Project App

Day-to-day, you shouldn't need this skill at all — once install-app (PHASE 5) has run once (automatically, via /core-bootstrap or the first time this skill's default path runs), the board lives behind a single Dock/Launchpad (macOS) or taskbar/Start (Windows) icon: click it, the board opens, minimize/restore works natively. This skill is the install/control layer underneath that icon, plus a fallback opener for before it exists yet:

• stop — pause the background service. Closing the PWA window doesn't do this (the LaunchAgent/Scheduled Task keeps serve-backlog.js running on purpose) — this is the only interface to actually stop it.
• Root-mismatch self-heal (default path, PHASE 1) — if projects_root changes, the background service keeps serving the old one until something detects and restarts it; the LaunchAgent/Task alone can't do that.
• install-app — (re)run the full background-service + PWA setup. Needed after a projects-root change, an icon/script update, or on a machine where the auto-install (PHASE 0 / core-bootstrap PHASE 2.5) hasn't run yet or failed (e.g. Node wasn't installed at the time).
• Default path as fallback opener — starts the server if needed and opens it in a window. This still matters for the very first open on a machine: before the PWA is installed there's no icon to click yet, and not every setup path (e.g. /project-add restoring an existing project without going through core-setup's greenfield flow) surfaces a link on its own.

Serves all project backlogs and dashboards at http://localhost:9876. The server also serves a PWA manifest + service worker (/manifest.webmanifest, /sw.js) — the whole origin (index, dashboards, backlogs, reviews) is installable from the browser's "Install app" prompt for that permanent icon.

The background process itself installs automatically — serve-backlog.js starts at login (BACKLOG_IDLE_SHUTDOWN_MS=0 so its idle auto-shutdown never fights the background-restart mechanism), silently, via /core-bootstrap PHASE 2.5 or this skill's own PHASE 0 the first time it's found missing (shared/APP-INSTALL-CHECK.md). On macOS this is a LaunchAgent (KeepAlive, restarts on crash too); on Windows a Scheduled Task (AtLogOn — restarts at next login, not mid-session, since a detached start has no crash-restart hook). An earlier on-demand-launcher model needed a second icon for exactly that reason on macOS — a PWA can't start itself — install-app replaces it and removes the old launcher if found.

Multi-device — same backlog/dashboard content, not real-time: this skill only starts/stops the local server; it doesn't sync .project/ data by itself. Use /project-sync push (Mac) → clone the repo + /project-add (or /project-sync pull on an existing clone) on the new machine to bring the backlog/dashboard content over via the claude/state orphan branch — a deliberate push/pull step, not continuous sync. Requires a git remote both machines can reach; only text travels (screenshots/wireframes and credentials don't). See shared/STATE-SYNC.md for the full mechanics.

Trigger

/project-app — opens the app window (starts the server first if needed; auto-installs the background service on first run, see PHASE 0). Optional argument: stop, or install-app (macOS + Windows — force a full background-server + PWA setup/update, see PHASE 5).

Platform

Detect platform:

• Windows: $PSVersionTable bestaat → PowerShell
• macOS: bash

Projects root (first match wins):

1. Env var CLAUDE_PROJECTS_ROOT
2. <config_repo>/.claude/paths.local.yaml → veld projects_root (geschreven door /core-bootstrap)
3. Windows fallback: C:\Projects
4. macOS fallback: $HOME/projects

config_repo = parent van de gederefereerde symlink/junction ~/.claude/skills.

Server-script pad: ~/.claude/skills/shared/references/serve-backlog.js

Process

Execution rule: shell state (variables like $root/$SERVER_RUNNING, function definitions like resolve_projects_root) does not persist across separate Bash tool calls — only the working directory does. Run each phase's code blocks (resolve → validate → branch → start/stop) as one Bash invocation per phase, not split across multiple calls. Splitting them silently drops $root (empty-string checks then pass/fail unpredictably) and is the most common cause of this skill misbehaving — it is not a bug in the extraction commands themselves.

