Essentials

Essential tooling for discovering docs, cleaning up code, deep thinking (ultraplan), and systematic code review.

Features:

#### UltraPlan - Deep Investigation Methodology

Systematic multi-step investigation of complex problems with confidence-based progression.

```bash

/ultraplan I need help designing a better architecture for...

```

What it does:

• Progressive confidence tracking (exploring → low → medium → high → certain)
• Multi-step investigation with state accumulation
• Iterative Haiku agent guidance for next-step suggestions
• Final Sonnet agent validation for comprehensive analysis
• Practical engineering focus with trade-off analysis
• Implementation options with pros/cons (similar to Claude Code plan mode)

#### CodeReview - Systematic Code Analysis

Multi-step code review with severity-classified findings and actionable fixes.

```bash

/codereview src/auth.py src/middleware.py

```

What it does:

• Progressive confidence tracking (exploring → low → medium → high → certain)
• Severity classification for all issues (🔴 CRITICAL, 🟠 HIGH, 🟡 MEDIUM, 🟢 LOW)
• Multi-step investigation with state accumulation
• Iterative Haiku agent guidance for coverage validation
• Final Sonnet agent validation for independent review
• Actionable fixes with before/after code examples
• Top 3 priorities with effort estimates
• Quick wins vs. long-term improvements

Focus areas:

• Security vulnerabilities (SQL injection, XSS, hardcoded secrets, auth gaps)
• Concurrency issues (race conditions, deadlocks, thread-safety)
• Resource management (memory leaks, unclosed connections)
• Error handling gaps
• Performance bottlenecks (algorithmic complexity, N+1 queries)
• Code quality and maintainability

Best for:

• Security audits before production
• Bug investigation and root cause analysis
• Performance bottleneck identification
• Code quality assessment
• Pre-deployment validation

#### Documentation Lookup Skill

Fetches library documentation via Context7's HTTP API using the "code execution" pattern.

What it does:

• Proactively activates when you mention libraries or frameworks
• Writes curl commands to fetch documentation from Context7 API
• Two-step process: search for library ID, then fetch docs
• Falls back to web search if needed
• Use: "Check the docs for..."

Why code execution? Instead of always loading MCP tool definitions into context, Claude writes API calls only when needed—reducing context usage and demonstrating the pattern from [Anthropic's code execution blog post](https://www.anthropic.com/engineering/code-execution-with-mcp).

#### Code Examples Skill

Find real-world code examples across millions of GitHub repositories using [grep.app](https://grep.app).

What it does:

• Finds how others implement specific patterns in production code
• Filters by language, repository, or file path
• Use: "How do others implement X?" or "Show me usage examples for..."

Complements documentation-lookup: While documentation-lookup fetches official docs, code-examples finds real-world usage in production code.

#### Code Janitor Agent

Mechanical code maintenance specialist for tedious cleanup work.

What it does:

• Fixes linting errors systematically
• Renames variables consistently across files
• Updates import statements
• Fixes formatting issues
• Iterates until all fixable issues are resolved

#### Consensus - Multi-Perspective Decision Analysis

Analyze complex decisions from multiple viewpoints using specialized debate agents.

```bash

/consens
