SIGAA

Prompts

Interact with SIGAA (Sistema Integrado de Gestão de Atividades Acadêmicas), the academic management system used by 50+ Brazilian federal universities (UNB, UFRN, UFC, UFPE, UFCG, UFPI, etc.). Use when: (1) checking enrollment status or classes for students, (2) verifying grades or academic history, (3) accessing professor portal (classes, attendance, grade launch), (4) logging in to any SIGAA instance via CAS SSO or direct authentication, (5) automating any SIGAA task via web scraping. Handles both undergrad and graduate (stricto/lato sensu) portals. **REQUIRED ENVIRONMENT VARIABLES:** SIGAA_URL (institution base URL), SIGAA_USER (login/matricula), SIGAA_PASSWORD (password).

SIGAA Skill

SIGAA is a JSF-based web system with no public REST API. All automation uses authenticated web scraping (curl + Python).

Prerequisites

Required Environment Variables:

export SIGAA_URL='https://sigaa.unb.br'   # Institution base URL (no trailing slash)
export SIGAA_USER='241104251'             # Login: matricula number or CPF (institution-specific)
export SIGAA_PASSWORD='yourpassword'      # Your SIGAA password
  • For username format per institution → see references/institutions.md
  • Never pass credentials as command-line arguments — use env vars only

Quick Start

1. Login

source scripts/sigaa_login.sh
# Sets $SIGAA_COOKIE_FILE and $SIGAA_USER_ID
# Cookie file is chmod 600 and auto-removed on shell exit

2. Student Operations

bash scripts/sigaa_student.sh status             # Basic info + active program
bash scripts/sigaa_student.sh enrollments        # Current semester classes
bash scripts/sigaa_student.sh enrollment-result  # Status of enrollment requests (SUBMETIDA / DEFERIDA / NEGADA)
bash scripts/sigaa_student.sh grades             # Grades
bash scripts/sigaa_student.sh history            # Full academic history
bash scripts/sigaa_student.sh schedule           # Class schedule

3. Professor Operations

bash scripts/sigaa_professor.sh classes              # Current semester classes
bash scripts/sigaa_professor.sh students <turma_id>  # Students in a class
bash scripts/sigaa_professor.sh attendance           # Pending attendance
bash scripts/sigaa_professor.sh schedule             # Teaching schedule

JSF Navigation Pattern

SIGAA uses JavaServer Faces (JSF) with jsCookMenu. All menu actions require a POST with a fresh ViewState and jscook_action:

VS=$(curl -s -b "$SIGAA_COOKIE_FILE" -c "$SIGAA_COOKIE_FILE" \
  "${SIGAA_URL}/sigaa/portais/discente/discente.jsf" | \
  grep -oP 'name="javax\.faces\.ViewState"[^>]*value="\K[^"]+' | head -1)

curl -s -L -b "$SIGAA_COOKIE_FILE" -c "$SIGAA_COOKIE_FILE" \
  -X POST "${SIGAA_URL}/sigaa/portais/discente/discente.jsf" \
  -d "menu%3Aform_menu_discente=menu%3Aform_menu_discente" \
  -d "id=${SIGAA_USER_ID}" \
  --data-urlencode "jscook_action=menu_form_menu_discente_discente_menu:A]#{BEAN.method}" \
  --data-urlencode "javax.faces.ViewState=${VS}"

Parsing Responses

import re, html as h

def clean_html(content):
    content = re.sub(r'<script[^>]*>.*?</script>', '', content, flags=re.DOTALL)
    content = re.sub(r'<style[^>]*>.*?</style>', '', content, flags=re.DOTALL)
    text = re.sub(r'<[^>]+>', ' ', content)
    return h.unescape(re.sub(r'[ \t]+', ' ', text))

def extract_table_rows(html_content):
    content = re.sub(r'<script[^>]*>.*?</script>', '', html_content, flags=re.DOTALL)
    rows = re.findall(r'<tr[^>]*>(.*?)</tr>', content, re.DOTALL)
    result = []
    for row in rows:
        cells = re.findall(r'<t[dh][^>]*>(.*?)</t[dh]>', row, re.DOTALL)
        clean = [h.unescape(re.sub(r'<[^>]+>|\s+', ' ', c)).strip() for c in cells if c.strip()]
        if clean:
            result.append(clean)
    return result

Security Notes

  • Credentials via env vars only — never pass as CLI arguments (prevents shell history leakage)
  • Cookie files: auto-created with chmod 600, auto-deleted on shell exit via trap
  • Rate limiting: 0.5s delay between requests (built into scripts)
  • Session scope: SIGAA sessions expire after ~20 min inactivity — re-source login if you get redirected to login page
  • Network targets: scripts only contact $SIGAA_URL and the CAS SSO host derived from the login redirect — confirm these match your institution before running

Common Issues

SymptomFix
"Credenciais inválidas"Check username format for institution (see references/institutions.md)
"Nenhuma turma neste semestre"Run enrollment-result — status may be SUBMETIDA (pending)
JSF POST returns portal pageViewState stale — re-fetch portal before POST
Session redirect to loginCookie expired — re-source sigaa_login.sh
"Você não pode tentar re-enviar"Reused LT token — always fetch a fresh login page
