AgentHub — Plugin Marketplace

Official Claude Code plugins for the Agent Monitor dashboard. The agenthub plugin is the dashboard — hooks, server and the agenthub CLI, no checkout required. (It ships a small read-only MCP server again — agenthub mcp, see MCP.md — but does not register it: run claude mcp add agenthub -- agenthub mcp to opt in. The same goes for the statusline, agenthub statusline install, see STATUSLINE.md.) On top of it, 10 focused plugins extend Claude Code with skills, agents, slash commands, hooks, and CLI tools for deep analytics, cost guardrails, productivity automation, developer tools, AI-powered insights, session forensics, workflow/fleet intelligence, reliability & SLOs, config & memory governance, and dashboard connectivity.

Every plugin is powered by the local Agent Monitor REST API at http://localhost:4820. They are read-only advisors unless a skill explicitly documents a mutating endpoint (and those preview + confirm before acting).

Quick Start

Add the marketplace

claude plugin marketplace add https://git.smartgift.io.vn/Smartgift-AI/AgentHub.git

Install the dashboard itself

claude plugin install agenthub@agenthub

That is the whole install: no clone, no npm run setup, no npm run install-hooks, no manual npm start. See The agenthub plugin below for what it does on first session start.

Or via the Smartgift skills marketplace

agenthub is also listed as a standalone entry in smartgift-claude-skills — its source still points at this repo's main branch, so the two entries install identically:

claude plugin marketplace add https://git.smartgift.io.vn/Smartgift-AI/smartgift-claude-skills.git
claude plugin install agenthub@sg

Pick whichever marketplace you already have added; installing agenthub from both at once is redundant but harmless (Claude Code treats it as one plugin per marketplace name, not per source).

Install a focused plugin

claude plugin install agenthub-analytics@agenthub
claude plugin install agenthub-cost-guard@agenthub
claude plugin install agenthub-productivity@agenthub
claude plugin install agenthub-devtools@agenthub
claude plugin install agenthub-insights@agenthub
claude plugin install agenthub-sessions@agenthub
claude plugin install agenthub-workflows@agenthub
claude plugin install agenthub-quality@agenthub
claude plugin install agenthub-config@agenthub
claude plugin install agenthub-dashboard@agenthub

Or install locally during development

# From the repo root, test a plugin locally
claude --plugin-dir plugins/agenthub-analytics

Prerequisites

• Claude Code installed and authenticated
• Node >= 22.5 when installing via the agenthub plugin. A plugin install has no native better-sqlite3, so the server stores data through node:sqlite, which landed in 22.5. The bootstrap refuses with one line on anything older instead of letting the server crash. (A checkout install still works on Node >= 20.)
• The Agent Monitor dashboard reachable at http://localhost:4820 — the agenthub plugin starts it for you; a checkout starts it with npm start (see SETUP.md)

Skills and commands are invoked as /agenthub-<plugin>:<name>. Agents are dispatched automatically by Claude Code (or named explicitly).

The agenthub plugin

The marketplace's root entry ("source": "./") is the entire repository, so server/, client/, scripts/ and bin/agenthub.js all land under ${CLAUDE_PLUGIN_ROOT} when Claude Code caches it. That is what makes a checkout unnecessary.

What it installs

Component	Where it comes from
The eight event hooks	inline hooks in .claude-plugin/plugin.json, each running scripts/hook-handler.js
The dashboard server	started detached by the bootstrap, from the plugin cache
The agenthub CLI	a launcher written to ~/.local/bin/agenthub
The dashboard UI (/run and every other client route)	built into the runtime dir by the bootstrap, so it works the moment claude starts
/agenthub-doctor, /agenthub-update, /agenthub-open	plugins/agenthub/commands/
The skills (update-project-docs, file-headers)	skills/ at the repo root — which IS the plugin root, so they are auto-discovered as plugin skills

Plugin skills are namespaced: they are invoked as /agenthub:<name>, with the bare /<name> working as an alias unless another skill or command claims that name. This is why skills/ sits at the repo root instead of .claude/skills/ — the latter only loads for a session whose cwd is inside this checkout, which is useless for a workspace working in a different repo.

