Resume and /tree restored exactly the tools the branch recorded, so extension
tools registered later stayed inactive. Registered extension tools that the
branch never added or removed are now activated unless they use
defaultActive: false. The whole branch is searched, so tools removed before a
compaction stay inactive. Also fixes the /tree case from #11075.
closes#11062
The SDK always passed initial tools, so the constructor never restored the
loadout recorded in the transcript, and resumed sessions dropped tools activated
during the session. Sessions that use the default tools now restore the recorded
loadout, with --tools +name/-name entries applied to it.
fixes#10785
A --tools list of only +name/-name entries changes the default tool
selection like the defaultTools setting, e.g. pi -t +codemode. Mixed
lists and patterns in modifiers are rejected, and /reload keeps tools
removed with -name removed.
When the session's initial tools come from defaultTools, /reload activates
names added to the resolved selection. Removals do not deactivate tools, and
explicit --tools/--no-tools/--no-builtin-tools keep overriding the setting.
closes#10245
Entries of only +name/-name modify the inherited tool selection, so
"defaultTools": ["+codemode"] enables codemode without repeating the
defaults. Project entries layer on top of user settings. Document how to
enable codemode without MCP and how to use classifier models from it.
