From b8265783f30233d623bca28919390e3f3b02c929 Mon Sep 17 00:00:00 2001 From: Felipe Cardoso Date: Wed, 31 Dec 2025 14:43:08 +0100 Subject: [PATCH] fix(agents): prevent issue assignment to terminated agents and cleanup on termination MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes 4 production bugs found via edge case testing: 1. BUG: System allowed assigning issues to terminated agents - Added validation in issue creation endpoint - Added validation in issue update endpoint - Added validation in issue assign endpoint 2. BUG: Issues remained orphaned when agent was terminated - Agent termination now auto-unassigns all issues from that agent These bugs could lead to issues being assigned to non-functional agents that would never work on them, causing work to stall silently. Tests added in tests/api/routes/syndarix/test_edge_cases.py to verify: - Cannot assign issue to terminated agent (3 variations) - Issues are auto-unassigned when agent is terminated - Various other edge cases (sprints, projects, IDOR protection) Coverage: 88% → 93% (1830 tests passing) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- backend/app/api/routes/issues.py | 20 +- backend/app/crud/syndarix/agent_instance.py | 12 +- .../api/routes/syndarix/test_edge_cases.py | 665 ++++++++++++++++++ 3 files changed, 695 insertions(+), 2 deletions(-) create mode 100644 backend/tests/api/routes/syndarix/test_edge_cases.py diff --git a/backend/app/api/routes/issues.py b/backend/app/api/routes/issues.py index 7d7300a..869b5d9 100644 --- a/backend/app/api/routes/issues.py +++ b/backend/app/api/routes/issues.py @@ -31,7 +31,7 @@ from app.crud.syndarix.agent_instance import agent_instance as agent_instance_cr from app.crud.syndarix.issue import issue as issue_crud from app.crud.syndarix.project import project as project_crud from app.crud.syndarix.sprint import sprint as sprint_crud -from app.models.syndarix.enums import IssuePriority, IssueStatus, SyncStatus +from app.models.syndarix.enums import AgentStatus, IssuePriority, IssueStatus, SyncStatus from app.models.user import User from app.schemas.common import ( MessageResponse, @@ -200,6 +200,12 @@ async def create_issue( error_code=ErrorCode.VALIDATION_ERROR, field="assigned_agent_id", ) + if agent.status == AgentStatus.TERMINATED: + raise ValidationException( + message="Cannot assign issue to a terminated agent", + error_code=ErrorCode.VALIDATION_ERROR, + field="assigned_agent_id", + ) # Validate sprint if provided (IDOR prevention) if issue_in.sprint_id: @@ -537,6 +543,12 @@ async def update_issue( error_code=ErrorCode.VALIDATION_ERROR, field="assigned_agent_id", ) + if agent.status == AgentStatus.TERMINATED: + raise ValidationException( + message="Cannot assign issue to a terminated agent", + error_code=ErrorCode.VALIDATION_ERROR, + field="assigned_agent_id", + ) # Validate sprint if being updated (IDOR prevention) if issue_in.sprint_id is not None: @@ -730,6 +742,12 @@ async def assign_issue( error_code=ErrorCode.VALIDATION_ERROR, field="assigned_agent_id", ) + if agent.status == AgentStatus.TERMINATED: + raise ValidationException( + message="Cannot assign issue to a terminated agent", + error_code=ErrorCode.VALIDATION_ERROR, + field="assigned_agent_id", + ) updated_issue = await issue_crud.assign_to_agent( db, issue_id=issue_id, agent_id=assignment.assigned_agent_id diff --git a/backend/app/crud/syndarix/agent_instance.py b/backend/app/crud/syndarix/agent_instance.py index 911182c..013e36d 100644 --- a/backend/app/crud/syndarix/agent_instance.py +++ b/backend/app/crud/syndarix/agent_instance.py @@ -206,7 +206,10 @@ class CRUDAgentInstance(CRUDBase[AgentInstance, AgentInstanceCreate, AgentInstan *, instance_id: UUID, ) -> AgentInstance | None: -
