⚡ Slash Commands

Slash commands provide command-based interactions with DAIV directly from issues and merge/pull requests. They are useful for common tasks and information requests.

Slash commands vs. direct mentions

DAIV responds to two types of interactions:

Interaction Type Format Use Case
Slash Commands @daiv /command Execute specific commands (get help, clone issues)
Direct Mentions @daiv <request> Address code review comments, ask questions, request code changes

To address code review comments, use a direct mention without a slash command. See Review Addressor for details and examples.

Overview

Slash commands are triggered by mentioning DAIV with specific commands in issue or merge/pull request comments.

How slash commands work

Command Format: @<daiv-username> /<command> [arguments]

Supported Scopes:

  • Issues: Available in issue comments and discussions
  • Merge/Pull Requests: Available in merge/pull request comments and discussions

Command Parsing:

Slash commands use shell-like parsing with support for:

  • Simple commands: @daiv /help
  • Commands with arguments: @daiv /clone-to-topic backend, api
  • Case-insensitive: @DAIV /HELP works the same as @daiv /help

Available slash commands

🆘 Help command

Command: /help

Purpose: Displays all available slash commands for the current scope (issue or merge/pull request).

Scopes: Issues, Merge/Pull Requests

Example:

Text Only
1
@daiv /help

Response: DAIV replies with a formatted list of all available slash commands and their descriptions.

🧹 Clear command

Command: /clear

Purpose: Clear the conversation context and start a fresh conversation with DAIV.

Scopes: Issues, Merge/Pull Requests

Usage: When you want to reset the conversation history and start fresh, use this command. This deletes the thread associated with the current issue or merge request, effectively clearing DAIV's memory of the conversation.

Example:

Text Only
1
@daiv /clear

Response: DAIV replies with a confirmation that the context has been cleared successfully.

Behavior:

  • Deletes the conversation thread for the current issue or merge request
  • Clears all conversation history and context
  • Allows starting a new conversation from scratch
  • Useful when previous context is no longer relevant or causing confusion

📤 Clone to topic command

Command: /clone-to-topic <topics>

Purpose: Clone the current issue to all repositories matching the specified topics.

Scopes: Issues only

Arguments: Comma-separated list of topics to match repositories against.

Usage: Leave a comment specifying the topics, and DAIV will create a copy of the issue in every matching repository (excluding the current one).

Example:

Text Only
1
@daiv /clone-to-topic backend, microservices

Response: DAIV replies with a summary of the cloned issues, including links to each new issue created.

Behavior:

  • Searches for repositories that have all the specified topics
  • Excludes the current repository from the target list
  • Copies the issue title, description, and labels to each target repository
  • Reports how many issues were successfully created and lists them

Troubleshooting

Common issues

Command not recognized:

  • Check that the command supports the current scope (issue vs merge/pull request)
  • Ensure proper spelling and case (commands are case-insensitive)
  • Verify command syntax (e.g., /help not /Help)

No response from DAIV:

  • Confirm DAIV has access to the repository
  • Check that webhooks are properly configured
  • Verify the bot username is correct in the mention

Permission errors:

  • Ensure DAIV has sufficient repository permissions
  • Confirm the user triggering the command has appropriate access levels

Pipeline command issues:

  • Ensure the pipeline is in "failed" status
  • Check that failed jobs have script_failure as the failure reason
  • Verify jobs are not marked as allow_failure

Clone to topic command issues:

  • Ensure you provide at least one topic
  • Check that target repositories have the specified topics configured
  • Verify DAIV has access to the target repositories
  • Confirm the current repository is not the only one matching the topics

Debug information

Slash commands log detailed information for troubleshooting:

  • Command parsing results
  • Registry lookup attempts
  • Execution success/failure
  • Error details and stack traces

Extension and development

Adding new commands

  1. Create new command class in slash_commands/actions/
  2. Implement required methods execute_action_for_issue, execute_action_for_merge_request, and execute_for_agent
  3. Decorate with @slash_command specifying command and scopes
  4. Import in the actions module
  5. Test the command in development environment

Best practices

  • Keep commands simple: Slash commands should execute immediately
  • Provide clear descriptions: Help users understand what each command does
  • Handle errors gracefully: Post user-friendly error messages
  • Use appropriate scopes: Only enable commands where they make sense
  • Follow naming conventions: Use clear, descriptive command names
