feat: record-video returns frame sheets and change numbers an agent can read, around one action in one command - #3377
Merged
Conversation
…e check they serve
Agents pick a skill from its one-line description and read the body only
afterwards. An agent verifying a fix that stops a method from being called
never reached for pause-point or record-video: pause-point read as a
debugger ("Breakpoint-like: pause"), its trace mode and the meaning of zero
hits were only in the parameter table, record-video was framed as the step
after a screenshot, and run-tests claimed "change verification" outright,
so passing tests ended the check.
pause-point now leads with counting hits in trace mode, names the screenshot
of the paused frame, and says it confirms whether a code path ran after a
fix. record-video is for verifying motion after a change. run-tests drops
"change verification" and points at pause-point and record-video for the
behavior tests do not exercise.
The pause-point body sat 31 bytes under the 8,000-byte cap, so its target
forms and timeout notes move to references/troubleshooting.md, which already
covers timeouts and hot reload. The catalog descriptions and the generated
skill copies follow.
…nly in the generated copies The previous commit left the source frontmatter on the old wording while the copies under .claude/ and .agents/ already carried the new one, so the next regeneration would have reverted it and Tool Settings, which reads the source, would have shown the old text. The layout test that pins the description's opening words follows.
…can read, and accepts a mark (#3372)
…, even with Unity closed (#3375)
main gained only the squash of the skill-description fix, whose tree matches the head this branch already merged, so the merge keeps this branch's tree unchanged.

Qualify the burst-sheet guarantee.
The output reference omits BurstSheetPath and BurstFrames when fewer than two frames were captured or when no frame changed and no mark exists. This ADR states that every stopped recording returns a burst sheet. Add the omission conditions so the decision matches the response contract.
