Check the UNW session: authenticated (live check), degraded (state exists but the live check failed), state-file age, cookie count and earliest cookie expiry (values are never exposed), plus read_hint/write_hint and the exact packaged CLI command that repairs an expired session. Call this before any other tool. If unauthenticated but degraded, try one read tool before asking for a login.

Student profile from Degree Works: name, id, classification, degree/school, catalog year(s), majors, minors, programs, college, advisors, credits earned and in progress, GPA, percent complete, anticipated graduation, academic standing and holds. Holds are not exposed by the mapped APIs: null = unknown.

Structured degree-audit requirement tree (groups -> blocks -> course options, with applied/in-progress/transfer flags). group filters by a case-insensitive substring of a group title/kind or block label.

Unmet requirements only: id, title, parent group, kind, credits remaining, pick-N progress, course/attribute/wildcard options, status, priority class and shared_title_with (other ids with the same title/options: double-counting risk). This is the authoritative "what is left" list.

Banner term codes with descriptions plus is_next, is_current, view_only and registration_eligible flags. Eligibility is probed through Banner's own mode=registration response (cached per process); refresh=True re-probes it. Failures are included verbatim.

Search one term's sections (normalised rows: CRN, course, title, credits, seats, days/times, faculty, attributes, availability). Banner ignores the attribute/instructor/open-only query parameters, so filtering happens client-side over a cached term snapshot. limit is capped at 200; when limit_capped is true follow next_offset to page through the rest.

Full detail for one CRN: meetings, faculty with RMP evidence, attributes, catalog description, prerequisite/corequisite/restriction text plus the parsed prerequisite codes, linked lecture/lab CRNs, enrollment text and availability.

Resolve unmet requirements to sections offered in term (wraps the catalog resolver). requirement matches an id, title, parent group or target; omit it for every unmet requirement. Every empty result carries the reason (never offered / all closed / already completed). limit caps candidates per requirement (0=all); compact omits repeated section detail. One requirement can be large, so prefer compact/limit for broad queries.

Batch Rate My Professors lookup. Accepts "Last, First" or "First Last". Unrated professors return rating=null (never 0.0); weak_evidence flags n<3. Cache entries expire after 7 days; refresh=True refetches now. Transient RMP failures are never cached.

Pairwise time conflicts for a CRN set, plus the ASCII week grid and the list of unscheduled (TBA/asynchronous) sections. Half-open intervals; linked lecture/lab pairs are exempt.

Draft a conflict-free term plan from the audit, prioritizing major-required courses, then major pools, then gen-ed by RMP rating.

required_crns/required_courses pin sections the student insists on; each pin reports placed/unavailable/conflict/prereq_blocked/excluded/budget and a failed pin makes ok=false. exclude_crns/exclude_courses remove candidates. min_credits keeps filling elective pools until the load is met (and reports min_credits_met). hours maps a CRN to the credit hours to reserve for a variable-credit section (default: the low end). Pins apply to this single-term draft only, not to unw_roadmap. include_summer=True also drafts the following summer for requirements that did not fit.

Multi-term plan starting at start_term (default: the start term plus three non-summer terms; summer only when include_summer). Carries requirements and prerequisites forward, reports terms with no published catalog, and returns graduation-risk notes against the audit's anticipated graduation term. Course pins, minimum-load and instructor exclusions are draft-only: use unw_plan_draft for those.

Offering pattern per course/attribute across every observed term: every-term, fall-only, spring-only, summer-only or never observed, with section counts, open counts and instructors per term. Accepts "CYS 4245", "ATTRIBUTE NATS" or "DAL *". Omit courses for every unmet requirement target. Use this before proposing a course for a future term.

List the student's Banner Plan Ahead worksheets for one term. Plans are TERM-SCOPED: this list only contains plans whose planHeader.term equals term; an empty list means "no plans for THIS term", not "no plans exist" (check other terms, and remember the session term must be bound).

Create a named Banner Plan Ahead worksheet for term (writes to Banner).

Confirmation is ENFORCED, not advisory: confirm is required and must be true, otherwise the tool returns the intended effect and the current plan count without writing. Verify the effect with the user first. The student may hold at most five plans per term; names cannot be renamed later.

Add a section (crn) or a course (subject+number) to a Banner plan (writes to Banner).

Confirmation is ENFORCED: confirm is required and must be true, otherwise the tool names the exact section/course and current plan state and performs no write. plan is an id or exact name; ambiguous names are rejected with candidates. Successful writes return a before/after diff read back from Banner.

Remove one course row from a Banner plan (writes to Banner).

Confirmation is ENFORCED: confirm is required and must be true, otherwise the tool names the exact row and projected credits and performs no write. Identify the row by crn or subject+number; plan is an id or exact name. Successful writes return a before/after diff read back from Banner.

Delete an entire Banner plan (writes to Banner, irreversible).

Confirmation is ENFORCED twice: confirm must be true AND confirm_name must equal the plan's exact name. Otherwise the tool reports the intended deletion and current plan state and performs no write. Successful deletion returns the removed plan, remaining plan count and a before/after diff read back from Banner.

DRY RUN ONLY: never posts add/drop/register. Returns Banner's real term eligibility flags and failure text for term, then local checks for the requested CRNs: seats/availability, time conflicts and prerequisites (prereq_ok is null when unverified). If Banner reports the term as ineligible, treat its failure text as the answer; never attempt real registration.

READ-ONLY registration time-ticket window(s). With term, returns that term's window; without it, returns the configured current term and the next selectable term. Each row carries Banner's verbatim eligibility failure text, parse_status (parsed/no_ticket/not_eligible/unknown), America/Chicago start/end, seconds until opening and a countdown. It NEVER registers, adds, drops or withdraws; parse_status=unknown must be reported from raw_text.
