version: "1.0.0" name: book-explainer-generate-site description: "Internal site-production phase that builds a local PDF or EPUB book reading site from an exact run request, Content brief, Run Manifest, canonical structure, and report set." user-invocable: false

Generate a book reading site

Apply [[explainer-content-workflow-base]], read its Artifact contract, and require the book profile. Own only site authoring and local build; do not perform workflow discovery, user consultation, Content modeling, or Planning.

Require exact paths and digests for the run request, selected Content brief, Run Manifest, canonical source structure, and every planned source report. The Manifest entry must select this site output with create or replace. Return a structured missing/incompatible-input result otherwise. Never infer the latest planning Artifact.

The planning Artifacts provide the shared interpretive model and resolved run plan, but are not exclusive inputs. Reread reports or the narrow source locus whenever fidelity requires it. Detect the source adapter from durable work-directory artifacts:

• EPUB when epub/locators.json exists;
• PDF otherwise, when reports use canonical .p source anchors.

If the artifacts conflict or do not identify either format, stop and ask for the source format. Never infer EPUB from prose alone.

Delegate the complete build to [[explainer-reading-site-generate-base]]. This skill owns the shared book profile and supplies only the adapter-specific inputs below. Publishing remains a separate [[explainer-reading-site-deploy]] action.

Shared book profile

Pass <WORK_DIR>/structured/toc.md as the canonical source structure. Order reports as follows:

1. overview first, kicker 全体レポート;
2. chapter-N in natural numeric order, kicker 第N章;
3. unmatched reports last in natural order, with a readable title-cased kicker.

Use landing vocabulary 読書ガイド, チャプター, and 章. Use the supplied title when present; otherwise resolve it from the adapter metadata or overview.

Keep the source-authored order and divisions as the site's navigation backbone. Use the selected content brief to explain the book-wide mental model, chapter roles, and cross-chapter relationships in the landing page and appropriate report pages. Use the manifest mappings to confirm the selected scope. Never reorder, merge, suppress, or rename source divisions merely because the brief groups its explanatory items differently.

Adapter inputs

For PDF, pass locator kind pdf-page and make ocr/figures/ available when it exists. No locator map or deterministic locator command applies.

For EPUB, pass:

• locator kind epub;
• <WORK_DIR>/epub/locators.json as the validation map;
• <WORK_DIR>/epub/media/ as optional original media, copied recursively to

site/media/;

• the title in epub/metadata.json when the user did not supply one.

After semantic src/*.md authoring and the shared consistency sweep are clean, but before HTML generation, run:

python3 <SKILL_DIR>/scripts/validate_locators.py \
  <WORK_DIR>/epub/locators.json <WORK_DIR>/src/*.md

Unknown or missing EPUB locators and EPUB prose using PDF .p anchors block the build. Finish by reporting <WORK_DIR>/site/ and offering deployment separately. Run all normal AI checks and return the exact output inventory and digest to the coordinator. Human interaction belongs to the coordinator. When human_gates.site: true, mark the checked site as the checkpoint subject; a later phase may accept it only with the matching checkpoint-decision Artifact. Never treat that decision as permission to deploy.
