How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

work-visualized

Claude Work Visualized: a live, animated map of the project showing where Claude reads, edits, creates and deletes files
workflow-map
1mimateinn/workflow-map
Live workflow map: one row above the prompt (what is running, what is next, segmented progress) that expands into a card graph of parallel steps, plus a full stage-by-stage view and a flowchart of parallel groups, with your mid-plan interjections clearly marked (whether they were recorded, what each one changed shown on the plan, the plan before it, a timeline), an honest time-left range, owners and timing per step, sub-agent sync and plan history.
work-session
1enhki/claude-mods
Kick off and wrap up working sessions with your start and end commands, and give each session a useful title
workflow-toolbox
1home-dev-lab/workflow-toolbox
Toolbox for Claude Code's Workflow tool — author deterministic multi-agent workflow scripts (workflow-composer, with the @workflow-toolbox compile-time pattern toolkit as its standard library), scaffold a build-clean workflow skeleton from a spec (toolkit-scaffold), diagnose a failed run from its journal and decide whether resumeFromRunId helps (workflow-debugger), re-verify the runtime surface after a Claude Code upgrade (upgrade-canary), run a bias-free multi-lens analysis of any subject when relevant (independent-analysis), ground checkable claims against real sources (deep-grounding), and adopt editable, versioned copies of the plugin's rules and agent definitions. Ships the independent-analysis workflow, finished-run audit notices, a tracker-agnostic actionability Stop gate with a Planka snapshot producer, the pilot agent suite (pilot / pilot-orchestrator / pilot-watchdog), pilot-wave composition, a conditional delegation ladder and delegation-chain reference. The planka-tracking skill onboards a project with lossless historical task migration. The retired work-journal CLI still reads, verifies and exports an existing journal; no hook records to it any more.

ClaudeWhip for Claude Desktop: the whip lane as a band above the prompt, hit toasts and a stats pane. Install alongside the ClaudeWhip plugin, which delivers the whips.
