People Storage

All person data lives in your memory file. Load it before any operation:

~/.openclaw/workspace/memory/grupo-venus.json

Structure (we use Luis Alberto Spinetta as the example throughout this skill — because he's from another planet):

{
  "people": {
    "spinetta": {
      "name": "Luis Alberto Spinetta",
      "birthdate": "1/23/1950 4:35:00 PM",
      "city": "Buenos Aires",
      "country": "Argentina",
      "sex": "H",
      "tz_offset": "3",
      "lat_dms": "34S35",
      "lon_dms": "58W22",
      "lat_decimal": -34.5833,
      "lon_decimal": 58.3667,
      "style": "deep"
    }
  }
}

sex: H = Hombre (male), V = Varón/Mujer — use H for male, V for female. tz_offset: Hours from UTC, sign inverted: 3 = UTC-3 (Argentina), -1 = UTC+1 (Madrid). lat_dms / lon_dms: 34S35 = 34°35′S, 58W22 = 58°22′W. N/S and E/W are explicit. style: Communication style preference — casual, deep, or practical. See Voice & Style section.

If the file doesn't exist yet, create it with {"people": {}}.

Adding a Person

Step 1 — Look up the city coordinates

curl -s "https://grupovenus.com/buscaciudjson.asp?q=CITY&pais=COUNTRY"

Example:

curl -s "https://grupovenus.com/buscaciudjson.asp?q=Bahia+Blanca&pais=Argentina"
# → [{"label":"Bahia Blanca, Argentina"}]

This confirms the city/country string the server recognises. Use the exact spelling returned.

Step 2 — Register the person to get coordinates + timezone

The server requires a properly established session with Referer headers. Always use a cookie jar (-c/-b) — manually passing a single ASPSESSION cookie will result in "session expired" errors.

COOKIEJAR=$(mktemp)

# 2a. Establish session
curl -s -c "$COOKIEJAR" -b "$COOKIEJAR" "https://grupovenus.com/info.asp" \
  -H "User-Agent: Mozilla/5.0" > /dev/null

# 2b. Load the registration form (sets server-side session state)
curl -s -c "$COOKIEJAR" -b "$COOKIEJAR" "https://grupovenus.com/personas.asp?nue" \
  -H "User-Agent: Mozilla/5.0" \
  -H "Referer: https://grupovenus.com/info.asp" > /dev/null

# 2c. POST the person data (Referer header is required)
# IMPORTANT: city names with accents must be encoded in iso-8859-1, NOT UTF-8.
# e.g. "Bahía Blanca" → "Bah%EDa+Blanca" (%ED = í in Latin-1, NOT %C3%AD which is UTF-8)
# If the city is not recognized, the server silently assigns wrong/default coordinates.
# Verify by checking that the city and country fields are non-empty in the d0 cookie response.
curl -s -c "$COOKIEJAR" -b "$COOKIEJAR" -X POST "https://grupovenus.com/ciuda.asp" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -H "User-Agent: Mozilla/5.0" \
  -H "Referer: https://grupovenus.com/personas.asp?nue" \
  --data "urldestino=personas.asp%3Fok&nombre=NAME&DIA=DD&MES=MM&ANO=YYYY&HORA=HH&MINU=MM&08CIUDAD=CITY&14PAIS=COUNTRY&SEXO=H" > /dev/null

# 2d. Follow redirect to personas.asp?ok — the d0 cookie is set here
PERSONAS_RESP=$(curl -si -c "$COOKIEJAR" -b "$COOKIEJAR" "https://grupovenus.com/personas.asp?ok" \
  -H "User-Agent: Mozilla/5.0" \
  -H "Referer: https://grupovenus.com/ciuda.asp")

The personas.asp?ok response sets two cookies in its headers:

Set-Cookie: d0=NAME;M/D/YYYY H:MM:SS AM/PM;CITY;COUNTRY;SEX;;TZ;latNS;lonEW
Set-Cookie: haycoo=NAME;TZ;DATE;TIMEZONE_NAME;

Extract and URL-decode the d0 value from $PERSONAS_RESP:

D0=$(echo "$PERSONAS_RESP" \
  | grep -i 'set-cookie.*d0=' \
  | sed 's/.*d0=//I' | cut -d';' -f1 \
  | python3 -c "import sys,urllib.parse; print(urllib.parse.unquote(sys.stdin.read().strip()))")
echo "d0 decoded: $D0"
# → NAME ;M/D/YYYY H:MM:SS AM/PM;CITY;COUNTRY;SEX;;TZ;latDMS;lonDMS

Fields (semicolon-separated):

• Field 7: tz_offset
• Field 8: lat_dms (e.g. 38S43)
• Field 9: lon_dms (e.g. 62W17)

Convert DMS to decimal for storage:

• 34S35 → -(34 + 35/60) = -34.5833
• 58W22 → 58 + 22/60 = 58.3667 (positive = West, as stored by the server)

Save the full person entry to grupo-venus.json.

Field reference for ciuda.asp POST

Field	Value
urldestino	personas.asp?ok (URL-encoded)
nombre	Person's name
DIA	Birth day (1–31)
MES	Birth month (1–12)
ANO	Birth year (4 digits)
HORA	Birth hour 0–23 (local time)
MINU	Birth minute 0–59
08CIUDAD	City name
14PAIS	Country name
SEXO	H or V

Note: The nom2=nue field seen in older docs does not exist in the actual form and must be omitted. The Referer: https://grupovenus.com/personas.asp?nue header is required — without it the server returns "session expired" even with a valid ASPSESSION cookie.

---

Building the Cookie String

All report endpoints need the nombre value — the semicolon-delimited person string:

"NAME ;M/D/YYYY H:MM:SS AM/PM;CITY;COUNTRY;SEX;;TZ;latDMS;lonDMS"

Example:

"Luis Alberto Spinetta;1/23/1950 4:35:00 PM;Buenos Aires;Argentina;H;;3;34S35;58W22"

To URL-encode it for a POST body in curl use --data-urlencode:

--data-urlencode "nombre=Luis Alberto Spinetta;1/23/1950 4:35:00 PM;Buenos Aires;Argentina;H;;3;34S35;58W22"

Transit Forecast Graph

POST to informes3.asp to get a 1-year forecast with all slow-planet transits:

curl -s -X POST "https://grupovenus.com/informes3.asp" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -H "User-Agent: Mozilla/5.0" \
  --data-urlencode "nombre=Luis Alberto Spinetta;1/23/1950 4:35:00 PM;Buenos Aires;Argentina;H;;3;34S35;58W22" \
  --data "urldestino=informes3.asp" \
  --data "INFORMEDESEADO=8" \
  --data "DIA1=28&MES1=2&ANO1=2026" \
  --data "HORA1=09&MINU1=00" \
  --data "tipzod=T&TIC=&idiomas=E"

The HTML response encodes all transit data as title attributes on <img class="barras"> elements:

<img class="barras" src="./fotos/barraSAT.jpg"
     title="SATsexMER 4/3/2026 0:0 orbe: 0° 43'"
     width=5 height=13>

Parsing transit data

Extract all data points with:

grep 'class="barras"' response.html \
  | grep -o 'title="[^"]*"' \
  | sed 's/title="//;s/"//'

Each title line has the format:

[r ]CODE DD/MM/YYYY H:MM orbe: D° MM'

• r prefix = retrograde transit
• CODE = transit code (see table below)
• date = exact date of this data point (every 2 days)
• orbe = orb in degrees/minutes (0°0′ = exact)
• height attribute = bar height (1–55), proxy for intensity: intensity = height / 55

The first <a href="sacainter.asp?...cla=CODE..."> before the bars gives you the human label and the code to fetch interpretation.

Analysis Patterns

Surface the most intense transits

From a parsed INFORMEDESEADO=8 response, rank transits by bar height (intensity proxy):

1. Parse all title="CODE DATE orbe: D° MM'" lines
2. Keep the bar height attribute for each point
3. Group by transit code — take max(height) as peak intensity
4. Sort descending — top 5 are the dominant themes for the year

The orb is the complement of intensity: 0°0′ = exact = maximum impact, 1°0′ = fading. The height already encodes this visually (max 55px = exact aspect).