That is the whole plugin: the hooks, the CLI, the dashboard, three commands and four skills. It ships no subagents and no pipeline template, and it neither depends on nor installs any other plugin (Superpowers included). The pipeline slash commands, the ship-feature / ship-feature-lane skills and the qc-local / senior-gate-reviewer / backend-reviewer / frontend-reviewer agents were removed; the stage/pipeline machinery they drove stays in the dashboard, dormant until you install a template (see docs/LANES.md § "Pipeline stages and the five node states").

Because the plugin ships the hooks itself, npm run install-hooks is not needed for plugin users — and must not be run alongside it. Events carry no id, so two handlers mean every token and cost figure is counted twice. claude plugin install writes the plugin's own hook entries into ~/.claude/settings.json too (${CLAUDE_PLUGIN_ROOT} resolved to the actual cache path) — confirmed against a real install — so those entries also contain hook-handler.js, same as a leftover checkout install. The bootstrap tells them apart by whether the command resolves under ~/.claude/plugins/cache/: only genuine checkout paths are removed (backing ~/.claude/settings.json up as settings.json.agenthub-bak first), never the plugin's own. /agenthub-doctor reports the state using the same check.

First session start

scripts/plugin-bootstrap.js runs from SessionStart. It returns within milliseconds — the real work happens in a detached worker, so a session never waits on an install:

1. Fast path — recorded state matches this plugin build and a server is live → exit. "Live" means a discovery entry whose pid answers AND whose startedAt is after this boot (60 s margin): an entry left over from before a reboot names a pid the OS may have handed to an unrelated process, and without systemd (macOS) nothing else clears it.
2. Superseded check — if Claude Code records a DIFFERENT build of this plugin as installed, this one logs a line and does nothing else (see A retired build never acts).
3. Node gate — refuse below 22.5 with one line (see Prerequisites).
4. Lock — atomic mkdir lock holding the PID; reclaimed when the owner is dead or the lock is older than 10 minutes, so two sessions cannot race the install or spawn two servers.
5. Install — npm install --omit=dev --ignore-scripts into the runtime dir, run as the npm bundled with the node running the bootstrap (npmCommand: its npm-cli.js beside process.execPath, no shell, that node's directory first on PATH; npm on PATH only when that node ships none) — the update chain runs with the dashboard server's environment, whose PATH need not reach npm.cmd on Windows. The UI build below and the doctor's npm row use the same npm (never into the plugin cache, which is garbage-collected and replaced on every update). --ignore-scripts keeps the root postinstall from pulling the whole Vite client toolchain.
6. Legacy hook cleanup — see above.
7. CLI — write the ~/.local/bin/agenthub launcher, never clobbering a agenthub the bootstrap did not write. It pins the node that ran the bootstrap and falls back to node on PATH when that binary is gone (a Homebrew Cellar or nvm path deleted by an upgrade).
8. UI build — client/ is copied into the runtime dir and built there (npm ci --include=dev --ignore-scripts, falling back to npm install with the same flags, then tsc -b and vite build run by the bootstrap's own node — the client's build script without npm run), landing in runtime/client-dist — the same directory the server serves from. Nothing in it looks node up on PATH: on Windows an install script or a .bin/*.cmd shim runs through cmd.exe, and the server's PATH may have no node (esbuild's postinstall failed there with "'node' is not recognized" and the update kept the old UI); esbuild, the only dependency with an install script, finds its binary without it. --include=dev is required, not tidy: the entire build toolchain (vite, typescript, @vitejs/plugin-react, tailwindcss, @types/*) is a devDependency, and npm reads an inherited NODE_ENV=production as --omit=dev. Every bootstrap descended from the running server carries that env — the self-update chain, and any SessionStart fired by a claude inside a tmux pane the server started — so without the flag the install drops vite and the build dies on missing types. Skipped when a bundle for the current version already exists; a failure here does not fail the bootstrap (the API still works, and /agenthub-open can retry) but does mean /run 404s until it's fixed — and when a bundle from the PREVIOUS version is still on disk the failure is quieter still: the dashboard keeps serving the old UI against the new API, visible only as the Settings page's UI build vX (rebuild client to match) line.
9. Server — when the user has turned Start AgentHub automatically on (Settings → System; OFF by default), install/refresh the agenthub.service unit on Linux — on macOS with a GUI login, the io.smartgift.agenthub LaunchAgent (see Auto-start on boot) — instead of a bare spawn, so the server is supervised and comes back after a reboot with no Claude Code session involved. Everywhere else (Windows, no systemd, a Mac reached only over SSH), spawn server/index.js detached, with NODE_PATH at the runtime node_modules and DASHBOARD_CLIENT_DIST at the runtime client-dist — scoped to this session, same as before this fell back to systemd.
10. Record state — runtime/state.json.
11. Prune retired cache copies — delete the plugin-cache directories earlier updates left behind (see Pruning the plugin cache). After step 10, so a prune that goes wrong cannot also cost the record of a bootstrap that went right.
12. Hand over to systemd — only when a unit of ours already owns the server (see Who may stop the server). Deliberately after step 10.

The first run takes a few minutes — most of it is the UI build, which is what makes client-only routes (http://localhost:4820/run, and every other page) work the moment claude starts, with no manual /agenthub-open step. Progress goes to ~/.claude/agenthub/runtime/bootstrap.log; the UI build's own output goes to client-build.log next to it; the server's own output goes to server.log.

A retired build never acts

claude plugin update unpacks the new version into a new cache directory and prints "Restart to apply changes". A Claude Code process that was already running does not: it keeps loading the OLD directory — skills, commands and hooks included — until it is restarted.

That used to be self-inflicting. Every session such a process opened ran the OLD plugin-bootstrap.js, which saw a state.json naming a different root, concluded the server had to be replaced, repointed agenthub.service at itself and restarted the dashboard onto the version the user had just upgraded away from. The dashboard then reported the old version and offered the update again — once per session, forever, while installed_plugins.json and the cache both said the new version was installed. A /agenthub-update from that session "succeeded" and changed nothing.

So the bootstrap now asks first (supersededBy): if Claude Code's ~/.claude/plugins/installed_plugins.json records a sibling directory as the installed build of this plugin, this build logs one line and returns superseded without touching dependencies, the unit, or the server. --force does not override it — the self-update chain and /agenthub-update run --force from the NEW directory, which is never superseded, so the only --force this can refuse is one that would deliberately downgrade.

It cannot hand over to the new build either: the process it would have to replace is the one loading it. Restarting Claude Code is the fix, and the log line says so.

Matching is by sibling directory rather than by the <plugin>@<marketplace> key, which holds without parsing a cache path or trusting a name. An entry pointing at a directory that no longer exists is ignored — a phantom must never wedge a bootstrap shut.

A build installed while the server kept running

The same record answers the opposite case. claude plugin update run from a terminal (or with only the Claude desktop app open) starts nothing: no SessionStart fires, so no bootstrap hands the server over, and the dashboard keeps running the old directory — across reboots too, since agenthub.service still names it and it still exists. agenthub open only opens the browser.

So getUpdatesStatus (server/lib/update-check.js) asks supersededBy for its own root: when a sibling build is the installed one, the status carries installed_not_running: {root, version} and update_available: true — with no network needed, so an unreachable forge can no longer hide it. The sidebar reads <version> installed, not running, and the update modal's Update now runs the usual chain; scripts/plugin-update-helper.js hands over to the recorded install first (supersededBy(oldRoot)), falling back to the newest sibling directory only when there is no record.

