Formal evaluation framework for Claude Code sessions implementing eval-driven development (EDD) principles

Provides context about the Roo Code evals system structure in this monorepo. Use when tasks mention "evals", "evaluation", "eval runs", "eval exercises", or working with the evals infrastructure. Helps distinguish between the evals execution system (packages/evals, apps/web-evals) and the public website evals display page (apps/web-roo-code/src/app/evals).

Evaluates LLMs across 60+ academic benchmarks (MMLU, HumanEval, GSM8K, TruthfulQA, HellaSwag). Use when benchmarking model quality, comparing models, reporting academic results, or tracking training progress. Industry standard used by EleutherAI, HuggingFace, and major labs. Supports HuggingFace, vLLM, APIs.

Expert guidance for building reliable event-driven architectures with Inngest - serverless background jobs, durable workflows, and step-based execution without managing infrastructure.

Design and implement event stores for event-sourced systems. Use when building event sourcing infrastructure, choosing event store technologies, or implementing event persistence patterns.

This skill should be used when reviewing or editing copy to ensure adherence to Every's style guide. It provides a systematic line-by-line review process for grammar, punctuation, mechanics, and style guide compliance.

Systematic framework for synthesizing research evidence across multiple sources, applying hierarchical quality standards to generate authoritative summaries and identify knowledge consensus.

Comprehensive monitoring solution for EVM blockchain networks with integrated security and telemetry capabilities. Monitors gas prices, transaction throughput, and network health across multiple chains.

Advanced EVM bytecode analysis for decompilation, vulnerability detection, and gas pattern profiling across Ethereum and EVM-compatible chains.

Use this skill when the user asks "gas price", "how much is gas", "current gas", "check gas fees", or mentions checking gas costs on EVM chains (Ethereum, Polygon, Arbitrum, etc.). Optional chain parameter.

Use when the user mentions Exa research OR when the workflow benefits from complex, multi-step research and other exa-ai approaches are not yielding satisfactory results.

Semantic search, similar content discovery, and structured research using Exa API

Semantic search, similar content discovery, and structured research using Exa API

Use when tasks involve creating, editing, analyzing, or formatting spreadsheets (`.xlsx`, `.csv`, `.tsv`) using Python (`openpyxl`, `pandas`), especially when formulas, references, and formatting need to be preserved and verified.

Create leveraged buyout (LBO) models in Excel with sources & uses, debt schedules, cash flow waterfalls, and IRR calculations for private equity analysis Activates when you request "excel lbo modeler" functionality.

Build leveraged buyout (LBO) models in Excel with debt schedules and IRR analysis. Use when structuring LBO transactions or analyzing PE returns. Trigger with phrases like 'excel lbo', 'build lbo model', 'calculate pe returns'.

Plans, creates, and optimizes marketing campaigns including content strategy, social media, email, and analytics. Helps develop go-to-market strategies, campaign messaging, and performance measurement.

Use when you have a written implementation plan to execute in a separate session with review checkpoints

Designs deliberate practice exercises applying evidence-based learning strategies like retrieval practice, spaced repetition, and interleaving. Activate when educators need varied exercise types (fill-in-blank, debug-this, build-from-scratch, extend-code, AI-collaborative) targeting learning objectives with appropriate difficulty progression. Creates exercise sets that apply cognitive science principles to maximize retention and skill development. Use when designing practice activities for Py...

Explicit Identity Across Boundaries

This skill should be used when the user asks to "run pentest commands", "scan with nmap", "use metasploit exploits", "crack passwords with hydra or john", "scan web vulnerabilities with nikto", "enumerate networks", or needs essential penetration testing command references.

Use this skill when building secure authentication systems, validating input handlers, reviewing API endpoints, managing secrets, or implementing payment/sensitive features. Delivers comprehensive security analysis with detailed vulnerability assessment.

Perform comprehensive exploratory data analysis on scientific data files across 200+ file formats. This skill should be used when analyzing any scientific data file to understand its structure, content, quality, and characteristics. Automatically detects file type and generates detailed markdown reports with format-specific analysis, quality metrics, and downstream analysis recommendations. Covers chemistry, bioinformatics, microscopy, spectroscopy, proteomics, metabolomics, and general scien...
