Token-efficient app development agent using /serena command for structured problem-solving. Specializes in full-stack implementation (components, APIs, systems, tests) with maximum token efficiency. Use proactively when /serena command is explicitly requested or when token-efficient structured development is needed for complex multi-step implementations.

AWS cloud specialized Tachikoma execution agent. Handles Lambda, API Gateway, DynamoDB, CDK, EKS, S3, Bedrock, and all AWS services including security (IAM, KMS, GuardDuty), cost optimization, and SRE operations. Use proactively when working with AWS services, CDK infrastructure, serverless applications, or AWS-related code. Detects: cdk.json, samconfig.toml, serverless.yml, @aws-sdk in package.json, or boto3 in Python deps.

Google Cloud specialized Tachikoma execution agent. Handles Cloud Run (serverless deployment), BigQuery (SQL analytics, advanced operations, ML), GCP security (IAM, VPC, KMS, Zero Trust, DevSecOps), data engineering (pipelines, governance, lakehouse/BigLake/Dataplex, ingestion, real-time analytics), networking (VPC, LB, CDN, hybrid), Memorystore (Redis/Memcached), enterprise architecture (account design, migration), compute selection (GCE/GKE/GAE/Run/Functions), GKE orchestration, monitoring design, BI visualization (Looker), workflow orchestration (Composer/Dataform), and ML analytics (Vertex AI, BigQuery ML). Use proactively when working with Google Cloud services, GCP infrastructure, or cloud-native applications on GCP. Detects: cloudbuild.yaml, .gcloudignore, @google-cloud packages, Looker, Dataplex.

Infrastructure/DevOps specialized Tachikoma execution agent. Handles Docker/Podman containers, Compose orchestration, CI/CD pipeline configuration, and DevOps methodology. Use proactively when working with Dockerfiles, Containerfiles, docker-compose.yml, CI/CD configs, or implementing DevOps practices. Detects: Dockerfile, Containerfile, docker-compose.*, or podman-related files.

Terraform IaC specialized Tachikoma execution agent. Handles HCL configuration, module design, state management, Terragrunt wrapper patterns, infrastructure testing, and cloud provider resources. Use proactively when working with .tf files, terragrunt.hcl, or infrastructure as code definitions. Detects: .tf files or terragrunt.hcl.

Clean Architecture and Domain-Driven Design (DDD) unified guide covering the Dependency Rule, concentric layer model (Entities, Use Cases, Interface Adapters, Frameworks & Drivers), component principles (REP/CCP/CRP, ADP/SDP/SAP), Screaming Architecture, Humble Objects, and DDD strategic/tactical patterns (Bounded Context, Ubiquitous Language, Context Mapping, Value Object, Entity, Aggregate, Event Sourcing, CQRS, Saga, data decomposition). Use when designing application layer structure, enforcing dependency rules, separating business logic from frameworks/UI/databases, modeling complex domains with DDD patterns, or mapping Bounded Contexts to Clean Architecture layers. For code-level clean practices, use writing-clean-code. For distributed/infrastructure patterns, use cloud:architecting-infrastructure. For evolutionary architecture and microservices intro, see ARCHITECTURE-EVOLUTION.md. For project foundations and team practices, use practicing-software-engineering.

Semantic Versioning 2.0.0仕様に基づくバージョン判断ガイド。MAJOR/MINOR/PATCH判定、プレリリース・ビルドメタデータ、範囲指定を提供。 REQUIRED for all version-related decisions. Use when determining version bumps, creating releases, or managing dependencies. For commit message format (type/scope/BREAKING CHANGE), use writing-conventional-commits instead.

Claude Code Plugin (Agent / Skill / Command) authoring guide. Use when creating, modifying, or reviewing plugin components. Includes Agent Skills standard (agentskills.io) + Claude Code extensions, context: fork applicability matrix, name/description constraint validation, and spec-freshness checks.

Allows you to view the user's screen as well as several hours of history. Use when the user makes a reference to their recent work, for which it'd be helpful to see the screen. This skill MUST be used whenever you need to resolve ambiguity in a user request, where the user hasn't specified enough context to do the task. Examples include disambiguating the specific user/app/document/error the user is referring to. You must also use this skill if the user asks about any question regarding Chronicle or asks what you can see from the screen.

Claude Code Agent定義（.md）をCodex subagent定義（agents/*.toml）に変換するガイド。 フィールドマッピング・developer_instructions変換・skillsのdescription自動ロード方式・検証手順・よくある失敗パターンを網羅。 Use when converting Claude Code agents to Codex format, migrating agent definitions, or setting up Codex subagents. Triggers: "agentをcodexに変換", "codex agent変換", "agent migration"。
