Excel Data Analyzer

Analyze code complexity, cyclomatic complexity, maintainability index, and code churn using metrics tools. Use when assessing code quality, identifying refactoring candidates, or monitoring technical debt.

Process account maintenance requests across the account lifecycle. Use when changing a client address or contact info with identity verification, updating beneficiary designations after marriage, divorce, birth, or death, re-registering or re-titling an account to a trust or new entity, selecting tax lot methods or fixing cost basis records, applying legal or compliance holds or Reg T freezes, setting up systematic withdrawals or standing instructions, processing a death notification and estate account setup, handling a QDRO, power of attorney, or guardianship, closing accounts and managing escheatment, or designing data quality review programs.

Core bioinformatics concepts including SAM/BAM format, AGP genome assembly format, sequencing technologies (Hi-C, HiFi, Illumina), quality metrics, and common data processing patterns. Essential for debugging alignment, filtering, pairing issues, and AGP coordinate validation.

Expert bash/shell scripting across environments where Bash is available (Linux, macOS, Git Bash on Windows, WSL, containers). This is a Bash-focused skill - it does not provide PowerShell parity; on Windows the target is the Bash interpreter (Git Bash / WSL), not native PowerShell. PROACTIVELY activate for: (1) ANY bash/shell script task, (2) System automation, (3) DevOps/CI/CD scripts, (4) Build/deployment automation, (5) Script review/debugging, (6) Converting commands to scripts. Provides: Google Shell Style Guide compliance, ShellCheck validation, Bash portability across Linux/macOS/WSL/Git Bash/containers, POSIX compliance, security hardening, error handling, performance optimization, testing with BATS, and production-ready patterns. Ensures professional-grade, secure, portable Bash scripts every time.

Architectural audit that hunts dead code, duplicated functionality, anti-patterns, type confusion, and code smells across a whole codebase. Use when the user asks for architectural analysis, to find dead or unused code, identify duplication, or assess codebase health. Don't use for style/formatting, performance profiling, security audits, or feature-level code review.

Audits, scores, and refactors AGENTS.md and CLAUDE.md agent instruction files using execution-first standards: working commands, real-failure gotchas, signal-to-noise, and @import progressive disclosure. Runs a 12-check quick triage or a 49-check full audit with letter grades, then proposes minimal diffs. Use when asked to audit, review, score, refactor, or improve agent instruction files, fix stale commands, reduce bloat, write a new AGENTS.md, or when asking "my AGENTS.md is bad", "help me write a CLAUDE.md", or "improve my agent instructions". For SKILL.md skill files use agent-skills-creator; for general docs use docs-writing; for mining session history into instruction suggestions use the external cadence-advise skill where installed.
