Learn

Build a 20-hour plan to learn a topic fast, focused on the 20% that drives 80% of results. Output 10 two-hour sessions, each ending with a 15-minute review.

Step 1: Clarify the topic (if needed)

If the topic is ambiguous (e.g., "ML" → supervised? deep learning? deployment?), ask one clarifying question before proceeding. Otherwise skip.

Step 2: Research the 20%

Delegate to the researcher subagent to identify:

• The core concepts that experts agree drive most outcomes in this topic
• The best resources (books, courses, docs, videos, repos) — prefer canonical/authoritative sources
• Common beginner traps to skip

Use subagent_type: "researcher", model: "haiku".

Prompt:

text: What are the 20% of concepts in [TOPIC] that drive 80% of practical results? List the highest-signal resources (books, courses, official docs, key papers/repos) a motivated learner should use to master those concepts in ~20 hours. Flag common time-wasters to skip.
mode: deep-research

Step 3: Build the plan

Synthesize the research into 10 sessions. Each session:

• 2 hours total: ~105 min learning + ~15 min review
• One clear learning objective per session — a concrete capability, not a vague theme
• Progression: foundations → core mechanics → applied practice → integration
• Concrete resources: name the specific chapter, video, doc page, or exercise — not "read about X"
• Hands-on bias: at least half the sessions include building, coding, or solving problems
• Review block (last 15 min): recall without notes, summarize in own words, list 1-2 questions to revisit

Step 4: Present

Output format:

# 20-Hour Plan: [Topic]

**Focus:** [one-sentence framing of the 20% being targeted]
**Prerequisites:** [what learner should already know, or "none"]

---

## Session 1 — [Title] (2h)
**Objective:** [concrete capability after this session]
**Learn (105 min):**
- [Resource + specific section/chapter/exercise]
- [Resource + specific section/chapter/exercise]
**Review (15 min):**
- [Recall prompt or summary task specific to this session]

## Session 2 — [Title] (2h)
...

[continue through Session 10]

## Capstone check
After Session 10, you should be able to: [3-5 bullet outcomes]

Constraints

• Do not pad sessions with filler. If the topic genuinely fits in fewer hours, say so and propose a shorter plan instead.
• Every resource must be named specifically (title + section). No "find a tutorial on X."
• The review block is non-negotiable — it's where retention happens.
