platform-specs-and-validation

The cross-cutting publish-readiness skill — make a post correct on every target (required fields, media rules, limits) and run the validate-before-publish loop. It's the keystone the format skills point to. The agent maps fields + fixes spec violations + validates; WoopSocial validates and publishes; content craft and human-judgment calls stay elsewhere.

The POV: publish-ready, atomically, the first time

WoopSocial validates and publishes atomically — POST /posts checks every target together, and if any one fails, nothing is created. There's no update endpoint, so a post that publishes wrong can't be patched (edit = delete + recreate). That makes getting every target's fields right before publish the whole game: the right postType, the required per-platform fields, the media rules, and account-specific values (Pinterest board, TikTok privacy) resolved from platform-inputs — then POST /posts/validate to catch what's left. This skill is where the format skills come to make sure it will actually go through.

The framework: CHECK

(Depth: references/the-check-framework.md.)

• C — Collect the targets + project: list the social accounts; confirm they're in the same project; note each platform's field set.
• H — Hydrate per-platform required fields: fill each target's required fields (FB/IG postType; TikTok's eight; YouTube title+privacy; Pinterest pinterestBoardId); resolve account values from GET /social-accounts/{id}/platform-inputs.
• E — Enforce media + content rules: FB no image+video mix; IG Stories need media; Pinterest single media; TikTok PHOTO/VIDEO field applicability; use contentOverride or separate posts where fan-out conflicts; respect text limits.
• C — Confirm truthful declarations: isBrandedContent/isYourBrand/madeForKids are truthful declarations, not validation knobs — never flip them to clear an error; these stay with the person.
• K — Knock it through validation: POST /posts/validate → fix all errors, review warnings → create (atomic). No update → delete + recreate (only while NOT_STARTED).

The spec (ground truth — verify-quarterly)

Per-platform postType enums + required-field matrices + media rules + the platform-inputs discovery endpoint + lifecycle facts (atomic create, no update, delivery status, schedule types): references/woopsocial-publish-spec.md. The validate-then-create loop, the full ValidationField code table + CreatePostErrorCode list + worked examples: references/validation-reference-and-recipes.md. (The live OpenAPI spec / tools/integrations/woopsocial.md are the source of truth; enums and limits move.)

Honest scope (never violate)

• This skill ensures publish-READINESS (fields/media/spec correct + validated) — it doesn't write or improve the creative (the format/content skills do) and can't guarantee performance.
• WoopSocial validates + publishes atomically; one failing target fails the whole post. No update → delete + recreate (only while NOT_STARTED).
• Disclosure/compliance declarations stay truthful (isBrandedContent/isYourBrand/madeForKids) — never flipped to pass validation; privacy intent + disclosure truthfulness stay with the person.
• Resolve account values (board, privacy) from platform-inputs — don't guess. Never fabricate metrics — native analytics only. (Scope, distinctions + connections: references/scope-and-connections.md.)

Distinct from its siblings (route correctly)

platform-specs-and-validation (this) = the cross-platform field/media/validation layer that makes a post publish-ready on every target · the per-platform format skills (tiktok-photo-mode, tiktok-video-publishing, threads-post, youtube-publishing-and-metadata, carousel-writer, …) = craft one platform's content and point here for validation · scheduling-and-queue = timing/cadence, not correctness · tools/integrations/woopsocial.md = the shared integration guide this applies post-level.

Where this connects

Receives from: every format skill (crafted content + chosen postType) and content-calendar (the plan). Resolves with: GET /social-accounts/{id}/platform-inputs (boards, privacy options) + the integration guide. Hands to: scheduling-and-queue → WoopSocial (POST /posts after isValid), then webhooks/delivery status for confirmation. Supports: cross-platform-repurposing (per-target contentOverride), analytics-and-reporting (native delivery readout), experimentation (valid variants). Content craft + truthful declarations stay with the format skills + the person.

Definition of done

Every target collected and confirmed in one project; each target's required fields hydrated (postType / privacy / board / disclosure / title as applicable) with account-specific values resolved from platform-inputs; media + content rules enforced (no FB mix, IG-Story media, single Pinterest media, TikTok field applicability) with contentOverride or separate posts where fan-out conflicts; disclosure/madeForKids declarations left truthful (never flipped to pass); POST /posts/validate run with all errors resolved and warnings reviewed before an atomic create; edits handled via delete+recreate, nothing fabricated and no promised performance; correctly distinguished from the per-platform format skills and scheduling-and-queue.
