Stage and commit changes with a Conventional Commits message. Matches the repo's existing style, writes a structured subject and body, and commits without push/force/amend. Use whenever the user wants to commit, ship, save progress, or close out a task — including "commit this", "make a commit", "commit the changes", or "/skill:commit".
Render a plan, review, design, or any structured topic as a single skimmable HTML file in the current directory, built for visual review (diagrams, charts, stats, side-by-side, tables, callouts) instead of prose. Use whenever the user says "make an html for this", "show me this as a page", "render this as html", "visualize this", "build a review page", "build a dashboard", "/skill:to-html", or when the topic has flows, before/after, trade-offs, file-by-file changes, metrics, quantitative data, or risks that would be faster to grasp visually than to read in chat. Bias toward triggering whenever a wall of text in chat would be harder to skim than a page.
Ground facts about a third-party dependency by reading its actual source at the installed version, instead of recalling it from memory. Clones the upstream repo into .agent-sources/ (git-excluded), checks out the tag matching the installed version, then delegates read-only subagents to trace exact behavior. Use proactively while building — before calling an unfamiliar dependency API, relying on a signature/default/return type, or explaining how a library works — and whenever debugging behavior that originates inside a dependency. Prefer this over training knowledge, which drifts from the version a project actually has installed and invents APIs that don't exist.
