## Qué hace

- Fase 1 de solo lectura: puntúa las 5 categorías, cuenta estadísticas sin fuente, revisa jerarquía, schema y frescura, y presenta un plan que espera tu aprobación
- Escaneo editorial de segundo orden: cadencia repetitiva de preguntas en H2, aperturas "Here...", ritmo de tres cláusulas, exceso de matizadores y listas simétricas
- Comprueba canibalización contra el resto del directorio y recomienda fusionar o diferenciar
- Sustituye cada estadística sin fuente por datos tier 1-3 con la provenencia suficiente para verificarla e interpretarla
- Cierra con el contrato de entrega de 5 puertas; si la nota reescrita baja respecto a la original, eso cuenta como P0

## Cuándo usarla

- El usuario dice "reescribe el blog", "optimiza el post", "actualiza el artículo" o "mejora este post"

## Cuándo no

- Solo quieres la auditoría de citas de IA sin tocar el trabajo para Google: el archivo te remite a blog-geo

## Qué la activa

- "Reescribe y optimiza este artículo"
- "Actualiza este post con datos de 2026"

## Antes de instalar

# Blog Rewriter: Optimize Existing Posts

Rewrites and optimizes existing blog posts for dual ranking: Google search
and AI citation platforms. Preserves the author's voice while applying the
6 pillars of optimization.

**Key references:**
- `skills/blog/references/quality-scoring.md` - 5-category scoring (Content 30, SEO 25, E-E-A-T 15, Technical 15, AI Citation 15)
- `skills/blog/references/eeat-signals.md` - Experience, expertise, authority, trust markers
- `skills/blog/references/internal-linking.md` - Linking strategy and anchor text rules
- `skills/blog/references/visual-media.md` - Image sourcing and chart styling
- `skills/blog/references/synthesis-contract.md` - 6 LAWs for re-citation hygiene during rewrite (v1.8.0; cross-skill ref lives in the orchestrator's references dir)
- `skills/blog/references/research-quality.md` - cross-source clustering for replacement-statistic research (v1.8.0)

## Cross-reference

For 21 evidence-led optimization prompts (quality follow-up, CTR audit, schema,
PAA rewording, technical audit, ChatGPT visibility) directly applicable to
rewrite work, see `/blog flow optimize`.

## Workflow

### Phase 1: Audit (Read-Only)

1. **Read the blog post** - Detect format (MDX, markdown, HTML)
2. **Run the quality checklist** against `skills/blog/references/quality-scoring.md`:
   - Count fabricated vs sourced statistics
   - Check answer-first formatting (H2 -> stat in first sentence?)
   - Count images and charts (type diversity?)
   - Review paragraph pacing in context; record length only as a descriptive aid
   - Check heading hierarchy (H1 -> H2 -> H3, no skips?)
   - Check schema presence and validity, prioritizing Article/BlogPosting, Person, Organization, and BreadcrumbList; FAQPage is optional entity markup only
   - Check freshness signals (lastUpdated, dateModified)
   - Assess self-promotion level
   - Evaluate citation tier quality
3. **Advisory editorial style scan**:
   - **Sentence-length variation** - Report it descriptively when rhythm needs
     review. It cannot determine authorship and has no pass/fail threshold.
   - **Known AI phrase scan** - Check for these high-frequency AI phrases:
     - "in today's digital landscape", "it's important to note", "dive into"
     - "game-changer", "navigate the landscape", "revolutionize", "seamlessly"
     - "cutting-edge", "harness the power of", "leverage" (as verb)
     - "delve", "crucial", "elevate", "foster", "landscape" (overused)
     - "multifaceted", "robust", "tapestry", "embark"
     - Full list in `agents/blog-writer.md`
   - **Vocabulary sample** - Report Type-Token Ratio (TTR) descriptively and
     interpret it against text length and specialist terminology.
   - Never estimate AI authorship from TTR, sentence-length variation, punctuation,
     or phrase density. These are advisory project-style observations only.
   - **Second-order structural reflex scan** (v1.8.0) - The first-order checks above
     are vocabulary-level. The second-order pass reviews structural repetition
     that can survive simple wording edits. Run against
     `skills/blog/references/ai-slop-detection.md`. Flag at minimum:
     - Repetitive question-cadence H2s that do not suit reader intent
     - Three or more "Here..." paragraph openers
     - Three-clause sentence rhythm above 50% in any 200-word window
     - More than 2 hedge words ("may," "often," "typically," "generally") in any 20-word span
     - Symmetric-list bloat (list-item word-count SD below 5)
     - More than 2 wrap-up rhetorical questions ("What does this mean for...?")
     - More than half of H2 openers starting with a transition word
     - "The key insight is..." or "What's important here is..." as sentence openers
     - Listicle pre-list intro above 250 words
     - Opening-word repetition: top three first-words above 25% share
     - Paragraph-shape SD below 25 (visual monotony)
     Apply editorial judgment; none of these metrics changes the score or blocks delivery.
4. **Video embed check**:
   - Count existing YouTube embeds in the post
   - If 0 embeds, flag: "No video embeds. Consider adding relevant high-quality YouTube embeds when they add useful context."
   - If present, check: lazy loading? aria-labels? noscript fallback? VideoObject schema?
5. **Cannibalization check**:
   - Identify the post's primary keyword from title, H1, and first paragraph
   - Search the blog directory for other posts targeting the same keyword:
     - Grep headings and meta descriptions across all blog posts
     - Flag any posts with significant keyword overlap
   - If cannibalization found, report:
     - Which posts compete for the same keyword
     - Recommend: **merge** (combine into one stronger post) or **differentiate**
       (shift one post to a related but distinct keyword)
6. **Calculate current score** across 5 categories:
   - Score across 5 categories (Content Quality 30, SEO Optimization 25, E-E-A-T Signals 15, Technical Elements 15, AI Citation Readiness 15)
   - Total: 0-100
7. **Present audit summary** with specific findings, advisory style diagnostics, video status, cannibalization status, and score
8. **Enter plan mode** - Present section-by-section optimization plan

Wait for user approval before proceeding.

### Phase 2: Research

1. **Identify the blog's core topic** from existing content
2. **Find replacement statistics** for any fabricated/unsourced data:
   - Search: `[topic] study 2025 2026 data statistics`
   - Target tier 1-3 sources only
3. **Find images** if post has fewer than 3:
   - Prefer original screenshots, product visuals, diagrams, or data graphics when available
   - For stock, use official provider APIs such as Openverse, Unsplash, Pexels, or Pixabay so license, creator, source URL, and download URL are captured
   - Download approved assets locally, store attribution, and reject `javascript:`, `data:`, and `file:` URLs
   - If `blog-image` is available, offer AI generation for missing or insufficient images and record the selected model ID
4. **Plan charts** if post has fewer than 2:
   - Identify data suitable for visualization
   - Select diverse chart types

### Phase 3: Chart Generation (Built-In)

When the post needs more visual elements, invoke the `blog-chart` sub-skill:

1. Select chart type using the diversity rule (no repeated types per post)
2. Pass: chart type, title, data values, source, platform format
3. Embed the returned SVG directly within a `<figure>` wrapper
4. Target 2-4 charts per 2,000-word post

See `skills/blog/references/visual-media.md` for chart type selection and styling rules.

### Phase 4: Content Rewrite

Apply changes in this order:

#### 4a. Preserve What Works
- Keep the author's voice and unique perspective
- Preserve original insights and first-hand experience
- Keep existing quality images and charts
- Maintain internal links

#### 4b. Fix Frontmatter
- Update `lastUpdated` only when the rewrite materially changes facts, methods, or recommendations
- Keep original `date` unchanged
- Fix the meta description so it accurately and specifically summarizes the
  visible content
- Add `coverImage` + `coverImageAlt` + `ogImage` if missing
  - Search Pixabay/Unsplash/Pexels for wide hero image (1200x630)
  - Or generate custom SVG cover via `blog-chart` (text-on-gradient with key stat)
  - Or generate custom AI image via `blog-image` sub-skill when available; record the model ID
- Verify tags/categories are appropriate

#### 4c. Apply Purpose-First Formatting
State the point of important sections early, then add the verified evidence and
context each claim needs. Do not force statistics or word bands.

