Skill HUD setup

The claude-skill-hud plugin's hooks (which log skill invocations) are already active now that the plugin is installed. The one piece a plugin cannot wire up automatically is the main session status line — that's a plain user-level settings.json field, not a plugin-managed component, so it needs to be written once, explicitly.

This skill's job: add that one statusLine entry, without touching anything else already in the user's settings.

Resolved paths for this install

These paths were substituted into this skill's content when it loaded, so they're already correct for wherever this plugin is installed on this machine:

• Plugin root: ${CLAUDE_PLUGIN_ROOT}
• Persistent data directory: ${CLAUDE_PLUGIN_DATA}
• Status line script: ${CLAUDE_PLUGIN_ROOT}/scripts/statusline.sh

Steps

1. Read ~/.claude/settings.json. If it doesn't exist, treat it as {}.

2. Check the existing statusLine key, if any:

   • If it's already set to a command containing scripts/statusline.sh from this plugin's root, the HUD is already configured — tell the user this and stop, no changes needed.
   • If a different statusLine is already configured (the user has their own custom one), stop and ask the user how they want to proceed. Do not silently overwrite it. Options: replace it, or skip HUD setup and let the user merge it manually.
   • If no statusLine key exists, proceed to step 3.

3. Add this exact block to the settings JSON, merging it in alongside any other existing top-level keys (do not remove or reorder unrelated keys):

   "statusLine": {
     "type": "command",
     "command": "CLAUDE_PLUGIN_DATA=\"${CLAUDE_PLUGIN_DATA}\" \"${CLAUDE_PLUGIN_ROOT}/scripts/statusline.sh\"",
     "refreshInterval": 2
   }
   

   The CLAUDE_PLUGIN_DATA=... prefix is required: the main status line runs outside the plugin hook/MCP substitution system, so this is the one place that env var has to be set explicitly rather than relying on automatic injection. refreshInterval is a safety net on top of the normal event-driven refresh (after each assistant message) — it forces a re-render every 2 seconds so the HUD can't visibly linger stale.
