AF lang-migration

AI-driven full-project language migration skill. Use this skill whenever the user wants to port, translate, or rewrite a codebase from one programming language to another — including Python→Rust, Python→Go, Python→C, Python→C++, Python→Zig, Python→Bun/TS, or any other pair. Also trigger when user mentions "精确复刻", "语言迁移", "port project", "translate codebase", "1:1 rewrite", or "language conversion". This skill enforces structural equivalence first, full asset coverage (no file skipped), persistent YAML state across sessions, and a strict no-mock verification policy with human-gated blocking.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

  • low 12 top-level sections: this looks like several domains in one skill

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality base 70; lint remarks subtract, signals add up to 100. Result: 82.

External checks

ClawHub: suspicious
The skill is a disclosed code-migration workflow, but it gives the agent broad autonomous authority to scan, write, fix, and run project code with limited user checkpoints.
