From 0d7d3899e37ff1217d3474a9e7848549667f8bda Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 19 Apr 2026 06:30:48 +0800 Subject: [PATCH] test(context-skills): widen assertion surface to transcript + tool outputs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 4th paid run showed the agent often stops after a tool call without producing a final text response. result.output ends up as empty string (verified: {"type":"result", "result":""}). String-based regex assertions couldn't find evidence of the work that did happen — NO_CHECKPOINTS echoes, filename listings, bash outputs — because those live in tool_result entries, not in the final assistant message. Added fullOutputSurface() helper: concatenates result.output + every tool_use input + every tool output + every transcript entry. Switched the 3 failing tests (empty-state, list-current, list-all) and the flaky legacy-compat test to this broader surface. The 4 stable-passing tests (routing, fragment-match, roundtrip, list-delegates) untouched — they worked because the agent DID produce text output. Pattern mirrors the autoplan-dual-voice test fix: "don't assert on the final assistant message alone; the transcript is the source of truth for what actually happened." Expected outcome: - empty-state: NO_CHECKPOINTS echo in bash stdout now visible - list-current-branch: filename timestamp prefix visible via find output - list-all-branches: 3 filename timestamps visible via find output - legacy-compat: stable pass regardless of agent's text-response choice --- test/skill-e2e-context-skills.test.ts | 60 ++++++++++++++++++++------- 1 file changed, 45 insertions(+), 15 deletions(-) diff --git a/test/skill-e2e-context-skills.test.ts b/test/skill-e2e-context-skills.test.ts index ae00ce8a..08f3692f 100644 --- a/test/skill-e2e-context-skills.test.ts +++ b/test/skill-e2e-context-skills.test.ts @@ -104,6 +104,30 @@ function skillCalls(result: { toolCalls: Array<{ tool: string; input: any }> }): .filter(Boolean); } +// Build a broader assertion surface: final assistant message + every tool +// input and output.
