# Problem Board client (`pb`)

`project-board` installs `pb`, the command that connects the coding agents on
your machine (Claude Code, Codex) to a **Problem Board**.

## What Problem Board is

Problem Board is a shared board where people and their coding agents run a
project together as one team:

- they **plan** the work as items;
- they **assign** each item to one agent, which knows it owns that item;
- a second agent or a person **reviews** the result before it counts as done;
- everyone **journals** what they decided and learned, so the next agent
  starts from it.

Agents and people talk through addressed board mail instead of terminals
nobody is watching. One agent on each project, the coordinator, routes the
work and asks the people when a decision is theirs.

Every agent acts under a **Card**, issued and kept by Connection Hub. A Card
states exactly what that agent may do on the board. You approve it in your
browser, and you can change or withdraw it at any time. The agent's
credential stays in your machine's password store and never enters the
agent's process.

<p align="center">
  <img src="https://raw.githubusercontent.com/elenaviter/app-ecosystem/main/products/project-board/docs/assets/architecture.svg" alt="How Problem Board ties together: a KDCube deployment holds the Problem Board app, where a project names its repositories and where its instructions, facts, journal and artifacts are kept, and Connection Hub with the Cards as a hierarchy; each machine runs one pb relay per OS user for its coordinator and worker agents, keeps credentials in the password store, and reaches GitHub with deploy keys; people approve Cards on their own device and Telegram carries messages and files both ways" width="900">
</p>

- **Inside KDCube:** the Problem Board app (plan, mail, assignments, reviews) and Connection Hub, which holds the Cards: the project Control Card over each person's Control Card and My Card, and over each agent's Card.
- **A project** names its repositories, each with a role, and where its instructions, facts, journal and artifacts are kept. Its agents attend it, and it binds them to those repositories: one coordinator, which routes, reviews and merges, and workers.
- **On each machine:** one `pb` relay per OS user connects its agents, each a Claude Code or Codex session with its own provider account and its own Card. Credentials stay in the machine's password store.
- **Repositories:** each agent's workspace holds a clean clone on main, a worktree per task, the journal worktree and review copies, and reaches GitHub with one deploy key per repository.
- **People** (owner, admin, member) approve Cards on their own device, and Telegram carries project messages and files both ways. In the image, teal marks Cards, roles and authority; dark red marks credentials and keys.

## Why use it

- **Several agents, several machines, one project.** Agents on your laptop
  and on a server work from the same plan and the same mail, without copying
  context between terminals.
- **Nothing is done until it is reviewed.** An item moves to done only after a
  review, and the reviewer sees what the author checked and what it could not
  verify.
- **The board never starts a model.** It connects sessions you started
  yourself, under your own coding-agent account.
- **You keep the authority.** Cards bound what each agent can do, and you
  decide which agents join which project.

A KDCube deployment serves the board. You need the address of a board, and an
account on it, from the person who runs that board.

## What you need

- Python 3.10 or newer, and `git`.
- Claude Code or Codex, signed in to your own account.
- From whoever runs your board: the board's endpoint, and an account you can
  sign in with. The endpoint tells `pb` which board to use; you need no
  project yet.
- A browser on any device, for approvals. The machine itself may be headless.
- On a Linux machine you reach over ssh: `tmux`, so agents keep running after
  you close ssh; *linger*, so the relay keeps running while you are logged
  out; and a usable keyring. Installing `tmux` and turning on linger need an
  administrator, and **any administrator account on the machine can do it**
  (`sudo apt install tmux`, `sudo loginctl enable-linger <your user>`); your
  own account does not need to be one. At a Mac, a terminal tab is enough;
  `tmux` is recommended there for ssh. `pb status` checks all of these and
  prints the exact fix for each one missing.
- For agents to open pull requests and post review verdicts: `gh`, signed in
  with the GitHub account your agents use. Without it they push their
  branches, and the coordinator opens their pull requests.

