Peer to `node-pack-manifest.schema.json` (RFC 0003) and `workflow-chain-pack-manifest.schema.json` (RFC 0013); disjoint from both via the `kind` discriminator. See `spec/v1/prompts.md` §\"Discovery & distribution\" for the canonical contract and RFC 0028 §B for the rationale.\n\nPrompt packs distribute curated PromptTemplate collections via the same signed-tarball + Ed25519 + SRI pipeline that already serves node and workflow-chain packs. When a host installs a prompt pack and advertises `capabilities.prompts.packsSupported: true`, the templates appear in `GET /v1/prompts` with `meta.source: \"pack\"` + `meta.packName` + `meta.packVersion`.",
