[Scenario: Code Generation with Claude Code] You need to add Slack as a new notification channel. The existing codebase has clear, established patterns for email, SMS, and push channels. However, Slack’s API offers fundamentally different integration approaches—incoming webhooks (simple, one-way), bot tokens (support delivery confirmation and programmatic control), or Slack Apps (two-way events, requires workspace approval). Your task says “add Slack support” without specifying integration method or requiring advanced features like delivery tracking. How should you approach this task?

• A.Start in direct execution mode using incoming webhooks to match the existing one-way notification pattern.
• B.Switch to planning mode to explore integration options and architectural implications, then present a recommendation before implementation.
• C.Start in direct execution mode by scaffolding a Slack channel class using existing patterns, deferring the integration method decision.
• D.Start in direct execution mode using a bot-token approach to ensure delivery confirmation is possible.

Show answer & explanations

Correct answer: B

A: Webhooks match the current one-way channels, but the task never chose that method, and the other Slack options change the design. Executing first locks in the guess.

B: Slack integration has multiple valid approaches with significantly different architectural implications, and requirements are ambiguous. Planning mode lets you evaluate trade-offs among webhooks, bot tokens, and Slack Apps and align on an approach before implementation.

C: Scaffolding a class before choosing webhooks, a bot token, or a Slack App builds the wrong shape if the method changes.

D: Bot tokens add delivery confirmation the task did not ask for, and they are a heavier path than the channels that exist today.
