What it does

Berd Monitor is an agent skill from block/berd, published by the product's own GitHub organization. Run a long-lived command outside the current Berd turn and wake the owning session with actionable stdout. Use for builds, tests, reviews, deployments, polling, watchers, and other external waits.

Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Deployment. The repository describes itself as: a desktop app for getting work done with any model. The licence is Apache-2.0.

When your agent uses it

  • Other external waits
  • Tasks that involve Deployment

Example prompts

  • “/berd-monitor”

What it can do on your machine

Read from SKILL.md and the folder at commit d980f51. 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

Berd Monitor loads about 467 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 203 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~467

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.

Berd Monitor

Use berd-monitor when a command may outlive the current turn. It detaches the producer from Berd and the agent harness, buffers output across delivery failures, and sends complete stdout lines to the exact originating session.

Run short, bounded commands normally. Do not hold a turn open with sleep, polling, log tailing, or a foreground timeout.

Start

bash
berd-monitor run \
  --state-key <stable-key> \
  --label '<concise source name>' \
  --instructions '<short event-handling guidance>' \
  -- <producer-command> [args...]

AGENT_SESSION_ID selects the current session. Use --session-id only for another positively identified session; never infer a session from the working directory. The command prints the detached monitor PID. After checking the monitor's watcher.log under the printed state directory when diagnosis is needed, continue other work or end the turn—never wait on the detached PID.

The producer's stdout is the event API:

  • emit concise, newline-terminated milestones and flush promptly;
  • put verbose output and diagnostics in durable logs or stderr;
  • avoid NUL bytes and emit a final summary when practical.

Default --if-running steer adds an event to an active run or starts a new turn. Use --if-running queue only when the active run must not be steered. Pending events retry without being dropped, and a trailing partial line is delivered when the producer exits.

Delivered messages are visibly labeled as coming from berd-monitor. Stop a monitor with:

bash
berd-monitor stop --state-key <stable-key>
