Install the architecture-patterns skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description. 

git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter
mkdir -p ~/.claude/skills
cp -r /tmp/babysitter/library/methodologies/cc10x/skills/architecture-patterns ~/.claude/skills/architecture-patterns
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

The instructions your agent would load

SKILL.md as published, without the frontmatter. Read it on GitHub

  • Single responsibility boundaries
  • Interface contracts and type safety
  • Dependency injection patterns
  • Module cohesion and coupling analysis

Data Flow

  • Request/response patterns
  • Event-driven architecture
  • State management strategies
  • Data transformation pipelines

Integration Patterns

  • API design (REST, GraphQL, RPC)
  • Message queuing and async processing
  • Service boundaries and communication
  • Error propagation across boundaries

Scalability

  • Horizontal vs vertical scaling considerations
  • Caching strategies
  • Database design and query optimization
  • Load balancing and distribution

Decision Checkpoints

Architectural decisions require user approval when:

  • Introducing new service boundaries
  • Changing data flow patterns
  • Adding new external dependencies
  • Modifying public API contracts

When to Use

  • During PLAN workflow architecture phases
  • During BUILD when architectural choices arise
  • When reviewing system design in REVIEW workflow

Agents Used

  • planner (architecture planning)
  • component-builder (architecture implementation)
  • code-reviewer (architecture review)

  • Aagent-boosterWASM-based instant code transforms for simple tasks, achieving 352x speedup over LLM inference with zero cost.
  • Aagent-coordinationCoordinate Crew (persistent) and Polecat (transient) agents using Gas Town's hook-based work distribution and GUPP principle.
  • Aagent-dispatch
  • Aanti-driftHierarchical coordination and drift detection with frequent checkpoints, shared memory coherence validation, role specialization enforcement, and short task cycles.
  • Aarchitecture-design
  • Aassimilate-popular-workflowsThis skill should be used when the user asks to "find skills in the wild", "assimilate popular workflows", "discover SKILL.md files in repos", "research external skills", "find workflow patterns", "survey the skill landscape", "what skills exist out there", or wants to investigate public repositories for extractable processes, babysitter plugins, and reusable procedural insights. Searches GitHub for SKILL.md files, classifies repos by archetype, and maintains structured research under docs/reference-repos/.
  • Aaudit-trail
  • AbabysitOrchestrate via @babysitter. Use this skill when asked to babysit a run, orchestrate a process or whenever it is called explicitly. (babysit, babysitter, orchestrate, orchestrate a run, workflow, etc.)
  • Ababysit-babysitter-issuesThis skill should be used when the user asks to "babysit issues", "work on assigned issues", "check a5c-agent issues", "process babysitter issues", or wants to find and work on open GitHub issues assigned to a5c-agent in the babysitter repo.
  • Abehavior-contractBug condition/postcondition formalization as testable Behavior Contracts. Defines invariants that must be preserved across fixes.
  • AbrainstormingClarify vague requirements through exploratory questioning and option generation before committing to research or implementation.
