Recipe: a production-grade dating character

A complete, copy-paste body that fills every authoring block, plus the validation traps that bite.

This page is a single, copy-paste-ready POST /v1/characters body for a dating character that fills every authoring block LoreOS reads — profile (with a north-star aspiration), voice samples, greeting, onboarding, direction, life template, story engine with supporting cast, world seeds, arc seeds, relationship seed, emotion baseline, affordance_schema, and behavioral_thresholds. Every field below is validated against the typed authoring contract — there are no invented keys.

If you only want the field-by-field reference, read Character authoring. This page is the worked example plus a valid-vs-invalid section for the handful of fields that produce a real 422.

Send this body to POST /v1/characters/validate first (a dry run — same validation, no character created). When it comes back clean, the real POST /v1/characters is guaranteed to validate. See Validate before create.

What “ready” means for this body

The create/get response carries authoring_readiness. This body fills all thirteen scored checks (profile.visible_bio, profile.visible_interests, profile.identity_anchors, voice_samples >= 3, greeting, onboarding, character_direction, life_template, story_engine, world_model_seed, arc_seeds, relationship_seed, emotion_baseline), so:

1{
2 "authoring_quality_score": 100,
3 "missing_high_impact_fields": []
4}

This body sets the north-star keys (aspiration, life_direction, drama_intensity, concreteness_floor, arc_appetite, supporting_cast) inside profile, and that is fully recognized: the readiness scorer knows the north-star keys, so they do not trip a warning. With the score high and zero warnings, this body returns status: "ready".

status is only "ready" when the score is high and there are no warnings. The one warning to watch for here is profile_unknown_keys, which now fires only on a genuinely unknown key — a typo like visible_intrests instead of visible_interests, which is silently preserved (via extra="allow") but never read at runtime. Treat profile_unknown_keys as a prompt to look: it means a profile key you wrote isn’t one the engine knows, so fix the spelling and re-validate.

The leverage each block adds, and the runtime behaviors it drives, are documented in Character authoring and Story Room and life. To turn this into a runnable end-to-end project, see Deploy a Node chat.

Validate before create

POST /v1/characters/validate is a dry run: it runs the exact same validation and readiness scoring as POST /v1/characters (north-star shape, affordance schema, every field range) but never persists anything. A clean validate guarantees a clean create, so an agent can iterate to missing_high_impact_fields: [] before spending a create.

$curl -sS https://api.loreos.app/v1/characters/validate \

validate uses the same 422 codes as create. If it fails, the response body is the standard error envelope — fix the field it names and re-validate:

1{ "detail": { "code": "invalid_character", "message": "...", "fix": "..." } }

Valid vs. invalid: the fields that produce a 422

Most authoring fields are forgiving. These six are where real requests fail, with the exact error each one returns. The error body is always { "detail": { "code": "...", "message": "...", "fix": "..." } }; the loc/msg shown is from the underlying validation error quoted back in message.

forbidden_style — list of objects, never list of strings

This is the single most common 422. forbidden_style is a list[dict] (each entry is an object describing one style rule). Passing a list of plain strings fails.

1{
2 "forbidden_style": [
3 { "pattern_description": "generic cheerful-assistant cadence", "anchor_tier": "T1" },
4 { "pattern_description": "love-bombing in the first few exchanges", "anchor_tier": "T1" }
5 ]
6}
error
loc: ("forbidden_style", 0)
type: dict_type
msg: Input should be a valid dictionary

The keys the runtime actually reads from each object are:

  • expression — an exact literal phrase to avoid, or

  • pattern_description — a description of the phrasing/cadence to avoid.

    The engine uses expression if present, otherwise pattern_description — so each entry needs at least one of the two to carry any meaning. An entry with neither is silently dropped (it never reaches the critic), so it won’t 422 but also won’t do anything.

  • anchor_tier"T1""T3", strongest first; defaults to "T1" when omitted.

The object is otherwise free-form: extra keys are preserved on the record but are not read. In particular, an object like { "rule": "...", "severity": "hard" } validates fine (it’s a dict) yet has no effect, because the runtime reads expression/pattern_description, not rule/severity. Use pattern_description (or expression). handoff_triggers has the same list[dict] shape and the same “must be an object” trap.

Today forbidden_style is strictly list[dict], so a list of plain strings is a 422. Accepting a bare string as shorthand for { "pattern_description": "<the string>" } would be a nice ergonomic improvement, but it is a server-side change and is not supported yet — for now, always send objects.

world_model_seed — typed entries (or the legacy domain/claim_text pair)

Each seed is either a typed entry (type + name + description) or a legacy claim (domain + claim_text). A typed entry auto-derives the legacy domain/claim_text for you; a seed that supplies neither a usable name/description nor a claim_text is silently dropped at session time (never speakable), so the trap here is a seed that does nothing, not a hard 422.

