Claude Skills Library

The overnight-repo-auditor is a specialized skill designed for Anthropic's Managed Agents runtime (which provides a 14.5-hour task horizon). It autonomously audits an entire codebase to identify security, performance, accessibility, dependency, and code quality issues.

Key characteristics:

• Autonomous Execution: It runs without requiring user input or confirmation.
• Resilient Reporting: It writes structured findings to disk (audit-workspace/) as it proceeds, ensuring partial results survive interruptions.
• Read-Only Safety: It does not modify, build, or execute project code (except for running read-only package audits like npm audit or pip audit).
• Scalable Architecture: It uses a multi-phase workflow involving a reconnaissance phase, parallel agent deployment, and a final compilation phase.

The job-application-optimizer skill is designed to tailor job application materials and prepare for interviews. It works by analyzing job descriptions to extract required skills, keywords, and culture signals, then scoring a candidate's profile against those requirements.

Supported Tasks

• Resume Tailoring: Rewriting summaries, experience bullets, and skills sections to match a job posting while ensuring ATS (Applicant Tracking System) compatibility.
• Cover Letter Generation: Creating customized letters that match key requirements with metrics and demonstrate company research.
• Interview Preparation: Generating technical and behavioral questions, deep-dive topics, and pre-interview checklists.
• Skills Gap Analysis: Identifying missing keywords, certifications, or experience levels required by a job description.
• Application Strategy: General guidance on applying for specific roles.

### Example Triggers
- "Optimize my resume for this job posting"
- "Write a cover letter for this position"
- "Prepare interview questions for this role"
- "Analyze this job description"
- "What skills am I missing for this job?"
- "Tailor my resume to match these requirements"

The Sub-Agent Orchestrator is designed to manage heterogeneous multi-agent pipelines where the output of one agent serves as the input for the next. It is distinct from 'Agent Army' (parallel code changes) and 'Agent Swarm' (parallel data processing) because it focuses on coordinated, dependent workflows.

Key capabilities include:

• Workflow Definition: Define roles, dependencies, and handoffs using YAML.
• Execution Models: Supports sequential chains, parallel fans, conditional routing, loops, and map-reduce.
• Reliability: Built-in support for retry logic, timeout handling, and output validation.
• Modes of Operation:
  • Run a workflow file: Executes a YAML file from a specified path.
  • Define and run inline: Converts a natural-language description into a YAML workflow (requires user approval).
  • Dry run: Parses and validates the workflow and shows an execution plan without deploying agents.
  • Inspect: Parses the YAML to produce a human-readable description and a text diagram.

The Claude Skills Library is organized into several functional categories. You can select a skill based on your specific domain or technical requirement:

• AI Agent Architecture: Tools for building, orchestrating, and managing autonomous agents (e.g., agent-army, agent-to-agent, skill-composer-studio).
• Anthropic / Claude Products: Skills optimized for specific Anthropic features like Managed Agents, MCP Connectors, or the 1M context window (e.g., overnight-repo-auditor, full-codebase-migrator).
• Claude Cowork: Folder-first workflows designed for cloud sessions and scheduled tasks (e.g., cowork-inbox-triage, cowork-expense-audit).
• Sales and Revenue: Tools for pipeline analysis, lead scoring, and closing strategies (e.g., deal-closer-playbook, pipeline-health-analyzer).
• Consulting and Professional Services: Skills for proposals, client health, and business assessments (e.g., client-proposal-generator, saas-replacement-planner).
• Engineering and DevOps: Technical skills for code review, debugging, migrations, and infrastructure (e.g., code-review-pro, database-migrator).
• Design Systems and UI: Tools for building and enforcing design tokens, motion, and accessibility (e.g., design-style-installer, accessibility-auditor).
• Security and Compliance: Audit and planning tools for GDPR, HIPAA, and penetration testing (e.g., compliance-checker, contract-analyzer).
• Marketing and Content: Skills for SEO, brand voice, and video ad generation via HyperFrames (e.g., seo-optimizer, hyperframes-ad-director).
• Strategy and Finance: Tools for market sizing, pitch decks, and financial parsing (e.g., market-sizing, financial-parser).
• Operations and People: Workflows for OKRs, hiring, and documentation (e.g., workflow-automator, technical-writer).
• Small Business Essentials: Critical tools for cash flow, profitability, and local SEO (e.g., cash-flow-forecaster, local-seo-optimizer).
