wingtip-migration-test

wingtip-migration-test is a skill for Claude Code, Codex from FritzAndFriends/BlazorWebFormsComponents. It costs 136 tokens per session (2,456 once invoked), scanned A, original, MIT.

An end-to-end benchmark for converting the WingtipToys sample, an ASP.NET Web Forms application, into a new application and checking it with browser tests. Each run starts with the original sample and records a numbered report with screenshots.

In plain words
What is it for?
Use it to run the WingtipToys migration, repair only the newly generated result, run the existing Playwright acceptance tests, and document the outcome.
Why use it?
It measures the migration process from a clean starting point and prevents earlier output or fixes from hiding problems in the current run.

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

wingtip-migration-test 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 4d 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.

WingtipToys Migration Test

End-to-end migration benchmark for the canonical WingtipToys Web Forms sample. This workflow uses the repository's migration toolkit as the public entry point, preserves the migrated application shape in samples\AfterWingtipToys\, and considers the run successful only when the existing Playwright acceptance tests pass.

Benchmark Integrity Rules

This workflow is a benchmark, so every run must start from scratch.

Required behavior

  1. Start with the raw Web Forms source in samples\WingtipToys\.
  2. Clear samples\AfterWingtipToys\ before each run.
  3. Run migration-toolkit\scripts\bwfc-migrate.ps1 to produce the output for this run.
  4. Repair only the fresh output produced during the current run.

Forbidden behavior

  1. Do not restore or copy previously migrated content into samples\AfterWingtipToys\.
  2. Do not use git history as migration input or repair content:
    • no git restore
    • no git checkout
    • no git show to pull old file contents into the run
    • no copying files from prior commits, branches, tags, or stashes
  3. Do not reuse prior benchmark outputs from:
    • samples\AfterWingtipToys\
    • dev-docs\migration-tests\wingtiptoys\run*
    • session artifacts, temp folders, or prior migration snapshots
  4. Do not treat an earlier repaired sample as the answer. The point of the run is to measure what the toolkit plus current repair work can achieve from scratch.

If a run uses prior migrated content or git-sourced repairs, the benchmark is invalid and must be restarted from a freshly cleared output folder.

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.