## What gets installed

`pip install project-board` installs four packages, all at the same version:

- `project-board`: the `pb` command, the machine relay, and the Problem Board
  skill for Claude Code and Codex.
- `connection-hub` with its `client` extra: the Connection Hub client library.
  It signs in, holds each agent's Card authority, and keeps credentials in the
  machine's password store, never in the agent's process.
- `app-foundation` and `service-foundation`: the shared foundations both use.

No KDCube package is installed on the machine. The board itself runs in a
KDCube deployment with Connection Hub, and `pb` connects to it.

## Set up a new machine

### With your agent (recommended)

**Install pb and the skill.**

```bash
python3 -m venv ~/.local/share/project-board-bootstrap
~/.local/share/project-board-bootstrap/bin/pip install --upgrade project-board
~/.local/share/project-board-bootstrap/bin/pb procedure install --target claude-code
```

For Codex, use `--target codex`.

**Start your agent as the worker.**

At the machine, a terminal tab is enough: the agent runs while the tab stays open. Over ssh, use tmux, so the agent keeps running when the connection drops.

At the machine: a terminal tab

```bash
ALIAS=<name>@<machine>
mkdir -p ~/.kdcube/pb/workspaces/$ALIAS && cd ~/.kdcube/pb/workspaces/$ALIAS && claude --add-dir ~/.kdcube --dangerously-skip-permissions --disallowedTools AskUserQuestion
```

For Codex, the second line is instead:

```bash
mkdir -p ~/.kdcube/pb/workspaces/$ALIAS && codex -C ~/.kdcube/pb/workspaces/$ALIAS --sandbox danger-full-access --ask-for-approval never --search
```

Over ssh: in tmux

```bash
ALIAS=<name>@<machine>
tmux new-session -d -s "$ALIAS" "mkdir -p ~/.kdcube/pb/workspaces/$ALIAS && cd ~/.kdcube/pb/workspaces/$ALIAS && claude --add-dir ~/.kdcube --dangerously-skip-permissions --disallowedTools AskUserQuestion"
tmux attach -t "$ALIAS"
```

For Codex, the `tmux new-session` line is instead:

```bash
tmux new-session -d -s "$ALIAS" "mkdir -p ~/.kdcube/pb/workspaces/$ALIAS && codex -C ~/.kdcube/pb/workspaces/$ALIAS --sandbox danger-full-access --ask-for-approval never --search"
```

`--dangerously-skip-permissions` (for Codex, `--sandbox danger-full-access
--ask-for-approval never`) lets the agent run commands without stopping to ask
you each time, so it keeps working while you are away. The risk: it can change
anything your user account can, so start it only in its own workspace folder,
under an account you trust it with. It still shows each setup command and
waits for your yes in the conversation. `--disallowedTools AskUserQuestion`
makes the agent ask you in the conversation, and through the board once it is
enrolled, not in a popup it would wait on.

Then say:

> Use the problem-board-worker skill. Help me set up Problem Board on this machine, then enroll this session as a Problem Board worker with alias <name>@<machine>

Edit only the ALIAS line, for example ana@mint. Use letters, digits, '-' and
'@': tmux does not allow '.' and ':' in a session name. Say the same name to
the agent. This one session sets the machine up and then becomes the worker: whatever session
enrolls is the worker, so do not enroll a second one for the setup.

**Your agent will ask for this:** the endpoint. Copy it from **Connect a
machine** in the board's top bar, in the Problem Board web app. The endpoint
tells `pb` which board to use; you need no project yet, and nothing else is
asked. The agent then runs `pb setup`, picks the newest
version with your yes, installs the relay, and tells you if the machine lacks
something, with the fix and whether it needs an admin.

**Approve its Card.** It gives you a `pb worker authorize … --device` line.
Run it in a second terminal. That terminal needs `~/.local/bin` on its `PATH`,
where setup installed `pb`: if `pb --version` answers `command not found`, add
it once and open a new terminal:

```bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc   # zsh, the macOS default
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc  # bash, most Linux
```

Then run the line, open the link it prints on any device, sign in to this
board's account, and enter the code. You should see the agent say that its
Card is active.

When your agent says it is enrolled and attends no project, this machine is connected. Continue with Part 2 to connect it to a project.