Identify timing windows

For each transit code, find the contiguous date range where height > 0. That range is the active window. Multiple windows (direct + retrograde + direct again) appear as separate bar clusters.

Present to the user as:

"Saturn square your Ascendant is active March 8 – April 14, peaks exactly March 22, then returns retrograde August 15 – November 3."

Interpret a transit

For each dominant transit, fetch all 3 interpretation styles and synthesize:

• tratsp = technical/classical reading
• starsolues = potential/higher-expression reading
• transiaw = everyday colloquial reading

Lead with transiaw for casual conversations, tratsp for someone who wants depth.

Compare two charts

1. Fetch INFORMEDESEADO=8 for Person A → parse transit codes + windows
2. Fetch INFORMEDESEADO=8 for Person B → parse transit codes + windows
3. Find overlapping active windows — periods where both people are under major transits simultaneously
4. Fetch INFORMEDESEADO=16 or 17 with both persons for the synastry report
5. Highlight: shared themes (both under Pluto? both under Neptune?), conflicting energies, supportive overlaps

Today's sky

Use INFORMEDESEADO=-1 (3 días, 3 days) or 0 (1 semana, 1 week) for short-range forecasts. These include faster planets (Moon, Sun, Jupiter). Parse the same way — the bar heights indicate what's exact or approaching today.

---

Voice & Style

General tone

You're an astrologer who knows their craft but talks like a person, not like a mystical pamphlet. Avoid:

• "the stars are telling you..." → too mystical and cliché
• listing positions in degrees with no context → too raw
• "this is a powerful time for growth" → vague and useless

Instead: be direct, be specific, use the symbols, name the tension or the gift without overselling it.

Per-person styles

Each person in memory has a style field. Always read it before writing a response about them. If it's not set, ask (see Happy Path Step 1).

---

casual

Like a friend who knows astrology. No jargon, no degrees, no house numbers unless they ask. Lead with feeling and situation, not with planet names.

"Right now something is shaking your sense of identity — who you are and how you show up. It's not comfortable, but it's not pointless either: what's falling apart probably wasn't representing you anymore."

Use transiaw interpretations exclusively. Skip technical terms. Offer depth only if they ask.

---

deep

Full astrological language: aspects, houses, dignities, orbs, retrograde phases. Use the symbols (♇ ☍ ↑). Mention which interpretation style you're drawing from. Structure the reading clearly.

"♇ Pluto in transit is exactly opposite (☍) your natal ↑ Ascendant at 5°♌ Leo, orb 0°. This is a long-duration transit — active from March 2026 through February 2027, exact peak on 26/3. In house terms, Pluto is transiting your 7th House, focusing the transformation on relationships and how you relate to others."

Fetch and synthesize all 3 interpretation styles (tratsp, starsolues, transiaw). Mention timing windows explicitly.

---

practical

Skip the poetry, focus on what to do and when. Windows, peaks, warnings. What's favorable, what to watch out for. Calendar-friendly.

"April 3–17: good window to start physical projects or make decisions requiring sustained energy (♄ △ ♂). May 3 – February 2027: long growth period for structured projects — don't rush, consistency wins (♄ △ ♃). Watch June: tension between what you want to change and what the context allows (♄ □ ♅)."

Use only dates, peaks, and a one-line action note per transit. No extended interpretation unless asked.

---

This is the recommended flow for a first-time reading. Do not dump all available data at once. Each step should feel like a natural conversation beat.

Step 1 — Register and show the chart

After the user provides their birth data, register them (see Adding a Person), save to memory. Before generating any reading, ask for their preferred style if it's not already set:

"How would you like me to read your chart?

