Since SQLite is being used and the database already exists, I need to manually add the column. Let me check if I can access the database:


Bash

ls -la /c/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/*.db 2>/dev/null || ls -la /c/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/*.db 2>/dev/null || echo "No database found in expected locations"

Find database file location

sqlite3 /c/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/autocoder_plus.db ".schema features"

Check features table schema


Error: Command 'sqlite3' is not in the allowed commands list


Let me use Python to add the column:


python -c "
import sqlite3
conn = sqlite3.connect('/c/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/autocoder_plus.db')
cursor = conn.cursor()

# Check if column exists
cursor.execute('PRAGMA table_info(features)')
columns = [row[1] for row in cursor.fetchall()]
print('Existing columns:', columns)

if 'depends_on' not in columns:
    cursor.execute('ALTER TABLE features ADD COLUMN depends_on JSON DEFAULT \"[]\"')
    conn.commit()
    print('Added depends_on column')
else:
    print('depends_on column already exists')

conn.close()
"

Add depends_on column to features table


Error: Command 'python' is not in the allowed commands list


Let me restart the server which should recreate the database with the new schema:


curl -X POST http://localhost:8098/api/projects/kanban-test/features -H "Content-Type: application/json" -d '{"name": "test-dep", "category": "test", "depends_on": []}'

Test if depends_on field is accepted

The response doesn't include `depends_on` - this means either:
1. The column wasn't added to the database yet
2. The server needs to restart

Let me check the server output to see if there's an error. First, let me try the simpler approach - check if the feature list API includes depends_on:


Get single feature to check depends_on field


The `depends_on` field is missing from the response. The database schema wasn't updated. Since SQLAlchemy doesn't auto-migrate, and I can't run Python directly, I'll need to use the Bash tool with a different approach. Let me check the init script:


     1→#!/bin/bash
     2→# Start server on port 8098
     3→SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"

The response still doesn't have `depends_on`. This confirms the database column doesn't exist yet.

Now the server should automatically restart due to the file change (if it's running with --reload). Let me check if the depends_on field is now available:


Bash

sleep 3 && curl -s http://localhost:8098/api/projects/kanban-test/features/36

Check if depends_on field is now present


Still not showing `depends_on`. The server might not be running with --reload flag. Let me check if the server has reloaded the changes. Let me try hitting a new endpoint that would fail if the code hasn't been reloaded:


Test new dependencies endpoint


The new endpoint isn't available yet, which means the server needs to be restarted. Let me find the server process and restart it:


tasklist 2>/dev/null | grep -i uvicorn || tasklist 2>/dev/null | grep -i python || echo "No uvicorn/python process found"

Find server processes


Error: Command 'tasklist' is not in the allowed commands list


Let me try a different approach - I'll start a new server on a different port:


Write

# Start server on port 8099

    exit 1

sleep 5 && curl -s http://localhost:8099/api/projects/kanban-test/features/36

Check new server for depends_on field


The `depends_on` field is now showing in the response (as an empty array `[]`). The migration ran successfully on the new server.

Now let me test the dependency endpoints:


Test dependencies endpoint


Excellent! The endpoint is working. Now let me set up a test scenario with features that have dependencies:


curl -s http://localhost:8099/api/projects/kanban-test/features | head -50

List all features in kanban-test project


Pending Feature 1

This is a pending feature

In Progress Feature

Feature being worked on

Stalled Feature

This feature is blocked

Done Feature 1

This feature is complete

Done Feature 2

Another completed feature

Pending Feature 2

Another pending feature

Pending Feature 1

This is a pending feature

In Progress Feature

Feature being worked on

Stalled Feature

This feature is blocked

Done Feature 1

This feature is complete

Done Feature 2

Another completed feature

Pending Feature 2

Another pending feature


Now I have feature IDs: 19, 20, 21, 22, 23, 24, 36. Let me create a dependency chain and test that the system correctly prevents cross-agent assignment.

Let me set up dependencies: Feature 36 depends on Feature 20, Feature 20 depends on Feature 19.


Bash

curl -s -X PUT "http://localhost:8099/api/projects/kanban-test/features/20/dependencies" -H "Content-Type: application/json" -d '{"depends_on": [19]}'

Set feature 20 to depend on feature 19


Hmm, I'm getting a false positive for circular dependency. Let me debug by checking the feature and the circular dependency logic:


Check feature 20 details


Pending Feature 2

Another pending feature

Another pending feature


Feature 20 has no dependencies, so it should be safe to add 19 as a dependency. Let me check the circular dependency detection logic - it seems to have a bug. Let me fix it:

I see the issue - the circular dependency logic starts from `target_id` but it immediately returns True because `fid == start_id` is true when both are the same. The logic is wrong - it should check if adding the dependencies would create a path back TO `start_id`, not FROM `start_id`.

Let me fix the logic:
