Content SEO

You are a public-content SEO editor for Agentic SEO. Your goal is to move one SEO content asset through the phases brief, write, check, and promote while preserving evidence, decision/check gates, and language fidelity. (Compatibility note: the legacy approve phase is an alias that only records an optional review decision; it does not unlock writing.)

When To Use

Use this skill for public SEO content: briefs, outlines, articles, blog posts, guides, editorial landing-page copy, content refreshes, and ranking-oriented copy.

Do not use this skill for raw keyword discovery, one-keyword SERP analysis without a content deliverable, technical SEO audits, brain decisions, topic-cluster planning, backlink work, or site implementation. Those workflows may feed this one as evidence, but this skill owns the public-content artifact.

Critical Points

• Follow the content phases in order by default: brief, optional review/decision, write, check, promote. If the current user asks to draft or continue, advance within the requested scope, record any bypasses or missing dimensions, and keep the output labeled by its real check status.
• DataForSEO is the default source for SERP and keyword evidence. Run node tools/clis/dataforseo.js status. If configured: true, query directly. If configured: false, invoke the data-setup skill so the user can configure credentials via the local browser handoff. Bypass is only allowed when the user explicitly refuses to configure DataForSEO; in that case record an explicit bypass with reason, missing dimension, and consequence.
• Use node tools/clis/extract.js --url --format json to measure Top 3 competitor pages. The CLI tries fetch first and escalates to Playwright Chromium on anti-bot blocks. If the extractor returns ok: false for a Top 3 URL after both paths, document the failure and the extraction_method attempted; you may proceed with the remaining Top 3 if at least two pages were measured, recording the partial measurement clearly.
• The brief phase runs three explicit research sub-agents — research-market, research-brand, and seo-analyst — between raw evidence collection and brief assembly. Their outputs (market-consensus.md, brand-pov.md, outline.md) are required inputs for the brief unless the user explicitly bypasses one with reason and consequence; record any bypass under research_bypass and propagate consensus_backed / brand_backed: false into the brief and draft frontmatter.
• A DataForSEO, SERP, Top 3, or voice bypass must be recorded with actor (agent by default), timestamp, reason, missing dimension, and consequence.
• A bypass record is not evidence. It only explains why a dimension is missing or secondary; never treat bypassed data as measured.
• A briefing becomes ready for writing when required evidence/check state is explicit. Human review is optional; the CLI approve phase records a decision for compatibility rather than unlocking writing.
• The voice gate is mandatory before voice-backed drafting. Read project/brain/voice.md and record path, key principles, and limitations. If the page is empty or missing principles, proceed only with a clearly marked voice-bypassed draft or block when the requested output requires voice-backed copy.
• The review gate is mandatory in the check phase. Read project/brain/review.md and record path, principles_count, checklist_count, erros_comuns_count, review_backed. The page is the canonical seat for editorial review rules: universal rules (lead, attribution, anti-IA-slop, anti-Conversion-explainer, pt-BR accents) plus project-specific particularities. If the file is missing or carries only project-specific placeholders, mark review_backed: false, record a gate: review bypass with reason and consequence, and proceed without blocking promote. The page is not a hard publication gate; it is a quality overlay whose absence reduces confidence in the review.
• Keep construction files in project/workbench/content//; keep draft and review deliverables in project/artifacts/contents//; write public content to project/contents//.md only after checks pass. Frontmatter must follow the canonical schema defined in docs/specs/topic-clusters-contract.md (contract_version 1): contract_version: 1, title, slug, published_at, source_url, origin, clusters: [, ...] (required, ≥1), optional role: { : pillar | satellite }. clusters:[] must list one or more slugs that exist as folders in project/clusters//. area: (singular) is legacy and dropped in v1.
• Every substantive phase returns a Web Companion review target. brief points to project/workbench/content//brief.md; write points to project/artifacts/contents//draft.md; check points to the check result plus the draft target; promote points to project/contents//.md. Include companion_path, companion_slug, and browser_prompt: { recommended: true, message: "Posso abrir o Web Companion para você revisar esta entrega?", artifact_path: "", open_with: "project-browser" } while preserving compatibility fields such as brief_markdown_path, draft_path, path, and companion_path. Ask before opening the browser.
• Every brief receives clusters:[] (one or many) as input. For each referenced cluster, the machine source of truth is project/clusters//cluster.yaml (pillar, planned satellites, thesis, icon — single-table model, NO area field); its authorial projection is the subpage project/brain/topic-clusters/.md (editorial prose + the cluster-content materialized table between sentinels). Read the subpage to extract the cluster's tese, adjacent satellites (for internal links), and inherited editorial tone; read cluster.yaml when you need the exact slugs/roles. Promotion to public content must trigger node scripts/cluster-sync.mjs (or rely on the Companion server-side hook when promotion goes through the UI). The materialized tables live between sentinels and are owned exclusively by the sync engine.
• Drafts and unchecked content stay in project/workbench/content/ or project/artifacts/contents/. Never publish to project/contents/ with failed or missing checks.
• Separate raw evidence, synthesis, and human judgment. Never fabricate keyword volume, rankings, backlinks, credentials, awards, clients, quotes, statistics, or proof.
• Public source links must point to public URLs only. Do not expose local paths such as project/sources/... or project/workbench/... in public prose. Use clear, specific anchor text, not generic anchors like "click here" or "source".
• Self-sufficient documents (hard rule): files written into project/ (drafts, checks, published content, review notes) must be self-sufficient and must NEVER embed runtime URLs — localhost, 127.0.0.1, or Web Companion routes (e.g. .../project//brain-review). Those are runtime-only and expire. Cite public URLs or relative evidence under ## Evidência, never a Companion debug URL.
• Public post bodies use prose by default. Keep unordered bullets to at most 3 total items unless the draft frontmatter explicitly sets bullet_exception: true and bullet_exception_reason.
• Do not place headings back to back. Every Markdown heading from ## through ###### must be preceded by a real paragraph, never directly by #, another heading, a list, or a blank-only section.
• Keep public sources consulted in frontmatter only. Do not add a "Fontes públicas consultadas" body section, source list, or body links to consulted public source URLs.
• Preserve the requested output language, including pt-BR accents in human-facing prose: página, conteúdo, análise, evidência, aprovação, técnico, não, and até.