PHASE 0: Ensure background service, then check current status

Sub-step A — auto-install check (default path only). Skip this sub-step entirely when the argument is stop (don't install just to immediately stop) or install-app (PHASE 5 already runs the full install unconditionally — this would be redundant). Otherwise:

Todo: Read .claude/skills/shared/APP-INSTALL-CHECK.md and follow it.

Store the outcome as AUTO_INSTALLED — true if it returned INSTALLED_NOW, false for ALREADY_INSTALLED or SKIPPED: <reason> (keep the reason for the PHASE 2 report if skipped). This is purely additive: whether it installs, skips, or fails, PHASE 1 below still runs its own existing "start the server if not running" logic regardless — nothing here is a hard dependency.

Sub-step B — status check.

Windows (PowerShell):

try { Invoke-WebRequest -Uri http://localhost:9876/ -UseBasicParsing -TimeoutSec 2 | Out-Null; "RUNNING" } catch { "STOPPED" }

macOS (bash):

curl -s http://localhost:9876/ > /dev/null 2>&1 && echo RUNNING || echo STOPPED

Store result as SERVER_RUNNING.

PHASE 1: Execute action

Resolve $root first (altijd, ook als server al draait). If the resolved root does not exist as a directory, prompt for a new path and persist it to paths.local.yaml before continuing:

Windows:

function Resolve-ProjectsRoot {
  if ($env:CLAUDE_PROJECTS_ROOT) { return $env:CLAUDE_PROJECTS_ROOT }
  $skillsLink = Get-Item "$env:USERPROFILE\.claude\skills" -ErrorAction SilentlyContinue
  if ($skillsLink -and $skillsLink.Target) {
    $repo = Split-Path -Parent $skillsLink.Target
    $yaml = Join-Path $repo ".claude\paths.local.yaml"
    if (Test-Path $yaml) {
      $line = Select-String -Path $yaml -Pattern '^\s*projects_root:\s*"?([^"\r\n]+)"?' | Select-Object -First 1
      if ($line) { return $line.Matches[0].Groups[1].Value.Trim().TrimEnd('"') }
    }
  }
  return "C:\Projects"
}
$root = Resolve-ProjectsRoot

# Validate the resolved root exists. A stale/incorrect projects_root leaves the
# board empty — offer to fix it and persist to paths.local.yaml (the source of truth).
if (-not (Test-Path $root -PathType Container)) {
  # AskUserQuestion (open text input): projects_root "$root" does not exist —
  # ask for a new absolute path that must exist as a directory. Store in $newRoot.
  # (If $env:CLAUDE_PROJECTS_ROOT is set it keeps overriding on the next run — note that.)
  $skillsLink = Get-Item "$env:USERPROFILE\.claude\skills" -ErrorAction SilentlyContinue
  if ($skillsLink -and $skillsLink.Target) {
    $yaml = Join-Path (Split-Path -Parent $skillsLink.Target) ".claude\paths.local.yaml"
    if (Test-Path $yaml) {
      (Get-Content $yaml -Raw) -replace '(?m)^(\s*projects_root:).*', "`$1 `"$newRoot`"" | Set-Content $yaml
    }
  }
  $root = $newRoot
}

# If a server is already running, verify it serves the resolved root.
$rootMatches = $true
if ($SERVER_RUNNING -eq "RUNNING") {
  try {
    $served = (Invoke-WebRequest -Uri http://localhost:9876/__root -UseBasicParsing -TimeoutSec 2 | ConvertFrom-Json).root
    $servedNorm = try { (Resolve-Path $served -ErrorAction Stop).Path } catch { $served }
    $rootNorm = try { (Resolve-Path $root -ErrorAction Stop).Path } catch { $root }
    if ($served -and -not ($servedNorm -ieq $rootNorm)) { $rootMatches = $false }
  } catch {}
}

macOS:

resolve_projects_root() {
  if [ -n "$CLAUDE_PROJECTS_ROOT" ]; then printf '%s' "$CLAUDE_PROJECTS_ROOT"; return; fi
  local repo
  repo="$(cd "$HOME/.claude/skills" 2>/dev/null && pwd -P | sed 's|/[^/]*$||')"
  local yaml="$repo/.claude/paths.local.yaml"
  if [ -f "$yaml" ]; then
    local v
    v=$(awk -F'"' '/^[[:space:]]*projects_root:/ {print $2; exit}' "$yaml")
    if [ -n "$v" ]; then
      v="${v/#\~/$HOME}"; v="${v/#\$HOME/$HOME}"
      printf '%s' "$v"; return
    fi
  fi
  printf '%s' "$HOME/projects"
}
root="$(resolve_projects_root)"

