zuvo:content-expand — Expand & Optimize Articles

Take an existing article, research the topic, add what's missing, and optimize the result — all in one pass. Same quality standards as zuvo:write-article.

Scope: Expand thin content, add missing sections, research and integrate new facts, optimize prose quality, update SEO/schema. Out of scope: Encoding/markdown fixes (zuvo:content-audit + content-fix), writing from scratch (zuvo:write-article), CMS API, PDF/Word.

Mandatory File Loading

Phase 0 (always):

1. ../../shared/includes/env-compat.md -- Agent dispatch
2. ../../shared/includes/run-logger.md -- Run logging
3. ../../shared/includes/banned-vocabulary/core.md -- Shared anti-slop rules, tone matrix, G12, fallback behavior
4. ../../shared/includes/humanization-rules.md -- Writing constraints + voice matching
5. ../../shared/includes/domain-profile-registry.md -- 17 niche profiles
6. ../../shared/includes/seo-page-profile-registry.md -- SEO profiles
7. ../../shared/includes/no-pause-protocol.md -- HARD: no mid-loop pauses (batch/multi-section)

Lazy-loaded (Phase 2 only):

7. ../../shared/includes/prose-quality-registry.md -- PQ1-PQ18 (scoring)
8. ../../shared/includes/adversarial-loop-docs.md -- Cross-model review (end of Phase 2)
9. ../../shared/includes/article-output-schema.md -- JSON output
10. ../../shared/includes/retrospective.md -- RETRO PROTOCOL

Print CORE FILES LOADED: for items 1-6. After language detection, print LANGUAGE FILE: with the resolved banned-vocabulary language file and whether English fallback was used. Lazy items loaded inline when needed.

Safety Gates

GATE 1 — File Type

.md, .mdx supported. .html tolerated (tag-stripped, WARNING). Binary → STOP.

GATE 2 — Dirty File Check

git status --porcelain -- <file>. Uncommitted changes → STOP. Require commit or stash. --dry-run mode: proceed with WARNING (no file mutation).

GATE 3 — Write Scope

Allowed: input file, <file>.content-expand-backup, zuvo/reports/. FORBIDDEN: everything else.

Arguments

Argument	Behavior
[file]	Required. Path to .md/.mdx file to expand
--dry-run	Show proposed changes without writing. Print before/after diff
--lang <code>	Language override (default: auto-detect)
--tone <value>	casual / technical / formal / marketing (default: auto-detect from existing text)
--site-dir <path>	Content collection root — enables internal link discovery + voice matching
--domain <niche>	Override domain detection (one of 17 niche IDs from domain-profile-registry.md)
--skip-research	Skip web search; expand using existing content + LLM knowledge only
--rewrite	Allow rewriting existing sentences that have concrete defects (factual errors, grammar, outdated info). Without this flag, existing text is never modified.
--light	Skip reporting, backlog, knowledge curation. Just expand and write.

Phase 0 — Read & Score

0.1 Validate + Extract

1. File type validation (GATE 1). Dirty file check (GATE 2).
2. Parse frontmatter. Mark mutable fields (title, description, keywords, author). All others immutable.
3. Extract protected regions: fenced code blocks, MDX components. Store with position markers.
4. Language detection: --lang → frontmatter → content analysis → fallback structural-only.
5. Resolve the active language file from ../../shared/includes/banned-vocabulary/languages/ using the normalized base code. If missing: load en.md and emit WARNING: banned-vocabulary fallback -> en.

0.2 Domain Detection

Cascade: --domain → scan --site-dir articles for niche signals per domain-profile-registry.md → fallback general. YMYL niches emit credentials WARNING.

0.3 Voice Profile

If --site-dir has 3+ blog articles: extract voice profile per humanization-rules.md (rhythm, person, formality). Inconclusive → default rules only.

0.4 Score

Dispatch prose-quality-scorer + structure-analyst agents in parallel per env-compat.md. Score across 6 dimensions (PQ1-PQ17 from prose-quality-registry.md). Short articles get the same scrutiny as long ones — every sentence matters more when there are fewer of them.

Record: before-scores, tier, weak sections, thin sections (<100 words), missing elements per niche profile.

