What it does

Check is an agent skill from openwpm/OpenWPM. Use to check on background feature agents launched via /kickoff — running in tmux sessions or docker/podman containers. Reports each agent's state (Working / Idle / Waiting / Done / Error), captures recent output, and offers next-step commands. Trigger when the user says "check on the agent(s)", "how's the kickoff going", or names a feat- / crosslink-task- session.

Its SKILL.md is about 1.5k 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 Containers and Git worktrees. It works with tmux, Docker and Git. The repository describes itself as: A web privacy measurement framework.

When your agent uses it

  • Check on background feature agents launched via /kickoff — running in tmux sessions
  • Docker/podman containers
  • The user says check on the agent(s)
  • Hows the kickoff going

Example prompts

  • “check on the agent(s)”
  • “s the kickoff going”
  • “/check”

Requirements

  • Docker

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Identify agents to check
  2. For each agent, perform these checks
  3. Report
  4. Offer actions

What it can do on your machine

Read from SKILL.md and the folder at commit da628ba. 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

    Shell commands in SKILL.md call:

    • git
    • docker

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and docker, which can reach the network depending on how they are called.

    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

Check loads about 1.5k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 681 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 681 words (~1,531 tokens).

“The user optionally provides an agent name (e.g. crosslink-task-add-batch-retry or feat-add-batch-retry). If no name is given, check all active feature agents (both containers and tmux sessions) and report a summary for each.”