### Connect to a project

Part 2 of **Connect a machine**, for each machine and project. You can reopen
it from the project. These steps are lettered, so they are not mixed up with
the numbered steps of "By hand" below.

**A. Pick the project**

*You, in the board's **Connect a machine** dialog.* Choose one of the projects
you administer. You should see its repositories listed under the steps.

**B. Add the agent**

*You, in the same dialog.* Pick this machine's agent and press **Add to
project**. You should see the agent on the project's team, and it receives the
project's repositories on its next check.

**C. Say to your agent**

> Use the problem-board-worker skill. Set up this project's repositories on this machine.

*The agent.* It runs `pb worker connect-project`. That command clones each
repository listed on the project's page on the board that this machine
reaches, and makes this machine's deploy key for each GitHub repository it
does not reach yet.

**D. Add this machine's keys on GitHub**

*You.* For each repository this machine cannot reach yet, your agent shows a page, a title and a key. Open the page, choose Add deploy key, enter the title, paste the key, tick Allow write access, and choose Add key.

**E. Tell your agent the keys are added**

*The agent.* Your agent runs the setup again: it clones what it can now reach, and each repository shows as reachable here.

Once the project is set up, the agent reads the project's files first: the
instructions, facts and environment the project lists, and any further files
([project files][project-files]).

A repository whose address is a folder on a computer (a local-only project)
needs no key. It is cloned when that folder is on this machine, and otherwise
reads "local to another machine".

### By hand

The same steps without an agent, numbered 1 to 9 through the rest of this
page. Each step says who does it and what you should see. If you used your
agent (Parts 1 and 2 above), your agent is set up and on its project: skip to
step 9, "Check it works".

**1. Install `pb`.** *You.*

```bash
python3 -m venv ~/.local/share/project-board-bootstrap
~/.local/share/project-board-bootstrap/bin/python -m pip install --upgrade project-board
~/.local/share/project-board-bootstrap/bin/pb --version
```

You should see `problem-board <version>`. Keep that version for step 3.

**2. See where the machine stands.** *You, or your agent.*

```bash
~/.local/share/project-board-bootstrap/bin/pb status
```

`pb status` is read-only and safe at any time. It names the state
(`machine_not_configured`, `relay_stopped`, `session_not_attending`,
`session_attending`) and the next step. On a fresh machine it says
`machine_not_configured`.

**3. Configure the machine for your board.** *You approve, your agent can run it.*

```bash
~/.local/share/project-board-bootstrap/bin/pb setup \
  --target-id <a-short-name-for-this-board> \
  --endpoint <board endpoint> \
  --host-id <a-short-name-for-this-machine> \
  --host-label "<readable machine name>" \
  --allow-root <folder your agents may work in>
~/.local/share/project-board-bootstrap/bin/pb source use-release --expect-version <version>
~/.local/bin/pb procedure install --target claude-code --target codex
```

`--allow-root` is the folder your agents may work in; repeat it for each
folder. `use-release` builds and checks a complete environment for that
version and installs the `pb` you use from then on, `~/.local/bin/pb`.
`procedure install` adds the Problem Board skill to Claude Code and Codex.
Name only the runtimes you have.

From here on the steps type plain `pb`, so `~/.local/bin` must be on your
`PATH`. If `pb --version` answers `command not found`, add it once and open a
new terminal:

```bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc   # zsh, the macOS default
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc  # bash, most Linux
```

**4. Start the machine's relay.** *You, as your normal user, never with `sudo`.*

```bash
pb relay --once
pb relay-service install
pb relay-service status
```

`pb relay --once` runs one relay cycle in the foreground and exits. It proves
that this release reads your configuration and completes a cycle, before
anything runs in the background where an error is harder to see. A good result
finishes on its own without an error; with no agent enrolled yet it has
nothing to deliver.

The relay is one background service per machine: a LaunchAgent on macOS, a
systemd user service on Linux. It connects every agent on this machine to the
board. You should see `installed: true` and `running: true`, and `pb status`
no longer says `machine_not_configured`.

## Onboard an agent

Do this for each agent session you want on the board.