Separately, a plugin install whose release lookup failed (release_check not ok) now reads Could not check for updates in the connection details modal (opened from the status bar) instead of Up to date — a plugin install has no commit count to fall back on.

To hand over by hand without the dashboard:

node "$(python3 -c 'import json,os;d=json.load(open(os.path.expanduser("~/.claude/plugins/installed_plugins.json")));print([e["installPath"] for k,v in d["plugins"].items() if k.startswith("agenthub@") for e in v][0])')/scripts/plugin-bootstrap.js" --force

Pruning the plugin cache

Claude Code unpacks every update beside the last one and does not reliably remove the old. A machine that tracks releases closely accumulates a full copy of this repo — node_modules and all — per release; a dozen of them is gigabytes.

Step 11 of the bootstrap (pruneRetiredPluginRoots) deletes them. This is the only place anything in the plugin touches the cache, and the rule it appears to break ("never write into the plugin cache") is about the runtime living outside it, not about keeping retired copies forever.

Four independent readings of "still in use" are protected, and nothing matching any of them is ever deleted:

Protected	Why
This build	It is running.
Every installPath in installed_plugins.json, at any scope	Claude Code says it is installed.
The directory agenthub.service names (unitRoot, foreign unit included)	A service is executing from it. Not ours to rewrite is still not ours to delete.
Any directory named in the user's settings.json hooks	A Claude Code process that has not been restarted is still executing from there — this is the same directory the section above describes, seen from the other side. Deleting it would break that session's hooks mid-flight.

Plus the newest KEEP_RETIRED_ROOTS (1) of whatever is left, as a rollback cushion — one build deep, because a full copy of this repo is ~130 MB. Outside ~/.claude/plugins/cache/ the pruner does nothing at all — for a git checkout the parent directory holds the user's own work. Best effort throughout: a directory that will not delete is left alone, never an error.

Quit

Settings → System → Quit AgentHub or agenthub stop (issue #65, server/lib/quit.js, POST /api/settings/quit) closes every workspace terminal and stops the server, through the service manager when the unit runs it. It writes <data dir>/runtime/stopped first: while that file exists fastPathOk is true with no server and the worker starts none (--force, i.e. /agenthub-update, overrides it; a stale unit is still repaired, not started). Any server that starts clears it — agenthub start, which in a plugin install runs this bootstrap, or a boot/login through an enabled autostart unit — so autostart keeps working across a reboot.

Status-area icon

Like 9router's, AgentHub puts an icon beside the clock — GNOME's top bar, the macOS menu bar, the Windows notification area (server/lib/tray.js, scripts/tray.js). It is its own process, drawn by the systray2 package's helper binary (installed with the other runtime dependencies), so a server restart or a Quit never takes it away: after a Quit its Start AgentHub is the way back. A production server starts it once it is listening and checks every minute (a Linux server started at boot has no DISPLAY until someone logs in; three quick deaths in a row and that server stops trying). It is on by default; Hide this icon in its menu and Settings → System → Show AgentHub icon in the status area write <data dir>/runtime/tray-off, and only that switch removes it again. One icon per data dir: <data dir>/runtime/tray.json holds its pid and install root and is touched every 5 s as a heartbeat — a stale file is never trusted, so a pid reused after a reboot is never signalled. A server replaces an icon from another install root (the previous plugin build) once at start. Never in server mode, nor from a development server. The icon starts at login only when the dashboard does (start at login below); there is no separate autostart entry. Verified on Ubuntu GNOME (X11); on macOS systray2 ships only an x86_64 helper (Apple Silicon runs it through Rosetta 2, else no icon appears), and Windows is untested.

