What it does

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.

When your agent uses it

  • Updating CI workflows for npm packages
  • Python packages
  • Other library projects that need automated build and test pipelines

Example prompts

  • “/ci-pipeline-synthesizer”

Requirements

  • Python 3
  • Node.js

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Identify Project Type
  2. Select Template
  3. Customize Configuration
  4. Place Workflow File
  5. Verify Configuration

What it can do on your machine

Read from SKILL.md and the folder at commit 1f7e7e3. 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

    Shell commands in SKILL.md call:

    • npm
    • python
    • go
    • cargo

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • 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

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.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

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.

CI Pipeline Synthesizer

Overview

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.

Workflow

1. Identify Project Type

Determine the package ecosystem by examining project files:

  • Node.js/npm: package.json present
  • Python: setup.py, pyproject.toml, or requirements.txt present
  • Go: go.mod present
  • Rust: Cargo.toml present
2. Select Template

Use the appropriate template from assets/ based on project type:

  • github-actions-nodejs.yml - Node.js/npm packages
  • github-actions-python.yml - Python packages
  • github-actions-go.yml - Go modules
  • github-actions-rust.yml - Rust crates
3. Customize Configuration

Adapt the template to project-specific needs:

Test commands: Update test scripts to match project conventions

  • Node.js: npm test, npm run test:coverage
  • Python: pytest, python -m unittest
  • Go: go test ./...
  • Rust: cargo test

Build commands: Adjust build steps if needed

  • Node.js: npm run build (if build step exists)
  • Python: python -m build
  • Go: go build
  • Rust: cargo build --release

Version matrix: Modify tested versions based on support policy

  • Node.js: LTS versions (16.x, 18.x, 20.x)
  • Python: Active versions (3.9, 3.10, 3.11, 3.12)
  • Go: Recent versions (1.21, 1.22)
  • Rust: stable, beta (optional)

Trigger conditions: Adjust when pipeline runs

  • Default: Push to main/master, all pull requests
  • Custom: Specific branches, paths, or schedules
4. Place Workflow File

Create the workflow file at .github/workflows/ci.yml in the project root. If .github/workflows/ doesn't exist, create the directory structure first.

5. Verify Configuration

Check that the generated workflow:

  • Uses appropriate actions versions (e.g., actions/checkout@v4, actions/setup-node@v4)
  • Includes dependency caching for faster builds
  • Runs on appropriate triggers (push, pull_request)
  • Tests against relevant version matrices
  • Has clear job and step names
Show full SKILL.md (186 more words)Show less

Template Features

All templates include:

  • Dependency caching: Speeds up builds by caching package managers
  • Matrix testing: Tests across multiple language/runtime versions
  • Parallel execution: Runs tests for different versions concurrently
  • Clear naming: Descriptive job and step names for easy debugging
  • Best practices: Uses recommended actions and configurations

Customization Examples

Add code coverage reporting:

yaml
- name: Upload coverage to Codecov
  uses: codecov/codecov-action@v3
  with:
    file: ./coverage.xml

Add linting step:

yaml
- name: Run linter
  run: npm run lint  # or: pylint, golangci-lint, cargo clippy

Restrict to specific branches:

yaml
on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

Add scheduled runs:

yaml
on:
  schedule:
    - cron: '0 0 * * 0'  # Weekly on Sunday

Tips

  • Start with the template and customize incrementally
  • Test the workflow by creating a pull request or pushing to a test branch
  • Use actions/cache for dependencies to reduce build times
  • Keep matrix versions current with language support policies
  • Add status badges to README.md: ![CI](https://github.com/user/repo/workflows/CI/badge.svg)

Note for this repository (ffmpeg-skill)

This skill's generic templates assume ordinary language-toolchain dependencies (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.
