List the direct course routes exposed on the Ninova course home page.

Read the Ninova 'Notlar' page for a course — grades as the instructor entered them in the LMS, not the official transcript record. For the official letter/midterm grade, use obs_get_course_grades instead.

Read the Ninova 'Mesaj Panosu' page for a course.

Read the Ninova 'Yoklama' page for a course — attendance as the instructor recorded it in the LMS, not the official OBS record. For official attendance with an absence-risk summary, use obs_get_attendance instead.

List the student's OBS academic programs (e.g. undergraduate major).

List academic semesters available in OBS for the student.

Read official OBS registration status, class/GPA provenance and published class registration windows. Personal holds and credit limits are reported only when verified.

Read the saved OBS registration draft with CRNs, course names, saved eligibility verdicts, restriction reasons, last check time and available draft meeting times. Reads the active registration term. Does not save or recheck the draft. Saved eligibility is a snapshot; use obs_validate_registration_plan for a fresh check.

Replace the saved OBS registration draft with exactly one to twelve supplied CRNs. This changes the user's saved draft and can replace its existing contents. Requires the user's explicit confirmation of the exact CRNs and replacement, confirm=true, and the operator's NINOVA_OBS_REGISTRATION_WRITES=1 opt-in. Does not register or drop courses. If the save would remove courses already in the draft, nothing is sent and the result lists previous_crns and removed_crns; call again with allow_replace=true only after the user accepts losing them. Reports saved, unchanged, rejected or uncertain based on the submission and fresh draft readback. An uncertain result is not proof that the draft was saved. Local stdio only.

Read any official elective group by group_id, including eligible course membership, current undergraduate offerings, CRNs, meeting times and student-specific section eligibility. Each section is checked independently, up to 8 sections per call. Membership and schedules are public; eligibility requires an OBS session. Unknown source data stays unknown. Does not change the saved draft or registration.

Validate one to twelve proposed CRNs using the independent OBS CRN checker, public meeting times, official prerequisite rules and the student's completed course history. Reports time conflicts, program/credit/class restrictions, possible elective-slot assignments, remaining graduation requirements and prerequisite-chain deferral risks. Planned courses count toward future chains only conditionally on passing, never as already completed prerequisites. Returns valid, invalid or incomplete. Future course offerings and final graduation are not guaranteed. Does not save a draft or register courses.

Read public OBS historical letter-grade counts and percentages for a course, by term. year is the academic ending year: 2026 means 2025-2026; defaults to the current calendar year. Optionally select a term_code returned in available_terms. Reports AA, BA, BB and every other published grade, including plus grades. OBS may combine Turkish and English course codes; reported_course_codes states the actual aggregate scope. No login required.

Read academic advisor information from OBS.

Read internship records from OBS.

Read contact records from OBS (phones/emails redacted by default).

List courses registered in OBS for a semester (default: latest).

Read the official midterm and/or letter grades for an OBS class (by sinifId or course code) — the authoritative record. For grades as entered in the Ninova LMS by the instructor, which can differ before the official record is updated, use get_course_grades instead.

Read the official attendance record for an OBS class, with a computed absence-risk summary by default. For attendance as recorded in the Ninova LMS by the instructor, use get_course_attendance instead.

Read weekly class schedule and final exam calendar for a semester.

Read 'mezuniyetime ne kaldı', academic status, and debts for a program. The 'summary' field maps each filled elective slot to the real course that satisfies it (e.g. BLG 422E → '7th Sems. Elect. Course I (MT)'), lists open slots and remaining required courses, and tallies credits. Read 'summary' first; the raw 'graduation' payload is the unreduced source.

Read campus card balance and recent transactions from OBS (requires login).

Download OBS transcript preview PDF to the local state downloads folder.

Look up exact course codes in public OBS; name or partial-code searches use the labeled course archive. Results do not establish current-term offerings. No login required.

Public, no login required. Query prerequisite and postrequisite relationships for a course from the OBS public catalog. Supports chain queries up to 10 levels deep.

Calculate a term GPA estimate from OBS registered courses and compare it with the official term record. For factual average questions use preferred_term_gpa and preferred_term_gpa_source; the legacy gpa field remains the calculated estimate. This is a term average, not cumulative GANO. Supports projected grades for what-if scenarios. Uses İTÜ 4.00-scale letter grade conversion.

