Claude Code Command Center

The ultimate monorepo for working with Claude Code — apps you run, utility tools, and shared libraries, all centered on Claude Code.

Each member keeps its own README.md and CLAUDE.md (plus a CHANGELOG.md once it is released independently). This front page is the catalog; click into a folder for full docs. Releases are tagged per component — see the release guide.

Catalog

apps/ — full applications you run

App	What it does
cross-repo-file-diff	Survey many local repos from one board; diff and copy files across any two of them. Serverless, no build (Chromium only).
multi-repo-plan-runner	A command center over the Claude Code repos you work across: surface every plan and its lifecycle status, and run plans without leaving the tool.
multi-repo-workspace	Turn-based workspace over your Claude Code repos (internal name roundtable): a board of repos with live git/plan state, in-app Claude Code planning sessions, rounds of orders executed headlessly with live streams and per-run cost, and a review phase with diffs, commits, and carried follow-ups. Successor to multi-repo-plan-runner; both share the same lifecycle sidecar format.
per-project-plugin-toggler	Enable/disable Claude Code plugins per project from a browser UI or inside VSCode; browse and install from known marketplaces.
usage-dashboard	Interactive local web dashboard for token usage, cost, and rate limits: range/project scoping, plan ROI, trend deltas, activity/model/tool profiles, drill-down with shareable URLs, session economics, a live rate-limit trajectory with cap ETA, and Markdown/CSV export. Reads Claude Code transcripts; live rate limits read an optional statusline JSONL export, which no tool in this repo writes yet.
usage-insights	Local dashboard that helps you decide what to change: this week's and month's token and cost forecast, where spend goes by project, model, and session, and which skills, subagents, and tools are never used, fading, or followed by trouble. Keeps its own transcript store, so history outlives Claude Code's cleanup. Replaces usage-dashboard.
claude-component-browser	Local web app to search and read every Claude Code component — skill, agent, and hook — on your machine, from installed plugins and from loose (non-plugin) .claude skills/agents, grouped by source.

tools/ — single-purpose utilities & scripts

Tool	What it does
statusline-hook	Claude Code statusline (bash + jq, or PowerShell) with model, context, runtime and cost on one row and aligned 5-hour / 7-day rate-limit gauges below.
session-name-date-prefixer	Prefix Claude Code session names with the date.
file-sync	Keep a named file in sync across two folders (newer wins): CLAUDE.md (raw copy) and settings.json (JSON merge, excluded keys preserved), via one generic engine.
scheduled-session-digests	Install once and it runs in the background: every night, headless Claude Code turns each of your new sessions into a lessons-learned file, and every week merges the new lessons into one master file, in a local git repo you own. Also keeps a cleaned copy of each session's transcript.
agents-workspace-sync	Daily unattended commit and push of a configured list of .agents_workspace repos; each must be a standalone git repo, and each is pushed on the branch it is already on.
marketplace-updater	On a schedule, refreshes the Claude Code marketplaces you list and updates their plugins in the repos you list. Marketplaces, repos, and interval are all config.
usage-report	CLI summary of token usage and estimated cost across sessions — the terminal counterpart to usage-dashboard.

statusline-hook, session-name-date-prefixer, claude-md-sync, settings-sync, and the usage-dashboard app were originally one claude-automation suite; see docs/automation-suite.md for the combined overview.

libs/ — shared libraries

Library	What it does
claude-usage	Dependency-free library that reads Claude Code's ~/.claude/projects/**/*.jsonl transcripts into per-session token/cost data, plus the model pricing table.
claude-plugins	Dependency-free library that reads Claude Code's installed plugins and their skills/agents/hooks from local config into typed records.

A library earns a place here only with a cohesive domain and ≥2 real consumers — not as a utilities junk drawer. claude-usage qualifies (the transcript layout, consumed by the usage-dashboard and usage-insights apps and the usage-report CLI); so does claude-plugins (the installed-plugin layout, consumed by the claude-component-browser, per-project-plugin-toggler, and usage-insights apps).

Installing the tools

The installable tools/ members (statusline-hook, session-name-date-prefixer, file-sync, scheduled-session-digests) can be installed, uninstalled, and tracked from one place via setup/command-center.ps1:

./setup/command-center.ps1 status                 # what's installed on this machine
./setup/command-center.ps1 install -Member statusline-hook
./setup/command-center.ps1 install -All           # reads ~/.claude-command-center/config.json
./setup/command-center.ps1 uninstall -All

It delegates to each tool's own setup script and records state in a manifest under ~/.claude-command-center/. See setup/README.md. It also manages the two apps that register a scheduled task, usage-dashboard and usage-insights. Other apps and usage-report are run on demand, not installed, so they are not managed here.

Environment variables

Every environment variable this repo defines is prefixed C4_ (the repo's own namespace) so it never collides with Claude Code's or the OS's variables:

Variable	Used by	Purpose
C4_CLAUDE_DIR	usage-report, usage-dashboard, usage-insights, scheduled-session-digests, setup/	Override the Claude config dir (default ~/.claude); pathsep-separated, first entry wins. scheduled-session-digests reads every entry, at install time.
C4_CLAUDE_META_DIR	scheduled-session-digests, agents-workspace-sync, setup/	Location of the claude-meta directory (default ~/claude-meta). scheduled-session-digests reads it only as the default for -MetaDir and never sets it.
C4_STATUSLINE_NOW	statusline-hook	Test-only: pins "now" (epoch seconds) for the golden fixtures.
C4_STATUSLINE_LIVE_TIMEOUT	usage-dashboard	Seconds a session may be idle before dropping out of the live view (default 1800).
C4_PLAN_PRICE_USD	usage-dashboard	Monthly Claude subscription price; lights up the dashboard's Plan Value (ROI) card when set.
C4_USAGE_INSIGHTS_HOME	usage-insights	Store dir holding usage.db, reference.json, and layout.json (default ~/.usage-insights).
C4_USAGE_INSIGHTS_API_KEY	usage-insights	Anthropic API key for the chat; unset turns it off. Not ANTHROPIC_API_KEY, which Claude Code reads too. Each message spends API credit.
C4_USAGE_INSIGHTS_MODEL	usage-insights	Model the chat runs on (default claude-sonnet-5-5).
C4_STUB_LIST, C4_STUB_LIST_FAIL, C4_STUB_LOG	marketplace-updater	Test-only: the stub claude CLI's plugin list file, a switch that makes the list fail, and its call log.
C4_ROUNDTABLE_REGISTRY	multi-repo-workspace	Registry file path (overridden by --registry, ahead of ./.roundtable.json).
C4_ROUNDTABLE_HOME	multi-repo-workspace	App state dir — rounds, session transcripts, run output (default ~/.roundtable).

OS-provided variables (USERPROFILE, LOCALAPPDATA, PATH, …) are not ours and keep their names.

Decisions

Agent decisions are logged in .agents_workspace/DECISION_LOG.md, with historical per-member logs consolidated in .agents_workspace/archive/decision-log.md. That folder is not tracked here — it is its own git repo on the claude-code-command-center orphan branch of a private agents-workspace remote, git-ignored by this repo and pushed daily by agents-workspace-sync.