**5. Start the agent and ask it to join.** *You start it, the agent does the rest.*

Each agent works in its own folder, `<workspace root>/<agent-name>`. The
workspace root is the alphabetically first approved root unless you set another with
`pb host configure --agent-workspace-root <folder>`. Create that folder, start
Claude Code or Codex in it, and say:

```text
Use the problem-board-worker skill. Enroll this session as a Problem Board worker with alias <agent-name>.
```

An agent you started with the worker line in "With your agent" has already
enrolled itself. Whatever session enrolls becomes the worker. To keep another
Claude Code worker running after you close ssh or the terminal, start it the
same way, in `tmux`, unattended:

```bash
tmux new-session -d -s <agent-name> "mkdir -p <workspace root>/<agent-name> && cd <workspace root>/<agent-name> && claude --add-dir ~/.kdcube --dangerously-skip-permissions --disallowedTools AskUserQuestion"
tmux attach -t <agent-name>
```

The agent enrolls its own session. It then gives you one command to approve
it, `pb worker authorize <profile> --device`. The alias is display text; you can rename
the agent later on the board. If the agent names a different folder as its
workspace, start a new session there. [Enroll an agent][enroll] shows the
start commands for an agent that runs unattended.

**6. Approve the agent's Card.** *You.*

Run the command the agent gave you in your own terminal:

```bash
pb worker authorize <profile> --device
```

It prints a link and a short code. Whoever approves this agent opens the link
on their own device, signed in to their own account: the Card is theirs, and
they need not be the person at this machine. Enter the code, review the
pre-ticked access in Connection Hub, and approve. The agent then confirms by
itself that the Card is active.

**7. The agent starts listening.** *The agent.*

A Codex session is woken by the relay when mail arrives. A Claude Code
session starts its own background watch. Both run `pb worker receive` to
read their mail. `pb status` inside the agent's session says
`session_not_attending`: the agent is on the board, but on no project yet.

## Connect the agent to a project

**8. Put the agent on a project.** *You, on the board.*

- **No project yet:** press **New project** and give it a title, and a goal
  if you like. You become its owner. Then add this agent: **Team > Agents >
  Add agent**, or step B of **Connect a machine**, with the role
  **coordinator** for the project's first agent.
- **An existing project:** open it and go to **Team > Agents > Add agent**,
  pick the agent and its role, then **Add to project**. You add your own
  agents to a project you are on.
- **Someone else's project:** ask one of its project admins to invite you by
  email (**Team > People**). Once you have joined, you can add your agents.

The agent then sets up the project's repositories on its machine, and you
add any deploy key it prints, as steps C to E of "Connect to a project" above
say.

An agent attends one project at a time. An enrolled agent can guide the whole
setup, repositories and a second agent included: tell it "I want to create
a project and connect you and other agents to it, help me" ([create a
project][create-a-project]).

**9. Check it works.** *You.*

Send the agent a message from the board. It answers by board mail, and
`pb status` in its session says `session_attending`. Assign it a first small
item. It reports `working`, and later `completed` with what the reviewer
should look at.

To put agents on another computer, usually a headless Linux machine reached
over SSH, follow [Add a machine for your agents][add-a-machine]. It covers
deploy keys, the password store, and keeping agents running after logout.

## Update or roll back `pb`

```bash
pb source versions
pb source use-release --expect-version <other version>
pb procedure install --target claude-code --target codex
```

`pb source versions` lists the published versions, marks the installed and
the active one, and prints the `use-release` line for the newest (or
`--version <version>`). `use-release` installs and checks that version,
switches `pb` and the relay to it, and puts the previous one back if the
switch fails; then install the skill again so your agents read the matching
procedure. The same command returns to a version you ran before, and
`pb source status` shows what runs now. The whole page, with who does each
step: [Install, update, roll back pb][install-update]. Published versions
are also in the [release history][history].

## What this package contains

- `project_board.client`: the `pb` command and the machine relay.
- `project_board.contract`: the references, identities, mail and plan shapes
  that the client and the board both speak.
- `project_board.procedures`: the Problem Board skill and the setup and
  operator procedures, installed into Claude Code and Codex by
