mode-transitions

mode-transitions is a cursor rule for Cursor from alkoleft/platform-context-exporter. It costs 0 tokens per session (907 once invoked), scanned A, a copy of mode-transitions, MIT.

A workflow rule that checks whether quality validation has passed before allowing a project to enter build mode. Build mode is the stage where implementation work begins.

In plain words
What is it for?
Use it to enforce a validation gate between quality assurance and building the project.
Why use it?
It prevents implementation from starting while required technical checks are incomplete or failing.

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

mode-transitions 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 yesterday.

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 mode-transitions — 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.

VAN QA: MODE TRANSITIONS

TL;DR: This component handles transitions between modes, particularly the QA validation to BUILD mode transition, and prevents BUILD mode access without successful QA validation.

🔒 BUILD MODE PREVENTION MECHANISM

The system prevents moving to BUILD mode without passing QA validation:

graph TD
    Start["User Types: BUILD"] --> CheckQA{"QA Validation<br>Completed?"}
    CheckQA -->|"Yes and Passed"| AllowBuild["Allow BUILD Mode"]
    CheckQA -->|"No or Failed"| BlockBuild["BLOCK BUILD MODE"]
    BlockBuild --> Message["Display:<br>⚠️ QA VALIDATION REQUIRED"]
    Message --> ReturnToVANQA["Prompt: Type VAN QA"]

    style Message fill:#ff5555,stroke:#dd3333,color:white
    style ReturnToVANQA fill:#4da6ff,stroke:#0066cc,color:white

Implementation Example (PowerShell):

# Check QA status before allowing BUILD mode
function Check-QAValidationStatus {
    $qaStatusFile = "memory-bank\.qa_validation_status" # Assumes status is written by reports.mdc
    
    if (Test-Path $qaStatusFile) {
        $status = Get-Content $qaStatusFile -Raw
        if ($status -match "PASS") {
            return $true
        }
    }
