| description | Use when the user wants to convert a video or audio file's stereo audio to mono, or fix audio that only plays in one ear. |
This skill converts the stereo audio channel of a media file (typically video or audio) to mono. It optimizes the process by copying the video stream without re-encoding to preserve video quality, and handles silent channels by extracting the active channel rather than a simple downmix.
Use when a video or audio file's sound plays in only one ear/channel, or when a mono mix is requested.
ffmpeg -i <input> -filter_complex "[0:a]astats=metadata=1" -f null - to identify the peak and RMS volume of each channel.
Note: Do not use reset=1 in the filter, as it resets stats per frame.-af "pan=mono|c0=c0" (or FL)-af "pan=mono|c0=c1" (or FR)-ac 1ffmpeg -i <input> -c:v copy -af "<filter>" -c:a aac -b:a 256k <output>-c:v copy.-ac 1 downmix of a one-eared track averages it with silence, dropping the overall volume by 6 dB. Always analyze first and use the pan filter for single-channel isolation.Use when the user requests to update, upgrade, or install the latest release of Neovim.
Write a comprehensive, no-placeholder implementation plan as a series of bite-sized tasks, each with exact file paths, real code, TDD steps, and commit instructions. Saves as a GitHub Issue with a [PLAN] prefix. Use after preflight has established what to build.
Present a plan to the user for inline annotation via the ai-review UI. Use when you have a plan ready for human review before executing it. The user will annotate it in the browser; you then revise based on their comments.
Explain the core concepts, library design patterns, system architecture, or host environment internals involved in a plan or git diff. Spawns an isolated subagent to perform the education.
Capture an Architecture Decision Record (ADR) for a significant decision made in the current project. Store in the project's adrs/ folder. Use when the user asks to record a decision, log an ADR, or capture why something was built a certain way. PROACTIVELY suggest capturing an ADR whenever a non-obvious architectural choice is made — technology selection, structural trade-offs, rejected alternatives — especially after a discussion where context and reasoning were developed. A good prompt — "Want me to capture this as an ADR?"
Manage Jack's personal technical reference library at ~/git/references. Use for searching/reading existing references, or adding new ones. Invoke with /jack-references and optional keywords to search, or when the user wants to save a new reference guide. PROACTIVELY suggest saving a new reference whenever the conversation involves figuring out how a library, API, or tool works — especially after debugging, reading docs, or solving a non-obvious integration problem. A good prompt — "Want me to save this as a reference for next time?"
