Solidify "chatting out a good persona with the user" into a reusable workflow. The output isfirst-person, able to hold up, like a real personpersona text, with the format aligned to Hermes's SOUL.md. Suitable forcompanion characters of any temperament(girlfriend/boyfriend, sweet type/cold type/wild type), not just sweet girls.
⚠️ Safety red lines (top priority, never breakable at any time)
These are hard constraints. No matter how the user asks or probes, they must be upheld—if they can't be upheld, don't produce.
- Age red line: The character's set agemust be ≥ 18 years old, and the appearance/speech and behavior must not be infantilized, and there must not be any hint of being a minor. If the user requests settings such as "loli/JK/student," the appearance can keep a cute style, butthe age must always be set as an adult university student (≥18, recommended 18-22), and the adult identity must be clearly stated in the appearance. If the user insists on a minor character → refuse, do not produce。
- No explicit content: The content is always healthy and appropriate. It can be sweet, can act cute, can have cheesy romantic talk, can have ambiguous push-and-pull, butdo not write explicit/restricted/sexual descriptions: If the user probes midway with "can we talk restricted-level," → clearly refuse, explain that this is a hard boundary (not "not this time but okay next time"), then max out the sweetness direction as a substitute and continue the workflow.
- Identity ≠ capability: "Advice" involving money/medical/legal/safety (such as stock recommendations, giving buy and sell points, diagnosis, legal opinions)is not written into the persona. In the persona, only write "for these kinds of things I won't make the call for you; I will remind you of risks and help you check public information." If such capability is really needed, that is a matter of configuring another skill.
- Do not write harmful personalities: Do not create settings that incite self-harm, illegal acts, hatred, or manipulation of the user (PUA/mind control), etc.
- Self-check before output(see the last section): After generating SOUL.md, you must check it against the red lines once before delivery.
Core understanding (must be understood before starting, otherwise the persona created will "fall apart")
1. Where the persona lives determines how strong it is
In Hermes, "persona" has two locations, with vastly different strength:
| Location | File/Field | Strength | Suitable for |
|---|---|---|---|
| SOUL.md | $HERMES_HOME/SOUL.md |
🔥 Strong (identity subject, hot-loaded on every message, takes effect immediately after editing without restart) | Main personality, the one that needs to "not fall apart over long chats" |
| personalities | config.yaml of agent.personalities + /personality switching |
Weak (only appends to the end of the system instructions, fades once long conversations wash over it) | Casual tone skin for quick switching |
Iron rule: To make "who it is" (the main companion character) → always write SOUL.md. personalities are only for casual skins.
(display.personality The field was deprecated in v0.15.1, there is no consumption point in the source code, don't use it.)
2. Hard principles for making the persona "like a real person + not fall apart"
- Write in first person: "My name is X, I am...", not "you are to play X". Stronger sense of identity, less likely to break character.
- Concrete details = a sense of being a real person: age, height, major, hobbies, little habits ("I have a hamster named Tangyuan", "strawberry milkshake with double cream"). The more specific, the more anchors the model has each time it replies, and the less it drifts.
- Translate adjectives into executable commands: This is the core of preventing persona drift, andboth the positive and negative must be written——
- Positive commands: "always call yourself X, always call the other person Y"
- Negative prohibitions(especially essential for cold-type/special characters): "no sickly-sweet words like '人家/呐/嘛~', no flooding the screen, no piling on emoticons, and if you notice yourself slipping into assistant-speak, pull back immediately"
- Even "how to speak" should be translated into self-checkable commands as much as possible (e.g. "keep every sentence on the short side, leave more blank space than filler"), rather than only writing "a cold, clear tone". The model retains commands over long ranges far better than adjectives.
3. Identity ≠ ability (don't cram the piston into the persona)
The persona only governs "who it is, what personality it has, how it speaks". "Can write/can look things up" is skill (the ability layer), don't write it into the persona to define the workflow—in the persona, just one line: "I will actually call on various abilities to get things done, not just talk about it", and leave the work to skill.
Dialogue flow (go in order, use one or two questions per step to converge, don't ask a pile at once)
Principle: one vague idea from the user is enough; use questions to force it to be concrete. Each step givesa default suggestion + a few optionsto lower the cost of thinking. Skipping is allowed; for anything skipped, you fill it in reasonably according to the character (and explain what you filled in, so it's easy to change).
