+description: >
+  Installs or updates the Zulip platform plugin for any Hermes agent from the
+  canonical zulip-platform-plugins repo. Ensures the agent runs the latest
+  adapter with all Zulip chat fixes (_strip_html, streaming, event recovery).
+  Runs a post-install verification and sends a relay success signal.

+# Hermes Zulip Plugin — Install & Repair
+
+Single-shot function that pulls the latest zulip-platform plugin from the
+canonical git repo, installs it to the correct Hermes bundled plugin path,
+verifies the installation, and signals completion.
+
+Distinct from `hermes-zulip-restore`: this contract only touches the plugin
+layer. It does NOT verify env credentials, restart the gateway, or validate
+the live Zulip connection. Use `hermes-zulip-restore` for full connectivity
+recovery.
+
+## Parameters
+
+| Param | Type | Required | Default | Description |
+|-------|------|----------|---------|-------------|
+| `target` | string | yes | — | Agent name: `mumuni`, `tanko`, or `koby` |
+| `branch` | string | no | `feat/zulip-streaming` | Git branch to pull (overridable for pinning) |
+
+## Maintains
+
+- plugin_installed: bool — Whether all three adapter files exist at the bundled path
+- plugin_version: string — Git commit SHA of the installed version
+- strip_html_present: bool — Whether `_strip_html` fix is in the installed adapter
+- signal_sent: bool — Whether relay success message was dispatched
+
+### Postconditions
+
+- All three adapter files (`__init__.py`, `adapter.py`, `plugin.yaml`) present in `<HERMES_HOME>/hermes-agent/plugins/platforms/zulip/`
+- `_strip_html` function exists in `adapter.py` (slash-command fix, commit `55ca15d`+)
+- Installed version matches HEAD of the requested branch
+- Relay success signal sent to Hermes agent's inbox
+
+## Requires
+
+- SSH access to target host (direct or via amdpve for CTs)
+- Git repo at `https://git.sysloggh.net/SyslogSolution/zulip-platform-plugins.git`
+- Python 3 with `httpx` installed on target
+
+## Live-State Fields
+
+| Host | CT | Proxmox | IP (direct) | Hermes Home | User |
+|------|-----|---------|-------------|-------------|------|
+| Mumuni | CT114 | — | 192.168.68.123 | /root/.hermes | root |
+| Tanko | CT112 | amdpve | 192.168.68.122 | /home/jerome/.hermes | jerome |
+| Koby | CT111 | amdpve | 192.168.68.129 | /root/.hermes | root |
+
+| Field | Value | Trust |
+|-------|-------|-------|
+| Git repo | `https://git.sysloggh.net/SyslogSolution/zulip-platform-plugins.git` | ✅ Verified |
+| Default branch | `feat/zulip-streaming` | ✅ Verified |
+| Bundled adapter path | `<HERMES_HOME>/hermes-agent/plugins/platforms/zulip/` | ✅ Verified |
+| Adapter files | `__init__.py`, `adapter.py`, `plugin.yaml` | ✅ Verified |
+| Strip-html commit | `55ca15d` (minimum) | ✅ Verified |
+
+## Execution
+
+### Step 1: Resolve Target
+
+Map `target` to host, CT ID, hermes_home, and user from the live-state table.
+For CT112 and CT111, route through `ssh root@amdpve` then `pct exec <id>`.
