A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
End-to-end engine for building organic search traffic. Ships dozens of programmatic landing pages — alternatives, comparisons, use-cases, playbooks — backed by real keyword research, with a persistent roadmap the user resumes across sessions.
Conversion-first (alternatives + comparisons before blogs). Publish-early (a thin page indexed today beats a perfect page indexed in three weeks). Stack-native (writes into the user's framework — Next.js, Astro, Rails+Inertia, or a portable markdown fallback).
| Mode | When | What it produces |
|---|---|---|
| Initialize | docs/seo-machine.md does not exist | Stack detection → brand context → keyword research → tech audit → roadmap + link inventory |
| Resume | docs/seo-machine.md exists | Reads the tracker, picks the next pending phase (or one the user names), executes end-to-end through the quality gates |
Detection rule on every invocation: check docs/seo-machine.md at repo root (or the path recorded in .seo/config.json). No file → Initialize. File exists → Resume. The user does not need to remember which mode they're in.
The roadmap orders patterns by conversion intent first, traffic intent second. This is the single most important decision the skill makes — it's why the alternatives + comparison pages ship before the playbooks + blog posts.
| Order | Pattern | Why | Cost |
|---|---|---|---|
| 1 | /alternatives/[competitor] (Pattern A) | Highest conversion intent — the reader is already in market | ~4 hours per page |
| 2 | /compare/[a]-vs-[b] (Pattern D) | Be the third option in any two-vendor comparison | ~3 hours per page |
| 3 | /for/[use-case] and /for/[audience] (Pattern B/C) | JTBD without competitor name in query — high TP/volume ratio | ~4-5 hours per page |
| 4 | /playbooks/[topic] (Pattern E) | Authority + AI-citation surface area + inbound link draw | ~2-3 days per page |
| 5 | /blog/... (out of scope here) | Lowest conversion intent; defer until ~10 indexed pages exist | — |
Why this order matters: alternatives pages convert 5–20× blog posts at 1/10 the search volume. Shipping one alternatives page is worth ten generic blog posts on the same topic. The roadmap should reflect this — Phase 0 (tech audit) → Phases 1–N (alternatives, then comparisons, then use-cases) → late phases (playbooks) → never (blogs, unless explicitly requested by the user).
Striking-distance boosts (pages already ranking pos 5–20 in GSC) jump the queue when they exist — fastest wins per hour of work.
brand/keyword-plan.md, positioning.md, competitors.md, audience.md, stack.md. Missing files are fine. Brand context loaded:
├── Keyword Plan ✓/✗ (seeds the roadmap; ✗ → generate during Initialize)
├── Positioning ✓/✗ (drives /compare and /alternatives angles)
├── Competitors ✓/✗ (target list for /alternatives pages)
├── Audience ✓/✗ (intent buckets for /for/<persona> pages)
└── Stack ✓/✗ (selects references/stacks/<framework>.md)CLAUDE.md, README.md, package.json, design tokens, existing marketing pages) during Initialize Step 2. With full brand context it skips re-discovery and goes straight to research + roadmap.| # | Check | Failure mode |
|---|---|---|
| 1 | git rev-parse --is-inside-work-tree succeeds | Stop. Tell the user this skill writes a persistent roadmap; initialize git or run from a repo. |
| 2 | A stack is detectable — one of package.json, Gemfile, composer.json, requirements.txt, astro.config.*, next.config.*, nuxt.config.*, gatsby-config.*, _config.yml, config.toml, pyproject.toml | Ask the user what stack they're on before continuing. |
| 3 | Research backend resolved (see below) | Never refuse to run — fall through to manual mode. |
Research backend resolution order (record the choice in .seo/config.json under research_backend):
mcp__exa__web_search_advanced_exa with a minimal query. On success, use the full Exa research stack — Exa MCP + Firecrawl (SERP scrape) + gh (OSS competitor signal) + /last30days skill (Reddit/X/HN aggregation) + mktg-x (auth-walled Twitter) + the mktg-native company-research / people-research skills. The 7 Exa-native recipes in references/exa-recipes.md replace the Ahrefs cookbook entirely; the cross-API compound recipes in references/api-stack-recipes.md add capabilities Ahrefs alone can't do (pain-point clustering, OSS competitor teardown, outreach prospect discovery, newcomer surveillance).references/manual-research.md (free Google + Search Console + paste-from-UI fallback).Ahrefs as a footnote: ifmcp__ahrefs__subscription-info-limits-and-usagereturns data AND the user wants numeric volume/KD/TP precision, layer Ahrefs on top of the Exa-stack rather than replacing it. The "Ahrefs appendix" at the bottom ofreferences/exa-recipes.mddocuments which Ahrefs queries upgrade each Exa-native recipe with precise numbers. Ahrefs MCP is intentionally NOT in mktg's chained-in ecosystem table — it's a paid escalation, not a default dependency.