Auto-start on boot

Opt-in, and off by default: Settings → System → Start AgentHub automatically (GET/PUT /api/settings/autostart, server/lib/autostart.js). The switch IS the unit's enabled state — on writes a unit for the running server when none exists and enables it, off disables it; neither starts or stops the server. A bootstrap only installs or starts a unit that is enabled, never changes that state (writeUserService({ enable }) keeps it on a rewrite), and with it off the server is the detached spawn below. An install that already had the unit enabled before this switch existed keeps it on.

While it is on, every plugin bootstrap (not just the first) installs/refreshes a systemd --user service (~/.config/systemd/user/agenthub.service, managed via scripts/systemd-service.js — shared with the checkout path's agenthub service install, see the README). Its ExecStart/WorkingDirectory point at the current plugin cache path, so a plugin update that moves the cache directory rewrites and restarts the unit on the next session start, the same self-healing pattern the CLI launcher already uses. The bootstrap also tries loginctl enable-linger so the service starts on a cold boot before anyone logs in; when that needs elevated rights, it's skipped silently (check ~/.claude/agenthub/runtime/bootstrap.log, or run sudo loginctl enable-linger <user> once by hand). A pre-existing agenthub.service unit not written by this bootstrap is left untouched, and the server falls back to the old per-session detached spawn instead.

On macOS the same steps write a LaunchAgent instead (~/Library/LaunchAgents/io.smartgift.agenthub.plist, scripts/launchd-service.js; scripts/service-manager.js picks the one for the platform, and both export the same API). KeepAlive plays Restart=always, AbandonProcessGroup keeps the workspace panes' tmux server alive across a restart, output goes to ~/Library/Logs/agenthub.log, and the hand-over restart is launchctl bootout

• bootstrap (a kickstart would keep the old plist). If that bootstrap fails and no server is left running, the bootstrap starts one detached. A LaunchAgent needs the user's GUI login; without one (SSH only) launchctl print gui/<uid> fails and the server falls back to the detached spawn below.

On Windows, a Linux box without systemd, or a Mac with no GUI login, the server is a detached spawn started fresh on the next SessionStart after a reboot, same as always. That spawn inherits the Claude Code session's env, so server/index.js deletes the parent-session variables (CLAUDECODE, CLAUDE_CODE_SESSION_ID, CLAUDE_CODE_MESSAGING_*, CLAUDE_PLUGIN_ROOT, …) before anything else runs — otherwise tmux hands them to every workspace pane. It is a denylist: user configuration such as CLAUDE_CONFIG_DIR, CLAUDE_CODE_USE_BEDROCK and ANTHROPIC_* passes through. See INSTALL.md § macOS.

Who may stop the server

When a agenthub.service unit of ours exists, nothing else may stop the dashboard. The bootstrap that performs a self-update is spawned by the running server, so it lives inside that server's systemd cgroup. SIGTERM-ing the server from there breaks two ways at once:

• the server exits 0, and the unit's old Restart=on-failure read a clean exit as "meant to stop" — so systemd did not bring it back;
• KillMode=control-group (systemd's default) reaps every process in the cgroup when the main process exits, including the bootstrap itself — mid-run, before it could repoint the unit at the new plugin root or write runtime/state.json.

The result was a dashboard that went down on every self-update and stayed down until some later Claude Code session happened to bootstrap again, leaving a stale .bootstrap.lock and a state.json still naming the previous version.

So the order is fixed, and scripts/systemd-service.js splits its API to enforce it:

Situation	What the bootstrap does
A unit of ours owns the server (unitIsOurs)	Never stops it. writeUserService repoints the unit at the new plugin root without starting anything, the rest of the bootstrap runs, state is written, the lock is released — and only then restartUserService asks systemd to restart, with --no-block so being killed by its own request costs nothing.
No unit, or a foreign one	Unchanged: stop the old server, then installUserService (or a detached spawn where there is no systemd). Nothing here is inside a unit's cgroup, so the stop is safe.

The unit is written with Restart=always, not on-failure: a graceful SIGTERM from anything at all would otherwise leave the dashboard down for good. An explicit systemctl stop — which is what agenthub service uninstall and the Settings panel do — still stops it.

