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-migration 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 8d 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.

Nylo v6 to v7 Migration

Spawn the nylo-v6-to-v7-migrator agent to migrate the current Nylo Flutter project from v6 to v7. The agent handles the full migration — discovery, task list, implementation, and verification.

When to Use

  • User wants to migrate a Nylo Flutter v6 project to v7
  • User is getting errors after updating Nylo dependencies to v7
  • User asks about v6-to-v7 breaking changes

Steps

  1. Spawn the migrator agent using the nylo-v6-to-v7-migrator agent type. The agent will:

    • Scan the v7 boilerplate and changelog
    • Analyze the user's v6 project
    • Present a migration task list for approval
    • Implement changes one category at a time
  2. After the agent completes, run a post-migration verification pass using the maps below.

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.
