  1. ✓3.1 — Selecting the Right Claude Product FeatureFour ways to handle work. Match feature to the shape of the task, not habit. Ordinary chat, Projects, Research, Artifacts.Scenario: Pro
  2. ✓3.2 — Differentiating Between Claude Model TypesThree model families form a real trade-off of speed and cost against depth: Haiku, Sonnet, Opus; No tier is “the good one”. Each is the right choice for work that matches its strengths.Scenario: Pro
  3. ✓3.3 — Aligning Model Choice with Cost, Speed and QualityEvery choice between tiers spends three currencies: cost (usage allowance), time (wait per response), and depth (quality on demanding work). Name the currency a task needs, then pay only that.Scenario: Pro
  4. ✓3.4 — Managing Context Limits and Memory: Restart, Summarise, PersistA conversation holds a finite working space. When it reaches its length limit, start a new conversation or use a Project. Treat a long chat like a long meeting: know it will end, and decide what must survive it.Scenario: Pro
