At a glance

Inspect or change global and per-host limits on concurrently running BB threads.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Concurrency Limit is an agent skill from get-bb/bb. Inspect or change global and per-host limits on concurrently running BB threads.

Its SKILL.md is about 150 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The agent IDE that builds itself. The licence is MIT.

Example prompts

  • “/concurrency-limit”

What it can do on your machine

Read from SKILL.md and the folder at commit 53c1e87. 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

Concurrency Limit loads about 147 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 50 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~147

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.

Concurrency limits

Use bb concurrency-limit status --json to inspect current limits.

sh
bb concurrency-limit global [unlimited|<limit>] [--json]
bb concurrency-limit host <host-id> [auto|<limit>] [--json]

Automatic host limits allow one thread per available processor. Resolve the host with bb machine list before changing a host limit. Omit the value to inspect it; change limits only for the requested scope and verify the resulting status.
