Port resource tools once V2 tool plugin settles

[opencode-agent]

TODO

Port resource tools once the V2 tool plugin API settles.

Context

• Current v2 does not yet have the planned plugin tool surface (ctx.tool.transform(...) / transform-backed tool registry).
• There is open architecture/prototype work around plugin/session/tool patterns (for example the plugin-patterns plan), but resource tools should wait until that API shape is stable.

Done when

• The settled V2 plugin tool API is identified.
• Resource tools are registered through that API instead of the current transitional path.
• Any affected tests/docs are updated.

Tracker update from V2 TODO LIST audit (2026-07-02):

Still blocked on the V2 tool/plugin architecture settling.

Relevant current work:

• refactor(plugin): move tool implementation to plugin #34665 merged: core Tool API moved to plugin package boundary.
• feat(plugin): add tool result content API #34709 open: tool result content/progress API.
• refactor(core): bridge plugin runtime in app builder #34805 open draft: plugin runtime bridge in app builder.
• Port commands to V2 #34685 / [FEATURE]: Implement V2 session.command API #34429: command execution path remains relevant for prompt/resource command surfaces.

Recommendation: do not start resource-tool porting until #34709/#34805 land and Aiden/Kit confirm the command/tool-plugin sequencing is stable.

Update: #34956 migrates the remaining built-in tools to internal plugins. Resource tools are still a separate follow-up, but this reduces the blocker around built-in tools dogfooding the plugin registration surface.
