Keep getting an ongoing error using Devstral-Medium.

Here is the relevent snipper of the conversation.

Read src/phase3_vulnerability_assessment.py

"""
Phase 3: Vulnerability Assessment and PR Simulation
Analyzes scan results and generates simulated pull request remediation proposals
"""

import logging

Now I understand how the simulated PRs are generated. The issue is that the current implementation is using generic fixes that just add comments instead of actual code fixes. Let
me modify the generate_fix_for_vulnerability method to use the fix templates properly.

Let me check the current fix templates to understand what we have available:
Build devstral-medium-2507 (07:54 AM)

Read src/phase3_vulnerability_assessment.py (limit=100, offset=40)

        self.fix_templates = {
            "insecure_random_python": {
                "patterns": [r"random\.random\(\)", r"random\.randint\(", r"random\.choice\("],
                "fixes": {
                    r"random\.random\(\)": "secrets.token_hex(16)",
                    r"random\.randint\(([^)]+)\)": r"secrets.randbelow(\1)",

Now let me check the generate_fix_for_vulnerability method to understand how it's currently working:
Build devstral-medium-2507 (07:54 AM)

Read src/phase3_vulnerability_assessment.py (limit=240, offset=180)

            elif "command" in vulnerability_type:
                return "command_injection"
            else:
                return "generic_vulnerability"

    def generate_fix_for_vulnerability(self, scan_result: Dict, vuln_type: str) -> Optional[Tuple[str, List[str], str, str]]:

I can see the issue now. The problem is in the generate_fix_for_vulnerability method. It's trying to use the fix templates, but it's only applying the first matching pattern and
then breaking the loop. Also, the generic fixes are just adding comments instead of actual fixes.

Let me modify the code to properly apply all the fix patterns and ensure we're using the actual code fixes from the templates.

AI_APICallError: Unexpected role 'user' after role 'tool'

This is occurring every time Opencode tries to make a code edit using Devstral.

This issue might be a duplicate of existing issues. Please check:

  • #526: Persistent tool call errors with Deepseek v3 and Devstral - reports similar tool errors specifically with Devstral model
  • #2720: AI_APICallError about tool_use blocks found without corresponding tool_result blocks - describes the exact same "AI_APICallError" and tool role sequence issues you're experiencing

The "AI_APICallError: Unexpected role 'user' after role 'tool'" error you're seeing appears to be related to the same underlying tool calling and message formatting issues reported in these other tickets.

Feel free to ignore if none of these address your specific case.

@agileandy if it is timing out frequently are you running it locally? Have you tried increasing timeout? If u share your opencode.json I can show u how

I'm running this through the Mistral API. I'll try and find the timeout settings and play around.

@agileandy this is how you can override timeout (it is in ms):

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "mistral": {
      "options": {
        "timeout": 600000 // 10 minutes
      }
    }
  }
}
