creative-phase-enforcement

A gate for Level 3 and Level 4 tasks, meaning changes that affect several components or the system’s architecture. It requires important design choices to be written down before implementation continues.

In plain words
What is it for?
Use it before implementing complex features to identify design decisions, record them, and verify that the implementation can proceed.
Why use it?
It prevents coding from starting while major design decisions are still unclear or undocumented.

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

creative-phase-enforcement 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.

Origin

This is a copy

100% identical to creative-phase-enforcement — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

CREATIVE PHASE ENFORCEMENT

TL;DR: This document implements strict enforcement of creative phase requirements for Level 3-4 tasks, ensuring all design decisions are properly documented and verified before implementation can proceed.

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.

creative-phase-enforcement is a cursor rule published in the GitHub repository alkoleft/platform-context-exporter (48 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,123 tokens. A static security scan graded it A with 0 findings. It is 100% identical to creative-phase-enforcement, differing in 0 lines, and is treated as a copy.
