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](./character-authoring). This page is the worked example plus a **valid-vs-invalid** section for the handful of fields that produce a real `422`. > **Tip** > > 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.

For a schema/voice smoke test, change `background_features.auto_activate` to `false`; no schedule will be registered, and you can activate selected features later. ### What "ready" means for this body The create/get response carries `authoring_readiness`. This body fills **all fourteen scored checks** (`profile.visible_bio`, `profile.visible_interests`, `profile.identity_anchors`, `voice_samples >= 3`, `example_dialogues >= 2`, `greeting`, `onboarding`, `character_direction`, `life_template`, `story_engine`, `world_model_seed`, `arc_seeds`, `relationship_seed`, `emotion_baseline`), so: ```json { "authoring_quality_score": 100, "missing_high_impact_fields": [] } ``` > **Note** > > 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](./character-authoring) and [Story Room and life](./story-room-and-life). To turn this into a runnable end-to-end project, see [Deploy a Node chat](./deploy-node-chat-tutorial). ## 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. ```bash curl -sS https://api.loreos.app/v1/characters/validate \ -H "Authorization: Bearer $LOREOS_KEY" \ -H "Content-Type: application/json" \ -d @character.json ``` ```json { "schema_version": "...", "data": { "valid": true, "slug": "mina-cafe", "authoring_readiness": { "status": "ready", "authoring_quality_score": 100, "missing_high_impact_fields": [], "warnings": [], "next_authoring_actions": [] } }, "next_actions": [ { "command": "POST /v1/characters (same body) — validation passed; safe to create", "description": "..." } ] } ``` `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: ```json { "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. **`✅ valid — list of objects`** ```json title="✅ valid — list of objects" { "forbidden_style": [ { "pattern_description": "generic cheerful-assistant cadence", "anchor_tier": "T1" }, { "pattern_description": "love-bombing in the first few exchanges", "anchor_tier": "T1" } ] } ``` **`❌ invalid — list of strings`** ```json title="❌ invalid — list of strings" { "forbidden_style": ["no emojis", "don't be a generic assistant"] } ``` **`error`** ```text title="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. > **Note** > > 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": "" }` 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`. **`✅ valid — typed entry`** ```json title="✅ valid — typed entry" { "world_model_seed": [ { "id": "the-cafe", "type": "location", "name": "Sora's cafe", "description": "a tiny eight-seat cafe in Mapo where Mina bakes", "visibility": "character_known", "salience": 0.9 } ] } ``` **`✅ valid — legacy claim`** ```json title="✅ valid — legacy claim" { "world_model_seed": [ { "domain": "location", "claim_text": "Mina bakes at a tiny eight-seat cafe in Mapo." } ] } ``` **`❌ inert — neither typed body nor claim_text`** ```json title="❌ inert — neither typed body nor claim_text" { "world_model_seed": [ { "type": "location", "salience": 0.9 } ] } ``` `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_seeds` — `allowed_movements` is a fixed enum `allowed_movements` only accepts `plant`, `reinforce`, `partial_payoff`, `defer`, `abandon`. Anything else (`escalate`, `resolve`, `climax`, …) is a `422`. **`✅ valid`** ```json title="✅ valid" { "arc_seeds": [ { "title": "The dessert counter", "arc_question": "Can Mina take a real step toward her own place this season?", "allowed_movements": ["plant", "reinforce", "partial_payoff", "defer"] } ] } ``` **`❌ invalid — 'escalate' is not a movement`** ```json title="❌ invalid — 'escalate' is not a movement" { "arc_seeds": [ { "title": "The dessert counter", "arc_question": "Can Mina take a real step toward her own place this season?", "allowed_movements": ["plant", "escalate"] } ] } ``` **`error`** ```text title="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`. **`✅ valid`** ```json title="✅ valid" { "onboarding": [ { "question": "What does Mina do for a living?", "answer": "She's a pastry cook at a small Mapo cafe, saving toward her own dessert counter.", "allowed_uses": ["character_self_knowledge", "planning_only"] } ] } ``` **`❌ invalid — answer missing`** ```json title="❌ invalid — answer missing" { "onboarding": [ { "question": "What does Mina do for a living?" } ] } ``` **`error`** ```text title="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_thresholds` — `0..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. **`✅ valid — images on`** ```json title="✅ valid — images on" { "behavioral_thresholds": { "image_proactivity": 0.4, "daily_image_cap": 2, "selfie_comfort": 0.5 } } ``` **`✅ valid — images off (the default)`** ```json title="✅ valid — images off (the default)" { "behavioral_thresholds": { "image_proactivity": 0, "daily_image_cap": 0, "selfie_comfort": 0 } } ``` **`❌ invalid — out of range`** ```json title="❌ invalid — out of range" { "behavioral_thresholds": { "image_proactivity": 1.5 } } ``` **`error`** ```text title="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](./visual-identity-spec). > **Warning** > > 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](./visual-identity-spec#visual-readiness-and-the-exact-pass-or-fail-rules). `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](./character-authoring#behavioral-thresholds-enabling-selfies-and-proactive-messages). ### `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`. **`✅ valid — a preset`** ```json title="✅ valid — a preset" { "affordance_schema": "dating" } ``` **`✅ valid — a full inline schema (e.g. a 'companion' domain)`** ```json title="✅ valid — a full inline schema (e.g. a 'companion' domain)" { "affordance_schema": { "schema_version": "companion.v1", "domain": "companion", "dimensions": [ { "key": "warmth", "prompt_rendering_name": "warmth", "default": 0.3 }, { "key": "trust_level", "prompt_rendering_name": "trust", "default": 0.2 }, { "key": "boundary_level", "prompt_rendering_name": "boundary", "default": 0.5, "lower_is_open": true } ] } } ``` **`❌ invalid — 'companion' is not a preset`** ```json title="❌ invalid — 'companion' is not a preset" { "affordance_schema": "companion" } ``` **`error`** ```text title="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](./character-authoring#affordance-schema-the-relational-domain). ## 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.
