How I automated my bug backlog with n8n and a coding agent API
Source: Dev.to
The solution
I built a workflow on top of OpenCode that processes tickets automatically:
- Trigger – a new ticket in Linear (or Jira) with a specific label fires a webhook.
- Orchestrator – n8n receives the webhook and calls the CodeCloud API.
- Execution layer – CodeCloud spins up an AI coding agent, clones the repo, implements the fix, and opens a pull request.
The n8n workflow is literally two nodes: a trigger and an HTTP request.
What works well
| Type of change | Example ticket | Result |
|---|---|---|
| Well‑described bugs | “The signup button doesn’t submit on Safari because we’re using FormData without a polyfill.” | Agent adds the polyfill and opens a PR. |
| Tedious bulk changes | “Update all error messages to use the new i18n format.” | Agent greps, updates, opens a PR. |
| Documentation | “Add JSDoc comments to all exported functions in /lib.” | Mechanical work handled automatically. |
Key insight: ticket quality determines output quality. This workflow forces the team to write better tickets, which is a side benefit even when the agent misses.
Prerequisites
- An n8n instance (cloud or self‑hosted).
- A CodeCloud account with GitHub connected.
- A Linear (or Jira) workspace.
Linear API key
Create an API key from Settings → API → Personal API keys.
CodeCloud Header Auth credential
| Name | Value |
|---|---|
| Authorization | Bearer YOUR_CODECLOUD_API_KEY |
Build the n8n workflow
Nodes
| Node | Configuration |
|---|---|
| Linear Trigger | Resource: Issue Team: Select your team |
| HTTP Request | Method: POST URL: https://codecloud.dev/api/v1/agents Authentication: Header Auth (credential above) Body (JSON): see below |
Request body (JSON)
{
"repo": "your-org/your-repo",
"prompt": "Please fix the bug or issue described in this ticket:\n{{ $json.data.title }}\n\n{{ $json.data.description }}",
"model": "claude-sonnet-4-5",
"provider": "anthropic",
"auto_create_pr": true
}
The {{ $json.data.title }} and {{ $json.data.description }} expressions pull the ticket content from Linear’s webhook payload.
Filtering tickets
Add an IF node between the trigger and the HTTP request:
Condition: {{ $json.data.labelIds }} contains YOUR_AUTO_PR_LABEL_ID
Only tickets explicitly tagged for automation will be processed.
Importable workflow JSON
You can import the following JSON directly in n8n via Workflows → Import from File:
{
"name": "Linear to CodeCloud PR",
"nodes": [
{
"parameters": {
"resource": "issue",
"teamId": "{{ YOUR_TEAM_ID }}"
},
"id": "linear-trigger",
"name": "Linear Trigger",
"type": "n8n-nodes-base.linearTrigger",
"typeVersion": 1,
"position": [240, 300]
},
{
"parameters": {
"method": "POST",
"url": "https://codecloud.dev/api/v1/agents",
"authentication": "genericCredentialType",
"genericAuthType": "httpHeaderAuth",
"sendBody": true,
"specifyBody": "json",
"jsonBody": "={\n \"repo\": \"your-org/your-repo\",\n \"prompt\": \"Please fix the bug or issue described in this ticket: \\n {{ $json.data.title }}\\n\\n{{ $json.data.description }}\",\n \"model\": \"claude-sonnet-4-5\",\n \"provider\": \"anthropic\",\n \"auto_create_pr\": true\n}"
},
"id": "http-request",
"name": "Create CodeCloud Run",
"type": "n8n-nodes-base.httpRequest",
"typeVersion": 4.2,
"position": [480, 300]
}
],
"connections": {
"Linear Trigger": {
"main": [[{ "node": "Create CodeCloud Run", "type": "main", "index": 0 }]]
}
}
}
Replace YOUR_TEAM_ID and your-org/your-repo, then attach the Header Auth credential you created earlier.
Using Jira instead of Linear
Replace the Linear Trigger with a Jira Trigger (event: issue_created). Adjust the request body to match Jira’s payload:
{
"repo": "your-org/your-repo",
"prompt": "{{ $json.issue.fields.summary }}\n\n{{ $json.issue.fields.description }}",
"model": "claude-sonnet-4-5",
"auto_create_pr": true
}
Useful API parameters
| Parameter | Description |
|---|---|
mode: "plan" | Returns an implementation plan without making changes—good for review before execution. |
webhook_url | URL to be notified when the run finishes; can be used to post the PR link back to Slack or update the ticket status. |
Tips & considerations
- The workflow may produce imperfect PRs; treat them as drafts that a developer can quickly polish.
- Failed attempts often surface ambiguous ticket details or edge cases, prompting better documentation.
- Start by creating an auto‑PR label in Linear, tag a few well‑described bugs, activate the workflow, and observe the results.
