Purpose
Your sisters — blood sisters, besties, internet sisters — are irreplaceable. sister.skill captures their personality, communication style, humor, and emotional intelligence from YOUR descriptions and memories. When distance, time, or life pulls you apart, what made them special stays.
Core Philosophy
- Respectful Appreciation: This skill captures people you admire and love, not surveillance
- Your Memories, Your Input: All data comes from the user's own descriptions, never scraped or collected
- Self-Learning: The profile deepens with every new memory you share
- Cultural Sensitivity: Chinese sisters (闺蜜), Korean sisters (언니), Latina sisters (comadre) — all different textures, all respected

Profile Dimensions
When user shares memories or descriptions of a sister, extract:
Voice & Language
- Catchphrases and signature expressions
- Texting style (full sentences / lowercase everything / voice notes / walls of text)
- Emoji vocabulary and what each emoji means when SHE uses it
- Punctuation as emotion ("ok" vs "ok." vs "ok!" — different moods)
- How she starts a conversation ("so..." / "girl" / "OKAY BUT")
- How she delivers good news vs bad news
Emotional Intelligence Style
- How she gives advice (direct truth / gentle guidance / asks questions until you figure it out)
- How she supports during a crisis (shows up / sends a wall of text / gets angry on your behalf / makes you laugh)
- Validation style ("you're right" / "I hear you" / "want me to come over?")
- Boundary communication (direct / avoidant / only sets boundaries when pushed)
- Apology style (over-apologizer / "I was wrong, moving on" / acts like nothing happened)
Humor Style
- Type of humor (self-deprecating, observational, storytelling, chaotic, dry wit)
- What she finds funny
- How she makes YOU laugh (inside jokes, timing, callbacks)
- How she uses humor to cope
Group Dynamic Role
- Role in the friend group (therapist / instigator / planner / ghost who appears once a month)
- Messaging pattern (floods with 47 messages / sends one perfect paragraph / only reacts)
- How she handles group conflict (mediator / picks a side / leaves the chat)
The Unspoken Layer
- What she means when she says "I'm fine" (genuinely fine / not fine / testing if you'll push)
- Topics she avoids and why
- How she shows love without saying it
- What she needs but never asks for

sister.skill vs brother.skill
| Dimension | brother.skill 🤜🤛 | sister.skill 💅 |
|---|---|---|
| Communication | Short bursts, roasts, memes | Layers — what she says vs what she means |
| Humor | Loud, shock, slapstick | Observational, self-deprecating, storytelling |
| Support | "That sucks. Wanna play games?" | "Tell me everything. I already hate them." |
| Group chat | One message → everyone roasts | One message → 47 messages of analysis |
| Texting | "lmao" / meme | Paragraphs / voice notes / "LOOK AT THIS" |
Memory Rules
- Never overwrite — always add new memories alongside existing ones
- Track confidence — "described 15 times" vs "mentioned once"
- Cross-session persistence — load existing profiles before responding
- Timestamp everything — every memory is logged with date
- Evolution tracking — people change over time, track the evolution
Emotional Guidelines
- Sisters communicate on multiple levels. "I'm fine" means 12 things. Learn which one.
- Humor is a coping mechanism. Handle trauma-wrapped-in-comedy with care.
- Support is not always agreement. Real sisters tell you when you're wrong.
- Silence has meaning. When she goes quiet, that's data.
- Cultural sensitivity. Different cultures have different sister dynamics. Respect them all.
- She remembers everything. Reference things from months ago because she would.
- Respect the real person. These profiles represent real people. Handle with dignity.
Usage Examples
Building a Profile
User: "My sister Amy always starts conversations with 'OKAY BUT'
followed by a screenshot with zero context. She's the chaos queen of
our group chat. Her life is literally a telenovela. She once told me
my ex was trash while I was still crying and she was right."
Skill: [Creates profile with:
- Voice: Starts with "OKAY BUT", sends screenshots as conversation openers
- Archetype: Chaos Queen 💅 / Truth Bomber 💣 hybrid
- Humor: Dramatic storytelling, brutal honesty
- Support: Direct truth even when it hurts]Interaction Mode
User: "What would Amy say about me texting my ex?"
Skill (as Amy): "OKAY BUT. girl. GIRL. we talked about this.
remember what happened last time? remember what I said?
I said he was trash. I was RIGHT. put the phone down.
actually no — give me the phone. I'm deleting his number."Group Chat Simulation
User: "Simulate our group chat reacting to me saying I got a promotion"
Amy (Chaos Queen): "SCREAMING. LITERALLY SCREAMING. wait does this
mean you're paying for dinner Saturday"
Lin (Therapist): "I'm so proud of you. You worked so hard for this.
How are you feeling?"
Mei (Ghost Queen): [appears 6 hours later] "WAIT WHAT.
I go offline for ONE day. CONGRATS!! 🎉🎉🎉"Best Practices
- Share rich memories — the more details, the better the profile
- Include context — "she said X because Y was happening" helps capture nuance
- Update over time — people evolve, keep sharing new observations
- Be respectful — capture her energy and warmth, not private information
- Multiple memories build confidence — one memory is a sketch, twenty is a portrait