#### 4d. Replace Fabricated Statistics
- Search for patterns: "X% of...", "X out of Y...", unsourced claims
- Replace with real data from tier 1-3 sources
- Give each material claim enough provenance to verify and interpret it. Include
  publisher or document details, relevant dates, methodology, limitations, and a
  stable URL when the claim requires them; do not force a fixed citation form.

#### 4e. Improve Headings
- Use question or declarative headings according to reader intent; no ratio target
- Ensure keyword appears in 2-3 headings naturally

#### 4f. Fix Paragraph Length
- Split paragraphs only when doing so improves comprehension
- Use paragraph length as an optional planning observation, not a fixed target
- Ensure each paragraph starts with its most important sentence

#### 4g. Add Visual Elements
- Embed new images after H2 headings, spaced evenly
- Embed charts within relevant sections
- If `blog-image` is available: generate custom images for sections lacking good stock matches, prefer the current image model registry, and record the model ID
- Adapt embed format to detected platform (MDX vs markdown vs HTML)

#### 4h. Add Video Embeds
If the post lacks YouTube video embeds:
- Search 2-3 relevant videos using quality criteria from `skills/blog/references/video-embeds.md`
- Embed using platform-appropriate format (srcdoc lazy loading)
- Place: 1 after introduction, 1-2 in mid-article sections
- Include noscript fallback for AI crawlers

#### 4i. Add/Improve FAQ
- If the query set warrants it and no FAQ exists, add one (3-5 questions)
- If FAQ exists, ensure answers are complete and contain verified support where needed
- FAQPage is optional entity markup only. Google FAQ rich results were fully retired for all sites on 2026-05-07, so do not make FAQPage a core Google rich-result gate.

#### 4j. Reduce Self-Promotion
- Max 1 brand mention (author bio context only)
- Remove "At [Company], we..." patterns
- Convert promotional sections to educational content

#### 4k. Evidence-Backed Explanation
For important claims, generate or improve a self-contained explanation with
enough context and verified support to stand on its own. Do not pad every H2.
- Placed naturally within the section body, not as a separate callout

Example:
```markdown
[Verified source title], a [method or sample description] published on [date],
found [specific metric] for [audience or market] ([Source name](https://example.com/full-report),
retrieved YYYY-MM-DD). In practical terms, connect the evidence to one action
the reader should take before making a claim or changing a workflow.
```

Do not pad explanations to a fixed length or add them solely to earn readiness
points.

#### 4l. Project Voice and Repetition Review
Apply these transformations only where they improve the configured voice:
- **Eliminate em dashes** - Replace every U+2014 character with a comma, hyphen,
  colon, or period. Split sentences if needed. This is a project style rule.
- **Replace flagged phrases** - Swap every detected AI phrase (from the scan in
  Phase 1 step 3) with a natural alternative. Examples:
  - "it's important to note" -> "worth noting" or "keep in mind"
  - "in today's digital landscape" -> "right now" or "in [specific year]"
  - "leverage" -> "use", "apply", "take advantage of"
  - "delve" -> "look at", "explore", "dig into"
  - "robust" -> "strong", "solid", "reliable"
  - "crucial" -> "key", "essential", "critical" (or restructure the sentence)
- **Vary sentence length deliberately** - After rewriting, scan each paragraph.
  Inject short punchy sentences (5-10 words) between longer ones (18-25 words).
  Target: no more than 3 consecutive sentences within 5 words of each other's length.
- **Use rhetorical questions sparingly** - Add one only when it clarifies the
  reader's next decision.
- **Use contractions naturally** - Replace formal constructions with contractions
  where they sound natural: "it is" -> "it's", "we have" -> "we've",
  "do not" -> "don't", "is not" -> "isn't".
- **Support first-hand language** - Keep "we tested" or "in our experience" only
  when methodology, observations, or evidence can substantiate the claim.

