Plugin tools registered but not visible to agent sessions

[neocody]

Problem

ClawVoice tools are registered via api.registerTool() with registrationMode=full, but they do not appear in agent sessions. The agent (Pip) confirms it has zero clawvoice_* tools despite the plugin loading and initializing successfully.

Evidence

Gateway logs show tools registering:

[clawvoice] registerTool: clawvoice_call (registrationMode=full)
[clawvoice] registerTool: clawvoice_hangup (registrationMode=full)
...9 tools total

But when asked directly, the agent says:

Q: Do you have a tool called clawvoice_call?
A: NO

Config

• plugins.allow includes "clawvoice"
• plugins.entries.clawvoice.enabled: true
• plugins.installs.clawvoice has proper provenance
• tools.alsoAllow includes all tool names
• tools.profile: "full"
• OpenClaw version: 2026.3.23-2

What was tried

1. tools.alsoAllow: ["group:plugins"] — no such group exists
2. tools.alsoAllow: ["clawvoice"] (plugin ID)
3. tools.alsoAllow: ["clawvoice_call", ...] (explicit tool names)
4. Proper openclaw plugins install with provenance
5. /new session reset
6. Gateway restart
7. Removing init guard
8. All combinations above

Suspected root cause

The Pi embedded session calls resolvePluginTools which calls getActivePluginRegistry(). The gateway does NOT call setActivePluginRegistry — it only calls pinActivePluginHttpRouteRegistry. So the Pi session falls through to loadOpenClawPlugins independently. Either the independent load doesn't find ClawVoice's tools, or there's a registry object mismatch.

Workaround

The CLI (openclaw clawvoice call) works. Agent uses exec tool to shell out.
