You MUST use this before designing genuinely new features, components, or capabilities where the requirements are still open. Explores user intent, requirements and design before implementation. Not for bug fixes, refactors, or small well-specified changes — bias toward action applies there.

Upload local files (figures, images, any asset) to the user's public CDN at cdn.hails.info (Cloudflare R2) and get back public https URLs. Use when an image/file needs a public URL — e.g. embedding a figure inline in a PRIVATE-repo GitHub PR/issue description (private-repo raw/blob links do NOT render; a public…

End-user browser automation with cmux. Use when you need to open sites, interact with pages, wait for state changes, and extract data from cmux browser surfaces. Requires the macOS cmux app — skip on hosts without a reachable cmux socket.

Run end-user cmux diagnostics. Use when cmux hooks, notifications, session restore, settings, browser automation, socket access, CLI control, or agent resume behavior is not working, or when the user asks for a cmux health check, doctor report, or support-safe debug summary. Requires the macOS cmux app — skip on hosts…
Skill Claude CodeCodex
Fork the current agent session — Claude Code or pi — into a new cmux split pane (or tab): opens a split beside the caller, relaunches this session forked (claude --fork-session / pi --fork), titles it 'fork: ', and keeps that title. Use when the user asks to fork/duplicate/branch the current session into a new split…
Skill Claude CodeCodex
Guide and apply cmux keyboard shortcut customization. Use when the user asks to customize, rebind, unbind, reset, audit, or create shortcut templates for cmux, including tmux-style, Vim-style, terminal-first, browser-heavy, iTerm/Terminal-like, or agent-triage layouts. Requires the macOS cmux app — skip on hosts…
Skill Claude CodeCodex
Open markdown files in a formatted viewer panel with live reload. Use when you need to display plans, documentation, or notes alongside the terminal with rich rendering (headings, code blocks, tables, lists). Requires the macOS cmux app — skip on hosts without a reachable cmux socket.
Skill Claude CodeCodex
Manage the user's durable dev sessions — zellij sessions on remote hosts (bonbon, taffy) reached over mosh, plus the local host's (trifle) own detached zellij sessions, surfaced as cmux tabs via ssh::durable / zellij::resume. Load when the user wants to rebuild/resurrect lost cmux durable surfaces after a cmux restart…
Skill Claude CodeCodex
View and edit cmux settings in /.config/cmux/cmux.json. Use when the user wants to change cmux preferences (appearance, sidebar, notifications, automation, browser, shortcuts), set a value by JSON path, validate the file, open it in an editor, or look up which keys cmux recognizes. Triggers on '/cmux-settings'…
Skill Claude CodeCodex
Work inside the current cmux workspace and terminal. Use for cmux workspace, current workspace, caller surface, panes, surfaces, socket targeting, and non-interfering cmux automation. Requires the macOS cmux app — skip on hosts without a reachable cmux socket.
Skill Claude CodeCodex
End-user control of cmux topology and routing (windows, workspaces, panes/surfaces, focus, moves, reorder, identify, trigger flash). Use when automation needs deterministic placement and navigation in a multi-pane cmux layout. Requires the macOS cmux app — skip on hosts without a reachable cmux socket.
Skill Claude CodeCodex
Suggest a codename for a project. Fetches naming philosophy from hails.info/writing/codenames, studies the project context, then proposes names that are suggestive (not descriptive), memorable, and free of pop culture references.