The unit also sets KillMode=process: a stop or an update's restart ends the server process alone. tmux forks its server from whichever process first asks for a session — the dashboard itself after a boot with autostart on — so it can live in the unit's cgroup, and control-group would kill it and every lane pane on each update. An update never closes a pane; only Quit does (it kills the agenthub-lane-* sessions itself). Existing units pick this up when the next update rewrites them; a checkout's unit on agenthub service install. The launchd twin is AbandonProcessGroup.

Belt and braces on Linux: the session that STARTS the tmux server (no server running yet) is created through systemd-run --user --scope (server/lib/tmux.js), so the server lives in a transient scope of its own — not in agenthub.service, and not in the terminal or IDE scope a dev server was started from. Stopping either, systemd-oomd reaping either, or an old unit still on control-group leaves the panes alone. With no user manager to ask (SSH without linger, no systemd) it falls back to a plain start. On macOS tmux daemonizes into its own session and the plist abandons its process group. On Windows (psmux) whether the server outlives the dashboard has not been verified yet.

agenthub service install (the checkout path) keeps using installUserService: it runs from your own shell, outside the unit's cgroup, so it may block and start in one step.

A unit pointing at a retired plugin root repairs itself on the next session. This is the residue an interrupted update leaves behind, and it is invisible while the dashboard is up: the server runs fine, every doctor row reads OK, and then a reboot starts a cache directory Claude Code deleted during the update — so the dashboard never comes back, for a reason nothing recorded. The fast path therefore checks it (unitIsStale, pure fs — it may not spawn a process on every SessionStart) and refuses to short-circuit, and the bootstrap rewrites the unit.

Repairing the unit is not restarting the server: when the running server is current and healthy, the corrected unit is simply left to take effect at the next start (pendingSystemdRestart = systemdOwned && needsServer). Restarting a working dashboard to fix a file that only matters at boot would be churn the user feels for nothing. For the same reason the detached-spawn fallback is guarded by needsServer — entering that branch for a stale unit alone would start a second server onto a port the live one already holds.

systemdOwned requires the unit to be active, not merely present: an installed-but-stopped unit owns nothing, and treating it as the owner would skip the stop and then ask systemd to bind an occupied port — a crash loop, courtesy of Restart=always.

Commands

Command	Does
/agenthub-doctor	Node version, bootstrap state, runtime deps, server liveness, duplicate hooks, CLI launcher + PATH, systemd (WARN when the unit names a retired plugin root — the dashboard will not survive a reboot — or when it is installed but stopped; no unit at all is fine), tmux (WARN when absent — only the run console, agenthub workspace shell and session reloads need it), UI bundle. On any FAIL/WARN it asks whether to fix them, then lists the exact steps (one plugin-bootstrap.js --force from the installed build for deps/server/hooks/CLI launcher/stale unit, Node ≥ 22.5 through the user's version manager, the tmux package, the PATH line, …) and runs them only after a second yes; disk, a foreign unit, tmux built from source and an older running tmux server are reported, never touched. plugin-doctor.js itself stays read-only
/agenthub-update	Pull the latest agenthub release via claude plugin marketplace update + claude plugin update agenthub@<marketplace> -y, then reinstall dependencies and restart the server with plugin-bootstrap.js --force run from the build that is INSTALLED now (supersededBy() of this session's root, else that root — the old root's bootstrap would refuse as superseded), and run the doctor. The dashboard is on the new version at once; only this session's own commands and skills wait for /reload-plugins or a new session.
/agenthub-open	Rebuild the UI bundle and print the dashboard URL. Re-runs the bootstrap first when the server is down or still executing a plugin root that a mid-session /plugin update retired, so a fresh bundle never talks to an older server's routes. plugin-open.js exits 1 when the build fails or that bootstrap does not answer ok, and the command then runs the /agenthub-doctor flow and retries the build once after the approved fixes

Where things live

Thing	Location	Survives a plugin update
SQLite DB, transcripts	~/.claude/agenthub/	yes
node_modules, client-dist, logs, lock, state.json	~/.claude/agenthub/runtime/	yes (re-verified on every session start)
Source, hooks	the plugin cache version directory	no — re-bootstrapped

The bootstrap deliberately does not set DASHBOARD_DATA_DIR: leaving the default keeps a plugin-run server and a developer's npm run dev server on one data directory, where ingestGroupKey already deduplicates hook ingest to a single port.