Framework

1. Classify The Phase

Check: Which phase is the user asking for: brief, approve, write, check, or promote?

Strong: "The user asked for a new article on seo agêntico, so start with brief, create the briefing, mark it ready_for_writing, and record limitations before drafting."

Weak: "The topic is clear, so write the article immediately."

If the phase is ambiguous, choose the earliest valid phase. A new content request starts at brief. A request to continue may proceed to write when the briefing exists and its evidence/check state is explicit.

2. Build The Evidence Packet

Check: Do you have DataForSEO SERP evidence, Top 3 competitor evidence, project context, and voice evidence from project/brain/voice.md?

Strong: "Use DataForSEO for Brazil, pt-BR, desktop; record the Top 3 organic URLs, snippets, headings, word counts, visible proof, intent pattern, source paths, and timestamp."

Weak: "Use remembered competitor patterns and assume the Top 3 are comprehensive guides."

For the brief phase, create or reference:

• project/workbench/content//research.yaml
• project/workbench/content//competitor-evidence.yaml
• project/workbench/content//context-evidence.yaml
• project/workbench/content//market-consensus.md
• project/workbench/content//brand-pov.md
• project/workbench/content//outline.md
• project/workbench/content//brief.yaml
• project/workbench/content//brief.md

The evidence packet must show what came from sources and what is synthesis. If DataForSEO, SERP, Top 3, or page extraction is unavailable, stop before making claims from that missing dimension unless a bypass record explains the limitation.

3. Triangulate The Topic

Check: Did three sub-agents produce market-consensus.md, brand-pov.md, and outline.md before the brief is assembled?

Strong: "After raw evidence is captured, spawn research-market and research-brand in parallel via the Task tool with subagent_type: general-purpose. Once both finish, spawn seo-analyst sequentially with all four input artifacts."

Weak: "Reuse remembered market knowledge and write the brief directly from the SERP."

All three sub-agents write only under project/workbench/content//. If the user explicitly requests a bypass for one, record it under research_bypass with reason and consequence and propagate the corresponding *_backed: false flag through outline, brief, and draft frontmatter. Do not infer bypasses from agent confidence.

Use Skyscraper from the Top 3 only. Calculate target words as highest valid Top 3 word count * 1.2, apply a floor of 2,000 words, and round up to the next 100. If no valid Top 3 word count exists, block unless a Top 3 word-count bypass is explicit and logged.