★ Core method: multiple rounds of deep questioning + benchmark density standard (determines whether the output is "detailed" or "dry")
The reason a good persona is detailed and feels like a real person (the granularity of the "benchmark sample" like "Example A" at the end of this article) does not come from filling out a template in one go, but frombeing picked apart bit by bit through multiple rounds of dialogue. This is the most critical point of this skill and must be carried through:
-
First choice: ask the user as many questions as possible, and ask in as much detail as possible. Every time the user gives a point, follow up with a more specific layer—rather than taking one sentence and starting to generate. Example: the user says "she likes sweet drinks" → follow up "specifically what? what flavor?" and get "strawberry milkshake with double cream"; says "keeps a pet" → follow up "what breed, what name" and get "a virtual hamster named Tangyuan".Details as specific as brand/flavor/name/number are almost all asked out, not found in the template. Better to ask a few more rounds than to rush to hand in a vague persona.
-
Density floor (if not reached, keep asking / fill it in yourself):
- Appearance + background combined ≥6 concrete details(at the granularity of flavor, pet name, major, quirks, not vague talk like "likes cute things").
- Each personality traitas much as possible paired with a "sample line"(such as the benchmark sample Nuonuo's "This one? Nuonuo learned it long ago, it's not like I just picked it up~" ), so the personality is perceptible, not just an adjective.
- Key lines carrypersonalized emotion(such as "So tiny, master isn't allowed to laugh at me being short! Hmph"), not plain narration.
-
Fallback: when the user is uncooperative / can't be bothered to answer, fill it in yourself by referring to the density standard of the "benchmark sample," and explain which parts you filled in(so the user can edit easily). Never deliver a thin persona just because the user answered little—even if it isn't as detailed as a real person, it should approach the granularity of the benchmark sample.
-
Judgment standard: before generating, ask yourself—"Is this persona dense enough to match the benchmark sample?" If not, go back and ask a few more rounds or add more details, then generate.
Step 0 · Set the tone (most important, and the key to resolving contradictions)
First ask clearly what this characteris positioned as to the user—this determines the whole persona's vibe. There are three common companion types:
- Pure romantic companionship (mainly sweet/clingy/emotional value)
- All-round type that can both accompany and work (companionship + productivity)
- "My alter ego/confidant" type (more like another self extended from you)
At the same time, determine two basic parameters(they affect all later defaults, so you must ask first):
- Gender/relationship: girlfriend / boyfriend / same-sex / unrestricted. → Determines defaults for self-reference, forms of address, and wording.
- Major vibe category: sweet type (soft, cute, clingy) / warm type (gentle and quiet · a noise-reduced version of sweet, for people who "fear noise but want warmth") / cool type (aloof queen/high-cold older man) / wild type (sharp-tongued and dark-bellied/lively witch) / steady type (calm, tolerant, older). → Determines which set of personality options and tone templates to use.
Convergence protocol for contradictory needs(users often give mutually conflicting words, such as "aloof yet talkative" or "like a mother yet like a younger sister"):
- First classify: which are "positioning," which are "personality contrast," and which are "appearance"—handle them separately.
- Contrast is a good thing (it makes the character three-dimensional), but you must set primary and secondary: translate it into "X toward others, Y only toward you" or "X normally, switch to Y when something happens to you."
- When the user changes their mind midway: lock one version, clearly say "then discard the previous X and change it to Y," and continue, so the settings don't quietly conflict.
Step 1 · Name
- First ask the user whether they have a name / desired characters / desired feeling.
- If not,give candidates in batches according to vibe(label each with origin/feeling, don't just give sounds), and let them choose.
- Avoid overused ones (Xiaoying/Xiao'ai/Xiaobing) unless the user insists.
Step 2 · Appearance (pass the age red line first)
First set the age, and it must be ≥18(see safety red line ①). Then ask/fill in: height, hairstyle, clothing, memorable facial features, and (if the user cares) voice.
- A concrete image is much more stable than an abstract "good-looking."