0.5 Internal Link Discovery

If --site-dir provided: scan the content collection (Glob *.md + *.mdx), read titles/descriptions of 10-20 articles, identify 5 most related by topic overlap. These become internal link candidates for Phase 2.

Print:

SETUP: [file] | [lang] | [tone] | Domain: [niche] | Voice: [matched|default]
SCORE: [composite]/100 ([tier]) | Weak: [N sections] | Thin: [N sections]
LINKS: [N candidates found | no site-dir]

---

Phase 1 — Research

Skip if --skip-research set. Print: "Research skipped. Expanding from existing content + LLM knowledge."

1.1 Topic extraction

From article content + frontmatter, identify: primary topic, subtopics covered, subtopics missing (from Phase 0 scoring).

1.2 Web search

Perform 2-4 targeted web searches about the topic — NOT competitor analysis, but factual research for expansion:

• Facts, statistics, recent developments about the topic
• Specific details the article is missing (from Phase 0 thin-section analysis)
• Named sources, dates, version numbers for entity grounding

1.3 Fact sheet

Assemble research into a structured fact sheet (same format as write-article topic-researcher output). Each fact has source attribution + year. Tag conflicts as [CONFLICT].

If web search unavailable: note research_limited: true, proceed with LLM knowledge only (clearly marked).

---

Phase 2 — Expand + Optimize

This is the core phase. Expand THEN optimize in one pass — no separate faz.

2.1 Backup

Copy original to <file>.content-expand-backup. All work on temp copy. --dry-run: skip backup, work in memory only.

2.2 Expand (PRESERVE ORIGINAL TEXT)

DEFAULT: Do not rewrite existing text. Rewriting human prose with AI prose triggers detection on the entire article. Expand by ADDING content around what exists.

What you CAN always do:

• Add new paragraphs between or after existing ones
• Add new H2/H3 sections for missing subtopics
• Add intro/conclusion if missing

What you CANNOT do without --rewrite:

• Rephrase existing sentences
• Merge or reorder existing paragraphs
• Change existing word choices or headings

With --rewrite: Rewrites are allowed ONLY for sentences with a concrete defect: factual error, grammatical mistake, nonsensical claim, or outdated information. Each rewrite must state the reason (e.g., "Fixed: claimed population is 5M, actual is 8.3M per 2025 census"). Style preferences ("sounds better") are NOT a valid reason.

For ALL new content, apply humanization-rules.md constraints:

• Sentence variation (fragments + long), contractions, parenthetical asides
• Entity grounding (specific versions, dates, names from research)
• Voice matching if profile available — match the existing article's voice, not your default
• No throat-clearing (G12), BLUF per section (G9), max 300 words/section (G6)
• Stats and volatile practical facts must remain traceable to the fact sheet (G11)
• Do not build paragraph rhythm around repeated source lead-ins such as Według X (2025)
• Use a hard source-name budget: the same full institution/source name should appear no more than once per section and no more than 3 times in the whole article body, excluding a compact ## Źródła section
• Use (odczyt: miesiąc rok) only for volatile practical facts, not for stable historical description
• Do not append a process-heavy research appendix such as Źródła wykorzystane przy aktualizacji
• End public articles with a compact ## Źródła section unless the host project explicitly forbids visible sources
• In ## Źródła, keep 3-6 grouped bullets max: source title + link only
• Group repeated institutions into one bullet whenever possible, e.g. - **APSARA National Authority:** [Temple page](...), [Restoration update](...)
• Do not add filler closers like ## Na koniec if they only restate the article
• Prefer practical expansion blocks (specific H2s, lists, route notes, local comparisons, FAQ at the end) over replacing the opening with smoother narrative prose
• For practical/service-intent articles, add or preserve a short ## W skrócie block immediately after the italic lead and before the first image or H2. Keep 3-5 bullets max.

Use these exact output shapes when applicable:

## W skrócie
- [Najważniejsza decyzja / odpowiedź]
- [Najważniejszy wymóg / koszt / limit]
- [Najważniejsza opcja / wyjątek]
- [Najważniejszy warunek praktyczny]

## Źródła
- **[Instytucja / grupa źródeł]:** [Tytuł 1](...), [Tytuł 2](...)
- **[Instytucja / grupa źródeł]:** [Tytuł 3](...)
- **[Instytucja / grupa źródeł]:** [Tytuł 4](...)

