Thinking Beast Mode A transcendent coding agent with quantum cognitive architecture, adversarial intelligence, and unrestricted creative freedom. threat model analyst Full STRIDE-A threat model analysis and incremental update skill for repositories and systems. Supports two modes: (1) Single analysis — full STRIDE-A threat model of a repository, producing architecture overviews, DFD diagrams, STRIDE-A analysis, prioritized findings, and executive assessments. (2) Incremental analysis — takes a previous threat model report as baseline, compares the codebase at t tiny stepping Incremental development workflow that makes the smallest meaningful change per step and pauses for feedback, so the direction gets validated early before continuing. Use for careful, iterative implementation with continuous validation. tldr prompt Create tldr summaries for GitHub Copilot files (prompts, agents, instructions, collections), MCP servers, or documentation from URLs and queries. tm7 threat model Creates valid Microsoft Threat Modeling Tool (.tm7) files compatible with the Microsoft Threat Modeling Tool v7.3+. Use this skill whenever asked to create, generate, or modify a .tm7 threat model file, or when performing STRIDE threat modeling that should output a .tm7 file that opens cleanly in the Microsoft Threat Modeling Tool. transloadit media processing Process media files (video, audio, images, documents) using Transloadit. Use when asked to encode video to HLS/MP4, generate thumbnails, resize or watermark images, extract audio, concatenate clips, add subtitles, OCR documents, or run any media processing pipeline. Covers 86+ processing robots for file transformation at scale. Trojan Skill Hunter Audits agent, skill, instruction, hook, and MCP-config contributions for hidden prompt injection, tool poisoning, unicode steganography, and excessive-agency red flags before they are merged, installed, or trusted — mapped to the OWASP Top 10 for LLM Applications and real-world MCP attack research.

Supports full-page captures, interactive states, and an iterate-on-crop workflow that avoids slow re-screenshots. Ultimate Transparent Thinking Beast Mode Ultimate Transparent Thinking Beast Mode unit test vue pinia Write and review unit tests for Vue 3 + TypeScript + Vitest + Pinia codebases. Use when creating or updating tests for components, composables, and stores; mocking Pinia with createTestingPinia; applying Vue Test Utils patterns; and enforcing black-box assertions over implementation details. Universal Janitor Perform janitorial tasks on any codebase including cleanup, simplification, and tech debt remediation. Universal PR Comment Addresser Address PR comments update avm modules in bicep Update Azure Verified Modules (AVM) to latest versions in Bicep files. update implementation plan Update an existing implementation plan file with new or update requirements to provide new features, refactoring existing code or upgrading packages, design, architecture or infrastructure. update llms Update the llms.txt file in the root folder to reflect changes in documentation or specifications following the llms.txt specification at https://llmstxt.org/ update markdown file index Update a markdown file section with an index/table of files from a specified folder. update specification Update an existing specification file for the solution, optimized for Generative AI consumption based on new requirements or updates to any existing code. vardoger analyze Use when the user asks to personalize the GitHub Copilot CLI assistant, adapt Copilot to their style, use vardoger, or analyze their Copilot CLI conversation history. Reads the local session directory at `~/.copilot/session-state/`, extracts recurring preferences and conventions, and writes a fenced personalization block into `~/.copilot/copilot-instructions.md`.
