Coding-agent plugins capped a tool part's `tool_output` at 2000 chars before
POSTing it to `/api/v1/sessions/{id}/messages`. That cap sits below the server's
own externalization threshold (`tool_output_externalization.threshold_chars`,
default 20000), so output in the 2k-20k band was destroyed for no reason and
anything larger never reached `ToolResultStore` - leaving `tool_output_ref`
permanently empty and the `/tool-results` read-back path unusable.
Raise the `captureToolMaxChars` default to 1000000 (a guard against pathological
payloads, not a truncation policy) and lift the opencode/pi clamps that would
otherwise pin it back to 20000. claude-code had no knob at all - two hardcoded
`TOOL_OUTPUT_PART_MAX_CHARS = 2000` constants - so it gains the same config
entry and both capture scripts now read it.
Also stop pi from sending tool output twice: for a tool-only payload the
rawText-derived text part re-rendered the same output the tool part carries.
* feat(plugins): align opencode and pi memory integrations
* fix(installer): tolerate missing optional harness CLIs
* fix(installer): install opencode file wrapper
* fix(opencode): import path for logger initialization
* fix(installer): register pi extension after copy
* feat(plugins): use MCP for opencode integration
* docs: move OpenCode and pi integrations to dedicated pages
Promote the OpenCode plugin and pi extension out of the community-plugins
page into their own numbered agent-integrations pages (10-opencode, 11-pi,
en + zh), update the overview routing table, and refresh the OpenCode image
cards to the hybrid MCP architecture (unified installer, openviking_* MCP
tools, ovcli.conf credentials).
* docs: bare TOS installer commands and reference more examples
Drop --harness from TOS-mirror install commands (image cards use the bare
installer URL, matching the claude-code/codex cards); add Open WebUI tool
server and an examples/ pointer to the community-plugins page (en + zh).
* docs: bare TOS installer commands across agent-integration pages
TOS-mirror install commands carry no flags anywhere; the installer wizard
asks for source, harnesses, language, and credentials.
