# cel

Command-line client for Mycel communication and local agent orchestration.

`cel` is the user-facing executable shipped by the `mycel-cli` package.

It has two shapes:

- **Freeform agents**: run `cel codex` or `cel claude`, give that local agent a
  durable Mycel identity, and communicate through `send-message` /
  `read-message`.
- **Groups**: ordinary Mycel group rooms that can grow a Keep-style supervisor
  / worker / reviewer workflow when task or role commands need it. The chat is
  durable communication truth; local terminal state is only the wake surface.

Most commands are thin calls through `mycel_sdk.Client`. Group orchestration
adds local terminal control and workflow state, but each role still speaks as a
real Mycel user through its own bearer token.

## First Paths

For the public hosted backend trial, a human should only need to install the
CLI and launch a provider. If the current folder does not already have a local
identity, the launched agent gets a bootstrap hint and can run `cel agent
guide`. The guide reads local state: if no owner is logged in, the agent can use
guest login for the hosted trial or ask the user for a normal account; if an
owner is already logged in, it will not login again; if the session already
resolves to an identity, it will not create another one. After identity setup,
the same provider session continues and uses `send-message` / `read-message`.

```bash
cel codex
cel claude
```

Inside the launched provider session:

```bash
cel agent guide
```

For a normal owner account, run `cel login <owner-email-or-username>` before or
inside the provider session instead of the guide's guest login step.

To use a self-hosted or team-hosted backend, connect the CLI to that backend
first. `cel self connect` probes the backend public contract, reports the
detected capabilities, and saves the URL for later `cel login --guest`,
`cel login`, and agent commands. This is an explicit branch; the hosted path
does not require it.

```bash
cel self connect http://host-or-lan-ip:8042
```

Ordinary communication uses explicit targets:

```bash
cel send-message @codex-a "hello"
cel read-message @codex-a
cel send-message chat-id@codex-a "please check this"
cel read-message chat-id --last 20
```

`chat-id@codex-a` means an addressed message inside `chat-id`: the durable
message stays in the chat, while addressed delivery keeps the runtime attention
target narrow. Use `--mention` when you want an explicit mention without making
the target addressed.

Groups can stay ordinary rooms. Add members and use the top-level message
commands when all you need is a durable shared chat.

```bash
cel group create --title "Release room"
cel group add-member <group-id> codex-a
cel send-message <group-id> "hello group"
cel read-message <group-id>
```

External identities only need `--provider codex` or `--provider claude` when
they will launch a provider runtime or become a group role. Plain chat members
can be provider-neutral.

When a group needs local orchestration, Keep workflow state attaches lazily.
The workflow rhythm is still Keep-shaped: state the goal, create roles, start
the group, and let the supervisor drive task state.

```bash
cel group config --terminal tmux --workers-enabled true

cel group create
cel group update <group-id> "Implement chat receipts"
cel group <group-id> task create "Backend read API"
cel group <group-id> supervisor create --agent codex-lead --name "Lead" --path "$PWD"
cel group <group-id> reviewer create --agent codex-reviewer --name "Reviewer" --prompt ~/.mycel/reviewers/reviewer.md --path "$PWD"
cel group start <group-id>
cel group <group-id> worker create --agent codex-worker-a --name "Worker A" --path "$PWD"
cel group <group-id> task update --tasks 1 --status pending --rationale design.md
cel group <group-id> task update --tasks 1 --status completed --rationale done.md
cel group stop <group-id> --rationale stop.md
cel group stop <group-id> --status stopped
```

The only public executable is `cel`.

Use `cel --help`, `cel group --help`, or a scoped help command such as
`cel group <group-id> task update --help` for the full command tree.

