GitLab

This guide covers setting up a Qwen Code channel that monitors GitLab todos and responds to mentions on issues and merge requests.

Prerequisites

• A GitLab account (or a dedicated bot account)
• A GitLab Personal Access Token with read_api and api scopes

Creating a Token

1. Go to Preferences → Access Tokens
2. Create a token with these scopes:
   • read_api — read todos and project data
   • api — post notes (comments) on issues/MRs
3. Save the token securely as an environment variable

Configuration

Add the channel to ~/.qwen/settings.json:

{
  "channels": {
    "my-gitlab": {
      "type": "gitlab",
      "token": "$GITLAB_TOKEN",
      "pollInterval": 60000,
      "senderPolicy": "open",
      "sessionScope": "chat_thread",
      "cwd": "/path/to/your/project",
      "groupPolicy": "open",
      "action_prompt_template": {
        "mentioned": "Project: %project% | URL: %project_url% | Author: %author% | Type: %target_type% | IID: %iid% | Title: %title% | Description: %description% | TodoID: %todo_id%"
      }
    }
  }
}

Set the token as an environment variable:

export GITLAB_TOKEN="glpat-your_token_here"

Self-hosted GitLab

For self-hosted instances, set baseUrl:

{
  "baseUrl": "https://gitlab.example.com"
}

Configuration Options

Option	Default	Description
token	(required)	PAT with read_api + api scopes
pollInterval	60000	Poll interval in ms
baseUrl	https://gitlab.com	GitLab instance URL
action_prompt_template	(required for processing)	Maps GitLab action names to metadata templates
groupPolicy	"disabled"	Must be "open", or "allowlist" with the project listed
senderPolicy	"allowlist"	Who can trigger the bot

action_prompt_template

This field controls which todo actions are processed and how metadata is rendered. Only actions with a configured template are dispatched; all others are skipped and marked done.

{
  "action_prompt_template": {
    "mentioned": "Project: %project% | Author: %author% | Title: %title%"
  }
}

The directly_addressed action (comment starting with @bot) automatically falls back to the mentioned template if not explicitly configured.

Available Action Keys

Key	Trigger
mentioned	Someone @mentions the bot in a comment or description (not at the start)
directly_addressed	A comment starts with @bot (falls back to mentioned template)
assigned	Someone assigns the bot to an issue/MR
review_requested	Someone requests the bot as a reviewer on an MR
approval_required	An MR requires the bot's approval (approval rules)
marked	Someone marks the bot's comment/issue/MR (star)
build_failed	A CI/CD pipeline fails on the bot's branch/MR
unmergeable	An MR the bot is involved with becomes unmergeable (conflicts)
merge_train_removed	An MR is removed from the merge train

Only keys present in action_prompt_template are processed. Unconfigured actions are skipped and marked done silently.

Template Variables

Variable	Value
%project%	Project path (e.g., owner/repo)
%project_url%	Full project URL
%author%	Todo author username
%target_type%	Issue or MergeRequest
%iid%	Issue/MR internal ID
%title%	Issue/MR title
%description%	Issue/MR description body
%todo_id%	GitLab todo ID
%%	Literal % (escape)

Unknown variables are preserved as-is in the output.

Prompt Assembly

The template renders into envelope.metadata (structured context). The triggering text (todo.body or description) goes into envelope.text (primary prompt). The base class assembles the final prompt sent to the agent:

[alice] please fix this bug

Project: owner/repo | URL: https://gitlab.com/owner/repo | Author: alice | Type: Issue | IID: 42 | Title: Test Issue | Description: ... | TodoID: 100

• Line 1: [sender] prefix + envelope.text (with @bot stripped)
• Line 3: envelope.metadata (rendered template, sanitized)

You do not need a %body% variable — the comment/description text is always the primary prompt content, and the template provides supplementary context below it.

⚠️ Security

On a public project, setting senderPolicy: "open" allows any GitLab user who @mentions the bot to submit prompts that drive the agent in your cwd.

Always use senderPolicy: "allowlist" with explicit allowedUsers on public projects.

Mention Detection

The adapter always sets isMentioned = true on dispatched envelopes, because GitLab has already determined the mention when creating the todo. The action_prompt_template config is the real event filter — only actions with a configured template are processed. The @bot mention is stripped from the message text before dispatch via stripBotMention.

⚠️ groupPolicy Must Be "open" or "allowlist"

groupPolicy must be set to "open", or "allowlist" with the project explicitly listed, for todos to be processed. The default value "disabled" drops all mentions: todos are marked done and the cursor advances, but no dispatch occurs. A rejection is logged (preflight rejected reason=group_disabled) but the todo is still consumed. If your bot is not responding to mentions, check that groupPolicy is not "disabled".

How It Works

The adapter uses GitLab's Todos API as the message source:

1. Poll GET /todos?state=pending for new todos
2. First-poll drain: if the cursor has never been initialized (initialized: false), all pending todos are marked done without dispatch and the cursor advances to the max todo ID. This prevents a backlog flood on first start.
3. Clean up stale todos: todos with id <= cursor are marked done (best-effort) to prevent them from being re-fetched on every poll
4. Filter by id > cursor and configured action_prompt_template
5. Detect mention type via target_url anchor:
   • #note_123 present → comment mention → text is todo.body (the comment)
   • No anchor → description mention → text is the issue/MR description
6. Dispatch the envelope through handleInbound (requires groupPolicy: "open" or "allowlist" with the project listed)
7. Advance cursor and mark todo done (best-effort)

The cursor (lastProcessedId) advances regardless of dispatch success or failure. Failed dispatches post a ⚠️ error comment on the issue/MR and are not retried — the user can re-mention the bot to trigger a new todo.

Known Limitations

• First start skips existing pending todos. The cursor initializes to { lastProcessedId: 0, initialized: false } on first launch. On the first poll cycle, all pre-existing pending todos are marked done without dispatch (the initialized flag gates this one-time drain), preventing a backlog flood.
• The bot does not read prior conversation history — only the triggering content is processed.
• Confidential (internal) notes: If someone @mentions the bot in a confidential note, the todo body contains that internal text and the agent will process it. The bot's reply is always posted as a public note, potentially exposing internal discussion. GitLab's todo API does not expose note visibility, so the adapter cannot filter this. Avoid @mentioning the bot in confidential notes.
• Requires read_api + api PAT scopes. Group-level or project-level tokens work if they have these scopes.
• Todos for Epics, Designs, and Alerts are skipped (only Issues and MRs are processed).
