Summary
The bundled document-extract plugin loads but registers zero capabilities after upgrading to 2026.6.1, making DOCX and PDF file reading non-functional.
Steps to reproduce
tools is [], and shape is "non-capability"
Expected behavior
The document-extract plugin registers its PDF/DOCX extraction capability at gateway startup and appears in the gateway startup plugins list, allowing the agent to read local document files.
Actual behavior
Plugin shows status "loaded" in openclaw plugins inspect but registers zero capabilities: capabilityCount: 0, tools: [], shape: "non-capability". Plugin is absent from gateway startup log. Agent cannot read DOCX or PDF files. Began after upgrading from 2026.5.27 to 2026.6.1.
OpenClaw version

Operating system

Logs, screenshots, and evidence
Impact and severity
Affected: any agent using the bundled document-extract plugin on 2026.6.1
Severity: High — blocks all DOCX and PDF file reading
Frequency: Always (100% reproducible)
Consequence: Agent cannot process any document files; workaround requires manually attaching files via Telegram
Additional information
Last known good version: 2026.5.27
First known bad version: 2026.6.1
Plugin origin is "bundled" — cannot be reinstalled independently.
contracts.documentExtractors declares ["pdf"] but capabilityCount is 0 and tools is empty, suggesting capability registration silently fails during gateway startup.
