Install the code-review-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/code-review-patterns ~/.claude/skills/code-review-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

  • Injection vulnerabilities (SQL, XSS, command)
  • Authentication and authorization patterns
  • Secrets handling (no hardcoded credentials)
  • Input validation and sanitization

Quality (weight: 25%)

  • Naming conventions and consistency
  • Code structure (SRP, cohesion, coupling)
  • Error handling completeness
  • Type safety (no any escapes)

Performance (weight: 20%)

  • Algorithmic complexity (flag O(n^2) or worse)
  • Resource and memory leaks
  • Database query efficiency (N+1)
  • Caching opportunities

Maintainability (weight: 25%)

  • Documentation (JSDoc/TSDoc for public APIs)
  • Test coverage adequacy
  • Readability (function length, nesting depth)
  • Tech debt markers (TODO, FIXME)

Confidence Gating

  • Only report issues with confidence >= 80%
  • Empty catch blocks are always critical (100% confidence)
  • Classify: critical, high, medium, low
  • Include actionable remediation for each issue

Router Contract

Every review must produce: STATUS, BLOCKING, REQUIRES_REMEDIATION, issue counts.

When to Use

  • Code review step in BUILD workflow
  • Fix review in DEBUG workflow
  • Full REVIEW workflow

Agents Used

  • code-reviewer (primary consumer)
  • silent-failure-hunter (error handling dimension)

  • 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.
