mass-ulw

mass-ulw is a skill for Claude Code, Codex from daeryundf2-prog/LAZYANTIGRAVITY. It costs 67 tokens per session (1,222 once invoked), scanned A, original, MIT.

A workflow for splitting a large coding task into dependency-ordered groups of work for multiple agents. It runs independent groups in parallel and waits for required earlier work before starting later groups, followed by verification.

In plain words
What is it for?
Use it for fan-out work, task graphs, and multi-agent changes with separate write areas and required follow-up checks.
Why use it?
It reduces coordination errors when a task has many parts that can run at the same time but still depend on one another.

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

mass-ulw 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 11d 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.

mass-ulw

Use this skill when the work splits into many pieces and some pieces depend on others. If every piece is independent, a single invoke_subagent call with several entries is enough; you do not need this skill.

Antigravity has no DAG engine. You are the scheduler: you hold the graph, launch one wave at a time with a single invoke_subagent call, and start the next wave only after the current one reports back. Read references/planning.md in this skill's directory before defining the first wave.

1. Lock the topology

Before writing any node:

  1. List the 1 to 6 top-level components that can each succeed or fail on their own. Every node belongs to exactly one.
  2. For each component, ask how to break it into small pieces that can run at the same time. Keep a piece whole only when splitting it would put two writers on one file, cut a single judgment call in half, or cost more in briefing than in doing.
  3. Draw the dependency edges. An edge means "B needs A's finished result". Never add an edge just to pass along a fact you already know; paste the fact into B's prompt instead.
  4. Self-check: no cycles, every edge points at a real node, every wave has a runnable node, no two nodes in the same wave write the same file.

Write the plan out before launching: waves, node ids, model per node with a one-line reason for anything above flash, and the verification wave.

2. Route each node

Start every node at the cheapest lane and climb only with a stated reason.

Lane Model Use for
lookup flash_lite file listing, single grep, lint read
default flash mechanical or single-area code, search, drafting
hard pro cross-module reasoning, security, architecture, adversarial review
verdict inherit at most one node per graph, only on a Claude session, for the final call

Agent types: explore for in-workspace search, librarian for upstream code and docs, research for read-only broad surveys, self for anything that writes. A wave where every node is pro is a routing mistake.

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.
