Plan and execute language-to-language server or application migrations with behavior parity.

  • Works in 6 steps: Scope the migration boundary → Generate oracles → Generate migrated tests → …
  • Porting modules
  • SKILL.md covers Core Rules, Workflow, Release Gates and Reporting Template
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Translate Programming Language is an agent skill from mizchi/skills. Plan and execute language-to-language server or application migrations with behavior parity. Use when porting modules, services, APIs, or runtimes between programming languages; generating source-runtime oracles and fixtures; generating migrated parity tests; detecting runtime, standard-library, serialization, numeric, encoding, time, regex, or protocol differences; building temporary compatibility layers; accumulating migration knowledge; benchmarking; shadow testing; canarying; or planning cutover and rollback.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `README.md`, `SKILL-ja.md` and `agents/openai.yaml`).

It sits in DevOps & Cloud. The repository describes itself as: Agent skills by mizchi, distributed via APM.

When your agent uses it

  • Porting modules
  • Runtimes between programming languages
  • Generating source-runtime oracles and fixtures
  • Generating migrated parity tests

Example prompts

  • “/translate-programming-language”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Scope the migration boundary
  2. Generate oracles
  3. Generate migrated tests
  4. Accumulate migration knowledge
  5. Port domain code
  6. Verify in real environments and switch

What it can do on your machine

Read from SKILL.md and the folder at commit 62f5808. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Translate Programming Language loads about 1.4k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 137 tokens; SKILL.md has 536 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~137
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 536 words (~1,398 tokens).

“Use this skill to migrate production server/application code from one language/runtime to another without losing externally observable behavior. Preserve parity first, then simplify toward the target language after the old runtime is removed.”