Goal: end the run with a written docs/seo-machine.md containing keyword research, a phase tracker grouped by pattern, and technical-audit findings — plus .seo/brand.md and .seo/link-inventory.md.
Read references/stacks/detection.md. Identify framework family, routing convention (file-based vs controller-based), component language, and existing marketing pages (git ls-files | grep -iE 'marketing|landing|pages/(home|about|pricing)'). Resolve ambiguity with AskUserQuestion. Persist to .seo/config.json.
Read every signal first, propose .seo/brand.md, then ask only about gaps. Signals: CLAUDE.md, README.md, package.json / Gemfile.lock, tailwind.config.* or design-token CSS, app/views/marketing/* or pages/index.*, pricing page.
If brand/voice-profile.md and brand/positioning.md already exist (mktg-native project), read them and skip 80% of the questions — those files already say who the buyer is and what the brand sounds like.
Otherwise use a single AskUserQuestion (3–4 questions max) to fill gaps. Required to know:
Write to .seo/brand.md using assets/brand-template.md as the skeleton.
Follow references/exa-recipes.md — 7 Exa-native recipes that replace the Ahrefs cookbook:
| Recipe | Purpose | Primary API |
|---|---|---|
| A. Domain baseline | DR estimate from indexed-page count + brand mentions + GitHub stars (OSS) | Exa company_research_exa + web_search_advanced_exa + gh |
| B. Competitor reverse-lookup | What competitors rank for | Exa web_search_advanced_exa site:<competitor> + AI summary |
| C. Use-case sweep | /for/ and /playbooks/ topic discovery | Exa deep_search_exa + Firecrawl autocomplete + /last30days |
| D. Comparison volume | Validate demand for /compare/[a]-vs-[b] before writing | Exa web_search_advanced_exa + Firecrawl SERP scrape |
| E. SERP saturation | Replaces Ahrefs KD with SERP-composition-derived signal | Exa search + per-result company_research_exa |
| F. Backlink prospecting | Referring-domain proxy via Exa | Exa search + DR proxy (see off-page-seo skill) |
| G. Content gap | Their indexed keywords − ours, ranked by DR-cap fit | Recipes B + own-site Exa lookup |
Then pull cross-API compound recipes from references/api-stack-recipes.md for moves Ahrefs alone can't do — pain-point cluster discovery (/last30days + mktg-x + Exa deep search), OSS competitor teardown (gh + DeepWiki + Exa), outreach prospect discovery (Exa Websets + people-research), newcomer surveillance (Exa Websets cron).
When Exa is unavailable, fall back to references/manual-research.md (paste-from-UI workflow). When the user has paid Ahrefs, layer it on top per the appendix in exa-recipes.md — don't replace.
Cache the raw output to .seo/keyword-research.json. Curate the decision-ready summary into the Keyword Research Appendix section of docs/seo-machine.md.
Run scripts/tech_audit.py (sitemap, robots, meta-tag uniqueness, schema). Whatever it finds becomes Phase 0 in the roadmap. Day-0 crawl shapes Google's understanding of the site for months — retroactive fixes are harder.
Fill assets/roadmap-template.md with:
traffic_potential desc → volume desc → KD ascWrite to the configured path (default docs/seo-machine.md). Print the path back and recommend a human review pass before Phase 0.
.seo/link-inventory.mdEvery phase reads this file to pick internal links. Use assets/link-inventory-template.md. Pre-populate from existing routes (features, tools, pricing, blog posts). Each phase appends to it as new pages ship.