# Validate the resolved root exists. A stale/incorrect projects_root leaves the
# board empty — offer to fix it and persist to paths.local.yaml (the source of truth).
if [ ! -d "$root" ]; then
  # AskUserQuestion (open text input): projects_root "$root" does not exist —
  # ask for a new absolute path that must exist as a directory. Store in NEW_ROOT.
  # (If $CLAUDE_PROJECTS_ROOT is set it keeps overriding on the next run — note that.)
  repo="$(cd "$HOME/.claude/skills" 2>/dev/null && pwd -P | sed 's|/[^/]*$||')"
  yaml="$repo/.claude/paths.local.yaml"
  if [ -f "$yaml" ]; then
    sed -i '' 's|^\([[:space:]]*projects_root:\).*|\1 "'"$NEW_ROOT"'"|' "$yaml"
  fi
  root="$NEW_ROOT"
fi

# If a server is already running, verify it serves the resolved root.
ROOT_MATCHES=true
if [ "$SERVER_RUNNING" = RUNNING ]; then
  served="$(curl -s http://localhost:9876/__root | sed -n 's/.*"root":"\([^"]*\)".*/\1/p')"
  canon() { (cd "$1" 2>/dev/null && pwd -P) || printf '%s' "$1"; }
  if [ -n "$served" ] && [ "$(canon "$served")" != "$(canon "$root")" ]; then
    ROOT_MATCHES=false
  fi
fi

If argument stop:

Windows:

Get-NetTCPConnection -LocalPort 9876 -ErrorAction SilentlyContinue | ForEach-Object { Stop-Process -Id $_.OwningProcess -Force }

If install-app (PHASE 5) was run, the Scheduled Task only triggers AtLogOn — unlike macOS's KeepAlive, there's no mid-session auto-restart to fight, so this kill just works and the server stays down until the next login. To stop it permanently (not just for this session), disable the task: Disable-ScheduledTask -TaskName "ClaudeConfigProjectBoard".

macOS:

launchctl bootout "gui/$(id -u)/com.claude-config.project-board" 2>/dev/null
kill $(lsof -ti:9876) 2>/dev/null

If install-app (PHASE 5) was run, a LaunchAgent restarts the server automatically (KeepAlive) — plain kill alone would just bounce right back. launchctl bootout unloads the agent first so the kill actually sticks; it's a no-op (silently fails, ignored) when no agent is installed, so this line is safe to always run.

Confirm result. If no server was running → report that. Stop here — do not continue to PHASE 2-4.

No argument (default): pick the branch below to ensure the server is running, then continue through PHASE 2, 3, and 4 in order — PHASE 4 (open the app window) always runs, it is not a separate mode.

• SERVER_RUNNING = true && root matches (ROOT_MATCHES/$rootMatches true): jump directly to PHASE 2 — fast path, don't restart (keeps open boards/SSE alive). COLD_START=false.
• SERVER_RUNNING = true && root mismatches: a stale server is bound to a different projects root. Kill it (use the stop kill command above), then start a fresh server with $root. Mention in the report that the server was restarted because the projects root changed. COLD_START=true.
• SERVER_RUNNING = false: start the server. COLD_START=true.

Start the server (mismatch-restart and cold-start both use this):

Windows:

Start-Process -WindowStyle Hidden -FilePath node -ArgumentList "--watch","$env:USERPROFILE\.claude\skills\shared\references\serve-backlog.js","$root" -RedirectStandardOutput "$env:TEMP\backlog-server.log" -RedirectStandardError "$env:TEMP\backlog-server.err"

macOS:

nohup node --watch ~/.claude/skills/shared/references/serve-backlog.js "$root" > /tmp/backlog-server.log 2>&1 &

Don't block waiting for readiness here — starting it in the background and moving straight on to PHASE 2/3 (both pure filesystem/string logic, no server call) is fine. PHASE 4 shows a loading state in the opened window itself while the server comes up, which is a better experience than a synchronous wait-and-report in chat.