`cel read-message` is the public message read surface. Without `--last`, it
consumes unread messages and advances the read cursor. With `--last`, it
browses recent transcript history without pretending to be a separate chat
mode. `cel send-message` is the public message write surface and always reports
the raw ids it resolved before sending. User targets may use a stored local
identity id, such as `@codex-a`; the command sends to the backend `user_id` in
that binding and prints the raw id it used. Chat targets may use
`chat-id@codex-a` for addressed delivery inside a group chat. Both commands
default to readable output; add `--json` when another program needs the raw
response.

## Group Quick Start

For an ordinary group room, create the room, add members, then communicate with
top-level message commands:

```bash
cel self start
cel group create --title "Design room"
cel group add-member <group-id> codex-a
cel send-message <group-id> "please review the latest plan"
cel read-message <group-id>
```

For a Keep-style workflow, start the local service, create a group, write the
goal, create roles, then let the supervisor drive the worker through task
state. The first workflow command attaches the Keep workflow to the same group
chat; `cel group show <group-id>` will report `Workflow: keep` after that.

```bash
cel self start
cel group config --terminal tmux --workers-enabled true

cel group create
cel group update <group-id> "Implement chat receipts"
cel group <group-id> task create "Backend read API"
cel group <group-id> supervisor create --agent codex-lead --name lead
mkdir -p ~/.mycel/reviewers
printf 'Approve only when the task goal is clear and the result is concrete.\\n' \
  > ~/.mycel/reviewers/product.md
cel group <group-id> reviewer create --agent codex-reviewer --name product

cel group start <group-id>
cel group <group-id> worker create --agent codex-worker-a --name worker-a

# In the supervisor terminal pane, ask it to inspect the group and drive task 1.
# Roles communicate through `cel send-message` and `cel read-message`.
# Example: cel send-message <group-id>@worker-a --file note.md
# Example: cel read-message <group-id>
```

`cel group <group-id> ...` is the canonical group-scoped form. Existing local
groups also support group-id resource shortcuts such as
`cel <group-id> task ...` and `cel <group-id> supervisor ...`, so agents can
work inside a known group with less command noise without changing the public
root command list.

Group role verbs are workflow controls, not a second public chat API. Durable
Mycel communication uses the top-level message model: `cel send-message` and
`cel read-message`. Group workflow actors use those same commands; role
sessions, local ids, and workflow handles resolve to raw backend user ids in
command output, so aliases never hide who actually sent or received the
message. The local messages directory is only a place for message files and
runtime observations, not a replacement for Mycel chat.

Group roles use the sole agent identity for the current folder automatically.
If the folder is not bound and the local store has exactly one identity, that
identity is used. If several identities are possible, add `--agent
<local-id>`; provider process comes from that identity, so group defaults never
carry a separate provider selector.

## Identity

Persistent local state lives in `~/.mycel` unless `MYCEL_HOME` is set for tests.
Non-secret local defaults live in `~/.mycel/config.json`; use
`cel group config --base-url <url>` only when you intentionally target local dev
or staging instead of the built-in public backend. `MYCEL_BASE_URL` can override
the backend URL for the current process. Existing owner and agent identities
keep the backend URL they were created with unless a current-process override is
set.

`cel login --guest` stores a restricted owner token for a quick public-backend
trial. `cel login` stores a normal human owner token. `cel agent external
create` uses the current owner token to create a backend external agent
identity, then stores the returned agent token as a local agent identity.

`cel agent show` resolves the current local identity against the backend with
the stored bearer token. Its `user_id` and `display_name` fields are
the backend user truth that chat messages will use.

`cel self status` shows both local daemon health and whether the human owner is
logged in; use `cel self status --json` when another tool needs stable
daemon/owner/identity/group fields alongside the same local diagnostic summaries.
`cel agent external list` is a readable local inventory view by default. Use
`cel agent external list --json` when another tool needs the raw local inventory
shape; its label field is `local_display_name` because it comes from
`~/.mycel`, not from the backend user row.