Next: review docs/seo-machine.md, then run me again to execute Phase 0.Do not auto-execute Phase 0. Pattern priorities and competitor lists are decisions worth a human pass.
Goal: pick the next phase from the tracker, execute end-to-end with quality gates, hand back so the user can commit/PR.
Load docs/seo-machine.md, .seo/brand.md, .seo/link-inventory.md, .seo/config.json. Find the Phase Status Tracker, identify the next pending phase with the lowest number, print it back along with the two phases that follow.

| Rule | Why |
|---|---|
| Ask before you guess on positioning calls | The user's gut on which competitor or use-case to ship next often beats the data |
| Show the numbers, not the conclusion | "vol 400, KD 12, TP 1,800" builds more trust than "the data is good" |
| Be honest about what won't work | KD 80 at DR 8 = doomed. Say so, offer the closest winnable alternative |
| One-sentence theory max per phase | The user doesn't need a recap of SEO theory every run |
| Surface tradeoffs, not opinions | "5 thin alternatives or 2 deep ones first?" — state the tradeoff, ask |
| Skill | When | When NOT |
|---|---|---|
seo-audit | One-off diagnostic on an existing site | Forward execution — use this skill |
seo-content | Writing a single rankable article | A whole sprint — use this skill |
competitor-alternatives | One /alternatives/<x> page, ad-hoc | Pattern A as part of a sprint — use this skill |
keyword-research | Producing brand/keyword-plan.md | This skill consumes that artifact — chain them |
ai-seo | LLM-citation optimization for a few pages | Run after this skill ships ~10 indexed pages |
| Don't | Why |
|---|---|
| Target head terms when DR is low | "Social media management tool" at DR 8 is wasted work. KD ≤ DR+10 while DR is low. |
| Ship pages with no inbound internal links | A new page nobody links to is an island. ≥2 inbound links from existing pages, same phase. |
Ship /alternatives pages without an "honesty" section | Three honest tradeoffs (where the competitor wins) is non-negotiable. Brand signal AND Google quality signal. |
| Skip schema markup | FAQPage JSON-LD captures snippets. Article for playbooks. SoftwareApplication for homepage + use-case. Quality gate fails without them. |
| Auto-commit | Always show diff summary; let the user commit (local conventions, hooks, branch naming). |
| Restart Initialize when partial state exists | If .seo/config.json exists without the roadmap, prompt before wiping — they may have aborted mid-run. |

The skill writes to project paths, not brand/. This is why writes: in skills-manifest.json is [] — the manifest declares only brand/*.md writes, and seo-machine's outputs live in the user's repo, not in brand memory.
| Output | Mode | Purpose |
|---|---|---|
docs/seo-machine.md | Initialize (write), Resume (update phase row) | Persistent sprint roadmap — Phase Status Tracker + Reference Data + Keyword Research Appendix. Single source of truth across sessions. |
.seo/brand.md | Initialize | Product context derived from repo + user answers (one-liner, persona, competitors, voice tags, anti-positioning). |
.seo/link-inventory.md | Initialize (create), Resume (append per phase) | Every internal-link target the skill can use. Each phase appends new pages. |
.seo/keyword-research.json | Initialize | Cached raw output from Ahrefs / Exa / manual research. Read by every phase, refreshed every 30 days. |
.seo/config.json | Initialize | Stack info, research backend choice, project IDs. Persists machine-readable state. |
| Phase-specific page files | Resume (per phase) | Stack-native page files (e.g. app/controllers/marketing_controller.rb + app/frontend/pages/Alternatives/Show.tsx for Rails+Inertia; app/[pattern]/[slug]/page.tsx for Next.js App Router; etc.). Paths follow references/stacks/<framework>.md. |
This follows the Long-Arc Sprint Persistence Pattern documented in AGENTS.md — docs/seo-machine.md is the canonical doc that survives session interruption.
/cmo routes here under Playbook #9 — SEO Authority Build, Path B (programmatic sprint). On a cold project /cmo first spawns mktg-brand-researcher, mktg-audience-researcher, mktg-competitive-scanner in parallel (foundation), runs keyword-research to populate brand/keyword-plan.md, then hands off here. After every phase, /cmo spawns mktg-content-reviewer + mktg-seo-analyst in one message to score the page batch before the user commits.
