What it does
Swig CI Repro is an agent skill from swig/swig. Reproduce a GitHub Actions Linux CI failure locally when it does not happen on your machine: a podman/docker image that mirrors the ubuntu-22.04 runner by reusing the real Tools/CI-linux-.sh install scripts, parameterised by target language and version. Covers the helper Tools/ci-repro/run.sh, the act fallback, and a worked Ruby 3.3 example.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in DevOps & Cloud, covering CI/CD, Failing and flaky tests and Containers. It works with Linux, Ruby, GitHub Actions and Docker. 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
- Tasks that involve CI/CD
- Tasks that involve Failing and flaky tests
- Tasks that involve Containers
Example prompts
- “/swig-ci-repro”
Requirements
- Python 3
- Docker
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
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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 CI Repro loads about 1.2k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 488 words of instructions outside code blocks.
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 488 words (~1,206 tokens).
“package differs from what CI builds - e.g. CI builds Ruby 3.3 from source via RVM, apt ships 3.2).”
- name
- swig-ci-repro
- argument-hint
- Optionally specify the failing language and version, e.g. ruby 3.3
