Explorar skills

Abductive reasoning about causes. Takes a phenomenon, separates observations from interpretations, then spawns diagnosticians applying different reasoning lenses (technical, human-factors, process, incentive-structure, environmental, temporal, measurement-artifact, statistical) in isolation. Orchestrator evaluates candidate causes for fit-against-evidence, calibrates confidence honestly, and repor

Video editing operations using FFmpeg: trimming, cutting, splitting, concatenation, speed changes, cropping, scaling, rotation, overlays, picture-in-picture, green screen removal, video stabilization, transitions, fades, privacy blur, LUT color grading, and motion tracking text. Use when user says "trim", "cut", "split", "merge", "concat", "speed up", "slow down", "crop", "scale", "rotate", "overl

Perform thorough code reviews — bugs, security issues, performance bottlenecks, style violations, and architectural concerns.

Exploratory workflow for understanding problem spaces and drafting feature proposals, refactorings, or complex bug-fixes. Creates detailed tickets in your issue tracker without doing implementation work.

Diagnose and fix bugs systematically — error analysis, stack trace interpretation, root cause identification, and fix suggestions.

Smart code scanner that detects Spring Boot patterns and routes to appropriate skills. Use when editing Java or Kotlin files in Spring Boot projects, working with pom.xml/build.gradle containing spring-boot-starter, or when context suggests Spring Boot development. Detects annotations (@RestController, @Entity, @EnableWebSecurity, @SpringBootTest) to determine relevant skills and provides contextu

Design full online courses — learning objectives, module outlines, lesson scripts, quizzes, and assessment rubrics.

Research a question, check existing knowledge first, draft a knowledge doc from the answer, and save directly to the appropriate category. Use when user says "/aria-cowork:ask", "ask about", "research and save", "I want to learn about", "what is the pattern for". Skips backlogs — the user reviews the answer in real-time before saving. (Cowork variant — namespaced-only.)

Speech-to-text transcription and animated subtitle generation using Whisper and FFmpeg. Creates word-by-word animated captions (karaoke-style), SRT/ASS/VTT subtitles, burns subtitles into video, extracts existing subtitles, converts between formats, and styles captions with custom fonts, colors, and animations. Use when user says "caption", "subtitle", "transcribe", "whisper", "SRT", "ASS", "VTT",

Write and optimize complex SQL queries — JOINs, CTEs, window functions, query plans, and dialect-specific syntax.

Data-driven performance optimization through profiling and infrastructure tuning

Retrospective learning from a completed experience. Takes a project, incident, decision that played out, or time period; gathers ground truth (observations) separately from recollections; spawns reflectors applying different lenses (what-worked-vs-got-lucky, what-didn't, what-surprised, system-rewards-vs-intent, decisions-that-aged, what-to-tell-past-self, patterns-that-recur) in isolation; synthe