Settings the dashboard saves (CLAUDE_HOME, CODEX_HOME, and the data dir that a CLAUDE_HOME change pins) go to ~/.config/agenthub/settings.env ($XDG_CONFIG_HOME/agenthub/settings.env, or AGENTHUB_SETTINGS_FILE), never to a .env inside the plugin cache, which every update replaces. The server reads it at startup. Precedence is real environment, then the checkout's own .env, then that file — a dev checkout whose .env names its own DASHBOARD_DATA_DIR must not be pointed at the live database by a pin saved from the plugin dashboard. A variable the real environment or that .env sets (a systemd unit's Environment=, say) wins at every start, and the settings page warns about it.

Uninstalling

claude plugin uninstall agenthub@agenthub only removes the plugin from the enabled list — verified against a real install/uninstall, not assumed. It does not:

• stop the running server (it keeps serving from the now-uninstalled cache dir)
• disable or remove the agenthub.service systemd --user unit (Linux) — it will keep restarting the old server on every reboot, since systemctl knows nothing about claude plugin uninstall
• remove the cached source under ~/.claude/plugins/cache/.../agenthub/<version>/
• remove the hook entries claude plugin install wrote into ~/.claude/settings.json (still pointing at that cache dir — they keep firing, and keep working, until the cache directory is eventually GC'd by Claude Code, at which point they silently start failing)
• remove ~/.local/bin/agenthub or ~/.claude/agenthub/runtime/

For a clean machine, do all of this yourself:

# 1. Stop the server. On Linux, disable the systemd unit FIRST — the unit is
#    Restart=always, so a bare `kill` is always undone by systemd.
systemctl --user disable --now agenthub.service 2>/dev/null
rm -f ~/.config/systemd/user/agenthub.service && systemctl --user daemon-reload 2>/dev/null
# Fallback for a detached (non-systemd) server, or if the unit above was absent:
kill "$(node -e 'console.log(JSON.parse(require("fs").readFileSync(require("os").homedir()+"/.claude/.agenthub.json","utf8")).pid)')" 2>/dev/null

# 2. Runtime state and the CLI launcher
rm -rf ~/.claude/agenthub/runtime    # deps, UI bundle, logs, state
rm -f ~/.local/bin/agenthub

# 3. The hook entries claude plugin install wrote (settings.json is not
#    ours to fully own — back it up first and only drop entries mentioning
#    hook-handler.js)
node -e '
const fs = require("fs");
const p = require("os").homedir() + "/.claude/settings.json";
const d = JSON.parse(fs.readFileSync(p, "utf8"));
fs.copyFileSync(p, p + ".agenthub-bak2");
for (const [type, entries] of Object.entries(d.hooks || {})) {
  const kept = entries.filter((e) => !JSON.stringify(e).includes("hook-handler.js"));
  if (kept.length) d.hooks[type] = kept; else delete d.hooks[type];
}
fs.writeFileSync(p, JSON.stringify(d, null, 2) + "\n");
'

~/.claude/agenthub/ still holds the SQLite database after all of the above — delete that directory too only if you want the recorded history gone.

