Goal

B) Student + school constraints

• Current grade; completed / in-progress courses (if not starting from Grade 9)
• Special programs: French Immersion / IB / AP / etc.
• Whether the school allows: taking 12U early, cross-grade enrolment, spares in Grade 12, etc.
• Timetable constraints: typically 8 courses/year (4+4). Confirm whether 7-course years are allowed.

C) Planning priorities (must be editable)

Keep as toggles/weights:

• Workload distribution:
  • pressureFocus: "frontload" | "balanced" | "protect_11_12"
• Summer school:
  • summerSchool.enabled: true/false
  • summerSchool.maxPerYear: 1 (default)
  • summerSchool.useFor: "nonTop6" | "reachAhead" | "repeatImprove" (default: nonTop6)
• Grades/average strategy:
  • maximizeAverage: true/false
  • preferEasierElectives: true/false
• Risk tolerance:
  • planRobustness: "conservative" | "normal" | "aggressive"

Workflow (generate or update a plan)

Step 1 — Build the rule baseline (read references)

Read and apply:

• references/graduation-and-planning-rules.md
• references/summer-school-catalog.md
• references/required-bands-by-grade.md
• references/course-catalog.md

If the user provides new rules or new lists:

• Do not overwrite the files in-place during the chat.
• Clearly list what changed, and recommend writing the changes back into the appropriate references file (see “Maintenance & updates”).

Step 2 — For each target, derive prerequisites + Top 6 logic

For each (University, Program), produce:

• Likely hard prerequisites (e.g., ENG4U, MHF4U, MCV4U, SPH4U, SCH4U)
• Typical Top 6 (12U/M) composition patterns for that program

If prerequisites are uncertain:

1. Provide a conservative default for that program family (CS vs Engineering)
2. List what must be verified and provide web_search keywords/links the user can check

Step 3 — Schedule the 4-year plan

Objectives:

• Grade 9–11: satisfy “8 courses per year” rule if applicable
• Respect prerequisite chains while distributing workload
• If protect_11_12: avoid stacking multiple heavy 3U/4U courses in Grade 11/12
• If summer school is enabled and useFor=nonTop6: prioritize non-Top6 / non-admissions-impact courses (often Civics/Careers) to reduce timetable load

Planning method:

• Lock Grade 12 Top 6 candidate pool (>= 6 courses; ideally 7–8 for replacement)
• Back-plan prerequisites:
  • MHF4U/MCV4U usually require Grade 11 MCR3U
  • 4U sciences usually require corresponding 3U sciences
  • CS/Engineering interest: consider ICS/TEJ/TDJ pathways where available

Step 4 — Standardized output (required)

Output must follow this structure (do not omit sections):

1) Targets & assumptions

• Target universities/programs (multiple allowed)
• Active priorities config (pressureFocus, summerSchool, etc.)
• Key assumptions / items to confirm

2) Prerequisites + Top 6 summary (by target)

For each target:

• Prerequisite list
• Two Top 6 options (e.g., low-pressure vs high-relevance; conservative vs stretch)
• Risks and substitutes

3) 4-year course plan (by grade)

For each grade:

• Course list with: course name + code + course type (D/P/U/M/O/W/etc.) + whether it counts toward the 17 compulsory vs 13 elective credits
• End-of-year cumulative credits: total / compulsory / elective
• Rationale for that year (prereqs + workload distribution + average strategy + interests)

4) Validation checklist

• Graduation requirements met (17 compulsory, 13 elective, 2 online courses, etc.)
• Prereqs met for each target
• Grade 12 overload check (if user dislikes “overload/extra credits”, propose alternatives)

Maintenance & updates (must support)

When the user asks to modify/update anything:

1. Identify which bucket changed:

• Rules: graduation/online requirement, yearly course count, summer school limits
• Summer school: offerings, cancellations, whether a course may be used for Top 6
• Course catalog: add/remove/rename courses, codes, grade availability
• Priorities: pressureFocus, summer school on/off, risk tolerance

2. Apply minimal-change updates:

• Mark impacted grades/courses
• Provide before/after diffs
• Recalculate cumulative credits and Top 6 options

3. If the user agrees, recommend persisting updates into references:

• references/graduation-and-planning-rules.md
• references/summer-school-catalog.md
• references/course-catalog.md

Quality rules (hard)

• Never present uncertain items as facts; label them “TO VERIFY”.
• Course codes must come from references/course-catalog.md unless the user explicitly adds new ones.
• Output must include cumulative credits (total/compulsory/elective) and consistent classification.