PHASE 2: Show result

Scan projects in the projects root (directories containing a .project/ subdirectory). Use $root uit PHASE 1 (al resolved).

Windows:

Get-ChildItem -Path $root -Directory | Where-Object { Test-Path "$($_.FullName)\.project" } | Select-Object -ExpandProperty Name

macOS:

for d in "$root"/*/; do [ -d "$d/.project" ] && basename "$d"; done

Show output:

Server:  http://localhost:9876

Projects:
  - {project-name} → http://localhost:9876/{project-name}                  (dashboard)
                     http://localhost:9876/{project-name}/backlog          (kanban)
                     http://localhost:9876/{project-name}/review/{entity}  (design review)
  - ...

If no projects are found, hint toward /project-add or /project-plan.

If AUTO_INSTALLED=true (from PHASE 0), add one line: "Background service wasn't installed yet — set it up automatically (starts on its own from now on at login)." If it was SKIPPED: <reason>, add: "Background service auto-install skipped ({reason}) — the server still started normally for this session; run /project-app install-app once {reason is resolved} to set it up."

PHASE 3: Copy link to clipboard

Determine which URL to copy (context-aware):

• If cwd is directly under the projects root and that subdirectory contains .project/ → use http://localhost:9876/{project-name} (dashboard of current project)
• Otherwise → use http://localhost:9876 (server root)

Use $root uit PHASE 1 (al resolved).

Windows (PowerShell):

$cwd = (Get-Location).Path
$url = "http://localhost:9876"
if ($cwd -like "$root\*") {
  $rel = $cwd.Substring($root.Length + 1)
  $project = $rel.Split('\')[0]
  if (Test-Path "$root\$project\.project") { $url = "http://localhost:9876/$project" }
}
Set-Clipboard -Value $url
$url

macOS (bash):

cwd="$PWD"
url="http://localhost:9876"
if [[ "$cwd" == "$root"/* ]]; then
  rel="${cwd#$root/}"
  project="${rel%%/*}"
  [ -d "$root/$project/.project" ] && url="http://localhost:9876/$project"
fi
printf '%s' "$url" | pbcopy
echo "$url"

Show below the projects output:

Link copied: {url}

PHASE 4: Open app window

Always runs (unless argument was stop, which already exited above). Reuse $url from PHASE 3 — the same context-aware URL (cwd under a project with .project/ → that project's dashboard; otherwise the index http://localhost:9876). Use $COLD_START from PHASE 1.

If $COLD_START=true: open a loading state instead of $url directly — the server may take a second or two to boot. Point the ad-hoc --app= window (or default browser, if no app-capable browser is found) at the local loading page, which polls the server and redirects itself once ready:

loading_url="file://$HOME/.claude/skills/shared/references/loading.html?url=$(python3 -c "import urllib.parse,sys; print(urllib.parse.quote(sys.argv[1]))" "$url")"

Use $loading_url in place of $url everywhere below when $COLD_START=true.

macOS — prefer the installed PWA if present (only when $COLD_START=false — the installed app always opens its fixed start_url, so it can't show the loading page; on a cold start use the ad-hoc window below instead so the loading page can be shown, even if the PWA is installed). With install-app (PHASE 5) set up, the LaunchAgent keeps the server warm at all times, so $COLD_START is false on nearly every run — this installed-PWA branch is the normal path, not a fallback. $COLD_START=true now only happens without the LaunchAgent (e.g. before running install-app, or after a manual kill that bypassed stop):

An ad-hoc open -na "Brave Browser" --args --app=... window runs inside that browser's regular application bundle, so it shares its Dock icon — minimizing it and clicking the Dock icon later can bring up a plain browser window instead of restoring it, which is confusing. The installed PWA (via the browser's "Install app" prompt) is a real, separate .app bundle with its own bundle ID and Dock icon — native minimize/restore, no ambiguity.

