ng-new

ng-new is a command for coding agents from FlyFission/nuclear-grade-context-engineering. It costs 0 tokens per session (653 once invoked), scanned A, original, MIT.

A command for creating or updating a change record, which documents planned work, risks, required files, and proof for a pull request.

In plain words
What is it for?
Use it to start or revise a real change record, including work involving previews, self-checks, handoffs, operational lessons, or supplier checks.
Why use it?
It prevents important AI-assisted changes from starting without a clear scope or evidence of completion.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

ng-new 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.

How it starts

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ng-new

Portable command prompt generated from skills/creating-change-records/SKILL.md. Edit the skill, then run python tools/ng.py gen-commands; do not edit this file by hand.

Creates or updates Quick or Standard change records, adds the required files, and refreshes what each claim must prove for an evidence-backed pull request. Use when starting or revising a change record. Do not use for a one-off throwaway script, or for work that belongs in an existing record rather than a new one.

Use when

  • You are starting a real AI-assisted change.
  • You are updating a record after the scope, proof, risk, or release posture changed.
  • You are preparing a pull request that needs evidence beyond the usual review notes.
  • A preview, a self-check, a handoff, a lesson from operation (OPEX), or a supplier trust check is in play and needs a record.

Do not use when

  • The work leaves no lasting artifact and no need for review.
  • The request is only to browse or explain existing docs.
  • You only need to pick the mode / grade the change's risk, not author the record yet -- use rating-change-risk instead.

Inputs

  • The chosen mode from risk.md or from the risk-rating skill.
  • A questioning-attitude screen, when uncertainty, AI power, dependency trust, or release stakes are real.
  • Templates under templates/quick/ or templates/standard/.
  • The files the change affects and the proof commands.
  • An existing record, if there is one.

Prompt text

Create or update a Nuclear-grade change record.

Inputs:
- slug: <slug>
- mode: <quick|standard>
- scope: <summary>
- affected files/assets: <list>
- questioned assumptions: <list>
- what the change must prove: <command/review/evidence>
- safety-habit (HPI) records started: <turnover/self-check/opex/supplier-trust/none>

Use the repo templates. Keep the record short. Lean on links, and point at evidence. Include the required links, the conditions for being done, and a note on where the ideas come from. Do not imply formal assurance or compliance.

Return:
- the required files for the chosen mode, named -- Quick: risk.md, proof.md; OR Standard: risk.md, basis.md, plan.md, trace.md, verification.md, ship.md (name only the set for the mode in play)
- the filled-in content for those files

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.

ng-new is a command published in the GitHub repository FlyFission/nuclear-grade-context-engineering (33 stars, last pushed 26d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 653 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