1{
2 "world_model_seed": [
3 {
4 "id": "the-cafe",
5 "type": "location",
6 "name": "Sora's cafe",
7 "description": "a tiny eight-seat cafe in Mapo where Mina bakes",
8 "visibility": "character_known",
9 "salience": 0.9
10 }
11 ]
12}

type is one of location | person | object | organization | routine | constraint | claim (default claim). visibility is character_known | session_visible | developer_only (default character_known) — developer_only seeds are never speakable. salience is 0..1. Prefer the typed form: it is self-documenting and the engine fills the legacy fields.

arc_seedsallowed_movements is a fixed enum

allowed_movements only accepts plant, reinforce, partial_payoff, defer, abandon. Anything else (escalate, resolve, climax, …) is a 422.

1{
2 "arc_seeds": [
3 {
4 "title": "The dessert counter",
5 "arc_question": "Can Mina take a real step toward her own place this season?",
6 "allowed_movements": ["plant", "reinforce", "partial_payoff", "defer"]
7 }
8 ]
9}
error
loc: ("arc_seeds", 0, "allowed_movements", 0)
msg: Input should be 'plant', 'reinforce', 'partial_payoff', 'defer' or 'abandon'

title and arc_question are both required on every arc seed. Arc seeds are soft directions, not a script — keep forbidden_outcomes and user_agency_points so the user can intervene.

onboarding — both question and answer are required

Each onboarding entry needs a non-empty question and a non-empty answer. Sending one without the other is a 422.

1{
2 "onboarding": [
3 {
4 "question": "What does Mina do for a living?",
5 "answer": "She's a pastry cook at a small Mapo cafe, saving toward her own dessert counter.",
6 "allowed_uses": ["character_self_knowledge", "planning_only"]
7 }
8 ]
9}
error
loc: ("onboarding", 0, "answer")
msg: Field required

privacy_tier (default "private_knowledge") and allowed_uses are optional. Onboarding is private self-knowledge the character can use for planning — it is not spoken verbatim.

behavioral_thresholds0..1 floats and 0..N ints, and 0 means OFF

Image and proactive knobs are bounded. A float over 1.0 (or an int over its ceiling) is a 422. Just as important: the image knobs default to 0, which means images are OFF — leaving them at 0 is valid but the character will never send a selfie.

1{
2 "behavioral_thresholds": {
3 "image_proactivity": 0.4,
4 "daily_image_cap": 2,
5 "selfie_comfort": 0.5
6 }
7}
error
loc: ("image_proactivity",)
msg: Input should be less than or equal to 1

To actually get selfies you need both image_proactivity/selfie_comfort > 0 and daily_image_cap > 0 and an uploaded identity image — see Visual identity.

The recipe above authors profile.identity_anchors as a list[str] (it doubles as voice/persona anchors). The contract accepts both shapes — identity_anchors is typed list[str] | dict, so a dict is settable straight through POST /v1/characters with no 422 — but the image pipeline reads only the dict form of visual keys. So if you turn images on (as this recipe does), author profile.identity_anchors as an object (visual_summary / hair / style_constants …) instead; a dict satisfies authoring readiness and selfie generation, while a list satisfies readiness but leaves the image pipeline without a visual reference. Full explanation: Visual identity → the dict requirement.

daily_image_cap is 0..20, daily_initiate_cap is 0..50; cold_initiate_enabled defaults to false and session_resume_enabled defaults to true. The full knob list is in Character authoring.

affordance_schema — only dating and tutor are presets

affordance_schema declares the relationship the engine tracks. The only built-in preset names are dating (the default) and tutor. There is no companion preset — any other domain must be a full inline schema. An unknown preset name is a 422.

1{ "affordance_schema": "dating" }
error
code: invalid_affordance_schema
message: affordance_schema failed validation: unknown affordance preset 'companion' (known: ['dating', 'tutor'])

Each inline dimension needs a key (^[a-z][a-z0-9_]*$) and a prompt_rendering_name; default (in range, default 0.3), range (default [0, 1]), and lower_is_open (default false) are optional, and dimension keys must be unique. GET /v1/characters/{slug}/runtime-preview shows the declared dimension names the engine ends up tracking. See Character authoring.

Checklist before you ship this character

  • validate returns valid: true, missing_high_impact_fields: [], and (for this body) status: "ready" with no warnings.
  • No profile_unknown_keys warning. The north-star keys (aspiration, life_direction, …) are recognized and don’t warn; this warning now fires only on a genuinely unknown key — a typo like visible_intrests. If you see it, fix the spelling.
  • forbidden_style and handoff_triggers are lists of objects, not strings.
  • Every arc_seeds[].allowed_movements value is one of the five allowed movements, and each arc seed has a title and arc_question.
  • Each onboarding entry has both question and answer.
  • behavioral_thresholds floats are 0..1 and ints are within range; image knobs are > 0 only if you also uploaded an identity image.
  • affordance_schema is dating/tutor or a full inline schema with unique dimension keys.