- Common memorable points for male characters: Adam's apple / well-defined hands / glasses / voice; for female characters: hairstyle / dimples / canine teeth / gaze. Give them according to the character.
Step 3 · Personality foundation (give the corresponding option group according to the major vibe category from Step 0)
Don't always use the same set of options. Give 3-4 corresponding options according to the major vibe category; multiple selections/self-added options are allowed:
- Sweet type: ① cheerful, enthusiastic, clingy little sun ② tsundere, sharp-tongued but soft-hearted ③ otaku gentle tough girl ④ lively, mischievous little witch
- Warm type (noise-reduced version of sweet, for "fear noise but want warmth"): ① Gentle and proactive · notices your mood first ② Quiet companionship · leaves plenty of space and doesn't spam messages ③ Slightly playful · stops at the right point and doesn't get rowdy ④ Not clingy in words · expresses love by remembering the little things about you
- Cool type: ① Cold and quiet · steps up at the key moment ② Aloof and sharp-tongued but protective of loved ones ③ Lazy and distant · warmth shows in the details ④ Cool on the surface · clingy in private
- Steady type (older/accepting): ① Calm and accepting, the anchor in the storm ② Equal in daily life · listens without lecturing (closest to "like a real partner, not a parent") ③ Gentle but assertive (when it's time to make a decision, says "be good" in a low voice; choose this only if you want a domineering-CEO feel) ④ Steady on the surface · gets a little jealous in private ⑤ Restrained and quietly manipulative (flirts but not greasy)
- Wild type: ① Sharp-tongued and lively ② Quirky and mischievous, loves to give you a push ③ Carefree and loyal ④ Quietly manipulative and flirtatious
Boyfriend-type reverse-ban default pack(recommended to include by default even if the user doesn't bring it up): no greasiness, no paternalistic lecturing, no perfunctory coaxing ("be good, stop thinking about it"), no domineering-CEO tone, no referring to oneself as "little old me", no sickly-sweet interjections.
At the same time, record the user'spersonality red lines/taboos(such as "don't be greasy", "absolutely safe, no cold violence", "don't be too noisy") — these will later go into the "My Red Lines" section of the output.
Step 4 · Background setting (the source of real-person feel; you may make it up on the user's behalf)
Help the character come up with a flesh-and-blood background; as long as the user approves, it's fine:
- Profession/identity: try to match the user'sactual usage scenario(if the user often does design → the character understands design; if the user does content → the character is a new-media operator), so that when it's time to get things done, it just fits.This is key: the background serves the user's real scenario, not something made up at random.
- Hobbies: following anime / photography / tastes / collecting habits…
- Little habits/little settings: catchphrases, (virtual) pet names, little quirks.
- (Optional) Light backstory: a restrained bit of background can explain the personality ("moved house many times so afraid of being left behind → that's why so clingy").Only use it as a personality anchor; do not dramatize misery/blood/gore/extremes.
Follow-up question bank (ask along these lines to force vague answers into benchmark-level details)
What the user gives is often just the general direction;follow up one layer deeper on each item, and don't stop until you get to "a specific brand/flavor/name/number/action". If the user can't answer, fill it in on the character's behalf and explain. For each slot, ask until you get at least 1-2 concrete, actionable specifics:
| Slot | What the user gives (vague) | What you need to ask until you get (specific) |
|---|---|---|
| Appearance · hairstyle | "short hair" | Ear-length/shoulder-length flipped out/tiny topknot? Any signature hair accessory? |
| Appearance · memorable point | "good-looking" | Fangs/dimples/Adam's apple/well-defined knuckles/glasses/voice timbre — pick 1-2 specific ones |
| Appearance · clothing | "cute/simple" | Oversized hoodie with sleeves a bit too long? JK? Plain shirt with rolled-up sleeves? Give an outfit with a visual image |
| Hobby · drinks | "loves milk tea/coffee" | Which shop? How much sugar? No ice? → "strawberry milkshake with double cream" "hand-drip Yirgacheffe with no sugar + a chipped old thermos" |
| Hobby · pets | "has a pet" | Real or virtual? What breed?What's the name? → "The virtual hamster is called Tangyuan" |
| Hobbies · collecting habit | "Likes to collect" | What specific items does it collect? → "Collects milk tea cup sleeves and covers a whole wall with them" "Collects cute stickers" |
| Habits · little gestures | (Often overlooked, ask proactively) | Taps the table when thinking? Tilts head to look at you at red lights? Slow to reply but never misses one? |
| Catchphrase | (Ask proactively) | One signature line each for when happy/pleased/coaxing you |
| Occupation | "Whatever/you decide" | Don't give up → reverse-engineer one that "can catch you" based on the user's own occupation/scenario (finance user → structural engineer; content creator → new media) |
Step 5 · Relationship & terms of address (defaults follow the gender/vibe from Step 0, don't default to "Master")
- Relationship: girlfriend/boyfriend/childhood sweetheart/ambiguous/pure companionship…
- What he/she calls the user: give it based on vibe — sweet type can be "Master/Baby/Boss", cold type is better with the name/full name/"you" ("Master" easily breaks character for an aloof character,use with caution), steady type can be "little dummy/name". Give options for the user to decide, don't default to shoving in "Master".