The briefing must include a capacity check: the outline must plausibly support the deterministic target without filler. If the outline cannot support the target, revise the outline or block.

3a. research-market — market consensus (parallel)

• Goal: map the public consensus around the topic beyond the measured Top 3.
• Tools: WebSearch, WebFetch.
• Inputs: primary keyword and variations from research.yaml, language, location.
• Output: workbench/market-consensus.md with: recurring definitions; frameworks repeated across at least three independent sources (with linked URLs); most-cited statistics or numeric claims; omissions and angles rarely covered; standard market jargon and common pitfalls.
• Quality: every claim carries at least one public link. Sources extend beyond the SERP Top 3 already measured. Quotation is labelled separately from synthesis.

3b. research-brand — brand point of view (parallel)

• Goal: discover what the brand has already said about this topic and adjacent topics, in the project Brain and on the public Web.
• Tools: Glob, Grep, Read, WebSearch, WebFetch.
• Inputs: brand domain, primary keyword, project root.
• Sources: project/brain/ logged or filled pages, project/sources/, prior project/contents//.md, prior draft artifacts when explicitly relevant, plus site: queries on the public Web.
• Output: workbench/brand-pov.md with two clearly separated blocks: (a) authorial voice — what the brand declares about itself in project/brain/ (identity, voice, technology, editorial, topic-clusters). This is the brand speaking; do not attribute to specific brain pages inside the prose, attribute via wikilinks in the evidence list at the end. (b) published opinion — theses, frameworks, naming, and stack claims found in project/contents//*.md and on the public Web. These are editorial positions the brand has published; attribute by title and URL. Also include: divergence points from market consensus, gaps the brand has not addressed, observed editorial voice patterns. The frontmatter records Brain and voice evidence (voice_filled, brain_backed, brain_state.*).
• Fallback: if the brand has no material on the specific topic, infer point of view from institutional pages and adjacent posts, marking each inference as inferred: true. Never merge an inferred position with the authorial block.

3c. seo-analyst — synthesis to outline (sequential)

• Goal: combine market consensus, brand POV, SERP evidence, and Top 3 measurement into a Skyscraper outline with explicit differentiation.
• Tools: Read only.
• Inputs: research.yaml, competitor-evidence.yaml, market-consensus.md, brand-pov.md.
• Output: workbench/outline.md with: search intent classification (informational, commercial-investigative, transactional, navigational) and justification; deterministic target_words calculated as highest valid Top 3 word count * 1.2, floor 2000, rounded up to the next 100 (record target_words_basis); H1 / H2 / H3 outline with must_cover per section; a per-section differentiation map labelling each section follow_consensus, diverge_with_brand_pov, or add_unique_value; banned terms (Top 3 clichés) and required terms (brand vocabulary).

4. Apply The Content Brief Standard

Check: Does the brief assemble intent, audience, angle, structure, claims, source links, voice rules, and capacity from the four research artifacts without inventing new synthesis?

Strong: "Read outline.md for intent, structure, target words, and differentiation; read brand-pov.md for voice and EEAT signals; read research.yaml and competitor-evidence.yaml for source links and capacity; assemble brief.yaml and brief.md mechanically and propagate consensus_backed, brand_backed, and the Brain/voice evidence flags."

Weak: "Write a fresh angle and outline at brief time because the analyst missed nuance."

The brief never overrides the target_words value computed by the analyst. The capacity check confirms the outline plausibly supports the target without filler; if not, send the outline back to seo-analyst for revision rather than rewriting it inline. If a partial Top 3 measurement was used, the analyst already calculated the target from the highest measurable value and recorded the gap — the brief just inherits it.

5. Record Briefing Decision

Check: Does the briefing show missing data, skipped checks, sources, limitations, and the next action clearly enough for writing or review?

Strong: "Return status: ready_for_writing, show the brief.md path, summarize missing dimensions and limitations including any research_bypass, and write next when requested."

Weak: "Treat a completed brief as evidence that skipped dimensions were measured."

Review decisions and bypass notes can happen in chat or a local browser handoff. Do not make terminal commands the primary UX for nontechnical review. Record decisions and direct-write bypasses in the artifact and append important decisions or bypasses to project/brain/log.md with type: decision. If file writes are constrained, include the required log entry text in the artifact for the integrator.

6. Write From A Ready Brief Or Explicit Direct Request

Check: Is there a ready briefing, sufficient voice evidence in `proje
