/reload-plugins doesn't rebuild slash-command index

[reggiechan74]

Description

/reload-plugins loads skills into the model context (system reminder) but does not rebuild the / command parser index (autocomplete + direct invocation). This means plugin changes made mid-session (install, uninstall, marketplace edits) won't register as / commands until Claude Code is fully restarted.

The output message — Reloaded: 23 plugins · 68 skills · 34 agents — implies a full reload occurred, which is misleading.

Repro

1. Start a fresh Claude Code session
2. Install a new plugin mid-session: /plugin install fabula-nf@sefirot-marketplace
3. /reload-plugins → reports skills loaded successfully
4. Type /fabula-nf:essays → "Unknown skill"
5. The skill IS available via the Skill tool (model can invoke it) and appears in the system reminder
6. Exit and restart Claude Code
7. Type /fabula-nf:essays → works

Also reproducible in reverse:

1. Start session with brando installed → /brando:analysis works
2. Uninstall brando mid-session → /reload-plugins
3. /brando:brand-audit → still works (stale command index)
4. Restart → brando commands correctly gone

Expected

/reload-plugins rebuilds the command index so / autocomplete and direct invocation reflect the current plugin state — or the output message indicates a restart is required.

Actual

Two separate registration systems exist:

• Model-facing (system reminder): rebuilt on /reload-plugins ✓
• Command parser (/ autocomplete + direct invocation): only built on session start ✗

Environment

• Claude Code 2.1.81
• Linux (OrbStack)