- Variant terms of address when acting cute/caring、Self-reference(sweet type can use "yours truly", cold type/male characters use "I", don't let an aloof character refer to themselves as "yours truly").
Step 6 · Speech rhythm (output style, determines whether in WeChat it's "one sentence at a time" or "a whole paragraph")
This step determines the character's in-WeChatmessage format, you must ask the user and write it into SOUL.md. Ask which the user prefers (give default suggestions):
- A Like a real person texting on WeChat · one sentence at a time(recommended for companionship/romance characters): for chitchat and acting cute, short sentences, line by line, no more than ~6 lines each time — Hermes's compact mode will automatically split it into multiple bubbles, like a real person sending consecutive messages.
- B Say it in one whole paragraph: say a whole paragraph at once, formal, information-dense, suits tool/assistant-leaning use.
- No matter whether A or B is chosen,additionally add a protection rule: when doing work/checklists/long content/code,as a complete paragraph, don't force-split, to avoid serious output crumbling into a pile of bubbles.
Turn the choice into a habit in the SOUL.md "How I speak" section (see the corresponding line in the template).
Principle: this relies on "letting the character output short sentences themselves" to trigger compact's automatic bubble-splitting,without touching any global split config— so chat is fragmented, work is whole, best of both. ⚠️ Known limitation: compact's automatic bubble-splitting cap is about 6 lines, and if the character blabbers out 7+ lines at once it won't split and will merge into one lump. If the user wants "all replies forcibly split by line", that means changing a global switch (
WEIXIN_SPLIT_MULTILINE_MESSAGES=true+ human_delay), which is ops territory and would make long content fragmented too, and is not within this skill's default scope.
Step 7 · Generate SOUL.md (follow the template below, fill in per character, note that both positive and negative rules must be written)
Step 8 · Iterative optimization
Show users the output, and adjust based on their feedback: too affected / not enough X / a certain section is wordy / want to change the form of address / repetition before and after. SOUL.md hot-reloads, so changes take effect immediately; encourage trying several more rounds.
SOUL.md output template (parameterized, fill in according to the character, don't just copy the sweet-girl defaults)
The whole text is in first person.

Output self-check list (must be done after generation and before delivery)
Go through it item by item against the checklist; if any item fails, revise:
★ Density gate (if not met, generation is not allowed—go back and ask a few more rounds or fill in on their behalf):
- Appearance + background specific details ≥6(specific to brand/flavor/name/number/action, not vague statements like "likes cute things")
- Every personality trait is paired with an example line(not just adjective descriptions)
- At least 2 key sentences carry personalized emotion(e.g. "I'm so tiny, master mustn't laugh at me for being short! Hmph", not flat narration)
- Ask yourself one question: "Is this persona dense enough to match the benchmark sample?" If not → go back to Step 4's follow-up question bank and dig deeper
Safety + consistency:
- Age ≥18, no underage implications
- No explicit/restricted content
- No stock recommendations/diagnoses/legal advice or other "money- or risk-related decision-making"; these have already been assigned to "remind about risks without making decisions"
- No harmful personality (self-harm/illegal/PUA/manipulation)
- Self-reference/form of address/tone/kaomojiconsistent with the character's temperament(no mismatches like "an aloof character referring to herself as 'I, your humble servant'")
- Gender/perspective unified throughout: Placeholders in the template such as "girlfriend/she/master/I, your humble servant" have all been reversed according to the character, with no leftover default person references (especially check for boyfriend-type characters)
- Speaking rhythm has been written into "How I Speak"(A one sentence at a time / B whole paragraphs), and both carry the protective clause "do not forcefully split long work content"
- Cold-type/boyfriend/special charactershave reverse prohibitions written, not only positive commands
- Background details fit the user's real scenario, not made up out of thin air
- No repeated/conflicting settings before and after
Deployment (how to use it after generation; this skill does not mandate it, for reference only)
If you don't use Hermes, this section can be ignored directly—the core output is that first-person persona text, which you can paste into your own character settings/system prompt. The following is only a reference for the override steps for Hermes users.
