Environment

• OpenClaw: 2026.5.2
• Node.js: v22.22.2
• OS: Linux (Ubuntu)

Problem Description

After enabling active-memory plugin, every time it tries to run a sub-agent during the before_prompt_build phase, it fails with:

No callable tools remain after resolving explicit tool allowlist 
(agents.main.tools.allow: *, feishu_bitable_app, ...; runtime toolsAllow: memory_search, memory_get); 
no registered tools matched.

Steps to Reproduce

1. Enable active-memory in openclaw.json
2. Restart gateway
3. Send any message

Expected Behavior

active-memory should search memory and inject context before each reply, but the sub-agent fails to find memory_search/memory_get tools.

Error Log

active-memory: agent=main session=... activeProvider=minimax activeModel=MiniMax-M2.7 start timeoutMs=25000 queryChars=1168
embedded run failover decision: surface_error, stage=prompt
lane task error: lane=main durationMs=4229 error="Error: No callable tools remain after resolving explicit tool allowlist (...; runtime toolsAllow: memory_search, memory_get); no registered tools matched."
active-memory: agent=main session=... failed error=No callable tools remain after resolving explicit tool allowlist (...; runtime toolsAllow: memory_search, memory_get); no registered tools matched.

Analysis

• memory-core plugin is enabled and registers memory_search and memory_get tools
• active-memory uses bootstrapContextMode: lightweight to launch sub-agent
• Sub-agent toolsAllow correctly includes memory_search and memory_get
• But sub-agent reports "no callable tools matched"

Configuration

• memory-core: enabled
• active-memory: enabled
• lossless-claw: enabled
• memory-wiki: enabled
• All plugins updated to latest versions

Notes

Same configuration worked in older versions, problem appeared after upgrade to 2026.5.2.
