宣言型パッケージ設定で最小限のOCIイメージを組み立てる（apko）

apkoを使って宣言型パッケージマニフェストから最小限のOCIイメージを構築し、サプライチェーンの明確さとコンテンツの最小性が従来のDockerfileフローよりも重要な場合に使用します。

宣言型パッケージ設定で最小限のOCIイメージを組み立てる（apko） とは？

このスキルは、apkoツールを使用して宣言型パッケージ設定から最小限のOCI（Open Container Initiative）イメージを構築する方法を提供します。apkoは、Dockerfileのような命令型のアプローチではなく、YAMLベースの宣言型マニフェストを使用することで、ビルドの再現性とサプライチェーンの透明性を重視しています。このスキルの主な利点は、ビルドがデフォルトで完全に再現可能であること、s6監視スイートをサポートして複数プロセスを実行できること、そして生成されるイメージが非常に小さく、必要最小限のパッケージのみを含むことです。対応プラットフォームは、macOS（Homebrew）、Go環境、Dockerです。使用方法は、apkoをインストールし、パッケージマニフェスト（YAMLファイル）を用意して、`apko build`コマンドを実行するだけです。このスキルは、セキュリティと透明性が重要な環境や、イメージサイズを極限まで削減したい場合に特に有用です。

apkoで宣言型パッケージ設定から最小限のOCIイメージを組み立てる

apkoを使って宣言型パッケージマニフェストから最小限のOCIイメージを構築します。サプライチェーンの明確さとコンテンツの最小性が従来のDockerfileフローよりも重要な場合に使用します。

前提条件

apkoと、使用を予定しているパッケージソースおよびOCI出力先へのアクセスが必要です。

インストール

環境に合ったアップストリームのインストール方法またはセットアップパスを使用してください。

  • brew install apko
  • go install chainguard.dev/apko@latest
  • docker run cgr.dev/chainguard/apko version
  • docker run -v "$PWD":/work cgr.dev/chainguard/apko build examples/alpine-base.yaml apko-alpine:edge apko-alpine.tar

アップストリームからの要件と注意事項:

  • または、Dockerを使用する場合:
  • 生成されたtarイメージをDocker環境にロードできます:

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

Academic Paper Citation Network Mapper

Builds citation networks from Semantic Scholar API and CrossRef DOI metadata. Visualizes paper influence graphs using NetworkX, identifies seminal works, and tracks research lineage across fields.

ACF Custom Fields REST Exposer

Exposes Advanced Custom Fields data through the WordPress REST API using register_rest_field and acf_format_value. Handles repeater fields, flexible content layouts, and gallery fields with proper serialization.

ACF Extended for Advanced Custom Fields Workflows

An ASE skill built around ACF Extended, the WordPress enhancement suite for Advanced Custom Fields that adds field types, admin improvements, front-end forms, options pages, and developer tooling. It is a practical fit for agents working inside complex WordPress content models and custom field workflows.

ACF to Gutenberg Block Migrator

Converts Advanced Custom Fields field groups into native Gutenberg blocks using the ACF Block API v2 and @wordpress/scripts build pipeline. Maps ACF repeaters, groups, and flexible content to InnerBlocks and block attributes with server-side rendering via acf_register_block_type().

Activepieces Open Source Workflow Automation

Activepieces is an open-source, self-hostable workflow automation platform with 200+ integrations. It provides a visual builder for creating automated workflows and exposes all its connectors as MCP servers for AI agent use.

ActivityWatch Cross-Platform Automated Time Tracker and Producti

ActivityWatch is a privacy-first, open-source automated time tracker that records application usage, browser activity, and AFK status across Windows, macOS, and Linux. With 16k+ GitHub stars, it provides detailed productivity analytics without sending data to external servers.

act Local GitHub Actions Runner

act is an open-source CLI tool that runs GitHub Actions workflows locally using Docker, enabling fast feedback on workflow changes without pushing to GitHub. It is a standard tool for local Actions development and testing.

Add a browser review checkpoint before risky agent actions with

Use AgentClick when an agent should pause before risky commands, plans, drafts, or code changes so a human can inspect, edit, approve, or reject them in a purpose-built browser UI.

Add Claude design-system and accessibility workflows with UX/UI

Use UX/UI Agent Skills when Claude should generate tokens, component specs, accessibility audits, and framework-specific UI code from a repeatable design workflow.

Add executable smoke tests for shell scripts and CLIs before ref

Use Bats-core when an agent needs to turn fragile shell scripts or command-line workflows into something it can verify repeatedly after edits. The agent writes focused Bash tests for success paths, failure paths, and output contracts, then runs them locally or in CI before a refactor, release, or incident fix goes out.

Add graph-backed memory and context retrieval to agent workflows

Use Cognee to ingest project knowledge into graph and vector memory so agents can retrieve durable context across sessions and workflows.

Add IDE-style semantic code navigation and symbol-safe refactors

Give a coding agent symbol-aware lookup, cross-file rename, and structural edit tools before it starts making brittle text-only changes.

Add managed long-term memory to LangGraph agents with LangMem

Give LangGraph agents memory management and search tools so they can store, retrieve, and update durable facts across sessions.

Add multimodal lifelong memory to MCP and Python agents with Sim

Use SimpleMem to store, compress, index, and retrieve text or multimodal memories for agents through MCP or Python integrations.

Add persistent project memory and hook-driven synthesis with Cla

Keep Claude Code sessions grounded in prior decisions, project context, and daily handoff notes instead of starting from zero every time.

Add Postgres-native vector retrieval to agent and RAG workflows

Store embeddings beside application data in Postgres, create vector indexes, and query nearest neighbors for semantic search, RAG, recommendations, or agent memory retrieval.

Address GitHub PR review comments from the current branch with g

Find the open PR for the current branch, gather unresolved review comments, and drive a focused comment-resolution workflow with gh-authenticated context.

Add runtime guardrails to TypeScript agents with VoltAgent

Use VoltAgent to intercept, validate, and enforce input/output policies in TypeScript agent workflows.

Add temporal context memory to agent workflows with Zep

Use Zep as an external context layer for agents that need to store events, assemble temporal graph context, and retrieve relevant memory before model calls.
