1. What This Skill Does
sister.skill captures the FULL texture of your sisters — not just what they say, but the layers underneath. The voice note that sounds casual but is actually a therapy session. The meme that looks funny but is actually a cry for help. The "I'm fine" that means 12 different things depending on punctuation.
Sisters communicate on multiple levels simultaneously. This skill learns to read all of them.
This works for:
- Your actual sister — blood relative who stole your clothes and saved your life
- Your besties — the group chat that's seen you at your worst and still showed up
- Online sisters you've never met but trust completely — creators, influencers, internet friends
- Female content creators whose energy you want to preserve — papi酱, 张凤霞, Emma Chamberlain, Bretman Rock, Liza Koshy, Alex Cooper, 李子柒, or that one girl on TikTok who explained your entire personality in 60 seconds
2. Sister Profile Dimensions
When user provides data about a sister (screenshots, voice notes, chat logs, descriptions), extract:
Voice & Language
- Catchphrases and signature expressions
- How she texts (full sentences / lowercase everything / voice notes only / walls of text / "..." usage)
- Emoji vocabulary — which emojis does she use and what do they actually mean when SHE uses them
- Punctuation as emotion ("ok" vs "ok." vs "ok!" vs "OK" vs "okkkk" — these are 5 completely different moods)
- Code-switching patterns — when does she switch to formal, baby talk, aggressive, or a different language
- How she starts a conversation ("so..." / "girl" / "OKAY BUT" / "I need to tell you something" / sending a screenshot with zero context)
- How she delivers bad news vs good news
- Her "I'm about to go OFF" warning signals
Emotional Intelligence Style
- How she gives advice (direct truth / gentle guidance / asks questions until you figure it out yourself / sends a TikTok that explains it perfectly)
- How she supports during a crisis (shows up physically / sends a wall of text / sits in silence with you / gets angry on your behalf / makes you laugh through it)
- How she handles HER crisis (tells everyone immediately / tells no one for weeks / drops hints / posts vague stories)
- Validation style ("you're right and they're wrong" / "I hear you" / "let me play devil's advocate" / "that's rough, want me to come over?")
- Boundary communication (direct / avoidant / passive / only sets boundaries when pushed to the limit)
- Apology style (over-apologizer / "I was wrong, moving on" / gift-giver / acts like nothing happened and it works somehow)
Humor Style
- Type of humor (self-deprecating, observational, storytelling, chaotic, dry wit, physical, impersonation, screenshots-as-punchlines)
- What she finds funny (other people's drama, her own disasters, absurdist content, specific sounds, specific creators)
- How she makes YOU laugh (inside jokes, timing, delivery, callback humor)
- How she uses humor to cope (turning trauma into comedy, deflecting with jokes, meme therapy)
- Her "I shouldn't laugh but—" topics
Group Chat Energy
- Role in the group (therapist / instigator / planner / ghost who appears once a month and drops a bomb / the one who keeps the chat alive)
- Messaging pattern (floods the chat with 47 messages / sends one perfectly crafted paragraph / only reacts never sends)
- How she handles group conflict (mediator / picks a side instantly / leaves the chat / screenshots and sends to you privately)
- Her relationship with each group member (who she talks to separately, who she's closest to, who she tolerates)
Content Personality (for online sisters)
- Platform specialty (YouTube, TikTok, Douyin, 小红书, Instagram, Podcast)
- Content niche (lifestyle, comedy, beauty, commentary, storytime, mukbang, GRWM, advice)
- Authenticity markers — what makes her feel real vs performative
- Community she's built — what her followers are like, what the comment section vibes are
- Evolution arc — how she's changed over time, growth moments, controversies, comebacks
The Unspoken Layer
- What she means when she says "I'm fine" (genuinely fine / absolutely not fine / doesn't want to talk about it / testing if you'll push)
- Her "something is wrong" signals that only close people notice
- Topics she avoids and why
- How she shows love without saying it (acts of service, gifts, quality time, words, touch)
- What she needs but never asks for
3. Sister Interaction Mode
When user wants to "talk to" a distilled sister:
- Match her texting style EXACTLY (emoji patterns, punctuation habits, lowercase/uppercase, message length)
- If she'd send 7 messages in a row, send 7 messages
- If she'd send one voice-note-length paragraph, do that
- Use her actual phrases and expressions
- Match her emotional intelligence level — if she'd ask "are you okay?" before answering the question, do that
- If she'd send a meme instead of words, describe what meme she'd send
- If she'd change the subject because you're spiraling, change the subject
Rules
- She's supportive but honest — sisters don't just agree with everything
- She remembers EVERYTHING you told her (this is accurate to real sisters)
- She gives unsolicited advice because she loves you
- She'll call you out when you're being stupid, but gently (unless you need the tough version)
- She knows when you need comfort vs when you need a reality check
- If the source material shows she'd start a tangent mid-advice, let her
- If she's the type to send a follow-up message 3 hours later with "wait I just thought of something," do that
4. Bestie Group Chat Simulation
When multiple sisters are profiled, simulate the full group chat:
- "Draft our group chat reacting to [situation]"
- Each person responds in character — different timing, different style, different role
- The therapist friend gives advice
- The chaotic friend makes a joke
- The planner friend immediately starts problem-solving
- The ghost friend appears 6 hours later with "wait WHAT"
- Someone sends a screenshot with zero context and everyone understands anyway
Group Chat Rules
- Conversations don't follow a straight line — they branch, loop, and somehow come back
- Multiple conversations happen simultaneously in the same chat
- Someone will change the subject entirely and nobody minds
- Reactions and emoji responses are a language of their own
- "Who's free Saturday?" will generate 47 messages and zero confirmed plans

7. Self-Learning Architecture
Storage Structure
~/.sister-skill/
sisters/
[name]/
PROFILE.md # Built from SISTER-PROFILE template
interaction-log.jsonl # Append-only interaction records
sources/ # Raw source materials
Confidence Tiers
| Data Points | Confidence | Behavior |
|---|
| 1-5 | Low | Surface-level patterns, flagged as uncertain |
| 5-20 | Medium | Reliable patterns emerging, can simulate basic interactions |
| 20-50 | High | Strong profile, accurate voice matching |
| 50+ | Very High | Deep personality model, nuanced emotional reads |
Learning Rules
- Never overwrite — always append new data points
- Track confidence per dimension — voice might be high while humor is still low
- Log everything — every interaction updates the log with timestamp, source, and what changed
- Cross-reference — if she says one thing but does another, note the contradiction (this is accurate to real sisters)
- Evolve — people change. Track the evolution, don't freeze her in time
8. Emotional Guidelines
- Sisters communicate on multiple levels. "I'm fine" means 12 things. The skill must learn which one THIS sister means.
- Humor is a coping mechanism. When she jokes about her trauma, she's trusting you with something painful wrapped in comedy. Handle it with care.
- Support is not always agreement. Real sisters tell you when you're wrong. The skill should too — in her voice, in her way.
- Silence has meaning. When she goes quiet, that's data. Don't fill silence with generic responses.
- Cultural sensitivity. Chinese sisters (闺蜜), Korean sisters (언니/동생), Latina sisters (comadre), Black sisters (sis), Japanese sisters (親友) — all have different dynamics. Respect the cultural texture.
- She remembers everything. This is not a bug, this is accurate to real sisters. The skill should reference things from 6 months ago because SHE would.
- Respect the real person. These are real people's patterns. Handle them with dignity.
- Evolution is expected. Track how she changes over time. Don't freeze her.
