feat: sessions outline names tools on tool-only turns (v0.20.0)#50
Merged
Conversation
A pure tool-call assistant turn -- the agent acted without narrating -- rendered a content-free "tools..." in the sessions rail, dead exactly when the agent was doing the work. It now names what it did in the conversation folds' own vocabulary: Bash, Read, skill ccx, mcp github, Task -- deduped and capped at three with a +N remainder. A thinking-only turn reads "thinking...", a genuinely empty one "(no text)". The rail should narrate the agent's actions; that is the whole point of the trace. turnToolLabel in src/ui.ts; two dom-stub tests pin the single-tool and multi-tool-capped cases. CHANGELOG 0.20.0 also records the ui.md/TASTE.md reconciliation merged in #49 -- 0.19.0 was the last npm release, so this is the release unit that ships both.

turnToolLabel(turn)in src/ui.ts maps each tool_use block to the conversation folds' own vocabulary -- subagent spawns toTask,Skilltoskill · <name>,mcp__*tomcp · <server>, everything else to the plain tool name -- deduped, capped at three with a+Nremainder.!textfallback in the outline now prefers that label; a thinking-only turn readsthinking…, a genuinely empty one(no text)-- no more asserting "tools" when there were none.Ships in src/ui.ts, so users get the improved rendering (unlike the docs-only #49). CHANGELOG 0.20.0 records both this and the ui.md/TASTE.md reconciliation from #49, since 0.19.0 was the last npm release.
479 tests pass; binary compiles.