+
+### Step 2: Pull Latest Plugin Source
+
+On the target host:
+
+```bash
+# Ensure deploy scratch space
+mkdir -p /tmp/zulip-deploy
+cd /tmp/zulip-deploy
+
+# Clone or pull
+if [ -d zulip-platform-plugins ]; then
+  cd zulip-platform-plugins
+  git fetch origin
+  git checkout {{branch}}
+  git pull origin {{branch}}
+else
+  git clone --branch {{branch}} \
+    https://git.sysloggh.net/SyslogSolution/zulip-platform-plugins.git
+  cd zulip-platform-plugins
+fi
+
+# Capture installed version
+INSTALLED_SHA=$(git rev-parse HEAD)
+echo "Installed SHA: $INSTALLED_SHA"
+
+# Verify we're at HEAD
+HEAD_SHA=$(git rev-parse origin/{{branch}})
+if [ "$INSTALLED_SHA" = "$HEAD_SHA" ]; then
+  echo "At latest commit on {{branch}}"
+else
+  echo "WARNING: not at HEAD — $INSTALLED_SHA vs $HEAD_SHA"
+fi
+```
+
+### Step 3: Install Plugin Files
+
+```bash
+# Ensure target directory exists
+mkdir -p {{hermes_home}}/hermes-agent/plugins/platforms/zulip
+
+# Copy adapter files
+cp plugins/platforms/zulip/adapter.py \
+   plugins/platforms/zulip/__init__.py \
+   plugins/platforms/zulip/plugin.yaml \
+   {{hermes_home}}/hermes-agent/plugins/platforms/zulip/
+
+# Fix ownership (Tanko only — runs as jerome user)
+[ "{{target}}" = "tanko" ] && chown -R jerome:jerome \
+  {{hermes_home}}/hermes-agent/plugins/platforms/zulip/
+
+echo "Plugin files installed"
+```
+
+### Step 4: Verify Installation
+
+```bash
+# Check all three files exist
+for f in __init__.py adapter.py plugin.yaml; do
+  if [ -f "{{hermes_home}}/hermes-agent/plugins/platforms/zulip/$f" ]; then
+    echo "✅ $f present"
+  else
+    echo "❌ $f MISSING"
+    exit 1
+  fi
+done
+
+# Verify _strip_html fix
+grep -q "_strip_html" {{hermes_home}}/hermes-agent/plugins/platforms/zulip/adapter.py \
+  && echo "✅ _strip_html fix present" \
+  || echo "❌ _strip_html MISSING — plugin may be stale"
+
+# Show installed plugin.yaml version
+grep "^version:" {{hermes_home}}/hermes-agent/plugins/platforms/zulip/plugin.yaml || true
+```
+
+### Step 5: Send Relay Success Signal
+
+On the Abiba host (local), dispatch a relay message to the target agent:
+
+```
+ra-h-os-createRelayNode:
+  title: "Zulip plugin updated — {{target}}"
+  source: |
+    Plugin installed from {{branch}} @ {{INSTALLED_SHA}}
+    All 3 adapter files verified at {{hermes_home}}/hermes-agent/plugins/platforms/zulip/
+    _strip_html fix: PRESENT
+    Timestamp: {{timestamp}}
+
+  description: "hermes-zulip-plugin completed for {{target}} — plugin layer healthy"
+```
+
+### Step 6: Report
+
+Compile results into a single status block:
+
+| Field | Value |
+|-------|-------|
+| Target | `{{target}}` |
+| Branch | `{{branch}}` |
+| Commit SHA | `{{INSTALLED_SHA}}` |
+| Files installed | `__init__.py`, `adapter.py`, `plugin.yaml` |
+| `_strip_html` | `{{present|missing}}` |
+| Signal sent | `{{yes|no}}` |
+
+## Known Failure Modes
+
+| Symptom | Root Cause | Recovery |
+|---------|-----------|----------|
+| Git clone fails | No network or repo unreachable | Check VPN/network, verify repo URL |
+| Permission denied on copy | Wrong user for target | Use correct user (jerome for Tanko, root for others) |
+| `_strip_html` missing after install | Branch doesn't include commit `55ca15d` | Switch to `feat/zulip-streaming` branch |
+| Plugin files missing after copy | Target directory doesn't exist | Ensure `mkdir -p` ran successfully |
+| Relay signal fails | MCP bridge unreachable | Signal manually via `ra-h-os-createRelayNode` |
+
+## Edge Differences from hermes-zulip-restore
+
+| Concern | hermes-zulip-restore | hermes-zulip-plugin |
+|---------|---------------------|---------------------|
+| Env credential check | ✅ Full ZULIP_* verification | ❌ Out of scope |
+| Gateway restart | ✅ Restarts the gateway process | ❌ Out of scope |
+| Live connection test | ✅ Validates `zulip.state = connected` | ❌ Out of scope |
+| Plugin deploy | ✅ Includes deploy as one step | ✅ Primary purpose |
+| Version tracking | ❌ Implicit | ✅ Explicit SHA capture |
+| Signal dispatch | ❌ None | ✅ Relay message to target |
+
+For full connectivity recovery after a plugin install, chain this contract
+with `hermes-zulip-restore` (skip its Step 2 to avoid redundant deploy).
