atom-new

A project-starting workflow based on Atom, a project-starter template. It finds the installed Atom checkout and follows its current instructions to create a new repository.

In plain words
What is it for?
It is for scaffolding a new project or repository from Atom, then continuing through Atom's setup and project-constitution flow.
Why use it?
It keeps the setup process tied to the installed template instructions, so the skill does not become outdated when Atom changes. It stops if Atom is not installed.

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 C, and why

atom-new scanned grade C with 2 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

atom-new — bootstrap a new project from atom

This skill is a thin launcher. It does not contain the bootstrap steps. The single source of truth is Mode 1 of AGENTS.md in the installed atom checkout. Your job is to find that file, read it, and run its flow conversationally against the user's chosen directory.

Why thin: atom is distributed as a git checkout that the user upgrades in place (atom upgrade). If this skill restated the bootstrap steps, the two would drift. Instead it points at the live instructions so the flow is always whatever the installed atom says it is.

Step 1 — locate the installed atom

Resolve the atom source directory, in this order:

  1. $ATOM_SOURCE_DIR (if set)
  2. $ATOM_INSTALL (if set)
  3. ~/.atom/atom/ (the canonical install location)

A directory is a valid atom checkout if it contains both a VERSION file and AGENTS.md. Verify before proceeding.

If no atom checkout is found, stop and tell the user — do not improvise a bootstrap from memory:

I couldn't find an atom install (looked in $ATOM_SOURCE_DIR, $ATOM_INSTALL, and ~/.atom/atom/). Install it once with:

curl -fsSL https://raw.githubusercontent.com/machbuilds/atom/main/install.sh | bash

Then re-run /atom-new.

Step 2 — read the real instructions

Read these from the resolved atom directory (not from this skill, not from memory — they evolve between releases):

  • AGENTS.mdMode 1: Bootstrap a new project. This is the canonical, ordered flow. Follow it exactly.
  • The docs AGENTS.md tells you to read, in the order it lists them (docs/VOICE.md, docs/WORKFLOW.md, docs/PATTERNS.md, docs/LESSONS_LEARNED.md, docs/HOW_TO_WRITE_CONSTITUTION.md, and the conditional ones).

Whatever Mode 1 says wins over anything summarized here.

Step 3 — ask where the project goes

This skill can fire from any directory, so you cannot assume the current working directory is where the new project should live. Before scaffolding, confirm the target:

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.

atom-new is a skill published in the GitHub repository machbuilds/atom (2 stars, last pushed 2mo ago), licensed MIT. It adds 93 tokens to every session and 953 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
