What it does
Bb CLI is an agent skill from davidondrej/skills. Use this when controlling bb. The bb CLI inspects and manages threads, environments, projects, machines, providers, skills, plugins, settings, terminals, and other BB services.
Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/app-settings.md`, `references/command-index.md` and `references/configuration.md`).
It sits in Agent Workflows. The repository describes itself as: access to david ondrej's personal agent skills. The licence is MIT.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/bb-cli”
What it can do on your machine
Read from SKILL.md and the folder at commit ea32e5f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Bb CLI loads about 823 tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 378 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- bb-cli
- description
- Use this when controlling bb. The bb CLI inspects and manages threads, environments, projects, machines, providers, skills, plugins, settings, terminals, and other BB services.
BB CLI
Never inspect or message other threads unless the user explicitly requests that action.
Use bb for BB state and actions. Inspect the current context before you choose IDs, machines, workspaces, providers, or models.
Start with context
bb status --jsonUse JSON when command output controls later work. Use human output for quick inspection.
Run bb --version for the CLI version. Use bb --help or bb help [command]
for help. Run bb guide for the system overview. Run bb guide <chapter> for one
area. Use bb <group> --help for current flags and defaults.
A standalone CLI targets http://127.0.0.1:38886. Use BB_SERVER_URL and BB_HOST_DAEMON_PORT only for an intentional non-default target.
Read only the relevant reference
- Read references/command-index.md to find the exact core command path. Use live help for current flags and defaults.
- Read references/configuration.md for settings, agent instructions, skills, remote clients, and environment setup scripts.
- Read references/thread-creation.md before you spawn or fork threads, create projects, select machines, or create environments.
- Read references/thread-operation.md for messages, queues, interactions, panes, terminals, inspection, and long-running commands.
- Read references/failure-recovery.md when a thread fails, stops, or needs plan or goal recovery.
- Read references/theme-commands.md for palette and favicon commands. Read references/theming.md before you create or edit theme CSS.
- Read references/plugins.md for plugin discovery, install, build, update, configuration, runtime, and contributed commands.
- Read references/app-settings.md for complete app setting keys and effects.

Command habits
- Resolve names and IDs with a list or show command before mutation.
- Pass an explicit project when a command can act across projects.
- Pass an environment or machine selector when the default host is uncertain.
- Query provider models on the machine that will run the thread.
- Prefer non-interactive commands and machine-readable output for automation.
- Pass
--yesfor a confirmed destructive command in a non-interactive shell. - Treat plugin commands as normal top-level commands after installation.
- Inspect real status, logs, API results, or diffs instead of assumptions.
- Keep file paths on the machine that owns the selected workspace.
- BB rejects symlinks as project/environment roots (
Root path ... must not be a symlink). Use real directories. Before a rename or rollback, check every affected environment and thread; changing only project sources is not enough.
Common checks
bb project list --json
bb machine list --json
bb provider list --environment "$BB_ENVIRONMENT_ID" --json
bb thread show "$BB_THREAD_ID" --json
bb environment status "$BB_ENVIRONMENT_ID" --json
bb plugin list --json
bb skill list --environment "$BB_ENVIRONMENT_ID" --jsonCompletion
Confirm the command result and any affected thread, environment, plugin, or remote service. Report the stable ID or URL that the user needs next.
