The Thought Stream captured only `process:thinking-chunk`, so it showed an
agent's reasoning but never its actions. Tool calls do render in the chat
transcript, but only when a tab's `showThinking` is on - and an Auto Run
spawns as `{sessionId}-batch-{ts}` with no AI tab at all, so it has no
transcript for them to live in. Net effect: no surface anywhere showed what
an Auto Run agent was actually doing while it burned tokens.
Tool calls now stream into the Thought Stream interleaved with the reasoning,
each reduced to ONE short plain-language line:
3:42:07 PM * Ran npm test
3:42:04 PM v Read src/renderer/components/ThoughtStreamPanel.tsx
3:42:01 PM v Searched for THOUGHT_BLOCK_GAP_MS
3:41:58 PM ! Edited src/renderer/constants/themes.ts
Ordering is the product here, so it is structural rather than sorted. A
session's buffer is ONE chronological array holding both kinds of event in
arrival order, and `buildActivityFeed` walks it once: consecutive thinking
coalesces into a block, and a tool call CLOSES the open block so the
reasoning that followed it starts a new one below. Keeping thoughts and
tools in two lists and merging at display time cannot express this - a block
carries a single timestamp, so a tool call that happened mid-block has
nowhere to go and surfaces after reasoning that actually followed it.
A completion merges into the entry its start created, in place, keeping both
its slot and its start timestamp: the feed lists actions, not state
transitions, and a long build does not leapfrog the reasoning that happened
while it ran. Matching is by `toolCallId`, else by newest still-running call
of the same name in the same tab (the rule the transcript already uses for
providers that send no id).
- `utils/toolActivityLabel.ts` (new): normalizes tool names across Claude
Code, OpenCode, Codex, Copilot, and MCP onto plain English. Unknown tools
degrade to `Used <name>` rather than vanishing.
- `useThoughtStreamToolListener` (new): taps `process:tool-execution`, scoped
by the same `AUTO_RUN_SESSION_TYPES` set the thinking listener uses and
importing it rather than restating it - the two feed one timeline, so any
divergence would interleave one stream's actions with another's reasoning.
- Panel renders tool rows as plain text (a shell command is not markdown),
search matches the rendered line and the raw tool name, and the header
counts thoughts and actions separately - a climbing action count against
flat reasoning is what a loop looks like.
Capture stays ambient, so opening the panel on a run that has been wedged for
ten minutes shows those ten minutes.
Closes #1312

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to A tool completion with an asymmetric call ID can appear as a duplicate action in the Thought Stream, leading to inaccurate activity rows and counts; the UI wording and one documentation lint issue also need cleanup.

Greptile SummaryThe PR extends Auto Run’s Thought Stream with a single interleaved timeline for reasoning and normalized tool activity.
Confidence Score: 4/5The PR should not merge until failed Codex shell actions stop appearing as successful in the new supervision feed. Codex preserves failed command information in the tool state but reports a completed status that the new listener converts into a success glyph; the store also has a non-blocking character-accounting drift when completion merges enrich labels.

There was a problem hiding this comment.
When a Codex command_execution finishes with a failed status or nonzero exit code, its parser reports completed while retaining the failure details separately, and this listener converts that status into a successful action. The Thought Stream consequently shows a check mark for a failed shell command instead of the warning icon operators rely on to supervise Auto Runs.

When a completion replaces an empty-target label with a descriptive target, the merged entry becomes longer but the buffer retains prev.chars. Repeated merges therefore undercount retained content, preventing the character budget and trimmed indicator from accurately reflecting the buffered timeline.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Stale "thoughts" wording after the switch to selectActivityCount. Both entry points now read a count that includes tool calls, but the variable name and the tooltip text still describe thoughts only, so a tool-only run reports actions as thoughts.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Fall back to the name match when a completion carries an id the start did not.
The id branch returns -1 as soon as the lookup misses. If a provider omits toolCallId on the start event and sends it on the completion, appendToolActivity appends a second row instead of merging, so one action renders as two rows. Let a finalizing event fall through to the name/tab match, and only accept an entry that carries no conflicting id.
🐛 Proposed fix for the asymmetric-id case
if (toolCallId) {
for (let i = entries.length - 1; i >= 0; i--) {
const event = entries[i];
if (isToolEvent(event) && event.tool.toolCallId === toolCallId) return i;
}
- return -1;
+ // An id that matches nothing can still finish a start the provider sent
+ // WITHOUT an id, so fall through to the name/tab rule below.
}
if (!finalizing) return -1;

const event = entries[i];

isToolEvent(event) &&
event.tabId === tabId &&
event.tool.name === toolName &&

Closes #1312
Problem
The Thought Stream captured only
process:thinking-chunk, so it showed an agent's reasoning but never its actions. Tool calls do render in the chat transcript, but only when a tab'sshowThinkingis on - and an Auto Run spawns as{sessionId}-batch-{ts}with no AI tab at all, souseAgentToolExecutionListener(which writes intoaiTabs[tabId].logs) has nowhere to put them.Net effect for the reporter: no surface anywhere showed what an Auto Run agent was actually doing while it burned tokens.
What this does
Tool calls stream into the Thought Stream interleaved with the reasoning, each reduced to ONE short plain-language line:
A spinner marks a call in flight; a check or a warning marks how it ended. That density is the reporter's stated need: cost control, spotting a loop and interrupting it before it burns more tokens.
This is a fresh pass on #1314, not a rebase
#1314 was closed because its chronology was structurally wrong:
groupThoughtsIntoBlocksignored intervening tool calls, and the feed merged two independently-sorted sequences at display time, assigning each complete thought block its start time. A tool call that happened mid-block could never render between the reasoning chunks surrounding it, so a fast call displayed after the reasoning that actually followed it.The closing note asked for a redesign: "interleave on a single timeline of timestamped events rather than merging two independently-sorted sequences after the fact." That is what this does.
A session's buffer is now one chronological array holding both event kinds in arrival order (
StreamEvent = ThoughtEntry | ToolActivityEntry, discriminated by the presence oftool).buildActivityFeedwalks it once: consecutive thinking coalesces into a block, and a tool call closes the open block so reasoning that arrived after an action starts a new block below it. Ordering is therefore structural - there is no sort that could put a call in the wrong place.groupThoughtsIntoBlocksbecomes a projection of that same walk, so the two views cannot disagree about where a block starts.src/__tests__/.../thoughtStreamStore.test.tspins the exact old failure: a tool call 1ms into a block must still render before the reasoning that followed it.Changes

No rAF/timer coalescing: tool calls arrive per agent action, not per frame.ThoughtStreamPanel.tsxTool rows render as plain text, not markdown - a shell command or glob pattern is full of characters markdown claims, so the renderer would mangle exactly the lines the user is reading. Search matches the rendered line and the raw tool name (searching "Bash" finds a row rendered "Ran npm test"). The header counts thoughts and actions separately: a climbing action count against flat reasoning is what a loop looks like.
