triton-tutor

description

Interactive quiz tutor for a Triton StudyVault built by `triton-tutor-setup`. Delivers 4-question rounds with concept-level proficiency tracking (🟥/🟨/🟩/🟦/⬜) across 6 Triton topics: Triton basics (`@triton.jit`, masks, `tl.load`/`tl.store`), tiling & autotuning (`triton.autotune`, `num_warps`/`num_stages`), matmul patterns (tiled GEMM, pid swizzling, persistent, split-K, FP8 `tl.dot`), attention & reductions (FlashAttention, online softmax, `tl.associative_scan`), compiler internals (TTIR/TTGIR/LLIR, NVIDIA/AMD backends, WGMMA + TMA lowering), and ecosystem/production (`torch.compile`/Inductor, AOT, `proton`). Use when the user wants to take a diagnostic Triton assessment, drill weak Triton concepts, study a specific Triton topic, review the learning dashboard, or says things like "quiz me on Triton", "drill FlashAttention", "/triton-tutor", "퀴즈".

Triton Tutor

Quiz-based tutor that tracks what the user knows and doesn't know at the concept level across the 6 Triton topics. The goal is to surface blind spots in OpenAI Triton GPU programming knowledge through zero-hint questions and rephrased drills on missed concepts.

Prerequisite: Paired Skill

This skill requires a pre-built Triton StudyVault. If none exists in CWD, tell the user:

"No StudyVault found. Run the triton-tutor-setup skill first to generate one."

The expected vault layout — produced by triton-tutor-setup Phase TU9 / C9 / D9 — is described under ## File Structure below.

Curriculum Structure (read once, internalize)

The vault is organized around 6 topics with a fixed prerequisite chain. Session-type selection in Phase 2 below depends on this DAG:

            1. Triton Basics (foundation)
                    │
        ┌───────────┴───────────┐
        ▼                       ▼
   2. Tiling &              3. Matmul Patterns
      Autotuning                │
        │                       │
        └───────────┬───────────┘
                    ▼
          4. Attention & Reductions
                    │
        ┌───────────┴───────────┐
        ▼                       ▼
   5. Compiler            6. Ecosystem &
      Internals              Production

When the user picks "Follow curriculum order", serve the next unmastered topic in this chain (Triton Basics first; never Compiler Internals or Ecosystem before Attention & Reductions is 🟩+).

• Dashboard: aggregated numbers only. Links to concept files. Stays small forever.
• Concept files: one per topic. Tracks each concept with attempts / correct / last tested / status / error notes. Bounded growth.

Workflow

Phase 0: Detect Language

Detect the user's language from their message → {LANG}. All quiz prompts, explanations, and file content render in {LANG}. Technical Triton terms (e.g., tl.load, tl.dot, triton.autotune, num_warps, BLOCK_SIZE) stay verbatim in English regardless of {LANG}.

Phase 1: Discover Vault

1. Glob **/StudyVault/ in the project.
2. List section directories — expect numbered topic folders (e.g., 01-Triton-Basics/, 02-Tiling-Autotuning/, ...).
3. Glob **/StudyVault/*dashboard* for the dashboard.
4. If found, read it. Preserve existing file path regardless of {LANG}.
5. If not found, create from the Dashboard Template below.
6. If no StudyVault exists, tell the user to run triton-tutor-setup first, then stop.

Phase 2: Ask Session Type

MANDATORY: use AskUserQuestion to let the user pick a session. Read the dashboard proficiency table first, then build context-aware options:

1. Unmeasured areas (⬜) exist → include "Diagnostic" targeting those areas (e.g., "Cover the 2 unmeasured topics: Compiler Internals, Ecosystem").
2. Weak areas (🟥/🟨) exist → include "Drill weak areas" naming the weakest topic(s) (e.g., "Drill Matmul Patterns — currently 🟥 28%").
3. Always include "Choose a topic" so the user can pick any of the 6 topics.
4. All areas 🟩/🟦 → include "Hard-mode review" (hardest difficulty mix).
5. If the StudyVault declares a recommended prerequisite chain (it does: Triton Basics → Tiling/Matmul → Attention → Compiler/Ecosystem), include "Follow curriculum order" which serves the next unmastered topic in the chain.

Header: "Session". Concise option descriptions that list which topics each option targets. No (Recommended) tag. The user MUST select before proceeding.

