问题描述 · Description

"Let me look at the situation. The user says "Error with building nomadinventory 1.9.0" and attached a screenshot. Interesting - the summary said we were working on v1.7.1, but apparently there's now a v1.9.0 that has build errors. The session summary may be stale relative to actual conversation state — the user mentions 1.9.0, which suggests I may have already produced v1.9.0 in a part of the conversation that got compacted. Wait, the summary is supposed to cover everything... but the user's message references v1.9.0 which isn't in the summary. Perhaps the summary was truncated or the file versions continued past 1.7.1. Either way, I need to:"

Where the issue was noticed: Agent mode, z.ai website, GLM 5.3 Flash.

复现步骤 · Steps to reproduce

1. Go to z.ai website
2. Click agent mode
3. Select GLM 5.3 Flash
4. Send messages until the conversation reaches the point of needing to be compacted, and see if the AI remembers correctly the conversation subject

期望表现 · Expected behavior

实际表现 · Actual behavior

Conversation compacting / summary doesn't cover the whole conversation or the most important parts of it.

No file, test, or entry point is identified. First reproduce the compaction failure in Agent mode with GLM 5.3 Flash on the z.ai website, then trace the relevant summarization path; done means the compacted conversation preserves its subject and important context, including the referenced version.
