What it does

Swig Test is an agent skill from swig/swig. Run SWIG test suite for specific languages. Use when testing SWIG changes, verifying language support, debugging test failures, or running regression tests.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `test-configured-languages.sh`).

It sits in Testing & QA, covering Test generation and Failing and flaky tests. The repository describes itself as: SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages.

When your agent uses it

  • Testing SWIG changes
  • Verifying language support
  • Debugging test failures
  • Running regression tests

Example prompts

  • “/swig-test”

Requirements

  • Python 3
  • A Bash shell

Workflow steps

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

  1. Ensure SWIG is built: Run make in the root directory.
  2. Run all tests for a language: Execute make check-[language]-test-suite (e.g., make check-python-test-suite).
  3. For parallel execution: Use make -j[n] check-[language]-test-suite to speed up on multi core systems that have n cores.
  4. Review output for pass/fail status and any warnings.

What it can do on your machine

Read from SKILL.md and the folder at commit 068bf9b. 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

    Ships script files (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • make
    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

Swig Test loads about 2.3k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 1,238 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,238 words (~2,327 tokens).

“Whenever you add a new testcase or modify an existing one, the final confidence step is to run it across every configured language, not just the one or two you developed against. This applies equally to a brand new test…”
