ng-intent

A planning prompt that states an agent’s intended action, reason, expected result, backup, and stopping conditions before a critical change.

In plain words
What is it for?
Use it before deployments, migrations, data changes, public claims, dependency or model swaps, and releases.
Why use it?
It gives reviewers a chance to question the reasoning before an action that may be difficult to undo or affect more than one file.

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-intent 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 3d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ng-intent

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

States what an agent intends to do and why before a critical or irreversible action, so a reviewer can challenge the thinking and not just the result. Use before deploys, migrations, public claims, or trust changes that deserve a stated intent, expected result, abort criteria, and backup. Do not use for routine reversible edits, and never treat the stated intent as proof the agent understood.

Use when

  • Before a deploy, migration, data change, public claim, dependency or model swap, or release.
  • When an action is hard to reverse, or its blast radius is more than the immediate file.
  • When you want a reviewer's eyes on the reasoning and the abort criteria before execution.
  • When standing authority lets an agent proceed unless told no, and the team needs the "no" window.

Do not use when

  • The action is a routine, reversible edit with obvious proof and no trust boundary.
  • An incident is live and the next move is stabilization, not a fresh proposal.
  • Someone wants the declaration treated as a guarantee or certification.

Inputs

  • The intended action and the exact target.
  • The reasoning and the evidence that says the preconditions are met.
  • The expected result, and the signals that would mean it went wrong.
  • The abort and rollback criteria, the decision rights, and who is backing up the action.

Prompt text

Declare intent before this action the Nuclear-grade way.

Inputs:
- intended action and target:
- reasoning / evidence preconditions are met:
- expected result:
- abort criteria (numbers where possible):
- rollback (and is it verified?):
- who may stop it, by when / backup watcher:

Return:
- "I intend to <action> on <target> because <evidence/reasoning>"
- the expected result and the precise signals that would falsify it
- the abort criteria and the verified rollback
- the decision rights and the backup
- after acting: the actual result compared to the expected result, and any gap

State what would prove this wrong, not just what success looks like. Treat the stated intent as a proposal to review, not proof the agent understood. Do not imply certification or formal assurance.

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-intent is a command published in the GitHub repository FlyFission/nuclear-grade-context-engineering (33 stars, last pushed 24d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 622 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.
