just-do-it-swarming

just-do-it-swarming is a skill for Claude Code, Codex from etr/groundwork. It costs 39 tokens per session (3,480 once invoked), scanned A, original, MIT.

A task-running method that assigns remaining tasks to separate agent sessions, called a swarm, so each task has its own working context.

In plain words
What is it for?
Running remaining tasks in parallel or separate sessions through the just-do-it-swarming command, when agent teams are enabled.
Why use it?
Separate sessions help prevent information from many tasks accumulating in one context, especially for batches larger than five tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

just-do-it-swarming scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Swarming Batch Task Execution

Executes all remaining tasks using agent teams for context isolation. Each task runs in a separate teammate session with its own context window. Teammates are full Claude Code sessions that can spawn subagents (Plan, task-executor, 9 validators), solving the context accumulation problem of inline batch execution.

When to use this vs /groundwork:just-do-it:

  • Use this (/groundwork:just-do-it-swarming) for large batches (>5 tasks) where context accumulation is a concern
  • Use /groundwork:just-do-it for small batches or when agent teams are not available

Requirement: Agent teams must be enabled (CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS: "1" in settings.json env section).

Model: Teammates spawn with model: "opus" for extended context.

Pre-flight: Model Recommendation

Your current effort level is {{effort_level}}.

Skip this step silently if effort is high, xhigh, or max (the scale is low < medium < high < xhigh < max, so xhigh and max are already above high) AND you are Sonnet or Opus. If effort is low or medium (i.e. below high), you MUST show the recommendation prompt — regardless of model. If you are not Sonnet or Opus, you MUST show the recommendation prompt - regardless of effort level.

Otherwise → use AskUserQuestion:

{
  "questions": [{
    "question": "Do you want to switch? Team orchestration with worktree coordination across agents benefits from consistent reasoning.\n\nTo switch: cancel, run `/effort high` (and `/model sonnet` if on Haiku), then re-invoke this skill.",
    "header": "Recommended: Sonnet or Opus at high effort",
    "options": [
      { "label": "Continue" },
      { "label": "Cancel — I'll switch first" }
    ],
    "multiSelect": false
  }]
}

If the user selects "Cancel — I'll switch first": output the switching commands above and stop. Do not proceed with the skill.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
