Install the code-review-gate 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/maestro/skills/code-review-gate ~/.claude/skills/code-review-gate
available in every project

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

Code Review Gate

Capabilities

Performs architect-level code review enforcing four core principles: DRY (no unnecessary duplication), YAGNI (no speculative features), proper abstraction (correct encapsulation), and test coverage (adequate automated tests). Provides numeric quality scores and specific file:line feedback.

Tool Use Instructions

  • Use Read to examine code changes and test files
  • Use Grep to search for duplication patterns and anti-patterns
  • Use Glob to verify test file coverage
  • Use Bash to run lint, test, and coverage commands
  • Use Write to generate review reports

Process Integration

  • Used in maestro-orchestrator.js Phase 4 (Architect Code Review)
  • Used in maestro-development.js (PR Review Cycle)
  • Used in maestro-hotfix.js (Expedited Review)
  • Maps to tasks: maestro-architect-code-review, maestro-dev-architect-review, maestro-hotfix-review
  • Agents: Architect, Code Reviewer
  • Quality convergence loop: rejected code returns to coder for fixes
  • Checks are "turned up to 11" by default

  • 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.
