ci-pipeline-synthesizerGenerate GitHub Actions CI/CD pipeline configurations for automated building and testing of library and package projects.
CI Pipeline Synthesizer is an agent skill from kajisho5/ffmpeg-skill. Generate GitHub Actions CI/CD pipeline configurations for automated building and testing of library and package projects. Use when creating or updating CI workflows for npm packages, Python packages, Go modules, Rust crates, or other library projects that need automated build and test pipelines. Includes templates for common package ecosystems with best practices for dependency caching, matrix testing, and artifact publishing.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including assets (for example `assets/github-actions-go.yml`, `assets/github-actions-nodejs.yml` and `assets/github-actions-python.yml`).
It sits in DevOps & Cloud, covering CI/CD and Caching. It works with GitHub Actions, Rust, npm and Python. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 1f7e7e3. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
npmpythongocargoFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
github.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
CI Pipeline Synthesizer loads about 1.1k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 438 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.
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.

This skill also uses 4 other files; get the full folder from GitHub.Generate production-ready GitHub Actions workflow files for library and package projects with automated build and test stages, dependency caching, and multi-version testing matrices.
Determine the package ecosystem by examining project files:
package.json presentsetup.py, pyproject.toml, or requirements.txt presentgo.mod presentCargo.toml presentUse the appropriate template from assets/ based on project type:
github-actions-nodejs.yml - Node.js/npm packagesgithub-actions-python.yml - Python packagesgithub-actions-go.yml - Go modulesgithub-actions-rust.yml - Rust cratesAdapt the template to project-specific needs:
Test commands: Update test scripts to match project conventions
npm test, npm run test:coveragepytest, python -m unittestgo test ./...cargo testBuild commands: Adjust build steps if needed
npm run build (if build step exists)python -m buildgo buildcargo build --releaseVersion matrix: Modify tested versions based on support policy
Trigger conditions: Adjust when pipeline runs
Create the workflow file at .github/workflows/ci.yml in the project root. If .github/workflows/ doesn't exist, create the directory structure first.
Check that the generated workflow:

(pip/npm/go/cargo). They do NOT model this repo's actual CI needs — installing
a real ffmpeg binary per OS (apt/brew ffmpeg-full/choco), capturing its
-filters/-encoders/-bsfs listings as an artifact, or the skipIf-based
Windows test coverage in tests/test_contract.py — all of which
.github/workflows/ci.yml already handles and this skill's templates would
not reproduce. Treat this as reference/scaffolding for a plain Python/Node/Go/
Rust package elsewhere, not a drop-in replacement for this repo's own
workflow.

Generate GitHub Actions CI/CD pipeline configurations for automated building and testing of library and package projects. CI Pipeline Synthesizer is an agent skill from kajisho5/ffmpeg-skill. Generate GitHub Actions CI/CD pipeline configurations for automated building and testing of library and package projects.
CI Pipeline Synthesizer fits situations like: updating CI workflows for npm packages; Python packages; other library projects that need automated build and test pipelines.
Run `npx skills add kajisho5/ffmpeg-skill --skill ci-pipeline-synthesizer -a claude-code`. Or copy the skill folder (.claude/skills/ci-pipeline-synthesizer in kajisho5/ffmpeg-skill) into .claude/skills/ci-pipeline-synthesizer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add kajisho5/ffmpeg-skill --skill ci-pipeline-synthesizer -a codex`. Or copy the skill folder (.claude/skills/ci-pipeline-synthesizer in kajisho5/ffmpeg-skill) into .agents/skills/ci-pipeline-synthesizer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add kajisho5/ffmpeg-skill --skill ci-pipeline-synthesizer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ci-pipeline-synthesizer, .gemini/skills/ci-pipeline-synthesizer, .github/skills/ci-pipeline-synthesizer and .opencode/skills/ci-pipeline-synthesizer in your project.
Going by SKILL.md and its folder, CI Pipeline Synthesizer needs the command-line tools its instructions call (npm, python, go and cargo). Our summary lists: Python 3; Node.js.
SKILL.md names 1 domain. In commands or code: github.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
CI Pipeline Synthesizer is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