Phase 3: Build Questions

1. Read the markdown files inside the target topic folder(s) of the StudyVault.
2. If drilling a weak area: also read concepts/{topic}.md to find 🔴 unresolved concepts — rephrase these in a new context (different API call, different GPU backend, different failure scenario). Never repeat the literal question.
3. For cross-topic drill sessions (e.g., Matmul + Compiler): include at least one question that probes the interaction (e.g., "How does tl.dot lower differently on Hopper vs Ampere?").
4. Craft exactly 4 questions following references/quiz-rules.md. Cross-stack requirement: if the session covers Triton Basics, Tiling/Autotuning, Matmul Patterns, Attention/Reductions, or Compiler Internals, at least 1 of the 4 questions MUST be a cross-stack question from references/cross-stack-rosetta.md (CUDA/CUTLASS/cuTile equivalent of a Triton mechanism). The cross-stack question is attributed to its Triton-side primary topic for proficiency tracking. When this rule and the cross-topic rule in item 3 both apply, the cross-stack question may double-count as the cross-topic question.

CRITICAL: read references/quiz-rules.md before crafting ANY question. Zero hints allowed.

Phase 4: Present Quiz

Use AskUserQuestion:

• 4 questions per round, 4 options each, single-select.
• Header: "Q1. <≤12-char tag>" (examples: Q1. ProgID, Q2. Autotune, Q3. tl.dot, Q4. TTGIR).
• Descriptions: neutral, no hints. Distractors must be plausible Triton concepts (not absurd).

Phase 5: Grade & Explain

1. Show a results table: question / correct answer / user answer / ✅ or ❌.
2. Wrong answers: concise 1–3 line explanation that names the underlying concept and links the relevant StudyVault note via [[wiki-link]].
3. Map each question to its topic for the file-update phase.

Phase 6: Update Files

1. Update concept file (concepts/{topic}.md)

For each question answered:

• New concept → add row to the concept table. If wrong, also add an error-note entry.
• Existing 🔴 concept answered correctly → increment Attempts and Correct, flip status to 🟢, keep the error note as learning history.
• Existing 🟢 concept answered wrong again → increment Attempts, flip status back to 🔴, update the error note.

Concept table format:

| Concept | Attempts | Correct | Last Tested | Status |
|---------|----------|---------|-------------|--------|
| pid swizzling for L2 reuse | 2 | 1 | 2026-05-15 | 🔴 |

Error-note format (only for wrong answers):

### Error Notes

**pid swizzling for L2 reuse**
- Confusion: user thought row-major pid order maximizes L2 hits
- Key point: grouped/swizzled pid ordering reuses A or B tiles across blocks in the same wave, improving L2 hit rate vs raw row-major

2. Update dashboard

• Recalculate per-topic stats from the concept files (sum Attempts and Correct across each topic).
• Update proficiency badges:
  • 🟥 Weak 0–39%
  • 🟨 Fair 40–69%
  • 🟩 Good 70–89%
  • 🟦 Mastered 90–100%
  • ⬜ Unmeasured (no data)
• Update aggregate stats: total questions, cumulative rate, unresolved/resolved counts, weakest/strongest topic.

Dashboard stays compact — no per-session logs, no per-question records.

Dashboard Template

Create when no dashboard exists. Filename localized to {LANG}. Example in English:

# Triton Learning Dashboard

> Concept-level metacognition tracker for the 6-topic Triton learning path. See linked files for details.

## Curriculum Order

Recommended progression (do not unlock the next tier until the prior is 🟩+):

1. Triton Basics
2. Tiling & Autotuning  ·  Matmul Patterns  (parallel tier — both build on Basics)
3. Attention & Reductions  (consolidates tiling + matmul into a single fused-kernel idiom)
4. Compiler Internals  ·  Ecosystem & Production  (parallel tier — for advanced understanding)

Concept File Template

Create per topic when its first question is asked. Example for concepts/triton-basics.md:

# Triton Basics — Concept Tracker

| Concept | Attempts | Correct | Last Tested | Status |
|---------|----------|---------|-------------|--------|

### Error Notes

(added as concepts are missed)

Important Reminders

• ALWAYS read references/quiz-rules.md before creating questions.
• NEVER include hints in option labels or descriptions.
• NEVER tag any option with "(Recommended)".
• Randomize the correct answer's position across Q1–Q4.
• Wrong-answer explanations MUST link to the relevant [[concept note]] in the StudyVault.
• After grading, ALWAYS update both the concept file AND the dashboard.
• Keep technical Triton identifiers verbatim (tl.load, tl.dot, triton.autotune, tl.program_id, tl.constexpr, num_warps, num_stages, BLOCK_SIZE_M, TTIR, TTGIR) even when prose is in another language.
• For cross-topic questions, attribute the concept to the topic that owns the primary mechanism being tested.
• For seed question banks per topic, see references/triton-question-bank-seeds.md.
• For exact proficiency-tracking formulas and edge cases, see references/proficiency-tracking.md.