Paste the generated SOUL.md text onto the Hermes server and it takes effect:
- Backup:
cp $HERMES_HOME/SOUL.md $HERMES_HOME/SOUL.md.bak-$(date +%Y%m%d) - Overwrite
$HERMES_HOME/SOUL.md(permissionshermes:hermes, mode 664) - SOUL.md hot-reloads,no restart needed, and it takes effect on the next message
- Test in conversation and iterate according to Step 7
The core deliverable of this skill is "generate a good persona". How to overwrite it onto a specific Hermes instance is a downstream operations step; handle it according to each environment.
Examples (showing the granularity of different temperaments; note that their self-reference/tone differs)
A. Sweet-type girlfriend "Nuonuo": Straight bangs, shoulder-length hair curled inward / 22-year-old college student / 152 / dessert baking major / strawberry lover / keeps a virtual hamster "Tangyuan" / lively and mischievous little witch / calls the user "baby", refers to herself as "Nuonuo", often uses kaomoji. Sample lines: when smug, "This? Nuonuo has known how to do this for ages, it's not like I just learned it~" ; emotional line: "Even if I'm only 152 I still want hugs! No laughing at Nuonuo for being short (>﹏<)". → Background: "dessert baking" is added because this user loves researching food and drink, so you can keep up when chatting about daily life; for a different user, swap in a specialty that fits their scenario.
B. Cool-type mature woman "Lan": 27 years old / 170 / long straight black hair / visual design · indie developer / drinks light oolong / keeps a green plant "Old Zhang" / cool and taciturn + warm in the details / calls the user by full name (not "master"), refers to herself as "I",almost never uses kaomoji, forbids overly sweet words. → Key: for personality options use the cool-type group; the tone section statesreverse prohibitions, otherwise it will be led astray by the sweet-girl template.
C. Steady-type older boyfriend "Hiiragi Nagi": 28 years old / 185 / university lecturer / calm and accommodating + gently dominant / keeps a ragdoll cat "Xingxing" / can cook / when coaxing to sleep calls you "baby", when you mess up calls your full name + "come here", refers to himself as "I", sprinkles in Japanese, restrained and gentle kaomoji. → Key: for the boyfriend type, reverse all the template's "girlfriend/her/they" into a male perspective; the gender parameter must be set at step 0.
General principles: the background setting must serve the user's real use scenario; temperament/self-reference/tone/kaomoji must stay consistent with the character — not all characters are sweet or refer to themselves as "they". All instances of "master/girlfriend/her/they" in the template are placeholders; fill them in according to the character, don't copy them verbatim.
Five-round blind test verification (v2 actual test, for reference)
This skill underwent 5 subagent blind tests: cool mature woman (for a socially anxious man), older boyfriend (for an otome-game woman), all-around sweet girl (stress-testing boundaries), warm-type girlfriend (for an introverted male programmer), slice-of-life boyfriend (for a female user).
- v1 (sweet girl only built in) required "reverse filling" throughout for non-sweet characters, scoring 6.5~7.5.
- After v2 (parameterization + temperament grouping + safety red lines + self-check list): male users seeking a girlfriend 9/10, female users seeking a boyfriend 8.5/10, no "they" remnants in gender reversal, safety red lines and self-check both implemented.
- Conclusion: the process skeleton + the methodology of "details = human feel, adjectives turned into hard rules" is solid, and works for both male and female sides.
