yrenat opened a new issue, #9119:
URL: https://github.com/apache/texera/issues/9119
### What happened?
The agent does not see the result of its earlier tool calls. When a call
fails, the agent does not know why, so it makes the same call again and again.
In `agent-service/src/agent/util/context-utils.ts`, `serializeTask` writes
each past tool call as one line:
```ts
lines.push(`- ${tc.toolName} (${statusAttr})`);
```
It only writes the tool name. The system prompt (`prompts.ts`) says each
call should also have `Summary`, `Output`, or `Error` lines, but these lines
are never added.
Example on `main` with claude-haiku-4.5. Prompt: "Add a Limit operator that
keeps 10 rows, and connect its input to the existing operator op7." (there is
no op7). Every call returned `[ERROR] Source operator "op7" not found`. The
agent made the same `modifyOperator` call 5 times until it hit the step limit.
At turn 3, the agent got this context:
```
### Turn 1
Thought: I'll add a Limit operator that keeps 10 rows and connect it to op7.
- addOperator (succeeded)
### Turn 2
Thought: I can see that you've already successfully added the Limit operator
`op8` ...
- modifyOperator (succeeded)
```
The error message is not there.
Expected: each tool call in the history should include its summary and
output, or the error message if it failed.
**Screenshots**
Step 1, tool call: addOperator returned `[ERROR] Source operator "op7" not
found`.
Step 3, what the agent was given: Turn 1 and Turn 2 only say `(succeeded)`.
There is no error text.
The chat: the agent says "Let me connect it to op7" again and again, until
the step limit (5).
### How to reproduce?
1. Open an empty workflow and create an agent.
2. Send: `Add a Limit operator that keeps 10 rows, and connect its input to
the existing operator op7.`
3. Click "View details" on a later step and look at Input Messages. Past
calls show only `- <tool> (succeeded)`, with no error text. The agent keeps
repeating the call.
