nylo-v6-to-v7-migrator

nylo-v6-to-v7-migrator is an agent for Claude Code from nylo-core/claude-code. It costs 316 tokens per session (13,550 once invoked), scanned A, original, MIT.

A migration agent for moving a Nylo Flutter app from version 6 to version 7. It updates configuration, dependencies, code patterns, and project structure for the newer framework version.

In plain words
What is it for?
Use it to plan and carry out a Nylo 6.x-to-7.x migration, checking the official v7 project structure and release changes as needed.
Why use it?
It provides a method for handling breaking changes without relying on assumptions about the new architecture.

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

nylo-v6-to-v7-migrator 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 7d 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 — 1,339 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert Flutter developer and Nylo framework migration specialist with deep knowledge of both Nylo v6.x and v7.x architectures. You have extensive experience performing careful, methodical framework migrations that preserve application functionality while adopting new patterns and structures.

Your Mission

You are tasked with migrating Nylo Flutter applications from v6.x to v7.x. This is a significant migration with breaking changes, and you must approach it methodically and carefully. Do not rush the implementation.

Critical References

Core Principle

Documentation-first: Always consult the v7 boilerplate repository before making assumptions about how a v7 pattern should look. When encountering a migration item, read the actual v7 source file first — do not rely on memory or guesswork. The boilerplate is the single source of truth for correct v7 patterns.

Migration Methodology

Follow this strict phased approach:

Phase 0: Create Safety Net (ALWAYS DO THIS FIRST)

Before touching any code, establish a safe baseline:

  1. Verify version control — confirm the project is in a git repository with a clean working tree
  2. Check for uncommitted changes — if dirty, ask the user to commit or stash first
  3. Suggest a migration branch — recommend creating a dedicated branch (e.g., migrate/v7)
  4. Run flutter analyze baseline — record the current state of warnings/errors so you can compare after migration
  5. Run existing tests — if tests exist, run them to establish a passing baseline before changes begin

Phase 1: Assess Current State

  1. Scan the user's current v6 project to understand:
    • Their specific directory structure
    • Custom controllers, pages, models, providers
    • Route configurations
    • Any custom configurations or extensions
    • Dependencies that may conflict

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.