Estimate the future average required to reach a target cumulative GPA without reading a transcript.

Estimate a likely letter grade from raw class scores under İTÜ's relative-grading (bağıl değerlendirme) rules, using both official methods: Method 1 (T-score against Table 1, an EXAMPLE class-level table from the regulation — the actual instructor may use different T-score cutoffs) and Method 2 (mean ± standard-deviation multiples, Table 2, a fixed formula with no table lookup). This is an estimate for planning purposes only, not the official grade. class_scores must be every student's raw 0-100 score who counts toward the relative-grading average (VF students are excluded from that average per the regulation and must not be included here).

Check for schedule time conflicts between courses by CRN. Uses the public course schedule to look up session day/time/room.

Read an official semester-by-semester OBS curriculum; latest plan is selected by default.

Explain whether a course's prerequisites are satisfied, using the official OBS branch prerequisite table (full Ve/Veya expression, per-course minimum grades, and credit requirement). Supports 3- and 4-digit codes including capstone courses like CEN 4901E. 'prerequisite_status' distinguishes 'no_prerequisites' (proven absent from the official table) from 'unknown' (table unreadable) — never read an empty result as 'no prerequisites'. 'cross_check' additionally diffs the result against an independent community dataset (third-party, not official); OBS stays authoritative and a disagreement is reported, never silently resolved either way. 'archive_seasonality', when the archive has the course, flags courses that only open in one term of the year (e.g. eligible now, but only ever offered in Güz) — check it even when eligibility alone looks fine.

List every term held in the İTÜ ders arşivi (2016-2017 onward), including terms OBS no longer publishes and terms not yet active. Use this to find valid term slugs like '2025-2026-guz' for the other archive tools.

Term-by-term offering history for a course from the archive: which terms it ran, how many sections, which instructors, and which season it opens in. Answers 'is this course ever offered in the spring?', which OBS cannot.

List every instructor who has taught a course across archived terms, ranked by how many terms they taught it, with their most recent term and average section fill rate.

List the courses one instructor has taught across archived terms, newest first. Returns candidate matches when the name is ambiguous.

List archived sections for a term, filtered by branch, course code, or instructor. Critically, the archive holds terms OBS has not published yet, so upcoming-term offerings can be checked instead of guessed.

How full a section got. With a CRN, reads that term's quota time series. With a course code, reports capacity vs enrolment across every past section so you can judge whether the course reliably fills up.

Search the archive's full course index by code or name fragment, across every term it has ever seen — not just the active one. Use this to find the exact code archive_course_history needs when only a name fragment is known.

List every branch present in one term's archive dump, with section and course counts. Answers 'does this branch even have a döküm for this term?' directly, instead of probing archive_term_sections branch by branch.

Diff one course's sections between two archived terms: instructor turnover, section-count delta, and capacity/fill movement, named explicitly rather than left for two separate archive_term_sections calls to be compared by eye.

Combine obs_get_graduation_remaining's remaining required courses with archive seasonality and who_taught history for each, producing a one-line scheduling recommendation per course (e.g. 'only offered in Güz, usually taught by X, average fill 0.95 — plan for Güz'). Replaces manually calling archive_course_history once per remaining course.

Letter grade counts for a course across the terms the archive has (from 2023-2024 on): per term the counts, published total, percentages, and the OBS source URL. Only the exact code is used; a Turkish/English sibling such as 'BLG 212' vs 'BLG 212E' is listed under 'related_codes', never merged, and 'same_counts_as' marks terms where the archive stores identical numbers under both codes (do not add them up). Grade labels are passed through as published, including the '+' grades; a label absent from a term was not published and is not zero. 'total_mismatch' flags terms where the published total differs from the sum of the counts; both numbers are kept. Check 'coverage': 'branch_grades_missing' means no grades file was ever recorded for the branch.

Catalog entry for a course from the archive: Turkish and English name, language, credits (theory/practice/lab/local/ECTS), description, learning outcomes, weekly topics, textbooks, and the OBS source URL. Fields the catalog does not hold are named in 'missing_fields' rather than filled in. 'coverage' separates 'course_absent_from_catalog' from 'branch_catalog_missing' (no catalog file was ever recorded for the branch).