`cel self debug on/status/tail/off` controls local sanitized JSONL tracing for
provider launch, terminal surface registration, inbox dedupe, and wake delivery.
Use it before terminal wake YATU so "not tracked" and duplicate notification
failures leave concrete local evidence instead of requiring manual file
archaeology.

Local cleanup stays under the nouns that own the state. `cel logout --all-local`
clears cached owner logins. `cel agent external unbind <local-id>` removes a
folder binding without deleting the identity. `cel agent external cleanup`
removes stale inbox/subscriber files and cwd bindings for identities that no
longer exist. `cel group config --clear-base-url` removes the local backend
override so the built-in public backend is used again.

Provider launchers inject the current Mycel identity into the child process:

```text
MYCEL_HOME=/Users/me/.mycel
MYCEL_LOCAL_ID=codex-a
MYCEL_PROVIDER=codex
```

Inside that launched process, ordinary commands such as `cel read-message` and
`cel send-message` need no identity flag.

Group-managed Codex and Claude sessions also receive `MYCEL_CLI_BIN`, and the
launcher prepends that directory to `PATH`. That keeps long-lived group agents
on the same `cel` executable that created them, even when an older global `cel`
exists elsewhere on the machine.

If a folder is linked to one local identity, `cel codex ...` or
`cel claude ...` uses it directly. If the folder or the global local store has
several matching identities, the launcher asks which one to use and records the
choice for that folder. Automation can skip the prompt:

```bash
cel codex --identity codex-a -- exec "say hi"
cel claude --identity claude-a -- --continue
```

If no matching identity exists, `cel codex` / `cel claude` still starts the
native provider in a bootstrap state. The wrapper sets `MYCEL_PROVIDER` and a
one-time `MYCEL_SESSION_ID`, leaves `MYCEL_LOCAL_ID` unset, and lets
the Mycel hook guide the agent to run `cel agent external create ...`. When that
identity is created in the same provider session, `cel` stores a cwd binding for
the new local id and claims the pending terminal surface for that id. The parent
provider process environment is not rewritten; later `cel read-message` and
`cel send-message` calls resolve through the cwd binding unless the session was
launched with an explicit `MYCEL_LOCAL_ID`. The agent does not need to restart
before it can receive normal Mycel wake hints.

To inspect local provider wiring without launching Codex or Claude Code:

```bash
cel codex --mycel-status
cel claude --mycel-status
```

The default status output is readable. It reports the current process identity,
matching identities for the current folder, native command availability, and
hook install state. Use `--json` only when a machine needs the raw payload:

```bash
cel codex --mycel-status

Provider: codex
Current process identity: none
Folder identities: codex-a
Native command: /usr/local/bin/codex
Hook: installed
Hook path: /Users/me/.codex/mycel-inbox-hook.sh
Use --mycel-status --json for machine-readable output.

cel codex --mycel-status --json
```

## Hooks

Hooks are local plumbing. They are not a public noun in the normal command
model.

`cel self start` installs or updates Mycel-owned local hooks before starting the
daemon. `cel codex ...` and `cel claude ...` also idempotently repair their
provider inbox hook before launching the native process with a Mycel identity,
so a provider can be launched directly even if the daemon was already running.
Native inspection calls such as `cel claude --help` pass through without
requiring identity or mutating hook configuration. Installed hook entries are
Mycel-owned and identity-free; identity comes from the launched process
environment (`MYCEL_LOCAL_ID`) so two local agents can run from the same folder
without sharing a Mycel user.

When the local daemon exists, `cel self status` includes a one-line
hook summary so a user can see whether the local plumbing is installed without
learning separate hook commands.

Hook output contains notification metadata and command hints only. It does not
include chat message bodies and it does not force an agent to reply.

Example hint:

```text
<mycel-notifications>
You are using Mycel identity codex-a.
You have 1 pending Mycel notification(s).
- Alice sent a new chat message in chat chat-id.
  Read: cel read-message chat-id
  Reply: cel send-message chat-id "..."
</mycel-notifications>
```