#### 4m. Summary Box (Key Takeaways)
If the post lacks a summary box, add one immediately after the introduction:
```markdown
> **Key Takeaways**
> - [Core finding with statistic and source]
> - [Second key insight or recommendation]
> - [Third actionable takeaway]
> (Use concise bullets sized to the material. Keep the summary self-contained so the reader gets
> the core value without reading the full article.)
```
Default label is "Key Takeaways", but this is configurable per persona or
brand voice (e.g., "The Bottom Line", "Quick Summary", "What You Need to Know").

If an existing TL;DR box is useful, convert it to concise Key Takeaways and
verify every factual statement is supported. Do not add a statistic merely to
fit the format.

#### 4n. Information Gain Marker Injection
Review the post for original value and tag it:
- `[ORIGINAL DATA]` - Any proprietary data, survey results, experiments, or
  case study metrics the author collected first-hand
- `[PERSONAL EXPERIENCE]` - First-hand observations, lessons learned
- `[UNIQUE INSIGHT]` - Novel analysis, contrarian perspectives backed by data

If the post lacks original value markers:
- Ask the author for first-hand data or experience to include
- At minimum, add analytical insights that connect existing research in new ways
- Target: at least 2-3 markers per post

Use HTML comments (`<!-- [ORIGINAL DATA] -->`) or visible callouts depending
on the post's style.

### Phase 5: Verification

After rewriting, verify all quality gates pass:

#### Core Quality Gates
1. Important claims state their point clearly and include verified support where needed
2. Paragraph and sentence pacing suits the audience; length alone cannot fail review
3. Zero fabricated statistics
4. Heading hierarchy is clean
5. Article-priority schema present and valid; FAQPage only if useful as optional entity markup
6. Images have descriptive alt text
7. Cover image present in frontmatter (coverImage + ogImage)
8. If MDX: build the project to verify no compilation errors

#### New Element Verification
9. Optional summary is useful and contains no unsupported claims
10. Any information-gain markers identify supported original material
11. Important reusable claims are self-contained and evidence-backed
12. Internal linking zones marked or actual links present (5-10 per 2,000 words)
13. Configured project style-list terms reviewed in context

#### Editorial Style Check
14. Sentence-length variation reviewed descriptively, with no authorship verdict
15. Contractions used naturally throughout
16. Rhetorical questions used only where useful
17. No unsupported first-hand claims
18. Score improved across all 5 categories vs Phase 1 audit
19. YouTube video embeds present with lazy loading, aria-labels, and noscript fallback

## Phase 5.5: Delivery Contract Enforcement (v1.9.0)

Before presenting the rewritten draft, run the 5-gate delivery contract per `skills/blog/references/blog-delivery-contract.md`. The contract applies to rewrites the same way it applies to new posts: the user is never the first reviewer.

Steps:

1. **Hero check**: if the existing post already has a hero image referenced and still on disk, keep it. If the rewrite changed the topic substantially OR the hero is missing, regenerate via `python3 scripts/generate_hero.py --topic "<new title>" --tags "<tags>" --out <folder>`.
2. **Re-render**: run `python3 scripts/blog_render.py --md <slug>.md --out-dir <folder>` to refresh the `.html` and `.pdf` from the updated `.md`.
3. **Reviewer dispatch**: dispatch the `blog-reviewer` agent against the rendered `.html`. Threshold: score 90/100 or higher AND zero P0 issues.
4. **Preflight**: run `python3 scripts/blog_preflight.py --draft <folder> --strict`. Exit 0 = ship; exit 1 = block.
5. **Iterate on failure**: maximum 3 iterations. After the 3rd failure, STOP and present the diagnostic from `<folder>/preflight-report.json`.

Rewrites have a higher implicit threshold because the existing draft was presumably already published. Re-presenting something worse than the original is not acceptable. If the rewritten score is lower than the original score, that itself is a P0 condition.

## Update Mode

When invoked as `/blog update <file>`, focus on freshness:
1. Update statistics to latest available data (2025-2026)
2. Add new developments since last update
3. Refresh images if older than 1 year
4. Update `lastUpdated` in frontmatter
5. Preserve the existing structure - minimize rewrites
6. Target: genuine freshness only. Replace stale statistics, add real new developments, and update `lastUpdated`/`dateModified`; do not rewrite to hit a percentage-change threshold.