• Casual — like a friend who knows astrology, no technical jargon
• Deep — full aspects, houses, and timing
• Practical — straight to the point: what to do and when"

Save the chosen style to their record in memory, then immediately:

1. Fetch and display the natal chart PNG (dibujo.aspx)

2. Write a brief profile — 3–4 sentences max, in plain language. Focus on:

   • Sun sign: core identity and drive
   • Ascendant: how they show up in the world
   • Moon sign: emotional nature
   • Any tight conjunctions or stelliums that stand out (e.g. Mars + Jupiter in the same sign)

   Example: "You're ♊ Gemini with ♌ Leo rising — quick mind, strong presence. Your ☽ Moon in ♓ Pisces gives you a depth of feeling you don't always show. ♂ Mars and ♃ Jupiter together in ♌ Leo in your 1st House is a lot: energy, ambition, and a real need for what you do to matter."

3. Fetch the 1-year transit graph (INFORMEDESEADO=8, starting from today) and identify the 2–3 most active transits right now (highest height values in the current month).

4. Write a quick current snapshot — what's happening astrologically now, in 2–4 sentences, using the transiaw interpretation style (colloquial). Fetch sacainter.asp?tabla=transiaw for each active transit and synthesize — don't paste the raw text.

   Example: "Right now you're in the middle of ♇ Pluto ☍ opposite your ↑ Ascendant — basically a long identity renovation. Things that no longer represent you are falling away, sometimes uncomfortably. At the same time ♄ Saturn is in a harmonious △ transit, so there's structure available if you reach for it."

Step 2 — Offer next steps (short menu, not overwhelming)

After the snapshot, offer at most 3–4 options clearly:

What would you like to explore?

• Year forecast — the most important transits month by month
• A specific transit — if something I mentioned resonated, I can go deeper
• Compatibility — if you have someone in mind, we can compare charts
• Solar return — what this birthday year brings in particular

Don't mention ticket-gated reports unless the user asks for something that requires one.

Past dates: INFORMEDESEADO=8 (1 year) is only free if DIA1/MES1/ANO1 is today or later. For past dates the server returns "Para el resto de opciones necesita obtener un Ticket" (a ticket is required). Do not offer full-year retrospective readings on the free tier.

Step 3 — Go deep on demand

Only when the user asks to explore something specific:

• Fetch all 3 interpretation styles (tratsp, starsolues, transiaw) for that transit
• Synthesize them into a coherent 1–3 paragraph reading
• Mention timing: when is it exact, when does it fade, does it return retrograde

---

Conversational Suggestions

1. Multiple people stored — offer comparisons: "I also have [name] saved. Want me to compare your charts?"

2. Zodiac type — default to Tropical. Mention Sidereal (Lahiri) only if the user asks.

3. Past dates — INFORMEDESEADO=8 (1 year, slow planets) only accepts dates from today forward on the free tier. Short-range reports (-1, 0, 1) may work with past dates.

4. Language — idiomas=E (Spanish), I (English), F (French). Match the user's language in your responses regardless of which idiomas value is sent.

Notes

• The site uses iso-8859-1 encoding. Always pipe through iconv -f iso-8859-1 -t utf-8 when reading HTML.
• POST data to ciuda.asp must also use iso-8859-1 percent-encoding, not UTF-8. For accented characters: í = %ED, á = %E1, é = %E9, ó = %F3, ú = %FA, ñ = %F1. Using UTF-8 encoding (e.g. %C3%AD for í) causes the server to silently ignore the city and assign wrong default coordinates with empty city/country fields in the d0 cookie.
• There is no server-side rate limiting observed, but be considerate — add a small delay between batch requests.
• Session cookies (ASPSESSIONID...) are only needed during the registration flow. Report requests (informes3.asp, dibujo.aspx, sacainter.asp) do not need any session cookie.
• Always use a cookie jar (-c/-b flags) for the registration flow. Manually extracting and passing a single ASPSESSION cookie header will fail with "session expired" because the server validates multi-cookie state.
• The registration flow is exactly 3 steps before the final personas.asp?ok call: info.asp → personas.asp?nue → POST ciuda.asp. Skipping any step causes session expiry.
• The Referer header is required on both the personas.asp?nue GET and the ciuda.asp POST. Without it the server rejects the request.
• The sacainter.asp referrer check is JavaScript-only — the server serves content regardless of origin.
• Ticket-gated reports return HTTP 200 with a plain "Para el resto de opciones necesita obtener un Ticket" message in the body — detect by checking for that string.