Browser preference order is Brave → Chrome → Edge (matches this setup's actual daily browser — adjust if that changes). A PWA installed in Brave lands in ~/Applications/Brave Browser Apps.localized/, Chrome's in ~/Applications/Chrome Apps.localized/, Edge's in ~/Applications/Microsoft Edge Apps.localized/ — check all three, in preference order, since the app could be installed in any of them:

installed_app=""
if [ "$COLD_START" = false ]; then
  for appdir in "Brave Browser Apps.localized" "Chrome Apps.localized" "Microsoft Edge Apps.localized"; do
    installed_app=$(find "$HOME/Applications/$appdir" -maxdepth 1 -iname "*Project Board*.app" 2>/dev/null | head -1)
    [ -n "$installed_app" ] && break
  done
fi
if [ -n "$installed_app" ]; then
  open -a "$installed_app"
else
  target="$url"
  [ "$COLD_START" = true ] && target="$loading_url"
  opened=false
  for app in "Brave Browser" "Google Chrome" "Microsoft Edge"; do
    if [ -d "/Applications/$app.app" ]; then
      open -na "$app" --args --app="$target"
      opened=true
      break
    fi
  done
  if [ "$opened" = false ]; then
    open "$target"
  fi
fi

Note: the installed-app path opens the PWA's start_url (the index) — it can't be pointed at $url directly, since open -a doesn't pass a URL through to an already-scoped app reliably. That's fine on a warm start: scope is /, so the project's dashboard/backlog is one click away inside the same app window. If $installed_app is empty (not installed yet, or cold start), fall back to the --app= window, and mention in the report that installing once (click the install icon in the address bar on $url) fixes the Dock/minimize behavior for good.

Windows (PowerShell):

$loadingUrl = "file://$env:USERPROFILE\.claude\skills\shared\references\loading.html?url=$([uri]::EscapeDataString($url))"
$target = if ($COLD_START) { $loadingUrl } else { $url }
$candidates = @(
  "$env:ProgramFiles\Google\Chrome\Application\chrome.exe",
  "${env:ProgramFiles(x86)}\Google\Chrome\Application\chrome.exe",
  "$env:ProgramFiles\Microsoft\Edge\Application\msedge.exe",
  "${env:ProgramFiles(x86)}\Microsoft\Edge\Application\msedge.exe",
  "$env:ProgramFiles\BraveSoftware\Brave-Browser\Application\brave.exe",
  "${env:ProgramFiles(x86)}\BraveSoftware\Brave-Browser\Application\brave.exe"
)
$browser = $candidates | Where-Object { Test-Path $_ } | Select-Object -First 1
if ($browser) {
  Start-Process -FilePath $browser -ArgumentList "--app=$target"
} else {
  Start-Process $target
}

Report:

App window opened: {url}

If $COLD_START was true, note that the server was just started and the window shows a loading state until it's reachable. If $installed_app was used, note that too. Otherwise (ad-hoc --app= window), add a one-line tip: click "Install app" / the install icon in the browser's address bar on $url once — that installs a real .app with its own icon and Dock/Launchpad/ Start entry, so minimize/restore works correctly and future /project-app runs auto-detect and use it. If none of the app-capable browsers were found, note that a normal tab was opened instead.

PHASE 5: Install app (argument install-app, macOS + Windows)

One-time (or re-run-to-update) setup — after this, /project-app itself is no longer needed for everyday use; the server is always warm in the background and the installed PWA is the one Dock/taskbar icon.

macOS:

Todo: Read .claude/skills/project-app/references/install-app-macos.md and follow it exactly (LaunchAgent setup, old-launcher removal, PWA install/pin — all as one Bash invocation per step, per the Execution rule above).

Windows:

Todo: Read .claude/skills/project-app/references/install-app-windows.md and follow it exactly (Scheduled Task setup, PWA install, taskbar pin — one PowerShell invocation per step, per the Execution rule above). Unlike the macOS doc, the taskbar-pin step is a manual instruction for the user, not a script — Windows blocks programmatic taskbar pinning since Win10.