Data Model Reference

These plugins query the Agent Monitor API at http://localhost:4820. Key data shapes:

Token Tracking

• 4 token types: input_tokens, output_tokens, cache_read_input_tokens, cache_creation_input_tokens
• 4 baselines: baseline_input, baseline_output, baseline_cache_read, baseline_cache_write (preserve pre-compaction tokens)
• Effective total = current + baseline (the /api/analytics totals are pre-summed)

Cost Calculation

• Formula: (tokens / 1,000,000) × rate_per_mtok for each token type
• Model matching: longest model_pattern wins (e.g., claude-sonnet-4-5% beats claude-sonnet-4%)
• Pre-seeded rates for Opus, Sonnet, Haiku families

Session Metadata (JSON)

• thinking_blocks: count of extended thinking blocks
• turn_count: number of conversation turns
• total_turn_duration_ms: cumulative turn processing time
• usage_extras: { service_tiers[], speeds[], inference_geos[] }

Event Types

PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, Notification, Compaction, APIError, TurnDuration, ToolError, Interrupted

Workflow Intelligence API (/api/workflows/{sessionId})

11 datasets: stats, orchestration (DAG), toolFlow (transitions), effectiveness (subagent success), patterns (recurring sequences), modelDelegation, errorPropagation (by depth), concurrency (lanes), complexity (score), compaction (impact), cooccurrence (agent pairs)

Alert Rules (/api/alerts/rules)

Rule types: budget ({ period: day|week|month, limit_usd, thresholds: [80, 100], tool?, lane?, tz_offset? } — a spend limit in dollars, each threshold firing once per period; GET /api/budgets/status reports the current period), cost_threshold ({ usd } per session), token_threshold ({ total_tokens }), event_pattern, inactivity, status_duration. POST /api/alerts/rules/preview dry-runs any of them over recorded history.

Config Explorer (/api/cc-config/*)

Read every Claude Code surface (skills, agents, commands, output-styles, plugins, marketplaces, mcp, hooks, settings, keybindings, statusline, memory). A plugin card's contribution chips are clickable: each one expands to name the skills / subagents / commands / output styles that plugin ships (from contributes.items), so the plugin's contents are readable without opening its install directory. memory includes the per-project file-based store with scope: "auto-memory" (carrying project, name, isIndex, frontmatter); those files plus CLAUDE.md are mutable via PUT/DELETE /api/cc-config/file with always-on timestamped backups. The page also manages plugins and marketplaces: paste a GitHub owner/repo, URL or local path to register a marketplace, then install / enable / disable / update / uninstall its plugins — each button runs the corresponding claude plugin … command on the dashboard host (argv array, never a shell string). Hooks and settings.json keys are editable per layer (user / project / project-local) through PATCH /api/cc-config/settings, a per-key merge that leaves every untouched key — including redacted secrets — exactly as it was.

Plugin structure

my-plugin/
├── .claude-plugin/
│   └── plugin.json          # Required: name (== dir name), description, version
├── skills/
│   └── my-skill/
│       └── SKILL.md         # Skill (description-only frontmatter; uses $ARGUMENTS)
├── agents/

├── commands/

└── settings.json            # Plugin settings

Structure is validated by server/__tests__/plugins-marketplace.test.js, which enforces the marketplace↔directory bijection, plugin.json shape, name/dir agreement, and required frontmatter on every agent / skill / command.

Two of those shape rules exist because getting them wrong makes a plugin listed but uninstallable, with no other symptom — the marketplace loads fine and only claude plugin install fails:

• A subdirectory entry declares "source": "./plugins/<name>", never "path". path is not a source key the CLI accepts (This plugin's marketplace entry is invalid: source: Invalid input).
• A plugin.json's repository is a string, not npm's { "type", "url" } object (Validation errors: repository: Invalid input).

server/__tests__/repo-links.test.js guards the link side: no GitHub owner/repo marketplace shorthand (it resolves to github.com only — this repo is on Gitea, so the shorthand cannot work and no GH_HOST-style env var redirects it), no raw.githubusercontent.com / *.github.io / GitHub /blob/<branch>/ URLs, no retired repository name, and no stale committed openapi.yaml.
