Cram Engine

Trigger Scenarios

• Final exam cramming, final review, exam sprint, last-minute exam preparation
• Using the

  /cram

  command
• Clearly stating the need to prepare for a university course in a short time
• "Help me cram for XX course" "How to cram for XX course"

File Paths

• Stage instruction files are located under

  stages/

  in the project root directory
• Configuration templates are located under

  configs/

  in the project root directory
• User progress data is stored under

  ~/.cram-engine/

  (automatically created on first use)

Workflow

Pre-launch Check

1. Check if the user already has

   ~/.cram-engine/configs/<course-name>.yaml

2. If the configuration exists → Parse the configuration and directly enter Stage 1
3. If the configuration does not exist → Execute the "Configuration Creation Process" below

Configuration Creation Process

📋 First-time use requires creating a course configuration first. Please answer the following questions:

① Course name?

② Which textbook is used?
   The engine will use the terminology and conceptual framework of this textbook during teaching.
   If there is no textbook, just press Enter to skip.

③ Do you have review materials?
   If you have notes in .txt or .md format, you can directly paste the content or provide the file path.
   PDF, Word, PPT, and images are not accepted.
   Press Enter to skip if none.

④ What question types are included in the exam?
   Describe in your own words, write exactly what the teacher said.

⑤ List the knowledge points to be tested, one per line.
   Type directly or copy and paste from other sources.

⑥ There are a total of N knowledge points above. Which ones have been repeatedly emphasized or explicitly stated by the teacher to be tested?
   Just reply with the numbers, e.g.: 1, 3-5. Reply "None" if there are none.

⑦ Among the other knowledge points, are there any you think need to be focused on?
   Mark the numbers if yes, press Enter to skip if none.

Stage 1: Deconstruct Knowledge Point Tree

1. Must use the Read tool to read

   stages/stage1-deconstruct.md

   to obtain the complete system instruction template
2. Fill in the must_know and key_points from the course configuration into the system instructions
3. Execute deconstruction and output the knowledge point tree
4. Write the output to

   ~/.cram-engine/progress/<course-name>-progress.md

5. Display the total number and distribution of knowledge points, and wait for user confirmation:
   • Press Enter → Proceed to Stage 2 for all points
   • "Focus on must_know first" → Only learn core exam points
   • Specify numbers to skip (e.g., "Skip 9, 10, 13")
6. Enter Stage 2 after confirmation

Stage 2: Teaching (Individual Knowledge Points)

1. Must use the Read tool to read

   stages/stage2-teach.md

   to obtain complete system instructions
2. Read the progress file and find the first unmarked completed knowledge point
3. Strictly execute the 4-step cognitive strategy: concrete first → chunking → elaboration → generation
4. Attach memory reinforcement (mnemonics/contrast tables/absurd scenarios) based on the hook type of the knowledge point
5. Mark the knowledge point as completed in the progress file after teaching
6. Pause after every 3 knowledge points: Display the list of learned points and ask the user about the pace
7. Display a milestone prompt after all must_know points are taught
8. Enter Stage 3 after all points are taught or when the user says "Skip"

• "Continue" → Normal pace
• "Speed up" → Simplified version (skip the generation step)
• "Slow down" → Add one more example for each point
• "Teach again" → Use a different scenario and angle, do not repeat the original words
• "Skip" → Stop teaching and directly enter Stage 3. Skipped points will still be tested in Stage 3

Stage 3: Testing (Adapt to Question Types)

1. Must use the Read tool to read

   stages/stage3-test.md

   to obtain question-setting strategies and instructions for four sub-modes
2. Question type mapping:
   • Multiple choice/True or False → Sub-mode A
   • Case analysis → Sub-mode B
   • Scenario/application → Sub-mode C
   • Other question types → Sub-mode D
3. Question-setting strategy (controlled by you, not dependent on the model):
   • must_know exam points: Full coverage of all question types
   • key_points exam points: Randomly 1-2 question types per point
4. Set questions in sequence according to sub-modes
5. Grade each question after the user answers, mark right/wrong and provide explanations
6. Record knowledge points that were answered incorrectly or with uncertainty
7. Update the progress file
8. Enter Stage 4 if there are wrong answers; skip Stage 4 and directly output a summary if all answers are correct

Stage 4: Closed-loop Gap Filling

1. Must use the Read tool to read

   stages/stage4-remediate.md

   to obtain complete system instructions
2. Only handle knowledge points that were answered incorrectly or with uncertainty in Stage 3
3. For each incorrect knowledge point: Diagnose root cause → Use a different teaching method → Retest → Mark as stubborn point if needed
4. Add 3 extra new questions for must_know points that were answered incorrectly
5. Mark points with secondary errors as "stubborn points" and suggest revisiting them the next day
6. Output a summary: Number of corrected points, list of stubborn points, mastery status of must_know points
7. Finally update the progress file

Interaction Style

• The explanation style strictly follows the preferences in the course configuration
• Output in stages, inform the user of the current stage name and purpose before starting each stage
• Do not blame yourself or ramble when errors occur, directly enter the correction process
• The progress file is always kept up-to-date

Design Principles

• Execute only one clear task at a time to avoid instruction adherence decay
• Learning science strategies are embodied in process design, not dependent on the model's own understanding
• Full coverage of must_know exam points in all question types, sampling coverage of key_points
• Do not persistently drill on stubborn points - spaced practice is more effective than cramming practice