Which courses list the given course as a prerequisite, from the archive's reverse prerequisite index. This is the direct next level only, not the whole chain. Prerequisite rules have AND/OR alternatives and minimum grades that this flat list does not express, so passing the course does not by itself make the listed courses takeable: call explain_course_eligibility on a listed course for the real rule. 'coverage' is 'not_listed_as_prerequisite' when no course names it.

Search one whole term across all branches at once by course code fragment, course name fragment, instructor, and/or day; every filter given must match. Matching is case-insensitive and Turkish-aware ('sahin' finds 'Şahin'). Defaults to the archive's current term. Use this when the branch is unknown or the question spans branches; archive_term_sections reads a single branch in more detail. Returns 'match_count' and 'truncated' alongside 'coverage'.

Final exam schedule the archive recorded for a term (date, day, time, place, exam type), optionally filtered by branch or exact course code. Most terms have no recorded schedule: 'coverage' is then 'exam_schedule_not_recorded', which means the schedule was never captured, not that there are no exams. For the live current schedule use get_public_exam_schedule.

When the archive scraper last ran and last succeeded, its section count, whether the last run was partial, which branches failed, and the data age in days. Informational only: the archive deliberately stops scraping outside registration and add/drop weeks, so an old date is expected and is not an error.

Add course sections to a local seat watch list by CRN, so a later check_watched_course_sections call can report when a full section opens. Needs no login. With 'department_code' the CRNs are looked up in that department's public OBS schedule. Without it the branch is found from the course archive's current-term search index, then confirmed against the live schedule; this only works while the archive's current term is the term OBS is serving. At most 20 sections can be watched. The entry stores the term, because CRNs are reused across terms. This does not start any monitoring: the server cannot run in the background and never notifies anyone. Seats are read only when check_watched_course_sections is called.

Remove sections from the local seat watch list. Give exactly one of: 'crns' (those sections), 'stale_only' (every entry from a term other than the one OBS is serving now), or 'clear_all' (the whole list). Only the local list changes; nothing is sent to OBS apart from reading the active term for 'stale_only'.

List the sections on the local seat watch list with the term each was added in and the last stored observation. Reads only local state, not OBS, so the numbers are as old as the last check_watched_course_sections call.

Read the public OBS schedule now for the watched sections (one request per branch, no login) and report per section: capacity, enrolled, seats free, and what changed since the previous check ('opened', 'filled', 'capacity_raised', 'delisted', ...). The first check of a section only sets a baseline. Status 'unknown' means OBS gave no usable numbers (missing values, or the enrolled column not populated yet) and is never a free seat; 'not_listed' means the CRN is absent from the schedule, which is not the same as full. Entries from a past term are reported as 'stale_term' and not compared. This is a one-shot check: the server cannot run in the background and sends no notifications, so a periodic check must be driven by the user or by a scheduled task on the client. Schedule reads are cached for a short time; when 'freshness.all_from_cache' is true the numbers were not re-read, so wait 'retry_after_seconds' instead of calling again in a loop.

Build an iCalendar (.ics) document from the weekly meetings of the given CRNs, read from the public OBS course schedule (no login). Each meeting becomes a weekly recurring event in Europe/Istanbul time between the first and last day of classes. Those two dates are taken from term_start/term_end; when omitted the academic calendar page is checked, but it covers only the displayed month, so the result is often status='term_dates_required' with no calendar: ask the user for the dates instead of guessing. Meetings whose day or time is a placeholder ('-', '--') are listed in 'skipped' and never given a time; CRNs not found in the scanned departments are in 'missing_crns'. Holidays are not excluded from the recurrence. Returns the text in 'ics'; it does not write a file.

Build an iCalendar (.ics) document from the current public OBS final exam schedule (no login), filtered to the given course codes. Each exam is a single dated event in Europe/Istanbul time. An exam whose date or time is missing or unreadable is listed in 'skipped'; a code with no row is in 'not_found'; a branch whose schedule is not published yet is skipped with 'exam_schedule_not_published', which is not the same as having no exam. When only a start time is published the event has no end time ('end_time_unknown'). Returns the text in 'ics'; it does not write a file.
