTP surface or CLI commands such as submit, inspect, and reply.
• Use JSON-RPC only for the Codex bridge layer. bridge-stdio and bridge-spawn exist for Codex app-server style integration and are not the recommended default for general custom tools.

Local release preflight

Before pushing, tagging, or triggering the release workflow, run:

npm run preflight:release

This mirrors the release-critical local checks:

• npm run check
• npm run build
• npm test
• npm run pack:preview
• npm run publish:dry-run

For a faster developer loop that skips the pack/publish simulation, use:

npm run preflight:ci

Low-noise follow mode

When you want to keep an eye on the queue without repeated manual polling:

codex-channels watch

It prints the initial summary once and then only prints again when runtime reachability, actionable count, the latest actionable interaction, or the next-step recommendation actually changes.

Watch mode now includes a compact hint: line with the current best next command whenever it emits a summary.

When you want low-noise monitoring plus automatic resolution of the next request once it appears, use codex-channels follow --text ....

You can narrow watch and follow to one source, kind, or interaction id with --source, --kind, or --focus-id.

When a newer published version exists, human-facing commands such as doctor and plugin-bootstrap now print a compact [CODEX-CHANNELS] Update available ... hint on stderr, plus the exact update and re-bootstrap commands.

operator-status now distinguishes the latest actionable interaction from the latest overall interaction so recently resolved items remain visible in the summary.