2.3 Internal Links

Insert 2-5 contextual internal links from Phase 0 candidates. Validate each via Glob. Unverified → [UNVERIFIED LINK], not auto-inserted.

2.4 SEO + Schema

Read domain-profile-registry.md for niche-appropriate schema:

• Detect existing @type. If specific (Recipe, HowTo, Event) → preserve and merge. If BlogPosting only → upgrade per niche.
• FAQ: if article now has Q&A content + niche allows FAQ → add FAQPage schema.
• Inspect the local content schema/config before mutating frontmatter. Treat the schema as the source of truth for allowed fields.
• OG tags: write og:title, og:description, og:type, og:image only if those fields are clearly accepted by the local schema. If not, inherit layout-level OG behavior and record OG: inherited-from-layout.
• dateModified / modifiedDate / updatedDate: Find the exact modification-date field already accepted by the collection schema (common names: modifiedDate, updatedDate, dateModified, lastmod, updated) and update that field. If no such field exists and schema support is unclear, do not invent modifiedDate; leave frontmatter unchanged and record Date field: unchanged (schema-blocked). Never touch publishDate / date / publishedDate — that's the original publication date.
• Meta title/description: only update if currently MISSING. Never rewrite existing meta that the author wrote.

2.5 Anti-slop Review

Run anti-slop check on expanded content (same as write-article Phase 4):

• Hard/soft banned vocabulary per banned-vocabulary/core.md + active language file + --tone
• G12 anti-patterns (throat-clearing, superlatives, keyword density)
• BLUF compliance (G9), chunkability (G6), citation compliance (G11)
• Dispatch anti-slop-reviewer agent (read ../../skills/write-article/agents/anti-slop-reviewer.md) for all articles regardless of length.

Apply this review to human-facing prose only. Do not count frontmatter keys, schema-only metadata, file paths, URLs, image names, JSON-LD/schema, code, or raw source lists as banned-vocabulary violations unless the task explicitly asks to audit those zones as prose.

Fix all CRITICAL violations. Fix WARNINGs if localized.

2.6 Re-score + Rollback

Score expanded article (same 6 dimensions). If ANY dimension regressed → revert that section's changes. Never deliver a lower composite score.

2.7 Adversarial Review

Load adversarial-loop-docs.md now. Run: adversarial-review --json --mode article --files "<temp-file>" (fallback: --json --mode audit + WARNING). CRITICAL → fix. WARNING → fix if localized. If the script returns status: "timeout" or exits 124, record Adversarial review: skipped (timeout) and continue without blocking the article.

2.8 Replace Original

Protected regions re-inserted. Frontmatter immutable fields preserved. Replace original with expanded temp copy. Delete backup. --dry-run: print diff only, no file changes.

Append via wrapper (REQUIRED). Never >> directly to ~/.zuvo/runs.log — the wrapper is the gate that verifies a retro entry exists for this run. Order: retro bash executed → wrapper invoked → completion claimed.

printf '%b\n' "$RUN_LINE" | ~/.zuvo/append-runlog

Expected stdout: OK: appended to runs.log (retro verified for <skill> on <project>). If exit 2 with RETRO_REQUIRED — go execute the retro bash from retrospective.md first; never bypass with ZUVO_SKIP_RETRO_GATE=1. After the wrapper succeeds, print a Logs: evidence line (tail -1 ~/.zuvo/retros.log, grep -c "^<!-- RETRO -->" ~/.zuvo/retros.md, tail -1 ~/.zuvo/runs.log) before claiming completion. Printing the markdown retro section without executing the bash leaves all three log files empty.

VERDICT: PASS (expanded, no regressions), WARN (research_limited or voice delta MED+), FAIL (adversarial blockers), BLOCKED (dirty file, binary input). NOTES: [file basename] [before]->[after] +[N]words [tier] (max 80 chars).

Reporting (skip with --light)

Unless --light: write report to zuvo/reports/content-expand-YYYY-MM-DD.md. Write JSON per article-output-schema.md. Run knowledge curation per knowledge-curate.md. Persist findings per backlog-protocol.md.

Retrospective (REQUIRED)

Follow retrospective.md. Gate check → structured questions → TSV emit → markdown append.
