Loads documents fully into the main agent's context so the agent can answer questions, summarize, or work with that content in subsequent turns. Use whenever the user wants to ingest, read, study, review, absorb, or pull in documents — especially when they say things like "load these docs", "read all of these", "ingest this folder", "pull in these PDFs", "load all docs in X", or paste a list of file paths/URLs and ask you to read them. Handles local files (text, code, markdown, PDFs, notebooks, images), entire folders (recursively), and remote URLs. The skill is single-turn — once the agent reports "DONE", it deactivates until the user invokes it again.
Convert EPUB books to high-quality formatted Markdown using pandoc and AI-assisted formatting. Use when the user provides an EPUB file path and wants to convert it to professionally formatted Markdown, similar to the Clean Code Collection formatting. This skill handles the complete workflow from EPUB extraction through AI-driven content formatting, including fixing PDF conversion artifacts, joining split paragraphs, correcting code blocks, standardizing headers, and creating proper Table of Contents.
Set up and configure Google's release-please for automated versioning, changelog generation, and publishing via GitHub Actions. Covers pipeline creation, Conventional Commits formatting, pre-release workflows, monorepo configuration, and troubleshooting release pipelines. Use this skill whenever the user wants to automate releases, set up CI/CD for publishing, configure version bumping, write release-please-compatible commit messages, tag versions automatically, publish to npm/PyPI/crates.io/Maven/Docker, or troubleshoot why a release PR wasn't created. Activate even if the user doesn't mention "release-please" by name — phrases like "automate my npm releases", "set up GitHub Actions for publishing", "how do I tag versions automatically", "changelog generation", "semver automation", or "pre-release workflow" all indicate this skill. For commit message guidance specifically, this skill focuses on release-please-compatible conventions; for broader multi-repo git operations with submodules, defer to multi-repo-git-ops instead.
Designs system architecture, selects tech stacks, defines components and interfaces, addresses non-functional requirements. Trigger words - architecture, system design, tech stack, components, scalability, security, API design, data model, NFR, patterns, microservices, monolith
Create Claude skills from book content (markdown files). Transforms long-form book knowledge into structured, context-efficient skill packages with granular reference files, workflows, and use-case guidelines. Use this skill when: - Converting a book (markdown) into a reusable Claude skill - Creating knowledge bases from technical books, guides, or documentation - Building skills that need progressive disclosure of large content - Structuring book knowledge for efficient context loading
Expert guidance for writing C (C99/C11) and C++ (C++17) code for embedded systems and microcontrollers. Use this skill whenever the user is working with: STM32, ESP32, Arduino, PIC, AVR, nRF52, or any other MCU; FreeRTOS, Zephyr, ThreadX, or any RTOS; bare-metal firmware; hardware registers, DMA, interrupts, or memory-mapped I/O; memory pools, allocators, or fixed-size buffers; MISRA C or MISRA C++ compliance; smart pointers or RAII in embedded contexts; stack vs heap decisions; placement new; volatile correctness; alignment and struct packing; C99/C11 patterns; C and C++ interoperability; debugging firmware crashes, HardFaults, stack overflows, or heap corruption; firmware architecture decisions (superloop vs RTOS vs event-driven); low-power modes (WFI/WFE/sleep); CubeMX project setup; HAL vs LL driver selection; CI/CD for firmware; embedded code review; MPU configuration; watchdog strategies; safety-critical design (IEC 61508, SIL); peripheral protocol selection (UART/I2C/SPI/CAN); linker script memory placement; or C/C++ callback patterns. Also trigger on implicit cues like "my MCU keeps crashing", "writing firmware", "ISR safe", "embedded allocator", "no dynamic memory", "power consumption", "CubeMX regenerated my code", "which RTOS pattern should I use", "MPU fault", "watchdog keeps resetting", "which protocol should I use for my sensor", "ESP32 deep sleep", "PSRAM vs DRAM", "ESP32 heap keeps shrinking", "ESP.getFreeHeap()", "task stack overflow on ESP32", or "WiFi reconnect after deep sleep is slow".
Generate interactive presentation slides using React + Tailwind, and export to standalone single-file HTML. Triggers on keywords like "slides", "presentation", "PPT", "demo", "benchmark", or when user requests export. Uses agent-browser skill for browser verification before export (install with `npx skills add vercel-labs/agent-browser` if not available).
Create structured technology trade-off analysis documents with scored comparison matrices. Use this skill whenever the user wants to compare technologies, evaluate architectural options, analyze build-vs-buy decisions, assess migration strategies, or produce any decision document that compares multiple approaches across weighted dimensions. Triggers on: 'trade-off analysis', 'tradeoff', 'comparison matrix', 'evaluate options', 'which technology should we use', 'compare approaches', 'pros and cons of', 'build vs buy', 'migration analysis', 'consolidation analysis', 'technology selection'. Also use when the user has completed technical research and wants to structure findings into a decision document.
Use when investigating and documenting a production incident, outage, data corruption event, or post-mortem — guides evidence collection during the investigation AND produces a rich, reproducible Root Cause Analysis report. Trigger on phrases like "write an RCA", "post-mortem for X", "document this incident", "what went wrong with...", "the pipeline broke yesterday, help me investigate", or any time the user is debugging a recently-resolved incident and wants a writeup. Also use proactively when the user finishes resolving an incident in-session and the resolution context is fresh — offer to capture it as an RCA before details fade.
Integrated AI agent orchestration skill that combines plannotator, ralphmode, team or bmad execution, agent-browser verification, and agentation feedback loops, while maintaining a project-local `.jeo` ledger for planning, development, and QA. Use when the user wants an end-to-end multi-agent workflow with plan approval, implementation, UI review, cleanup, and durable task history. Triggers on: jeo, annotate, ui-review, multi-agent orchestration.
Route Unity and Unreal frame-time complaints into one bottleneck-first profiling brief. Use when the main job is interpreting profiler screenshots, `stat unit` / `stat gpu` output, benchmark-route complaints, or Steam Deck / target-device review packets; choosing the smallest useful next capture; naming one primary bottleneck family; and deciding whether to stay with quick packets, move to an engine-native profiler, or escalate further. Route generic app/service tuning to `performance-optimization`, build/editor/package failures to `game-build-log-triage`, broader game-production coordination to `bmad-gds`, and mixed demo/community feedback to `game-demo-feedback-triage`.
